Description

Technical Field

[0001] The invention belongs to the technical field of steel plate finished product warehouse management, and specifically relates to a method for information management of a steel finished product warehouse. Background Art

[0002] In the management of finished steel plate warehouses, the current stacking positions for steel plates are manually designated, which has low efficiency and cannot fully consider the efficiency of reverse transportation. Without intermediate inventory stacking position management, the specific stacking positions of steel plates cannot be accurately tracked in the finished product storage area, and a large amount of manpower is required to find and record the location of steel plates, which affects production and delivery efficiency. The inventory, stacking, loading and shipping, etc., mainly rely on manual recording on-site through identification, transcription, and photography of steel plate side spraying, and then returning to the operation room to reconfirm the information with the MES interactive system and perform related operations in the MES interactive system. At the same time, the photos are archived. If there are any abnormalities during the period, they need to return to the site for multiple confirmations. During the inventory, the inventory personnel print out the details of the steel plates at each stacking position in the finished product warehouse, and then go to the finished product warehouse to count and check them one by one. After returning to the office, the stacking positions are adjusted if the information and the actual objects are inconsistent. The traditional method requires manual on-site photography and transcription of steel plate side spraying, which has low accuracy and consumes a lot of manpower. At the same time, frequent on-site operations also increase the safety risks of employees. Summary of the invention

[0003] The purpose of the present invention is to provide a method for information management of a steel product warehouse.

[0004] The technical solution adopted by the present invention to solve the technical problem is: a method for information management of steel finished product warehouse, comprising the following steps:

[0005] 1) Establish a local wireless network in the finished product warehouse and delivery parking lot, and connect it to the terminal collection system to achieve real-time communication between handheld terminals, fixed terminals and MES interactive system;

[0006] 2) Warehousing stage: The steel plate coding automatic identification system is used to realize the warehousing identification. A rail-type side spray identification camera is added at the warehousing roller position to identify the steel plate side spray information, synchronize it to the operating console and MES interactive system, and automatically compare it with the MES information to realize the accuracy verification of the steel plate side spray information;

[0007] 3) Intermediate warehouse stage: After the steel plate information is entered into the MES interactive system, the system will combine the steel plate customer, size attribute information, warehousing, loading, and stacking rules and requirements to build an MES interactive system to automatically recommend a preset stacking algorithm. If the warehouse number and stacking number are used as query conditions, all steel plates with the warehouse number and stacking number will be queried from the inventory;

[0008] 4) Inventory stage: By using handheld terminal collection equipment, the on-site steel plate information interacts with the MES interactive system to verify the accuracy of on-site information and conduct on-site inventory;

[0009] 5) Outbound stage: By combining handheld terminal data collection equipment with the electronic display of loading site information, automatic confirmation of loading and shipping site information can be achieved, and shipping photos can be automatically retained.

[0010] Specifically, the steel plate coding automatic recognition system adopts OCR recognition technology, calls C++ on the Android side, passes the image obtained by the camera to the C++ bottom layer for detection, determines the text position, crops the image, recognizes the model, and returns the detection and recognition results.

[0011] Specifically, the on-site inventory of steel plates in step 4) is to obtain a saved list of all steel plate data on the warehouse number and stack number from the warehouse management system according to the warehouse number and stack number. When recognizing the real-time image or album picture, the recognition result is compared with the list data. If the steel plate number is in the list, it is in the steel plate confirmed status. If it is not in the list, it is in the steel plate added status. At the end of the scan, the newly added steel plates and the steel plate numbers that have not been scanned are specially marked.

[0012] Specifically, the electronic loading site information is to use a rail-type movable steel plate side spray camera robot at the shipping site to automatically identify the loading information, confirm the information, and automatically retain the loading photos.

[0013] Specifically, the step 5) delivery confirmation is to obtain all the steel plate data for this shipment and save them as a list. When identifying the real-time picture or album picture, each recognition result list data is compared. If the steel plate number is in the list, it is in the steel plate confirmation state. If it is not in the list, it is in the steel plate abnormal state. The steel plate number in the abnormal state is not allowed to be shipped out or uploaded.

[0014] The present invention has the following beneficial effects:

[0015] 1) Through the implementation of the finished product warehouse information construction project, the physical inventory and system data can be updated synchronously, which can improve the efficiency of inventory counting and loading and shipping, thereby greatly improving the utilization and management efficiency of the warehouse area; it can give play to the latecomer advantage: reduce labeling errors and quality objections, reduce the labor intensity of workers, reduce the probability of safety accidents among employees, reduce personnel allocation, reduce equipment failure rate, improve operating efficiency, extend the service life of vehicles, reduce production and operation costs, further improve the level of intelligent production lines, and improve market competitiveness;

[0016] 2) Reduce quality objection losses and cargo preservation losses: Based on the informationization improvement of side-spray identification, the function of information and physical object comparison with the MES interactive system is added during the whole process of side-spray identification, which can effectively avoid quality objection losses and cargo preservation losses caused by printing errors or loading errors;

[0017] 3) Improve the level of information management: Recommending stacking positions based on product quality, inventory management, and shipping management needs can effectively improve warehouse storage and shipping efficiency, shorten the time to find boards, reduce inventory turnover, improve the operating rate of driving equipment, and reduce customer waiting time. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a side spray recognition and training model. DETAILED DESCRIPTION

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] A method for information management of steel finished product warehouses, which adopts a coding automatic recognition system, a terminal collection system (including handheld and fixed types), and an MES interactive system, and organically combines them to greatly improve the accuracy of information transmission and information management in the warehousing and outbound links, improve production and delivery efficiency, and reduce labor intensity.

[0021] The information management system of steel finished product warehouse mainly includes finished product entry and exit functions, intermediate warehouse and stacking management functions, and inventory management functions. The management functions cover the entire process of finished product warehouse logistics information, and data interfaces can be reserved to expand data management functions.

[0022] A method for information management of a steel product warehouse comprises the following steps:

[0023] 1. Establish a local wireless network in the finished product warehouse and delivery parking lot, and connect it to the terminal collection system to achieve real-time communication between handheld terminals, fixed terminals and MES interactive system.

[0024] 2. Warehouse entry stage: A rail-type side spray identification camera is added at the warehouse entry roller to identify the side spray information of the steel plate, synchronize it to the operating console and MES interactive system, and automatically compare it with the MES information to verify the accuracy of the side spray information of the steel plate. The steel plate code automatic identification system is used to realize warehouse entry identification, and the warehouse information is checked at the source to reduce the risk of steel plate identification errors.

[0025] 3. Warehousing stage: The OCR recognition technology used in the automatic identification system for steel plate coding calls C++ on the Android side, passes the image obtained by the camera to the C++ bottom layer for detection, determines the text position, crops the image, identifies the side spray recognition and the training model recognition, and returns the detection and recognition results. Using C++ combined with artificial intelligence reasoning can greatly improve the reasoning speed, and after screening, the recognition results are sent to the background system (generally referring to the MES interactive system) for effective management. After OCR recognition and artificial intelligence algorithms, combined with the side spray rule setting, the recognition accuracy is increased to more than 99.9%.

[0026] 4. Warehousing stage: Figure 1 As shown, the text recognition process of side spray recognition and training model based on deep learning needs to go through three steps: "data preparation", "data labeling" and "data evolution".

[0027] 5. The automatic identification technology of steel plate coding can mainly achieve the following goals: identify the side-sprayed information of steel plates, automatically compare it with the MES information, and verify the accuracy of the side-sprayed information of steel plates; automatically alarm for steel plates that do not meet the storage conditions or steel plates with incorrect markings.

[0028] 6. The administrator of the steel plate coding automatic identification system enters the warehouse operator information into the handheld terminal system. When logging in to the handheld terminal, the information of the logged-in personnel must be verified with the information entered in the system. The information can be modified and corrected by manual input of information or side spray identification.

[0029] 7. Intermediate warehouse stage: After the steel plate information is entered into the MES system, the system will combine the steel plate customer, size and other attribute information, warehousing, loading, stacking and other rules and requirements to build a system to automatically recommend preset stacking positions. The algorithm automatically recommends preset stacking positions and realizes intelligent stacking position recommendation, thereby reducing the operation of stacking and overhead crane operation and improving warehousing and shipping efficiency.

[0030] 8. Intermediate warehouse stage: Using warehouse number and stack number as the query condition, you can query all steel plates with the warehouse number and stack number from the inventory. Using steel plate number as the query condition, you can query the warehouse number and stack number where the steel plate number is located and all steel plate numbers on the warehouse number and stack number from the inventory.

[0031] 9. Inventory stage: By using handheld terminal collection equipment, the on-site steel plate information interacts with MES, realizing on-site information accuracy verification, on-site inventory reverse stamping and other functions, reducing the manual on-site inventory transcription and returning to the operation room to confirm the information and improve inventory efficiency.

[0032] 10. The steps to implement on-site inventory and on-site stack adjustment of steel plates are as follows: first, obtain a saved list of all steel plate data on the warehouse number and stack number from the warehouse management system according to the warehouse number and stack number. When identifying the real-time image or album picture, compare the identification result with the list data. If the steel plate number is in the list, it is in the steel plate confirmation status. If it is not in the list, it is in the steel plate added status. At the end of the scan, the newly added steel plates and the steel plate numbers that have not been scanned will be specially marked.

[0033] 11. Outbound stage: By combining handheld terminal collection equipment with electronic display of loading site information, automatic confirmation of loading and shipping site information and automatic retention of shipping photos are achieved. This reduces the original steps of manual printing of documents, manual identification of information, and photo retention during loading confirmation and shipping, and simplifies the operation process.

[0034] 12. Outbound stage: At the shipping site, a rail-mounted movable steel plate side spray camera robot is used to automatically identify loading information, confirm the information, automatically retain loading photos, and conduct final checks on the steel plate information before leaving the factory.

[0035] 13. The delivery confirmation link is implemented as follows: first, obtain all the steel plate data for this shipment and save them as a list. When identifying the real-time picture or album picture, compare the data in each recognition result list. If the steel plate number is in the list, it is in the steel plate confirmation state. If it is not in the list, it is in the steel plate abnormal state. The steel plate number in the abnormal state is not allowed to be shipped out or uploaded.

[0036] 14. The system of the present invention configures software isolation and hardware isolation on the data network; multi-level security control, and reasonable configuration of functional permissions. Improve the operational safety and data security of the system. The system application framework adopts modular design and provides a system management module to support system maintenance work. Ensure the future expansion needs of the system.
