[0036] The embodiments and examples discussed herein are
non-limiting examples.
Detailed Description of the Non-Limiting Exemplary Embodiments of
the Figures
[0037] Reference is made herein to exemplary embodiments shown in
the figures, however, these references non-limiting examples of
exemplary embodiments and should not be construed to limit this
disclosure. With respect to the figures, similar reference numerals
indicate similar components.
[0038] FIGS. 1A and 1B show an exploded view and an overview
respectively of an exemplary embodiment of the instant invention.
The exemplary embodiment can be utilized in any application for
which it might be suited. One non-limiting example of an
application is the use of the electronically controlled valve
actuator in a water condition management, conditioning or treatment
system, specifically in a chlorination system like that shown in
applicant's co-pending application 60/778,392, filed Mar. 3, 2006
and incorporated herein by reference.
[0039] In such an installation, the system would be installed in
the plumbed line at the point of, for instance, a two or three way
valve 205 for redirecting water flow to a brine distribution
system. The exemplary embodiment is mounted by removing any
existing hardware on the stem of the existing valve. The shaft 150
has a hollow end 151 with splines (not shown) that match the
existing splines on the valve shaft 202. Once seated on the valve
shaft, the electronically controlled valve actuator is provided a
power source 30, for instance through a typical plug or batteries.
In the exemplary embodiment, a 120V AC power supply line is
provided. In addition to the power supply, the actuator can provide
for a communications input/output line 32 for relaying information
to a master controller or a wireless communication device or
wireless link 33 may be provided to similarly communicate data from
the instant invention wirelessly. In an exemplary embodiment, this
communication with outside controllers can be for instance provided
via an RS 485 communication standard. Similarly, external devices
can be coupled through the communications input/output line 32, for
instance, a user input device, or an alternative port may be
provided. Additionally, if the controller is located on the
actuator, the communication output line 32 can also act as an input
line for data from sensors.
[0040] The instant invention, as shown in the exemplary embodiment,
includes an electronic motor 100 that drives a transmission device
175 that drives shaft 150 that is coupled to the valve as described
above. The shaft 150 is turned by motor 100 and an at least one
shaft encoder device 210, as part of the actuator controller 200,
reads the motion and position of the shaft 150 feeding output to
the actuator controller 200. The exemplary embodiment seals the
motor 100 and electronics, including the actuator controller 200,
in a housing 1. The housing 1, in the exemplary embodiment shown,
includes an upper housing section 10, a lower housing section 5,
and a chassis section 7. The housing 1, with its component parts,
seals the electronics and motors in a watertight compartment,
preventing intrusion of water.
[0041] The actuator controller 200 can include, for example, an at
least one printed circuit board 220 and a controller IC 230,
coupled to the at least one shaft encoder device 210 and
controlling the position of the shaft, turning the shaft, and
reporting this position via a graphical user interface 300. The
actuator controller 200 has direct control over the position and
operation of the electronic motor 100 and thereby the valve.
Alternatively, the controller 200 can be slaved to an external or
master controller 2000, which may be integral or external to the
actuator, to control the function of the actuator in conjunction
with a larger system controlling the water treatment, management,
or conditioning system 10 as shown. In the exemplary embodiment,
the on-board controller 200 can be programmed to provide a wide
array of controllable positions based on either input from a master
controller 2000 or manual input. In further exemplary embodiments,
the actuator controller 200 can be the master controller and
control the actuator based on data inputs from outside the actuator
like controller input 39 shown in FIG. 1B in relation to master
controller 2000.
[0042] In the exemplary embodiment shown, multiple programmable set
points can be pre-programmed into the actuator controller 200. The
controller 200 can be retrofit to replace existing manual and
analog controlled valves having a splined valve stem or to
integrate with an existing controller through the data
communications provided. The motor 150 can be driven to turn the
valve in either the clockwise or counterclockwise direction. Set
points are pre-programmed on the actuator controller 200.
Additionally, the set points can be changed through manual
operation and programming of the actuator and actuator controller
200 as further explained below.
[0043] The actuator controller 200 of the exemplary embodiment
shown responds to an outside master controller 2000 external to the
housing coupled through the communications input/output line 32 or
a wireless link 33. The master controller 2000 in this embodiment
processes data inputs from sensors or controller inputs 39 and the
controller actuator 200 is moved based on these inputs. In a
further embodiment, sensors and sensor inputs transmit data
directly to the actuator controller 200 as master controller and
the actuator controller 200 changes position and control the water
condition management system 10. The sensors and the data inputs
from the sensors 39 can be for example, but are not limited to,
pressure switches, flow switches or similar condition indicators
and the data outputs can include, but are not limited to,
temperature, ph, salinity, pressure, overall chemical makeup, flow
speed, rates of change in these conditions, and similar data
regarding the water or components of or within the water condition
management system. Thus the actuator of the instant invention can
automatically respond to changes in and/or control fluid flow,
pressures, and other conditions within the water condition
management system as a part of the system or as the master
controller in the system.
[0044] The digital control capability allows the instant invention
the ability to set the stop points or set points corresponding to
specific operating positions of the actuator without removing any
part of the housing 1, as required in the conventional analog
controlled devices currently available. Thus, a greater number of
operating points can be provided for and customized with minimal
disruption to the water condition management system 10.
[0045] Thus, the actuator controller 200 can be adjusted in the
field to respond to specific sensor input criteria, thresholds, or
outputs 39 in conjunction with a master controller 2000 or acting
as the master controller and, thereby, respond automatically to
change the condition of the valve by programming through its
communications input/output line 32, a 5 pin programming port, or
through instructions from the master controller controlling the
entire Water Condition Management System 10 that can be programmed
to respond to specific sensor input criteria, thresholds, or
outputs 39 and operate the actuator. Thus, the actuator can be
utilized in a wide variety of water management systems. The
programming can be pushed onto the master or the actuator
controller through a portable computing device, through a wired
connection, through a network, wirelessly, or through a similar
method through a wired or wireless connection.
[0046] FIG. 2 shows a cross-section of an exemplary embodiment of
the instant invention. The shaft 150 is clearly shown with the
hollow, splined end 151 that fits over the valve stem (not shown).
The motor 100 is sealed in the chassis 7 by the combination of the
upper housing 5 and lower housing 10. Interspersed at critical
points is an at least one sealing body member or device 160 to
prevent intrusion of water into the housing 1. The shaft encoder
210 is provided on the shaft 150 and in communication with the
controller 200. The controller 200 is in communication with an at
least one indicator element 390 and user inputs 330, which comprise
a graphical user interface 300.
[0047] FIG. 3 shows top down view of an exemplary embodiment of a
user interface of the instant invention. The user interface 300, in
the exemplary embodiment shown, includes an at least one indicator
element 390, in this case a series of Light Emitting Diodes (LEDs)
340 for graphically displaying to a user the state of the valve and
its current position. The exemplary embodiment, marketed as the
INTELLIVALVE, is a digital actuator and controller unit The
position of the valve is indicated by the at least one graphical
indicator 390, here 24 green LEDs 340 that circle the top of the
actuator. Each LED indicates a 15-degree incremental movement of
the valve. Although in the exemplary embodiment of the invention,
the actuator turns in 15-degree movements, greater or lesser
incremental movements can be provided for and are within the scope
of the invention.
[0048] In the exemplary embodiment, if the actuator is between the
15-degree positions, the respective LEDs preceding and following
the current position blink to indicate the position of the
actuator. There are also at least two LED's in the middle of the
display dial in the exemplary embodiment. In this case, two LEDs
are provided, one of these being an Amber LED 346 and the other
being a Red LED 345. In the exemplary embodiment, these indicate
the set movement position of the actuator either in the Clockwise
direction (amber) 346 or Counterclockwise (red) 345. The movement
is controlled by either the controller 200 or the user, depending
on whether the actuator is in automatic or manual mode. A further
indicator element, again a set of inputs 332, 338 and LEDs 333,339
as described herein below, indicates whether the device is in the
automatic or manual mode and sets the set points.
[0049] The automatic operation of the actuator utilizes set points
for controlled operation in any number of operating positions based
on sensed parameters or conditions. The customized set points are
programmed in a set mode, operated between in a manual mode, or set
to operate automatically in an auto mode. The exemplary embodiment
of the instant invention, for instance, is pre-set for a 180
degree, two-way operation automatically. If after installing the
actuator the 180-degree rotation is correct but is opposite of the
plumbing setup, the direction can be reversed. Most installations
will probably not require adjusting the valve actuator, however, if
a change in the rotation of the valve is required a customized set
point or set points can be established in the set mode.
[0050] In the automatic mode the movement of the actuator and
thereby the rotation of the valve is controlled by the controller
200. The controller 200 can be integral with the actuator, as
depicted, or external to the actuator, as mentioned previously. The
controller 200 receives data inputs from an at least one sensor, as
previously discussed. In the exemplary embodiment the actuator is
used in the Salt Dispensing System (SDS), which is described in
co-pending application 60/778,392, filed Mar. 3, 2006 and
incorporated herein by reference. Based on these inputs the
programmed logic or software on the controller 200 decides the
position of the actuator. The system automatically moves to the set
point position as directed by the controller 200 based on the
sensor input received and the software.
[0051] In the exemplary embodiment, in the GUI 300 the set points
of the actuator will remain lit, but the actual arc the valve will
turn in will only light the LEDs when actuator is activated and
will remain lit approximately one minute after the actuator
finishes turning. Additional indicator patterns can be included to
indicate, for example, emergency valve shutoff or to warn if a set
position is exceeded while being manually operated or to indicate
other operational scenarios. Additional indicators can also be
provided, for instance, to indicate when the controller is
communicating with external controllers and/or sensors, the
operating mode of the actuator (e.g. automatic, manual, setting,
programming, etc.), or any additional conditions that would be
practical.
[0052] In setting customized set points, the set mode is entered.
This may be accomplished through a further user input device or
through a combination of existing user input devices. In the
exemplary embodiment, this is accomplished in the exemplary
embodiment by pressing and holding the auto/manual mode button 338
for a period of time. In this instance, the Auto/Manual LED will
turn red 339. The user then uses the appropriate clockwise or
counterclockwise button 334, 336 until the valve actuator display
shows the desired stop point. The user then inputs the direction
the actuator is to turn. This may be accomplished by any
combination of existing or additional user inputs. In the exemplary
embodiment, if it is clockwise, the set mode button 332 is pressed
and released until the amber LED 333 is lit. By pressing and
holding the Set Mode button 332, with the amber LED 333 lit for
approximately two seconds or until the amber lights 346, 335, 337
on both the display 346 and the respective
clockwise/counterclockwise buttons 334, 336 illuminate, the custom
set point is input. Next the actuator can be moved by pressing the
appropriate directional buttons 334, 336 to establish a second
customized stop or set point or the user can end input by
depressing the necessary user inputs. In the exemplary embodiment
this is accomplished by pressing and holding the Auto/Manual button
338 once again to go back to Auto mode indicated by LED 339 turning
green and the system is set and ready for automated operation
between the customized set of stop points.
[0053] If the custom set points or the default programmed set
points are correct, but they are operating exactly opposite of what
is desired, in the Set Mode of the exemplary embodiment the user
holds the clockwise 334 and counterclockwise 336 buttons down
simultaneously for two seconds. The LED's in the center 345, 346
will blink and the actuator will now operate in a reverse mode.
Similarly, if a user desires to reset the default stop positions,
the user input can be operated to do so.
[0054] The actuator can also be operated in a manual mode. By
depressing the Auto/Manual mode button 338 manual mode can be
entered. The actuator is operated manually through an at least one
user interface 330, in the exemplary embodiment it is shown as a
set of buttons for clockwise movement 334 or counterclockwise
movement 336. In this mode, the operator selects the open setting
of the valve and receives output through the graphical interface.
When the user pushes this button the first time, the LED turns from
green to yellow and indicates the device is in manual mode by
changing LED 339 next to the auto/manual mode button 338. In manual
mode, the user can manually switch the valve from one position to
another. The valve only manually operates the actuator from one
position to the other, the controller is taken offline.
[0055] In this mode, in the exemplary embodiment the indictor LEDs
light from Amber to Red in an arc as the system is moved.
Additional or fewer indicator elements may be included and the
pattern changed to show the turning of the instant invention
without departing from the spirit of the invention. The current
position of the valve is indicated by a blinking LED light. In the
exemplary embodiment shown, the center position LED, indicating
direction of traverse, is Amber or Red when current position is on
Amber (clockwise) or Red (counterclockwise). The two buttons,
clockwise and counter clockwise will operate in manual mode.
Selecting the clockwise button (Amber) the actuator will move the
Amber or counterclockwise position. Selecting the counterclockwise
button, the actuator will move to the Red or clockwise set
point.
[0056] A "safe area" or "safe zone" is programmed into the arc of
the controller based on the position of the valve relative to the
input line. This feature would help prevent accidental overpressure
situation. In the exemplary embodiment, for instance, if the
position of the actuator is moved more than 12 positions, (1/8 of
the led indicator dial) outside of the Amber or Red stop points,
the non-arc side of the circle of LEDs 340 will start to flash and
the SET button will flash red. The user will have to press the
Clockwise or Counterclockwise button 334, 336 for 2 seconds to
override the safety feature and continue moving outside the safe
area or arc. If the Clockwise and Counterclockwise button is not
pressed, the LEDs will return to normal in approximately 3 seconds
and the Clockwise and Counterclockwise buttons will be ignored. In
general, a valve, especially a two or three way valve, it is
undesirable to completely shut the input line. Once the user has
moved outside the safe area the unit will not warn the user again
until the user enters and leaves the safe area or zone again. The
degree and portion of the arc can be varied to suit the conditions
of the water condition management system.
[0057] In the exemplary embodiment, to return to Auto mode, the
user simply utilizes one of the user inputs. In the exemplary
embodiment, the user simply press and holds the user input that
changes the auto/manual mode 338 until the LED indicator element
339 turns green again. The Man/Auto button LED indicator element
339 is green for Auto mode. In this mode, the actuator will operate
based on a signal from the controller, as outlined above. All other
buttons will not respond while in this mode and the actuator will
be moved between the set points.
[0058] The invention is described in detail with respect to
preferred embodiments, and it will now be apparent from the
foregoing to those skilled in the art that changes and
modifications may be made without departing from the invention in
its broader aspects, and the invention, therefore, as defined in
the claims is intended to cover all such changes and modifications
as fall within the true spirit of the invention.
