Total station simulator based on IMU gyroscope

Abstract

The invention discloses a total station simulator based on an IMU gyroscope, and relates to the technical field of measuring instruments. Comprising a right frame, a left frame and a frame connecting seat, an encoder mounting seat is fixedly arranged at the bottom of the right frame; the right frame is provided with an absolute value encoder through an encoder mounting seat; a miniature vertical conductive slip ring is arranged on the left frame through a conductive slip ring mounting seat II; a bottom frame seat is arranged at one end part of the frame connecting seat through a bearing II; the bottom frame seat is provided with a micro horizontal conductive slip ring through a micro horizontal conductive slip ring mounting seat; according to the invention, the high-precision three-axis IMU gyroscope is used for detecting the horizontal attitude of the total station simulator, so that the detection precision of the horizontal attitude is improved; a high-integration miniaturized conductive slip ring is adopted, so that a power supply and signal transmission of a rotating mechanism of the device are integrated, the stability and reliability of the total station simulator are improved, and the total station simulator is convenient to carry, reliable in operation, suitable for being used in various environments and capable of meeting the training and learning use requirements of technicians.

Description

technical field [0001] The invention belongs to the technical field of measuring instruments, in particular to a total station simulator based on an IMU gyroscope. Background technique [0002] The total station, that is, the total station electronic rangefinder, is a high-tech measuring instrument integrating light, machinery and electricity. All-in-one surveying and mapping instrument system. Compared with the optical theodolite, the electronic theodolite replaces the optical dial with a photoelectric scanning dial, and replaces the manual optical micrometer reading with the automatic recording and display reading, which simplifies the angle measurement operation and avoids the occurrence of reading errors. Because it can complete all the survey work on the station once the instrument is placed, it is called a total station. It is widely used in the field of precision engineering measurement or deformation monitoring such as large-scale buildings on the ground and underg...

Problems solved by technology

[0004] The purpose of the present invention is to provide a total station simulator based on an IMU gyroscope. By using a high-precision three-axis IMU gyroscope to measure the horizontal azimuth and attitude of the device, an absolute encoder measures the vertical azimuth, and transmits the data to the self-developed control board. processing, and then transmit the position information processed by the control board to the micro-display control board through the miniature conductive slip ring, and can directly observe the virtual scene inside the total station device through the magnifying eyepiece, which solves the difficulty in the operation and use of the existing total station, which is not convenient Take control of usage issues
