Title:
REMOTE OPERATION SYSTEM FOR WORK VEHICLE
Document Type and Number:
Japanese Patent JP3508878
Kind Code:
B2
Abstract:
PURPOSE: To perform the work of a working vehicle safely extending over from a dangerous area to a deep working site by performing the remote operation of the work from a base station on a personal link line by millimeter wave communication after moving a mobile communication relay vehicle to a working site by SS radio.
CONSTITUTION: The delivery of working machines 5 to 15 in the working site is performed by transmitting an operating signal from the SS radio equipment 45 of an SS relay vehicle 3 to the working machines 11 to 15 and the mobile communication relay vehicle 5 when the operating signal from a control room 1 is transmitted to the relay vehicle 3 on the personal link line formed with millimeter wave communication units 25, 37. The machines 5, 11 to 15 are moved to a dangerous boundary line K by receiving a remote control operation, and they arrive at the site G as breaking a road by the machines 7, 9. Thence. when the relay vehicle 5 arrives at a prescribed place in the site G. the remote operation of the antenna 33 of the relay vehicle 5 to direct the millimeter wave communication unit 31 of the room 1 is performed. When four personal link lines formed with the relay vehicle 5 and the units 39, 31 of the room 1 become available. the remote operation can be performed on those lines.
