Point Machine Health Monitoring Unit
This system indicates the point machine’s health by monitoring its current, common power supply and DC Earth Leakage Detection (ELD) voltage supplies along with operations (Relay status) there by allowing railway operators to perform preventive maintenance.
Salient Features:
Micro-controller based system
Monitors the following types of point operations
Single Ended operations
Double Ended Serial operations
Able to monitor combination of both types of Point operations
Maximum of 48 Point Motors can be monitored
Scanning rate of Current and Voltages is 32 samples per second
Graphical representation of Current and voltage characteristics of point machine during point operation
Provision to compare selected point operations for selected point machine with the ideal reference graph.
Generating exceptions and alarms when current, voltages or point operation time exceeds configured limits
Faults generation in application S/W
Initial High Peak current
Obstruction at Point Motor
Carbon Brushes worn out
Weak Friction Clutch
Defective Power Cable
Local data can be transferred to central location
History reports between selected dates of selected point machines
No changes necessary to the outdoor equipment
Developing integrated system for monitoring following point operations
Single Ended operations
Double Ended Serial operations
Double Ended Parallel operations
Simultaneous operations
Combinations of above operations
Benefits:
Status-orientated maintenance means less maintenance effort and hence savings in human and material resources.
Early recognition and clearing of faults reduce the number of delays considerably
A long-term evaluation of history data is possible.
