Sweeping robot back charging system and back charging control method thereof

Abstract

The invention discloses a sweeping robot back charging system and a back charging control method thereof. The system comprises a charging seat, six infrared receiving tubes and a back charging control device, wherein the charging seat is used for dividing a region in front of the charging seat into six different signal areas; the six infrared receiving tubes are arranged on the sweeping robot; the back charging control device is used for controlling the six infrared receiving tubes to be opened when the sweeping robot needs charging, the sweeping robot is controlled to walk towards a middle near field area when any infrared receiving tube receives an infrared signal transmitted by the charging seat, and the back charging control device controls the sweeping robot to walk continuously until the sweeping robot and the charging seat to be in successful butt joint when the fifth infrared receiving tube and the sixth infrared receiving tube receive a middle near field infrared signal. The system can control the sweeping robot to quickly return to the charging seat, the charging return time is effectively shortened, and as a front-end or tail-end butt joint mode is adopted, butt joint stability caused when a left edge brush and a right edge brush are adopted to brush the charging seat during the butt joint process can be avoided, and accurate butt joint is realized.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a sweeping robot recharging system and a recharging control method for the sweeping robot recharging system. Background technique [0002] At present, the way for the sweeping robot to return to the charging stand is relatively simple. For example, the direction of the charging stand is judged by the strength of the received left and right infrared signals. Although the sweeping robot can be controlled to return to the charging stand, the return speed is slow, and the probability of accurately docking with the charging stand is relatively low, and it cannot adapt to complex environment. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, an object of the present invention is to propose a sweeping robot recharging system capable of controlling the sweeping robot to...
