The invention relates to a connecting and charging system comprising an automatic walking device and a charging station. The automatic walking device comprises a circuit receiving module. The circuitreceiving module comprises a battery pack and a single-chip microcomputer 1 connected to the battery pack. The battery pack is connected with positive and negative receiving lines, the positive receiving line is provided with a receiving control switch connected to the single-chip microcomputer 1, and the negative receiving wire is connected to a power detecting switch connected to the single-chipmicrocomputer and the battery pack. The charging station includes a charging module which includes a single-chip microcomputer 2 and positive and negative charging lines connected to the single-chipmicrocomputer 2. After the automatic walking device is connected to the charging station, after the single-chip microcomputer 2 detects that the positive and negative receiving lines are connected tothe positive and negative charging lines, the charging control switch is controlled to be switched on, thus the positive and negative receiving lines are powered on, and when the single-chip microcomputer 1 receives a power-on signal and the power detecting switch is switched off, the control receiving switch is controlled to be switched on to charge the battery pack. According to the system, theconvenience of charging is improved.
