Problems solved by technology

However, in this solution, when the smart lawn mower needs to be accurately positioned to the charging base station, the positioning accuracy of its ultra-wideband positioning technology is difficult to achieve, and the energy utilization rate of the smart lawn mower is not high. When a positioning tag is blocked , the positioning of the smart mower is prone to inaccurate situations

Embodiment Construction

[0038] The following are specific embodiments of the present invention in conjunction with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0039] Such as Figure 1-4 As shown, a method for positioning an intelligent lawn mower is provided with a first positioning signal receiver 11 and a UWB base station 10 on the intelligent lawn mower 100. The positioning method includes the following steps:

[0040] Receiving a second positioning signal sent by a plurality of UWB positioning tags 300 set in a preset position;

[0041] When the smart lawn mower 100 is moving to cut grass, the smart lawn mower 100 generates a corresponding mowing path according to the second positioning signal and the map data stored in the smart lawn mower 100, and drives along the mowing path ;

[0042] When driving to the charging base station 200 for charging, the smart lawn mower 100 drives to the ch...

Abstract

The invention relates to the technical field of intelligent lawn mowers, and discloses an intelligent lawn mower positioning method and system. A first positioning signal receiving member and a UWB base station are arranged on an intelligent lawn mower. A positioning method comprises the following steps that second positioning signals transmitted by a plurality of UWB positioning labels arranged at preset positions are received; when the intelligent lawn mower advances for mowing lawn, the intelligent lawn mower generates a corresponding lawn mowing route according to the second positioning signals and map data stored in the intelligent lawn mower, and travels along the lawn mowing route; and when the intelligent lawn mower drives to a charging base station for charging, the intelligent lawn mower drives to the charging base station, and when a first positioning signal is received, the intelligent lawn mower aligns and drives to a charging connector of the charging base station for charging. The intelligent lawn mower positioning method and system disclosed by the invention have the advantages that the intelligent lawn mower is high in positioning accuracy, low in error rate and high in energy resource utilization rate, and the whole energy consumption of the intelligent lawn mower positioning system is low.

Description

Technical field [0001] The invention relates to the technical field of intelligent lawn mowers, in particular to a positioning method and system for intelligent lawn mowers. Background technique [0002] With the advent of intelligent and interconnected traditional products, the application of new technologies has increased the demand for traditional lawn mowers, and it has become a trend for intelligent lawn mowers to replace traditional lawn mowers. However, the existing smart lawn mowers generally use magnetic wire smart lawn mowers. This type of intelligent lawn mower has a low level of intelligence. It can only stop when the smart lawn mower touches the boundary line and turn back. Mowing back and forth. As a result, the intelligent lawn mower in the middle area cannot achieve good positioning, and it does not have a good application experience in a site with slippery wheels and unevenness. At the same time, there is a process load for embedding magnetic wires, which requir...
