Design and Implementation of a Wireless Bridge Health Information Acquisition Node

A wireless bridge health information concentration acquisition system based on ZigBee is proposed in this paper. It can be used for bridge health information collected, to provide an efficient data for bridge protection. The monitor system includes acquisition node and receiving equipment. In actual use, the acquisition node was designated deployment, through specific deployment device. The data that collected by acquisition node can be transported through ZigBee networks, receiving equipments get it, then transmission and storage. The node working principle, hardware and software development of acquisition node has been carried in this paper. The acquisition node is designed by the CC2430 processor plus RF and developed on IAR EW development environment and Z-stack operating system. In actual environment, a series of test indicated that the system could provide the effective, reliable and real-time nature for wireless collection of bridge health information.
