Study on Remote Vibration State Monitoring System for Bridges

A remote vibration data monitoring system was developed according to the requirement and the characteristics of the bridge vibration monitoring. This system includes three key parts, namely, local network data acquiring module, remote transmission module and remote monitoring center module. It can collect the vibration state parameters of bridges according to presetting period and triggering condition. The host computer of the remote monitoring center can process the data and show the results of monitoring via network. Vibration data network acquiring module was realized in this system. Being installed in the steel bridge for nearly three years, the system has run well and fulfilled the expectant goals very well. The results show that the system is excellent in the many aspects, such as strong timeliness, high reliability and accuracy, transplantation and so on. The design of the whole system, the performance of software and hardware and the functions of the system have been described in detail in this paper. And the system can be referenced by other remote monitoring systems such as dams, road bridges and huge architectures etc.
