Clustered-type bridge health real-time monitoring system and method based on wireless communication technology

Abstract

The invention provides a clustered-type bridge health real-time monitoring system based on wireless communication technology. The system comprises bridge heath state data collecting and processing subsystems arranged on all bridges and a bridge heath real-time monitoring center which is arranged at a background and is used for receiving bridge health monitoring data uploaded by the bridge heath state data collecting and processing subsystems, thereby obtaining the heath state evaluation, comparison and life forecast as well as bridge maintaining and tending strategies; and each subsystem performs data transmission with the bridge heath real-time monitoring center in a wireless mode. According to the system, the bridge heath state data collecting and processing subsystem is installed on a specific bridge, the bridge heath real-time monitoring center is installed at the background, and the data transmission between the subsystem and the bridge heath real-time monitoring center is realized by adopting the wireless communication technology, thus the construction difficulty and cost are reduced, and the arrangement of monitoring points is more flexible.

Description

technical field [0001] The invention relates to the technical field of bridge health real-time monitoring, in particular to a clustered bridge health real-time monitoring system and method based on wireless communication technology. Background technique [0002] With the rapid development of transportation, the importance of various large bridges in traffic engineering has become increasingly prominent. At present, many bridges that have been built have entered the stage of maintenance and repair, and 40% of the total number of bridges in our country are already "old" bridges. Sudden and catastrophic accidents on domestic bridges are increasing day by day, causing serious losses to people's lives and property. In order to prevent the occurrence of catastrophic events, systematic monitoring of large bridges to realize prediction and forecast accidents and prevent disasters has become a major issue in ensuring traffic safety. [0003] For a long time, the safety detection of...

AI Technical Summary

Problems solved by technology

[0005] At present, large-scale bridge health monitoring systems at home and abroad mostly collect and detect data for a single bridge. Due to the large number of measurement points and scattered distribution, they are far away from each other, and the data transmission is mostly completed through wired networks. Not only the installation and wiring are troublesome, but also the cost is high. , and it is also difficult to simultaneously monitor the health status of multiple large bridges (bridge clusters)
