[0056] The following combines specific embodiments and the accompanying drawings of the specification to elaborate in detail on the technical solutions of the present invention.

[0057] As shown in the Figure 1 accompanying drawings, the present invention provides a tire lifecycle management system, including:

[0058] An SAP system, used for tire trial production;

[0059] The MDM system is used to create and obtain tire material data, create and maintain multiple data tables according to the attributes and stages of the tire material data, and input the tire material data into the corresponding data tables; optionally, the data tables are divided into film libraries, supplier libraries, compound libraries, large roll material libraries, green tire libraries, semi-finished product libraries, product libraries, and raw material libraries; optionally, the data tables automatically manage the data of the MDM system by adding triggers in the mysql database to ensure the consistency of the data in the data tables and the data in the MDM system.

[0060] The PLM system is used to retrieve the tire material data in the MDM system, create multi-level function modules according to the data tables and preset tire design requirements, and generate a formula structure table and / or a product structure table using the formula design module and the structure design module and send them to the SAP system; optionally, a synchronous data button is added to the PLM system to trigger the function of synchronizing the data in the data tables of the MDM system. Due to the large amount of data in the data tables, when the synchronous data button is clicked, only the changed data in the data tables is sent and updated, avoiding the problem of temporary system jams caused by a large amount of data entering the PLM system. At the same time, a scheduled task is added to set the PLM system to synchronize the data in the data tables at a fixed time every day.

[0061] Among them, the formula design module is used to create and obtain raw material data in the function module according to the data tables, set the basic formula table based on the preset formula standard, calculate the basic formula table according to the preset segmented calculation formula and the raw material input ratio, generate a formula structure table and upload it to the SAP system.

[0062] The structure design module is used to create and obtain product material data, green tire material data, and semi-finished product material data in the function module according to the data tables, design a material distribution map based on the preset overall tire standard and the preset tire contour standard, and perform construction and setup according to the preset forming equipment parameters, material distribution map, green tire material data, and semi-finished product material data to generate a product structure table and upload it to the SAP system.

[0063] The tire product is decomposed into formulas according to the product structure table, and the formulas are decomposed into raw materials according to the formula structure table. The raw materials are integratedly managed through the SAP system, and tire trial production is carried out according to the raw materials.

[0064] Through the collaborative work of the SAP system, MDM system, and PLM system, the above tire life cycle management system realizes the full-process integration from material data management, product design to production trial production, improves data consistency and work efficiency. The PLM system realizes the modularization and standardization of tire design through the formula design module and the structure design module, can quickly respond to different design requirements, and improves design efficiency. The SAP system integrally manages the raw materials to ensure the accurate supply and efficient utilization of materials during the trial production process, reducing the trial production cycle and cost.

[0065] In some embodiments of the present invention, the data table in the PLM system includes tire material data and a material number identifying the tire material data;

[0066] Get the material number and material data from the data table, create the lowest-level function module under the function module in the PLM system, select the material number and material data, and keep them consistent with the data in the data table through triggers.

[0067] Optionally, the multi-level functional modules can be divided into A-level functional modules, B-level functional modules and C-level functional modules. Basic data management, raw material management, large roll material management, formula design management, product data management, etc. are created in the A-level functional module; formula design, product information management, semi-finished product management, etc. are correspondingly created under the B-level functional module; C-level functional modules are continued to be created under the B-level functional module where sub-modules need to be continued to be created, such as creating C-level functional module formula design management under the B-level functional module formula design module; at the same time, data can be created in the lowest-level functional module as needed, such as product finished product information can be created under product information, material information can be selected from the corresponding data table, and the material number, material description, specification information, etc. are selected into the above-created product finished product information. The selected information is synchronized with the corresponding data table content by adding triggers in the MySQL database. Data that does not exist in the data table can be entered and saved in the PLM system; in addition, each level of functional module is independently named to ensure that there is no duplicate naming.

[0068] Each piece of material information in a functional module is assigned a serial number ID, and is used together with the name of the functional module in which it is located as a unique data number. For example, the ID of a finished product information in the product information is "product-1". When calling data, the functional module in which the material is located is located through the material ID information, and the corresponding data information is called.

[0069] By associating material numbers and material data, we ensure data accuracy and consistency, create the lowest-level functional modules in the PLM system, and flexibly adjust the design process according to needs. Through triggers, we keep the data in the PLM system consistent with that in the data table, reducing data errors and duplication of work.

[0070] As attached Figure 2 As shown, the recipe design module specifically includes:

[0071] Configure raw material prices, standards and categories according to raw material material data, generate raw material standard reports, formulate formula design targets based on preset formula standards, and configure basic formula tables based on formula design targets and raw material standard reports; optionally, fill in corresponding raw material categories, density, hardness, oil content, styrene content, ethylene content, static Tg, dynamic Tg, sulfur content, ash content and other related properties in the raw material standard reports; among them, raw material categories include rubber, filler, plasticizer, antioxidant and vulcanizer.

[0072] Calculate and update the phr statistics of raw materials according to the basic formula table, obtain the segmented formula table through the preset segmented calculation formula, calculate the formula cost according to the basic formula table and the preset segmented calculation formula, and generate the formula structure table after converting the raw material input ratio according to the segmented formula table.

[0073] Optionally, a formula code is defined in the PLM system, a formula design target is formulated based on a preset formula standard, and rubber material inspection project data is retrieved. The PLM system performs various types of formula design such as small-scale formulation, large-scale material, trial production and commissioning. The basic formula table configured based on the formula design target and the raw material standard report is shown in Table 1, wherein the types of raw materials include natural rubber-1, carbon black, active agent-stearic acid, heavy cyclohexane oil / rubber plasticizer, chemical antioxidant-antiaging agent, physical antioxidant-bimodal wax, accelerator, accelerator masterbatch, modified phenolic reinforcing resin, active agent-modified zinc oxide, long-acting alkylphenolic tackifying resin, anti-scorch agent, and insoluble sulfur;

[0074] By traversing all the raw materials in the basic formula table, the type of each raw material and the phr input value of the raw material are obtained, and the total number of parts by mass is summed up, and then the statistical value is updated according to the raw material category and its related attributes in the raw material standard report. If the raw material category is filler, it is accumulated to filler; if the raw material category is compound silane coupling agent, it is accumulated to silane;

By configuring the raw material prices, standards, and categories, a raw material standard report is generated to ensure that the formula design is based on a unified standard, improving the scientificity and consistency of the design. Based on the formula design objectives and the raw material standard report, the basic formula table is configured to make the formula design more targeted and operable, meeting specific performance requirements. Through standardized and goal-oriented design, the use of raw materials is optimized, the formula cost is reduced, and at the same time, the tire performance is ensured.

[0118] By classifying the semi-finished product material data by component and configuring the attributes, it is convenient for management and invocation, improving the design efficiency. Selecting the raw material formula of the semi-finished product material data according to the basic formula table and the formula code ensures the consistency between the semi-finished product design and the formula design. Through the modular semi-finished product design, the tire structure can be quickly adjusted and optimized to meet different requirements.

[0119] Perform component modular construction according to the component classification of the semi-finished product material data, calculate the tire semi-finished product data according to the preset forming equipment parameters to complete the tire semi-finished product construction, and add the finished product material number and the tire blank material number to generate the product structure table; optionally, calculating the tire semi-finished product data according to the preset forming equipment parameters includes:

[0120] Carcass weight = Skeleton weight + Rubber compound weight + Film weight;

[0121] Skeleton weight = Carcass width (substituted by semi-finished product) * Carcass length (input for forming) * Wire weight per square meter of cord fabric (substituted by cord fabric parameters, wire weight per square meter of cord fabric = Wire raw material weight per meter * Cord fabric density);

[0122] Rubber compound weight = Carcass width (substituted by semi-finished product) * Carcass length (input for forming) * Rubber weight per square meter of cord fabric [substituted by cord fabric parameters, rubber weight per square meter of cord fabric = (Cord fabric width * Cord fabric thickness - Cross-sectional area of wire * Wire density) * Rubber compound specific gravity];

[0123] Film weight = Film width (substituted by semi-finished product) * Film thickness (substituted by semi-finished product) * Film specific gravity (substituted by rubber compound formula information);

[0124] After the semi-finished product construction is completed, select the domestic and foreign sales material numbers of the semi-finished product during construction through the domestic and foreign sales attributes of the product material number in the product information library, and generate the corresponding product BOM data accordingly, and finally generate the product structure table;

[0125] Among them, the product BOM data is a list of all materials, components, and their assembly relationships included in the tire product. In the form of a hierarchical structure, it clearly shows the composition from the overall tire to each component, and then to more detailed components and raw materials.

[0126] In the product structure table, by using the product specifications, patterns, construction serial numbers, and finished product material numbers as indexes, the corresponding product material numbers can be selected and uploaded to the SAP system for data management.

[0127] By building with component modularization, the design process of tire semi-finished products is simplified, the design efficiency is improved, the tire semi-finished products are calculated and built according to the preset forming equipment parameters, the compatibility between the design and the actual production equipment is ensured, and a product structure table including the finished product material number and the green tire material number is generated, which is convenient for subsequent production and management.
