为中国西部长江上最大的斜拉桥大佛寺大桥设计并安装了健康监测系统。本文简要介绍了在线偏转监测系统，它是健康监测系统中最重要的传感子系统。它可以分为两个主要部分，一个用于测量，一个用于控制和数据处理。测量系统本身包括两种挠度传感器，用于监测两座塔的横向位移和主梁的弯扭位移。传感器输出在本地进行预处理，并通过互联网发送至管理中心上位机。回顾了系统的设计和实现，并给出了两种传感器的数据结果。
A health monitoring system was designed and installed on Dafosi Bridge, the largest cable-stayed bridge across the Yangtze River in western China. This article briefly describes an online deflection monitoring system, the most important sensing subsystem of the health monitoring system. It can be divided into two major components, one for measurement, and one for control and data processing. The measurement system itself includes two types of deflection sensors to monitor the lateral displacement of the two towers and the flexural and torsional displacement of the main girder. Sensor outputs are pre-processed locally and sent to the host computer at the management center via the Internet. The system design and implementation are reviewed, and the results of data from two kinds of sensors are presented.
