Description

Technical Field

[0001] The present invention relates to a method for processing technical documents, and in particular to a method for intelligently transmitting transmission product technical parameter information based on a PLM system. Background Art

[0002] In order to meet the intelligent production needs of the future market, transmission manufacturers need to formulate a smart factory plan to improve the processing capabilities of transmission series products. To achieve this plan, it is necessary to open up the entire process of the entire intelligent production line from flexible data entry to application management, and then realize the standardization, structuring and digitization of all product technical parameter information related to transmission production. Otherwise, the upstream data will not be able to support the acquisition of downstream production information, resulting in the inability to successfully complete the production task of the smart factory.

[0003] At present, after the manufacturer sends the paper version of the technical agreement to the transmission manufacturer, it needs to be confirmed and translated into a recognizable agreement template by the relevant personnel. After investigation, it was found that the technical agreement templates of various manufacturers are not the same, and the descriptions of certain parameters in the templates are also different. In the process of translating the template, the parameter information needs to be filled in manually, resulting in a low degree of intelligence and an increased probability of error. In addition, because there is no structured data in the template, the corresponding product parameters cannot be extracted and sent to the downstream system for use.

[0004] The Chinese invention patent with publication number CN110956029A discloses a method and system for processing technical documents, which is mainly oriented to user usage scenarios and integrates the preparation and application process of technical documents, relevant reference standards, knowledge and skills, case libraries, material libraries, and tool software used in the process into a software system for generating and applying technical documents according to user characteristics. However, the system focuses on the standardized preparation of technical documents, but does not mention how to extract relevant technical parameters from technical documents. Therefore, the method and system still have the aforementioned problems.

[0005] In addition, the existing document management systems have relatively simple functions and are mostly pure document processing. They are unable to extract multi-platform technical data, BOM parameters of the PDM system, multi-database parameters, etc. and complete the automatic conversion of downstream production documents. Therefore, they are also unable to realize intelligent production. Summary of the invention

[0006] The purpose of the present invention is to solve the technical problems that the prior art has low intelligence and is prone to errors, and is unable to extract the corresponding product parameters and complete automatic conversion, and to provide a method for intelligently transmitting transmission product technical parameter information based on a PLM system.

[0007] To achieve the above objectives, the technical solutions provided by the present invention are:

[0008] A method for intelligently transmitting transmission product technical parameter information based on a PLM system, which is special in that it includes the following steps:

[0009] Step [1]: Establish a model database, a feature database, and a protocol template database in the PLM system, and pre-store fixed parameter information of each product in the model database, pre-store specific requirements of known customers for corresponding product models in the feature database, and store technical protocol templates of corresponding products according to product models in the protocol template database;

[0010] Step [2]: Receive the technical agreement from the customer, enter the customer information and product model into the PLM system, and let the PLM system determine whether there are new specific requirements in the agreement. If so, update the feature library and proceed to step [3]. If not, proceed directly to step [3].

[0011] Step [3], the PLM system extracts fixed parameter information and specific requirements corresponding to the product in the technical agreement in step [2] from the model database and feature database, respectively, and forms a corresponding BOM table after configuring parameters according to the technical agreement; the BOM table includes material category, name and quantity;

[0012] Step [4]: ​​The PLM system extracts the technical agreement template corresponding to the product in the technical agreement from the agreement template library, and generates a webpage technical agreement after extracting the corresponding data information from the BOM table;

[0013] Step [5]: Combine the webpage technical protocol and the model library to generate the corresponding packing instruction document and structured information respectively, and the PLM system sends the packing instruction document and structured information to the downstream system respectively, thereby realizing the intelligent transmission of the transmission product technical parameter information.

[0014] Furthermore, in step [1], the model spectrum library needs to be updated in real time after the new creation process is completed according to the product base model.

[0015] Furthermore, in step [1], the feature library is defined in the form of special description common terms, and at the same time establishes an association with the customer code to achieve a one-to-one correspondence between the customer and the customer's special requirements.

[0016] Furthermore, in step [1], the protocol template library supports multi-role editing, and each role is only allowed to edit the content related to it in the technical protocol template.

[0017] Furthermore, in step [4], while the web page technology protocol is generated, an empty installation dimension drawing document is also generated.

[0018] Furthermore, step [4] also includes the step of checking the webpage technical agreement according to the content of the user technical agreement. If the check is qualified, proceed to step [5]; otherwise, the webpage technical agreement is adjusted according to the content of the user technical agreement, and then proceed to step [5].

[0019] Furthermore, in step [5], the downstream system includes a production and manufacturing platform and a process platform; wherein the packing instruction document is sent from the PLM system to the production and manufacturing platform, and the structured information is sent from the PLM system to the process platform; the structured information includes inherent parameter values ​​of product parts, specific requirements, product assembly attribute values ​​and external component matching parameter information required by the process platform, and is sent to the process platform one by one in the form of data.

[0020] Furthermore, step [5] specifically includes, combining the webpage technical protocol and the model database, obtaining the packing instruction document and structured information respectively, and by querying the customer code, associating the packing instruction document and structured information with the customer code respectively, generating the corresponding packing instruction document and structured information, and the PLM system sends the corresponding packing instruction document and structured information to the downstream system respectively, thereby realizing the intelligent transmission of the transmission product technical parameter information.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention establishes a model library, a feature library and a protocol template library in the PLM system, and stores corresponding information in advance. When receiving the customer's technical agreement, the corresponding information is extracted from the corresponding library, and then combined with the corresponding technical agreement template to form a web page technical agreement. Finally, the required packing description document and structured information are generated and transmitted to the downstream system, so as to realize the intelligent transmission of product technical parameter information. This method can accurately extract product parameter information and transmit it to the corresponding downstream system through the PLM system. It has a high degree of intelligence and greatly improves the efficiency of information transmission.

[0023] 2. The present invention realizes the integrity of the type spectrum library information by updating the type spectrum library in real time, ensuring that it matches the parameter information in the customer's technical agreement, thereby improving the efficiency and accuracy of information extraction.

[0024] 3. The present invention establishes an association between the special requirements in the feature library and the customer code, thereby realizing a one-to-one correspondence between the customer and his special requirements, thereby reducing the error rate of information extraction.

[0025] 4. The protocol template library of the present invention supports multi-role editing, and each role is only allowed to edit the content related to it in the technical protocol template. By setting the opening and control of permissions, not only can the real-time update of the technical protocol template be achieved, but also erroneous input can be avoided, thereby reducing the probability of errors.

[0026] 5. The present invention associates the packing description document and structured information with the customer code respectively. By querying the customer code, the corresponding information can be quickly queried and obtained, thereby improving the query efficiency and reducing the workload of the information administrator.

[0027] 6. The intelligent transmission method of product technical parameter information based on the PLM system of the present invention only needs to enter customer information and product model into the PLM system to carry out the subsequent information extraction and transmission process, which reduces the amount of information input manually and significantly improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 1 Schematic diagram of a flow chart of an embodiment of the present invention. DETAILED DESCRIPTION

[0029] In order to make the purpose, advantages and features of the present invention clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0030] like Figure 1 As shown, a method for intelligently transmitting transmission product technical parameter information based on a PLM system includes the following steps:

[0031] Step [1]: Establish a model library, feature library and protocol template library in the PLM system respectively, and store the model library, feature library and protocol template library in the form of a configurable form or a structured configuration database in the background of the PLM system, and then perform the following operations:

[0032] The fixed parameter information of each product is pre-stored in the model database. The model database needs to be updated in real time after the new process is completed according to the product base model, so as to realize dynamic loading of data and realize one-time maintenance of material attributes and multiple uses, thereby reducing workload.

[0033] The known customer's specific requirements for the corresponding model products are pre-stored in the feature library. The feature library can be defined in the form of special instructions and commonly used terms, and at the same time establish an association with the customer code to achieve a one-to-one correspondence between customers and their special requirements, so as to accurately retrieve the corresponding special requirements. At the same time, the feature library is updated in real time according to customer needs.

[0034] The technical agreement templates of corresponding products are stored in the agreement template library according to the product models, and one technical agreement template can be bound to multiple product types, thereby meeting the requirement that multiple product models share one technical agreement template.

[0035] It should be noted that the above-mentioned spectrum library, feature library and protocol template library are all equipped with permission management mechanism and automatic storage mechanism. The protocol template library supports multi-role collaborative editing, but each role is only allowed to edit the content related to it in the technical protocol template to prevent misoperation.

[0036] Step [2]: Receive the technical agreement (paper version) from the customer. The corresponding staff will enter the customer information and product model mentioned in the technical agreement into the PLM system. The PLM system will determine whether there are new specific requirements in the agreement. If so, update the feature library and proceed to step [3]. If not, go directly to step [3].

[0037] Step [3], the PLM system extracts the fixed parameter information and specific requirements corresponding to the product in the technical agreement described in step [2] from the model library and feature library, and forms a corresponding BOM table after configuring the parameters according to the content of the technical agreement. The BOM table generally includes information such as material category, name and quantity. The PLM system supports advanced search and classification search functions to achieve rapid material search.

[0038] Step [4]: ​​The PLM system extracts the technical agreement template corresponding to the product in the technical agreement from the agreement template library, and generates the webpage technical agreement after extracting the corresponding data information from the BOM table. In order to improve the accuracy of the content of the webpage technical agreement, it is generally necessary to check the webpage technical agreement according to the content of the user technical agreement. If the check is qualified, it means that the content of the agreement is correct, and then proceed to step [5]. If it is unqualified, the webpage technical agreement is adjusted accordingly according to the content of the user technical agreement until it is accurate and then proceed to step [5].

[0039] In this embodiment, when a document is created and generated, the support system automatically starts the approval process, and the approval process node background can be configured according to needs. When a document needs to be changed, it can be revised and edited again. After revision, the system automatically restarts the document publishing process, and the node is consistent with the initial publishing process.

[0040] In addition, while generating the web page technical agreement, the PLM system also generates an empty installation dimension drawing document. Its code is automatically generated according to user requirements and associated with the material. After the engineer completes the formal document, the installation dimension drawing document is edited and provided to the customer for the customer to verify the overall dimension chain of the product.

[0041] Step [5]: Combine the web technical protocol and the model database to generate corresponding packing instruction documents and structured information. The PLM system will send the packing instruction documents to the production and manufacturing platform (generally the ERP system) and the structured information to the process platform (generally the TCM system), thereby realizing the intelligent transmission of transmission product technical parameter information.

[0042] The structured information includes the inherent parameter values ​​of product components, specific requirements, product assembly attribute values ​​and external parts matching parameter information required by the process platform, and is sent to the process platform one by one in the form of data.

[0043] In this embodiment, the packing instruction document and structured information can also be associated with the customer code respectively, and the corresponding packing instruction document and structured information can be obtained by querying the customer code, so as to dynamically generate product user technical requirements that meet the customer's format requirements.

[0044] In addition, documents or information in the working or reworking state will be automatically upgraded to a smaller version after being checked into the PLM system through the structured editor. For published documents, only viewing permissions are available. If modifications are required, they can be revised manually. After revision, the document will be upgraded to a larger version and become in the working state, and can then be modified and edited through the structured editor.

[0045] The present invention parameterizes and standardizes the characteristic parameters (order information, protocol information, OEM information, attributes of various transmission components, special assembly requirements, etc.) in the technical parameter information of a series of transmission products in the PLM system, and transforms the data from the current information document management mode to the information structured management mode (i.e., converting the traditional language into a recognizable computer language), thereby realizing the free call and management of each piece of information, and realizing multi-mode transmission from the PLM system to the TCM system and the ERP system (the PLM system to the TCM system realizes the piece-by-piece transmission of information, and the PLM system to the ERP system maintains the existing information document transmission). On this basis, the TCM system can transmit the assembly requirements of each order transmitted by the PLM system to the MES system for different workstations, and finally realize the display of the assembly requirements of the corresponding workstation on the terminals of different workstations in the production line of the smart factory, thereby meeting the requirements of high-level liberalized assembly and improving the management level of transmission product data.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present invention.
