Description

A Total Station for Automatic Alignment and Measurement

technical field

Background technique

In the field of construction, construction measurement is used in the entire construction process, from site leveling, building positioning, foundation construction, to building component installation, etc., construction measurement is required. In construction surveying, often due to the short side length of the survey, a large amount of survey work is to place instruments at various points on the baseline or axis of each building to perform survey work. It can be seen that the rapid and accurate centering of the instrument occupies a crucial position in the construction survey work, which directly affects the accuracy and efficiency of the survey work.

With the development of science and technology, in order to improve the centering accuracy, the instrument adopts optical centering. Although the optical centering has high precision in the measurement work, the leveling and centering must be carried out alternately. Because the measuring point may deviate from the marking center of the optical plummet after leveling, it needs to be re-centered, so these two steps must be repeated until both goals are achieved. At present, it is generally used to fix one leg, rotate the other legs to center the instrument, and then use the telescopic legs to center the circular level bubble. In this way, it is difficult to achieve both centering and leveling during the operation. Therefore, some surveyors spend a lot of time on optical centering and leveling operations, which affects work efficiency and also affects the centering accuracy. For this reason, centering is a must for surveyors, especially construction surveyors, in their work. question.
