The present invention relates to a traffic monitoring system. In particular, once a monitoring zone is set at a certain distance from a stop line, when a vehicle enters this zone, the vehicle detects a pain signal violation and photographs the traffic signal violation vehicle as a still image. The present invention relates to a traffic monitoring system for unattended monitoring of traffic conditions on roads and intersections.

Currently, traffic police officers are located in certain areas or designated areas to monitor traffic violations such as parking violations, signal violations, and speed violations on streets, roads, etc. Many drivers are rushing by ignoring the traffic lights, which causes many traffic accidents, and it requires a lot of manpower to monitor traffic violations, which is a big burden on national finance.

In addition, due to the lack of manpower and long-term work of traffic police officers, there are excessive casualties and physical damages caused by boredom and fatigue, and traffic police officers who have to carry out road traffic cause irregularities and distrust between the Japanese-American samurai and the slaves. Distrust has been seriously raised by the public.

In addition, even if there is a traffic monitoring system, the system itself is an analog system, and thus it is not connected with the digital traffic control system currently in use, and also lacks in backward technology.

Therefore, in order to prevent traffic accidents caused by signal violations on the road, the present invention detects signal violations by receiving a traffic light control signal of a traffic control system and a vehicle detection signal of a detector to prevent traffic accidents. It is an object of the present invention to provide a traffic monitoring system that can control all weather day and night detections unattended by processing a still image of a signal violation vehicle.

In order to achieve the above object, the present invention operates a camera according to a traffic light control signal supplied from a traffic control system and a vehicle detection signal supplied from a detector to process still images of a vehicle image supplied from the camera. And a local control device which records and stores information on the color of the shooting date, time, and violation signal, etc., together with the still image, and receives a still image transmitted from the local control device, and captures the still image. It provides a traffic monitoring system that includes a central control unit that outputs a photo with information on color, time, and traffic lights.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The local control apparatus 100 includes a power supply apparatus 10, a main control apparatus 20, an image processing apparatus 30, a logic control circuit 40, a camera control apparatus 50, and a transmission apparatus 90. In response to the signals supplied from the traffic control system 60 and the detector 70, the vehicle detects the signal violation vehicle and captures the detected signal violation vehicle through the camera 80 to process the still image, and capture the date, time and Record the violation signal light information and transmit it to the central control unit (160). The central control unit 160 includes a power supply unit 110, a main control unit 120, an image processor 130, an image output unit 140, and a receiving unit 150, and the local control unit 100. Outputs the time according to the still picture received from.

In FIG. 1 showing the traffic monitoring system according to the present invention, when the power switch (not shown) of the power supply device 10 is turned on, power is supplied to all circuit portions of the local control device 100. The detector 70 is composed of first and second detectors (not shown) such as an oscillation loop, an optical detector, a metal detector, and a motion detector, and when a vehicle enters a certain area (see FIG. 3). It detects and generates a detection signal. The logic control circuit 40 receives the vehicle detection signal from the detector 70 and the traffic light control signal from the traffic control system 60, and receives the vehicle detection signal and the traffic light control signal from the traffic control system 60. The conversion is performed, and the resultant signal is output to the main controller 20 side. The main controller 20 controls the operation of the camera control device 50 and the image processing device 30 in accordance with a signal supplied from the logic control circuit 40. The camera controller 50 operates the camera 80 according to the control of the main controller 20 (in this case, the camera 80 faces the license plate of the vehicle), and the image processing apparatus 30 moves to the camera 80. The image of the signal violation vehicle supplied from the still image process is processed under the control of the main controller 20. The main control unit 20 records information such as photographing date, time, color of violation signal, etc. in the still image, and stores the information in the image processing apparatus 30, and then controls the transmitting apparatus 90 to store the still image in the central controller 160. To the side.

The power supply unit 110 supplies power to each circuit of the central control unit 160. The receiving device 150 of the central control device 160 receives the still picture transmitted from the transmitting device 90 under the control of the main controller 120 and outputs it to the image processing device 130. The image processing apparatus 130 outputs the still image supplied from the receiving apparatus 150 to the image output apparatus 140 under the control of the main controller 120, and the image output apparatus 140 is the image processing apparatus 130. The still picture supplied from the main controller 120 is output in the form of a picture under the control of the main controller 120. In the picture output from the image output device 140, information about the color of the shooting date, time, and the violation signal is recorded together.

Referring again to the drawings, the existing traffic control system 60 of the traffic control network generates the traffic light control signals (R), (Y), (G) and the failure control signal (F). As shown in FIG. 2, the logic control circuit 40 includes an OR gate 41 which receives the red traffic light control signal R and the yellow traffic light control signal Y as the first and second inputs, and logically combines the green and the OR gates 41. An inverter 42 for inverting the traffic light control signal G, an AND gate 44 for receiving and ORing the output of the OR gate 41 and the output of the inverter 42 as first and second inputs, and a failure control signal. An inverter 43 for inverting (F), an AND gate 45 that receives and outputs the output of the inverter 43 and the output of the AND gate 44 as first and second inputs, and the first detection signal D1. And an AND gate 46 for receiving and outputting the output of the AND gate 45 as the first and second inputs, and receiving the output and the second sensing signal D2 of the AND gate 46 as the first and second inputs. It consists of an AND gate 47 to multiply.

The OR gate 41 receives the red traffic light control signal R or the yellow traffic light control signal Y from the traffic control system 60 in the absence of the input of the green traffic light control signal G and the failure control signal F. When receiving, the output of the OR gate 41 becomes "1" and enters the first input of the AND gate 44, and the second input of the AND gate 44 has an inverter for inverting the green signal lamp control signal G ( Accept the output of 42). Then, since both inputs of the AND gate 44 are "1", the output thereof is also "1". Since there is no input of the failure control signal F, the output of the inverter 43 becomes "1" and is input to the AND gate 45. Therefore, the AND gate 45 which receives the output of the inverter 43 and the output of the AND gate 44 outputs "1".

In FIG. 3, when the traffic light turns into a red light or a yellow light, the first detection signal D1 is generated from the detector 70 when the vehicle passes the first detector installed at a certain distance from the stop line, thereby generating an AND gate ( 46). After the AND gate 46 receives the output signal of the AND gate 45 and the first detection signal D1, and supplies the output S1 to the main controller 20, the main controller 20 is the camera controller 50. The camera 80 is operated through the camera 80 such that the vehicle image from the camera 80 is supplied to the image processing apparatus 30. When the vehicle passes the second detector installed at a certain distance from the first detector, a second detection signal D2 is generated from the detector 70 and supplied to the logic control circuit 40. The AND gate 47 of the logic control circuit 40 receives the second sensed signal D2 from the detector 70 as the second input and receives the output of the AND gate 46 as the first input. When supplied to the apparatus 20 side, the main control unit 20 controls the image processing apparatus 30 to perform a still image processing of the image from the camera 80.

At this time, the main control unit 20 records the information on the color, such as the shooting date, time and violation signal in the still image processed image and stores it in the image processing apparatus 30, from the traffic control system 60 to the logic control circuit ( Record the information on the color of violation signal in accordance with the state of traffic signal control signal. Thereafter, the main controller 20 transmits the still image to the receiving apparatus 150 side of the central control apparatus 160 through the transmitting apparatus 90 when it is necessary to transmit the still image to the central control apparatus 160 side. Subsequent operations of the central control unit 160 are processed through the above-described process.
