Intelligent warehousing system and control method thereof

Abstract

The invention discloses an intelligent warehousing system. The intelligent warehousing system comprises a high-altitude four-way storage area on the upper layer, a low-altitude AGV storage area on thelower layer, four-way shuttle vehicles and AGVs, wherein a plurality of high-altitude storage units are stored in the high-altitude four-way storage area, the high-altitude four-way storage area is provided with a warehouse input and output area, and the high-altitude storage units can enter or exit from the high-altitude four-way storage area through the warehouse input and output area; a plurality of shelves are stored in the low-altitude AGV storage area, a replenishment area is arranged in the low-altitude AGV storage area, the high-altitude storage units can be transported into the replenishment area so as to replenish one or more shelves with goods; the four-way shuttle vehicles run in the high-altitude four-way storage area so as to transport the high-altitude storage units; the AGVs run in the low-altitude AGV storage area so as to transport the shelves.

Description

technical field [0001] The invention relates to the field of intelligent storage, in particular to an intelligent storage system including a high-level four-way storage area and a low-level AGV storage area and a control method thereof. Background technique [0002] In the warehousing system and logistics transportation links, more and more automatic guided vehicles (AGV) have been used to replace or supplement manual labor. The automatic guided vehicle can automatically receive the item handling task. Under the control of the program, it reaches the first position, gets the item, then walks to the second position, unloads the item, and continues to perform other tasks. [0003] The existing latent AGV carries the shelves to the picking workstation, so as to realize the picking operation mode of goods to people. Due to reasons such as safety and convenience of picking operations, the height of the AGV carrying the shelf generally does not exceed 2.5m; therefore, for the gen...

AI Technical Summary

Problems solved by technology

Due to reasons such as safety and convenience of picking operations, the height of the AGV carrying the shelf generally does not exceed 2.5m; therefore, for the general AGV warehouse where the goods arrive at the person, the space utilization rate of the warehouse is generally low

[0004] In addition, for the goods-to-person AGV warehouse, the source of goods replenishment in the AGV storage area generally needs to be transferred from other goods storage areas to the replenishment point of the AGV warehouse for replenishment, and special personnel are required to transfer the replenishment of the AGV warehouse area Operation

At the same time, it is necessary to reserve a replenishment channel in the warehouse, which wastes the available area of ​​the warehouse
