Health Status Monitoring System for Railway Signal Spare Parts
In railway signal operation,spare parts are important instruments related to railway maintenance and even transportation safety.In the process of production and operation,when the failure caused by improper management of spare parts or their own performance degradation is handled with delay,it will become a potential risk factor threatening train operation safety.Therefore,the railway sector attaches great importance to the maintenance management of spare parts.In combination with the current management status of signal spare parts in the communication&signaling systems of various railway administrations in China,this paper analyzes the defects in the current management of spare parts,builds a real-time health status monitoring system for railway signal spare parts,designs acquisition and monitoring circuits for analog quantity and switching value respectively,and gives data offline analysis logic and alarm disposal scheme,providing a reference for improving the management level of spare parts in high speed railway projects.
