Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] refer to figure 1 , the present invention comprises a self-propelled device 1 and a charging stand 2, can realize the preferred embodiment of the method for guiding the self-propelled device 1 to the charging stand 2 through wireless access, and can be close to the charging stand when the self-propelled device 1 Wired access at 2 o'clock. Preferably, the self-propelled device 1 of this example is a sweeping robot, which can find out the path back to the charging base 2 through wireless access, and can perform wired charging through the charging shrapnel (not shown) of the charging base 2 .

[0023] The charging stand 2 has a first transmitter 21, a central transmitter 20 and a second transmitter 22 arranged at intervals, for sending out a first pilot signal, a central pilot signal and a second pilot signal respectively . Such as figure 2 A...

Abstract

The invention provides a control unit and a method for guiding an automatic walking device to a charging seat. The control unit can be used for enabling the automatic walking device to be guided by a center guidance signal emitted by a charging seat to approach the charging seat. The automatic walking device comprises a shell, a central sensor, the control unit, and two sensors at two sides of the central sensor. The control unit comprises a central judgment unit used for judging the central guidance signal, wherein when the fact that the central guidance signal is sensed by at least one sensor is determined, thus the shell is rotated until the central guidance signal is sensed by central sensor. The control unit also comprises a time correction unit used for time correction, thus the shell is rotated until the central guidance signal is not sensed by central sensor, thus a first time is set, the shell is rotated reversely until the central guidance signal is not sensed by central sensor, a second time is set, and the first time and the second time are utilized to calculate a correction time, wherein the central judgment unit enables the shell to rotate reversely for the correction time, and the shell moves to the charging seat.

Description

technical field [0001] The invention relates to an automatic traveling device, in particular to a control unit for improving the return efficiency and a method for guiding the automatic traveling device to a charging stand. Background technique [0002] In the prior art, the automatic walking device often follows the guidance signal sent by the charging base and gradually returns to the charging base after completing the staged work. For example: after the cleaning work, the sweeping robot will return to the charging stand for charging. [0003] The return method is mainly to refer to a left guidance signal and a right guidance signal sent by the charging base. When the automatic walking device senses one of the guiding signals, it will move to the overlapping area of ​​the two guiding signals, and then gradually return to the charging stand in the overlapping area. However, the automatic walking device only relies on a single sensor for sensing, the sensing angle is limit...
