Grip displacement testing system and method based on ten-shaft sensor

Abstract

The invention provides a grid displacement testing system and method based on a ten-shaft sensor. The grid displacement testing method comprises the steps that a ten-shaft sensor chip is embedded intoa geogrid; the ten-shaft sensor chip acquires data information of a monitoring point and uploads the data information to a monitoring cloud management platform; the monitoring cloud management platform obtains geogrid deformation amount and displacement change of the monitoring point through comprehensive analysis according to the acquired data information, conducts error correction processing onthe data information, reduces data error rate and improves data integrity rate; the monitoring cloud management platform synchronously updates the data information acquired by the ten-shaft sensor chip and analysis results to a monitoring database server; a remote monitoring center extracts data in the monitoring database server, obtains the width and extension trend of cracks produced by a wholestructure of the geogrid after further processing, monitors the overall damage trend of the geogrid in real time and finally achieves automatic monitoring of the overall state of the geogrid and early warning of geological disasters.

Description

technical field [0001] The present disclosure relates to the technical field of civil engineering monitoring, in particular to a grid displacement testing system and method based on a ten-axis sensor. Background technique [0002] In recent years, geological disasters have occurred frequently, which have had a great impact on people's lives and safety, not only causing damage to engineering facilities, but also bringing huge economic losses. Therefore, appropriate preventive measures for geological disasters should be taken to minimize geological Minimize the losses caused by disasters. At present, most of the engineering projects focus on strengthening the areas that may be damaged according to the construction experience and engineering practice. Due to the differences in various factors such as topography, geology, and environment, there is a lack of uniform criteria for determining the areas that may be damaged. Factors have a great influence, and judgment bias may occu...

Problems solved by technology

[0005] In existing projects, there is a method of binding geogrids and strain sensing fiber gratings together to measure their deformation and force. However, this method is easy to loose due to the binding method. Once loose, it will not be able to accurately capture and transmit strain, resulting in large errors in the obtained data. At the same time, this method is limited by its material, and can only measure large deformations, and small strains cannot be accurately captured. The purpose of taking corresponding measures in a timely manner

[0006] To sum up, for the visual test and prediction of structural damage caused by geological disasters, and there is no overall monitoring management and early warning system for geological disasters after geological disasters damage structures
