As is known to all, the road traffic signal light is an important guarantee for maintaining traffic order and ensuring traffic safety and unimpeded traffic. And in our daily lives, when we pass a crossroads or a t-shaped intersection, we may notice that the time setting of the upper set of road traffic lights that direct traffic east, west, south, and north will be different on the main and secondary roads. The time setting on the traffic lights is mainly set by the control system. So how does the traffic signal controller work?

How Traffic Signal Controller works:

In the traffic signal controller, if you want to complete the flow of a road traffic signal, need to use the main controller, control circuit, counter, timer, decoder, clock signal generator, a signal decoding driver circuit, and digital display decoding driver circuit.

The second pulse generator is the standard clock signal source of the timer and the controller in the system, the decoder outputs the control signals of the two groups of signal lights, and drives the signal lights to work after the driving circuit, and the controller is the main part of the system, it controls the work of the timer and decoder.

The clock signal generator is then passed to the main control circuit and counter, the counter is passed to the decoder, and finally, the display is displayed to inform the background that the situation is being transmitted back to the main control circuit, it is transmitted to the road traffic signal lamp by the decoder and displayed on the road traffic signal lamp of the main road and the secondary road respectively.

The above-mentioned content is the road traffic signal light control system principle of work. However, according to the regional environment, the road traffic lights installation specifications and control system work principles are also different. In particular, in the traffic signal controller, the time and traffic setting of traffic lights at different intersections in different regional environments are also different.
