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.
