Abstract

The invention provides a structure surface deformation monitoring system. The system is used for monitoring three-dimensional surface deformation of a structure to be detected and comprises at least three microwave detectors, a data acquisition transmission unit and a remote control processing system. The at least three microwave detectors are arranged at different elevation positions respectively and forms mutual intervisibility with the structure to be detected. The invention simultaneously provides a structure surface deformation monitoring method. By using the structure surface deformation monitoring system and the method provided in the invention, static state deformation of three directions and a dynamic vibration characteristic of the structure to be detected can be simultaneously measured; an automation degree is high and continuous and real-time measurement can be achieved; and the system and the method are suitable for various kinds of demands of complex structure surface deformation monitoring.

Description

technical field [0001] The invention relates to the field of building structure safety monitoring, in particular to monitoring of building structure surface deformation. Background technique [0002] Structural safety monitoring mainly includes deformation monitoring, seepage monitoring, stress and strain monitoring, temperature monitoring, etc. Among them, deformation monitoring is intuitive and reliable, and can basically reflect the structural safety behavior under various loads, so it has become the most important monitoring item. The present invention is primarily concerned with structural surface deformation. At present, the structural surface deformation monitoring technology mainly includes: conventional geodetic surveying technology, measuring robot monitoring technology, ground three-dimensional laser scanning technology, photogrammetry and remote sensing technology, GPS technology, etc. The above surface deformation measurement technologies have more or less sho...
