Referring to the drawings, the streetlight control system 1 may include a plurality of streetlights 100 and a streetlight dimming control device 200 attached to each streetlight 100, for example.

The street light 100 may be installed in a residential area or a business district such as a sidewalk, a sidewalk, and a road, and may be installed in an area with a low flow rate for security and security rather than a frequent pedestrian area.

The streetlight 100 may be a light emitting diode (LED) as a light source. In particular, it may be configured to control dimming. The dimming control signal may be input to the streetlight 100, The brightness of the light source can be adjusted by adjusting the brightness of the light source.

The streetlight dimming control device 200 for controlling the dimming operation of the streetlight 100 may be mounted at a certain height of the streetlight 100, as shown in Fig.

The streetlight dimming control apparatus 200 includes an illuminance sensing unit 210, a dimming control unit 220, a distance sensing unit 230, a control communication unit 240, a storage unit 250, and an input unit 260 .

The illuminance detecting unit 210 may include a light metering sensor or the like for detecting the external illuminance of the streetlight 100. The illuminance detecting unit 210 may measure the illuminance of day and night in real time, Lt; / RTI > The generated illuminance information may be provided to the dimming control unit 230 and the storage unit 26, which will be described later.

The motion sensing unit 220 may sense the movement of the pedestrian 10 within a certain range (radius) in which the streetlight 100 is installed. The motion detection unit 220 may include an ultrasonic sensor using ultrasonic waves.

The dimming control unit 230 may be configured to output a dimming control signal to control the operation of each component of the streetlight dimming control apparatus 200. [

The dimming control unit 230 outputs a dimming control signal in accordance with the illumination information generated by the illumination sensing unit 210, and the streetlight 100 can be controlled to perform lighting, blinking, and dimming functions based on the dimming control signal have.

Specifically, the dimming control unit 230 may control the streetlight 100 to be lit and blinked after sampling the illuminance information and checking whether the illuminance corresponds to the detected illuminance level or the illuminance level.

The dimming control unit 230 sets the reference illuminance according to the external illuminance sensed in real time through the illuminance sensing unit 210 and controls the dimming control unit 230 to illuminate the streetlight 100 with the brightness corresponding to the set reference illuminance Lt; / RTI >

When the movement of the pedestrian 10 is sensed within a certain range through the motion sensing unit 220, the dimming control unit 230 causes the dimming control unit 230 to operate with the dimming brightness set in the reference illuminance, It is possible to control the illumination of the street lamp 100 with the brightness corresponding to the brightness.

In addition, the dimming control unit 230 may control the motion sensing unit 220 to operate when the external illuminance sensed by the illumination sensing unit 210 is in a set range. That is, the motion sensing unit 220 may be controlled to operate at a nighttime when the external illuminance is low, or in a situation where the streetlight 100 should be lit, instead of always operating for 24 hours.

The distance sensing unit 240 may include a position detecting module 241, an interval calculating module 242, and a distance calculating module 242.

The position detection module 241 detects each position (coordinate and distance information, etc.) of a plurality of motions sensed through the motion sensing unit 220 and the interval calculation module 242 The distance between each motion can be calculated from each detected position. In addition, the interval checking module 243 checks whether the interval between motions calculated through the interval calculating module 242 is within a set distance interval.

If it is confirmed through the interval checking module 243 that the interval between the motions is within the set distance interval for a predetermined time, for example, if the interval d between the pedestrian 11 and the pedestrian 12 is within the set distance interval, The control unit 230 can control the streetlight 100 to be illuminated more brighter than the set dimming brightness (i.e., a state illuminated more brighter than the reference illuminance by motion sensing).

If it is confirmed that the interval between the motions is out of the set distance interval through the interval checking module 243 and the distance between the pedestrian 11 and the pedestrian 12 is increased, Can be controlled.

As described above, by adjusting the brightness of the streetlight 100, the pedestrian 10 can recognize the changed illuminance, thereby preventing an accident that may occur during the night time.

The storage unit 250 stores control information including reference illumination information and dimming brightness information for lighting and extinguishing the streetlight 100 and identification information of the streetlight dimming control apparatus 100 and identification information And event information and the like generated by the respective components of the streetlight dimming control apparatus 100 can be stored in real time.

In addition, the storage unit 250 may store information such as an operating program, environment variables, and the like for driving the streetlight dimming control apparatus 100, and may include an EEPROM or various types of devices.

The control communication unit 260 may perform wireless or wired communication with the streetlight dimming control device 200 or a user terminal (not shown) attached to the adjacent streetlight 100.

In particular, the control communication unit 260 provides the dimming control signal output from the dimming control unit 230 to the adjacent preceding streetlight dimming control apparatus 200, and the preceding streetlight dimming control apparatus 200 receives the dimming control signal It is possible to control the illumination of the streetlight 100 to which the dimming control signal is transmitted to be adjusted to the set dimming brightness.

Therefore, while one streetlight 100 is controlled to have a set dimming brightness, the streetlight 100 near the position of the preceding streetlight 100, i.e., the pedestrian 10, is controlled according to the position of the pedestrian 10 So that it is possible to predict the traveling direction of the pedestrian 10, thereby brightening the illumination of the street light 100.

The input unit 270 may be a keyboard or a separate terminal and may be connected to the control communication unit 260 by wire or wirelessly to input external command or variable information to the streetlight dimming control apparatus 200, The information input through the input unit 270 may be stored in the storage unit 250.

The input unit 270 may be integrated into the streetlight dimming control apparatus 200, or may be applied to a remote server or a PC.

As described above, in the streetlight control system according to the present invention, it is possible to reduce the carbon emission by reducing the power consumption by controlling the brightness of the streetlight according to the moving direction of the pedestrian and the surrounding situation, There is a characteristic that can be done.
