摘要 介绍了大佛寺桥的健康监测系统,该健康监测系统由本地子系统和远程监测子系统构成。其中本地子系统包括:(1)光纤应变传感子系统,(2)挠度位移测量子系统,(3)温度传感子系统,(4)动力学测量子系统等四个传感子系统及本地控制和数据处理子系统:而远程监测子系统则包含通信与传输子系统以及远程服务器群等;监测结果通过Internet传送到远端的管理中心。介绍了静态参数监测系统的设计、实施,并给出了各传感子系统的部分监测结果。 The Dafosi Yangtze River Bridge is the largest cable - stayed bridge across the Yangtze River in the western China. In the paper, a health monitoring system for this bridge is briefly described. The system can be divided into a local system and a remote monitoring system. The local system includes a local control and data processing subsystem and four sensing subsystems (1) fiber optic stain sensing subsystem, (2) displacement sensing subsystem, (3) temperature sensing subsystem, (4) dynamic measurement subsystem. The remote monitoring system consists a communication subsystem and host servers. The monitoring data is sent to a management center via the lnternet. The system design and implementation of static measurment are introduced, and the monitoring results of the sensing subsystems presented.
