Regression guiding method and system based on positioning system

The invention relates to a regression guiding method based on a positioning system. The method is used for guiding an automatic walking device to a charging station, and comprises the following steps: enabling the automatic walking device to be regressed to a predetermined position of the charging station by use of a positioning technology; and connecting the automatic walking device to the charging station by use of a butt joint apparatus. The regression guiding method based on the positioning system involves, first of all, enabling the automatic walking device to be rapidly regressed to somewhere nearby the charging station by use of the positioning technology and then connecting the automatic walking device to the charging station by use of the butt joint apparatus, such that the time for the automatic walking device to be regressed to the charging station is generally shortened. The invention also simultaneously provides a regression guiding system based on a positioning system. The system can control the automatic walking device to be rapidly regressed to somewhere nearby the charging station at a linear path through a positioning module and then connects the automatic walking device to the charging station through the butt joint apparatus, such that the efficiency of regressing the automatic walking device to the charging station is effectively improved.
