BeanAir wireless sensor network

Structural health monitoring systems are used to detect damage in buildings, bridges, ships and aircraft. These systems consist of a device that collects and stores vibration measurements from a small number of sensors, which monitor structural response to ambient vibration (wind, passing vehicles) or forced excitation.

Wireless sensor networks are a natural candidate for structural health monitoring systems, as they simplify deployment of instrumentation caused by power and wiring constraints. This can cause significant set-up delays and limit the number and location of sensors.

The BeanAir wireless sensor network (WSN) enables real-time monitoring of performance and environment. An integrated system allows BeanGateway (data collecting via Ethernet or Modbus)/BeanDevice (wireless sensors including accelerometers, inclinometers and temperature, humidity and light sensors) to operate without an internal battery.

The use of WSNs on oil and gas platforms focuses on monitoring the production process to either prevent or detect health and safety issues or to optimise and increase production. The wireless can be used to monitor remote pipelines, corrosion, equipment condition, real-time reservoir status and so on.
