Of the area wire for unmanned work vehicle arrangement and its control device

摘要

PROBLEM TO BE SOLVED: To provide an arrangement structure of an area wire for an unmanned traveling working vehicle or the like arranged to reduce a travel distance with a simple structure when the unmanned traveling working vehicle returns to a charger for battery charging and to improve work efficiency in a control device for the unmanned traveling working vehicle that is mounted on a vehicle body and is arranged to drive a working machine by an electric motor supplied with power from a battery and to cause the working machine to operate.;SOLUTION: An unmanned traveling working vehicle is provided with electric motors supplied with power from a battery mounted and is arranged to drive a working machine, blade, to operate while traveling in a working area 70 defined by an area wire 72. The unmanned traveling working vehicle is further arranged to detect magnetic field intensity of the area wire 72 and to return to a charging station 74 having a charger 84 disposed on the area wire 72 for battery charging. The area wire 72 is folded back towards a charger detection area 76a with a predetermined separation space at any position and a fold back portion 72a is formed so as to allow the working area 70 to be cut off into a plurality of zones, two zones.;COPYRIGHT: (C)2013,JPO&INPIT
