PROBLEM TO BE SOLVED: To prevent an unmanned carrier from traveling off its course through an unmanned carrier travel system in which the unmanned carrier travels along a travel line through image recognition.SOLUTION: A travel line 20 using tapes comprises a main track 20A and an auxiliary track 20B on one side or both sides of the main track 20A. The automatic guided vehicle 10 acquires an outline by imaging the travel line 20 (main track 20A and auxiliary track 20B) by a USB camera 12. A center value of the outline is obtained. A moving direction is determined according to a position (corresponding to coordinates) and an angle of the center value on a screen. A PLC is connected to an elevator 1 control board for an elevator to communicate with a server PC. The PLC and an elevator PLC control PC are connected to an elevator 2 control board of the elevator to communicate with the server PC. The unmanned carrier 10 and the server PC communicate, and the unmanned carrier 10 elevates/lowers with respect to the elevator. |
