"Congestion."

Electronic products such as "LED signs" and "LED induction display screens" have been used more and more widely in the "variable lane" project, which puts forward higher requirements for the control system. PLC controller With its characteristics of good stability, strong anti-interference ability, and visual operation, it can be used as the main control unit, combined with the relevant phase output signal of the road traffic signal control machine, to realize "intelligent control", and it can also be realized in emergency situations. "Manual operation" can deal with various complex environments at intersections and realize scientific management.
