Innovative vibration sensors provide curve detection and derailment protection for trains

摘要

Micro-Sensor recently supplied curve detection systems for use on high-speed trains for the Haramain High-Speed Rail Project in Saudi Arabia. These high-speed electric passenger trains travel at speeds of up to 300 km/h across a 453 km network between Medina and Mecca. For high-speed trains that travel at speeds in excess of 160 km/h, European rail industry regulations stipulate that these trains must be fitted with suitable derailment safety protection systems. High vibrations resulting from the interactions between the train and the track can potentially cause a carriage to derail. For the Haramain High-Speed Rail Project, Micro-Sensor supplied bogie-mounted vibration sensors for improved derailment protection and curve detection systems to monitor carriage/wagon tilt in curves, for better control of the lubrication of the wheels during curves in the track.
