Design of a Monitoring System of Airport Boarding Bridge Based on ZigBee Wireless Network

In order to overcome the disadvantages of boarding bridge's collapse and scraping the plane without early warning, a design of wireless fault early warning and monitoring system combining ZigBee wireless communication technology and variable sensors which are used to detect vibration, position, and faults, was proposed. The structure of network, the design of hardware and the software modules of the monitoring system are discussed in detail. Experiments show that the application of wireless ZigBee technique with low cost and low-power dissipation makes the monitoring system of airport boarding bridge more flexible and shortens the troubleshooting time. Besides, it could eliminate the cumbersome problem of overall fault diagnosis on site.
