Dangerous and old building monitoring system based on Beidou positioning technology and dangerous and old building monitoring method based on Beidou positioning technology

Abstract

The invention discloses a dangerous and old building monitoring system based on the Beidou positioning technology. The dangerous and old building monitoring system comprises a, an inclination and settlement monitoring module which is used for extracting the inclination characteristic quantity of the monitored house building in real time; b, a crack monitoring module which is used for monitoring the crack width of the monitored house building in real time; c, a stress-strain monitoring module which is used for performing real-time stress-strain characteristic quantity monitoring on the monitored house building; d, a dynamic characteristic monitoring module which is used for monitoring the change of the dynamic characteristic after internal damage of the monitored house building; e, an information processing module which is used for receiving the monitoring data outputted by the inclination and settlement monitoring module, the crack monitoring module, the stress-strain monitoring moduleand the dynamic characteristic monitoring module; f, a BDS positioning system; g, an auxiliary monitoring module; h, a central processing module; i, an intelligent analysis cloud platform; and j, a client side module. The advantages are that safety warning of the dangerous and old building can be realized.

Description

technical field [0001] The invention relates to the field of building monitoring, in particular to a system and method for monitoring dangerous old buildings based on Beidou positioning technology. Background technique [0002] In the early development and construction of our country, most of the houses were masonry and concrete structures. Due to their long service life, there were many potential safety hazards; and most of the small and medium-sized cities had poor information infrastructure, and the early projects were in the process of planning, design and construction. Limited by technical conditions at the time, a complete and scientific management mechanism was not established, which led to difficulties in the maintenance and management of houses in the later period. Coupled with the constraints of economic and other factors, such dilapidated houses are still used in operation. [0003] According to the research and analysis of many cases of house collapse accidents, ...

AI Technical Summary

Problems solved by technology

First of all, the traditional method cannot achieve 24h uninterrupted monitoring, and only conducts periodic partial detection of the building structure, such as the rebound method, shock echo method, ray method, etc. The randomness of the random inspection data is very large and the representativeness is insufficient. It is conducive to the accurate analysis of the later results, and it is easy to lead to no basis for the settlement of the workload in the later stage of the project; secondly, the traditional method requires a lot of manpower and material resources, the cost is high, and the detection efficiency is low. At the same time, the technical level and experience of the testing personnel are also required. , and the human factors in the detection results are relatively large, which may easily lead to untimely early warning
