Description

Technical Field

[0001] This utility model relates to the field of warehousing and logistics technology, specifically to an automated three-dimensional warehouse with multi-device collaborative control. Background Technology

[0002] With the rapid development of the logistics industry, automated storage and retrieval systems (AS / RS) have been widely used due to their advantages such as efficient space utilization and improved warehousing efficiency. However, existing AS / RS typically manage warehousing equipment using a single control system, such as controlling stacker cranes and conveyor belts through a central control console. This single control method has many drawbacks. When the central control system malfunctions, the entire AS / RS may be paralyzed, severely impacting normal warehousing operations. Furthermore, the coordination between different devices is poor, making it difficult to flexibly adjust operating status according to actual working conditions, resulting in low operational efficiency. In addition, existing AS / RS mostly use wired communication, which involves complex wiring, high costs, and hinders flexible equipment movement and expansion. Some AS / RS using wireless communication have weak communication stability and anti-interference capabilities, easily experiencing data transmission delays or losses, affecting the accuracy of collaborative control. Therefore, we propose a multi-device collaborative control AS / RS. Utility Model Content

[0003] In view of the problems existing in the current multi-device collaborative control automated three-dimensional storage, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a multi-device collaborative control automated storage and retrieval system (AS / RS). This addresses the problem that existing AS / RS typically manage storage equipment using a single control system, such as controlling stacker cranes and conveyor belts solely through a central control console. However, this single control method has many drawbacks. When the central control system malfunctions, the entire AS / RS may be paralyzed, severely impacting normal warehousing operations. Furthermore, the coordination between different devices is poor, making it difficult to flexibly adjust operating states according to actual working conditions, resulting in low operational efficiency. Additionally, existing AS / RS mostly use wired communication for equipment communication, which involves complex wiring, high costs, and hinders flexible equipment movement and expansion. Some AS / RS using wireless communication suffer from weak communication stability and anti-interference capabilities, easily experiencing data transmission delays or losses, affecting the accuracy of collaborative control.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automated storage and retrieval system (AS / RS) with multi-device collaborative control includes an AS / RS racking system, various types of storage equipment, a central control module, a main communication module, a backup communication module, and a central monitoring platform. Various types of storage equipment, including stacker cranes, shuttle cars, and AGV robots, are installed on one side of the AS / RS racking system. The central control module is communicatively connected to an area control module, and the area control module is communicatively connected to a local device control module. The main communication module is a 5G communication module, and the backup communication module is a LoRa wireless communication module. Both the main and backup communication modules are electrically connected to the central control module, the area control module, and the local device control module.

[0007] Preferably, the central monitoring platform is electrically connected to the central control module.

[0008] Preferably, the automated shelving unit is equipped with a cargo identification device on one side, which is an RFID reader / writer.

[0009] Preferably, the stacker crane, shuttle car and AGV robot are all fixedly equipped with positioning and navigation devices, which are a combination of UWB positioning devices and laser navigation devices.

[0010] Preferably, the device's local control module is connected to an emergency control module.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0012] 1. This utility model adopts a three-level control architecture consisting of a central control module, regional control modules, and local equipment control modules. The central module is responsible for overall planning, the regional modules manage the equipment in their respective zones, and the local modules directly control individual devices. When a regional module or the central module fails, other regions can maintain basic operations through their local modules, avoiding overall paralysis and significantly reducing the impact of failures on warehousing operations. Furthermore, the three-level control architecture enables hierarchical scheduling. The central module formulates a global task plan based on the storage requirements of the goods, and the regional modules allocate tasks to specific local equipment modules based on the load and status of the equipment within their respective zones.

[0013] 2. This utility model employs a dual-link design with a main communication module and a backup communication module. The 5G module enables high-speed, low-latency data transmission to meet real-time control requirements, while the backup communication module boasts strong anti-interference capabilities and wide coverage. When the 5G signal is blocked or malfunctions, it automatically switches to the backup communication link to ensure uninterrupted control commands and status data. Furthermore, the wireless communication architecture eliminates the need for complex wiring, allowing for flexible addition of equipment and reducing expansion costs. Additionally, RFID readers are installed on the automated shelving system to quickly read cargo tag information and transmit it to the central module via the regional modules, enabling precise cargo classification and scheduling and avoiding errors from manual identification.

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] This utility model discloses an automated three-dimensional warehouse with multi-device collaborative control.

[0021] This utility model provides, for example Figure 1-2 The illustrated automated storage and retrieval system (AS / RS) with multi-device collaborative control includes an AS / RS rack 1, various types of storage equipment 2, a central control module 3, a main communication module 4, a backup communication module 5, and a central monitoring platform 6. The AS / RS rack 1 has various types of storage equipment 2 on one side, including a stacker crane 7, a shuttle car 8, and an AGV robot 9. The central control module 3 is communicatively connected to an area control module 10, and the area control module 10 is communicatively connected to a local device control module 11. The main communication module 4 is a 5G communication module, and the backup communication module 5 is a LoRa wireless communication module. Both the main communication module 4 and the backup communication module 5 are electrically connected to the central control module 3, the area control module 10, and the local device control module 11, achieving hierarchical control of the AS / RS and improving equipment collaboration and operational efficiency.

[0022] This utility model relates to an automated storage and retrieval system with multi-device collaborative control. The central monitoring platform 6 is electrically connected to the central control module 3 and is used to display the overall operating status of the automated storage and retrieval system, the operating parameters of each storage device, and the storage information of the goods in real time.

[0023] This utility model relates to a multi-device collaborative control automated storage and retrieval system. The automated storage and retrieval system 1 is equipped with a cargo identification device 12 on one side. The cargo identification device 12 is an RFID reader / writer used to identify cargo information and transmit the identified information to the central control module 3 through the area control module 10, so that the central control module 3 can accurately manage and schedule the cargo.

[0024] This utility model discloses an automated storage and retrieval system with multi-device collaborative control. The stacker crane 7, shuttle car 8, and AGV robot 9 are all fixedly equipped with positioning and navigation devices 13. The positioning and navigation devices 13 are a combination of UWB positioning devices and laser navigation devices, which improves the positioning accuracy and navigation stability of the equipment and ensures that the equipment operates accurately in the automated storage and retrieval system.

[0025] This utility model discloses an automated three-dimensional warehouse with multi-device collaborative control. The local control module 11 of the equipment is connected to an emergency control module 14. When an emergency occurs in the storage equipment, the emergency control module 14 can directly send instructions to the local control module 11 of the equipment to control the equipment to stop urgently or take other emergency measures to ensure the safety of the equipment and goods.

[0026] During operation, managers input warehousing operation requirements through the central monitoring platform 6. The central monitoring platform 6 converts the requirements into data signals and transmits them to the central control module 3. The central control module 3, in conjunction with the overall inventory status of the automated warehouse and the equipment load in each area, formulates a global task plan. Then, the central control module 3 transmits the task instructions to the area control module 10 through the 5G main communication module 4. After receiving the instructions, the area control module 10 analyzes the equipment status in that area and breaks down the task into sub-tasks: the stacker crane 7 takes goods from the shelf and sends them to the stacker crane 7 local control module; the AGV robot moves the goods from the stacker crane 7 to the conveyor belt and sends them to the AGV robot local control module; the conveyor belt transports the goods to the sorting area and sends them to the conveyor belt local control module. If 5G communication is interrupted, it automatically switches to the LoRa backup communication module 5 to ensure normal command transmission. After receiving the sub-task command, the local control module 11 of each device drives the device to execute the operation. The stacker crane 7 navigates to the shelf using UWB and laser positioning, and retrieves the goods after confirming the goods information with the RFID reader. The AGV robot moves synchronously to the position of the stacker crane 7, receives the goods, and then drives to the conveyor belt according to the navigation path. The conveyor belt adjusts its running speed according to the arrival time of the AGV robot. After receiving the goods, it transports them to the sorting area. At the same time, each local control module collects the equipment operating status in real time and feeds it back to the area control through the dual communication modules. Module 10, after being aggregated by the regional modules, transmits the data to the central control module 3 and the central monitoring platform 6. Management personnel can view the task progress and equipment status in real time through the monitoring platform. If a device malfunctions, the device's local control module 11 immediately transmits the abnormal signal to the emergency control module 14. The emergency control module 14 sends instructions directly to the local control module without going through the regional or central modules, and simultaneously feeds back the abnormal information to the central monitoring platform 6 to remind management personnel to handle the issue. After the fault is resolved, management personnel issue a resumption command through the monitoring platform. After transmission through the central, regional, and local module levels, the device resumes its task.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
