Embodiment
[0052] This embodiment provides a multi-vehicle scheduling method for four-way shuttle vehicles in multi-depth storage areas, the steps are as follows:
[0053] Step (1), obtain the infrastructure information of the multi-depth storage area, and obtain the traffic network rules. The infrastructure information of the multi-depth storage area is as follows: figure 2 , including the location information of the cargo location and the location information of the storage roadway, etc.:
[0054]Traffic operation rule 1: At the intersection of multi-deep shipping lanes, use the locking strategy of intersection use rights to avoid intersection conflicts. When two four-way shuttle vehicles pass through the intersection at the same time, they both need to apply for the right to use the intersection node, and only one four-way shuttle vehicle can obtain the right to use at the same time. After the first four-way shuttle vehicle passes the intersection, the next vehicle In order to obtai...

The invention relates to a multi-vehicle scheduling method of four-way shuttle vehicles in a multi-depth storage area. The method comprises following steps: S1, obtaining a traffic network rule of themulti-depth storage area based on infrastructure information of the multi-depth storage area; S2, performing traffic network orientation of the multi-depth storage area by employing a graph theory based on the traffic network rule; S3, obtaining information of goods allocation of the multi-depth storage area and the four-way shuttle vehicles of storage roadways based on a traffic network orientation result; and S4, performing task exchange and adjacent-road passing among the four-way shuttle vehicles based on the information of the goods allocation of the multi-depth storage area and the four-way shuttle vehicles of the storage roadways to realize multi-vehicle scheduling of the four-way shuttle vehicles. Compared with the prior art, multiple vehicles can operate at the same time, and thework efficiency of the whole warehousing system is improved.
Description
technical field [0001] The invention relates to the field of dispatching of four-way shuttle vehicles in storage systems, in particular to a multi-vehicle dispatching method for four-way shuttle vehicles in multi-depth storage areas. Background technique [0002] The high-density storage system consists of elevators, four-way shuttles, multi-depth shelves and storage management systems. The four-way shuttle car realizes the round-trip transportation of goods from the hoist at the entrance of the single layer to the target cargo location, and the hoist transfers the goods between the first floor and the multi-layer and realizes the layer change of the four-way shuttle car. The multi-depth storage area is composed of multi-layer racks. The layout of different layers in the same multi-layer rack is the same, and it is composed of multiple multi-depth storage lanes that can store multiple goods. The warehouse management system can monitor the status of four-way shuttle vehicles...
