Fotech’s Distributed Acoustic Sensing (DAS) technology converts thousands of kilometres of optical fibres already in place in our cities into millions of acoustic and vibration sensors. DAS converts cables into a network of state-of-the-art sensors. This allows cities to send and receive information with the benefit of providing anonymity to its citizens, but also to monitor city infrastructure continuously – in real-time and on a much more detailed level.
Our DAS technology recognises and detects the acoustic and seismic signatures of footsteps, vehicles, trams and trains so that mobility can be improved by shorting journey times and reducing emissions leading to a better environment. Trains can be accurately tracked in real time to provide information on arrival times. Threats to infrastructure such as pipelines or power and communication cables can be detected early to prevent incidents and structures can be monitored to ensure they maintain their integrity and safety. DAS data can be used in a number of ways in our cities to improve the environment we live in, by reducing congestion, making journeys smoother, the air cleaner and enhancing our security and safety.
Cities all over the world are looking for smart technology solutions to problems such as ensuring security and safety, alleviating congestion, and locating leaking utility pipes. Many smart solutions are already in place – most of these are discrete, point sensors, often providing a partial view of the asset and usually not working together. Fotech’s DAS technology can provide continuous sensing of events along an full asset and integrate with these point sensors to complete the picture, all using fibre assets already in place, to provide the real-time insights cities need to become truly smart.
