Description

Cross-lane detection camera system

This creation is about the design of road monitoring systems, especially a cross-track detection camera system that uses scanning radar to detect violations such as red light, speeding or dangerous switching lanes.

In order to reduce the occurrence of traffic safety accidents, the Government has made a number of prohibitions to prevent the use of pedestrians. However, since it is impossible to monitor the manpower at each intersection, it is necessary to set up monitoring systems at various intersections to accurately grasp whether the vehicles have Violation.

In general, the more common monitoring system is an induction coil type. At least two induction coils are embedded under the area of each lane close to the intersection waiting line. The main arrangement method is three. One of the two coils is located at the intersection. In front of the line, the second is that the two coils are located behind the intersection waiting line, and the third is that the two coils are respectively located before and behind the intersection waiting line. The first type and the second type of embedding method are easy to cause disputes when photographing and ban, and there are many loopholes in judging. Therefore, the third type of embedding method is used for detection. The induction coil is interconnected with a stationary camera system, and the vehicle is passed through an induction coil and the inductance value is varied to make a determination. However, when embedding an induction coil, it is necessary to dig a region for burying the induction coil in the lane, which covers a large area and is not easy to construct. It will damage the road surface during installation and construction, affecting the smoothness of the road surface, and the coil is easily affected by environmental influences in the underground. In addition, the induction coil is susceptible to damage caused by vehicle extrusion and road repair during long-term use, and needs to be replaced on average for 2 to 3 years. The maintenance cost is relatively increase.

Therefore, the creator conceived a cross-lane detection camera system, which hopes to solve the lack of the above traditional lane monitoring system.

One of the purposes of the present invention is to provide a cross-lane detection camera system that utilizes at least one laser sensor and forms at least one first sensing area in the lane to detect the condition of the vehicle passing through the sensing area. Whether there are violations such as red light or overspeed, and if the laser sensor is installed in the middle of the lane, it can further know the dangerous switching lane condition of the vehicle, so as to have the effect of multiple detection.

Another object of the present invention is to provide a cross-lane detection camera system that assists in sensing the passing condition of the vehicle through at least one sensor to improve the accuracy of detection.

In order to achieve the above objectives, the cross-track detection camera system of the present invention is installed on a roadside to detect violations of vehicles such as red light or speeding, and photograph or photograph, the road has at least one lane, and the road is Corresponding traffic light is provided with a waiting line, comprising: a bracket disposed on one side of the road; at least one laser detector disposed on the bracket and forming at least one first sensing area in the lane, and the first The sensing area is perpendicular to the lane, and the laser detector detects the passing condition of the vehicle through the first sensing area in a scanning manner; and a camera device is disposed on one side of the road and has a control host and a camera, the camera device is in telecommunication connection with the laser detector to transmit the detection result of the laser detector to the control host, and the control host drives the camera to take photos of the offending vehicle or photography.

The laser detector is correspondingly disposed above the lane, and the bracket may be a traffic light support frame or a road sign support frame.

When the lane is set in plural, the laser detector is set to correspond to the number of lanes, and further, the bracket corresponds to the adjacent lane center line, and the laser detector is also provided. The lane lines of the lanes form a second sensing zone.

The laser detector 11 is disposed on the bracket 10 and defines a first sensing area 111 in the lanes 2, and the first sensing area 111 is perpendicular to the lanes 2 and located at the waiting line 20 Preferably, the laser detector 11 is disposed corresponding to the number of lanes 2, and the laser detectors 11 are disposed above the lanes 2. The laser detectors 11 continuously emit lasers toward the first sensing area 111 in a scanning manner to detect the passing condition of the vehicle and transmit the reflected and reflected laser beams to know whether the vehicle has a red light violation. The matter, and through the distance d between the two lasers emitted at different times and angles, combined with the time difference of the vehicle passing through, the vehicle speed can be calculated to determine whether there is a violation of the speeding. The scanning type of the laser detector 11 can prevent the external environment factors such as rain or fog from affecting the accuracy of the detection, and since the speed of light is extremely fast, the result can be immediately transmitted to ban the violation.

The camera device 12 is disposed on one side of the road and has a control host 121 and a camera 122. The camera device 12 is in telecommunication connection with the laser detector 11 to receive the laser by the control host 121. The detection result of the detector 11 is further determined whether a violation occurs, and the camera 122 is driven to take photos, continuously photograph, and photograph the illegal vehicle. When the sensing area 111 senses the passage of the vehicle when the red light is emitted, the laser detector 11 transmits the scanning result to the control host 121, and the control unit 121 drives the camera 122 to obtain the effect of ban.
