Description

Technical Field

[0001] The present application relates to the technical field of vehicle production and manufacturing, and specifically to a method and device for initializing a process route, verifying process trial production data, and reviewing a document. Background Art

[0002] The automotive manufacturing process is generally divided into three phases: trial production, preparation, and mass production. The trial production phase involves converting the product design blueprint into a prototype vehicle for regulatory, performance, and reliability verification. During product trial production, process attributes must be added to the product design data. For example, the manufacturing process flow (i.e., the process route) for assembled parts must be maintained. Process trial production data, which includes information such as assembly relationships, part types and quantities, process routes, and suppliers, serves as foundational data for production planning, parts procurement, logistics, workshop collaboration, and cost estimation. It is crucial to the quality, progress, and budget control of new product development projects. To ensure that the normal production of mass-produced models on the production line is not disrupted, the trial production data module operates relatively independently.

[0003] All vehicle components must be manufactured and assembled from raw materials according to a predetermined process plan, through a series of manufacturing and assembly steps, ultimately resulting in the final vehicle assembly. During this time, process routes ensure the smooth flow of manufacturing for over a thousand components. Because new product vehicles incorporate numerous newly designed assembly hierarchies and components, as well as the first-ever design applications of new materials and technologies, process design and maintenance also present numerous unique routing options for new assembly units. The number of components requiring process route maintenance can reach over a thousand, creating a complex and error-prone environment. Therefore, effectively initializing process routes, verifying and approving process trial production data, and verifying orders are pressing challenges. Summary of the Invention

[0004] The present application provides a method and device for process route initialization and process trial production data verification and order review, which can effectively realize the initialization of process route and the verification and order review of process trial production data.

[0005] In a first aspect, an embodiment of the present application provides a method for initializing a process route and verifying process trial production data and reviewing a document, the method comprising:

[0006] Obtain the vehicle logo, identification code, part number and assembly level of the whole vehicle. Based on the vehicle logo, identification code, part number information and combined with the assembly level, the flow sequence of parts is hierarchically classified to achieve automatic initialization of the process route of the vehicle parts.

[0007] Based on the vehicle identification code and combined with the parts number, the process route integrity, process route accuracy, pilot site compatibility, and data version consistency are verified to achieve automatic verification of process pilot data;

[0008] Integrate the scenario application of process trial production data verification into the structured data of process trial production data, create a functional module for reviewing the structured data of process trial production data, and realize automatic review of the structured data of process trial production data.

[0009] In conjunction with the first aspect, in one embodiment,

[0010] The vehicle logo is used to indicate the configuration and parameters of the vehicle model, and the parameters include parameters used to define the platform series to which the vehicle model belongs;

[0011] The identification code is a classification code for vehicle project data, which is used to classify the functions of product design and assembly units. The identification code is also used to identify whether the vehicle project data can be expanded, whether it is calculated in kind, and whether it is classified by function or by use.

[0012] The assembly level is used to identify the multi-process assembly flow of the entire vehicle, and each time the flow is completed, an assembly level is converted.

[0013] In conjunction with the first aspect, in one embodiment,

[0014] The process route is used to represent the manufacturing and assembly process of the vehicle body through the processes of rolling, punching, welding, coating, and assembly, from raw materials, blanks, parts to assembly, subassembly, chassis, and complete vehicle;

[0015] The production lines in the process route include the final assembly line, the cab interior line, the body painting line, the white body welding line, the frame painting line, the frame riveting line, the carriage production line, the rolling line, and the stamping line. Each production line corresponds to a different route code, and each component corresponds to a manufacturing route and an assembly route.

[0016] In conjunction with the first aspect, in one embodiment, the integrity of the process route is verified as follows:

[0017] When the verification item is the core assembly, process routes need to be maintained for the engine, gearbox, rear axle, frame, front axle, cab, instrument panel module, and cabin;

[0018] When the verification item is a component, the component under each component of the vehicle must maintain a process route;

[0019] When the verification item is an assembly or subassembly, if it is an external part and has a process route maintained, the process routes of its lower-level components need to be blocked and not included in the summary; if it does not have a process route maintained, its lower-level components need to have a process route maintained; if it is an internal part and has a process route maintained, its lower-level components need to have a process route maintained.

[0020] In conjunction with the first aspect, in one embodiment, the accuracy of the process route is verified as follows:

[0021] When the verification item is the in-house manufacturing route, if the component itself is an in-house part, its manufacturing route cannot be warehouse;

[0022] When the verification item is the supplier of in-house parts, if the parts themselves are in-house parts, the supplier must be listed;

[0023] When the verification item is the parent-child route correspondence, the assembly route of the child component must be consistent with the manufacturing route of the parent item.

[0024] In conjunction with the first aspect, in one embodiment, the verification of the compatibility of the pilot production site is as follows:

[0025] When the verification item is a production preparation part, the production preparation part route replacement is not allowed for the trial model;

[0026] When the verification item is supplier refresh, the trial-produced vehicle model and process route must correspond to the supplier;

[0027] When the verification item is a production preparation part, the trial model needs to replace the production preparation part route.

[0028] In conjunction with the first aspect, in one implementation, the verification of data version consistency is specifically:

[0029] The process trial production data must be consistent with the latest version of E-BOM.

[0030] In conjunction with the first aspect, in one embodiment, the scenario application of process trial production data verification is integrated into the structured data of the process trial production data, and a functional module for verifying the structured data of the process trial production data is created to realize automatic verification of the structured data of the process trial production data, specifically including:

[0031] Integrate the scenario application of process trial production data verification into the structured data of process trial production data, and create a functional module for verifying the structured data of process trial production data;

[0032] Use vehicle model as index, associate process trial production notice, and write the structured data path of process trial production data;

[0033] Jump to the trial production database, select the relevant vehicle model, start the functional module and output the verification result, review the structured data of the process trial production data based on the path jump method, and realize automatic order review.

[0034] In combination with the first aspect, in one embodiment, in the trial production database, all process trial production data can be searched by vehicle model.

[0035] In a second aspect, an embodiment of the present application provides a device for initializing a process route, verifying process trial production data, and reviewing a document. The device includes:

[0036] An initialization unit, which is used to obtain the vehicle logo, identification code, part number and assembly level of the vehicle, and based on the vehicle logo, identification code, part number information and combined with the assembly level, classify the flow sequence of parts in layers to achieve automatic initialization of the process route of the vehicle parts;

[0037] The verification unit is used to verify the process route integrity, process route accuracy, pilot site compatibility, and data version consistency based on the vehicle identification code and part number, thereby realizing automatic verification of process pilot data;

[0038] The document review unit is used to integrate the scenario application of process trial production data verification into the structured data of process trial production data, create a functional module for reviewing the structured data of process trial production data, and realize automatic review of the structured data of process trial production data.

[0039] The beneficial effects of the technical solutions provided in the embodiments of the present application include:

[0040] By constructing a digital model of process route initialization, process trial production data verification, and structured data review of process trial production data, it can be promoted and applied to various process flow scenarios in the manufacturing industry, reducing the workload of manual identification and judgment of content and improving efficiency; process route initialization can reduce a large amount of manual maintenance workload, improve work efficiency, and avoid the risk of manual miswriting; the application of process trial production data verification function can effectively avoid errors and omissions in the variety and quantity of installed parts, avoid the risks of physical waste of parts, missing parts during installation, project schedule delays, and improve the accuracy of design verification.

[0043] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] First, some technical terms in this application are explained to facilitate those skilled in the art to understand this application.

[0045] ET Trial: Engineering Trial, during the product development phase, a prototype is designed and manufactured to verify the correctness of the design and the feasibility of the assembly process, and to conduct physical verification of the product design.

[0046] Process route: The manufacturing and assembly process of parts before they are loaded onto vehicles is divided into manufacturing route and assembly route.

[0047] Process trial production data: Add professional process flow routes to the structured BOM (Bill of Materials) design for product trial production and installation, generating data that can be applied to planning and production.

[0048] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0049] First, the embodiment of the present application provides a method for process route initialization, process trial production data verification, and order review, which can realize process route initialization, process trial production data verification, and order review of structured data of process trial production data by digital means during the process maintenance of product trial production data. Specifically, the process route is initialized first, and then the process trial production data is maintained and verified. If the verification fails, it is modified. If the verification passes, the structured data is loaded and then verified. After the verification passes, the order review is released. The scenarios in which the released structured data of process trial production data is applied include the order planning SCF system, the shipping and settlement SAP system, the trial production technology management system, and the prototype vehicle review QMS system.

[0050] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of the process route initialization, process trial production data verification and order review method for this application. Figure 1 As shown, the process route initialization and process trial production data verification and document review methods include:

[0051] S1: Obtain the vehicle logo, identification code, part number and assembly level of the whole vehicle. Based on the vehicle logo, identification code, part number information and the assembly level, classify the flow sequence of parts in layers to achieve automatic initialization of the process route of the vehicle parts.

[0052] S2: Based on the vehicle identification code and combined with the part number, the process route integrity, process route accuracy, pilot site compatibility, and data version consistency are verified to achieve automatic verification of process pilot data;

[0053] S3: Integrate the scenario application of process trial production data verification into the structured data of process trial production data, create a functional module for reviewing the structured data of process trial production data, and realize automatic review of the structured data of process trial production data.

[0054] Specifically, the initialization of the process route is first explained.

[0055] All vehicle components must be manufactured and assembled from raw materials according to a defined process plan, through a series of manufacturing and assembly steps, ultimately completing the vehicle. During this process, process routing ensures the manufacturing flow of over a thousand components. Because new product vehicles incorporate numerous newly designed assembly hierarchies and components, as well as the first-ever design applications of new materials and technologies, process design and maintenance also presents numerous unique routing options for new assembly units. The number of components requiring process routing maintenance can reach over a thousand, creating a complex and error-prone process.

[0056] Therefore, to ensure that all parts for vehicle assembly are purchased, produced, and transferred between processes in an orderly manner according to process planning and process sequence, a process route is essential to guide on-site physical flow, forming a systematic project. A multi-dimensional analysis of the process trial production and maintenance process is conducted to ensure the completeness, correctness, compatibility, and consistency of product data updates. This allows conventional production process route maintenance to be structured to automatically assign and initialize routes. This automated route initialization reduces manual maintenance workload by at least half, significantly improving work efficiency.

[0057] It should be noted that the process route is used to represent the flow of physical objects loaded on the vehicle through the processes of rolling, punching, welding, painting, and assembly, from raw materials, blanks, parts to assembly, assembly, chassis, and complete vehicles; according to the correspondence between the assembly of parts layer by layer in the data structure and the welding, painting, and final assembly production lines, the initialization route is calculated and deployed using the identification code, part number characteristics, and structure expansion level.

[0058] The production lines in the process route include the final assembly line, cab interior decoration line, body painting line, body-in-white welding line, frame painting line, frame riveting line, carriage production line (bottom / side / rear / front punch welding and painting), rolling line, and stamping line. Each production line corresponds to a different route code, and each component has a corresponding manufacturing route (where it comes from) and assembly route (where it goes).

[0059] The following is an explanation of the corresponding meanings of the codes for the main process routes in conjunction with Table 1.

[0060] Table 1

[0061] Process routing code Abbreviation Interpretation CK storehouse For purchased parts, suppliers deliver them to designated distribution warehouses ZP assembly Chassis assembly line NS Interior Production line for assembling interior parts from painted body shells YQ paint Cab shell base paint production line HZ Welding Cab shell and parts welding production line JQ Paint rack Frame primer coating line CJ frame Frame welding and riveting assembly line CX car Various carriage assembly production workshops, including punching, welding and painting processes

[0062] Furthermore, regarding the vehicle logo, identification code, part number, and assembly level, the vehicle logo is used to indicate the configuration and parameters of the vehicle model, and the parameters include parameters for defining the platform series to which the vehicle model belongs, and for distinguishing whether the current vehicle model belongs to the light truck or light passenger category; different vehicle categories have different product structures, different process manufacturing solutions, and different ways of expressing process routes.

[0063] The identification code is a classification code for vehicle project data, used to categorize the functions of product design assembly units. It also identifies whether vehicle project data can be expanded, whether it can be calculated as physical items, and whether it is categorized by function or by use. A vehicle model's structure tree contains various forms of assembly data, including parts, standard components, assemblies, functional components, process components, combination blocks, and devices. Blocks and devices are virtual, non-physical assembly units that do not require process routing maintenance. Incorrectly maintaining process routing can cause confusion in procurement and production. However, expansion is necessary to locate the next-level components using non-physical assembly units.

[0064] The meanings of the main identification codes are explained below in conjunction with Table 2.

[0065] Table 2

[0066]

[0067]

[0068] Part numbers are established in accordance with relevant part numbering standards. The first four digits of a part number represent the automotive product system classification number. The first two digits are the group number, such as 10 for the engine system, 17 for the transmission system, and 12 for the exhaust system. The third and fourth digits are the subgroup number, such as 1040 for the engine accessory group, 1703 for the transmission control system, 1203 for the muffler intake system, and 1204 for the exhaust insulation system. Parts or part families can be identified by capturing part number features. For example, the part number for the cab assembly on all light truck models begins with 5000012, and the wheel assembly begins with 3101A.

[0069] Assembly levels are used to identify the multi-step assembly process of a complete vehicle, with each level transitioning. A complete vehicle consists of over a thousand different parts, progressing from parts to assembly, chassis, and finally the complete vehicle, all through multiple assembly processes, with each transition transitioning to a new assembly level. For example, the frame rail, left rail, and right rail components form a rail block. This rail block is riveted together with other related components to form the unpainted frame assembly. This then passes through the painting line to become the painted assembly, and then to the final assembly line where it is assembled with other parts to form the complete vehicle. For example, if we take the complete vehicle as the top-level assembly unit and expand downward, the first level is the painted frame assembly, the second level is the unpainted frame assembly, the third level is the rail block, and the fourth level is the frame rail. This allows for layer-by-layer tracing back to the frame rail component. In other words, each assembly can be expanded downwards to the component, and each component and assembly can be traced back upwards to the complete vehicle. For a certain hierarchical item, the hierarchical items that expand downward are child items, and the hierarchical items that return upward are parent items.

[0070] When initializing the process route, the vehicle logo, identification code, and assembly level of the vehicle product data are read, and combined with the characteristics of the process route, classification rules are extracted, integrated, and converted into a recognizable process route plan, thereby realizing automatic initialization of the process route.

[0071] The following examples illustrate this.

[0072] First, read the vehicle logo to determine whether it is a light truck or a light passenger, and select the corresponding process route maintenance plan. Take a light truck as an example:

[0073] (1) When the vehicle is unfolded, the identification code 40 is a block. The block itself is a virtual assembly unit and the process route is not initialized. The next level process route of the block is initialized to CK-ZP. There are special cases:

[0074] a. If the block starts with 3101A (wheel assembly, virtual in-house manufacturing), the next level process route is initialized to ZP-ZP;

[0075] b. If the group block starts with 3550, 3515B, 3533B, or 3543A, the next level identification code of the group block is "56", which is a process assembly, and the process route is not initialized;

[0076] c. If the block starts with 3904A, its lower-level components may be stocked as materials and auxiliary materials, and the process route will not be initialized;

[0077] (2) Major assemblies under the complete vehicle: those with identification codes starting with “3” (functional combination blocks) and part numbers starting with “1000, 1700, 2400, 3000” (engine, gearbox, rear axle, front axle), purchased from suppliers, with the process route initialized as CK-ZP;

[0078] (3) Carriage: The carriage assembly is produced separately in the carriage workshop and the chassis is shipped from the final assembly workshop to the carriage workshop for unloading, so the process routes of various carriage assemblies are initialized as CX-CX;

[0079] (4) Cab: Part numbers starting with 5000012:

[0080] ① If the expanded data contains a part number starting with 5000007- (cab technical agreement), it means the cab is a purchased part. In this case, the process route is initialized to CK-ZP and no further expansion or initialization is performed.

[0081] ② If there is no part number starting with 5000007- in the expanded data, it means the cab is a self-made part. In this case, the process route is initialized to NS-ZP and the expansion continues.

[0082] (5) In the next level of data where the parts start with 5000012 and continue to expand downwards:

[0083] ① The next level process route of the block (identification code 40) is initialized to CK-NS;

[0084] ② The process route is not initialized for the combination block whose identification code starts with 3. For example, the 35G1A cab brake system combination block is a collection of blocks and should not have a process route. The process route of the next-level part expanded from its lower-level block is initialized to CK-NS.

[0085] ③Special instrument panel module with an electrical component whose identification code begins with 3 and whose part number begins with 53G1A. This is a pre-assembled assembly of an instrument panel workbench and electrical components purchased from a supplier. The process route is initialized as CK-NS.

[0086] ④ Parts starting with 5000014 are sent to the interior trim line for assembly after painting, and their process route is initialized to YQ-NS;

[0087] (6) In the next level of data expanded downwards for parts starting with 5000014:

[0088] ① The process route of the next level of the block (identification code 40) is initialized to CK-YQ;

[0089] ②For parts starting with 5000016, the process route is initialized to HZ-YQ;

[0090] (7) 5000016 is expanded to the next level, and the process route of the parts starting with 5000020 is initialized to HZ-HZ.

[0091] To summarize, by expanding step by step, we extract identification codes, part numbers, and special component features, combine assembly levels and logical associations, and reconstruct rules for hierarchical classification of component flow sequences to assign initial process routes to vehicle components.

[0092] The following table 3 summarizes the process routes.

[0093] Table 3

[0095]

[0096] Specifically, the verification of process trial production data will be described in detail.

[0097] New product trials involve the application of new structures, processes, materials, and methods, necessitating a high degree of technological exploration and prone to logical errors such as misjudgment of the path forward. Process trial data is fundamental and is shared across multiple systems, including procurement, planning, material handling, quality, and settlement. This data flow, from data to physical material flow, impacts R&D expenses and project progress. Therefore, the accuracy of this data, encompassing the content of process maintenance, must be verified before release.

[0098] Utilize product identification codes to identify modules, components, assemblies, and device diagrams, distinguish between virtual and real objects, consider manual errors and omissions in the maintenance of process trial production data, and differences in route processing in different trial production scenarios, and verify the integrity, accuracy, compatibility, and consistency of the entire process trial production data for trial production and installation, thus building a digital verification function.

[0099] The maintenance of process trial production data mainly includes five aspects: trial production position, manufacturing route / assembly route, definition of internal parts / external parts, suppliers, and data structure update. That is, these five aspects of process maintenance content are verified to verify whether they exist, are correct, and match.

[0100] The basic idea of verification is:

[0101] To determine whether process trial production data should be maintained with a process route, it is necessary to identify at the assembly level whether the data is a virtual block or a physical part / assembly. This means identifying the classification of the project data. Special parts / assemblies also require the combination of part number features. Therefore, the "identification code + part feature number + assembly level expansion" method is used to identify the physical object and check whether any process routes are missed.

[0102] Physical parts / assemblies with process routes to see if there are suppliers;

[0103] The in-house and out-house manufacturing route must correspond to the supplier's in-house and out-house manufacturing. The manufacturing route CK (coordination warehouse) means that the supplier delivers parts to the coordinating warehouse, and then transfers them from the coordinating warehouse for assembly. Therefore, parts with the manufacturing route CK are outsourced purchased parts. Only supplier codes R8812 and R8813 are in-house suppliers; all others are outsourced suppliers.

[0104] The manufacturing process route (where it comes from) and the assembly route (where it goes) are used. Components are assembled layer by layer, so the assembly route of the child item corresponds to the manufacturing route of the parent item and matches each other.

[0105] For pilot production in the pilot workshop of the R&D institute, the pilot production department will independently issue pilot production plans and orders for production preparation parts (non-mass production parts) used in new models. Therefore, the manufacturing route of outsourced production preparation parts must be replaced by the R&D route.

[0106] Product data is continuously improved and updated, so before releasing process trial production data, it is necessary to compare it with the latest product E-BOM data to see if there are any structural updates.

[0107] It can be seen that the process trial production data verification uses the identification code combined with the part number to drive the judgment of the process route, uses the manufacturing route and the supplier to verify the matching of internal and external production, uses the relationship between parent items and child items, manufacturing routes and assembly routes to verify the matching, and uses the relationship between trial production positions and R&D route replacements to verify the matching, so as to maintain the consistency of data and the latest product E-BOM verification version.

[0108] Furthermore, for the verification of process route integrity, specifically:

[0109] When the verification item is the core assembly, process routes need to be maintained for the engine, gearbox, rear axle, frame, front axle, cab, instrument panel module, and cabin;

[0110] When the verification item is a component, the component under each component of the vehicle must maintain a process route;

[0111] When the verification item is an assembly or subassembly, if it is an external part and has a process route maintained, the process routes of its lower-level components need to be blocked and not included in the summary; if it does not have a process route maintained, its lower-level components need to have a process route maintained; if it is an internal part and has a process route maintained, its lower-level components need to have a process route maintained.

[0112] Furthermore, for the verification of the accuracy of the process route, specifically:

[0113] When the verification item is the in-house manufacturing route, if the component itself is an in-house part, its manufacturing route cannot be warehouse;

[0114] When the verification item is the supplier of in-house parts, if the parts themselves are in-house parts, the supplier must be listed;

[0115] When the verification item is the parent-child route correspondence, the assembly route of the child component must be consistent with the manufacturing route of the parent item.

[0116] Furthermore, for the verification of the supporting facilities of the trial production site, specifically:

[0117] When the verification item is a production preparation part, the production preparation part route replacement is not allowed for the trial model;

[0118] When the verification item is supplier refresh, the trial-produced vehicle model and process route must correspond to the supplier;

[0119] When the verification item is a production preparation part, the trial model needs to replace the production preparation part route.

[0120] Furthermore, for the verification of data version consistency, specifically:

[0121] The process trial production data must be consistent with the latest version of E-BOM.

[0122] Specifically, the review of process trial production data is explained in detail at the end.

[0123] In this application, the scenario application of process trial data verification is integrated into the structured data of process trial data, and a functional module for reviewing the structured data of process trial data is created to realize automatic review of the structured data of process trial data, specifically including:

[0124] S301: Integrate the scenario application of process trial production data verification into the structured data of the process trial production data, and create a functional module for verifying the structured data of the process trial production data;

[0125] That is, based on the above-mentioned process trial production data verification, the verification scenario application is integrated into the structured data of the process trial production data to build an automatic order review function for structured data;

[0126] S302: Using the vehicle model as an index, associate the process trial production notice and write the structured data path of the process trial production data; in the trial production database, all process trial production data can be searched by vehicle model;

[0127] S303: Jump to the trial production database, select the relevant vehicle model, start the functional module and output the verification result, review the structured data of the process trial production data based on the path jump method, and realize automatic order review.

[0128] The process route initialization and process trial production data verification and order review method of the embodiment of the application:

[0129] (1) Replace most manual maintenance of process routes with digital means, and realize the orderly planning of procurement, production organization, and inter-process transfer of all parts for loading according to process planning and process sequence. Guide the on-site physical flow based on the process route to form a systematic project, and build the process route maintenance of conventional production into an automatically assigned initialization route, which greatly improves work efficiency;

[0130] (2) Replace manual data verification with digital means. New product trial production involves the application of new structures, new processes, new materials, new methods, etc., which is highly exploratory in technology and prone to logical errors in route misjudgment. Process trial production data is basic data and will be passed to multiple systems such as procurement, planning, material drawing, quality, and settlement for use, affecting R&D costs and project progress. Therefore, before the process trial production data is released, the content of process maintenance needs to be verified. The process trial production data verification uses the identification code combined with the part feature number to drive the judgment of the process route. Considering the manual errors and omissions in the data maintenance process, as well as the differences in route processing in different trial production scenarios, the process trial production data of the trial production and loading are verified for integrity, accuracy, compatibility, and consistency as a whole, and a digital verification function is constructed;

[0131] (3) Use digital means to assist manual approval. On the basis of process trial production data verification, integrate the verification scenario application into the structured data of process trial production data to build an automatic review function that can carry structured data.

[0132] This application analyzes the relationship between the algorithm for maintaining process routes, virtual and physical, internal and external, parent-item and child-item manufacturing routes and assembly routes, etc., and takes into account the human error points in the data maintenance process, as well as the differences in route processing in different trial production scenarios, and designs a targeted verification calculation method to realize automatic data verification, thereby realizing automatic order review. Create a process route measurement method, establish rules for identifying component manufacturing and assembly process routes from a system recognition perspective, and use digital means to initialize and assign values to component process routes, reducing a large amount of manual maintenance workload and improving work efficiency; create an error-proof verification calculation method for process trial production data maintenance, establish data verification content and condition compliance judgment rules, establish a logical method for data verification calculation, and use digital means to realize data verification; the approval document carries structured data, reconstructs the data scenario, combines verification, integrates the judgment and review process into the automation rules, and integrates content and form. During approval, verification can automatically identify whether the data has passed, realizing online synchronous verification and review, and realizing automatic order review.
