Predictive Maintenance Railway Monitoring System Based on Optical Fibre Sensing

【知識轉移，改變世界】鐵路是城市的脈絡，要穩定可靠的鐵路服務，要龐大的人力、資源與技術維護，才能讓我們享受準時又安全的列車服務。

#理大 電機工程學系光子學講座教授譚華耀教授憑著其團隊在光纖技術方面15年的研究成果，開發出世上首個光纖鐵路監測系統。此創新系統透過傳感器實時監測路軌、列車和轉向架狀況，並偵測路軌上過度或異常的振動，以預先識別潛在故障。譚教授的鐵路監控系統已安裝於香港和新加坡的鐵路系統，為 880 萬乘客提供更順暢的旅程。

譚教授的光纖鐵路監測系統改善了鐵路檢修流程，是理大十項獲得「校長特設傑出成就獎 (知識轉移)」的得獎研究之一。

【Knowledge Transfer for a Better World】Railways are the veins of a city, its lifeblood, transporting and connecting us to different communities and activities in a thriving metropolis. Much like the functioning of our own vascular system, the railway service is often taken for granted — we just expect it to work no matter what. In reality, it requires considerable manpower, resources and technology to maintain, just so we can enjoy timely and safe train services.

Prof. Tam Hwa-yaw, Chair Professor of Photonics from #PolyU’s Department of Electrical Engineering leveraged his team’s 15 years of research in optical fibres technologies to develop the world’s first integrated optical fibre-based railway monitoring system. This innovative system monitors the real-time conditions of tracks, train cars and bogies through sensors, and picks up any excessive and abnormal vibrations on a rail track in order to identify potential faults. Prof. Tam’s railway monitoring system has been installed in the metro systems in Hong Kong and Singapore, making journeys smoother for 8.8 million passengers.

Prof. Tam’s integrated optical fibre-based railway monitoring system streamlines and improves railway maintenance, and is one of ten impactful PolyU projects to be awarded the “President’s Awards for Outstanding Achievement in Knowledge Transfer”.
