Abstract

The invention discloses an electronic total station for opening a lens. The electronic total station comprises a base, a machine body, a ranging system, an angle measuring system, a display screen and a power supply system, wherein the ranging system is arranged on the machine body and is provided with a telescopic, and an objective lens of the telescopic is provided with a through hole, the telescopic is arranged on a ranging head, and the ranging head belongs to a part of the ranging system. According to the electronic total station for opening the lens, disclosed by the invention, the through hole is formed in the lens, electromagnetic waves for ranging directly pass through the through hole when being emitted through the objective lens so as to avoid the inexact ranging due to reflection of the surface of the objective lens on the electromagnetic waves, and thus the measurement is relatively exact.

Description

technical field [0001] The invention relates to a total station, which is mainly used in the fields of geodetic surveying, industrial surveying and the like. Background technique [0002] Total station is a high-tech measuring instrument integrating light, mechanics and electricity. It is a surveying and mapping instrument system integrating horizontal angle, vertical angle, distance (slope distance, horizontal distance) and height difference measurement functions. It is used in precision engineering measurement or deformation monitoring fields such as large-scale buildings on the ground and underground tunnel construction. The ranging head is an important component of the total station. It is used to measure the distance between the center of the total station and the distant target. In addition, there is a telescope on the ranging head to aim at the target. Its working principle is as attached figure 1 As shown, the emission group 11 emits laser light, and the emitted di...
