Road signal lamp interaction system based on distributed control

The utility model relates to the technical field of road traffic control, and discloses a road signal lamp interaction system based on distributed control, which comprises a control main end and a signal lamp end. The control main end is connected with an output terminal of a signal machine and used for collecting and recording control information, output by the signal machine, of the signal lamp end to obtain signal lamp control logic, and the signal lamp end is in communication connection with the control main end, is internally provided with a lamp end processing module, receives the signal lamp control logic sent by the control main end and sends the signal lamp control logic to the signal machine. And the on-off output of the built-in three-color light-emitting unit is controlled according to the signal lamp control logic. Therefore, the signal lamp end can store the control logic, and the signal lamp end can continue to operate according to the stored control logic without being controlled by the signal
