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.
