Description

Technical Field

[0001] This invention relates to intelligent manufacturing technology, specifically to a production line quality control method and system based on the Industrial Internet of Things. Background Technology

[0002] With the development of intelligent manufacturing technology, the production model of the manufacturing industry is trending towards informatization, intelligence, and digitalization. As market competition intensifies and informatization accelerates, the requirements for product quality are becoming increasingly stringent. Manufacturing is the process of transforming manufacturing resources (materials, equipment, tools, capital, technology, information, etc.) into products that are usable and usable by people, according to market demands. In manufacturing, product quality is inseparable from both the design and manufacturing stages. As a crucial component affecting product quality, quality management and quality control in the manufacturing stage are indispensable links in ensuring product quality. Currently, many discrete manufacturing industries produce products with complex structures and numerous uncertainties in the production process, yet they still rely on traditional paper-based information documents to record historical data. This results in the inability to collect large amounts of data in real time, fragmented information, and ineffective assurance of accuracy, which seriously affects the control of product quality in discrete manufacturing. Summary of the Invention

[0003] The purpose of this invention is to address the problems of inability to collect large amounts of data in real time, fragmented information, and inability to guarantee accuracy caused by the traditional paper-based information document recording system used in discrete manufacturing. This invention provides a production line quality control method based on the Industrial Internet of Things (IIoT), which facilitates the recording and querying of historical data, centralizes information, and ensures accuracy. This invention also discloses a system for implementing the above-mentioned production line quality control method based on the IIoT.

[0004] The objective of this invention is mainly achieved through the following technical solutions:

[0005] The production line quality control method based on the Industrial Internet of Things (IIoT) is implemented through sequential interaction of a user platform, a service platform, a management platform, a sensor network platform, and an object platform. There are multiple object platforms, and each product processed by an object platform is equipped with an associated electronic tag. The electronic tag stores product source information and product parameter information corresponding to its associated product. Each object platform includes production line equipment performing manufacturing, production line sensors performing product data acquisition, and readers / writers performing electronic tag data acquisition and writing. The method includes the following steps:

[0006] Step S1: The object platform reads the product source information and product parameter information of the product to be processed stored in the electronic tag associated with the product to be processed through its reader and sends it to the management platform through the sensor network platform.

[0007] Step S2: The management platform receives, processes, and stores the product source information and product parameter information of the product to be processed, and then sends the product source information and product parameter information of the product to be processed to the service platform.

[0008] Step S3: The service platform receives the product source information and product parameter information of the product to be processed. It compares the product source information and product parameter information of the product to be processed with the product source information and product parameter information pre-stored in the service platform. If the comparison is consistent, the service platform generates a successful information comparison instruction and sends it to the object platform sequentially through the management platform and the sensor network platform. The object platform receives the successful information comparison instruction and completes the processing of the product to be processed through its production line equipment, proceeding to the next step. If the comparison is inconsistent, the service platform generates a failed information comparison instruction and sends it to the object platform sequentially through the management platform and the sensor network platform. The object platform receives the failed information comparison instruction and abandons the processing of the product to be processed that failed the current information comparison. The service platform also generates information comparison failure information corresponding to the process of the product to be processed that failed the current information comparison and feeds it back to the user platform. The user platform receives the information comparison failure information and displays it to the user.

[0009] Step S4: After the object platform completes the processing of the product to be processed, it collects the parameter information of the product that has been processed in the current process through its production line sensors and sends it to the management platform via the sensor network platform. The management platform receives the parameter information of the product that has been processed in the current process, generates a product number, stores the information, and then generates a write instruction for writing the process number corresponding to the current process, the parameter information of the product that has been processed in the current process, and the product number, and sends it to the reader. The reader receives the write instruction and writes the process number corresponding to the current process, the parameter information of the product that has been processed in the current process, and the product number into the electronic tag associated with the product that has been processed in the current process.

[0010] Furthermore, the service platform adopts a post-decentralized layout, which means that the service platform has a main platform and multiple sub-platforms. Each sub-platform corresponds one-to-one with the object platform corresponding to each process in the production line. Control information and object platform parameter configuration information are transmitted from the sub-platforms to the main platform, while sensing information is transmitted from the main platform to the sub-platforms. The product source information and product parameter information pre-stored in the service platform are stored in the sub-platforms. Each sub-platform corresponds to storing the product source information and product parameter information of the product processed by one object platform. The service platform receives the product source information and product parameter information of the product to be processed through its main platform and sends it to the corresponding sub-platform. The service platform compares the product source information and product parameter information of the product to be processed with the pre-stored product source information and product parameter information on its sub-platforms.

[0011] Both the management platform and the sensor network platform are deployed independently. This independent deployment means that the platform has multiple sub-platforms, each corresponding to an object platform for data storage, data processing, and / or data transmission. Each sub-platform of the management platform independently receives and processes the sensing information and parameter configuration instructions of its corresponding object platform. Each sub-platform of the sensor network platform independently realizes information transmission between a sub-platform of the management platform and its corresponding object platform.

[0012] Furthermore, before comparing the product source information and product parameter information of the product to be processed with the product source information and product parameter information pre-stored in the service platform in step S3, the service platform also includes the following steps: The service platform confirms whether the current process of the product to be processed is the first process. If it is the first process, the information comparison step is performed; otherwise, the service platform generates a product number verification instruction and sends it to the management platform corresponding to the process number of the process above the current process of the product to be processed. The management platform receives the product number verification instruction and performs product number verification. If a matching product number is found, a verification confirmation instruction is generated and sent to the service platform. The service platform receives the verification confirmation instruction and performs the information comparison step. If a matching product number is not found, the management platform generates a verification failure instruction and sends it to the service platform. The service platform receives the verification failure instruction and stops the information comparison step. The service platform generates verification failure information containing the product number of the product to be processed and the process number of the product to be processed and feeds it back to the user platform. The user platform receives the verification failure information and displays it to the user.

[0013] Furthermore, in step S3, when the service platform compares the product source information of the product to be processed with the product source information stored in the service platform, if it is the first process, the product source information is the manufacturer and product model corresponding to the product; if it is not the first process, the product source information is the process number of the previous process. When the service platform compares the product parameter information of the product to be processed with the product parameter information stored in the service platform, if all the deviations of the compared values ​​are within the set threshold range, it is confirmed that the comparison is consistent.

[0014] Furthermore, when the product to be processed by the object platform is split into multiple products after processing, the object platform configures an independent electronic tag for each processed product, and the reader writes the product source information and product parameter information of the processed product before processing into the newly configured electronic tag.

[0015] Furthermore, when the object platform processes products to be processed by assembling multiple products into one product, the object platform configures an independent electronic tag for each processed product, and the reader writes all product source information and product parameter information of the processed product before processing into the newly configured electronic tag.

[0016] The above-mentioned production line quality control method based on the Industrial Internet of Things includes a user platform, a service platform, a management platform, a sensor network platform, and an object platform that interact sequentially; characterized in that there are multiple object platforms, and each product processed by the object platform is equipped with an associated electronic tag, which stores product source information and product parameter information corresponding to the associated product;

[0017] The user platform is configured as a terminal device for interacting with users, receiving user input information, generating instructions and sending them to the service platform, and displaying information sent by the service platform to users; it also receives information comparison failure information and displays it to users.

[0018] The service platform, configured as the first server, receives and processes instructions sent by the user platform before sending them to the management platform, and retrieves information required by the user from the management platform and sends it to the user platform. It receives product source information and product parameter information of the product to be processed, and compares this information with pre-stored product source information and product parameter information on the service platform. If the comparison matches, the service platform generates a successful comparison instruction, which is then sent sequentially through the management platform and the sensor network platform to the target platform. The target platform receives the successful comparison instruction and completes the processing of the product to be processed through its production line equipment, proceeding to the next step. If the comparison does not match, the service platform generates a failed comparison instruction, which is then sent sequentially through the management platform and the sensor network platform to the target platform. It also generates information comparison failure information corresponding to the current failed process of the product to be processed and feeds it back to the user platform.

[0019] The management platform, configured as a second server, receives instructions sent by the service platform and controls the operation of the object platform according to the instructions; receives and stores the sensing information sent by the object platform; receives, processes, and stores the product source information and product parameter information of the products to be processed, and then sends the product source information and product parameter information of the products to be processed to the service platform; receives the parameter information of the products that have been processed in the current process, generates a product number, stores the information, and then generates a write instruction for writing the process number corresponding to the current process, the parameter information of the products that have been processed in the current process, and the product number, and sends it to the reader / writer;

[0020] The sensor network platform is configured as a communication network and gateway for interaction between the management platform and the object platform;

[0021] The object platform includes production line equipment for manufacturing, production line sensors for product data acquisition, and readers for electronic tag data acquisition and writing. It receives instructions from the management platform and sends sensing information to the management platform via the sensor network platform. The object platform uses its readers to read the product source information and product parameter information of the products to be processed from the electronic tags associated with those products, and sends this information to the management platform via the sensor network platform. The object platform receives a failure message for information comparison and abandons processing of products for which the current information comparison failed. After processing a product, the object platform uses its production line sensors to collect parameter information of the products already processed in the current process and sends it to the management platform via the sensor network platform. The readers receive a write instruction and write the process number corresponding to the current process, the parameter information of the products already processed in the current process, and the product number into the electronic tag associated with the product already processed in the current process.

[0022] In summary, the present invention has the following advantages compared with the prior art: (1) The present invention configures an independent electronic tag for each product, configures a reader / writer for each object platform, and centrally manages the production line based on the system structure composed of user platform, service platform, management platform, sensor network platform and object platform. The present invention enables unified collection and management of production line product information, which facilitates recording and querying of history data. The information is centralized, the accuracy is guaranteed, and it is easy to trace the root cause of quality problems when they occur. The present invention verifies the product information of the materials taken before processing products on each object platform, which can avoid the waste of resources caused by misuse and misappropriation of resources and can more effectively save production costs.

[0023] (2) The service platform of this invention adopts a distributed layout, with each sub-platform independently managing one object platform. The service platform compares the product source information and product parameter information of the product to be processed with the product source information and product parameter information pre-stored in the service platform on its sub-platform, making information comparison more efficient when applying this invention. The main platform of the service platform focuses on information interaction with the various sub-platforms of the management platform to reduce the operational load of the sub-platforms. Both the management platform and the sensor network platform of this invention adopt an independent layout. Each sub-platform of the management platform manages information for one object platform, allowing for independent management of each object platform, facilitating information retrieval and management for each object platform, and also facilitating data writing into the product's electronic tag. The sensor network platform of this invention is used for information interaction between the management platform and all object platforms in the production line. Each management platform transmits information to the object platform through a sensor network platform, making information transmission more efficient and improving the efficiency of electronic tag information reading and writing.

[0027] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0028] Example 1:

[0029] like Figure 1 As shown, the production line quality control system based on the Industrial Internet of Things includes a user platform, a service platform, a management platform, a sensor network platform, and an object platform that interact sequentially. There are multiple object platforms, and each object platform corresponds to a process. Each product processed by an object platform is equipped with an associated electronic tag, which stores product source information and product parameter information corresponding to its associated product. The user platform is configured as a terminal device for interacting with users, receiving user input information, generating instructions and sending them to the service platform, and displaying information sent by the service platform to the user. The service platform is configured as a first server, receiving instructions sent by the user platform, processing them and sending them to the management platform, and obtaining information required by the user from the management platform and sending it to the user platform. The management platform is configured as a second server, receiving instructions sent by the service platform and controlling the operation of the object platform according to the instructions, and receiving and storing sensing information sent by the object platform. The sensor network platform is configured as a communication network and gateway for interaction between the management platform and the object platform. The object platform includes production line equipment for manufacturing, production line sensors for product data acquisition, and readers for electronic tag data acquisition and writing, receives instructions from the management platform to operate, and sends sensing information to the management platform through the sensor network platform. In this embodiment, the production line equipment that performs manufacturing and the production line sensors that collect product data for each process are determined according to the products processed in the specific process. The production line equipment and production line sensors configured in existing intelligent manufacturing industrial production lines are relatively mature, and will not be described in detail in this embodiment. The reader and electronic tag in this embodiment are also based on existing technology.

[0030] In this embodiment, the user platform utilizes intelligent electronic devices such as desktop computers, tablets, laptops, and mobile phones for data processing and communication, without further limitation. In this embodiment, the data processing of each platform can be handled by the processor of the terminal device and / or the server. The server is equipped with a corresponding database for data storage, which can be stored on the server's storage device, such as a hard drive. In this embodiment, the parameters of the target platform can be configured according to the user-input target platform parameter configuration information. In this embodiment, during instruction transmission, each platform processes the received instructions into a pre-defined data packet format easily recognizable by the next-level receiving object. This embodiment builds different business and management systems on different platforms, using a unified protocol to ensure secure, efficient, and timely transmission and operation of data and information, forming an organic whole.

[0031] like Figure 2As shown, this embodiment includes the following steps: Step S1: The object platform reads the product source information and product parameter information of the product to be processed from the electronic tag associated with the product to be processed through its reader, and sends it to the management platform through the sensor network platform; Step S2: The management platform receives, processes, and stores the product source information and product parameter information of the product to be processed, and then sends the product source information and product parameter information of the product to be processed to the service platform; Step S3: The service platform receives the product source information and product parameter information of the product to be processed, compares the product source information and product parameter information of the product to be processed with the product source information and product parameter information pre-stored in the service platform. If the comparison is consistent, the service platform generates an information comparison success instruction and sends it to the object platform through the management platform and the sensor network platform in sequence. The object platform receives the information comparison success instruction and completes the processing of the product to be processed through its production line equipment, and proceeds to the next step; if the comparison is inconsistent, the service platform generates an information comparison failure instruction and sends it to the management platform in sequence. The sensor network platform sends information to the object platform. The object platform receives the information comparison failure instruction and abandons processing the product to be processed for which the information comparison failed. The service platform also generates information comparison failure information corresponding to the process of the product to be processed for which the information comparison failed and feeds it back to the user platform. The user platform receives the information comparison failure information and displays it to the user. Step S4: After the object platform completes the processing of the product to be processed, it collects the parameter information of the product that has been processed in the current process through its production line sensors and sends it to the management platform via the sensor network platform. The management platform receives the parameter information of the product that has been processed in the current process, generates a product number, stores the information, and then generates a write instruction for writing the process number corresponding to the current process, the parameter information of the product that has been processed in the current process, and the product number, and sends it to the reader. The reader receives the write instruction and writes the process number corresponding to the current process, the parameter information of the product that has been processed in the current process, and the product number into the electronic tag associated with the product that has been processed in the current process. In this embodiment, the product source information and product parameter information pre-stored by the service platform are information configured by the user through the user platform and are preset before the system is used in this embodiment.

[0032] In discrete manufacturing, production lines are often discontinuous. To ensure production efficiency, multiple production line devices typically process the same product at a specific stage. This embodiment verifies the product's origin and parameters before processing on each production line device on each platform. This avoids misuse or misapplication of products and ensures that the quality of materials sourced before processing meets requirements. Furthermore, this embodiment centrally manages product history data. Each product's associated electronic tag records its history data, which is more convenient for recording and querying than traditional paper-based records. Centralized information ensures accuracy.

[0033] Example 2:

[0034] This embodiment further defines the service platform based on Embodiment 1 as follows: The service platform in this embodiment adopts a post-decentralized layout. This post-decentralized layout means that the service platform has a main platform and multiple sub-platforms. Each sub-platform corresponds one-to-one with the object platform corresponding to each process in the production line. Control information and object platform parameter configuration information are transmitted from the sub-platforms to the main platform, while sensing information is transmitted from the main platform to the sub-platforms. In this embodiment, the main platform of the service platform is configured as a first master server, and its sub-platforms are configured as first sub-servers. The main platform receives and processes data based on the first master server, and the sub-platforms receive and process data based on the first sub-servers. The service platform in this embodiment stores pre-stored product source information and product parameter information within the sub-platforms. Each sub-platform stores product source information and product parameter information corresponding to the product processed by an object platform. The service platform receives the product source information and product parameter information of the product to be processed through its main platform and sends it to the corresponding sub-platform. The service platform compares the product source information and product parameter information of the product to be processed with the pre-stored product source information and product parameter information on its sub-platforms.

[0035] In this embodiment, both the management platform and the sensor network platform are deployed independently. Independent deployment means the platform has multiple sub-platforms, each corresponding to an object platform for data storage, processing, and / or data transmission. The management platform is also deployed independently, with multiple sub-platforms, each implemented using an independent second sub-server, and each sub-platform corresponding to an object platform for data storage, processing, and / or data transmission. In this embodiment, each sub-platform of the management platform independently receives and processes the sensing information and parameter configuration instructions from its corresponding object platform. Similarly, the sensor network platform is deployed independently, with multiple sub-platforms, each implemented using an independent gateway server. In this embodiment, each sub-platform of the sensor network platform independently enables information transmission between one of the management platform's sub-platforms and its corresponding object platform.

[0036] In this embodiment, since the products to be processed on each object platform need to be compared with the product source information and product parameter information stored in the service platform, this embodiment sets the service platform into multiple sub-platforms. Each sub-platform of the service platform verifies the products to be processed on one object platform, which can improve the efficiency of information comparison and reduce the impact of information comparison on production efficiency.

[0037] Example 3:

[0038] This embodiment further defines the following aspects based on Embodiment 1 or Embodiment 2: Before comparing the product source information and product parameter information of the product to be processed with the product source information and product parameter information pre-stored in the service platform, the service platform in this embodiment includes the following steps: The service platform confirms whether the current process of the product to be processed is the first process. If it is the first process, an information comparison step is performed; otherwise, the service platform generates a product number verification instruction and sends it to the management platform corresponding to the process number of the process above the current process of the product to be processed. The management platform receives the product number verification instruction and performs product number verification. If a matching product number is found, a verification confirmation instruction is generated and sent to the service platform. The service platform receives the verification confirmation instruction and performs the information comparison step. If a matching product number is not found, the management platform generates a verification failure instruction and sends it to the service platform. The service platform receives the verification failure instruction and stops performing the information comparison step. The service platform generates verification failure information containing the product number of the product to be processed and the process number of the product to be processed and feeds it back to the user platform. The user platform receives the verification failure information and displays it to the user.

[0039] Thus, when this embodiment is applied, by verifying the information of the product to be processed on the management platform corresponding to the previous process, which is not the first process, the origin of the product to be processed can be effectively verified, and the authenticity of the product source can be further determined, making the confirmation of product source information more standardized when this embodiment is applied.

[0040] Example 4:

[0041] This embodiment further defines the following limitations based on any one of embodiments 1 to 3: When the service platform compares the product source information of the product to be processed with the product source information pre-stored on the service platform, if it is the first process, the product source information is the manufacturer and product model corresponding to the product; if it is not the first process, the product source information is the process number of the previous process. When the service platform compares the product parameter information of the product to be processed with the product parameter information pre-stored on the service platform, if all the deviations of the compared values ​​are within the set threshold range, it is confirmed that the comparison is consistent. Because errors are difficult to avoid during the manufacturing process, this embodiment, by setting a deviation threshold, can avoid minor deviations from affecting the normal implementation of this embodiment while ensuring product quality.

[0042] Example 5:

[0043] This embodiment further defines the following based on any one of embodiments 1 to 4: When the product to be processed by the object platform in this embodiment is split into multiple products after processing, the object platform configures an independent electronic tag for each processed product. The reader writes the product source information and product parameter information of the processed product before processing into the newly configured electronic tag. Thus, when this embodiment is applied, it can ensure that each product entering the next process has an electronic tag containing its product source information and product parameter information, further ensuring that the corresponding information can be obtained before the information comparison is performed in the next process.

[0044] Example 6:

[0045] This embodiment further defines the following based on any one of embodiments 1 to 5: When the object platform in this embodiment processes multiple products to be processed into one product, the object platform configures an independent electronic tag for each processed product. The reader writes all product source information and product parameter information of the processed product before processing into the newly configured electronic tag. Thus, when this embodiment is applied, it ensures that the assembled product contains the product source information and product parameter information of the multiple products to be processed before assembly, facilitating the identification of quality problems during quality inspection.

5. A system for implementing the production line quality control method based on the Industrial Internet of Things as described in any one of claims 1 to 4, comprising a user platform, a service platform, a management platform, a sensor network platform, and an object platform that interact sequentially; characterized in that, There are multiple object platforms, and each product processed by an object platform is equipped with an associated electronic tag. The electronic tag stores product source information and product parameter information corresponding to the associated product. The user platform is configured as a terminal device for interacting with users, receiving user input information, generating instructions and sending them to the service platform, and displaying information sent by the service platform to users; it also receives information comparison failure information and displays it to users. The service platform is configured as the first server and adopts a distributed layout, with a main platform and multiple sub-platforms. The sub-platforms of the service platform correspond one-to-one with the object platforms corresponding to all processes in the production line. The product source information and product parameter information pre-stored in the service platform are stored in the sub-platforms, and each sub-platform corresponds to storing the product source information and product parameter information of the products processed by one object platform. The main platform of the service platform is configured to receive product source information and product parameter information of the products to be processed, and send them to the corresponding sub-platforms. The sub-platform of the service platform is configured to: receive product source information and product parameter information of the product to be processed; confirm whether the current process of the product to be processed is the first process; if it is the first process, compare the product source information and product parameter information of the product to be processed with the product source information and product parameter information pre-stored in the sub-platform; if it is not the first process, generate a product number verification instruction and send it to the management platform corresponding to the process number of the process above the current process of the product to be processed for product number verification; if a matching product number is found, perform the information comparison; if a matching product number is not found, stop the information comparison and generate a verification failure message to be fed back to the user platform. If the comparison matches, a successful information comparison instruction is generated and sent sequentially from the management platform and the sensor network platform to the target platform. If the comparison is inconsistent, an information comparison failure instruction is generated and sent sequentially through the management platform and the sensor network platform to the object platform; and information comparison failure information corresponding to the current information comparison failure of the product to be processed is generated and fed back to the user platform. The management platform, configured as a second server, is independently deployed and has multiple sub-platforms. Each sub-platform corresponds to an object platform for data storage, data processing, and / or data transmission. It receives instructions from the service platform and controls the operation of the object platform accordingly; it receives and stores sensing information sent by the object platform; it receives, processes, and stores product source information and product parameter information of the products to be processed, and then sends this information to the service platform; it receives parameter information of products already processed in the current process, generates a product number, stores the information, and then generates a write instruction for writing the process number corresponding to the current process, the parameter information of the products already processed in the current process, and the product number, sending this instruction to the reader; it receives product number verification instructions and performs product number verification. The sensor network platform is configured as a communication network and gateway for interaction between the management platform and the object platform. It is arranged independently and has multiple sub-platforms. Each sub-platform independently realizes information transmission between a sub-platform of the management platform and the corresponding object platform. The object platform includes production line equipment for manufacturing, production line sensors for product data acquisition, and readers for electronic tag data acquisition and writing. It receives instructions from the management platform and sends sensing information to the management platform via the sensor network platform. The object platform uses its readers to read the product source information and product parameter information of the products to be processed from the electronic tags associated with those products, and sends this information to the management platform via the sensor network platform. The object platform receives a failure message for information comparison and abandons processing of products for which the current information comparison failed. After processing a product, the object platform uses its production line sensors to collect parameter information of the products already processed in the current process and sends it to the management platform via the sensor network platform. The readers receive a write instruction and write the process number corresponding to the current process, the parameter information of the products already processed in the current process, and the product number into the electronic tag associated with the product already processed in the current process.
