Description

Technical Field

[0001] The present invention relates to the technical field of heavy industry, and in particular to a warehouse management method, system, electronic equipment and storage medium. Background Art

[0002] In basic industries such as heavy industry, each factory still basically uses the previous warehouse management method, and carries out the warehousing and inventory work of goods through a combination of manual and paper documents. That is, the supplier delivers goods such as steel coils to the warehouse by truck. At this time, the first-line warehouse manager needs to record it in the book according to the label on the steel coil and the supplier information by hand; after recording each batch of goods, it is necessary to go to the office to submit the warehousing information to the second-line warehouse manager, who enters the information on the computer and prints out the label through a fixed printer. The first-line warehouse manager then returns to the warehouse to stick the label on the steel coil that has just been put into the warehouse and puts the steel coil in the designated location; when the steel coil that has been put into the warehouse is to be sold out of the warehouse or transferred to the warehouse, the information needs to be recorded in the book first, and then the goods are taken away and handed over to the second-line warehouse manager for entry into the system; every once in a while, the current warehouse needs to be counted. At this time, the second-line warehouse manager needs to print out the steel coil data of each warehouse, such as location and quantity. The first-line warehouse manager takes the account book to the site to check one by one. If it is found to be wrong, it needs to be recorded. After the verification, it is handed over to the second-line warehouse manager to modify the data.

[0003] The existing technology has the following disadvantages: the entry and exit of goods requires personnel to record them on paper documents and continuously pass them between the warehouse and the office. If the factory is large, this requires a lot of manpower for the entry and transfer of goods information, and it is easy to make handwriting errors or input errors due to misreading words. The inventory counting process is completely dependent on manual accuracy and is also recorded and checked manually one by one, resulting in high requirements for personnel quality and familiarity in warehouse management. Factories are generally located in remote areas, which further increases employee costs. Summary of the invention

[0017] The accompanying drawings are used to provide a further understanding of the embodiments of the present invention and constitute a part of the specification. Together with the following specific implementations, they are used to explain the embodiments of the present invention, but do not constitute a limitation on the embodiments of the present invention. In the accompanying drawings: Figure 1 It is an implementation flow chart of a warehouse management method provided by an embodiment of the present invention; Figure 2 It is a structural schematic diagram of a warehouse management system applied to a warehouse management method provided by an embodiment of the present invention; Figure 3 It is an operation flow chart of a user operating a digital twin interface on a computer provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0018] In basic industries such as heavy industry, each factory still basically uses the previous warehouse management method, combining manual and paper documents to carry out goods in and out of the warehouse and inventory work. The process is described as follows: 1. Suppliers deliver goods such as steel coils to the warehouse by truck. At this time, the first-line warehouse manager needs to record the labels on the steel coils and the supplier information in a book by hand; 2. After recording each batch of goods, you need to go to the office to submit the warehousing information to the second-line warehouse manager, who will input the information on the computer and print out the label through a fixed printer. The first-line warehouse manager then returns to the warehouse to stick the label on the steel coil that has just been put into the warehouse and put the steel coil in the designated location; 3. When the steel coils that have been put into the warehouse are to be sold out of the warehouse or transferred to another warehouse, the information must be recorded in the book first, and then after the goods are taken away, they must be handed over to the second-line warehouse manager for entry into the system; 4. Inventory counts must be done at the current warehouse every once in a while. At this time, the second-line warehouse manager needs to print out the steel coil data of each warehouse, such as location and quantity. The first-line warehouse manager takes the account book to the site to check one by one. If anything is wrong, it needs to be recorded and handed over to the second-line warehouse manager to modify the data after the check is completed.

[0019] Through the above workflow, the following problems are found: 1. The entry and exit of goods requires personnel to record them on paper documents and continuously transfer them between the warehouse and the office. In the case of a large factory, this requires a lot of manpower; 2. The entry and transfer of goods information are all written manually on paper documents, and then entered into the system by others. It is very easy to make handwriting errors or input errors caused by misreading words, which completely depends on the accuracy of manual work; 3. The inventory counting process is also recorded and checked manually one by one. Because of the problems accumulated from the previous complicated process, factories often spend a lot of time on inventory counting and proofreading data every month; 4. The above problems lead to the fact that warehouse management requires high quality and familiarity of personnel, and factories are generally in remote areas, which further leads to increased employee costs; 5. The interface of the old warehousing system is very outdated, and it is difficult for senior factory leaders to grasp the overall warehousing data of the factory based on the current system alone. The work of sorting data further consumes manpower.

[0020] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0021] See also Figure 1 As shown, it is a flowchart of an implementation of a warehouse management method provided by an embodiment of the present invention, including the following execution steps: Step 100: When the goods arrive at the warehouse, obtain the goods information and the storage location information of the current warehouse, and generate a QR code label based on the goods information and the storage location information, so that the user can perform warehouse inventory and delivery by scanning the QR code label.

[0022] Specifically, when executing step 100, the following steps may be specifically performed: S1000: Combine the acquired goods information and the storage location information of the current warehouse into a character string.

[0023] The cargo information includes but is not limited to supplier, cargo name, roll number, weight, batch and specification.

[0024] S1001: using the qrcode library and creating a two-dimensional code object, and adding the string to the created two-dimensional code object, wherein the error tolerance, pixel block size and border size of the created two-dimensional code object correspond to the content of the string.

[0025] S1002: Convert the two-dimensional code object into a PIL image, and set the foreground color and background color of the PIL image to obtain an initial two-dimensional code label.

[0026] S1003: Use a QR code scanning tool to scan the initial QR code label to generate a corresponding file. If the content in the file is consistent with the string data composed of the goods information and the storage location information of the current warehouse, the target QR code label is obtained.

[0027] In some embodiments, a mobile app is configured to integrate a portable printer, a weighing system, and an OCR recognition system. After the goods are put into storage, the mobile app scans the label, identifies the goods data, and then automatically fills in the document. Among them, the OCR system is trained for a large number of steel enterprise label samples, and supports dynamic upload of samples. New labels can also be quickly recognized. Then the goods are weighed on the weighing scale, and the weight can be directly filled in on the mobile terminal. After the document is filled, the goods are put into storage, and the warehouse-storage location is also bound to facilitate subsequent query of the goods location. For subsequent operations on the goods, the user scans the code with a handheld PDA and clicks a button to complete the operation. All operations will be stored in the system. The specific implementation is to process all goods processing requests through a message center and store them in the database. This not only ensures the timely processing of a large number of requests, but also ensures that the operation records are retained without omission. Then the system analyzes the data and decomposes it into tabular data such as in and out flow, which is convenient for users to view.

[0028] In some embodiments, the warehouse management method implementation flow chart also includes the following execution steps: the status of the goods after the user scans the QR code label to perform warehouse inventory includes any one of a no-profit-and-loss state, a damaged inventory state, and an overflow inventory state, wherein the no-profit-and-loss state is characterized by the number of goods displayed in the digital twin interface being consistent with the number of goods in the actual warehouse; the damaged inventory state is characterized by the number of goods in the actual warehouse being less than the number displayed in the digital twin interface; the overflow inventory state is characterized by the number of goods in the actual warehouse being greater than the number displayed in the digital twin interface.

[0029] Step 101: The physical environment of the warehouse and the status of the goods in the warehouse are displayed in real time through the digital twin interface.

[0030] Among them, the digital twin interface is pre-constructed using the digital twin model based on the real-time warehouse environment, warehouse capacity, storage location capacity and number of steel coils.

[0031] In some embodiments, the warehouse management method implementation flowchart also includes the following execution steps: reading the historical outbound information of goods in the digital twin interface; when the status of the goods after the warehouse inventory is changed to the damaged state and the overflow state, an early warning is issued to enable the user to query the error node according to the QR code label and the historical outbound information of the goods, and correct the current warehouse cargo quantity.

[0032] In some embodiments, the process steps of executing step 101 to simulate and construct a digital twin interface based on the warehouse real-time environment, warehouse capacity, storage capacity, and number of steel coils using the digital twin model in advance are as follows: S1010: De-noising the collected real-time warehouse environment data, warehouse capacity data, storage location capacity data, and cargo data to obtain target parameters.

[0033] S1011: Based on the warehouse's building structure, shelf layout, and equipment location information, a NURBS modeling method is used to build a proportional 3D warehouse model. The quantity and location of goods are simulated in the 3D warehouse model to ensure that the digital twin model reflects the warehouse's inventory and storage capacity in real time.

[0034] S1012: Integrate the real-time warehouse environment data, warehouse capacity data, storage location capacity data and cargo data collected in real time into the digital twin model to achieve real-time synchronization between the digital twin model and the physical warehouse.

[0035] S1013: Embedding the digital twin model on the system interface to obtain a digital twin interface.

[0036] See also Figure 2 As shown, it is a structural schematic diagram of a warehouse management system applied to a warehouse management method provided by an embodiment of the present invention, including: The QR code generation module 200 is used to obtain the cargo information and the storage location information of the current warehouse when the cargo arrives at the warehouse, and generate a QR code label based on the cargo information and the storage location information, so that the user can perform warehouse inventory and delivery by scanning the QR code label; The digital twin module 201 is used to display the physical environment of the warehouse and the status of the goods in the warehouse in real time through the digital twin interface, wherein the digital twin interface is pre-constructed using a digital twin model based on the real-time warehouse environment, warehouse capacity, storage location capacity and number of steel coils.

[0037] In some embodiments, the warehouse management system also includes an early warning module, which is used to read the historical outbound information of goods in the digital twin interface. When the status of the goods changes to the damaged state and the overflow state after the warehouse inventory, an early warning is issued to enable the user to query the error node according to the QR code label and the historical outbound information of the goods, and correct the current quantity of goods in the warehouse.

[0038] It should be noted that an alarm will also be triggered if the goods are in storage for too long. For example, by setting a scheduled task to continuously scan the data in the system, if the length of time each item has been in the warehouse exceeds 30 days, 60 days, or 90 days, the administrator will be reminded to handle it.

[0039] In some embodiments, the digital twin interface will also display the raw material warehouse management module vegetable dog warehouse receipt page, raw material delivery page, real-time inventory page, inventory inventory interface, among which the purchase warehouse receipt page It mainly includes the business of raw materials entering the warehouse. The warehouse entry form entered by the user on the mobile terminal will be displayed here, and the administrator can approve or reject it on this interface. If approved, the data will be added to the real-time inventory interface. If rejected, the document will be invalidated. The raw material outbound form mainly includes the business of raw materials leaving the warehouse. The outbound form entered by the user on the mobile terminal will be displayed on the digital twin interface, and the administrator can approve or reject it on this interface. If approved, the data will be deleted from the real-time inventory interface. If rejected, the document will be invalidated. Real-time inventory, the real-time goods data of all warehouses currently existing in real time cannot be directly operated and can only be viewed. The data will change after operating on the warehouse entry and outbound interfaces.

[0040] In some embodiments, the digital twin interface will also display the finished product warehouse management module's finished product receipt page, finished product delivery page, real-time inventory page, and inventory counting interface. Among them, the finished product receipt mainly includes the business of finished product goods entering the warehouse. The receipt entered by the user on the mobile terminal will be displayed on the digital twin interface, and the administrator can then pass or reject it on this interface. If passed, the data will be appended to the real-time inventory interface. If rejected, the document will be invalidated. The raw material delivery mainly includes the business of finished product goods leaving the warehouse. The delivery entry entered by the user on the mobile terminal will display the digital twin interface, and the administrator can then pass or reject it on this interface. If passed, the data will be deleted from the real-time inventory interface. If rejected, the document will be invalidated. The real-time inventory shows the real-time goods data of all finished product warehouses that currently exist in real time. It cannot be directly operated but can only be viewed. The data will change after operations on the receipt and delivery interfaces.

[0041] In some embodiments, the digital twin interface will also display the auxiliary material warehouse management module purchase warehouse order page, auxiliary material outbound order page, real-time inventory page, and inventory counting interface, among which the auxiliary material warehouse order page It mainly includes the business of auxiliary materials entering the warehouse. The digital twin interface will be displayed for the entry form entered by the user on the mobile terminal. The administrator can then approve or reject it on this interface. If approved, the data will be added to the real-time inventory interface. If rejected, the document will be invalidated. The auxiliary materials outbound form mainly includes the business of auxiliary materials leaving the warehouse. The digital twin interface will be displayed for the entry form entered by the user on the mobile terminal. The administrator can then approve or reject it on this interface. If approved, the data will be deleted from the real-time inventory interface. If rejected, the document will be invalidated. The real-time inventory shows the real-time goods data of all auxiliary materials warehouses. It cannot be directly operated but can only be viewed. The data will change after operations on the entry and outbound interfaces.

[0042] In some embodiments, the digital twin interface will also display the system management module tenant management page, tenant management interface, application management interface, user management interface, menu management interface, and data dictionary. Among them, the tenant management interface supports multi-tenancy, and data is isolated between tenants. Each customer is a tenant. Each new customer adds a tenant and then configures the information. The customer's data is invisible to other customers. The implementation principle is to add a tenant id to each data, and each data operation must be distinguished by the id. The user management interface adds, deletes, resets passwords, and binds roles to users. The menu management edits menus, such as the front-end component address, menu name, and display order. The role management authorizes which menus the role can see. The data dictionary configures some common dictionary parameters, such as drop-down box options, switch parameters, etc.

[0043] In some embodiments, the warehouse management system also includes a role management module, which is configured to store a user and role (user-role) relationship table and a role and menu (manu-role) relationship table. When authorizing, the role is first authorized, that is, the data in the manu-role table is modified to determine which menus the user can view. For example, the administrator role can see all menus, and the warehouse manager role can only view the warehouse menu. Then the user is authorized, that is, the data in the user-role table is modified to determine whether the user is an administrator, a warehouse manager or a worker.

[0044] In some implementations, the warehouse management system uses the Vue framework on the front end and the Springboot technology on the back end. The data includes redis and mysql. The entire system architecture belongs to the B / S architecture. Users operate the front-end pages, and the back-end services process requests and modify the database data. Redis is mainly used to store tokens to ensure the security of the system.

[0045] In some implementations, the homepage of the warehouse management system will display the warehouse data of the entire factory in the form of charts, including the goods in stock, the goods shipped in and out of stock in the past month, safety inventory warnings, etc. Through the digital twin interface on the computer, the warehouse of the entire factory is drawn on the interface by modeling, and all data flows in real time, including warehouse capacity, storage location capacity, number of steel coils, etc. In some embodiments, the operation flow of the user operating the computer-side digital twin interface is shown in Figure 3As shown, the first-line warehouse manager fills in the data-generated warehouse entry form on the mobile terminal, and it will finally be displayed on the warehouse entry form interface on the computer terminal. The second-line warehouse manager can review and complete the warehouse entry here; the first-line warehouse manager fills in the goods information on the new warehouse entry interface on the mobile terminal, uploads the attachments, and then prints out the label with the QR code and pastes it on the goods. Click to pass directly to enter the goods directly. The first-line warehouse manager scans the code on the mobile terminal to produce the outbound order, which will finally be displayed on the outbound order interface on the computer terminal. The second-line warehouse manager can review and complete the outbound here; the first-line warehouse manager only needs to click the button to scan the material on the outbound order interface on the mobile terminal, and then scan the QR code label on the steel coil to directly complete the outbound. The second-line warehouse manager adds an inventory counting task on the inventory counting interface on the computer terminal, sets the inventory start time, end time, inventory personnel, etc. After receiving the inventory counting task, the first-line warehouse manager first scans the warehouse QR code and then scans the QR code on the goods to count the goods. The whole process of scanning the code is completed without filling in any data. The scanning results of each product are divided into three types: no gain or loss: that is, the actual number of goods is consistent with the number of system data locations; overflow: there is no goods at this location in the system, but there are actually goods; loss: there is goods at this location in the system, but there are actually no goods. After the inventory count is completed, the warehouse managers will know the situation of each product. At this time, the system will remind the warehouse managers to perform subsequent operations to correct the data. For example, goods with overflow need to be put into the warehouse, and goods with loss need to be taken out of the warehouse, so that the system data is consistent with the actual situation.
