Gyrotheodolite integrated with north and south seeking function and implementing method thereof

Abstract

The invention discloses a gyrotheodolite integrating north-finding and south-finding function and a method of realizing the same. The gyrotheodolite comprises a gyro power and a gyro motor; the gyro power supplies three phase alternating voltage or a one path direct voltage to the gyro motor; the gyrotheodolite is characterized that: the gyrotheodolite further comprises a controlling unit for controlling the phase sequence change of the three phase alternating voltage or controlling the polarity change of the one path direct voltage. The method comprises changing the phase sequence or polarity of the supplying power of the gyro motor in the gyrotheodolite to realize the positive rotation and reversing switch of the gyro motor, thereby realizing the switch of the north-finding and south-finding function of the gyrotheodolite. When the gyrotheodolite produced or remodeled by the invention is located, the gyrotheodolite is not affected by measuring controlling point set and the surrounding environment, that is to say it is measured at each environment, which solves the long-standing problem of affecting the measuring work in orientation of the gyrotheodolite.

Description

technical field

[0001] The invention belongs to the technical field of electronics and instruments, and relates to a gyro theodolite with integrated north-seeking and south-seeking functions and a realization method thereof. Background technique

[0002] When carrying out the gyro theodolite orientation operation, it is first to find the north, and after finding the north direction, the azimuth angle of either side can be determined. In the field of directional measurement, if a gyro theodolite is used to find north, according to the transit method, time difference method and multi-point time measurement method, the operator usually stands in the south of the gyro theodolite so that the theodolite telescope can be illuminated. Accurate to the approximate north direction, that is, set the zero position of the gyro reticle in the approximate north direction, and observe the movement of the gyro cursor in the objective lens of the gyroscope, so as to lock, start the gyro, lower...
