AI Technical Summary
In traditional traffic light control systems, the complexity, reduced efficiency, energy loss, and response time delay caused by rectification and filtering circuits make it difficult to capture traffic light signals and adapt to changing needs and environments.
By configuring a resistor network to stabilize the input current within a safe operating range, and using opto-isolation elements to generate a square wave signal that is phase-synchronized with the AC sine wave signal, the zero-crossing trigger event is captured. Combined with the external interrupt function of the central controller, the traffic light signal can be captured quickly.
By eliminating the rectifier and filter circuit, accurate capture of traffic light signals is achieved, improving operational efficiency and flexibility while reducing system complexity and cost.
