Problems solved by technology

[0002] At present, one-dimensional displacement sensors are used to measure displacement in the field of civil engineering testing at home and abroad, and the displacement of the measured point is mostly generated in two directions. When using a combination of one-dimensional displacement sensors to measure two-dimensional displacement, it will A relatively large error is generated, which affects the accuracy of the output result

Abstract

This invention relates to one 2D displacement measurement method, which comprises the following steps: according to Wheatstone bridge circuit test principle to distribute the bridge resistance wire into direct or arc shape and the direct resistance wire is to test line displacement; the arc resistance wire is to test arc length change volume and then according to the relationship between arc length and radium to get test point rotary angle; through testing points in electrode coordinate displacement change to realize 2D displacement. The 2D displacement sensor comprises the test bridge line resistance wire and arc resistance wire fixed onto one structure around axis and it also comprises data transmission line.

Description

technical field [0001] The invention belongs to the field of measuring instruments, and relates to a displacement measuring device that can be used in the fields of civil engineering testing and mechanical monitoring, especially a device that can realize the measurement of the two-dimensional displacement of a measured point by a single sensor. Background technique [0002] At present, one-dimensional displacement sensors are used to measure displacement in the field of civil engineering testing at home and abroad, and the displacement of the measured point is mostly generated in two directions. When using a combination of one-dimensional displacement sensors to measure two-dimensional displacement, it will A relatively large error is generated, which affects the accuracy of the output result. Contents of the invention [0003] The purpose of the present invention is to provide a two-dimensional displacement sensor, which can accurately measure the two-dimensional displace...
