Going back and charging system for sweeping robot and method for controlling the same
First Claim
1. A going back and charging system for a sweeping robot, comprising:
- a charging station, configured to emit a plurality of differently encoded groups of infrared signals, so as to divide an area in front of the charging station into six different signal regions, wherein the six different signal regions comprise;
a left near field region, a middle near field region, a right near field region, a left far field region, a middle far field region and a right far field region;
six infrared receiving tubes, disposed on the sweeping robot, wherein a first infrared receiving tube, a second infrared receiving tube, a third infrared receiving tube and a fourth infrared receiving tube are respectively disposed at four corners of the sweeping robot in a symmetrical manner with respect to a front-rear direction and a left-right direction, a fifth infrared receiving tube and a sixth infrared receiving tube are disposed at a front end or a rear end of the sweeping robot, and the fifth infrared receiving tube and the sixth infrared receiving tube are symmetrical with respect to the front-rear direction; and
a going back and charging control device, configured to;
control the six infrared receiving tubes to be turned on if it is determined that the sweeping robot needs to be charged;
control the sweeping robot to walk toward the middle near field region if any one of the six infrared receiving tubes receives an infrared signal emitted from the charging station; and
control the sweeping robot to continue to walk until the sweeping robot docks with the charging station successfully if the fifth infrared receiving tube and the sixth infrared receiving tube receive an infrared signal of the middle near field region.
