Autonomous operation device, control method therefor, and autonomous operation system

A control method for an autonomous operation device, wherein the control method is applied to an autonomous operation device, the autonomous operation device is movable within a working region enclosed by a boundary, a docking station is configured on the boundary, a boundary signal generation apparatus configured to feed a boundary signal to the boundary is configured on the docking station, and a signal sensing unit configured to sense the boundary signal is configured in the autonomous operation device, and the method comprises:

• detecting, during a working process of the autonomous operation device within the working region, whether the boundary signal is received through the signal sensing unit, wherein the boundary signal is configured to indicate that the autonomous operation device is located within the working region;
• in a case that the boundary signal is received through the signal sensing unit, controlling the autonomous operation device to continue operation;
• and
• in a case that the boundary signal is not received through the signal sensing unit, controlling the autonomous operation device to stop operation, increasing an amplification gain of the boundary signal by the autonomous operation device, and re-executing the step of detecting whether the boundary signal is received through the signal sensing unit.
