A Total Station Monitoring Displacement Method Based on Vibration Correction

Abstract

The invention discloses a vibration correction total station displacement monitoring method. The method includes constructing a forced centering observation platform in an area to be monitored, fixingone or a plurality of vibration monitors on a base of the observation platform to correct the position of a target point and using a corrected value as final coordinates of the target point. According to the method, the accuracy degradation caused by vibration can be effectively eliminated.

Description

technical field [0001] The invention belongs to the technical field of construction monitoring, and in particular relates to a vibration-corrected total station monitoring displacement method. Background technique [0002] In recent years, my country's urban infrastructure construction has developed rapidly. During the construction process of the project, it is necessary to monitor the displacement of the project itself and the surrounding environment to determine the safety of the project itself or the surrounding environment; however, the surrounding environment of the construction site is complex. The instrument is often affected by vibration during the monitoring process, resulting in a decrease in measurement accuracy and failing to meet the monitoring requirements. How to effectively solve the impact of vibration on the monitoring displacement of the total station has become a crucial issue. [0003] At present, there are mainly two methods to solve the impact of vibrat...

Problems solved by technology

The first method is to build the total station observation platform outside the vibration-affected area, which will increase the monitoring distance and reduce the monitoring accuracy, which cannot meet the actual needs of the site, and there may be other seismic sources outside the affected area, which will cause secondary impact on the total station.

The second method is to build the total station observation platform in the affected area. During the monitoring process of the total station, stop the construction steps affected by the vibration as much as possible, but it will affect the construction progress of the project.

[0004] The above two methods cannot eliminate the impact of vibration on the monitoring level of the total station while ensuring the displacement accuracy of the total station and ensure the construction progress
