An automatic calibration method for a grader

Abstract

The invention relates to the technical field of land leveling, in particular to an automatic calibration method for a grader. It consists of: measuring the height of the first antenna from its direct surface to the ground and recording it as x n , Measure the height of the first antenna facing the ground from the horizontal point and record it as a n , measure the height from the second antenna to the ground and record it as y n , Measure the height of the second antenna facing the ground from the horizontal point and record it as b n , the height difference between the first antenna and the second antenna is set to h n , then the calculation formula is h n =Σ[(x n +a n )‑(y n +b n )] / n. In this embodiment, the height difference between the first antenna and the second antenna at multiple locations of the dual-antenna motor grader is measured, and a more accurate height difference is obtained by taking an average value. At the same time, by measuring the height of the ground facing the first antenna and the second antenna, the problem of inaccurate height adjustment of the first antenna and the second antenna caused by uneven ground can be reduced.

Description

technical field [0001] The invention relates to the technical field of land leveling, in particular to an automatic calibration method for a grader. Background technique [0002] With the development of the times, agriculture has also begun to enter the era of automation. For example, satellite levelers have been used to replace manual land leveling. However, satellite levelers need to be manually measured for the height difference between the two antennas during installation and calibration. Personnel must have high professional skills, and manual measurement is prone to errors. Contents of the invention [0003] The purpose of the present invention is to provide an automatic calibration method for a motor grader, which has the advantage of accurate calibration, aiming at the defects and deficiencies of the prior art. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] An automatic calibration method for a mo...
