PURPOSE:To exclude the feeding rails to reduce the cost of equipment by providing a microcomputer containing an optical transmitting/receiving device to a truck which is driven by the guidance of a carrier rail device and transmitting and receiving optical signals supplied from a ground control part. CONSTITUTION:A carrier truck 1 is guided by a rail device 18 of carrying equipment, and a microcomputer 26 containing the optical signal receiving and transmitting parts 24 and 25 is mounted on the truck 1. An advance command optical signal is applied to the part 24 from a ground control part and stored in the computer 26. Based on this storage of optical signal, a groping signal is transmitted from the part 25 to drive the truck 1. This groping signal is received by a fixed receiver set at the side part of a fixed route 7 and then transmitted to the ground control part. Then the control signal suppled from the ground control part is applied to a fixed transmitter at the side part of the route 7. An optical control signal is applied to the part 24 from said fixed transmitter, and the truck 1 is driven by the computer 26. In such a way, the cost of equipment is reduced. |
