Control method, autonomous operation device, docking station, and autonomous operation system

A control method, applied to an autonomous operation device, the method comprising:

• transmitting a first signal to a docking station based on a first preset period when the autonomous operation device is in a first state, to enable the docking station to control, if the first signal is received, power terminals of the docking station for charging the autonomous operation device to be de-energized;
• stopping transmitting the first signal to the docking station when the autonomous operation device is in a second state, to enable the docking station to control, if the first signal is not received within preset duration, the power terminals to be energized, wherein the preset duration is greater than a period length of the first preset period;
• and
• charging a battery in the autonomous operation device after the autonomous operation device in the second state is docked with the power terminals of the docking station.
