Title:
HIGH-PRECISION GRAB BUCKET GRABBING POSITION CONTROL METHOD HAVING RADAR FEEDBACK
Document Type and Number:
WIPO Patent Application WO/2023/040079
Kind Code:
A1
Abstract:
A high-precision grab bucket grabbing position control method having radar feedback. The method comprises the following steps: constructing a two-dimensional planar model of a working area according to a working position of a grab bucket, and locating each working point of the grab bucket; constructing a three-dimensional stereoscopic model according to the lengths, widths and heights of different fermentation pits, and detecting the states of material stacks in the different fermentation pits; by combining the heights of the material stacks in the different fermentation pits, and the running distance, running acceleration and running speed of the grab bucket, calculating the optimal grabbing route of the grab bucket, and completing a grabbing action; and updating the three-dimensional stereoscopic model, repeating the process of calculating the optimal grabbing route, and cyclically executing the grabbing action. By means of the control method, the optimal grabbing route of a grab bucket is calculated by comprehensively taking the heights of material stacks, the distances from the material stacks to a feeding point, the running acceleration of the grab bucket and the running speed of the grab bucket into consideration, so as to control a grabbing position, such that the grabbing efficiency is high.
