基于北斗伪卫星系统的建筑形变监测

Building Deformation Monitoring Based on Beidou Pseudo-Satellite System

本文设计了一种基于北斗伪卫星系统的微变形监测方法,能够以较高精度对建筑物的微变形进行监测。因为监测点的三维位置变化能够反映出监测点处发生的形变,因此在搭建好北斗伪卫星系统之后,将接收机放置在监测点处,通过接收机定位结果的变化来判断监测点处是否发生了形变。为了验证设计的北斗伪卫星系统的有效性,我们进行了一组实验来进行评估。实验结果表明:与传统的GNSS系统监测相比,本文设计的北斗伪卫星系统具有更高的监测精度以及更好的稳定性,三维监测精度分别为0.0011m,0.0007m以及0.0024m,同时,与传统的利用全站仪以及激光测量方法相比,北斗伪卫星系统能够实时的打印出监测结果,从而更容易对建筑物形变进行判断,防止危险的发生。

In this paper,a micro-deformation monitoring method based on Beidou pseudo-satellite system is designed,which can monitor the micro-deformation of buildings with high precision.Because the three-dimensional position change of the monitoring point can reflect the deformation occurring at the monitoring point,after the Beidou pseudo-satellite system is set up,the receiver is placed at the monitoring point,and the deformation of the monitoring point is judged by the change of the positioning result of the receiver.In order to verify the effectiveness of the designed Beidou pseudo-satellite system,we conducted a set of experiments to evaluate it.The experimental results show that the Beidou pseudo-satellite system designed in this paper has higher monitoring accuracy and better stability than the traditional GNSS system monitoring,and the three-dimensional monitoring accuracy is 0.0011m,0.0007m and 0.0024mrespectively.At the same time,compared with the traditional use of the total station instrument and laser measurement method,Beidou pseudo-satellite system can print out the monitoring results in real time,so it is easier to judge the deformation of the building to prevent the occurrence of danger.
