Intelligent Operation and Maintenance System for Urban Rail Transit Switch Machines

A switch machine is a core equipment of a signal system with the largest maintenance volume, strongest maintenancedifficulty, and a wide range of equipment failures. With the increase in intelligent operation and maintenance research in the urbanrail transit industry, research on intelligent operation and maintenance of switch machines has attracted the interest of industry scholars.It is the foundation for achieving intelligent maintenance of urban rail signals and intelligent operation and maintenance productionorganization modes. This article summarizes the limitations of traditional microcomputer monitoring systems and proposes anintelligent system based on the maintenance difficulties and pain points of switch machines in the industry. The system includes criticalstate perception, intelligent fault diagnosis, critical state warning, and health assessment, and proposes specific implementationmethods. The system was successfully applied to Nanning Metro Lines 4 and 5, and significant benefits were obtained.
