AGV warehouse management system, AGV scheduling method and storage device

Abstract

The invention provides an AGV warehouse management system, an AGV scheduling method and a storage device, the AGV warehouse management system comprises a plurality of shelves, tow bar trays, an AGV scheduling subsystem and a main controller, the shelves are provided with a plurality of storage positions for placing the trays, each storage position is provided with a card reader, and each card reader is correspondingly provided with a different ID number; the trays are used for placing goods, an intelligent card is embedded in each tray, and various information of the corresponding goods is stored in each intelligent card; the main controller is in communication connection with the card reader and the scheduling subsystem. The card reader reads the intelligent cards of the trays on the storage positions in real time and feeds back the read information to the main controller, the main controller sends the obtained goods information on the goods shelf to the dispatching subsystem to be stored, and when the goods are delivered out of the warehouse, the dispatching subsystem inputs the goods information to control AGVs to reach the corresponding storage positions to take the goods; whenthe AGVs are delivered out of the warehouse, the AGVs can be controlled to be stored in the corresponding storage position by selecting the idle storage position in the scheduling subsystem.

Description

technical field [0001] The invention relates to the technical field of AGV scheduling systems, and mainly relates to an AGV warehouse management system, an AGV scheduling method and a storage device. Background technique [0002] In the context of Industry 4.0, AGVs are increasingly used in smart logistics factories. In the current AGV storage scheduling system, many scheduling systems will install a card reader on the AGV forklift, which requires the AGV forklift to plan the location path of access through complex algorithms, but it is impossible to obtain the situation on the shelf in real time. Conflicts when goods are put in or out of the warehouse cannot avoid some misoperations that may be caused in actual production operations; in addition, in the current AGV warehousing scheduling system, the operator knows the location of the goods in advance and sets it in the scheduling system The specific shelf coordinate position that the AGV wants to reach, so as to realize th...

Problems solved by technology

In the current AGV warehouse dispatching system, many dispatching systems will install card readers on the AGV forklift, which requires the AGV forklift to plan the location path of access through complex algorithms, but cannot obtain the situation on the shelf in real time, which is easy It is impossible to avoid possible misoperations in some actual production operations when conflicts occur when goods enter or exit the warehouse. In addition, in the current AGV storage scheduling system, the operator knows the location of the goods in advance and sets them in the scheduling system. The specific shelf coordinate position that the AGV wants to reach, so as to realize the access of goods

However, this storage method has the following disadvantages: it is necessary to know the specific shelf location of the goods. If the operator is not familiar with the warehouse, there is no way to accurately obtain the location of the goods in a short time, which will affect the AGV forklift to pick up the goods. In addition, the goods are tied to the shelf position. That is, the goods must be placed on the designated position of the shelf, otherwise when the operator cannot know the change of the position of the goods in time or the dispatching system cannot realize the real-time update of the shelf position information, it is easy to pick up the wrong goods, which greatly reduces the efficiency, and because The position of the goods and the shelf is bound, and the storage of the goods cannot be adjusted conveniently. In special cases, the utilization rate of the shelf cannot be increased
