摘　　要：该文设计了一种适用于LED交通信号灯工作状态及故障检测的系统。系统通过低压电力线载波通信方式完成对采集的LED交通信号灯工作状态的数据传输,并由控制器完成对LED交通信号灯的故障检测,以达到自动检测和报警的目的。经在智能交通系统中实际应用,证明了该系统数据传输可靠,实时性强,完全能满足LED交通信号灯的自动检测要求,使LED交通信号灯能有效、正常运行,保证了道路交通的通行质量。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.
