[0026] The second output normally open contact of the bidirectional feedback controller U3 is connected to one end of the B3 relay winding, one end of the B2 relay winding and the negative electrode of the diode D4. The positive electrode of the diode D4 is connected to the normally closed contact of the E relay. The other end of the B3 relay winding is connected to the negative output end of the rectifier VD1. The other end of the B2 relay winding is connected to the normally closed contact end of the A2 relay. The common end of the A2 relay is connected to the negative output end of the rectifier VD1.

[0029] When starting, the two bidirectional feedback controllers U3 are powered on and drive the corresponding addition and subtraction counting modules U2 to return to zero, and the D relay is energized. Figure 1 The green lights on the left and right sides are on.
[0030] When a car travels from left to right and passes the first infrared beam switch U5 of the photoelectric vehicle detection module on the left, the A1 relay is energized, the normally open contact of the A1 relay is closed, and the switch signal is sent to the first signal input terminal of the corresponding two-way wireless controller U3, and is transmitted to the two-way wireless controller U3 of another control subsystem through the two-way wireless controller U3.
