Abstract:
1. A transporting system comprising: a track having first track portion, a second track portion and a junction point to which the first track portion and second track portion are mutually joined; a plurality of transporting vehicles, each travelling on said track; and a transferring device comprises (i) a first guide wire disposed on a left side of the first track portion and to a right side of the second track portion with respect to a travelling direction of each transporting vehicle as a standard and (ii) a second guide wire disposed on a right side of the first track portion to a left side of the second track portion with respect to a travelling direction of each transporting vehicle as the standard and the transferring device can transfer a signal through said first guide wire and second guide wire, each of said transporting vehicle comprising: a transmitting device for transmitting the signal through one of the first guide wire and the second guide wire, in order to prevent collision at the junction point and the transmitting device disposed on an edge of a one side with respect to a travelling direction of each transporting vehicle as the standard; a first receiving device for receiving the signal transmitted by the transmitting device, and the first receiving device disposed on an edge of an other side with respect to a travelling direction of each transporting vehicle as the standard; and a second receiving device for receiving the signal transmitted by the transmitting device in order to confirm a transfer operation through said transferring device and disposed on the edge of the one side with respect to a travelling direction of each transporting vehicle as the standard, the transporting system further comprising: a detecting device for detecting said transporting vehicle's entering the junction point; a transmission controlling device for controlling the transmitting device to transmit the signal upon the entering being detected; a judging device for judging that the transfer operation is abnormal upon the entering being detected and upon the second receiving device failing to receive the signal; and a travel controlling device for controlling said transporting vehicle to stop (i) upon the first receiving device receives the signal, said transporting vehicle comprising the first receiving device that receives the signal; and (ii) upon judging that the transfer operation is abnormal, said transporting vehicle comprising the second recovering device failing to receive the signal.
