摘　　要：针对大佛寺长江大桥的实际情况和具体要求进行了远程状态监测系统的开发,该系统包括现场监测子系统和远程监测子系统。现场监测子系统可以通过安装在桥梁关键部位的光纤应变传感器、光电连通管式挠度传感器、温度传感器等获得桥梁的状态信息并存储,还可以通过光缆将信息传输到远程监测子系统以供分析桥梁的安全状态。整个系统已于2002年底安装在大佛寺长江大桥上。A state remote monitoring system is designed for Dafosi Bridge over Yangtze River. This system includes two subsystems, namely, local computer subsystem and remote monitoring computer subsystem. The local computer subsystem can gain the state informations of the bridge via sensors, which installed in the key parts of the bridge, such as the fiber-optic strain sensors, the photocell type deflection sensors and the temperature sensors. It also can store and transmit the state information via fiber optic cable to the remote monitoring computer to analyze and evaluate the health state of this bridge. This system was installed in the bridge in the end of 2002.
