PURPOSE:To improve the operation efficiency of respective unmanned carrier vehicles while securing high safeness by selecting one halt signal transmission part corresponding to either one of two unmanned carrier vehicle detecting parts which detects the passage of either one of unmanned carrier vehicles, and allowing the other halt signal transmission part to output a halt signal until a prescribed condition is arranged. CONSTITUTION:The system is constituted of a ground side equipment 1 and halt signal receivers 3 mounted on respective unmanned carrier vehicles 2a, 2b to allow the vehicle 2a traveling the main line side to enter a confluent point without halting it other than the case the vehicle 2b traveling the branch side enters into the confluent point prior to the vehicle 2a. When the passage of the unmanned carrier vehicle is detected either one of two unmanned carrier vehicle detecting parts 6a, 6b arranged on respective traveling routes, a control part 8 selects one halt signal transmission part corresponding to the detecting part 6a or 6b and allows the other halt signal transmission part to output a halt signal until the prescribed condition is arranged. Thus, the operation efficiency of respective unmanned carrier vehicles 2a, 2b can be improved while securing high safeness. |
