| 摘 要： | 针对无人值守铁路道口安全，设计了一种基于可编程控制器（programmable logic controller，PLC）的道口自动控制系统。系统采用无源磁电式列车检测传感器检测，通过无线收发装置获取列车信号，根据检测信号通过道口自动控制系统和远程监控系统来实现对无人值守道口的自动控制。为提高系统的可靠性，系统增加红外检测和视频监控模块。该系统具有很强的实用性，现已投入使用。

| Abstract: | For unmanned railway crossing safety, this paper designs an automatic control system based on PLC. The system uses passive magnetic-electric train detection sensors, via wireless transmitters and receivers to get the train through signal. According to the test signal, the automatic control system and remote monitoring system control the unmanned railway crossing. In order to improve system reliability, increased infrared and video surveillance. The system is very practical, and has been used. |
