Wireless Bridge Monitoring
New York may be the first state with a 24/7 wireless bridge monitoring system, reports EE Times. The $500,000 project is being funded by the New York State Energy and Research Development Authority. Engineering professor Kerop Janoyan at Clarkson University is working with TransTech Systems (Schenectady, N.Y.) to craft a commercial version of their wireless bridge monitoring system.
The wireless sensor nodes use accelerometers and strain gauges as well as more exotic sensors from ultra sound to eddy currents, depending on specific monitoring problems. Wireless nodes, which are battery powered, are polled by a master single-board computer that aggregates sensor data and determines whether to alert inspectors.
