Problems solved by technology

[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

Embodiment Construction

[0018] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment as required after reading this specification, but as long as they are within the rights of the present invention All claims are protected by patent law.

[0019] The present invention relates to an automatic calibration method for a grader, which includes: step 1: select a dual-antenna grader (as a preference, select a dual-antenna satellite grader), and the dual-antenna grader includes: a grader, a first antenna, a second An antenna and a control system, wherein both the first antenna and the second antenna are controlled by the control system. Step 2: Take a certain point on the ground as the horizontal point, place the motor grader anywhere on the ground, use the control system to control the satellite to measure the height of the first antenna from its direct face to the grou...

Abstract

The invention relates to the technical field of land leveling and particularly relates to an automatic calibration method of a land leveler. The method comprises steps of measuring a height from a first antenna to the ground and recording the height as xn, measuring a height from the ground just opposite to the first antenna to a horizontal point and recording the height as an, measuring a heightfrom a second antenna to the ground and recording the height as yn, and measuring the height from the ground just opposite to the second antenna to the horizontal point and recording the height as bn,setting height difference between the first antenna and the second antenna to be hn, and a calculation formula being hn=sigma[(xn+an)-(yn+bn)] / n. The method is advantaged in that the height difference between the first antenna and the second antenna of the double-antenna land leveler at a plurality of places is measured, and the more accurate height difference is obtained in a mode of averaging,moreover, the heights of the ground opposite to the first antenna and the second antenna are measured, so a 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...
