城市轨道交通轨道电位的监测是维护城市轨道交通安全稳定运行的重要部分。文中提出了轨道电位在线监测系统的总体架构，利用Internet、地铁局域网和CAN总线相结合
的通讯方式，对系统的各个组成部分进行了研究，给出了现场总线与局域网的接口解决方案并对系统所用的传感器进行了设计。该系统已在地铁现场进行了实验验证。结果表明，该系统对轨道电位监测实时准确，具有可靠性高，成本低等优点。
关键词：局域网，轨道电位，监测，地铁
Abstract: Urban mass transit rail potential monitoring is an important part of
maintenance its safe and stable running. The overall structure of on-line rail potential
monitoring system has been provided, by use of the Internet, LAN and CAN Bus
combination of means of communication. The various components of the system were
studied. Fieldbus and LAN interface solutions have been given and the sensor used
in the system has been designed. The system has been tested in the subway. The
results show that the monitoring system to rail potential with accurate and real-time is
high reliability and low cost advantages.
