<p>PURPOSE:To energy-save by turning OFF a power source supply except a control unit when a standby state which does not receive an operation command continues for the prescribed time. CONSTITUTION:A microcomputer 10a of a control unit 10 of an operatorless conveying vehicle turns OFF a power source supply to a drive unit 11 and a sensor 13 except a control unit 10 when an operation command from a station is not received for the prescribed time. On the other hand, when received, it analyzes the content of its command, turns ON the power source to a travel control related units when the content is a travel command to execute the command, and turns ON the power source to a transfer control related units when it is a transfer command to execute the command. Thus, the power consumption of a battery is restricted to the least limit as required to raise the energy-saving effect.</p> |
