Automatic measuring device based on laser reference plane

Abstract

The invention discloses an automatic measuring device based on a laser reference plane, which comprises a laser emitting end arranged at a reference point and a laser receiving end arranged at a to-be-measured point, wherein the laser emitting end emits a surface laser signal at the reference point, the laser receiving end intersects with the surface laser signal at the to-be-measured point, and the laser receiving end is used for analyzing a laser signal and sending an analysis result to the laser emitting end. The device can accurately measure the displacement and achieve large-scale synchronous data acquisition on a target in a large range.

Description

technical field [0001] The invention belongs to the technical field of displacement measurement, in particular to an automatic measurement device based on a laser reference plane. Background technique [0002] In the prior art, there are many ways to measure displacement, and various displacement sensors, measuring robots or total stations are usually used for manual measurement. However, whether it is a measuring robot or a high-precision displacement sensor, it can only obtain displacement monitoring data at a specified position. If more data needs to be obtained, it is often necessary to increase the number of displacement sensors or increase the number of measuring points to achieve. However, in practical engineering applications, the increase in the amount of data at monitoring locations will often lead to an increase in measurement costs. Especially in some specific occasions that require large-scale and large-scale data collection, such as the measurement of high-sp...

Problems solved by technology

However, in practical engineering applications, the increase in the amount of data at the monitoring site will often lead to an increase in the cost of measurement

Especially in some specific occasions that require large-scale and large-scale data collection, such as the measurement of high-speed rail track settlement and offset, if the existing measurement methods are used, the measurement cost will be greatly increased

[0003] In addition, there are still occasions where the displacement measurement of each monitoring point needs to be accurately synchronized. For example, for the deformation of a bridge under load, if the deformation data of each measuring point is not synchronized, the measurement results can only be qualitatively judged by extreme values ​​at most. It is difficult to combine with each other and comprehensively use in stress-strain back analysis, which will lead to a wrong judgment on the actual situation of the bridge
