Smart Overhead Line Monitoring System (SOLMS)
(REF: S-1466) |
| Trial Project |
|
| Solution Feature |
- Smart Overhead Line Monitoring System employs fibre-optic FBG sensors made of glass, which is an excellent electrical insulator, and the optical sensing signals are interrogated by light. The optical signal is highly accurate and exhibits excellent signal-to-noise ratio that is immune to EMI even in high voltage environment.
- Co-development of innovative technology by team formed by government, university and industry. Technology based on local developed, Government owned intellectual property will be employed in the design of FBG sensor assembly. SOLMS adopts a small size and low power consumption FBG interrogation unit that is developed by PolyU academics.
- SOLMS monitors both static and dynamic behavior of critical components of OHL system, therefore both hidden and impending defects of mechanical components can be identified. Contact performance between feeding wires and pantograph of train could potentially be characterized. This type of comprehensive platform is not available in the market.
- The SOLMS adopts advanced artificial intelligence algorithms that perform essential data processing and analysis to enable rapid, real-time analysis and response with high reliability. Availability of prognostic tools developed by this monitoring system also enables the current maintenance strategy migrated from routine and condition-based to predictive and proactive-based.
- System Upgradability – application of optical fibre sensing technology allows the monitoring system be upgraded to monitor other critical OHL components and extend the coverage of OHL monitoring.

| Trial Application and Expected Outcome |
- An innovative monitoring system based on optical fibre sensing technology for long-term continuous monitoring of health condition of railway overhead line system will be developed. The system consists of two types of specially designed fiber Bragg grating sensors and a 5G enabled, customized data processing unit.
- Optical fibre sensor based on patented design for monitoring the tension applied by the balance weight anchor (BWA) of the OHL system will be developed. The sensor is also able to evaluate the dynamic response of the automatic tension mechanism.
- Optical fibre sensor assembly for measuring concurrently the vertical vibration, tensile load and temperature of catenary and contact wires of OHL system will be developed. Dynamic behavior of the interaction between the wires with respect to passing trains can be correlated with the tension measurement of the BWA.
- A 5G enabled, customized data processing unit for sensor interrogation, data processing and warning signal generation and remote reporting via 5G mobile network will be designed in this project.
- Artificial intelligence and machine learning decision algorithms will be developed after the data collection period. The collected data will be categorized and further employed to train up the algorithms, these algorithms will then be installed into the data processing unit.
