Abstract
A ground working system includes at least one self-driving ground working device, which has a drive and a control unit. An operating region (A) is bounded by a wire, wherein the ground working device travels along a traveling path (W) determined by the control unit in the operating region (A). A base station has a transmission unit, which is electrically connected to the wire and by which a wire signal is transmitted. The wire signal transmitted on the wire is electrically received by a reception unit of the base station, compared with a predetermined setpoint signal and, in the event of a deviation of the electrically received wire signal from the predetermined setpoint signal, the transmitted wire signal is changed.
