Remote Diagnostic
& Predictive Maintenance
For Signalling Gears
Remote Diagnostics and Predictive Maintenance Systems for railway signaling continuously monitor the health of key assets like signals, point machines, track circuits, LC gates, power supply, electronic interlockings, and cables. Using sensors and IoT technology, the system detects early signs of issues, allowing maintenance teams to address problems before they cause major disruptions.
By analyzing historical data, these systems can predict future failures in signaling components, optimizing maintenance schedules and reducing downtime. This proactive approach improves the safety and reliability of railway operations, extending the lifespan of critical equipment and infrastructure.
Architecture
It uses sensors to collect data from railway gears, which is transmitted via Zigbee, LoRa, or 4G to an edge gateway and then processed on cloud servers. The system’s AI and ML algorithms analyze this data to predict failures, generate alerts, and suggest maintenance actions.
Its scalable, modular design ensures high availability and easy installation.
Applications
RDPMS for the signaling system is specifically designed for Signal & Telecommunication (S&T) with extensive research. It offers real-time monitoring, fault detection, and predictive maintenance for railway signaling assets, improving operational efficiency.
Point Machine
Monitors operating voltage, current, and machine signatures to detect obstruction or abnormal operations.
Signal
Tracks aspect voltage and relay status, identifying faults like signal blanking or cable degradation.
DC Track Circuit
Analyzes voltage and current to detect track occupancy, resistance issues, and outdoor relay failures.
Battery Health
Monitors each cell's voltage, charging/discharging current, and predicts battery life.
LC Gate
Detects gate status, motor voltage, and operational anomalies such as improper boom closure.
Axle Counter
Monitors relay status and voltage, detecting unit errors and axle counter failures.
Signaling Cable
Identifies cable faults, earth leakage, and degradation based on bus voltage.
Power Supply
Monitors power input and output voltages to ensure stable operation of signaling systems.
