ABSTRACT:
A transport control apparatus for a plurality of automated guided vehicles traveling a transport path having a confluence junction, a turnout or a crossing is comprised of a conductor of a loop-shaped configuration formed to surround the confluence junction, the turnout or the crossing, a magnetic field generating device provided on each of the plurality of automated guided vehicles and generating a magnetic field having a cycle peculiar to each of the automated guided vehicles, a magnetic field detecting device provided on each of the plurality of automated guided vehicles and detecting a magnetic field, wherein when the magnetic field detecting device of a rear automated guided vehicle detects a magnetic field from the loop-shaped conductor induced by the magnetic field generating device of a front automated guided vehicle, the rear automated guided vehicle is halted.
