Description
FIELD OF INVENTION
[0001] The invention relates to a system having a ground drilling
device with a control device for operating the ground drilling
device, wherein the system moreover comprises an input device
functionally coupled to the control device for entering at least
one parameter for the operation of the ground drilling device, a
method for controlling the operation of a ground drilling device,
and a use of a ground drilling device.
BACKGROUND
[0002] Ground drilling devices are generally operated by a user who
is positioned at a driver's station, usually an operator's cabin.
At the driver's station, there is arranged a seat for an operator
and the operator can control the operation of the ground drilling
device by means of at least one activating element, particularly a
multifunction joystick. Usually other persons besides the operator
are needed on site, in order to monitor and/or conduct the
operation and the success or activities required for the
drilling.
SUMMARY
[0003] The problem which the invention proposes to solve is
therefore to create a system, a method, and a use with which the
expense for making a borehole by means of the ground drilling
device can be reduced, especially the expense in the form of
providing a smaller number of operating and/or monitoring
persons.
[0004] The key idea of the invention is to configure an input
device, which is intended for the entry of at least one parameter
for the operation of the ground drilling device, as a remote
control. The configuring of the input device as a remote control
creates the possibility of the operator, heretofore located at the
driver's station, choosing their location more freely in regard to
the control of the ground drilling device. No longer must the
operator remain at the driver's station in order to control the
ground drilling device. Thanks to the free possible positioning of
the operator, he can be present at other possible locations while
controlling the ground drilling device and thus be present at the
same time as controlling the ground drilling device at a location
where formerly another operator had to be present in order to
perform or monitor an activity in connection with the introducing
of the earth borehole in the soil. Since the activity can now also
be performed by the operator otherwise present at the driver's
station, the additional operator is not needed. The operator
formerly required can now be given other jobs, so that the work
force and/or the costs of providing the work force for the
introducing of a ground drilling device can be reduced. An added
value is possible for the firm utilizing the ground drilling
device.
[0005] The invention creates a system comprising a ground drilling
device having a control device for operating the ground drilling
device. The system moreover comprises an input device functionally
coupled to the control device for entering at least one parameter
for the operation of the ground drilling device. In particular, the
parameter may bring about a starting of the drilling with the
ground drilling device or a stopping of the drilling performed with
the ground drilling device. The input device is designed as a
remote control.
[0006] A "ground drilling device" in the sense of the specification
encompasses any device which moves in particular a drill string
having rod sections in an existing or yet to be created conduit in
the soil, in order to create or widen a borehole, particularly a
horizontal borehole (HD), or to draw pipelines or other long bodies
into the soil. The ground drilling device may be in particular a HD
device. The term "HD" (horizontal drilling) in the sense of the
present specification encompasses in particular an at least partly
horizontal borehole or conduit or pipeline. A ground drilling
device may be in particular a device driving a drill string
operating by displacing earth, and introducing the drill string
into the earth by rotation and/or translation in the longitudinally
axial direction of the drill string. A borehole can be introduced
into the soil by pulling or pushing on the drill string. The term
"rod section" in the sense of the specification encompasses not
just rigid force transmitting elements which can be connected
directly or indirectly to each other and which can be used in a
ground drilling device.
[0007] A front-end section of the drill string may be configured as
a drilling head or drilling tool. Moreover, the drill string may
have a probe housing, particularly in a front-end region.
[0008] The term "control device" in the sense of the specification
encompasses an embodiment of a control system by means of which a
directional influencing of the ground drilling device is possible
in operation, i.e., during the making or at the starting or
stopping of an earth borehole. The control device in particular may
be electrical or electronic. The parameters entered by an operator
can be used by the control device as input for the operation of the
ground drilling device--optionally transformed and/or processed
into electrical signals. The ground drilling device can thus be
operated or controlled by means of the entering of a parameter,
possibly transformed into an electrical signal.
[0009] By a "parameter" in the sense of the specification is meant
a data entry with which a directional influencing of the operation
of the ground drilling device is possible. The parameter may be
relayed as an input signal to the control device, by means of which
the control device controls the operation of the ground drilling
device. A parameter may, for example, bring about a starting of the
drilling with the ground drilling device or a stopping of a
drilling being carried out with the ground drilling device. For
example, it is possible for an operator to enter the parameter
"Start" and an input signal appropriately coordinated with the data
entry will be relayed to the control device, which causes a
starting of the drilling. In similar fashion, an operator may enter
the parameter "Stop" and a corresponding input signal related to
this will be relayed to the control device, which causes a stopping
of the drilling performed with the ground drilling device. Other
parameters influencing or altering the operation of the ground
drilling device are possible, these parameters being entered by an
operator and being transformed by the input device into an input
signal and relayed to the control device.
[0010] The term "input device" in the sense of the specification
encompasses any electrical or electronic device which is suited to
transforming a data entry by an operator into an electrical signal,
which may be relayed to the control device with no further
processing or by way of an interposition of circuitry for
processing of the signal, particularly a processing in one or more
circuits, such as an amplifier, in order to be used as input or as
an input signal of the control device. The input device can be
understood as being an interface between an operator and the
control device. The input device may comprise a portable power
supply, particularly in the form of one or more batteries, storage
cells, or the like.
[0011] The input device in particular may comprise a processor,
being designed as a computer with electronic circuits, in order to
execute commands. The input device may have an operating system,
which can be modified for example for an improvement and/or
adaptation to changes in a ground drilling device. A change in the
operating system can then only be allowed, in particular, with a
password and/or when the input device is connected to an interface
of a computer, a dongle, or the like. In particular, the processor
can recognize the data entry of an operator in the form of
parameters, retrieve them, process them, forward them on, and/or
handle other commands of a program. The processor can work off a
program which requests or receives the data input of an operator,
process the data entry of the operator, make adjustments to the
data entry of the operator, transfer the data input to the control
device and/or receive, process, and/or transform signals from the
control device.
[0012] The term "functionally coupled" encompasses in the sense of
the specification a connection of the mentioned devices,
particularly a unidirectional or bidirectional one, in order to
provide signals from one of the devices, particularly the input
device, and to receive signals with the other device, particularly
the control device, and/or to process the signals received. The
functional coupling can be direct or indirect through the
interposition of other elements or devices.
[0013] A "remote control" encompasses in the sense of the
specification a handheld electrical or electronic device which is
suited to controlling the operation of the ground drilling device
at a distance from it by the entry of a parameter. In the sense of
the specification, "at a distance from the ground drilling device"
should be taken to mean that a direct entry by means of a device
fastened to the ground drilling device is not necessary. In
particular, an operator outside the driver's station of the ground
drilling device can control the operation of the ground drilling
device by entry of a parameter for the operation of the ground
drilling device.
[0014] In one preferred embodiment, the entry of the at least one
parameter is [0015] a) a setting of a torque and/or a rotational
speed applied to a drill string of the ground drilling device, (b)
a setting of a linear advancing force and/or a linear advancing
speed of a drill string, (c) a setting of an impact rate of a main
piston, (d) a setting of an impact amplitude of a main piston, (e)
a setting of a flow rate and/or a pressurization of drilling mud,
(f) a changing of the drill string, (g) a lubricating of the drill
string, and/or (h) a changing of the drilling head type.
Consideration may be given to which string is involved. In
particular, in a double-pipe string, the torque and/or the
rotational speed can be chosen independently for an inner pipe
string, so that both torque and/or rotational speed can be set
independently for an inner pipe string and/or outer pipe string. In
this way, basically any entry can be done which is relevant for the
drilling operation of the ground drilling device. Besides the
starting or stopping of a drilling performed with the ground
drilling device, the aforementioned parameters can be relayed to
the control device.
[0016] For the setting of a torque/rotational speed applied to the
drill string of the ground drilling device, a signal can be relayed
from the control device in dependence on the parameter entered by
the operator using the input device to the drive unit of the ground
drilling device, which is connected to the drill string, so that
the torque/rotational speed chosen by the operator can be adjusted.
The parameter may be a signal corresponding to the magnitude of the
torque/rotational speed. The setting of a linear advancement of the
drill string can set both the force or the pressure and/or the
speed with which the drive acts on the drill string connected to
the drive. The setting of the linear advancement may also include
whether the linear advancement is a tensile or compressive force,
i.e., whether the drill string is pulled or pushed through the
soil. Accordingly, the term advancement encompasses both
directions, both a pulling and a pushing of the drill string, so
that a pulling or a pushing force can be applied to the drill
string. Hence, the parameter can be a signal corresponding to the
tensile or compressive force. When introducing a borehole in the
soil, drilling mud may be used, particularly in the form of
bentonite. The drilling mud can be taken through the drill string
and emerge at the front end region of the drill string. The
parameter set can be a flow rate or pressure of the drilling mud,
which can be adapted to the conditions in the soil. When drilling
with a drill string, it is necessary to lengthen the drill string
during the course of the drilling, and in particular additional rod
sections are connected to the drill string already introduced in
the soil. For this, a data entry may be needed to perform a string
change, i.e., the connecting of an additional rod section,
particularly one from a rod magazine, to the drill string already
introduced. Thus, the parameter may be an activation corresponding
to the command "Perform string change now". During the string
change, the drill string already introduced in the soil is clamped,
in order to fix the axial and/or angular position of the already
introduced drill string. Moreover, the entry of the parameter may
involve a changing of the drill head type, which may be required
especially when, after performing a pilot borehole, i.e., a first
borehole, which has been made for example by pushing in the soil,
the drill head type is changed to a widening drill head, which is
pulled through the previously created pilot borehole in order to
widen it.
[0017] Insofar as the ground drilling device is designed as a
percussion drilling device, the stroke rate of the main piston of
the percussion drilling device and/or the stroke amplitude of the
main piston of the percussion drilling device can be adjusted. The
term "percussion drilling device" or "displacement hammer", which
is used basically synonymously with percussion drilling device,
encompasses in the sense of the specification a self-propelled
impact apparatus which works by displacement of soil and can
introduce a conduit or a pipe into the soil by percussion. The term
percussion drilling device encompasses earth displacement devices
in which the drilling head tip is arranged lengthwise movably in a
housing. The drilling head tip may be in particular a drill bit. A
percussion drilling device can be both a single-stroke and a
multiple-stroke device. In a single-stroke device, the main piston
strikes the drilling head tip and at the same time the housing. In
a multiple-stroke device, particularly a two-stroke device, the
main piston at first strikes the drilling head tip, which moves
ahead during the first stroke. The housing is struck in a following
stroke, particularly in the second stroke. Tip resistance and
casing friction are separate in a multiple-stroke device and thus
are easier to overcome.
[0018] In one preferred embodiment, the input device comprises at
least one mechanically operated activating element. The
mechanically operated activating element may be any mechanically or
manually operated activating element. A rotary switch, a control
stick and/or a pushbutton are preferred embodiments of a
mechanically operated activating element. Different kinds of
activating elements are possible on the input device. Multiple
activating elements of the same kind may be provided on the input
device.
[0019] A control stick in the sense of the specification is an
activating element for the entering of two-dimensional signals in
particular. A control stick may comprise an element extending from
a surface, which can generally be tilted in multiple directions.
The element can be configured in particular as a rod, a piston, a
stick, or a lever. The element can extend from a surface at a
height not greater than 7 cm, preferably 6 cm, preferably 5 cm,
preferably 4 cm, preferably 3 cm, preferably 2 cm, preferably 1 cm.
The diameter of the element may in particular be less than 5 cm,
preferably 4 cm, preferably 3 cm, preferably 2 cm. A control stick
in the sense of the specification may also be called an analog
stick or a joy stick and it may be equivalent in function to this.
The term control stick also encompasses a control pad with which an
entry of two-dimensional signals is possible. The control stick may
generate a signal which is dependent on the position of the element
or the control pad in relation to a standard or resting position of
the element or the control pad. It may be provided that the control
stick provides individual electric signals when activated and/or
continuously provides an electric signal in the form of voltages
and/or currents, wherein a potentiometer can be used respectively
for one of the dimension in which the element or the control pad
can be tilted, for example one potentiometer for the up/down
position and one potentiometer for the left/right position. The
voltage can change due to the change in position or attitude of the
element or control pad of the control stick in relation to the
resting or standard position. The size and/or arrangement of the
control stick on the input device may be adapted such that an
activation is possible by means of the thumb or a finger of an
operator, in particular an activation of the control stick is
possible without grabbing the control stick. Insofar as the control
stick is designed to generate signals in dependence on a movement
in at least two dimensions, this also includes the possibility that
an entry can be provided for a control of the operation of the
ground drilling device by means of a control stick in which the
control stick generates no signals in regard to the movement in one
of the dimensions and/or signals in regard to the movement in one
of the dimensions are not taken into account, or do not need to be
taken into account by the control device.
[0020] A rotary switch or rotary knob in the sense of the
specification may comprise a potentiometer or be formed by such.
Advantageously, the rotary switch is substantially maintenance-free
and not sensitive to vibrations; moreover, in the switched-off
state, a turning of the rotary switch has no effect.
[0021] A pushbutton in the sense of the specification is an
activating element which can be configured as a subassembly which
makes or breaks an electrically conductive connection. The
pushbutton may be designed as a toggle switch or a simple pressure
switch. It has been found to be advantageous for the operating
stroke of a pushbutton to be at least more than 2 mm, in order to
count as a "wanted" activation. Preferably, activating strokes of
more than 2.3 mm are used, and when gloves are worn then activating
strokes of more than 3 mm, preferably more than 5 mm, particularly
preferably more than 6 mm, even further preferably more than 7 mm
may be provided. For the diameter of a pushbutton, it has been
found to be advantageous for the diameter of the pushbutton to be
more than 5 mm, particularly more than 7 mm, for an activation by
means of the finger of the operator. For an activation by means of
the thumb of the operator, the diameter of the pushbutton can
advantageously be more than 15 mm, preferably more than 17.5 mm,
particularly more than 20 mm.
[0022] A selection of mechanically operated activating elements may
be provided at the input device. In particular, customary
activating elements of the prior art can be used to allow the
operator the also customary entry possibilities for the control of
the ground drilling device. The size and/or arrangement of the
activating elements may vary relative to the prior art, in
particular a control stick on the input device may be smaller than
a multifunction joystick situated in the driver's station.
[0023] In one preferred embodiment, at least one mechanically
operated activating element, particularly a control stick, is
arranged as an interchangeable unit in a receiving space of the
input device. In this way, the possibility can be created of
quickly replacing an activating element needed for the operation of
the ground drilling device in order to enable the most continuous
possible operation of the ground drilling device by the operator.
Such a simple replacement may be advantageous, given the use of the
input device outside the driver's station, since the activating
element may be subjected to greater wear and tear.
[0024] In one particularly preferred embodiment, the input device
may comprise at least one capacitive or mechanically operated
activating element and/or a radio transmitter, particularly to
determine whether an operator entrusted with operation of the
ground drilling device is holding the input device or grasping it
with his hands. Accordingly, an activating element and/or a radio
transmitter may be provided to determine whether an operator can
operate the input device or is located in its near field. A
capacitive or mechanically operated activating element can
recognize the presence of the operator as well as a radio
transmitter. For example, a mechanically operated activating
element can determine whether the operator is operating the
respective activating element in order to allow data entry and/or
further operating of the ground drilling device and not to place it
in a protected condition. For example, it may be provided that the
entry of a parameter only occurs when the respective activating
element has positively recognized that the operator is holding the
input device or grasping it with their hands or is operating the
activating element at the same time. In this way, it is possible to
determine for example whether the operator has set the input device
aside, for example in order to perform work on the ground drilling
device or gain access to it, while the ground drilling device is
still performing an earth drilling and driving the drill string. In
such an event, a switching off or a placing of the ground drilling
device in a resting condition can be done. The input device in such
a case relay to the control device a signal corresponding to a
parameter signifying, in a real instruction, "Produce resting
condition" or "Emergency shut off". It may be provided that the
"resting condition" of the ground drilling device differs from the
condition of the ground drilling device after an "emergency
shut-off"; in an "emergency shut-off", a shutting off of the ground
drilling device may occur, whereas in a "resting condition" the
units and/or drives of the ground drilling device continue to be
switched on but are not driven.
[0025] In one preferred embodiment, the sensitivity of the
mechanically operated activating element can be adjusted a)
mechanically and/or b) by means of software, which is functionally
coupled by means of a sensor and a corresponding element to the
activating element. This can create the possibility for the
operator to adjust the sensitivity, particularly that of a control
stick or a rotary switch, even under different conditions, such as
with or without wearing gloves. For example, two different settings
are possible for the sensitivity of a control element: 1) operation
with gloves or 2) operation without gloves. It may also be provided
that the sensitivity can be set in dependence on the kind of the
entry or the parameter. The setting can be undertaken by the
processor in the input device.
[0026] In one preferred embodiment, the input device comprises at
least one particularly two mechanically operated activating
elements, particularly one or two pushbuttons, which are present on
the input device at least so far apart that a two-hands operation
is required. This can create a so-called dead man's switch, with
which it can be verified that an operator is present or able to
act. If it is recognized that no operation of one of the activating
elements is done, then it may be concluded that the operator is not
present and/or capable of acting, so that a signal or a switching
action may be triggered. This can achieved a higher degree of
safety during the operation of the ground drilling device. For
example, an operator may be prompted by means of a haptic signal, a
visual indication, and/or an acoustic signal, to operate the
activating element or both of them; if no operation occurs, a
signal or a switching action may be triggered, which switches the
ground drilling device to a resting state or switches it off. The
providing of two mechanically operated activating elements, only
one of which need be used as a so-called dead man's switch, can
provide the advantage that--when the mechanically operated
activating elements are present both right and left on the input
device--the input device can be easily and ergonomically operated
by both right-handed and left-handed operators. Accordingly, it
will be sufficient to configure a dead man's switch either on the
left or the right side. However, the providing of the two options,
both right and left, takes account of the possible requirements of
the operator.
[0027] In one particularly preferred embodiment, a monitoring
device is present, which can be part of the processor. The
monitoring device is adapted to verifying the operation of two
activating elements at the same time. In addition or alternatively,
it may be provided that a monitoring is done to ensure that the
simultaneously operated activating elements are not operated again
within a predetermined time window. With the aid of the monitoring
device, a time difference can be set in regard to the
"simultaneity" of the triggering of the two activating elements in
the form of a tolerance. There may also be a setting of the time in
which the activating elements need to be released once more. A
simple design of a dead man's switch is possible.
[0028] The input device may have a circumferential outer contour,
particularly an interrupted or closed one, which may enclose an
inner contour or interior of the input device. The circumferential
outer contour may be substantially rectangular, square, polygonal,
round, circular and/or elliptical over the entire area or also only
for a portion. Mixed shapes and combinations of the mentioned
shapes are possible. In particular, it may be provided that the
input device is substantially rectangular or cuboidal and has a
dimension in the range of 15 cm to 50 cm in width, preferably 20 cm
to 40 cm in width, 10 cm to 30 cm in length, preferably 15 cm to 25
cm in length, and 3 cm to 15 cm in height, preferably 5 cm to 10 cm
in height.
[0029] It may be provided that the input device has at least one
protrusion or multiple protrusions, particularly two of them,
particularly in regard to one of the aforementioned shapes, which
may be adapted for grasping by means of the hands of the operator,
in particular, the protrusion or the protrusions may be configured
as a handle. Preferred is a handle configuration which can be
embraced by one hand of the operator. The protrusion or the
protrusions may project beyond the rectangular, square, polygonal,
round, circular and/or elliptical shape of the input device. The
mechanically operated activating elements in particular can be
fashioned on one of the protrusions or on each of them. The
protrusions may be configured on the input device such that a
surface facing toward the operator results by means of the
protrusion or the protrusions, forming a surface which can lie in a
plane in particular. It may be provided that the protrusions stand
off from a surface with the aforementioned shape, particularly to
form entirely or partially a holder, particularly one with the
circumferential outer contour, for an indicator device as described
below in the specification. The protrusion or protrusions may stick
out from a base surface or a base plate. The protrusion or
protrusions may form, at least for a portion, an edge on a base
plate having an aforementioned shape. The protrusion or protrusions
may be offset forwards in relation to the base plate. If multiple
protrusions are present, the protrusions may project in the same
direction relative to a base surface or base plate and form an edge
thereon. The base plate with the protrusion or protrusions may
follow in particular a circumferential outer contour of an
indicator device. The base plate can be entirely closed or it may
have apertures. A wall may project at least partly or in closed
manner at the edge on the base plate, which can enclose at least
partially or entirely on the circumference of an indicator device
described hereafter in the specification.
[0030] A curved adaptation of the protrusions to the shape of the
hands of the operator is possible, particularly as regards the
corners of a protrusion. The particular protrusion may be adapted
to the dimensions of the hand of the operator; in this way, the
input device may be configured in other areas independently of the
hands of the operator; it is possible for an adaptation to the
dimensions and shape of the hands to be present only in the area of
the protrusions. Thus, an adaptation to the dimensions and/or shape
of the hands of the operator, possibly involving a smaller
structural shape, may only pertain to the protrusions.
[0031] The mentioned protrusion or protrusions for a good grasping
by means of one hand of the operator may have a diameter in the
range of 3 cm to 5 cm, preferably 3 cm to 4 cm. The length of a
protrusion particularly for a good holding by one hand of the
operator, particularly in a manner not causing fatigue, may be
larger than 10 cm, preferably larger than 15 cm, in order to allow
for the possibility of the operator wearing a glove, for
example.
[0032] If more than one protrusion is formed on the input device,
the protrusions may be formed on opposite sides of the input
device. A mirror image symmetry of the protrusions is possible. The
mechanically operated activating elements can be formed as mirror
images of each other on the protrusions when multiple protrusions
are provided.
[0033] When the respective protrusion is grasped by the hand of the
operator as intended, a control stick may be arranged on the
protrusion in the area of the thumb. Preferably, a control stick is
arranged on each of the protrusions in the area of the thumb.
Preferably, a mechanically operated activating element fashioned as
a control stick element protrudes from a substantially flat or
noncurved surface. The control stick may protrude from a surface of
the input device facing toward the operator. In particular, a
control stick may protrude from a surface parallel to the base
surface of the input device, which can be established basically by
the circumferential outer contour.
[0034] If a control stick is provided on the input device, a
further mechanically operated activating element, particularly a
rotary switch, can be arranged on a surface of the protrusion
different from the surface for the control stick. Regardless of
whether a control stick is provided, a rotary switch can be
arranged in particular on a surface of the protrusion extending
away from the operator. The surface on which a rotary switch is
arranged can make an angle in particular with a surface facing
toward the operator when holding the input device or on which a
control stick is provided of 10.degree. to 60.degree., preferably
20.degree. to 50.degree.. In particular, the rotary switch may be
arranged such that it can be comfortably operated with the index
finger or middle finger of the operator when the input device is
held, particularly if the operator grasps the protrusion optionally
provided on the input device.
[0035] If a control stick is provided on the input device, a
pushbutton may be arranged in particular on a surface different
from the one provided for the control stick. A pushbutton may be
arranged in particular on a surface of the protrusion extending
away from the operator when the input device is held. The surface
on which the pushbutton may be provided can be opposite the surface
from which the control stick extends, if a control stick is
provided. The surface on which the pushbutton is arranged can make
an angle with a surface on which a control stick is provided of
10.degree. to 60.degree., preferably 20.degree. to 50.degree.. The
pushbutton may be arranged in particular so that it can be
comfortably operated with the index finger, middle finger, or ring
finger of the operator when the operator is holding the input
device, particularly when the operator is grasping the protrusion
possibly provided.
[0036] It may be provided that a pushbutton and a rotary switch are
present on the same surface at a distance from each other, wherein
an operation with different fingers of the operator is possible in
particular.
[0037] Basically three surfaces may be formed on a protrusion of
the input device, on which a mechanically operated activating
element can be arranged each time. The surfaces on which a
mechanically operated activating element is provided can make an
angle with each other. The surfaces may have a curvature. A
mechanically operated activating element designed as a rotary
switch may be arranged preferably on a surface having a curvature,
and the curvature of the surface may basically correspond to the
curvature of the rotary switch, so that an operation of the rotary
switch can occur in particular over an angle range which is larger
than 180.degree., larger than 190.degree., larger than 200.degree.,
larger than 210.degree., larger than 220.degree., larger than
230.degree., larger than 240.degree., larger than 250.degree.,
larger than 260.degree., larger than 270.degree., larger than
280.degree., larger than 290.degree., larger than 300.degree..
Thus, an operating of the rotary switch can be easily done by an
operator who may be wearing gloves.
[0038] A mechanically operated activating element designed as a
pushbutton may be arranged preferably on a surface having a
curvature. A pushbutton may have a curvature basically
corresponding to the curvature of the surface. It may be provided
that an operation of the pushbutton is possible over a large angle
range, which may correspond to the angle range of the curvature. An
operation may occur even if the pushbutton is not operated in a
straight line.
[0039] A structurizing of the input device is possible for at least
partial or complete accommodation of a further device, particularly
an indicator device described below in the specification, wherein
an accommodating in the sense of the specification involves the
possibility of a connection between the two devices, particularly
the input device and the indicator device, which may be with form
fit and/or force locking, in particular.
[0040] In one preferred embodiment, the input device has a not
necessarily flat surface on which at least two activating elements
are arranged in the area of two neighboring corners and/or opposite
edges. The corners and/or edges may also be formed on one or more
protrusions. This makes possible an ergonomically favorable
arrangement of two activating elements for the person performing
the operation. Thus, the principles of an optimal design can be
satisfied. Designs conforming to occupational medicine, user
friendliness, work science or personal body type of the operator
can be taken into account.
[0041] In a particularly preferred embodiment, the input device can
be grasped in the area of the corners and/or the edges--possibly in
the area of a protrusion--by one hand of the operator. Moreover, in
the preferred embodiment, at least one activating element can be
arranged so that it can be reached by one finger or the thumb of
the user, grasping the corners and/or the edges--possibly at one or
more protrusions. It has been discovered that an optimal adaptation
is achieved from an ergonomic standpoint, also taking account of
work science and user-friendly criteria. For example, the input
device may be adapted by the thickness of the corners and/or edges
to the operator's hand, taking into account whether or not the
operator is wearing gloves.
[0042] In particular, the activating elements arranged in the area
of the corners and/or edges may be control sticks. In particular,
the control sticks may be arranged on a surface of the input device
forming a base surface or situated in parallel with this.
[0043] In one preferred embodiment, the input device is designed as
a) a wireline and/or b) a wireless remote control. In one
particularly preferred embodiment, the input device is a wireless
remote control, which creates the possibility of the operator
moving basically freely with the input device, without having to
worry about a cable which is connected by the input device to the
ground drilling device. A wireline remote control offers the
advantage of a substantially undisturbed transmission of signals by
the cable.
[0044] In one preferred embodiment, the input device is adapted to
use one or more radio bands for the communication with the control
device of the ground drilling device. In the sense of the
specification, a frequency band means frequency ranges, i.e.,
partial ranges of the electromagnetic spectrum of electromagnetic
waves used for technical communication. It is usual to partition
this spectrum by frequency, wavelength, or usage. Different
designations of frequency bands are possible, particularly
international ones.
[0045] In one preferred embodiment, the input device comprises one
or more antennas, in order to provide signal pathways, particularly
in a direction to heighten the operating safety of the ground
drilling device, for example. It may be provided that a
bidirectional transmission of signals is possible by means of an
antenna between the input device and the control device. But it may
also be provided that at least one antenna is provided for one
direction (from the input device to the control device and from the
control device to the input device) and different antennas are used
for the two directions. The antenna(s) may be connected to the
processor of the input device.
[0046] A bidirectional communication between the input device and
the control device is possible. For example, the control device may
confirm the entering of a parameter or relay to the input device
the fact that an error has occurred in the entering and/or
transmittal to the control device.
[0047] In one preferred embodiment, the ground drilling device
comprises one, two, or more antennas for the communication with the
input device. The ground drilling device can use in particular the
signal which is the strongest, the best, or the most stable, by
means of the control device.
[0048] In one preferred embodiment, the input device has a status
display to indicate a state. The status display may be connected to
the processor. The status display may involve a state regarding a
power supply of the input device, a transmission of data and/or
signals from the input device to the control device, a signal
strength, an indication that the input device has been switched on
or off, and/or an error message. The status display may be reduced
to the essential information, so that for example a display only
occurs when a particular state is reached--such as a critical one.
For example, the status display may be adapted to identify a
reduced power supply or a power supply of the input device tending
to decline in the near future. Alternatively or additionally, it
may be provided that the status display indicates that an error has
occurred during the transmittal of data from the input device to
the control device. Alternatively or additionally, the status
display can indicate that the signals generated by an activating
element are defective. Alternatively or additionally, the status
display can indicate that an error has been found at the ground
drilling device or the control device, particularly one in the form
of a signal of a device monitoring a critical state. The status
display may be a clear text display, a simple lighting means,
particularly a LED, which may be colored. In the case of a simple
lighting means, the color of the lighting means may correspond to
the state being displayed to the operator. For example, the color
may change or a different colored lighting means may be actuated or
become lit if the type of condition or the condition changes. For
example, it may be provided that, when the ground drilling device
is in operation and no error has been detected, a green light is
used. If the condition changes in the way of a worsening, for
example the power supply has been reduced below a certain degree in
terms of its capacity, the color orange may be used. A further
reduction or an error may be signaled with the color red. In the
area of the status display or as part of the status display, a
symbol may be situated or represented, particularly in the form of
an imprint, providing information about the status display. For
example, a battery symbol may be used for the status display
regarding a power supply. An antenna symbol may be used for a
status display regarding a transmission error.
[0049] In one preferred embodiment, at least one protective shield
for at least one mechanically operated activating element is
present, the extension of the protective shield transversely to the
surface on which the activating element is arranged being equal to
or greater than the extension of the element of a control stick. In
this way, an unintentional operation of the activating element can
be prevented, and a relatively simple mechanical construction will
be sufficient. Thanks to the protective shield, for example, it can
be prevented that an input device which is dropped and makes
contact with the ground does not operate the activating element due
to the effect of the ground surface. The protective shield in
addition to the mentioned spatial extension may also be arranged
relative to the mechanically operated activating element such that
an unintentional operation is largely precluded. It may be
preferable for the protective shield to be arranged in spatial
proximity to the mechanically operated activating element. The
protective shield may extend in multiple directions around the
mechanically operated activating element. The protective shield may
be present between an outer edge of the input device and the
mechanically operated activating element. The protective shield may
be interrupted at least partially or be closed, forming a wall
between the edge of the input device and the mechanically operated
activating element. The wall may extend in two directions with
respect to two different edges of the input device. More than two
walls are also possible, which may encircle or surround the
mechanically operated activating element at least for a portion, as
long as the operator continues to have a mechanical access.
[0050] In one preferred embodiment, the input device has a
mechanically firm structure which is adapted to the portion of the
human body of an operator, particularly a finger of an operator. In
this way, an input device can be created which conforms to
occupational medicine, user friendly, and/or personal body
criteria, in particular making possible a holding with no fatiguing
tension in the hands.
[0051] In one preferred embodiment, the input device has an
attachment for a carrying strap of an operator, so that the
operator is relieved of holding the weight of the input device.
More comfortable working is possible, more free of fatigue. It may
also be provided that the attachment by means of a carrying strap
can be used to carry the input device. The operator can let go of
the input device and the input device will still be attached to the
operator, for example, on a carrying strap fashioned as a shoulder,
neck, or waist strap.
[0052] In one preferred embodiment, the input device comprises an
element of a connection pair, which can interact mechanically
and/or electrically with a further element of the connection pair
which is situated at the ground drilling device. The connection
pair may be a pair of elements forming a mechanical and/or
electrical connection. The input device can be held securely on the
ground drilling device by means of the mechanical connection. By
means of an electrical connection, for example, a signal
transmission and/or a power transmission is possible. A charging of
the battery or the power supply of the input device is possible.
The further element of the connection pair may be present in
particular at the driver's station at the ground drilling device.
By means of the further element of the connection pair at the
driver's station, it is possible to use the input device at a fixed
position of the ground drilling device, with which the operator is
familiar, and where the operator is basically protected against
environmental factors.
[0053] In one preferred embodiment, the ground drilling device
comprises a control stick which is larger than a control stick on
the input device. In this way, the previous data entry possibility
through a familiar multifunction joystick can be preserved by means
of the control stick for the operator. In particular, the operator
will find at the driver's station the previously customary control
stick--being larger than the input device. The ground drilling
device can be operated at the driver's station in the otherwise
customary manner.
[0054] In one preferred embodiment, an indicator device is provided
for displaying at least one parameter for the operation of the
ground drilling device, the indicator device being adapted such
that it can optionally be mechanically connected to the input
device and/or the indicator device can be mechanically connected by
a coupling to the ground drilling device. On the one hand, it is
thus possible for the indicator device to form with the input
device a unit which can be manipulated in common and can be held by
an operator. On the other hand, it is thus possible for the
indicator device to be connected to the ground drilling device and
for the input device in turn to be connected to the indicator
device, whereby the input device can be indirectly connected
mechanically to the ground drilling device. By means of the
indicator device, the operation of the ground drilling device can
be visualized. The indicator device in particular can be an
electrical or electronic display, designed in particular as a
liquid crystal display (LCD), a light-emitting diode (LED) matrix
display, a fluorescent display (VFD) or the like. In particular, a
pictorial representation can be possible with the indicator device,
particularly one which is intuitively comprehensible. The indicator
device may be designed as a universal display instrument in the
form of a screen, a monitor, a display, a tablet, a notepad, and
IPAD, a SmartPhone or smart display. Thus, in addition to the input
device, a visualization of the operation of the ground drilling
device in regard to at least one parameter is possible by means of
the indicator device, which the operator can carry along with
him.
[0055] In one preferred embodiment, all of the aforementioned
parameters for the operation of the ground drilling device can be
called up and/or represented by means of the indicator device. The
display can be configured so that not all parameters are displayed
at the same time, but instead depending on the data entered by the
operator one or more parameters may be displayed, which the
operator can select for the display or which are deemed to be
important and/or essential by a command sequence of the control
device for the implementing and/or entering of a parameter. Thus,
the indicator device can be coupled to the input device in such a
way that--when the operator would like to enter a parameter by
means of the input device--the parameters, data, information and/or
prompts relating to this parameter are represented on the indicator
device. The coupling can be by way of a direct communication of the
indicator device and the input device or by way of an indirect
communication of the indicator device and the input device, for
example via the control device.
[0056] In one preferred embodiment, the input device has an inner
contour which is adapted to the outer contour of the indicator
device, and the input device surrounds the indicator device at
least partly along a section of the outer contour of the indicator
device. In this way, a connection can be created between the input
device and the indicator device whereby the indicator device is at
least partly surrounded by the input device. The indicator device
may be provided inside the input device, where the term "inside"
also encompasses the case where the input device does not entirely
enclose the indicator device. A substantially central arrangement
of the input device around the indicator device is possible. In
particular, the input device may contact the indicator device on
one, two, three or four sides. A form fit and/or a frictional
locking can be formed between the indicator device and the input
device. In particular, the form fit--as well as the friction
locking--may be optionally released in order to separate the
mechanical connection.
[0057] In one preferred embodiment, the indicator device is a
tablet, an Ipad, a notepad or the like, by which an especially
simple configuration is possible. The indicator device can make use
of a display element basically known in the prior art. The
aforementioned display possibilities are known and their use is
commonplace to an operator. The aforementioned possibilities for
the configuration of the indicator device can make possible an
intuitive use of the indicator device.
[0058] In one preferred embodiment, the indicator device comprises
a control unit which is adapted for a context-sensitive display of
information on the indicator device. For example, a value of
parameters for the operation of the ground drilling device,
information in connection with the parameter, and/or prompts for
the setting can be represented by means of the control unit if it
is important to the operator and/or if the operator would like to
enter or alter such a parameter. For example, if the operator
performs an entry of a parameter with the input device, the control
unit can represent the parameter influenced or altered by the
operator, even during the changing or the entry. It is possible,
for example, to continuously decrease or increase a parameter by
means of the input device, the value of which is represented on the
indicator device. It is also possible for the control device to
communicate with the control unit in order to represent
information, a value for a parameter, prompts and/or error
messages. For example, the control device of the ground drilling
device can tell the control unit of the indicator device when a rod
section needs to be connected to the introduced drill string in
order to move the earth borehole further onward. Moreover, states
of the ground drilling device can be represented that require
action by the operator.
[0059] In one preferred embodiment, the indicator device and the
input device are functionally connected such that when data is
entered on the input device the entry is displayed by means of the
indicator device. The input device may relay a signal to the
indicator device directly or indirectly via the control device of
the ground drilling device, telling it which parameter needs to be
altered or entered with the ground drilling device so that the
indicator device indicates the current value of the parameter
and/or parameters connected with the parameter.
[0060] In one preferred embodiment, the indicator device comprises
an entry area which is adjacent to the input device when the input
device and the indicator device are connected to each other. This
can create the possibility of a further data entry by the operator
existing on the indicator device, in addition to the possible entry
by the input device. In particular, the data entry at the indicator
device may involve a data entry with which the information being
displayed, which is shown on the indicator device, can be changed.
In particular, the type of the representation can be altered. A
retrieval of information regarding the ground drilling device is
possible. Furthermore, the entry area provided on the indicator
device makes possible a clear separation of the data entries which
can be performed by the operator. For example, the data entries for
changing the information being displayed must not be done on the
input device; the input device may be restricted to the entry of
the necessary parameters for the operation of the ground drilling
device. The entry option by means of the entry on the indicator
device can be done by means of a known touch-sensitive display from
the prior art. Preferably, at least one mechanically operated
activating element is configured adjacent to the indicator
device.
[0061] The indicator device can make possible an entry of
parameters, functions, and/or change of the representation on or at
the indicator device which may occur--insofar as the indicator
device has a touch-sensitive display--as so-called touch, type,
swiping of the display, or other similar entry. But it is also
possible alternatively or additionally for entries to be possible
on the indicator device by means of an integrated device or an
additional coupled device (such as by means of a cable connection
and/or wireless, such as Bluetooth). The integrated or additional
device may be a mechanically operated activating element (such as a
pushbutton, a rocker switch), a keyboard, a mouse, a track ball, a
graphics tablet, a microphone, a camera or a similar data entry
device, particularly one in the form of peripherals known in the
domain of computers, with which keyed entries or written entries,
audio entries (voice entry) and/or video entries (gestures, motion
or the like) are possible.
[0062] In one preferred embodiment, the indicator device is
connected to the control device of the ground drilling device in a)
wireless or b) wireline manner. In this way, a certain mobility of
the indicator device is possible. In the case of a wireless
connection, the mobility of the indicator device is increased in
regard to the free movements of an operator.
[0063] In one preferred embodiment, the indicator device is adapted
for a wireless data exchange by means of WLAN. A data protocol or
transfer protocol can be used for this, such as is known and easy
to handle. In particular, the data exchange or the functional
coupling between the indicator device and the control device of the
ground drilling device may be separate from a data exchange or the
functional coupling between the input device and the control device
of the ground drilling device. For example, less security may be
chosen in the communication for an exchange of data between the
indicator device and the control device of the ground drilling
device.
[0064] In one preferred embodiment, one or more antennas are
arranged on the ground drilling device for the communication with
the indicator device. The use of two antennas in particular on the
ground drilling device affords the possibility that the signal of
the control device of the ground drilling device which is the best,
most stable, or strongest signal on the particular antenna can be
used each time. When using multiple antennas, interference can be
minimized or even precluded. In one preferred embodiment, an
antenna may be present at the indicator device, particularly an
integrated one. In order to boost the range, in one preferred
embodiment a further or additional antenna can be screwed onto the
indicator device. The possibility of a boosted range is
particularly attractive when the operator is located very far from
the ground drilling device along the drilling route. It may also be
provided to have multiple antennas on the indicator device, each
time picking off a signal from them which is the best, most stable,
or strongest.
[0065] In one preferred embodiment, the input device and the
indicator device have separate power supplies. This makes possible
a greater flexibility. The power supply of the individual devices
can be smaller in dimension than a power supply for the common
power supply of input device and indicator device. Furthermore, the
power supply of a customary indicator device can be used.
[0066] In one preferred embodiment, the indicator device comprises
means of communication for the transfer of data and/or signals
between the indicator device and a locating system for the drilling
head. In this way, besides the parameters or information
represented on the indicator device for the operation of the ground
drilling device, it can also be shown on the indicator device where
in three-dimensional space the drill head of the drill string has
been detected by the locating system. In this way, the control unit
can be designed to process and evaluate the signals of a locating
system so as to indicate the current or detected location of the
drilling head. This indication can be done in various ways. A
pictorial representation on a map, particularly a selectable map,
which can be two-dimensional or three-dimensional, is possible. It
may be provided that the locating system does not directly relay
the data to the indicator device, but instead relays the data to a
gateway, which gathers in particular all the data--not just the
locating data--but also the operational data and the drilling data
that are recorded. The gateway, in turn, may send the locating data
and also other data gathered to a cloud. From the cloud, the data
may be downloaded, evaluated, and relayed. The indicator device is
designed to evaluate the data. Insofar as it has been said that the
indicator device comprises means of communication for the
transmittal of data and/or signals between the indicator device and
a locating system, this also means that the indicator device can
retrieve and/or evaluate this data, for example by means of a
downloading from the cloud. Alternatively or additionally, it is
possible for the locating data to also be sent and used directly by
the gateway--without a cloud being involved--or also directly from
the locating system to the indicator device.
[0067] In one preferred embodiment, the indicator device has a data
output which is provided in particular for putting out a record of
the operation of the ground drilling device, particularly a record
of the locating system in predetermined time intervals or a
continuously detected location of the drilling head. In this way,
an automatically created record can be put out at the data output,
which can be archived for calculation purposes, documentation of
the drilling, or the like. Moreover, the data output can be used
for other possibilities.
[0068] In one preferred embodiment, a detection device is provided,
which is adapted to detecting the drill string at its end side (a)
in the area of the ground drilling device and/or (b) in the area of
a target pit of an earth borehole being created, and the detection
device comprises transmission means which are designed to send
signals to the indicator device and/or to the control device,
wherein the indicator device and/or the control device are designed
to process the signals of the detection device such that the
signals are presented on the indicator device for a user. In this
way, an area can be detected where usually a (further) operator is
assigned to monitor the operation of the ground drilling device.
The operator who is controlling the operation of the ground
drilling device by means of the input device is shown information
thanks to the detection and the presentation of the detection on
the indicator device. In this way, the operator who is controlling
the operation of the ground drilling device by means of the input
device can be shown the corresponding end region of the drill
string in terms of the corresponding detection regardless of the
position of the operator. It can be provided that it is not
necessary for the operator to be present in the corresponding end
region of the drill string itself. The signal of the detection
device can be utilized. A further added value can thus be achieved,
since an additional operator to perform the earth drilling is
unnecessary and they may be given other tasks.
[0069] A "detection device" in the sense of the specification
encompasses any device which is designed to detect the presence of
a drill string, particularly an end of a drill string or a rod
section or a drilling head in an area. The detection device may be
designed as a device which ascertains a change in the presence of
the end of a drill string or a rod section or a drilling head.
[0070] In one preferred embodiment, the detection device is a
camera, a zone scanner and/or a motion scanner, whereby it is
possible to use known devices whose handling and use--albeit for
other fields--are customary.
[0071] In the sense of the specification, a camera is any device
which takes a picture of an area that can be displayed in
particular on the indicator device. The indicator device can
display the signals or information of the camera at least on a
portion of the indicator device for this. The signals may be
represented directly or be processed prior to the presentation by
the control unit of the indicator device and/or the control device
of the ground drilling device.
[0072] In the sense of the specification, a zone scanner is a
device which can ascertain and detect a change in a presence in a
zone. The zone scanner may be designed as a light barrier, light
curtain, or the like. The zone scanner may be designed to use
ultrasound, electromagnetic radiation in the infrared region, or
radar waves.
[0073] In the sense of the specification, a motion scanner is a
device which can ascertain and detect a movement in a zone.
[0074] Both the zone scanner and the motion scanner may be used in
such a way that, when a movement in any form has been detected, a
message is sent to the indicator device. It may also be provided
that a signal of a zone scanner or motion scanner is relayed to the
input device and a triggering of the zone scanner and/or motion
scanner is indicated on a status display of the input device. It
may also be provided that as soon as the zone scanner and/or motion
scanner is triggered, a picture of a camera is presented on the
indicator device, so that the displaying of a picture of a camera
which may be present is done only if the zone scanner and/or motion
scanner have ascertained a change or a presence of an end of the
drill string or rod section or the drilling head.
[0075] The invention also creates a method for controlling the
operation of a ground drilling device. The method involves the step
of entering at least one parameter for the operation of the ground
drilling device. The parameter may be in particular a parameter
bringing about a starting of the drilling with the ground drilling
device or a stopping of the drilling performed with the ground
drilling device. In the method, the entering of the at least one
parameter is done by means of a remote control.
[0076] The invention also creates a use of a ground drilling
device, having a control device for the operating of the ground
drilling device. An input device functionally coupled to the
control device is used for entering at least one parameter for the
operation of the ground drilling device. The at least one parameter
may be in particular a parameter bringing about a starting of the
drilling with the ground drilling device or a stopping of the
drilling performed with the ground drilling device. A remote
control is used as the input device.
[0077] The invention is being described in regard to three aspects,
relating to a system, a method, and a use. The remarks on the
individual aspects complement each other, so that the remarks for
the system should also be understood as remarks describing the
method and the use. With the description of the system, actions in
regard to the method or method steps concerning the method and uses
or usage features are also disclosed, applicable to the
corresponding aspects.
[0078] In the sense of the specification, the indication of a
numerical value, particularly a length or an angle, encompasses not
only the actual numerical value, but also a range about the
specific numerical value which may be +/-15%, preferably +/-10%, of
the indicated numerical value--in order to allow for fabrication
tolerances, in particular.
[0079] The preceding remarks, just as the following description of
exemplary embodiments, do not constitute any abandonment of
particular embodiments or features.

DETAILED DESCRIPTION
[0090] FIG. 1 shows in a schematic representation a ground drilling
device 1 with which an earth borehole can be made in the soil. Rod
sections are stored in a string magazine 2, with which the drill
string 3 already introduced into the soil can be lengthened.
[0091] The ground drilling device 1 comprises a control device 4
for operating the ground drilling device 1, being shown
schematically by means of the box in broken lines. The operation of
the ground drilling device 1 can be controlled by means of the
control device 4.
[0092] Moreover, there is present an input device 5, functionally
coupled to the control device 4, being adapted to enter at least
one parameter for the operation of the ground drilling device 1. In
particular, such a parameter may be a starting of the drilling with
the ground drilling device 1 or a stopping of a drilling performed
with the ground drilling device 1. The input device 5 is configured
as a remote control, which communicates in wireless manner with the
control device 4 by means of electromagnetic waves.
[0093] The wireless communication between the input device 5 and
the control device 4 is a bidirectional communication, in which the
input device 5 both receives signals from the control device 4 and
sends to the control device 4. The bidirectional wireless
communication is indicated by means of the double arrow ES.
[0094] Moreover, an indicator device 6 is provided, with which
information and/or parameters for the operation of the ground
drilling device 1 can be represented. For the representation of the
information and parameters, the indicator device 6 is functionally
coupled to the control device 4. The communication between the
indicator device 6 and the control device 4 is wireless by means of
electromagnetic waves. The communication is bidirectional, so that
the indicator device 6 can both receive signals from the control
device 4 and send to the control device 4. The bidirectional
communication is indicated by means of the double arrow AS.
[0095] As can be seen from FIG. 2, the indicator device 6 can be
arranged in a holder 7 of the input device 5 so that the indicator
device 6 can be manipulated together with the input device 5 as a
unit by an operator.
[0096] The input device 5 comprises multiple mechanically operated
activating elements 8, two of which are configured as control
sticks. Moreover, the input device 5 comprises an emergency off
switch 9 as a mechanically operated activating element 8, being
configured as a pushbutton. The activating elements 8 configured as
control sticks and the emergency off switch 9 are facing toward an
operator when the input device 5 is held and are located in a plane
of the input device 5. Situated opposite the surface on which the
control sticks and the emergency off switch 9 are arranged, two
rotary switches are formed as mechanically operated activating
elements 8 at the left and right of the input device 5.
[0097] On the left side of the input device 5 there are provided
multiple status displays 10 providing information as to the status
of the input device 5, the ground drilling device 1 and/or a
communication between the input device 5 and the control device
4.
[0098] Moreover, the input device 5 has a receiving space 11 for a
power supply of the input device 5, designed as a compartment on
the underside of the input device 5.
[0099] A swiveling antenna 12 is present for the wireless
communication with the control device 4, which can swivel in regard
to its orientation and is telescopically adjustable in length.
[0100] A protective shield 18 is formed on the input device 5 to
protect the activation of the mechanically operated activating
elements 8, being situated in the area of the emergency off switch
9 and the control stick.
[0101] Connection elements 13 are provided for the attachment of a
neck, shoulder, or waist strap, to which the corresponding strap
can be connected.
[0102] The input device 5 comprises a base plate 14 to hold the
indicator device 6, being substantially rectangular in shape (see
FIG. 1). The mechanically operated activating elements 8 are formed
in handle-shaped protrusions 15 of the base plate 14, each of them
being graspable by the hand of the operator in order to carry out
the operation. The protrusions 15 extend in an upward direction,
and form an edge around the base plate 14. The protrusions 15 each
form an edge on one side. The two edges which are formed by the
protrusions 15 lie opposite each other. On the other two sides of
the rectangular base plate 14 there are other marginal segments
extending upward in the same direction as the edges formed by the
protrusions 15. In this way, an edge is created which surrounds the
base plate 14 at least partly, in which the indicator device 6 can
be arranged. A force locking can be formed, with the indicator
device 6 engaging at least partly behind the protrusions 15 at the
edges formed by the protrusions 15.
[0103] FIG. 5 to 7 show another embodiment of the input device 5
with the indicator device 6 of FIGS. 2 to 4. The protrusions 15 of
the input device 5 in this case are not designed as handles which
can be grasped by hand. The representations at left and right of
FIGS. 5 to 7 show the area of the protrusions 15 from the side.
There are present a control stick at the top, a forward pointing
rotary switch, and two pushbuttons as the mechanically operated
activating elements 8 for each protrusion 15.
[0104] FIG. 8 shows a system with a detection device 16 designed as
a camera, being adapted to detect the drill string 3 at its end in
the area of a target pit 17 for an earth borehole being produced.
The detection device 16 comprises transmission means which are
adapted to send signals to the indicator device 6 and to the
control device 4. The signals can be represented on the indicator
device 6, in particular, a picture taken by the camera can be
represented on the indicator device 6.
