Abstract
A autonomous moving device, moving and working in a working region limited by a boundary wire, and including at least one boundary sensor, detecting boundary signal and outputting boundary signal output; a control module, electrically connected to the boundary sensor, and judging type of the boundary signal output, wherein the control module comprises an estimation unit, estimating whether the type of the boundary signal output in a predetermined estimation period is consistent or not, and if consistent, the control module judges that the boundary signal output is stable; the control module judges position relation of the boundary sensor relative to the boundary wire based on the type of the stable boundary signal output.
