Abstract：Subway operation security is a mater of great importance，the state in which the transmission is a key element of the contact rail subway can affect normal operation. Starting from the detected contact rail state transmission parameters，analyze contact rail deformation generated key reasons，put forward key parameters stand detection by implementing a holder vision and other sensor-based intelligent online monitoring，and analysis of real-time and historical data in the host computer system to achieve on-line monitoring and off-line analysis and diagnosis，it has been effectively applied in practice.
