A monitoring system and method for micro-displacement deformation based on tension sensor

Abstract

The invention discloses a miniature displacement deformation monitoring system and method based on a tension sensor, and the system comprises the tension sensor, a spring, a steel wire, a communication device, and a power supply device. The system calculates the precise spring deformation through the real-time obtaining of the high-precision tension data and a known spring tension coefficient, andcarries out the inversion of the geometric deformation of the ground objects. The system can achieve the long-time and high-precision monitoring of the deformation of the side slope under the condition that the system employs a cheap tension sensor, is lower in cost, is simple in structure, is convenient to construct, and can achieve the long-time monitoring and early warning for the cut slope.

Description

technical field [0001] The invention belongs to the technical field of slope deformation monitoring, and relates to a tension sensor-based micro-displacement deformation monitoring system and method, which has low cost and high precision, and is suitable for long-time unmanned monitoring of cutting slopes along highways and railways. Background technique [0002] In traditional slope deformation monitoring, slope monitoring and data feedback analysis is an important link in slope engineering. Cutting slopes have the characteristics of large slopes, small ranges, and large quantities. Using GNSS satellite positioning monitoring technology at monitoring points will cost too much equipment and be easily blocked by satellite signals caused by high slopes, often failing to achieve the expected monitoring effect. ; The use of laser rangefinder and total station equipment is easily affected by severe weather such as heavy fog and the monitoring cost is also high, which cannot meet ...
