Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a lighting control system
with a security function based on a CPTED (Crime Prevention Through
Environmental Design) and a method thereof, and more particularly,
to a lighting control system with a security function based on a
CPTED, which is capable of acquiring detailed video information on
a desired object in interlocking with a video device such as a DVR
based on sensing information collected through sensors included a
local lighting device and controlling a lighting adjacent to the
object to strengthen a security function.
[0003] 2. Description of the Related Art
[0004] At present, lamps including fluorescent lamps, incandescent
lamps, LEDs and the like are installed in different sites in
collective buildings and systems for managing a number of lightings
effectively are being settled in concert with recent energy saving
policies. Accordingly, a scheme of connecting a plurality of
lightings to a small number of lighting control servers via a
communication line and inputting a control command to the lighting
control servers to manage the plurality of lightings integrally
instead of directly controlling the individual lightings is being
used.
[0005] In recent years, such a lighting integrated management
system is not limited to a simple dimming control function for
energy saving, but advances have been made toward providing a more
efficient system by controlling lightings based on an event in
interlocking with a variety of systems.
[0006] As one example, there has been proposed a system in which a
lighting control server controls a lighting in response to sensing
of an object in interlocking with a DVR. In this system, when the
DVR provides a position at which the object is sensed by a camera
to the lighting control server, the lighting control server
performs dimming control for a lighting corresponding to the
position of the object in order to provide increased energy saving
efficiency.
[0007] Recently, this system is being extended to a system for
associating a separate video analysis module with the DVR. That is,
this system is a system in which, when the video analysis module
analyzes a video collected in the DVR and an event corresponding to
a preset event setting is generated, control information used to
control a lighting with a function corresponding to the event is
provided to the lighting control server and the lighting control
server controls the lighting according to the function
corresponding to the received control information.
[0008] Such a system configuration can make it possible to
implement a CPTED (Crime Prevention Through Environmental Design)
intended to prevent crimes through a built environment design being
recently considered in architectural designs while securing an
efficient lighting control function for energy saving. That is, it
is possible to provide a multi-purpose system capable of providing
an energy saving function and a crime prevention function by
controlling lightings in response to motion of a suspicious object
through video analysis in the system constructed in a building.
[0009] However, such a multi-purpose system requires increased
system construction costs due to an additional separate video
module. In addition, when this system is applied to a place where
lightings are installed, if a DVR operated separately from a
lighting control server is constructed, this leads to increased
unnecessary costs due to the additional DVR interlocking with the
lighting control server.
[0010] In addition, in case of a system for controlling lightings
based on videos collected from cameras, a shadow zone may take
happen since shooting locations of the cameras remain fixed. In
addition, since the number of cameras cannot be unlimitedly
increased, a video obtained in a particular zone may have a low
video quality or a shadow zone depending on camera arrangement and
locations and accordingly, a proper security function through the
lighting control does not work well.
[0011] To overcome these problems, there appears a system for
compensating for the shadow zone and the video quality through
control of operation of cameras responding to sensors by
simultaneous operation of the cameras and the sensors. However,
such a system requires a separate communication line for the
sensors and a separate module for analyzing sensing information and
controlling the cameras, which may result in increase in system
construction costs and low cost-effectiveness.

and acquire a high quality video for an object serving as the basis
of event generation.
[0020] The video unit may store the high quality video.
[0021] The lighting control unit may determine different events
depending on the type of the sensor and select one of control of a
lighting adjacent to the lighting generating the sensing
information, control of a lighting placed on a route from a
position of the lighting generating the sensing information to an
exit, and control of one or more adjacent lightings including light
control of adjacent lightings.
[0022] The lighting control unit may control the brightness of a

from other lightings.
[0023] The lighting control unit may return the brightness of the
entire lighting according to a preset initialization setting if the
sensing information is not received any longer and return the video

[0024] According to another aspect of the invention, there is
provided a method of controlling a lighting with a security
function based on a CPTED (Crime Prevention Through Environmental
Design), including: a first step in which a lighting control server
connected, via a control line for remote lighting control, to a

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0039] Hereinafter, a lighting control system with a security
function based on a CPTED according to an embodiment of the present
invention will be described in detail with reference to the
drawings.
[0040] FIG. 1 is a conceptual view of a lighting control system
with a security function based on a CPTED according to an
embodiment of the present invention. Referring to FIG. 1, the
lighting control system with a security function based on a CPTED
may include one or more lighting units 10, each including a dimmer
unit 11 for controlling dimming of a lighting and a sensor 12, a
lighting control unit (lighting control server) 100 for controlling
the lighting units 100 integrally, and one or more DVR units 200
which interlock with the lighting units 10 and receive and store a
video from one or more cameras 210.
[0041] The lighting control unit 100 may be directly connected to
one or more camera units 300 such as IP cameras supporting a
network, instead of the DVR units 200. Of course, the lighting
control unit 100 may be connected to general wired/wireless-enabled
cameras instead of the IP cameras.
[0042] In more detail, each dimmer unit 11 can control the
brightness of each lighting unit 10 autonomously based on sensing
information of the sensor 12 included in each lighting unit 10 in
interlocking with the sensor 12. In addition, the dimmer unit 11
may be connected to the lighting control unit 100 through a control
line to receive a dimming control signal from the lighting control
unit 100 and control the brightness of the lighting unit 10
according to the received dimming control signal.
[0043] In addition, the dimmer unit 11 can transmit the sensing
information of the sensor 12, along with a lighting ID, to the
lighting control unit 100 via the control line and the lighting
control unit 100 can compare the sensing information with a preset
value or a criterion and generate an event if the sensing
information meets with the preset value. This can eliminate a need
to construct a separate sensor-related line for facilitating an
application. In this case, the lighting control unit 100 can
identify the lighting unit 10 by collating the lighting ID with the
DB unit 150 (see FIG. 2) included in the lighting control unit
100.
[0044] When the event is generated, the lighting control unit 100
can generate event-related information corresponding to the sensing
information and directly transmit the event-related information to
the DVR unit 200 or the camera unit 300. The event-related
information may be upper level information on type, position,
status or the like of the event according to a preset protocol.
However, if a general-purpose DVR unit 200 or camera unit 300 is
used, an operation according to event contents may be provided as a
direct command to directly control the operation.
[0045] To this end, the lighting control unit 100 may store a
mapping table 151 (see FIG. 151) in the DB unit 150. The mapping
table 151. The mapping table 151 may include information on at
least one of the DVR unit 200 and the camera unit 300 matching the
lighting ID, and event-related information matching the sensing
information.
[0046] Here, the event-related information may include event's
generation criterion, type and position, environmental information
(time, setting, weather and the like), corresponding operation
contents (event transfer protocols, a series of commands for direct
control, etc.) and associated lighting information (associated
lighting IDs, dimming information, lighting type, lighting time,
etc.)
[0047] Accordingly, the lighting control unit 100 can match the
lighting ID and the sensing information with the mapping table 151
and extract channel information of the DVR unit 200 connected to
the camera 210 corresponding to the lighting ID or the camera unit
300 and an event corresponding to the sensing information.
Thereafter, the lighting control unit 100 can request or directly
control an operation according to the event-related information
based on the extracted channel information.
[0048] Accordingly, the DVR unit 200 or the camera unit 300 can
receive the event-related information or a command signal and
perform an operation corresponding to the event. As one example,
the DVR unit 200 can be connected to at least one camera 210 such
as a PTZ (Pan/Tilt/Zoom) camera, a dome camera or the like and
control the camera 210 corresponding to the lighting ID based on
the event-related information. In this case, cameras 210 and 300 of
the DVR unit 200 or the camera unit 300 operating according to
corresponding operation contents of the event-related information
are preferably cameras adjacent to a lighting transmitting the
sensing information.
[0049] In other words, the DVR unit 200 can acquire a high quality
video for an object from the camera 210 by controlling the camera
210 to face the object sensed by the sensor through a function such
as PTZ adjustment or resolution change of the camera 210 based on
the event-related information.
[0050] Similarly, the camera unit 300 can operate to acquire a high
quality video for the object facing the camera unit 300 through its
PTZ or resolution adjustment based on the received event-related
information.
[0051] In addition, The DVR unit 200 can transmit an alarm signal
to an established external device or system based on the
event-related information received according to an internal preset
operation scheme of the DVR unit 200 in order to alarm a system
manager or an external control center. Of course, this may be
directly carried out by the lighting control unit 100.
[0052] Further, the lighting control unit 100 can dim one or more
lightings associated with the lighting generating the sensing
information based on the event-related information in order to
increase illuminance for securing of a high quality video for an
object or for attraction of attention and route guidance according
to a security function.
[0053] In this manner, the lighting control unit 100 can acquire a
high quality video for an object such as a person or vehicle sensed
in a shadow zone by directly controlling cameras through the DVR
unit 200 and/or the camera unit 300.
[0054] Hereinafter, an embodiment of the above-mentioned units and
components will be described in more detail with reference to the
drawings based on the above-described configuration.
[0055] First, referring to FIG. 2, the lighting control unit 100
may include a communication unit 140 for communication with the DVR
unit 200 through a general-purpose protocol, an external power
receiving unit 110 for receiving external power to be provided to
the lighting unit 10, a power providing unit 120 for adjusting
power received from the external power receiving unit 110 and
providing the adjusted power to the lighting unit 10, an
input/output unit 130 connected to the dimmer unit 11 of the
lighting unit 10 via a control line and a power line, a DB unit 150
in which the mapping table 151 is stored, and a control unit 160
for controlling the above-mentioned units.
[0056] The lighting unit 10 may include the sensor unit 12, the
dimmer unit 11, and a lamp unit (not shown) operated by dimming
control of the dimmer unit 11.
[0057] An operation of each unit will now be described in more
detail based on the above-described configuration. First, the
sensor unit 12 of the lighting unit 10 can generate sensing
information according to sensing of an object and provided it to
the dimmer unit 11. The dimmer unit 11 can provide the sensing
information to the input/output unit 130 via the control line. The
control line is basically used to exchange a dimming signal and a
result with the dimmer unit 11. The control line can be further
used to collect the sensing information, thereby eliminating a need
to provide an additional line.
[0058] In addition, the control unit 160 can receive the sensing
information and a lighting ID through the input/output unit 130,
compare the sensing information, the lighting ID and environmental
information (time, setting, weather and the like) with a preset
event status, generate an event based on a result of the
comparison, and obtain information on the DVR unit 200 or the
camera unit 300 connected with a camera adjacent to the lighting
unit 10 corresponding to the lighting ID and corresponding
operation contents corresponding to the event.
[0059] As shown in FIG. 2, the DB unit 150 includes a lighting
storage unit 152 in which the lighting ID of the lighting unit 10
and position information for each lighting ID are stored, an
address storage unit 153 for the DVR unit or the camera unit
connected to the lighting control unit, and an event information
storage unit 154 storing the event generation criterion and a
corresponding operation. In the mapping table 151, information
stored in the lighting storage unit 152, information stored in the
address storage unit 152 and information stored in the event
information storage unit 154 are mutually matched so that proper
event determination and provision of the corresponding operation
contents can be promptly made. Of course, although the mapping
table 151 is shown to have a logical configuration, it is to be
understood that the mapping table 151 may be configured in
different forms and is intended to encompass various different
configurations.
[0060] As one example of the corresponding operation contents, as
shown in FIG. 3, the event-related information provided to the DVR
unit 200 may include one or more of adjustment information used to
adjust resolution or PTZ of a camera for each lighting ID,
connected to the DVR unit 200, information related to whether or
not to generate an alarm signal of the DVR unit 200, and associated
lighting information including one or more different lighting IDs
to be controlled in association with the lighting ID depending on
an event. In addition, in a case of directly controlling the DVR
unit 200 and/or the camera unit 300, corresponding operation
information may further include a series of commands for specific
correspondence.
[0061] The control unit 160 can extract the event-related
information through the mapping table 151 and provide this
information to the DVR unit 200 or can directly control the DVR
unit 200 or the camera unit 300 with a general-purpose control
signal. Accordingly, the lighting control unit 100 can be easily
connected to the DVR unit 200 and the camera unit 300 which are
established to operate independently of each other, and
accordingly, it is possible to cope with a dedicated DVR unit or a
general-purpose DVR unit or camera unit.
[0062] Accordingly, there is no need to install an additional
separate DVR unit 200 or camera unit 300 for interlocking with the
lighting control unit 100.
[0063] In particular, since different types of sensors can be
selectively applied for each lighting, it is possible to easily
realize prevention of dead zone, extension of usage, improvement of
reliability, etc.
[0064] The above-described configuration can implement a security
function in association with lighting, which will be described
below with reference to FIGS. 4 and 5 based on the configuration
shown in FIGS. 2 and 3.
[0065] First, as shown in FIGS. 4 and 5, the DVR unit 200 or the
camera unit 300 received a signal of the corresponding operation
contents according to the event can control a camera to face a
lighting unit 13 providing the sensing information or increase its
resolution according to the corresponding operation contents. That
is, the DVR unit 200 or the camera unit 300 can obtain a higher
quality video according to sensing of objects 400 and 500.
[0066] In addition, according to such event generation, the
lighting control unit 100 can brighten other lightings adjacent the
lighting unit 13 providing the sensing information in order to
provide sufficient lighting to the sensing object 400 while
increasing video photographing quality. As will be described later,
such adjacent lighting control can be adjusted in different ways,
such as brightening adjacent lightings in a sensing zone,
brightening lightings on a route to an exit or an elevator,
etc.
[0067] Accordingly, the DVR unit 200 or the camera unit 300 can
acquire high resolution or extended high quality videos for objects
from a camera, thereby easily distinguishing the objects 400 and
500 from each other and covering a shadow zone where the objects
400 and 500 may be located through PTZ or resolution adjustment of
the camera.
[0068] In addition, the DVR unit 200 or the camera unit 300 can
transmit an alarm signal to an established external device or
system based on the alarm signal generation-related information
included in the corresponding operation contents in order to alarm
a system manager or an external control center.
[0069] In this case, the control unit 160 of the lighting control
unit 100 can configure the event generation criterion in a
step-wise manner to allow different levels of responses.
[0070] In the end, the DVR unit 200 or the camera unit 300 can be
controlled, according to determination by the lighting control unit
100 on an event generated based on the sensing information of the
sensor 12 included in the lighting unit 13 without a separate video
analysis module, to sense intended objects 400 and 500 and acquire
a high quality video, thereby implementing a lighting providing
function in compliance with security function and situation.
[0071] In addition, the control unit 160 of the lighting control
unit 100 can dim one or more lighting units 14 and 15 associated
based on the associated lighting information included in the
corresponding operation contents according to the event through the
input/output unit 130. Accordingly, the control unit 160 can
control the illuminance of the associated lighting units 14 and 15
to be different from the illuminance of other lighting units,
thereby achieving attraction of attention, provision of illuminance
for high quality video acquisition and route guidance.
[0072] Here, one or more different lighting IDs associated with the
lighting ID of the lighting unit 10 generating the sensing
information selected for change in ambient brightness and route
guidance may be determined depending on type of the sensing
information and the event determination criterion.
[0073] The event determination criterion may include one or more
associated lighting IDs differently set for each lighting ID for
attraction attention or route guidance depending on type, sensing
level, position and environmental information of sensor unit 12
included in the lighting unit 10, and the associated lighting
information (associated lighting ID, dimming information, lighting
type, lighting time, etc.) for the associated lighting ID.
[0074] Accordingly, the control unit 160 can extract the
event-related information when an event is generated, and, based on
the associated lighting information included in the event-related
information, control the lighting units 14 and corresponding to the
associated lighting ID associated with the route guidance or the
attraction attention based on the information of the lighting
storage unit 152 of the DB unit 150, thereby carrying out the
function of route guidance or attraction of attention based on the
event-related information.
[0075] Here, the associated lighting information associated with
the attraction of attention may be omitted. That is, if it is
determined based on preset setting information that the sensing
information is information associated with a change in ambient
brightness, the control unit 160 can recognize a position of the
lighting ID generating the sensing information serving as the basis
of event generation from the lighting storage unit 152 of the DB
unit 150 and dim another lighting unit 14 adjacent to the lighting
unit 13 of the corresponding lighting ID, thereby increasing the
brightness of the ambient lighting unit 14 adjacent to the lighting
unit 13 of the corresponding lighting ID for attraction
attention.
[0076] In addition, the control unit 160 can display an event
generation spot by dimming the lighting unit 13 serving as the
basis of event generation, differently from other lighting
units.
[0077] An embodiment of control configuration of a lighting unit
based on the above-described event-related information for
attraction of attention or route guidance will be described in
detail.
[0078] First, as shown in FIG. 4, since the lighting unit is
provided with use for user recognition and trespassing prevention
in a case where the sensing information is information related to
object sensing, generated from a body sensor or a doppler sensor,
it is preferable to set an associated lighting ID for one or more
lighting units adjacent to the lighting unit from which the sensing
information is generated, in the associated lighting
information.
[0079] Accordingly, upon receiving the sensing information on
object sensing, the control unit 160 can determine whether or not
an event is generated, extract event-related information including
associated lighting information attached with an associated
lighting ID matching the lighting ID generating the sensing
information serving as the basis of event generation, from the
mapping table 151, and collate the extracted event-related
information with the lighting storage unit 152, thereby identifying
and dimming the lighting unit 13 generating the sensing information
and the adjacent lighting unit 14. This can attract attention of an
object and support to acquire a clear video from a camera, which
can result in great improvement of security.
[0080] As another example, as shown in FIG. 5, since the lighting
unit is provided with use for determination on occurrence of a
disaster in a case where the sensing information is information
generated from a fire sensor or a smoke sensor, it is preferable to
set an associated lighting ID for the lighting unit 15 placed on a
route to an exit 600 closest to a position of the lighting unit 13
generating the sensing information, in the associated lighting
information.
[0081] Accordingly, upon receiving the sensing information on fire
or smoke, the control unit 160 can determine whether or not an
event is generated, based on the associated lighting information
included in the event-related information, acquire an associated
lighting ID attached to information of a route to the exit 600
closest to the position of the lighting unit 13 generating the
sensing information serving as the basis of event generation, and
dim the lighting unit 15 matching the corresponding associated
lighting ID through the lighting storage unit 152. Of course,
lighting control such as sequential light emission, lightening or
the like is also possible.
[0082] Accordingly, a route from the position of the lighting unit
13 generating the sensing information to the exit can be guided and
a fire outbreak spot can be correctly guided through lighting,
thereby securing a field of view which may be blocked by smoke and
allowing earlier fire suppression.
[0083] In addition, the control unit 160 of the lighting control
unit 100 can control the external power receiving unit 110 and the
power providing unit 120 to provide power corresponding to desired
lighting to the input/output unit 130 and the dimmer unit 11 can
dim the entire lighting unit through a dimming control signal
received through the control line.
[0084] Based on the above-described configuration, depending on
security nature of a spatial position corresponding to each
lighting unit, a body sensor or a Doppler sensor can be applied if
the spatial position is intended to prevent trespassing and a fire
sensor or a smoke sensor can be applied to a space where disasters
such as fire concerns, thereby providing different security
functions for different positions in the space.
[0085] In addition, the sensor unit 12 included in the lighting
unit 13 may be configured with different types of complex sensors,
thereby allowing a body sensor and a fire sensor to be complexly
installed at specific spots.
[0086] Accordingly, if body sensing and fire or smoke sensing are
simultaneously generated, the objects 400 and 500 located at spots
where a fire breaks out can be shot to confirm identity of the
objects and a route from a spot of fire outbreak to the exit 600
can be guided, thereby allowing easy evacuation guidance or rescue
for a person located at a spot of fire or smoke outbreak.
[0087] In addition, since sensor application/no application can be
easily set without line change and accordingly additional sensors
can be provided or the type of the sensor can be changed as
necessary, it is possible to flexibly cope with various different
purposes.
[0088] In the other hand, if the sensing information is not
received in a certain period of time, the control unit 160 of the
lighting control unit 100 can initialize the entire lightings with
a preset dimming control setting of each lighting and transmit an
initialization signal to the DVR unit 200 or the camera unit 300
via the communication unit 140 in order to return the camera
operation based on the sensing information to its initial
state.
[0089] FIG. 6 is a flow chart showing an embodiment of a lighting
control method of the lighting control system with the
above-described security function. As shown, the lighting control
unit dims the entire lighting depending a preset lighting control
setting and one or more DVR units or camera units connected to the
lighting control unit are operated with an initial setting.
[0090] Thereafter, upon receiving sensing information and a
lighting ID from a lighting unit, the lighting control unit
extracts event-related information matching the lighting ID and the
sensing information and transmits a signal for corresponding
operation contents according to the event-related information to
the DVR unit or the camera unit.
[0091] Next, upon receiving the signal, the DVR unit or the camera
unit can control a camera based on the received signal to acquire a
high quality video for a sensing object and the lighting control
unit can control lighting associated with the lighting generating
the sensing information based the event-related information to
adjust the ambient brightness of a position corresponding to the
lighting generating the sensing information or provide guidance of
a route from the position to the exit.
[0092] Thereafter, if sensing information is not received any
longer, the lighting control unit can return the lighting under
control to the preset lighting control setting and return a camera
to the initial state by transmitting an initialization command to
the DVR unit or the camera unit.
[0093] While the present invention has been particularly shown and
described with reference to exemplary embodiments thereof, it will
be understood by those skilled in the art that various changes in
form and details may be made therein without departing from the
spirit and scope of the present invention. The exemplary
embodiments are provided for the purpose of illustrating the
invention, not in a limitative sense. Thus, it is intended that the
present invention covers the modifications and variations of this
invention provided they come within the scope of the appended
claims and their equivalents.
