Problems solved by technology

[0004] Due to the structural limitation of the existing gyro theodolite, it is difficult to guarantee the quality and accuracy of data acquisition in the north-seeking process of the teaching system, so the teaching demonstration process is difficult to realize. Two types of devices with different structures, but currently these two devices are independent products, so it is necessary to purchase two devices at the same time, which increases the economic cost, placement space and time for connection and assembly, and brings inconvenience to the demonstration process

Abstract

The invention relates to a gyro theodolite teaching system which comprises a gyro theodolite, a high-definition camera, a direct current voltage stabilizing power supply, a computer, a large-screen television and a controller. The controller is connected with the direct current voltage stabilizing power supply, the computer and the gyro theodolite. The gyro theodolite, the high-definition camera and the large-screen television are connected with the computer. According to the invention, the gap in domestic gyro theodolite teaching is filled; teaching and use of the gyro theodolite can be completed in a virtual environment; a trainee can quickly grasp the principle of inertial north seeking, the use method and the like of the gyro theodolite; in addition, a theodolite clamping device is designed; the operation of the north seeking algorithm of a theodolite headblock or a gyro headblock is realized by using a gyro theodolite.

Description

technical field [0001] The invention relates to the field of teaching aids, in particular to a teaching system for a gyro theodolite. Background technique [0002] The gyro theodolite is a device used to establish a north reference, which uses the characteristics of the gyro to achieve the purpose of finding north. Its orientation principle is that the sensitive part of the gyro, which is suspended by a hanging wire and whose center of gravity moves down, is sensitive to the horizontal component of the earth's rotation angular velocity. Under the action of gravity, a moment of northward precession is generated, so that the main axis of the sensitive part of the gyro (that is, the H vector) revolves around The meridian plane swings back and forth, and the optical signal of the sensitive part of the gyroscope is converted into an electrical signal by the photoelectric sensor and sent to the controller. The angle displayed by the controller is the angle between the zero positi...
