The optical fibre technology developed by PolyU has been installed in the nation’s High-Speed Rail with a view to further enhancing its structural health and safety. Key members of the research team include Prof. Ho Siu-lau, Prof. Tam Hwa-yaw and Dr Michael Liu of the Department of Electrical Engineering; Profs. Ni Yiqing and Yin Jianhua of the Department of Civil and Structural Engineering; Profs. Zhou Limin and Cheng Li of the Department of Mechanical Engineering; and Dr Wang Dan of the Department of Computing.

The PolyU-developed and award-winning “Advanced Fibre Bragg Grating Railway Monitoring System” has been installed in major parts of the Beijing-Shanghai High-Speed Rail to gather real-time data on vibration, acceleration and temperature change, which will then be used for monitoring the condition of tracks and railcars as well as structural health of the rail foundation.

Working closely with Dalian Jiaotong University, PolyU-developed optical sensors have been installed in high-speed inspection trains for monitoring purpose. Also, the University is collaborating with Southwest Jiaotong University to monitor the settlement of rail foundation with the use of specially-developed optical sensors. Details>>
