基于电力线列车网络的旅客列车安全监测系统试验研究

Experimental Study on Power Line Communication Based Alarm System for Monitoring Passenger Train Safety Monitoring System

研究基于电力线列车网络的铁路旅客列车安全监测系统。采用Lonworks电力线列车网络,针对普通客车非固定编组的管理模式的需求,在带宽较窄的电力线通信网络上,设计了普通客车安全监测列车网络解决方案。介绍了系统各主要部分的结构原理及实现方法,在列车监测仿真试验室的列车监测仿真试验台上进行的运行考核试验表明,系统本身可以做到工作稳定可靠。系统还做了与列车轴温集中报警系统并行布线运行试验,目前发现有一些互相干扰问题,在实际装车运用时还需解决该问题。

In this article,we describe an alarm system designed for monitoring the railway trains.The monitoring system relies on network communication over the power lines and can be adapted to regular passenger coach cars.Using PL3150 power line smart transceiver we achieved network communication over existing control cables that offers high reliability and cost-reduction.This system is compatible with random grouping of passenger cars,therefore provides a complete network solution for monitoring of safety through the narrow bandwidth in the power line communication network.This paper introduces each of the principal components of the system,architectural principles and implementation methods.We have conducted simulated train operation tests in the simulation laboratory and demonstrated that the overall design is rational and the system is stable and reliable.
