Detailed ways

The present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention, and provides a detailed implementation manner and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

An off-line special vehicle intelligent traffic signal light 2 control system, as shown in Figure 1, includes a control device 3 for controlling the work of the traffic light 2, a vehicle identification device 1 for detecting whether the vehicle is a special vehicle, and the control device 3 respectively. It is connected with the signal light 2 and the vehicle identification device 1, and the control device 3 is connected with the signal light 2 and the vehicle identification device 1 through cables. The system also includes a mounting bracket, as shown in Figure 2 and Figure 3, the mounting bracket A cross bar 5, as shown in FIG. 4, is provided with a channel 6 for cable layout in the upright column 4 and the cross bar 5, the four upright posts 4 are respectively located at the four corners of the intersection, and the four cross bars 5 are respectively connected with the junction. The four sides are corresponding and parallel, each cross bar 5 is connected with two adjacent uprights 4 respectively, and the channel 6 in it is connected with the channel 6 in the two uprights 4, and the four signal lights 2 used to direct the vehicles at the intersection are respectively The vehicle identification device 1 is located on the four cross bars 5 , and the four cross bars 5 are all provided with the vehicle identification device 1 .
