Description

technical field [0001] The invention relates to the technical field of intelligent information measurement, in particular to a laser measuring device and method for measuring three-way displacement of a pipeline with high precision, high reliability and strong environmental adaptability. Background technique [0002] Pipeline three-dimensional displacement is an important parameter for pipeline stress analysis, an important means for pipeline design verification, and an important basis for pipeline transformation. Whether the actual displacement of the pipeline is correct or not is directly related to the safety and service life of the pipeline. [0003] At present, the three-way displacement of the pipeline mainly adopts the mechanical relative displacement measurement method, that is, a steel needle that can only move vertically is fixed in the direction perpendicular to the pipeline axis, and an aluminum plate with a coordinate system is placed under the needle tip. The s...

Problems solved by technology

This method is simple in equipment and easy to operate; the disadvantage is that the reading error is large, the reliability is not high, and it cannot be monitored automatically and in real time.

Moreover, it is greatly affected by the spatial position of the pipeline, so it can only measure pipelines that are close to the ground or wall
