A Method of Using Total Station to Measure Angle and Monitor Plane Displacement

Abstract

The invention discloses a method of measuring displacement of an angle monitor plane by using an electronic total station. The method comprises following steps of: setting at least one monitoring point on a monitored target; establishing two forced alignment observation piers in a stable area nearby the monitored target, establishing a coordinate system, making an observation pier A and an observation pier B in the same coordinate system, and measuring coordinates of the observation pier A and the observation pier B; observing backsight points corresponding to the observation pier A and the observation pier B on the observation pier A and the observation pier B by using the electronic total station, and obtaining a horizontal angle alpha and a horizontal angle beta corresponding to the monitoring point separately in a generated coordinate system; and establishing a simultaneous equation according to positions of the horizontal angle and the observation piers, so as to obtain coordinates of the monitoring point. The method of measuring displacement of the angle monitor plane by using the electronic total station can prevent impact of terrain and weather on angle measurement accuracy, and improves monitoring accuracy effectively.

Description

technical field [0001] The invention belongs to the technical field of engineering monitoring, and in particular relates to a method for using a total station to measure angles and monitor plane displacements. Background technique [0002] In the process of civil engineering construction, it is often necessary to monitor the surrounding sensitive buildings or the project itself. At present, the monitoring plane displacement mainly uses the total station to measure the plane coordinates, but the measurement distance of the total station is greatly affected by the sight distance and climate , resulting in monitoring accuracy that cannot meet the needs of on-site production and specification requirements. [0003] At present, in order to improve the accuracy of total station monitoring of building plane displacement, the observation position is mainly used to be close to the target point, thereby shortening the observation distance; or monitoring is carried out when the weather...

Problems solved by technology

However, as my country's urbanization process is accelerating, many civil engineering surroundings cannot be observed at close range, or observations cannot be made after the weather conditions are stable. Therefore, it is necessary to improve the original monitoring method using total stations so that it can avoid distance and the effect of climate on angle measurement accuracy
