Road traffic light control system works

In the road traffic signal control system, to the end of the road traffic lights all process, need to use the main controller, control circuit, counter, timer, decoder, clock signal generator, signal decoding drive circuit and digital flash decoding drive circuit.

 

Second pulse generator is timer and controller in the system the specification of the clock signal source; Decoder output the control signals of the two sets of lights, after driving circuit driving lights work; Controller is the first some of system, the control of the timer and decoder by it.

 

And then by the clock signal generator to the main control circuit and counter, counter to the decoder, finally to blink blink out, comment the background details in the back to the main control circuit, after a decoder is passed on to the road traffic lights, flashing respectively on the main road, road traffic lights.

 

The above introduction, the content of the is road traffic light control system works. But, according to the regional environment different, road traffic lights specifications and working principle of the control system may also be different. Especially in road traffic light control system, different regional environment of the different moment of intersection traffic signal lamp and whether traffic set is not the same.
