Problems solved by technology

In practical applications, due to the influence of housing buildings, high walls, big trees and other obstructions, the shadow area with weak satellite positioning signal is caused, and the positioning accuracy of the automatic mowing robot is affected in this shadow area, so that the automatic mowing robot mows Grass gradually deviates from the planned mowing path. When walking out of the shadow area, there may be a sudden change in position, which affects the continuity of mowing, and even cannot achieve full-coverage cutting, which ultimately affects the quality of mowing.

Abstract

The invention relates to a hay mower navigation method and device and a hay mower. The method comprises the steps of receiving satellite positioning signals of position points on a driving path; according to the satellite positioning signals, judging whether the position points are signal quality turning points or not, if the position points are the signal quality turning points, comparing the distance between the position points and each planned path, and taking the planned path with the minimum distance as a target driving path, wherein the planned path is composed of a plurality of ordered position points. The method has the advantages of high mowing efficiency and high continuity, the boundary of shadow areas can be effectively determined by setting the quality signal turning points, effective data is provided for determination of the boundary of non-mowing areas, and the minimum repeated path under the maximum coverage rate is ensured.

Description

technical field [0001] The present disclosure relates to the technical field of automation control, in particular to a lawnmower navigation method, device and lawnmower. Background technique [0002] With the development of science and technology, automatic mowing robots can mow grass autonomously according to the planned path without human participation, which provides great convenience for people's production and life. In practical applications, due to the influence of housing buildings, high walls, big trees and other obstructions, the shadow area with weak satellite positioning signal is caused, and the positioning accuracy of the automatic mowing robot is affected in this shadow area, so that the automatic mowing robot mows Grass gradually deviates from the planned mowing path. When walking out of the shadow area, there may be a sudden change in position, which affects the continuity of mowing, and even cannot achieve full-coverage cutting, which ultimately affects the ...
