Method and system for building structure deformation monitoring based on Beidou satellite

Abstract

The invention discloses a method and a system for building structure deformation monitoring based on a Beidou satellite. The system comprises an existing Beidou satellite. Monitoring base stations are mounted at measured points of a building structure, and a datum station is arranged in a relatively non-settling area near the building structure. Beidou satellite modules which can receive the positioning signal of the Beidou satellite are arranged in the monitoring base stations and the datum station. The monitoring base stations and the datum station transmit the positioning signal to a terminal service system through a wireless signal transmitting system. The terminal service system is composed of a signal receiving system, a data processing and analyzing system and an early warning system. By using the method and the system, long-term, real-time and automatic monitoring can be carried out on the deformation of the building structure, and automatic processing, analyzing and early warning can be carried out on monitoring data. The method and the system are of great significance to preventing accidents caused by over-range deformation of the building structure.

Description

technical field [0001] The invention relates to a method and system for monitoring building structure deformation based on Beidou satellites, and belongs to the technical field of building structure deformation monitoring. Background technique [0002] During the service of building structures for decades or even hundreds of years, the coupling effects of environmental erosion, material aging and load effects, man-made or natural mutation effects and other disaster factors will inevitably lead to the accumulation of building damage and damage. The resistance attenuation reduces the ability to resist natural disasters, normal loads and environmental effects, causing catastrophic accidents. Once the damage of the key components of the structure accumulates to a certain extent, if it is not discovered and dealt with in time, the damage will expand rapidly, leading to the destruction of the entire building, resulting in inestimable property losses and casualties. In order to pr...

Once the damage of the key components of the structure accumulates to a certain extent, if it is not discovered and treated in time, the damage will expand rapidly, leading to the destruction of the entire building, resulting in inestimable property losses and casualties

In order to prevent the occurrence of the above accidents, the traditional monitoring of building structure deformation is to use total station, level and other artificial regular monitoring. The accuracy is affected by the monitoring equipment and the experience of monitoring personnel, and it cannot be monitored in real time.

Therefore, the existing methods for monitoring deformation of building structures are still not ideal.
