Abstract
A transporting vehicle system includes a prohibited travel zone setter that sets a first prohibited travel zone where entry of a travelling vehicle is prohibited, an additional prohibited travel zone setter that sets a second prohibited travel zone upstream of the first prohibited travel zone according to rules, and a transporting vehicle controller that controls a transporting vehicle to prevent the vehicle from entering the first prohibited travel zone or the second prohibited travel zone.

1-6. (canceled)
A transporting vehicle system comprising:
- a plurality of transporting vehicles capable of traveling along a route including node points that include branch points where the route branches off and merge points where the route merges into, and zones located between the node points;
- a first prohibited travel zone setter that sets a first prohibited travel zone that is one of the zones where entry of the transporting vehicles is prohibited;
- a second prohibited travel zone setter that sets a second prohibited travel zone upstream of the first prohibited travel zone according to rules;
- and
- a transporting vehicle controller that controls the transporting vehicles to prevent the transporting vehicles from entering the first prohibited travel zone or the second prohibited travel zone;
- wherein
- the rules include:
- a rule that, if one of the node points upstream of the first prohibited travel zone is one of the merge points, all of the zones that merge into the one of the merge points are set as additional prohibited travel zones;
- and
- a rule that, if one of the node points upstream of the first prohibited travel zone is one of the branch points and all of the zones branching off from the one of the branch points are the additional prohibited travel zones, one of the zones upstream of the one of the branch points is set as one of the additional prohibited travel zones.
A method of controlling a transporting vehicle system including transporting vehicles capable of traveling along a route including node points that include branch points where the route branches off and merge points where the route merges into, and zones located between the node points, the method comprising:
- setting a first prohibited travel zone that is one of the zones where entry of the transporting vehicles is prohibited;
- setting a second prohibited travel zone upstream of the first prohibited travel zone according to rules;
- and
- controlling the transporting vehicles to prevent the transporting vehicles from entering the first prohibited travel zone or the second prohibited travel zone;
- wherein
- the rules include:
- a rule that, if one of the node points upstream of the first prohibited travel zone is one of the merge points, all of the zones that merge into to the one of the merge points are set as additional prohibited travel zones;
- and
- a rule that, if one of the node points upstream of the first prohibited travel zone is one of the branch points and all of the zones branching off from the one of the branch points are the additional prohibited travel zones, the zone upstream of the one of the branch points is additionally set as one of the additional prohibited travel zones.
