Embodiment Construction

[0023] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0024] Landslides, debris flows and other geological disasters are very likely to occur on large-scale engineering sites, and the damage caused by geological disasters to the project is very huge. significance. The most commonly used geological displacement monitoring method is the Beidou monitoring technology, but the deployment and position change ...

Abstract

This application proposes an engineering displacement monitoring method and equipment. The method includes: a laser emitting device receives a preset command, and emits a cross-striped laser beam with a first preset pulse waveform; a laser sensing target receives the cross-striped laser beam beam, read the coordinate values ​​of several points on the cross strip, determine the position information of the intersection point of the cross strip according to the coordinate value, and send it to the laser emitting device, so that the laser emitting device will The location information is sent to the remote platform to monitor geological displacement through the remote platform. The displacement monitoring method proposed in this application can improve the accuracy of large-distance displacement monitoring in engineering by emitting cross laser beams and matching the point calculation of induction targets.

Description

technical field [0001] The present application relates to the technical field of displacement monitoring, in particular to an engineering displacement monitoring method and equipment. Background technique [0002] The terrain of the project site is complex and diverse, and geological disasters such as landslides, collapses, and debris flows are prone to occur in many areas. Therefore, micro-displacement monitoring of geological landslides is required to monitor the geological conditions in real time, predict the possibility of geological landslides in advance, and prevent them in advance. [0003] Beidou monitoring technology is a common technical means for geological displacement monitoring, but the cost of Beidou monitoring technology is relatively high, the project deployment and change are more complicated, and the support of reference stations is required. The use of photoelectric displacement monitoring technology can reduce costs, and the project deployment and change...
