Description

Technical Field

[0001] The present application relates to the field of bridge monitoring technology, and in particular to a multi-dimensional bridge monitoring system based on Beidou technology. Background Art

[0002] Bridges are affected by many factors during use, such as climate, oxidation, corrosion and other environmental factors, as well as long-term damage under constant load, live load and special load (earthquake, typhoon, car collision, explosion, etc.), which affect the service life and pose safety risks. Therefore, it is necessary to study bridge monitoring technology.

[0003] In the prior art, Chinese patent CN212807546U discloses a bridge dislocation monitoring device based on Beidou positioning, including a positioning measuring point mechanism, a Beidou satellite and a monitoring host. The positioning measuring point mechanism is fixedly installed on the bridge. When installing the positioning measuring point mechanism, the length of the plug-in board inserted into the plug-in interface is adjusted according to the thickness of the bridge side guardrail, so as to adjust the distance between the first clamping plate and the second clamping plate, and fixed installation is performed so that the positioning measuring point mechanism can be installed on bridge side guardrails of different thicknesses; the Beidou satellite transmits the positioning information of the Beidou positioning antenna to the monitoring host, and the data extraction module of the monitoring host extracts the previous bridge positioning data stored in the data storage module and transmits it to the analysis and comparison module. The analysis and comparison module analyzes and compares the new bridge positioning data with the previous bridge positioning data to monitor the side dislocation of the bridge.

[0004] Bridge monitoring generally involves multi-dimensional bridge information such as strain, vibration, displacement, temperature, tilt, internal cracks, laser scanning images, etc. These bridge information often correspond to different monitoring devices and different bridge locations. When the communication of one or several monitoring devices fluctuates, the above-mentioned existing technologies cannot guarantee the successful transmission of the corresponding bridge information, and the transmission reliability of bridge information is poor. In addition, when there are many types of bridge information that need to be monitored, the existing technology needs to deploy multiple sensors separately, which makes sensor deployment difficult.
