Building (structure) deformation, displacement and damage cluster imaging Internet-of-Things monitoring method

Abstract

The invention discloses a building (structure) deformation, displacement and damage cluster imaging Internet-of-Things monitoring method. The principle is as follows: an initial reference point is established outside an observation structure, the deformation of a next monitoring point is observed by means of the initial reference point, and the deformation of a subsequent group of monitoring points is observed by taking the monitoring point as a first transfer reference point after the relative displacement of the monitoring point is amended; the deformation of a further subsequent group of monitoring points is observed by taking one monitoring point in the above group as a second transfer reference point after the relative displacement of the above group of monitoring points is amended; and the reference points transfer to each other sequentially in a similar way to realize clustering observation. According to the invention, in a monitoring information transfer and amendment manner, cluster Internet-of-Things monitoring is realized with the advantages of higher speed and higher efficiency; imaging devices and grating scales are installed at one time to reduce errors in the monitoring process; and a certain point on a monitored object can be directly selected as a monitoring point without the installation of a grating scale, thereby realizing monitoring of an unapproachable building (structure).

Description

technical field [0001] The invention relates to the deformation monitoring of existing and under-construction (structure) structures, mainly in the technical fields of settlement deformation monitoring, horizontal displacement monitoring and appearance damage development monitoring. Background technique [0002] With the increase of built and under-constructed (buildings) and the high incidence of building collapses in recent years, the safety monitoring and reliability evaluation of buildings have been paid more and more attention. The national "Thirteenth Five-Year Plan" research group will also establish key technologies for reliability evaluation and life-span evaluation of existing industrial building structures as a special topic. The deformation monitoring and measurement of buildings is particularly important in building reliability evaluation. At present, the common means of building deformation monitoring is to use measuring instruments such as theodolite, level, ...

AI Technical Summary

Problems solved by technology

Among them, GPS has the advantages of all-weather, high speed, automation, no need to communicate between stations, can measure three-dimensional coordinates at the same time, and has high precision. However, GPS receivers are greatly affected by satellite signals being blocked and multi-path effects; Low, unable to achieve dynamic micro-deformation monitoring, and there are many sources of data errors, making the data difficult to process

At present, both monitoring methods have the disadvantages of high cost and unguaranteed monitoring accuracy.
