多传感器远程桥梁监测技术研究

Research on Bridge Detection with Sensors in Long- Distance

本文通过试验验证了一种新的桥梁监测方法，利用PXI和SCXI总线技术搭建测量平台，用虚拟仪器软件LabVIEW编程，用Measurement ＆ Automation Explorer软件采集处理信号，模拟在不同荷载、不同车速条件下桥梁应变、挠度和振动状态的变化情况，进行桥梁的动静载测试试验，分析信号的变化情况，实现对桥梁的健康监测。

This paper presents a new method of bridge detection through the experiment. Bulids a measuring platform with PXI and SCXI virtual instruments, programmes with a software named LabVIEW, gathers and deals sig- nals with Measurement＆Automation Explorer software. The system can simulate the situation of bridges under different press and speed of cars. Then we can realize the situation of bridges after analyzing the changing signals from the system.
