| 中文摘要: |
| 研究一种基于电力线通信技术的铁路信号灯监测系统，原理是LED铁路信号灯故障信息表现为信号灯限流电阻上电压的变化，通过单片机采集信号灯限流电阻上的电压信息，经低压电力线传输，在接收端接收到故障信息后进行声光报警，实现铁路信号灯故障检测的自动化。 |
| 英文摘要: |
| The principle is that the fault information of LED railway signal is represented as the variation of the voltage on the current limit resistance of the signal lamp. The voltage information on the current limiting resistor of the signal lamp is collected by the single chip microcomputer. Through low voltage power line transmission, the sound and light alarm after receiving the fault information at the receiving end. The automatic fault detection of railway signal is realized. |
