A long-span bridge health status monitoring device

Abstract

The invention discloses a health state monitoring device for a long-span bridge, and the device comprises (1) a video collection terminal which is used for collecting a video comprising tracking targets through a high-speed camera, wherein the tracking targets are the dangerous parts of the bridge; (2) a server which is used for receiving the video collected by the video collection terminal, extracting a video image and storing the video image in a database; (3) a client which is used for carrying out the processing, analysis and displaying of the video image in the database, so as to achieve the remote real-time monitoring and health evaluation of the health condition of each bridge. Through the setting of the video collection terminal, the server, the client and early-warning equipment, the device achieves the real-time and objective intelligent evaluation and early-warning of the health conditions of the bridge, and is high in automation degree. Moreover, the client can carry out the inspection of the data in the server through the Internet, and the client can be set flexibly.

Description

Technical field [0001] The invention relates to the field of building health monitoring, in particular to a large-span bridge health status monitoring device. Background technique [0002] At present, middle-aged and old bridges account for a considerable proportion of the domestic land transportation network. With the growth of bridge age, due to the effect of natural factors such as environment and climate, there is an increasing traffic volume and the number of heavy and overweight vehicles crossing the bridge. Due to factors such as increasing and man-made accidents, many bridges have experienced serious functional degradation. Therefore, it is necessary to monitor the health of the bridges and carry out necessary maintenance to prevent the occurrence of disasters such as bridge collapse. [0003] In related technologies, bridge monitoring methods include manual monitoring methods, that is, manually measuring, recording, and processing various data on the health of the bridge. ...

AI Technical Summary

Problems solved by technology

[0003] In related technologies, bridge monitoring methods include manual monitoring methods, that is, to manually measure, record and process various data of bridge health status. The consistency of the working status of the point data, and it is inevitable to introduce human errors in the process of data measurement, recording, and processing. Furthermore, due to the geographical distribution of bridges, it is also difficult to manually monitor

In addition, during monitoring, modern optical, ultrasonic, electromagnetic and other technical detection tools are generally used to detect the mechanical properties and working performance of large structures, which can only provide local detection and diagnostic information of the structure, but cannot provide overall and Comprehensive full-bridge structural health monitoring and assessment
