Geosense has announced that it has gained approval from London Underground for use of its Wi-SOS 480 range of wireless data acquisition equipment in deep tube tunnels.
The systems comprises a central gateway and individual nodes (dataloggers) which can be connected to a wide range of sensors measuring tilt, pressure, load and displacement. The data is sent via long-range 868MHz radio to the gateway where it can be accessed or forwarded for data visualisation.
The firm worked with its partner Worldsensing to gain the approval and Geosense has said that the achievement will open up the benefits of the system to all London Underground projects.
Under the approvals process, the Wi-SOS 480 system passed London Underground’s requirements for fire safety and electromagnetic compatibility and minimises cable runs for asset monitoring of tunnels and shafts.
“This certificate is proof of the high quality standards we aim to meet,” said Woldsensing CEO and co-founder Ignasi Vilajosana. “It shows that our products and services pass through rigorous tests and evaluation before being deployed in real scenarios.
“We don’t just produce wireless data nodes that can be connected to sensors in harsh environments, we help our clients to ensure the safety of metro passengers and underground tunnel personnel through real-time, wireless monitoring.”
Geosense managing director Martin Clegg said: “We are very pleased to have received LUL approval for the Wi-SOS equipment. It has been a long time in the making, but we are very grateful for the support from Worldsensing during the approval process.”
