When the electric control box component 6 needs to be maintained, the position of the switch clip 605 is moved. At this time, the clip spring 606 is squeezed and contracted. When the switch clip 605 leaves the clip slot 604, the electric control box door panel 601 can be opened for maintenance of the interior;

[0033] Next, the device uses video processing and human detection technology to automatically locate, track, detect, and identify pedestrians in the video in real time and frame by frame. By setting the identification area, it focuses on detecting pedestrians on the zebra crossing and in the waiting area at the intersection. The status of the traffic light is identified according to the traffic light signal detection module. When the traffic light is in the red light state and a pedestrian enters the zebra crossing and moves forward and backward, the capture program is started and the violation data is saved. At the same time, the number of people in the opposite waiting area is counted in real time, and the data is sent to the signal machine through the network to control the switching of the traffic light. When the traffic light is in the green light state, the device will count the number of pedestrians on the zebra crossing in real time, and send the data to the signal machine through the network to extend or shorten the current green light duration.
