Description

Technical Field

[0001] The present invention relates to the technical field of production management of industrial blockchains, and in particular to a production management system, method and computer equipment based on SMT. Background Art

[0002] In traditional SMT production management, information is often scattered in various departments or systems, such as the production department, quality inspection department, warehouse management department, etc. There are obstacles to information sharing between these departments, resulting in low overall information transparency. For example, the production department may not be able to obtain accurate information on the material inventory of the warehouse in a timely manner, affecting the adjustment of the production plan. For external partners, such as suppliers and customers, it is even more difficult to obtain detailed information in the production process, which is not conducive to the collaborative management of the supply chain. In addition, most production management data is stored in a centralized database, which poses a risk of data being tampered with. Whether it is for improper purposes by internal employees or the database is attacked by external attacks, once the data is tampered with, it will seriously mislead production management decisions. For example, in terms of quality inspection data, if it is tampered with, it may cause unqualified products to flow into the market.

[0003] In addition, under the traditional method, the information records of material flow, equipment use, process parameters, etc. in the production process are incomplete or not strongly correlated. When there is a problem with the product, it is difficult to accurately trace the link where the problem occurred. It is difficult to judge whether it is a problem with the material itself, a failure of the production equipment, or an error in the process execution. For example, when a batch of products is found to have welding quality problems, due to the lack of a complete traceability system, it is difficult to determine whether it is due to improper welding equipment parameter settings, problems with the solder materials used, or operator errors. There is a lack of effective means to monitor the production progress in real time, and the adjustment of production plans often lags behind the actual production situation. For example, when encountering sudden equipment failures or delayed material supply, the production plan cannot be adjusted in time, resulting in production delays and affecting the order delivery time. For potential risks in the production process, such as the imminent shortage of inventory materials and the equipment reaching the maintenance cycle, the traditional method cannot issue early warnings in time. This may lead to production interruptions and increase production costs. For example, the production line is shut down due to material shortages, resulting in idle waste of manpower and equipment.

[0004] Along with this, traditional quality inspections are mostly post-inspections, that is, inspections are carried out at specific stages of the production process or after the product is produced. This method makes it difficult to detect quality problems in a timely manner and correct them during the production process, resulting in a large amount of resources being wasted on the production of unqualified products. For example, when the final product is found to be unqualified, the materials, manpower, and equipment time previously invested in the product are wasted. Due to the lack of a comprehensive data recording and traceability system, when quality problems arise, it is difficult to accurately find the root cause of the problem. This makes it impossible to take fundamental measures to solve quality problems, resulting in repeated quality problems and affecting the overall quality level of the product. The production management based on SMT on the industrial blockchain lacks full-dimensional and full-production line cycle supervision and maintenance, resulting in low production efficiency and increased production costs. Summary of the invention

[0005] Based on this, it is necessary to provide an SMT-based production management system, method and computer equipment that can efficiently coordinate the full-cycle management efficiency of production on the industrial blockchain to address the above technical problems.

[0006] A production management system based on SMT, the system comprising: an identification management platform, an SMT industry production application module, an industrial data storage module based on blockchain, and a contract development module; wherein the SMT industry production application module comprises: a supplier management module, a material management module, a product management module, and a quality inspection management module.

[0007] The identification management platform is used to parse the external management standard nodes and generate a standard identification data structure. According to the standard identification data structure, identification information is allocated to the supplier management module, material management module, product management module and quality inspection management module respectively, and the allocated identification information is recorded in the industrial data storage module, and a local identification database is established.

[0008] The industrial data storage module is used to deploy smart contracts on the system and call the smart contracts of the SMT industry production application module to store the assigned identification information records.

[0009] The contract development module is used to generate an intelligent development contract according to a preset contract mechanism, and deploy the intelligent contract on the industrial data storage module according to the intelligent development contract.

[0010] A production management method based on SMT, the method comprising:

[0011] After the data information of each management link in the SMT industry production application is marked and labeled through the identification management platform, the management links are associated with the data information based on the order information of the production process, and the associated data information is stored in the identification management platform, and the corresponding smart contract of the management link is triggered to record the associated data information on the blockchain-based industrial data storage platform.

[0012] The identification management platform completes the production process management based on the associated data information and the smart contract of the blockchain-based industrial data storage platform.

[0013] A computer device comprises a memory and a processor, wherein the memory stores a computer program, and when the processor executes the computer program, the following steps are implemented:

[0014] After the data information of each management link in the SMT industry production application is marked and labeled through the identification management platform, the management links are associated with the data information based on the order information of the production process, and the associated data information is stored in the identification management platform, and the corresponding smart contract of the management link is triggered to record the associated data information on the blockchain-based industrial data storage platform.

[0015] The identification management platform completes the production process management based on the associated data information and the smart contract of the blockchain-based industrial data storage platform.

[0016] In the above-mentioned production management system, method and computer equipment based on SMT, firstly, the design of the identification management platform greatly enhances the transparency of the production process. By parsing the external management standard node to generate the standard identification data structure, the system can clearly assign identifications to various links such as suppliers, materials, products and quality inspection. This structured identification information not only facilitates the collaborative operation between modules, but also forms a clear production process chain, which is convenient for managers to monitor various indicators in real time and improve transparency. Secondly, the introduction of blockchain technology makes data storage and management safer and more reliable. The industrial data storage module records the identification information through smart contracts to ensure that the data cannot be tampered with during the storage process. Any modification to the data will be automatically recorded to ensure the authenticity and integrity of the data. This mechanism solves the problem of easy data tampering in traditional production management and makes information records more credible. In terms of traceability difficulties, the system makes the records of each production link traceable by establishing a local identification database and recording the information on the blockchain. This efficient traceability mechanism allows managers to quickly locate the root cause of the problem in the production process, especially when quality problems occur, they can quickly find the relevant materials and suppliers through identification information, greatly shortening the time for problem handling and improving the response speed. In response to the problems of delayed plan adjustment and untimely early warning, the supplier management, material management and product management modules in the SMT industry production application module can provide real-time feedback on the production status, and timely adjustment suggestions can be made based on the real-time data analysis system. The contract development module can quickly generate and deploy smart contracts according to changes in market demand to adapt to the adjustment of production plans and improve production flexibility. In addition, the introduction of the quality inspection management module ensures that product quality can be effectively monitored at every stage. By combining with the identification management platform, the system can record quality inspection data in real time during the production process to form a complete quality traceability chain. This mechanism can not only control the quality of products before they leave the factory, but also adjust production standards in time in the later market feedback to optimize product quality. In summary, the production management system based on SMT realizes the full-cycle management of the production process through advanced technical means such as identification management, blockchain technology, and smart contracts, improves transparency, security and response speed, and significantly improves the efficiency and effectiveness of production management.

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] In one embodiment, Figure 1 As shown, a production management system based on SMT is provided, including: an identification management platform 102, an SMT industry production application module 104, an industrial data storage module 106 based on blockchain, and a contract development module 108; the SMT industry production application module 104 includes: a supplier management module 10402, a material management module 10404, a product management module 10406, and a quality inspection management module 10408; wherein:

[0023] The identification management platform 102 is used to parse the external management standard node and generate a standard identification data structure. According to the standard identification data structure, identification information is allocated with the supplier management module 10402, the material management module 10404, the product management module 10406 ​​and the quality inspection management module 10408 respectively, and the allocated identification information is recorded in the industrial data storage module 106, and a local identification database is established.

[0024] The industrial data storage module 106 is used to deploy smart contracts on the system and call the smart contracts of the SMT industry production application module to store the assigned identification information records.

[0025] The contract development module 108 is used to generate an intelligent development contract according to a preset contract mechanism, and deploy the intelligent contract on the industrial data storage module 106 according to the intelligent development contract.

[0026] In one embodiment, the externally managed standard nodes include: enterprise nodes, electronic industry secondary nodes and top nodes. The identification management platform is also used to generate coding rules and formats of standard identifications according to the enterprise nodes, electronic industry secondary nodes and top nodes.

[0027] In one of the embodiments, the supplier management module is used to identify and register material supplier information according to a standard identification data structure, and to establish information associations with the material management module, the product management module, and the quality inspection management module through a data sharing mechanism, and to store the labeled associated information in an industrial data storage module based on blockchain by calling a smart contract.

[0028] It is worth noting that supplier management assigns a unique ID to each material supplier and records the supplier's basic information, credit rating, supply history, etc. on the blockchain. This makes it easier for companies to manage and evaluate suppliers and select reliable suppliers. Establish a data sharing mechanism with suppliers to ensure that suppliers can upload material information to the blockchain in a timely manner. For example, suppliers can write information such as the batch number, quantity, and production date of materials into the blockchain when shipping, and companies can query this information in real time to prepare for receiving materials.

[0029] In one embodiment, the material management module is used to read the marked material supplier information when the material arrives at the enterprise warehouse, parse the identification information according to the standard identification data structure, and call the smart contract to verify the marked associated information written in the blockchain-based industrial data storage module. If the verification is valid, the material entry contract is triggered, and the contract records the marked material supplier information on the blockchain-based industrial data storage module and updates the inventory status of the enterprise warehouse. Otherwise, the contract triggers the return process and sends a return processing notification to the supplier management module so that the supplier management module executes the problem material processing mechanism.

[0030] It is worth noting that when the materials arrive at the enterprise warehouse, the staff uses a scanning device to read the identification on the materials. The identification information is identified through the identification management system and verified with the blockchain. If the identification information is valid, the system will trigger the material entry contract. The contract will automatically record the material information on the blockchain, including the material name, specification, batch number, quantity, entry time, etc., and update the inventory status. At the same time, the system can conduct quality spot checks on the materials according to the preset rules. If the spot check is qualified, the materials can be put into storage normally; if it is unqualified, the contract will automatically trigger the return process and notify the supplier to handle it.

[0031] In one of the embodiments, a product management module is used to formulate a production plan based on customer orders and factory production capacity, record the production plan in a blockchain-based industrial data storage module by calling a smart contract, and mark the production equipment and production data according to a standard identification data structure to generate production marking information, so that the smart contract can monitor the production progress through the production marking information and obtain production progress information. When the production progress information is less than a preset standard production cycle, the smart contract generates an early warning notification, and the product management module adjusts the production plan according to the early warning notification, and updates the production marking information of the adjusted production plan on the blockchain-based industrial data storage module and identification management platform through the smart contract.

[0032] It is worth noting that the production planning department formulates a detailed production plan based on customer orders and production capacity, and records the production plan information on the blockchain. The production plan should include product models, quantities, production schedules, etc. The smart contract will automatically monitor the production progress and update the production progress information in real time by reading the identification on the production equipment or the production data entered manually. If there is a delay in the production progress, the contract will issue an early warning notification to remind relevant personnel to take measures. When the production plan needs to be adjusted, the production planning department can modify the production plan information in the system, and the contract will automatically update the relevant data and notify the relevant departments and personnel.

[0033] In one embodiment, the quality inspection management module is used to set quality inspection points at each link of SMT production. The inspection equipment inspects the product according to the quality inspection points and the production annotation information, generates the inspection results, and uploads the inspection results to the industrial data storage module based on the blockchain, so that the smart contract can judge the quality inspection information of the product according to the preset quality standards. If the quality inspection information is unqualified, the smart contract triggers the rework process, notifies the product management and related producers to handle the unqualified products, and updates the identification information corresponding to the production annotation information in the industrial data storage module based on the blockchain according to the quality inspection information. Otherwise, the product annotation information is generated, the product annotation information is identified by the identification management platform, and the product annotation information is verified according to the production annotation information of the industrial data storage module based on the blockchain. If the verification result is valid, the product warehousing smart contract is triggered, and the inventory status is updated according to the product warehousing smart contract. Otherwise, the smart contract triggers the rework process, notifies the product management and related producers to handle the unqualified products, and updates the identification information corresponding to the production annotation information in the industrial data storage module based on the blockchain according to the quality inspection information.

[0034] It is worth noting that in each link of SMT production, quality inspection points are set up, such as patch quality inspection, welding quality inspection, etc., equipped with corresponding inspection equipment and personnel. The inspection equipment can read the logo on the product and automatically upload the inspection results to the blockchain. The quality inspection contract will automatically determine whether the product is qualified according to the preset quality standards. If the product is unqualified, the contract will automatically trigger the rework process and notify the relevant personnel to handle it. At the same time, the information of unqualified products will be recorded on the blockchain for subsequent tracing and analysis of the root cause of quality problems. The source of the problem can also be analyzed for the products with problems: the supplier, raw materials, process flow and other information associated with the problem product can be queried through the logo, and the information and analysis results can be fed back to the blockchain network. Each node authenticates the analysis results to ensure the reliability of the analysis. For key quality parameters, such as the reflow soldering temperature curve, a real-time monitoring mechanism can be set up. Once an abnormality is found, an early warning notification will be issued immediately to avoid the expansion of quality problems.

[0035] When the product is produced, the staff uses a scanning device to read the logo on the product. The logo management system automatically identifies the logo information, associates and queries the detailed information of the product, and verifies it with the blockchain. If the logo information is valid, the application system triggers the product entry contract. The contract automatically records the product information on the blockchain, including product model, quantity, production date, quality inspection results, etc., and updates the inventory status. After the product is entered into the warehouse, reasonable inventory management and scheduling can be carried out according to customer orders and inventory conditions.

[0036] In one of the embodiments, the product management module is also used to parse the product identification information through the identification management platform when the product is shipped out, and call the smart contract and the production marking information of the blockchain-based industrial data storage module for verification. If the verification result is valid, the product shipping smart contract is triggered, and the production marking information corresponding to the product identification information on the blockchain-based industrial data storage module is deleted according to the product shipping smart contract, and the inventory status is updated, and the shipping order and logistics information are generated.

[0037] It is worth noting that when a product needs to be shipped out of the warehouse, the staff uses a scanning device to read the logo on the product. The logo information is automatically identified by the logo management system and verified with the blockchain. If the logo information is valid, the application system triggers the product shipment contract. The contract automatically deletes the product information from the blockchain and updates the inventory status. At the same time, the contract generates a shipment order and logistics information to facilitate the transportation and tracking of the product. For important customers or high-value products, additional verification mechanisms such as digital signatures or encrypted verification can be set to ensure the safe delivery of the product.

[0038] In one embodiment, if Figure 2 As shown in the figure, an SMT production management system based on identity resolution and blockchain smart contract is provided. The SMT identity management system is used to generate, register, query and update identities, and connect enterprise nodes, secondary nodes of the electronics industry, and national top nodes. The system should have a user-friendly interface to facilitate the operation of enterprise employees. Determine the coding rules and formats of the identity to ensure the uniqueness and readability of the identity. The identity contains necessary information, such as item name, specification, batch number, production date, etc. Establish an identity database to store the relevant information of the identity and synchronize it with the blockchain. In this way, the identity information can be quickly queried locally while ensuring the consistency and reliability of the data. Integrate the identity resolution technology with the blockchain platform to achieve seamless connection between the identity and blockchain data. Develop corresponding interfaces and middleware to ensure that the identity information can be accurately written into the blockchain, and that the identity-related data can be read and verified from the blockchain.

[0039] Design corresponding smart contracts according to each link of SMT production management, including material procurement, production planning, quality inspection, product warehousing, etc. Clarify the rules, conditions and trigger mechanisms of the contract to ensure that the contract can accurately reflect the business logic of production management. Use smart contract development language to write contract code, and conduct strict testing and auditing to ensure the security and correctness of the contract. Build a blockchain-based industrial data storage system and deploy smart contracts to the system so that it can be automatically executed during the production process.

[0040] Each module in the above-mentioned SMT-based production management system can be implemented in whole or in part by software, hardware, or a combination thereof. Each of the above-mentioned modules can be embedded in or independent of a processor in a computer device in the form of hardware, or can be stored in a memory in a computer device in the form of software, so that the processor can call and execute operations corresponding to each of the above modules.

[0041] In one embodiment, Figure 3 As shown, a production management method based on SMT is provided, which is applied to Figure 1 The system in is taken as an example to illustrate, including the following steps:

[0042] Step 302: After the data information of each management link in the SMT industry production application is marked and labeled through the identification management platform, the management links are associated with the data information according to the order information of the production process, and the associated data information is stored in the identification management platform, and the smart contract corresponding to the management link is triggered to record the associated data information on the blockchain-based industrial data storage platform.

[0043] Specifically, an identification management platform is established to generate and manage identification. The platform connects to the national top-level node of identification resolution and the secondary node of the electronics industry, supports the registration, query, update and other operations of identification, and ensures the accuracy and effectiveness of identification. The platform uses identification resolution technology to generate unique identification for materials, equipment, products, etc. in each SMT production link. The identification contains rich information, such as item name, specification, batch number, production date, manufacturer, etc. The identification is attached to the corresponding item in the form of electronic tags, QR codes, etc., so that it can be identified and tracked during the production process.

[0044] Furthermore, we build SMT industry applications to control the SMT production process. Specifically, we include:

[0045] 1. Supplier Management

[0046] Assign a unique ID to each material supplier and record the supplier's information on the blockchain. This makes it easier for companies to manage and evaluate suppliers and select reliable suppliers. Establish a data sharing mechanism with suppliers to ensure that suppliers can upload material information to the blockchain in a timely manner.

[0047] 2. Material Management

[0048] During the material procurement stage, the source, specifications, batch number and other information of the material are recorded through identification, and this information is uploaded to the blockchain. When the material enters the warehouse, the identification is scanned, the material entry contract is called, the material information is recorded on the blockchain, and the inventory status is updated. During the production process, the use of materials is tracked through identification to ensure the correct use and traceability of materials.

[0049] 3. Production planning management

[0050] According to customer orders and production capacity, a production plan is formulated and the production plan information is recorded on the blockchain. The production plan contract monitors the production progress and issues early warning notifications in a timely manner when the production progress is delayed. When the production plan is adjusted, the relevant information is automatically updated through the blockchain smart contract to ensure the accuracy and timeliness of the production plan.

[0051] 4. Quality inspection management

[0052] During the production process, quality inspection is carried out on each production link, and the inspection results are recorded on the blockchain. The quality inspection contract will determine whether the product is qualified according to the preset quality standards. If the product is unqualified, the rework or scrapping process will be automatically triggered. Through the traceability of the blockchain, the root cause of quality problems can be quickly located, improving the efficiency of solving quality problems.

[0053] 5. Product Management

[0054] When the product is produced, the product information is recorded through the mark and uploaded to the blockchain. The product entry contract is called to record the product information on the blockchain and update the inventory status. When the product is shipped out, the mark is scanned, the product shipment contract is called, the product information is deleted from the blockchain, and the inventory status is updated.

[0055] Step 304, the identification management platform completes the production process management according to the associated data information and the smart contract of the blockchain-based industrial data storage platform.

[0056] According to the needs of SMT production management, a series of blockchain smart contracts are designed. For example, material procurement contracts, production planning contracts, quality inspection contracts, product warehousing and outbound contracts, etc. Smart contracts contain clear rules and conditions. When these conditions are met, the contract will perform corresponding operations. For example, when the material arrives at the warehouse, the material warehousing contract is called to record the material information on the blockchain.

[0057] Specifically, we build an industrial data storage system based on blockchain, and deploy smart contracts on the system. The underlying system is based on blockchain technology, which ensures the security and reliability of the contract. According to the various links of SMT production management, such as material procurement, production planning, quality inspection, product warehousing, etc., we design corresponding smart contracts. We clarify the rules, conditions and trigger mechanisms of the contract to ensure that the contract can accurately reflect the business logic of production management. We use the smart contract development language to write the contract code, and conduct strict testing and auditing to ensure the security and correctness of the contract. We build an industrial data storage system based on blockchain, and deploy smart contracts on the system so that they can be automatically executed during the production process.

[0058] In the above-mentioned SMT-based production management method, firstly, the introduction of the identification management platform solves the problem of low transparency of the production process. The information of each management link is identified and labeled to ensure that the relevant data is consistent and traceable in the system. By associating the data of each link with the order information, managers can monitor the production progress in real time, find potential problems and make timely adjustments, improve transparency, and enhance the control over the overall production. Secondly, the blockchain-based industrial data storage platform provides a guarantee for the safe storage of data information. All associated data information is recorded on the blockchain, and the data cannot be tampered with during the storage process through the triggering and execution of smart contracts. This feature effectively solves the problem of easy data tampering in traditional production management, so that all recorded data has a high degree of credibility and security, and avoids data distortion caused by human operation. In terms of traceability, the solution realizes efficient production process traceability through the combination of the identification management platform and blockchain data storage. Each data record is closely related to the production link. If quality problems occur in the later stage, managers can quickly trace back to the relevant materials and suppliers, clarify responsibilities and take remedial measures quickly. This traceability capability greatly reduces the time and cost of handling quality problems. For the problems of delayed plan adjustment and untimely early warning, the real-time data association of the identification management platform and the dynamic execution capability of smart contracts enable the production plan to be quickly adjusted according to market changes and production status. The system can analyze production data in real time and issue early warnings in time to ensure that managers can make timely decisions and enhance the flexibility and adaptability of production. In addition, the management of the quality inspection link can be effectively integrated with the identification management platform, so that the quality data of each product can be recorded and monitored in real time. The recording method based on blockchain technology ensures the authenticity and integrity of quality data, thereby improving the qualified rate of products, and can quickly adjust production standards in market feedback to ensure continuous improvement of product quality. In summary, through the combination of the identification management platform and blockchain-based industrial data storage, this technical solution effectively solves many problems in the production process, such as low transparency, easy data tampering, and difficult traceability. It not only improves the efficiency and effectiveness of production management, but also lays a solid foundation for the efficient coordination of the entire production cycle management on the industrial blockchain, and provides strong support for the sustainable development of enterprises.
