Electronic total station apparatus with triaxial compensation function

Abstract

The invention discloses an electronic total station apparatus with a triaxial compensation function. The electronic total station apparatus comprises a machine body, a lower laser centering device, a distance measuring head, a weakener and a triaxial compensator, wherein the lower laser centering device is arranged at the left side of the machine body; the distance measuring head is arranged in the middle of the machine body; the weakener is arranged inside the machine body and has a position recognition function; the triaxial compensator is arranged inside the machine body; the distance measuring head is connected with the machine body through a connecting shaft and a transverse sleeve shaft; a vertical code wheel is fixed at the end surface of the transverse sleeve shaft; a group of photoelectric converters is arranged at each of the two sides of the vertical code wheel. The electronic total station apparatus has the advantages that an absolute code wheel angle measuring system with simple structure is used; data can be read without zero crossing; the regulation and alignment operation is simple; through the arrangement of the weakener with a position recognition function, the total station apparatus can effectively avoid the problem of reflection callback signal desynchrony caused by laser diffraction; through repeated refraction of a condensing lens, a reflector and a beam splitting prism, the inclination angle of reflection liquid is transmitted to a main base plate to be corrected, so that the measurement angle is more precise.

Description

technical field [0001] The invention relates to the field of engineering measuring tools, in particular to an electronic total station with a three-axis compensation function. Background technique [0002] Electronic total station is a measuring instrument that can measure angle (horizontal angle, vertical angle) and distance (slant distance, horizontal distance, height difference) at the same time. It is composed of mechanical, optical and electronic components. It only needs to be installed once. , the instrument can complete all the measurement work on the station, so it is called "total station". It is widely used in the measurement work of control measurement, detail measurement, construction lofting and deformation observation. [0003] In the electronic total station, the function of the light reduction plate is to adjust the intensity of the passing laser according to the measurement needs, so that it meets the light intensity detection range of the detection circui...

Problems solved by technology

[0005] Most of the existing electronic total stations use photoelectric incremental angle measurement system. The mechanical structure of this system is relatively complicated, and it can only be used after turning on the machine. Difficult to operate

[0006] At present, the electronic total station with two-axis compensation is the most used, which can only compensate for one plane, but cannot achieve three-axis compensation, so that there is still a large error in the measured angle, or it can be adjusted manually, which wastes manpower and time. , low work efficiency

[0007] To sum up, how to design a three-axis compensation electronic total station with a simple structure of the angle measurement system and can effectively avoid the problem of asynchronous reflection and callback signals caused by laser diffraction has become one of the problems urgently needed to be solved by those skilled in the art
