Abstract

The invention relates to a horizontal one-observation set accuracy testing system of a theodolite at extreme temperature. The testing system comprises a data acquisition and control computer, an autocollimator, a constant-temperature test box, a multi-tooth division table and a planar mirror which is fixedly connected with a theodolite to be tested; the multi-tooth division table is arranged inside the constant-temperature test box and is electrically connected with the data acquisition and control computer through a cable; an optical window is arranged on the side wall of the constant-temperature test box; the theodolite to be tested is arranged on the multi-tooth division table; the autocollimator is opposite to the planar mirror, the optical window is arranged between the autocollimator and the planar mirror, and the autocollimator and the planar mirror are arranged at the same height position; and the data acquisition and control computer is respectively connected with the multi-tooth division table and the autocollimator. The invention provides a horizontal one-observation set accuracy testing system of the theodolite, which is high in automation degree, measurement accuracy and stability at the extreme temperature.

Description

technical field [0001] The invention belongs to the field of optics, and relates to a precision testing device, in particular to a theodolite level-measurement precision testing system under extreme temperature conditions. Background technique [0002] Theodolite is a precision photoelectric angle measuring instrument for geodesy that measures the azimuth angle of the horizontal plane and the elevation angle of the vertical plane. With the development of optoelectronics, digitization and automation, the modern theodolite is not only a geodesic instrument, but is now widely used in surveying and mapping, meteorology, railways, highways, bridges, tunnels, water conservancy, mines, automobiles, ships, urban construction and other astronomical surveys , Geodetic Surveying, Precision Engineering Surveying and Metrology. Of course, with the development of industry and national defense construction, theodolite is also widely used in aerospace, shooting range measurement, missile t...
