Description

Technical Field

[0002] Total station is a high-precision measuring instrument, which is widely used in civil engineering, road construction, bridge engineering, mining surveying, urban planning, environmental monitoring and other fields.

[0003] A total station, also known as a total station electronic distance meter, is a high-tech measuring instrument that integrates optics, mechanics and electronics. It is a surveying and mapping instrument system that integrates horizontal angle, vertical angle, distance (slant distance, horizontal distance) and height difference measurement functions. Compared with the optical theodolite, the electronic theodolite replaces the optical degree disk with a photoelectric scanning degree disk, and replaces the manual optical micrometer readings with automatic recording and display of readings, which simplifies the angle measurement operation and avoids the occurrence of reading errors.

[0004] In the prior art, when using a total station, it is necessary to place the total station at a surveying point and adjust the total station to a horizontal position before measuring. When adjusting, the tripod at the bottom of the total station is unfolded and fixedly connected before measuring. The total station has high requirements for the position and height of its surveying point during measurement. In most cases, the three supporting legs on the tripod are composed of multiple connecting rods, and an operator is required to grasp two adjacent connecting rods and stretch them in opposite directions to lengthen or shorten them. However, the height or position of the tripod supporting legs needs to be adjusted multiple times during the adjustment process, and another operator is required to help check at any time whether the current height of the total station meets the measurement requirements. The entire adjustment process is cumbersome and time-consuming. Utility Model Content
