Floor sweeper, control method and control device thereof

Abstract

The invention discloses a floor sweeper, a control method and a control device thereof. The control method comprises the following steps: taking an initial position of the floor sweeper as a center, dividing an area to be swept within a set range into a plurality of sub-areas; if the previous sub-region exists, deleting the historical grid map created for the previous sub-region , and creating thecurrent grid map for the current sub-region; according to the current grid map, controlling the sweeper to sweep the sub-area from the initial position until the sub-area is swept. The method dividesthe area to be cleaned into a plurality of sub-areas, each sweep builds the current raster map based on only one subregion, and controls the floor sweeper to sweep the sub-regions in turn based on the current grid map, until the cleaning is completed, the occupation of hardware memory and computing resources can be effectively reduced, the operation of the system can be optimized, and the sweeping purpose of the sweeper can be achieved under the limited hardware memory resources and computing resources, so that the sweeper can cover a larger sweeping area.

Description

technical field [0001] The present invention relates to the technical field of household appliances, in particular to a control method of a sweeper, a control device of a sweeper, a sweeper, an electronic device and a non-transitory computer-readable storage medium. Background technique [0002] With the increasing popularity of home service robots, people have higher and higher functional requirements for them. As the most common type of home service robots on the market, sweepers use their intelligence to free users' hands and complete tasks. Efficient cleaning has attracted more and more people's attention. [0003] Among them, the navigation scheme of the sweeper is an important part of intelligence. At present, the navigation scheme of the sweeper is generally: the sweeper first presets the global grid map based on the area to be cleaned, such as a map of N×N size, and then detects obstacles through social equipment such as gyroscopes, collision sensors, and infrared s...

AI Technical Summary

Problems solved by technology

Since the navigation solutions of most sweeping machines are built on the embedded hardware platform, and the memory resources of the embedded hardware are limited, the size of the fixed-size grid map is limited, which cannot meet the large area of ​​the user's house, making the navigation The program has certain limitations
