A method and a system for controlling product data transmission based on an information system according to an embodiment of the present application will be described with reference to the accompanying drawings. First, a product data transmission control method based on an information system proposed according to an embodiment of the present application will be described with reference to the accompanying drawings.

Fig. 1 is a flowchart of a product data transmission control method based on an information system according to an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:

step 101, connecting the structure trees in multiple stages of product development, and communicating a function baseline, a distribution baseline and a product baseline in the technical state management of the product, wherein the multiple stages comprise a design stage, a process stage and a manufacturing stage, the structure trees are distributed in multiple information systems corresponding to the product, and the multiple information systems comprise a product data management system, an enterprise resource management system and a manufacturing execution system.

The multiple stages may include various links such as design, process, production preparation, manufacturing, plan management and the like in the product development process, the structure trees in the various stages related to product data transmission may be connected in the application, and the specific related stages are not limited herein.

It should be noted that, in the product development process, the data at each stage in the design, process, manufacturing and other links are correspondingly dispersed in a plurality of information systems such as a product data management system, an enterprise resource management system, a manufacturing execution system and the like, and the system in which the data at each stage is located is usually fixed, for example, the related data at the manufacturing stage is located in the manufacturing execution system, so that, based on the data transmission path between the systems such as the product data management system, the enterprise resource management system, the manufacturing execution system and the like opened in this step, when the data at each stage from the design stage to the process stage and then to the product manufacturing stage is subjected to transmission control, the automatic transmission of the data in each system between the corresponding information systems according to the technical state management idea is realized.

Continuing with the above description, where the structure tree is a data model describing the data structure in a tree-like manner, in the embodiment of the present application, the structure tree in each stage may include: three-dimensional design models, bill of Material (bom) trees of various types, process structure trees, production plan trees, and so on. The technical state of a product refers to the physical and functional characteristics specified in the technical documentation that are achieved in the product, while the technical state management of a product refers to the application of various types of means, such as technical and administrative management, to perform various types of management activities on the technical state of the product, including identification, control, auditing and remembering, etc. The base line in the technical state management is an initial plan formed by any configuration item after the configuration item passes through formal review and enters a controlled state at different time points of product development, for example, the distribution base line refers to a requirement specification which is formally reviewed and approved at the end of a requirement analysis stage, namely the distribution base line is an initially approved distribution configuration identifier.

In the embodiment of the application, related structure trees distributed in each stage in each information system corresponding to a product are connected in series in different forms, and then an implementation bom tree and an implementation route tree generated in the manufacturing process are added, so that the connection of the structure trees in a plurality of stages is realized, and the whole process from a function baseline to a distribution baseline and then to a product baseline in the technical state management is completed.

Therefore, by combining the subsequent data transmission control method, the data transmission path among the systems such as the product data management system, the enterprise resource management system, the manufacturing execution system and the like can be opened, and the automatic transmission of the data among the systems based on the transmission path can be conveniently realized

As an example, in order to more clearly describe a specific implementation process of the present application for implementing the connection of the structure trees and the communication of the base lines, a specific method for concatenating the structure trees in multiple stages of product development provided in the embodiment of the present application in different forms is described below, and fig. 2 is a schematic flow chart of the specific method for concatenating the structure trees in multiple stages of product development provided in the embodiment of the present application in different forms, as shown in fig. 2, the method includes the following steps:

step 201, designing a three-dimensional model of the product to generate a three-dimensional model tree of the product.

Specifically, a product three-dimensional model is designed in a product data management system through design application, for example, CAD software, and after the design is completed, a three-dimensional model tree of the product, that is, an Engineering bill of materials (EBOM) of the structure of the product, is automatically generated in the product data management system.

And 202, after supplementing the non-drawing parts and the main data attributes in the three-dimensional model tree, carrying out design file examination and signing to generate a design bill of materials DBOM of the product.

The non-drawing component is a component without a view of parts, such as auxiliary materials, and the main data attribute may be a related attribute of main data applied by a user in the main data system.

Specifically, in this embodiment, after the three-dimensional model tree is supplemented with the non-image parts such as the auxiliary materials, the related attributes of the main data applied in the main data system are supplemented, the Design document approval process is initiated, the Design manufacturability review is performed by the related personnel such as the process personnel, and after the process meeting is completed, the Design bill of materials (Design BoM, DBOM for short) of the product is formed through approval.

Step 203, compiling a process bill of materials (PBOM), determining process routes and material information of parts of the product, and initiating a process route and material rating approval process.

Specifically, after the Process is qualified, a Process bill of materials (Process BoM, PBOM for short) may be compiled, and information such as a Process route and materials of the component may be determined, for example, the determined information may specifically include: the method comprises the steps of self-making outsourcing, whether the materials are fed internally, a main pipe unit, a main manufacturing unit, blank types, outsourcing or outsourcing manufacturers of blanks, blanking sizes, the number of the producible products, single-piece process quota and the like.

And, after the product design approval process in step 202 is completed, a process route and material rating approval process may be initiated.

In an embodiment of the present application, after the PBOM is controlled, the PBOM can be synchronized to the enterprise resource management system and the manufacturing execution system, and the determined material information and the structure of the PBOM are synchronized to the enterprise resource management system and the manufacturing execution system.

Step 204, planning a manufacturing process route, allocating manufacturing resources, and compiling a structuring process used by the manufacturing execution system.

Specifically, after the process route and the material rating approval are completed, a manufacturing process route can be planned, resources can be reallocated, and a check point can be set. Then, the structured process used by the manufacturing execution system is programmed according to preset programming criteria and methods, for example, the process available for the downstream manufacturing execution system is programmed according to the structured process programming method according to the principle of one step, one figure, one card and one inspection. Wherein, the structured process of weaving can include but is not limited to: the method comprises the following steps of procedure lines, operation steps, process drawings, detection parameters, check points, loading part distribution, process resource distribution and the like, so that a process structure tree is generated by a structural drawing compiling method and is issued to a manufacturing execution system along with a structured process.

And step 205, combining the process sent by the product data management system and the production order sent by the enterprise resource management system to produce the product, and summarizing the production and processing information of the product after the production is finished so as to generate a bill of material (BOM) for the product.

Specifically, the process issued by the received product data management system and the production order issued by the enterprise resource management system are bound in the manufacturing execution system, and the product production is started. After production is finished, according to actual generation operation, information of actual production and processing of the product is summarized to form the actual BOM of the product.

Therefore, the method carries out subsequent structure tree compiling in other related systems based on the structure tree generated in one system, realizes the series connection of different forms of the structure tree, and connects the structure trees in a plurality of stages. Through data synchronization and transmission among all information systems, the whole process communication of a function baseline, a distribution baseline and a product baseline in technical state management is realized. Therefore, the data transmission paths among the systems such as a product data management system, an enterprise resource management system, a manufacturing execution system and the like can be opened, and the subsequent data transmission is facilitated.

Step 102, uniformly managing the design information and the process information of the product through a product data management system, and automatically transmitting the design information of the product from a design stage to a process stage in a forward direction.

Specifically, the design information and the process information of the product are managed in a unified manner by the product data management system, for example, by setting a data structure corresponding to the design information and the process information in a preset standard format, and when the design information of the product is transmitted from the design stage to the process stage, the process rules can seamlessly and directly refer to the product design information.

In one embodiment of the present application, automatically forwarding design information for a product from a design stage to a process stage includes directly referencing the design information for the product in a process recipe after generating design information that meets a standard in a product data management system. In this example, the design information of the products collectively managed by the product data management system includes: the design model, drawing information, basic information of the part components, replacement information of the part components, state information of the part components and a product matching list.

In particular, the process rules are process files determined by words, diagrams or other carriers for instructing product processing and worker operation, and in this embodiment, the process rules can be seamlessly and directly cited by the following contents, but are not limited to the following contents: designing model and drawing information, wherein the model and the drawing information can specifically comprise an NX three-dimensional model, a two-dimensional drawing, a lightweight model and the like of a product; the basic information of the part components can specifically comprise product codes, pattern codes, main data codes, names, weight-related components, materials and the like; the replacement information of the part component specifically refers to the relationship between the replacement components of the part components provided by different suppliers; the product matching detail list can specifically comprise components, standard components, auxiliary materials and the like; the component state information may specifically include a version number, an owner, a phase flag, a controlled state, and the like.

Therefore, design and process information are uniformly managed by the product data management system, so that the process rules can seamlessly and directly reference the product design information, and forward transmission of technical states from a design stage to a process stage is realized.

Step 103, integrating the process procedures of the product data management system and the manufacturing execution system, and automatically transmitting the process information of the product from the process stage to the manufacturing stage in a forward direction.

In the embodiment of the present application, as a possible implementation manner, the process rule integration setting of the product data management system and the manufacturing execution system includes but is not limited to: rated working hour information of working procedures or working steps, working procedure routes, working procedure characteristics, working procedure contents, process parameters, loading pieces, process auxiliary materials, resource information, editing records, material rating information, process accessories and inspection points.

Specifically, the process route includes information such as general processes, special process processes, process serial-parallel, process execution conditions, and process basic information, wherein the process basic information may include a charge unit, a process name, and process contents. The process characteristics refer to information such as key processes and special processes. The process content refers to operation content, reference process/process content and reference general process content information. The process parameters refer to detection content and parameter name information. The loading component refers to the process master material information such as the design component, the standard component, and the design auxiliary material of the component from the EBOM generated in step 101. The process auxiliary material is auxiliary material used in process design. The resource information refers to resource information related to tools, such as equipment, measuring tools, cutters and the like. A scratch record, i.e., a value-structured process change record. Material rating information, i.e. information for determining the material usage, such as the blanking size of the part, the number of producible parts, and the process rating of a single part. The process accessories comprise accessory information such as process drawings, process attached sheets and the like. The check points are information such as special check points and military check points in the process design. The process or step rated man-hour information is rated man-hour information required for performing each process or step operation in the process.

In the embodiment of the application, the manufacturing execution system can receive the transmitted structured process of the product data management system by integrating the process procedures of the product data management system and the manufacturing execution system, and the automatic transmission of the process data between the data product data management system and the manufacturing execution system is realized.

Further, after the manufacturing execution system receives the process data, the subsequent manufacturing production can be performed according to the received process data. As a possible implementation manner, in an embodiment of the present application, after the process information of the product is automatically transmitted from the process stage to the manufacturing stage, the manufacturing execution system may be further controlled to receive the structural process information transmitted by the product data management system, perform plan binding and production dispatching according to the structural process information, and start manufacturing.

In order to improve the accuracy of the process information transmission between the product data management system and the manufacturing execution system, in one embodiment of the present application, when the product data management system transmits the process information from the process stage to the manufacturing execution system for the first time, the method includes the steps of first controlling the product data management system to set the rated labor hour information of the process or the process step to be null, that is, to leave null at the rated labor hour information of the process/the process step, and then supplementing the rated labor hour information in the manufacturing execution system according to the actual operation, for example, a workshop manufacturer supplements the rated labor hour information when performing the operation, reversely transmits the rated labor hour information to the product data management system, and finally supplements the corresponding rated labor hour information determined actually at the process or the process step position of the product data management system.

Therefore, through the integration of the process procedures of the product data management system and the manufacturing execution system, the data transmission control from the process stage to the product manufacturing stage is realized, and the process data is automatically transmitted between the product data management system and the manufacturing execution system according to the technical state management thought.

To sum up, in the product data transmission control method based on the information system according to the embodiment of the present application, the structure trees in the multiple stages of product development are connected to communicate the function baseline, the distribution baseline, and the product baseline in the technical state management of the product, then the design information and the process information of the product are uniformly managed by the product data management system, the design information of the product is automatically forward transmitted from the design stage to the process stage, the process procedures of the product data management system and the manufacturing execution system are integrated, and the process information of the product is automatically forward transmitted from the process stage to the manufacturing stage. Therefore, the method establishes the data transmission path between the information systems corresponding to the product, automatically transmits the data in the information systems according to the technical state management idea, is beneficial to establishing a unified information design and manufacture integrated platform, realizes the automatic transmission of the data between the systems in the design and manufacture integrated platform, and ensures the consistency and the accuracy of the data scattered among the systems at different stages and improves the efficiency of data transmission by carrying out transmission control on the data from the design stage to the process stage and then to the product manufacture stage.
