DC Track Circuit and Point Machine Health Monitoring Unit
DC Track Circuit health monitoring unit is used for detecting the electrical energies at feed and relay ends of the track circuit. It is possible to have an early warning before the track relay drops and cause signal failure or over energized beyond maximum limit and cause unsafe side failure.
Point Machine Health monitoring unit indicates the point machine’s health by monitoring its current along with status of point control, operating and detection relays. By this signal technician can reduce the down time of the point in case of failure as the failure state is already made available by the system. He can plan for need based maintenance which reduces the disconnection time. In case of simple obstruction the station master is guided by the system i.e. on which end to check for obstruction.
Modules in Point Machine Health Monitoring Unit :
Mini Logger :
This is capable of monitoring the Current and Voltage parameters of point machines and this acquired data will be sent to Event Logger through Wireless communication.
