铁路道口远程安全监控系统设计

介绍一种利用嵌入式系统和GPRS技术相结合,实现铁路道口远程监控及告警和列车接近预警的应用系统。详细描述了系统组成结构、硬件原理设计和软件实现方法。通过该系统不仅使列车接近道口时有声光报警,而且可以使得铁路道口管理部门不用到达道口所在位置,通过铁路道口控制中心的检测平台,就可以对整个辖区内的铁路道口设备工作状态和道口通过列车的车流量进行全面监控,从而迅速地了解道口设备的故障类型,在最短时间内保证设备正常运行,同时也便于铁路道口的监管部门对其道口监护员的工作进行远程监控。

Design of Remote Monitoring System of Railway Crossing

This paper introduced an application system of remote monitoring and train approaching warning at railway junction, which combined embedded system with GPRS technology. Its composition, principle design of hardware, and software implementing method were described in detail. Through using the system, not only sound and light alarm can be initiated while a train was approaching, but also the working condition of crossing equipment and the train flow could be fully monitored by railway administration through the detection platform of railway crossing control center in advance of train arriving at the crossing. Thus the types of faults of railway crossing equipment can be quickly noticed and it guarantees that the equipment could return normal work as soon as possible. Meantime, it is convenient for the railway crossing supervision department to carry out remote monitoring over the work of crossing supervisor.
