Abstract

The invention provides a north orientation reference device for self calibrating. A pair of distributed north orientation foundation seats are arranged on a foundation plane; collimators are mounted on the distributed north orientation foundation seats through a collimator adjusting mechanism; a reference plane mirror adjusting mechanism and a gyro theodolite mounting adjusting seat are arranged between the two distributed north orientation foundation seats. As the north orientation reference device adopts the reference plane mirror adjusting mechanism as a main north orientation reference, and adopts the center of an infinite target cross reticle produced through the two symmetrically distributed collimators as an auxiliary north orientation reference, in combination with the gyro theodolite mounting adjusting seat, the north orientation reference device can not only realize calibration of different models of gyro theodolites, but also realize mutual calibration of the north orientation references through the mutual comparison of the numerical values of the main reference and the auxiliary reference during north orientation measurement, and effectively avoids north orientation reference movement caused by misoperation and possible foundation deformation. The north orientation reference device is suitable for serving as a north orientation reference device for self calibrating.

Description

technical field [0001] The north reference device in the field of measurement proposed by the invention is mainly used in the north calibration of the north orientation device of the gyro theodolite. Specifically, a self-verifying northbound reference device. Background technique [0002] The gyro theodolite is an instrument that uses the principle of inertia to find north independently. Gyro theodolite is a precision instrument composed of gyroscope and theodolite. It has the functions of orientation and angle measurement. According to the principle of gyroscope, it can automatically find and track the geographic north according to the north component of the earth's rotation angular velocity, and can accurately measure The azimuth of the ground point. Compared with the traditional north-facing instruments gyrocompass and magnetic compass, it has the advantages of all-weather, strong maneuverability, high precision of autonomous orientation, fast orientation speed, simple ...
