[0065] In one embodiment, if Figure 1 As shown, the first aspect of the present invention provides a product process configuration method for a LMES system, comprising:

[0066] S1. Configure a product process template; the product process template includes processing actions and operation logic for a specific business scenario;

[0067] S2. Monitor and obtain a process configuration signal of a product triggered by a controller; the process configuration signal includes a business scenario;

[0068] S3, calling the product process template according to the business scenario, so that the product performs a corresponding processing action;

[0069] S4. After the processing action is completed, a process completion signal is sent to the controller, so that the controller resets the process configuration signal and the product code according to the process completion signal.

[0070] Among them, the controller is also called a programmable logic controller PLC. This application provides a variety of product process templates, which are easy to call according to user needs, quickly build business scenarios that meet user needs, and use the processing actions and operation logic in the templates to process the products to adapt to different production needs and environmental changes; after the processing is completed, the scheme of who triggers and who resets is adopted to realize paired management of signals, which brings multiple benefits of clear division of responsibilities, simplified interaction logic, enhanced controllability, and improved safety and reliability.

[0072] S31, obtaining the product code of the product, and calling the product process template according to the business scenario; the product code is associated with the assembled material code and the scanned pallet code;

[0073] S32. mobilizing the target product according to the product code, so that the target product is processed according to the processing actions in the product process template.

[0074] Specifically, since the production of a product requires one or more processes on the production line, and the process is an indispensable productive force object (a combination of people, equipment, and tools) in the production execution process, and there are one or more products being processed on each production line, for the convenience of statistics, the products on the production line are numbered so that each product has its own product code, which is also associated with the material and pallet to facilitate the traceability of the product source.

[0075] When products are produced and processed, there are two control logics for product entry and exit: entry and exit separation, that is, the controller processes the entry signal and the exit signal independently, allowing them to trigger their corresponding control actions respectively without being affected by the other's state, so that one workstation can accommodate and process multiple products at the same time; entry and exit separation, the controller's exit signal triggering is constrained by the entry signal, that is, the workstation can only accommodate and process one product at a time, and a new product can only enter after the current product has completely left.

[0076] According to user needs, the target product can be processed by calling the template through the product code corresponding to the product, so that the LMES system can select the most suitable interaction method according to the actual situation to ensure the stable operation of the system and the achievement of production goals.

[0077] In one embodiment, the product process template at least includes an inbound business process template, and the inbound business process template includes an inbound initialization action, a processing type judgment action, and a multiple verification action under an inbound business scenario, and the operation logic corresponding to each action; wherein,

[0078] The operation logic corresponding to each action in the inbound business process template is as follows: Figure 3 As shown,

[0079] S111, after monitoring the station entry signal triggered by the controller, controlling the target product to enter the station, and initializing the station entry for the target product;

[0081] Specifically, the interaction process of the product entry business scenario is as follows:

[0082] 1. Interactive handshake upon entry: After the product arrives at the station, the PLC triggers the entry signal to inform the LMES system that the product has entered the station;

[0083] 2. Determination of product processing type: There are three types of processing, namely normal processing, rework processing and test product inspection processing;

[0084] 3. Types of verification for entering the station to prevent mistakes and errors: whether the product status is OK, whether the product is repeatedly entered for processing, whether the product is missing a processing step, third-party system entry verification, etc.

[0085] 4. Delivery of entry inspection results: The LMES system delivers the entry results, and the abnormal reasons are given to the register variable address of the PLC. The PLC takes the results to determine whether the product can be processed;

[0086] Other entry steps: Generate SN code for products upon entry, complete binding association between products and pallets, print product labels, etc.

[0087] In one embodiment, the product process template at least includes an outbound business process template, and the outbound business process template includes an outbound initialization action, an outbound parameter collection action, and an outbound qualified judgment action under an outbound business scenario, as well as the operation logic corresponding to each action; wherein,

[0088] The operation logic corresponding to each action in the outbound business process template is as follows: Figure 4 As shown,

[0089] S121, after monitoring the outbound signal triggered by the controller, performing outbound initialization on the target product;

[0090] S122, judging the processing result of the target product, and controlling the target product to exit the station according to the processing result; the processing result includes whether the target product is qualified;

[0091] S123, collecting quality parameters of outbound products, and generating outbound results and sending them to the controller; the outbound results include outbound results, processing results, quality parameters and reasons for product failure.

[0092] Specifically, the interaction process of the product outbound business scenario is as follows:

[0093] 1. Outbound interactive handshake: After the product is processed, the PLC triggers the outbound signal to inform the LMES system to make a product outbound judgment;

[0094] 2. Processing result judgment: There are three common methods, namely, the processing equipment judges the product status, the system judges the product status, and the third-party system judges the product status;

[0095] 3. Determination of defective causes: When a product is NG, there are two common ways to determine the defective cause, namely, the processing equipment determines the defective cause and the system determines the defective cause;

[0096] 4. Delivery of outbound results: The LMES system delivers outbound results, processing results and other information to the register variable address of the PLC, and the PLC takes the results to determine whether the product can be shipped;

[0097] Other outbound steps: cross-process parameter calculation, such as aging time determination of aging equipment, unbinding of outbound pallets and product binding, etc.

[0098] In one embodiment, the product process template at least includes a product processing business process template, and the product processing business process template includes a material assembly verification action, a material binding reporting action and a quality parameter update action under a product processing business scenario, and the operation logic corresponding to each action; wherein,

[0099] The operation logic corresponding to each action in the product processing business process template is as follows Figure 5 As shown,

[0100] S131, obtaining the assembled material code corresponding to the target product and performing material verification, obtaining the material verification result and uploading it to the controller; the material verification at least includes whether the material meets the material BOM requirements of the product model and whether the material length meets the requirements;

[0101] S132, processing the target product, obtaining a finished product and binding it with material information and uploading it to a third-party system;

[0102] S133: After monitoring the quality parameter update signal triggered by the controller, the quality parameters of the finished product are collected and stored, and the product status is determined and sent to the controller.

[0103] Specifically, the interactive process of the product processing business scenarios:

[0104] 1. Material assembly verification: Scan the material code, and the system will verify the material to determine whether the material meets the material BOM requirements of the product model, whether the material length meets the requirements, etc. The LMES system will feedback the results to the PLC;

[0105] 2. Material binding reporting: reporting the binding information of the assembly product and the material to the third-party system;

[0106] 3. Quality parameter update: After the PLC stores the quality parameters in the register, it triggers the quality parameter update signal, notifying the LMES system to collect and store the quality parameters and make product status judgments and send them to the PLC. Supplementary explanation: Since some processes support repeated processing or repeated testing of products, it is necessary to perform a cyclic interaction of the quality parameter update process. After each processing, the system is required to feedback to the manufacturing specialist what quality parameters of the current product are unqualified and guide the operator on how to repeat the processing.

[0107] Among them, the product processing and interaction diagram are as follows Figure 6 As shown, the product goes on the conveyor belt, and is processed from the first process OP10 according to the process route requirements, and is processed and finished at the last process OP90. If there is a production abnormality during the process, it will be discharged from the production line to the defective product storage area through the discharge port. Specifically, after the product goes on the conveyor belt, it is processed from the OP10 process until the last process OP90 is completed and it goes off the line. Each process station processing in the warehouse must initiate an entry application to the LMES system. The LMES system issues the entry result and the specific equipment processing process can only be carried out after it is OK; when the product is processed, whether the interactive process needs to be added depends on the production content of the process and the requirements of EU customers; after the product is processed at each process station, it is necessary to initiate an exit application to the LMES system. The LMES system collects quality parameters, judges the product status, and issues the exit result. When the product is OK, it continues to be processed in the next process. When it is NG, it is discharged to the nearest abnormal product discharge port.

[0108] In one embodiment, the product process template at least includes a label printing business process template, and the label printing business process template includes a barcode generation action and a label transcoding printing action in a label printing business scenario and the operation logic corresponding to each action; wherein,

[0109] The operation logic corresponding to each action in the label printing business process template is:

[0110] After the barcode generation signal is detected to be triggered, a product code is generated according to the barcode generation rules;

[0111] After the barcode printing signal is detected to be triggered, the product code is read and parsed, and the parsing result is converted according to the transcoding rule to obtain a label and print it.

[0112] In addition, product process templates may also include material assembly inspection business process templates, process formula distribution business process templates, binding update code business process templates, etc., which are not listed here one by one. This application provides a variety of predefined interactive process templates, so that for different production scenarios and PLC programming methods, users can select, modify or combine these templates according to actual needs, and quickly build interactive logic that meets specific scenarios. Users can implement different parameter configurations for different processes according to process requirements, configure different variable points and rules according to process functions, and complete fool-proof and error-proofing control, material assembly binding requirements, and third-party interaction requirements for each process station.

[0113] This application designs different functional modules for flexible combination and expansion. Through such modular design and integration, the flexibility, efficiency and quality control level of the production process can be significantly improved. It is also convenient for upgrading or adjusting each module in the future to adapt to different production needs and environmental changes to complete different operation processes, different fool-proofing measures and third-party interactions in different processes. The system supports dynamic loading of configuration fields for process-related process templates, realizes the compatibility of process management with different process templates, and reduces the front-end R&D costs.

[0114] In the embodiment of the present application, based on the fact that the existing interactive logic orchestration technology between the controller and the host computer generally has the problems of poor interoperability, high system complexity, difficulty in meeting customization requirements, insufficient security and reliability, and limited performance and scalability, a product process configuration method for the LMES system is designed, which realizes the configuration of product process templates; the product process template includes processing actions and their operation logic for specific business scenarios; monitors and obtains the process configuration signal of the product triggered by the controller; the process configuration signal includes business scenarios; calls the product process template according to the business scenario to enable the product to perform corresponding processing actions; after the processing action is completed, sends a process completion signal to the controller so that the controller resets the process configuration signal and the product code according to the process completion signal. The technical solution; adopts the interactive process scheme of who triggers and who resets, and realizes paired management of signals by agreeing on the responsibility for signal triggering and resetting, which brings multiple benefits such as clear division of responsibilities, simplified interactive logic, enhanced controllability, and improved security and reliability.

[0115] It should be noted that although the steps in the above flowchart are shown in sequence according to the arrows, these steps are not necessarily executed in the order indicated by the arrows.

This application provides a variety of product process templates, which are easy to call according to user needs, quickly build business scenarios that meet user needs, and use the processing actions and operation logic in the templates to process the products to adapt to different production needs and environmental changes; after the processing is completed, the scheme of who triggers and who resets is adopted to realize paired management of signals, which brings multiple benefits of clear division of responsibilities, simplified interaction logic, enhanced controllability, and improved safety and reliability.

[0141] Determine the processing result of the target product, and control the target product to exit the station according to the processing result; the processing result includes whether the target product is qualified;

[0142] The quality parameters of the outbound products are collected, and outbound results are generated and sent to the controller; the outbound results include outbound results, processing results, quality parameters and reasons for product failure.

[0143] Specifically, the interaction process of the product outbound business scenario is as follows:

[0144] 1. Outbound interactive handshake: After the product is processed, the PLC triggers the outbound signal to inform the LMES system to make a product outbound judgment;

[0145] 2. Processing result judgment: There are three common methods, namely, the processing equipment judges the product status, the system judges the product status, and the third-party system judges the product status;

[0146] 3. Determination of defective causes: When a product is NG, there are two common ways to determine the defective cause, namely, the processing equipment determines the defective cause and the system determines the defective cause;

[0147] 4. Delivery of outbound results: The LMES system delivers outbound results, processing results and other information to the register variable address of the PLC, and the PLC takes the results to determine whether the product can be shipped;

[0148] Other outbound steps: cross-process parameter calculation, such as aging time determination of aging equipment, unbinding of outbound pallets and product binding, etc.

[0149] In one embodiment, the product process template at least includes a product processing business process template, and the product processing business process template includes a material assembly verification action, a material binding reporting action and a quality parameter update action under a product processing business scenario, and the operation logic corresponding to each action; wherein,

[0150] The operation logic corresponding to each action in the product processing business process template is:

[0151] Obtain the assembled material code corresponding to the target product and perform material verification, obtain the material verification result and upload it to the controller; the material verification at least includes whether the material meets the material BOM requirements of the product model and whether the material length meets the requirements;

[0152] Process the target product, obtain the finished product, bind it with the material information and upload it to a third-party system;

[0153] After the quality parameter update signal triggered by the controller is monitored, the quality parameters of the finished product are collected and stored, and the product status is determined and sent to the controller.

[0154] Specifically, the interactive process of the product processing business scenarios:

[0155] 1. Material assembly verification: Scan the material code, and the system will verify the material to determine whether the material meets the material BOM requirements of the product model, whether the material length meets the requirements, etc. The LMES system will feedback the results to the PLC;

[0156] 2. Material binding reporting: reporting the binding information of the assembly product and the material to the third-party system;

[0157] 3. Quality parameter update: After the PLC stores the quality parameters in the register, it triggers the quality parameter update signal, notifying the LMES system to collect and store the quality parameters and make product status judgments and send them to the PLC. Supplementary explanation: Since some processes support repeated processing or repeated testing of products, it is necessary to perform a cyclic interaction of the quality parameter update process. After each processing, the system is required to feedback to the manufacturing specialist what quality parameters of the current product are unqualified and guide the operator on how to repeat the processing.

[0158] Please refer to Figure 6 , the product goes on the conveyor belt, and is processed from the first process OP10 according to the process route requirements, and is processed and finished at the last process OP90. If there is any production abnormality during the process, it will be discharged from the production line to the defective product storage area through the discharge port. Specifically, after the product goes on the conveyor belt, it is processed from the OP10 process until the last process OP90 is completed and it goes off the line. Each process station processing in the warehouse must initiate an entry application to the LMES system. The LMES system issues the entry result and the specific equipment processing process can only be carried out after it is OK; when the product is processed, whether the interactive process needs to be added depends on the production content of the process and the requirements of EU customers; after the product is processed at each process station, it is necessary to initiate an exit application to the LMES system. The LMES system collects quality parameters, judges the product status, and issues the exit result. When the product is OK, it continues to be processed in the next process. When it is NG, it is discharged to the nearest abnormal product discharge port.

[0159] In one embodiment, the product process template at least includes a label printing business process template, and the label printing business process template includes a barcode generation action and a label transcoding printing action in a label printing business scenario and the operation logic corresponding to each action; wherein,

[0160] The operation logic corresponding to each action in the label printing business process template is:

[0161] After the barcode generation signal is detected to be triggered, a product code is generated according to the barcode generation rules;

[0162] After the barcode printing signal is detected to be triggered, the product code is read and parsed, and the parsing result is converted according to the transcoding rule to obtain a label and print it.

[0163] In addition, product process templates may also include material assembly inspection business process templates, process formula distribution business process templates, binding update code business process templates, etc., which are not listed here one by one.
