UAV-based intelligent warehouse inventory system and method

Abstract

The invention provides a UAV-based intelligent warehouse inventory system and method. A warehouse space control unit is used to receive an inventory task issued by a third-party storage system, analyze the inventory task, and plan the inventory task according to the state of a UAV, so as to obtain an optimal inventory strategy; and the inventory strategy is pushed to a UAV flight control unit, andthe UAV flight control unit formulates the flight route of the UAV according to the inventory strategy and controls the corresponding UAV to perform the inventory operation. The UAV-based intelligentwarehouse inventory system and method provided by the present invention intelligently analyze and split the multi-UAV inventory tasks through the warehouse space control unit to realize seamless connection between UAV inventory and the third-party storage system, to effectively cope with the multi-UAV inventory tasks, and to meet inventory needs of large warehouses.

Description

technical field [0001] The invention relates to the technical field of intelligent warehousing, in particular to an intelligent warehousing inventory system and method based on an unmanned aerial vehicle. Background technique [0002] Warehouses are buildings and places where enterprises or individuals store items. They can be indoor buildings, specific containers, or outdoor open-air storage yards. Warehouse management is the management of warehouses and materials in warehouses. It is the management of warehouses and materials in warehouses. The process of planning, organizing, controlling and coordinating in providing efficient warehousing services with sufficient warehousing resources. Accurate warehousing management can effectively control and reduce circulation and inventory costs, which is the key support and guarantee for enterprises to maintain their advantages. [0003] Traditional warehousing management relies on manual operation and management of the warehousing, ...

Problems solved by technology

[0003] Traditional warehousing management relies on manual operation and management of the warehousing, warehousing, picking, inventory and transfer of inventory goods, which not only requires a lot of manpower, but also takes a lot of time. Not only is it inefficient, but also the data cannot be reported in real time, and There are problems such as omissions, deletions, and false positives in data; with the development of enterprise informatization, many enterprises use invoicing or professional WMS systems to manage warehouses, which solves the problem of data transfer efficiency and Statistical issues, but data collection is still a bottleneck that affects the effective use of the system and the improvement of efficiency; with the popularization of wireless handheld terminals, barcodes and RFID technologies, warehouses have very convenient and efficient means of data collection, especially in the warehouse. With the help of the batch reading function of RFID technology, it can greatly reduce the time of entering and leaving the warehouse and improve the accuracy of data. However, there has been no effective solution for the inventory inventory link. Inventory is the key link of enterprise warehouse management and financial management. In order to ensure the unity of accounts and materials, the enterprise counts the inventory materials according to the established rules within a certain period of time. The inventory results will affect the adjustment of inventory goods and financial data, so that enterprises can truly verify the financial status of inventory materials, which is of great importance to enterprise management. Meaning, the traditional warehouse inventory mainly relies on manual checks and verifications of the warehouse goods one by one according to the printed paper inventory list, and then records the summary inventory results, and then manually enters them into the computer. This method requires manual walking through every storage location in the warehouse. To check the list of goods, it is often necessary to organize a large amount of manpower to carry out inventory at a specific time, especially for goods stored on three-dimensional shelves or stacked high, it is necessary to climb with the help of escalators or other tools, and then fill in the check manually, so the inventory efficiency is very low. The labor cost is very high, and due to manual errors or other reasons, the inventory data is inaccurate, and the inventory results cannot be quickly known and targeted composite; with the emergence of barcode and RFID technology, with the help of some handheld PDAs, the inventory can be The confirmation link improves the speed and accuracy of data collection, but the overall inventory efficiency has not been improved. Later, a method of inventory taking by forklift appeared, that is, by fixing a handheld or fixed RFID reader on the forklift fork arm, through wireless transmission The method is connected with the background system. The driver drives the forklift in the middle of the shelf according to the inventory plan, and controls the fork arm to move up and down through the forklift, so as to ensure that the goods on the high-level shelves can be easily read without relying on manual climbing. This method is based on the past This reduces the work intensity of manual inventory, but it also creates a series of new problems such as temporary installation of forklift equipment, forklift and driver investment, fuel consumption, and limited driving speed. The inventory cost is too high and the input-to-production ratio is too low; With the emergence of drones, it has become a trend to carry out outdoor inspections, agricultural plant protection, and cargo handling through drones equipped with data transmission modules, cameras, and navigation systems. However, due to the particularity of the warehouse environment and operating procedures, drones Inventory there are many obstacles and difficulties

[0004] Although the UAV inventory application of the German Fraunhofer company has realized indoor autonomous navigation flight, this method relies on the deployment of a large number of visual positioning cameras indoors, which is extremely costly, cannot be applied on a large scale, and cannot effectively cope with indoor multi-UAV environments. Inventory Counting Requirements

However, Linde’s flying box is expensive due to the addition of supporting unmanned forklifts, and the speed of UAV flight and inventory is limited by the speed of AGV on the ground, which greatly limits the efficiency and potential of UAV inventory.

[0005] The UAV inventory method proposed in patent CN106934579A has no specific implementation method, and due to the lack of effective connection with the third-party storage system, it is impossible to intelligently split the UAV inventory task and effectively deal with multi-UAV inventory. In the scenario where the inventory process is abnormal, no handling method is given, especially how indoor drones can achieve precise positioning and flight without manual intervention.
