Self-positioning method and system for intelligent mowing machine

Abstract

The invention discloses a self-positioning method and system for an intelligent mowing machine. After an UWB positioning module wakes up different UWB labels, positioning signals are sent to the UWB labels and timing is started. The UWB labels send positioning feedback signals to the UWB positioning module. After the UWB positioning module receives the positioning feedback signals, timing is stopped. According to the timing result, the distances between the UWB positioning module and the UWB labels are calculated and the intelligent mowing machine is positioned. Through the UWB positioning module arranged on the intelligent mowing machine and the UWB labels arranged at a plurality of predetermined positions, automatic positioning of the intelligent mowing machine is realized and path planning is further made. A shortcoming that an intelligent mowing machine can only work in a limited area randomly in the prior art is overcome and repeated mowing of the prior intelligent mowing machine is avoided. Resources are saved and working efficiency is improved. Besides, no electric fence needs to be put around a glass land, so that cost is saved further.

Description

technical field [0001] The invention relates to the technical field of intelligent lawnmowers, in particular to a self-positioning method for an intelligent lawnmower and a self-positioning system for an intelligent lawnmower. Background technique [0002] The intelligent lawn mower has the function of automatic walking, can prevent the wire from going out within the range of the electronic virtual fence, and can automatically return to charge, and has a certain climbing ability, especially a kind of lawn mowing and maintenance suitable for home courtyards, public green spaces and other places. The intelligent lawn mower can independently complete the work of mowing the lawn without direct human control and operation, and has low power, low noise, exquisite and beautiful appearance, and greatly reduces manual operation. More and more households now have lawnmowers to use for weeding their gardens. [0003] Generally, by placing an electronic fence (ie, an electronic virtual...

Problems solved by technology

This will inevitably lead to the situation where the lawn mower repeatedly moves to mow the grass, which wastes resources and reduces work efficiency.

At the same time, it is necessary to install the cables required for the electronic fence around the grass, which further increases the cost, and the electronic fence is also likely to cause interference to other equipment of the user.
