The control system of LED traffic lights

Traffic light controller: It is the core component of the traffic light control system, responsible for generating corresponding control signals according to traffic rules and real-time conditions, and sending them to traffic lights. Traffic light controllers can be implemented using different technologies, such as PLC, FPGA, microcontroller, etc.

Traffic light: it is the output part of the traffic light control system, which is responsible for displaying the corresponding color or pattern according to the signal of the controller, indicating the driving or stopping of vehicles and pedestrians. Traffic lights generally use LEDs (light-emitting diodes) as light sources, which have the advantages of energy saving, environmental protection, long life, fast response, and bright colors.

Transmission line: It is the connection part of the traffic light control system, which is responsible for transmitting the signal of the controller to the traffic signal light. Transmission lines can be realized in different ways, such as current loop, optical fiber, wireless, etc.
