| Abstract: | An automatic detection system for LED traffic lights is presented.The system adopts the Power Line Communication mode to collect signals and transmit data,and then the controller performs the fault detection to implement the auto-detection and alarm report.For the crossing in actual condition,the data transmission of the system is reliable and keeps up with the time.This can meet all the requirements for the auto-detection of the LED traffic lights.Thus the LED can run efficiently and normally to guarantee the traffic conditions of roads. |
