Total station instrument combined location method based on optical fiber gyro

Abstract

This invention relates to a kind of fiber-optic gyro based, full station instrument combination orientation mode, and applies to plotting work. In plotting scene, the invention connects fiber-optic gyro(1) with full station instrument telescope(3) by adaptor(2), and make optical fibre gyro can follow full station instrument telescope simultaneously do 180 degree turning reel full station instrument cross shaft, respectively on two horizontal positions of east and west direction of gyro axis that differ by 180 degree; each horizontal position process 2 x 2 position gyro data acquisition on full station instrument perpendicular tray that differ by 180 degree; using formula to count out full station instrument collimation axis true azimuth, survey station meridian convergence angle, then can obtain full station instrument collimation axis grid azimuth, realize full station instrument orient. The invention structure is simple, not need to process alignment error calibration, just simple operation can realize full station instrument orient on only one control point situation. The invention can be used for town, forest, and mountainous area such on distressed area's plotting work.

AI Technical Summary

Benefits of technology

The technical effect of this patented technology for an Optical Fiber Gyroscopic Total Station (FTG) combining orientational methods involves simplifying its construction without requiring any special equipment or tools at both ends. It allows users to install these devices while still being able to accurately determine their position with respect to another object called thetotal station. Additionally, the new design uses smaller and lighter components than traditional mechanisms like electromechanics, which makes them more reliable but less resistant against external shocks compared to older designs such as electrostatic MEMS). Overall, this innovation improves overall performance and efficiency in measuring angles.

Problems solved by technology

This technical problem addressed in this patents relates to improving the efficiency and accuracy of automatically oriented systems (ATS) without requiring cumbersome manual adjustment processes such as alignment and calibration devices. Current methods require bulky hardware components like goniometers and guiding lines attached to the machine frame, making them hard to install accurately due to their size and complexity.
