Document Type and Number:
WIPO Patent Application WO/2013/177919
Kind Code:
A1
Abstract:
A working area definition and guidance method for controlling an automatic device (2) and a system thereof. The system comprises a signal generation system (8) arranged on the automatic device (2), and a signal receiving system (3). The signal generation system (8) generates a magnetic field signal with the movement of the automatic device (2), and propagates same through the air; the signal receiving system (3) is connected to a cable (1), and the signal receiving system (3) detects at least one static or alternating magnetic field generated by the signal generation system (8) within a specific time; and the signal receiving system (3) transmits a processing signal to the automatic device (2) according to the magnetic field signal. The system has the advantages that the magnetic field signal generated by the signal generation system (8) does not need a specific frequency and phase relationship; the signal receiving system (3) can be conveniently extended to connect a plurality of closed cable loops, thereby subdividing a working area, so as to provide guidance information for the movement of the automatic device (2) among different areas; and a plurality of closed loops formed by the cable (1) can mutually cover and cross.
