Estimating the term…
A self-propelled device system includes a self-propelled device, a boundary wire configured to define a work area of the self-propelled device and a signal transmitting unit electrically connected with the boundary wire configured to generate and send a boundary signal to the boundary wire that generates a magnetic field when flowing through the boundary wire. The self-propelled device has a signal receiving module and a control module. The signal receiving module uses the magnetic field caused by the boundary signal to generate a boundary wire inductive signal and the control module determines that the boundary wire has a wire break when a relevant parameter of the boundary wire inductive signal is less than or equal to a predefined threshold.
A self-propelled device system, comprising:
A wire break detection method for a boundary wire of a self-propelled device system comprising a self-propelled device, a boundary wire configured to define a work area of the self-propelled device, and a signal transmitting unit, electrically connected with the boundary wire, for generating and sending a boundary signal to the boundary wire wherein the boundary signal generates a magnetic field when flowing through the boundary wire, the wire break detection method comprising:
The wire break detection method of claim 15, further comprising controlling the self-propelled device to walk along the boundary wire and determining that a position of the boundary wire where the self-propelled device is located is a wire break position when the amplitude of the boundary wire inductive signal is less than or equal to a second predefined threshold.
