Bridge vibration monitoring system based on vibrating-wire sensor and ZigBee technologies

摘要

A bridge vibration monitoring device with the vibrating-wire sensor as the basic measuring device is designed to solve some problems in the application of the traditional engineering vibration measuring technologies into bridge monitoring, and a remote monitoring system is established with the wireless network technology, with hardware and software design integrating the single chip, ZigBee and GPRS. The monitoring data is aggregated to the coordinator node via wireless communication and is finally transmitted to the host computer through GPRS module. It is indicated in site applications that the system has such advantages as strong instantaneity, high reliability and easy networking, and can be preferably applied for the remote monitoring of health conditions of dams, highway bridges and other large building structures.
