摘　　要：为满足当前铁路道口安全运营的需求,利用铁路沿线铺设的光缆及相位敏感光时域反射计技术,对铁路道口列车接近的实时状态进行安全监测和预警,通过建立网络化的列车接近安全预警系统,保障铁路道口列车运行监控数据的准确性和可靠性。To ensure the safe operation of railway level crossing, a new monitoring system has been built by using existing optical communication cable and phase-sensitive optical time domain reflect steps （φ-OTDR）. The system can monitor the real--time state of train approaching and send off early warning. By connecting to the specialized network, the monitoring system can act as an effective way to guarantee the accuracy and reliability of train approaching monitoring data.
