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...

Abstract

The present invention relates to a multi-vehicle scheduling method for four-way shuttle vehicles in a multi-depth storage area, comprising: step S1: obtaining the traffic network rules of the multi-depth storage area based on the infrastructure information of the multi-depth storage area; step S2: based on the traffic network Rule, use graph theory to carry out the traffic network orientation of multi-depth storage area; Step S3: Based on the traffic network orientation results, obtain the information of goods in the multi-depth storage area and the four-way shuttle vehicle in the storage roadway; Step S4: Based on the multi-depth The goods in the storage area and the four-way shuttle vehicle information in the storage roadway, the task exchange between the four-way shuttle vehicle and multi-vehicles, and the passage through the road to realize the four-way shuttle vehicle multi-vehicle scheduling. Compared with the existing technology, it ensures that multiple vehicles can run at the same time and improves the working efficiency of the entire storage system.

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...
