铁路信号设备防雷集中监测系统的设计

摘要

As one of the main long distance vehicles in China, it is especially important to ensure the security of railway transportation. According to the requirements of railway work of the lightning protection,a railway signal equipment lightning protection centralized monitoring system is designed. Using the embedded RT-Thread operating system and TCP/IP protocol for the host computer communication, monitoring equipment of the system has the core functions including real-time trigger, real-time data acquisition, real-time monitoring, remote management etc. These functions change the current situation that lightning protection device can' t have a fast feedback. The field test operation of the system shows that the system has strong anti-interference capability and stability. It also improves the reliability of lightning protection equipment of railway signals.%铁路运输作为我国主要的长途交通工具,保证其安全运营的意义尤为重要.针对铁路防雷工作的需求,设计了一种车站信号设备防雷集中监测系统.集中式监测系统采用嵌入式RT-Thread操作系统,与上位机通信采用TCP/IP协议,具有实时触发、实时采集、集中监测、远程管理等核心功能,改变了现有防雷器工作状态不能快速反馈的现状.该系统现场测试运行表明,系统抗干扰能力强,工作稳定,提高了铁路车站信号防雷设备的可靠性.
