文中分析了目前铁路平交道口3种监控系统的特点及不足:基于单片机的道口监控系统结构简单、成本低廉,但该系统信息只能单向传输;基于ARM和GPS、GPRS的道口监控系统实现了道口与司机的通信,但在GPRS网络盲区通信得不到保障;基于工控机的道口监控系统组成复杂,花费巨大.基于以上的分析提出一种无线安全监控系统方案:当列车运行接近道口时,触发传感器,发射装置将列车运行方向、 速度等信息通过无线方式发射,接收装置接收到信号后启动报警系统. 该系统结构简单、成本低廉、能实现司机与道口值班人员之间的联系. 通过计算和实验验证表明:即使在阴雨天,系统也可在列车通过道口前1.5min得到预警信息,实现了铁路道口的安全监控和信息管理.

This paper analyzes the characteristics and problems of three current railway crossing monitoring system: The crossing monitoring system based on SCM has simple structure and low cost, but the information can be transmitted unilaterally; the crossing monitoring system based on ARM , GPS and GPRS, realizes communication of crossing and the driver, but it doesn't work in the blind area of GPRS network;the composition of the crossing monitoring system based on IPC is very complex, costly. According to the analysis,a new wireless safety monitoring system is designed: When the train approaching the crossing trigger sensor, transmitting apparatus transmits the train running direction, speed and other information, through wireless way, after receiving the signal, receiving apparatus starts the alarm system. The system has the advantages of simple structure, low cost, which can realize the communication between the driver and the crossing operator. Calculation and experimental verification show that:even in rainy days, the early warning information can be received in 1.5 minutes before the train passing through the crossing, the system achieves the safety monitoring and information management of railway crossing.
