Abstract: Aiming at the many problems existing in the maintenance of urban rail transit signaling equipment, a new active maintenance mode that uses health evaluation model to establish an intelligent monitoring platform is put forward. Through the research of signaling equipment and analysis of monitoring data, combined with corresponding national standards and empirical data indicators, a health assessment model at equipment level, station level and line level is established. The intelligent monitoring platform is further established to realize the active maintenance and intelligent management of urban rail transit signaling equipment.
