Fixed type grating-shape capacitive coder inclinometry device, inclinometer, inclinometry equipment and inclinometry system

Abstract

The invention relates to a fixed type grating-shape capacitive coder inclinometry device, an inclinometer, inclinometry equipment and a inclinometry system. The inclinometry device and the inclinometer use a grating-shape capacitive coder principle, the angle of inclination of the device is measured, then the offset of the inside of a measured soil layer is calculated, and therefore, the fixed type grating-shape capacitive coder inclinometry device and the inclinometer have high detection precision under relatively low cost. According to the inclinometry equipment, a plurality of inclinometers are fixedly mounted in a guide tube, the circumstance that the inclinometers are manually operated to ascend and descend in the guide tube is avoided, and automated real-time continuous measurement can be realized on the premise of low integral cost and high measurement precision. By the inclinometry system, remote or local interaction can be realized, data are read conveniently, and the safety is high.

Description

technical field [0001] The invention relates to a fixed capacitance grid encoder inclinometer device, inclinometer, inclinometer equipment and inclinometer system. Background technique [0002] In the construction monitoring of subways and large buildings, and in the protective monitoring of dam bridge slopes, inclination measurement is a very important indicator. The inclinometer measures the offset change caused by the internal displacement of the soil, and can draw the displacement section diagram of the measured section. By analyzing the data obtained from daily measurements, it is possible to deduce the change trend of the internal soil, guide engineering construction, monitor structural conditions, and prevent disasters such as landslides and landslides. [0003] At present, the sliding gravity acceleration sensor inclinometer is mostly used. The sliding inclinometer is put into the bottom of the measured inclinometer first, assuming that the bottom of the hole does n...

AI Technical Summary

Problems solved by technology

However, the inclinometers currently used have the following problems: 1. Due to the use of low-cost acceleration sensor chips, the accuracy is low, and its accuracy barely meets the requirements; 2. The cost is still high and cannot accept a large number of high-density applications; 3. There are many and complicated lines, and the installation and arrangement are troublesome
