Problems solved by technology

[0003] However, due to the influence of the manufacturing process or the influence of the installation error of the inclinometer tube, the orientation of the slot at the mouth of the inclinometer tube may not be consistent with the orientation of the slot at the bottom of the tube. When calculating the displacement value of the bottom of the inclinometer pipe with the azimuth of the card slot at the mouth, there will be a large error, which will cause great losses to geotechnical engineering
Therefore, the measurement method of the inclinometer still needs to be optimized

Embodiment Construction

[0044] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0045] In the field of geotechnical engineering, inclinometers are often used for deep displacement monitoring of geotechnical engineering such as foundation pits, landslides, dams, and foundations. The inclinometer is an in-situ monitoring instrument that obtains the horizontal displacement by measuring the inclination angle of the borehole. Such as figure 1 As shown, the conventionally used portable inclinometer is equipped with an inclination sensor on the main body, and guide wheels are installed on both sides of the main body. At the measurement position, the inclination sensor on the inclinometer uses the principle that the plumb bob is affected by gravity to measure the angle between the axis of the inclinometer tube and the plumb line at different measurement positions of the inclinometer tube, and then calculate the angle according to the me...

Abstract

The invention discloses a displacement measurement method and device, an inclinometer and a computer storage medium. The method comprises the following steps: acquiring two pieces of inclination angledata and two pieces of direction angle data obtained when an inclination angle sensor and a magnetoresistive sensor on the inclinometer perform measurement along a first direction and a second direction respectively for each measurement position in a plurality of measurement positions of an inclinometer tube; determining the inclination length of a section of inclinometer pipe corresponding to the corresponding measurement position in a first coordinate system according to the obtained two inclination angle data; determining a direction angle of a section of inclinometer pipe corresponding tothe corresponding measurement position in a first coordinate system according to the two obtained inclination angle data and the two obtained direction angle data; and determining the displacement value of the inclinometer pipe according to the inclination length and the direction angle corresponding to each section of inclinometer pipe.

Description

technical field [0001] The invention relates to the field of geotechnical engineering measurement, in particular to a displacement measurement method, device, inclinometer and computer storage medium. Background technique [0002] The inclinometer is a kind of measuring equipment used to measure boreholes, foundation pits, foundations and walls, etc., and is widely used in the construction industry. When measuring the displacement, the inclinometer is placed in the inclinometer tube, and fixed by the guide wheel of the inclinometer and the slot in the inclinometer tube. When measuring the displacement, the usual method is to measure the angle between the axis of the inclinometer tube and the plumb line, and use the measured angle to measure the displacement value of the land where the inclinometer tube is buried. [0003] However, due to the influence of the manufacturing process or the influence of the installation error of the inclinometer tube, the orientation of the slo...
