High-anti-interference fan-shaped laser wireless settlement gauge and monitoring method thereof

Abstract

The invention discloses a high-anti-interference fan-shaped laser wireless settlement gauge and a monitoring method thereof. The high-anti-interference fan-shaped laser wireless settlement gauge comprises a case, a CIS photosensitive image sensor, a processor, a laser emitter, a suspension frame, a wireless signal transceiver and a power supply battery, wherein the CIS photosensitive image sensor, the processor, the laser emitter, the suspension frame, the wireless signal transceiver and the power supply battery are arranged inside the case; the CIS photosensitive image sensor and the laser emitter are arranged at the two opposite sides of the case; a light sensing plate assembly of the CIS photosensitive image sensor consists of a light sensing plate, an attenuation film, an optical filter and a polarizing film in sequential arrangement from inside to outside; the light sensing plate is provided with a light guide hole; the CIS photosensitive image sensor is in communication connection with the processor; the processor is in communication connection with the wireless signal transceiver. The high-anti-interference fan-shaped laser wireless settlement gauge provided by the invention has the advantages that the principle of a constructible system is simple; the deployment is facilitated; connected pipelines and cables do not exist; the construction is convenient; the comprehensive cost is low; the continuous work can be realized; high measurement stability and precision are realized; the convenient cascade connection can be realized; the high-anti-interference fan-shaped laser wireless settlement gauge is particularly suitable for monitoring the roadbed, bridge and tunnel surface settlement.

Description

technical field [0001] The invention belongs to the technical field of civil engineering safety monitoring, and in particular relates to a high anti-disturbance fan-shaped laser wireless settlement instrument and a monitoring method thereof. Background technique [0002] With the rapid development of social economy, the precision requirements for the stability monitoring and control of high-speed railways, tunnels, bridges, dams, and foundation pits are getting higher and higher. In recent years, research papers and patents on laser sedimentation instruments It is published from time to time, but the mature products are still blank. At present, most of the settlement monitoring adopts traditional physical methods or electronic equipment-assisted measurement methods, which mainly have the following shortcomings: [0003] 1. For surface settlement monitoring, monitoring piles, settlement plates, steel rule settlement meters, settlement tubes, etc. are mostly used, and the obse...

AI Technical Summary

Problems solved by technology

[0003] 1. Surface settlement monitoring, mostly using monitoring piles, settlement plates, steel rule settlement instruments, settlement tubes, etc., the observation accuracy is low, and it is difficult to meet the settlement observation requirements of the project

[0004] 2. The subgrade internal settlement monitoring mostly uses hydraulic profile settlement instruments, vibrating wire profile settlement instruments, horizontal inclinometers, etc. This type of observation is complicated to install and use, and the cost is high. It does not meet the actual needs of the project and is not conducive to large-scale promotion.
