Description

Technical Field

[0001] The present invention belongs to the field of information transmission, and in particular relates to an information transmission method and system for blades in a process of outsourced production. Background Art

[0002] During the outsourced production of steam turbine blades, material boxes must transmit massive amounts of production information, including process information, process parameters, and quality inspection data, in real time. Currently, the industry generally uses RFID (Radio Frequency Identification) tags or QR codes as information carriers to achieve cross-unit data transmission, but this technology has significant limitations in practice.

[0003] RFID tags are a common method for transmitting material information in logistics and transportation. Using RFID, the sending unit writes the material information corresponding to the material box onto the RFID tag, and the receiving unit directly reads the information from the RFID tag using an RFID reader / writer. However, this method suffers from high costs and limited capacity. Specifically, each material box in transit requires at least one RFID tag, and each collaborating unit must deploy a dedicated RFID reader / writer and supporting system, resulting in high hardware costs. Furthermore, RFID tags can become damaged during the transit process, further increasing maintenance costs. Furthermore, since the maximum storage capacity of commercially available RFID tags is only a few megabytes, the amount of information stored in the outsourced production of turbine blades is large. Due to the limited capacity of RFID tags, each material box must be equipped with two to three RFID tags to fully store data. As the number of material boxes increases, hardware costs increase significantly. Furthermore, if the information stored in the RFID tags needs to be read, the reader / writer must coordinate multiple tags, which is inconvenient for users and significantly reduces operational efficiency.

[0004] Regarding the use of QR code technology, material information is usually stored in the QR code by attaching it to each material box. The receiving unit scans the code to read the information in the QR code, and some encryption measures can be added. However, there are also disadvantages such as high cost, limited capacity, and easy damage. Specifically, the capacity of a one-dimensional barcode is 50 bytes, and the maximum capacity of a two-dimensional barcode can store 2 to 3,000 characters. However, if a large amount of information is stored in a QR code, the QR code size will be large, the density of the QR code will be high, and the readability will be poor. At the same time, in order to recognize high-density QR codes, the requirements for scanning equipment will be increased, which will increase hardware costs. Furthermore, if the QR code is contaminated or damaged during transportation, the readability will be even worse, and even the information will be lost. Based on the above, the amount of information stored in the information transmission scenario of the outsourced production process of turbine blades is large. Research has found that if QR codes are used, in order to store all the blade processing information in the box, the size of the QR code on each logistics box must be expanded to A4 format level, and non-conventional scanning equipment can read the QR code information. However, due to the larger size of the QR code, it is more likely to be damaged during the circulation and transportation of the material box, resulting in poor readability and even information loss. If high-resolution scanning equipment is used, the procurement cost will increase by 3-5 times compared with conventional scanning equipment, resulting in additional hardware investment burden. Summary of the Invention

[0023] The following will be combined with the appended Figure 1 ~Attached Figure 4 , the technical solutions, structural features, objectives achieved and effects in the embodiments of the present invention are described in detail.

[0024] It should be noted that the drawings are in a very simplified form and use non-precise proportions. They are only used to conveniently and clearly assist in explaining the embodiments of the present invention, and are not used to limit the conditions for the implementation of the present invention. Therefore, they have no substantive technical significance. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in the present invention without affecting the efficacy and purpose that can be achieved by the present invention.

[0025] It should be noted that, in the present invention, relational terms such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only the elements explicitly listed, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0026] like Figure 1 As shown, Figure 1 The process flow for the production of steam turbine blades specifically includes blank processing, fine processing, re-engraving, CNC processing, polishing, and completion quality inspection and packaging processes, wherein the blank processing is the front process in the entire production process of the blade. After the blank processing is completed, it must be returned to the factory for fine processing and other production processes. It should be noted that the blank processing of the first process is fixedly performed by an outsourced supplier, and the subsequent processes may be self-made or outsourced depending on the production capacity or other reasons. Furthermore, after the current outsourcing process is completed, it needs to be temporarily stored in the blade three-dimensional warehouse. Due to the imbalance in the processing capacity of each process in the factory, each self-made process in the factory also needs to be temporarily stored in the blade three-dimensional warehouse. The blades will be taken out of the blade three-dimensional warehouse when the next process is carried out. Therefore, in the production process of steam turbine blades, there are a large number of blade circulation and transmission processes.

[0027] Based on the above, an embodiment of the present invention provides an information transmission system for blades in a process of outsourcing production, such as Figure 2 As shown, it includes: a manufacturing execution platform 10 (MES, Manufacturing Execution System), an intelligent logistics platform 20 (iWMS) and an outsourcing packaging platform 30; the manufacturing execution platform 10 is connected to the intelligent logistics platform 20 and deployed in the factory; the manufacturing execution platform 10 is used to generate process outsourcing tasks and transmit them to the intelligent logistics platform 20, and the manufacturing execution platform 10 is responsible for the whole process of the blade (such as Figure 1The smart logistics platform 20 is connected to the blade stereoscopic warehouse 40, and is used to establish an outbound task according to the process outsourcing task, and determine the outbound blades based on the outbound task, and perform outbound by scanning the box code; and / or when the blade completes the process outsourcing task and returns to the warehouse, an inbound task is established, and the inbound operation is completed by scanning the box code and verifying and comparing it with the inbound task; that is, the smart logistics platform 20 is responsible for the storage and retrieval of each blade, as well as the management and control of the blade code list and blade information in each box of the blade. The blade stereoscopic warehouse 40 is used to store physical blades and pick and place blades according to the outbound task or the inbound task; and the entrance of the blade stereoscopic warehouse 40 is provided with a reading device (not shown in the figure) for scanning the box code.

[0028] Further, if Figure 2 As shown, the outsourcing packing platform 30 is connected to the smart logistics platform 20. As an optional embodiment, the outsourcing packing platform 30 is connected to the smart logistics platform 20 through an external network, and is used to scan the blades for outsourcing processing according to the process outsourcing task, and generate corresponding packing tasks. When the blade process outsourcing task is completed, the packing task is executed, and each box code and the corresponding blade code are associated according to the association logic to generate a blade code list and blade processing information for each material box, which are stored in the outsourcing packing platform. When the physical box is put into storage, the box code is scanned by the reading device at the entrance of the three-dimensional warehouse 40, and the blade code list and blade processing information associated with the corresponding box code are retrieved from the outsourcing packing platform and transmitted to the smart logistics platform 20. The outsourcing packing platform 30 can realize the online mapping of the blade code and the box code in the scanning and packing process, ensuring the consistency of the blade information after the process outsourcing task is completed and returned to the blade three-dimensional warehouse 40 with the data stored in the smart logistics platform 20.

[0029] In a specific embodiment, the supplier accesses the outsourcing packing platform 30 through a browser and performs front-end services (including process outsourcing task management, code scanning for packing, and code scanning for unpacking). The back-end services of the outsourcing packing platform 30 (blade information management and data transmission updates) are implemented through a server deployed within the factory.

[0030] The blade code is formed by encoding each blade. The blade code is engraved on the blade entity during the blank processing process. The blade code includes a blade QR code and a blade clear code. The blade QR code only stores the blade ID and no other information. The blade clear code, like the blade QR code, is only the blade ID, thus solving the problem of insufficient QR code information capacity. The blade clear code is the code engraved on the blade (i.e., the blade ID). The code content is the same as the blade ID content stored in the QR code. The encoding rules of the blade ID are encoded according to certain encoding rules.

[0031] During the entire blade production process, the blade's QR code is scanned to identify the blade's ID. This information is then updated in real time to the Manufacturing Execution Platform 10 and the Smart Logistics Platform 20. The information is then stored in a database via the Manufacturing Execution Platform 10 and the Smart Logistics Platform 20, ensuring consistency between the actual blade processing status and the online data. If the QR code on a blade is defaced or damaged, the blade's plain code, engraved on the blade, can be used to identify the current blade.

[0032] Furthermore, when the blades are transported to the outsourced supplier, they are loaded in a specific logistics box. Therefore, for each physical logistics box, a fixed box code is printed on each logistics box. The box code includes a box QR code and a box plain code, and the box QR code only stores the material box number information. The material box number information is consistent with the content represented by the box plain code, and does not store the specific material information in the box. In other words, the box plain code is the material box number. The blade code list and blade information of the blades in the material box are transmitted to the smart logistics platform 20 and stored in the database through the smart logistics platform 20. When the material box is in circulation, the blade code list and blade information in the smart logistics platform 20 are scanned to check the blade code and blade information in the current material box, so as to achieve consistency between the physical blades in the material box and the online database. When the box QR code is damaged, the blade information in the current material box can also be queried by entering the box plain code.

[0033] The box code is managed as basic configuration information on the smart logistics platform 20, which provides a query interface for the manufacturing execution platform 10 and the outsourced packaging platform 30. Each physical material box is uniquely associated with a box number. A box QR code and a box code containing the box number are imprinted on the physical material box. The box number uniquely identifies the box (e.g., Y02). This allows the blade code to be bound to the box code during packaging and unpacking operations during blade processing. In other embodiments, the information transmission system is not limited to the transmission of blade information.

[0034] The present invention also provides a method for transmitting information of blades in a process of outsourced production, which is implemented based on the above-mentioned information transmission system of blades in a process of outsourced production, and includes: engraving a corresponding blade code on each blade, and engraving a fixed box code on each material box used to load the blades; when the blades complete the process outsourcing task and are packed, the outsourcing packing platform 30 first scans the box code on the material box, and then scans the leaf code of each packed blade, and associates each box code with the corresponding leaf code according to the association logic to generate a leaf code list and leaf information for each material box, and stores them on the outsourcing packing platform 30; transmits them to the smart logistics platform 20; when the material box is in circulation, the corresponding leaf code list and leaf information are retrieved from the outsourcing packing platform 30 by scanning the box code on the material box, and the blades and their information stored in the current material box are determined; when the blades execute the process outsourcing task and are unpacked, the outsourcing packing platform 30 first scans the box code on the material box, and then scans the leaf code of each unpacked blade to obtain the leaf information, and executes the current process according to the leaf information.

[0035] Among them, the specific steps of engraving the blade code on the blade include: when the blade is undergoing the outsourcing task of the blank process, the manufacturing execution platform 10 generates a blade code list containing several of the blade codes, and transmits the blade code list to the outsourced supplier, and the outsourced supplier engraves each of the blade codes on the corresponding blade.

[0036] Among them, when the blade completes one or more outsourcing tasks for the process and is put into storage, the box code is scanned by a reading device (such as a camera) set at the entrance of the blade three-dimensional warehouse 40, and the blade code list is read from the outsourcing packing platform 30 and transmitted to the smart logistics platform 20. It is determined whether the smart logistics platform 20 has a storage task for the blade code list. If so, the blade is put into storage, and the blade information in the blade code list is read. The blade processing information corresponding to the blade code in the smart logistics platform 20 is updated to complete the blade storage operation. Further, after the blade is put into storage, the blade processing information corresponding to the blade code in the manufacturing execution platform 10 is updated according to the blade processing information in the smart logistics platform 20 to ensure that the blade processing information stored in the manufacturing platform 10 is consistent with the processing status of the physical blade, so as to facilitate the production and processing of subsequent processes. Among them, the blade processing information includes blade process information and processing process information; the blade process information includes the process route, the current process content, the content of the previous and subsequent processes; the processing process information includes the start time, end time, and quality inspection information of each process of the blade.

[0037] The outsourcing packaging platform 30 stores a blade-material box data table, which includes a blade column and a corresponding associated box column, as well as a material box column and a corresponding bill of materials column. The association logic between the blade code and the box code for packaging and unpacking includes:

[0038] During the packing process, the outsourced packing platform 30 scans and identifies the box code and blade code, assigns the associated box column of the blade to the corresponding box code, and assigns the material list column of the material box to the corresponding leaf code. That is to say, by scanning the box code, all the leaf codes contained in the material box can be identified, and all the leaf information can be obtained according to the leaf code, thereby realizing the transmission of leaf information.

[0039] During the outpacking process, the outsourced packing platform 30 scans and identifies the box code and leaf code, clears the box code corresponding to the associated box column of the leaf, and clears the leaf code corresponding to the material list column of the material box. That is to say, when the leaf is taken out of the material box, it means that the leaf is no longer placed in the material box, so the leaf code stored in the box code is cleared, and the box code corresponding to the leaf code is cleared, so that the two are untied and no longer associated with each other, to prevent confusion about the storage location of the leaf; at the same time, when the leaf is packed again, the leaf can replace the material box, and it is only necessary to bind the box code of the material box and the leaf code through association logic.

[0040] Furthermore, when completing the process outsourcing task for packing or preparing to execute the process outsourcing task for unpacking, the outsourcing packing platform 30 compares and verifies the leaf code obtained by scanning the code according to the leaf code list corresponding to the current process outsourcing task. If the verification result is that the leaf code is wrong or the leaf code is repeated, a prompt will be given immediately, which can effectively avoid leaf mismatching and thereby improve the accuracy of the packing or unpacking processing tasks.

[0041] In a specific implementation, take the outsourcing task of blade delivery as an example, Figure 3 As shown, it includes:

[0042] S11. The outsourcing planner initiates a process outsourcing task application, and the process outsourcing task application is approved, and S12 is executed;

[0043] S12. The manufacturing execution platform 10 generates a process outsourcing task based on the process outsourcing task application, transmits the process outsourcing task to the smart logistics platform 20 through the "allow outbound delivery" operation, and transmits the process outsourcing task to the blade outsourcing packaging platform 30; wherein the process outsourcing task includes a blade code list and blade process and processing information;

[0044] S13. The smart logistics platform 20 establishes an outbound task based on the outsourced task of the process, determines the outbound material box based on the outbound task, and performs outbound delivery by scanning the box code. Specifically, the smart logistics platform 20 determines whether there is an outbound task with the box code. If so, the outbound planner controls the blade stereoscopic warehouse 40 on the smart logistics platform 20 to deliver the blades according to the arrival of the transport vehicle. After the blades are delivered, they are transported to the outsourced supplier.

[0045] S14. The outsourcing packing platform 30 scans the blades for unpacking and processing according to the outsourcing task. Specifically, the smart logistics platform 20 pushes the blade code list to the "outsourcing packing platform" page of the corresponding outsourcing supplier based on the outsourcing task, forming a corresponding "outsourcing task" entry.

[0046] S15. The supplier scans the codes of the blades one by one according to the corresponding outsourcing tasks of the process and processes them out of the box. At the same time, the outsourcing packing platform 30 generates the corresponding packing tasks. Specifically, the outsourcing packing platform 30 first scans the box code on the material box, and then scans the leaf code of each blade shipped out of the box to obtain the leaf information, and executes the current process according to the leaf information. After steps S11 to S15, the blade outbound and outbound processing processes are completed.

[0047] Furthermore, in another embodiment, taking the example of blades being put into storage after completing outsourcing tasks, as shown in FIG. Figure 4 As shown, it includes:

[0048] S21. After the blade processing is completed, the outsourcing supplier performs the blade scanning and packing operation through the outsourcing packing platform 30. Specifically, the outsourcing packing platform 30 first scans the box code on the material box, then scans the leaf code of each packed leaf. According to the association logic, each box code is associated with the corresponding leaf code to generate a leaf code list and leaf information for each material box, and the list is stored in the blade outsourcing packing platform 30 and simultaneously transmitted to the smart logistics platform 20.

[0049] S22, the smart logistics platform 20 establishes a warehousing task based on the blade code list and blade information;

[0050] S23. When the blades are transported to the entrance of the blade storage system 40, a camera at the entrance scans the box code, retrieves the blade code list and blade processing information from the outsourced packing platform 30, and transmits it to the smart logistics platform 20, completing the warehousing operation. Specifically, the smart logistics platform 20 determines whether there is a warehousing task for the box code. If so, the box is put into storage, the blade code list and blade processing information associated with the material box are read, and the corresponding blade code and blade processing information are updated on the smart logistics platform 20, completing the warehousing operation.

[0051] In summary, the present invention provides a method and system for transmitting information about blades during outsourced production processes, which enables information interaction between an outsourced packaging platform 30 and an enterprise's internal smart logistics platform 20 and manufacturing execution platform 10, thus achieving real-time transmission of blade information. Furthermore, by engraving blade codes and box codes on blades and material boxes, the blade information is bound to the blade entity, reducing the probability of information transmission errors during the flow of blade entities during outsourced production processes at different stages. Furthermore, only a one-time manual development cost is required, and the outsourced packaging platform 30 can be used simultaneously by multiple suppliers.

[0052] Furthermore, the blade code and box code only include the blade ID and the material box number, and are not limited by the capacity of the information carrier. By setting dual readable codes of QR code and plain code, the risk of poor readability caused by contamination or damage of the QR code during transportation is reduced.

[0053] Although the present invention has been described in detail through the above preferred embodiments, it should be understood that the above description is not intended to limit the present invention. After reading the above description, various modifications and substitutions of the present invention will become apparent to those skilled in the art. Therefore, the scope of protection of the present invention should be defined by the appended claims.
