Using a system supplied by Frauscher, a fiber-optic cable is laid along the line, which uses rail defectoscopy to detect cracks or breaks in the rail by picking up the vibrations produced by the train passing by.
Acoustic Sensing - A train’s vibration pattern as it progresses its journey is picked up by lineside sensing equipment, usually a fiber optic cable....Installations exist worldwide, including on Network Rail and London Underground.
Fiber optic sensors, which work on the basis of Distributed Acoustic Sensing (DAS), provide comprehensive access to a wide range of information surrounding the railway....These solutions allow an overview of the entire railway network, including rolling stock, to be formed in real-time.
Over several years, Frauscher has supplied various projects in Taiwan with innovative, tailored solutions – based on their product’s unique capabilities
Dr. Chris Minto, Engineering Director of member company OptaSense, will present “Towards 1 Billion Sensors: Distributed Fiber Sensing as a Pervasive IoT Contributor” on behalf of FOSA during this week’s Optical Networking and Communication Conference (OFC) in San Diego, California.
