Description

Technical Field

[0001] The present invention relates to the technical field of intelligent storage management, and in particular to an intelligent three-dimensional storage system for a transformer assembly line. Background Art

[0002] In modern manufacturing, especially in the production line of electrical equipment such as transformers, material management and transportation are key factors affecting production efficiency and cost control. Traditional warehousing systems generally rely on manual operations, such as material warehousing, outbound, inventory, and production line distribution, which are not only time-consuming and labor-intensive, but also prone to errors, resulting in low production efficiency and high warehousing costs. In addition, traditional warehousing systems often adopt a flat layout with low space utilization, which makes it difficult to meet the growing demand for material storage.

[0003] In response to the above problems, the industry has begun to explore intelligent and automated warehousing solutions. However, although the intelligent warehousing systems in the existing technology have achieved automated management and transportation of materials to a certain extent, they still have many shortcomings. For example, some intelligent warehousing systems can only achieve simple identification and classification of materials, and cannot track the quantity and location changes of materials in real time, resulting in delayed and inaccurate material management information.

[0004] In addition, the scheduling systems of existing intelligent warehousing systems are mostly based on preset rules or simple algorithms, lacking the ability to process real-time data and dynamically plan routes. When production line demand changes, these systems are often unable to quickly adjust the material delivery path and speed, causing the production line to stop waiting for materials or material accumulation, affecting the flexibility and response speed of the production line. Summary of the invention

[0007] Beneficial effects of the basic solution: Multifunctional three-dimensional shelves can store more materials while reducing floor space; the material identification device can automatically identify the type, quantity and location information of the material, reducing the time for inventory and recording, and improving the accuracy and efficiency of warehouse management. The intelligent scheduling subsystem receives and analyzes the real-time data of the material and the production needs of the production line in real time through the data processing module, and can respond quickly to adjust the material transportation path and speed; the automated conveying subsystem can quickly and accurately transport materials from the material incoming area to the production line according to the instructions of the intelligent scheduling subsystem.

It will be understood that the specific embodiments described herein are only partial embodiments of the present invention, which are only used to explain the present application, rather than to limit the present application. It should be noted that the technical features or combinations of technical features described in the following embodiments should not be considered isolated, and they can be combined with each other to achieve better technical effects. The same reference numerals appearing in the drawings of the following embodiments represent the same features or components, which can be applied to different embodiments.

[0019] In addition, unless otherwise defined, the technical terms or scientific terms used in the description of the present invention should have the common meanings understood by those skilled in the art in the art to which the present invention belongs.

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings: Embodiment 1 Reference Figure 1 , an intelligent three-dimensional storage system for transformer assembly lines, including material incoming area, automated conveying subsystem, intelligent scheduling subsystem, and monitoring subsystem.

[0021] The material incoming area includes multifunctional three-dimensional shelves, material identification devices, and storage and retrieval devices.

[0022] The number of layers of the multifunctional three-dimensional shelves can be flexibly adjusted according to the type and quantity of materials. Each shelf is equipped with a material tray to carry the raw materials, semi-finished products and finished products required for transformer production. The shelves are equipped with tracks and conveyor belts to facilitate the quick storage and retrieval of materials.

[0023] The material identification device is used to identify the type, quantity, batch and location information of the material, and upload it to the intelligent scheduling subsystem to provide data support for the automatic scheduling of materials. The material identification device is installed above or on the side of each storage unit of the multifunctional three-dimensional shelf, specifically an RFID reader, barcode scanner and / or high-definition camera, which is used to identify the type, quantity and batch of the material. The storage unit can be a separate layer of the multifunctional three-dimensional shelf, or a separated grid in a layer.

[0024] The storage and retrieval device includes a stacker and a shuttle, which are used to quickly store and retrieve materials on the shelf. The stacker is responsible for taking materials from the top or bottom layer of the shelf, and the shuttle is responsible for moving materials within the same layer of the shelf.

[0025] Automated conveying subsystem, used to transport materials from the material incoming area to the production line, and to transport finished products from the production line to the storage area, including conveyor belts, AGV (automatic guided vehicle), KBK (suspension crane), RGV (ring track vehicle), etc.

[0026] Conveyor belts are used to connect the material conveying path between the material incoming area and the production line. According to the layout and requirements of the production line, the conveyor belt can be designed as a straight line, a curve or a branch type to meet the needs of different material conveying.

[0027] AGV can automatically travel on a specified path to transport materials from the incoming material area to the production line, or to transport finished products from the production line to the storage area. AGV is equipped with a material tray to carry materials. Through the built-in navigation system and obstacle avoidance sensors, AGV can identify paths and obstacles to achieve safe and efficient material handling.

[0028] KBK is used to transport heavy materials between the material storage position of the shelf, the work station of the production line and the material collection position of the AGV. The hook of KBK can be customized according to the shape and size of the material to ensure the stability of the material during the handling process. The action of KBK is controlled by the automatic conveying subsystem to realize the automatic handling and precise positioning of the material.

[0029] RGV is used to quickly transport materials within a production line or between different production lines. The RGV is equipped with a material tray to carry materials. Through the circular track, the RGV can transport materials between different workstations and improve the overall efficiency of the production line.

[0030] The intelligent scheduling subsystem includes data processing module, path planning module, scheduling execution module, etc.

[0031] The data processing module is used to receive real-time data of materials and process and analyze the data. The real-time data of materials includes the type, quantity, batch and location information of materials and the production requirements of the production line.

[0032] The path planning module is used to plan the transportation path from the material incoming area to the production line based on the real-time data of the materials. The path planning algorithm comprehensively considers factors such as the type, quantity, batch, location information of the materials, and the performance and status of the conveying equipment to ensure that the materials can be transported to the production line in the shortest time, at the lowest cost, and with the highest efficiency.

[0033] The scheduling execution module is used to convert the path planning results into specific transportation control instructions and send them to the automated transportation subsystem.

[0034] The monitoring subsystem is used to monitor the operating status and performance parameters of the intelligent three-dimensional storage system in real time to ensure the safe and stable operation of the system, including video monitoring modules, sensor networks, alarm modules, etc.

[0035] The video monitoring module is used to monitor the operation status of the storage system and the material transportation process in real time through cameras installed in key areas. Through the video images, operators can intuitively understand the actual situation of the storage system and discover and deal with potential problems in a timely manner.

[0036] The sensor network includes sensors distributed in various areas of the storage system, which are used to monitor the system's key parameters such as temperature, humidity, vibration, etc. Through the sensor network, operators can understand the environmental status of the storage system in real time and ensure that materials are stored and transported under appropriate conditions.

[0037] The alarm module is used to send out alarm signals in time when the storage system is abnormal or fails. The alarm signal can be sent to operators and managers through sound and light alarms, SMS alarms, email alarms, etc., so that measures can be taken quickly to solve the problem. At the same time, the alarm system can also record historical information of abnormalities or failures to provide data support for system maintenance and optimization.

[0038] Embodiment 2 The technical feature that distinguishes this embodiment from the above-mentioned embodiment is that the high-definition camera further includes an image processing module. The high-definition camera is used to capture material images, and the image processing module is used to pre-process the images and perform feature extraction and classification recognition on the pre-processed images through a recognition algorithm. When materials enter the multifunctional three-dimensional shelf or material shelf warehouse, the high-definition camera will capture the material image and transmit it to the image processing module for preprocessing. The preprocessed image is input into the recognition algorithm, which recognizes the material according to its characteristics and outputs the recognition results of the material type, specification and quantity.

[0039] The multifunctional three-dimensional shelf will summarize material information such as inventory quantity, location, practical status, etc. based on the identification results, adjust the distribution strategy according to the material information, optimize the material storage location according to the material demand, and prepare materials in advance to adjust the distribution route.

[0040] The multifunctional three-dimensional shelves will optimize the storage location of materials according to their practical frequency, types, and specifications. According to the frequency and trend of material use, the storage location will be dynamically adjusted to reduce material handling time.

[0041] The multifunctional three-dimensional shelf will generate material supply trends based on historical material warehousing information, and predict material production demand trends based on material information. It will collect historical material warehousing information, including key data such as material type, specification, quantity, and warehousing time. It will use big data analysis technology to conduct in-depth mining of historical material warehousing data to identify the regularity and periodicity of material supply. Based on the data analysis results, the system can generate material supply trends and predict the material supply volume and delivery time in the future.

[0042] Obtain production plan information, including production batches, production quantities, required material types and specifications. Based on the production plan information and material supply trends, predict the production demand trend of materials in the future, including the types, specifications, quantities and time nodes of the required materials.

[0043] The multifunctional three-dimensional shelf takes out relevant materials from the inventory in advance according to the production demand trend forecast results and places them in the designated preparation area.

[0044] Afterwards, the material warehousing demand trend is predicted based on the material production demand trend and inventory analysis, and a material requirement list is automatically generated to guide the purchase or processing of redundant materials and optimize material inventory.

[0045] Embodiment 3 The technical feature that distinguishes this embodiment from the above-mentioned embodiments is that a uniquely identified RFID tag is bound to each material, and the RFID tag is affixed in a conspicuous position.

[0046] The RFID reader reads the RFID tag information of materials passing by it, collects data in real time, and generates material tracking records based on the material number, reading time, reading location and other information in the tag information, including the material's movement path and timestamp.

[0047] The intelligent scheduling subsystem counts the frequency of each path being used and identifies high-frequency paths.

[0048] Analyze the movement of materials over different time periods to identify peak and trough periods.

[0049] By combining the path frequency and time distribution, the bottleneck path in the material flow process is identified. The bottleneck path is characterized by high frequency and high time consumption.

[0050] Compare the movement paths of different materials and identify similar paths through clustering algorithms; calculate the material movement efficiency and time cost of each path and identify inefficient paths; combine path comparison and efficiency evaluation to identify redundant paths, that is, paths that can be replaced by shorter or more efficient paths.

[0051] The warehouse layout is abstracted into a graph structure, where nodes represent shelf locations or exits, edges represent paths, and edge weights represent moving distances or time.

[0052] The optimization algorithm is used to calculate the path for the bottleneck path or redundant path corresponding to the material to reach the outbound port, including the following: Set the initial temperature T o , the initial solution is set as the bottleneck path or redundant path, and the number of iterations is set.

[0053] Based on the current solution, a new solution is generated by randomly exchanging the node order or inserting / deleting nodes, creating a taboo table, and adding the path currently in use to the taboo table to avoid duplication between the new solution and the existing path.

[0054] Accept the new solution with a certain probability, and if the new solution is better than the current solution, accept it unconditionally; If the new solution is worse than the current solution, it is accepted with the following probability:

[0055] in, is the difference between the new solution and the current solution, T n is the current temperature.

[0056] The temperature is gradually lowered. At each temperature, the new solution generation is repeated. It is determined whether to accept the new solution and the temperature is updated until the set number of iterations L is reached or the termination condition is met. The bottleneck path or redundant path corresponding to the initial solution is replaced by the new path.

[0057] Other bottleneck paths or redundant paths can be continuously monitored and calculated, and the paths can be optimized.
