[0017] Figure 1 It is a flow chart of a preferred embodiment of the engineering instruction management method of the present application. DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the implementation of this application clearer, the technical scheme in the implementation of this application will be described in more detail in combination with the drawings in the implementation of this application. In the drawings, the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The described implementation is a part of the implementation of this application, not all of the implementations. The implementation described below with reference to the drawings is exemplary and is intended to be used to explain this application, and cannot be understood as a limitation on this application. Based on the implementation in this application, all other implementations obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. The implementation of this application is described in detail below in combination with the drawings.

[0019] The first aspect of the present application provides an engineering instruction management method, such as Figure 1 As shown, it mainly includes: Step S1, presenting a product feature tree with an engineering instruction template added to the user, wherein each node in the product feature tree is linked to at least one templated engineering instruction change order; Step S2: according to the node in the product feature tree selected by the design end user, the engineering instruction change order linked to the node is loaded into the editing interface of the design system, and the node attribute information of the node is added to the specified attribute of the engineering instruction change order; Step S3, obtaining the content of other attributes except the specified attributes in the engineering instruction change form filled in by the design end user on the editing interface of the design system, and generating a complete engineering instruction change form; Step S4, storing the product feature tree carrying the perfect engineering instruction change order in XML format and sending the stored XML format file to the manufacturing end; Step S5: extract the attribute content of the engineering instruction change order of the specified node in the product feature tree stored in XML format, convert it into a file format supported by the review platform, and conduct online review.

[0020] In step S1, the product feature tree is a key technology for characterizing the digital model design of aircraft products. The product feature tree provides a structured description of each system, component, part or assembly of the aircraft product in the form of a node. In order to highlight the core position of the product digital model and make the change content strongly associated with the digital model itself, and ultimately achieve the purpose of completely covering the change results with the digital model information and realizing the management of a unique data source, this application mounts at least one templated engineering instruction change order under each node of the product feature tree.

[0021] In some optional embodiments, in step S1, when the node of the product feature tree represents a product part or assembly, the node is linked to a templated engineering instruction change order; when the node of the product feature tree represents a product two-dimensional drawing, the node is linked to multiple templated engineering instruction change orders, each engineering instruction change order corresponds to a part or assembly of the product two-dimensional drawing.

[0022] It should be noted that when the nodes of the product feature tree represent the assemblies of the product, the engineering instruction change order is usually described in the assembly annotation model, and the two-dimensional product drawings usually include circuit diagrams, wiring diagrams, wiring harness diagrams, matching diagrams and some special parts or assemblies that are displayed in two-dimensional diagrams, such as insulation layers.

[0023] Step S1 is used to display the product structure tree to the user. After that, the user can click on the node in the product feature tree in step S2 to edit the engineering instruction change order mounted on the node. The editing process is completed in the editing interface of the design system. The design system here can be, for example, an online design and data management system (VPM). VPM and the data management system (PDM) that stores the product feature tree are integrated in advance so that the product feature tree stored in PDM and the contents of each node in the product feature tree can be read in a structured manner.

[0024] In step S2, when the design user selects a node, VPM reads the attribute information of the node and the engineering instruction change form of the node, and adds the attribute information of the node and some necessary template information to the engineering instruction change form, such as automatically generating a number, etc. After that, it is presented to the user in the form of an editable component so that the user can edit other unprocessed parts of the engineering instruction change form.

[0025] In some optional implementations, in step S2, adding the node attribute information of the node to the specified attribute of the engineering instruction change order includes: Add the name, model, and version of the node to the corresponding attributes of the engineering instruction change order.

[0026] It is understandable that the attributes of the engineering order change order also include name, model and version. Through the above method, these attributes of the engineering order change order are automatically filled in and are in an unchangeable gray state.

[0027] In some optional implementations, step S2 further includes: Step S21, read the attributes with optional preset values ​​in the engineering instruction change form, and display all the optional preset values ​​of the attribute in the form of a drop-down box on the editing interface of the design system for the design user to select, and display the attributes without optional preset values ​​in the form of a text editing box on the editing interface of the design system for the design user to fill in the content.

[0028] In this embodiment, in order to facilitate users to edit other unprocessed parts of the engineering instruction change form and ensure the standardization of the edited content, the value range of some attributes of the engineering instruction change form is limited. In some optional implementations, these attributes include the change category, the reason for the change, the change content, and the degree of impact on the products that have been manufactured before the change, etc. For example, the change category is a change to an existing product or a change to a non-existent product; the reason for the change is to improve the design, design improvement, coordination change, design error, process requirements, usage requirements or standard requirements, etc.; the degree of impact on the products that have been manufactured before the change is no impact, need to be reworked or repaired, or scrapped, etc.; the nature of the instruction is new, version change, number change, repair, special, version change, temporary change, series change, instruction revision or invalidation, etc., and the implementation status is whether it has been implemented or not.

[0029] In addition, there are some properties that need to be edited by the user, such as changing the content, the validity of the change, etc.

[0030] After the user completes editing on the VPM, it is stored in step S4. The engineering instruction change order is structured and stored along with the product feature tree, for example, in XML format, so that it can be easily circulated in other aircraft design systems, manufacturing systems or data management systems of other units. The data management system here can be, for example, a configuration management system, a prototype design system or an airborne equipment management system.

[0031] Finally, in step S5, the engineering instruction change order can also be reviewed and approved. This process is usually completed in a digital collaborative environment (DCE), and the DCE manages the review process, for example, by reflecting the review process through different statuses, including: Working: When the engineering instruction change order is successfully created but not submitted for review and approval, it is in the working state; Under review: When an engineering order change order is submitted for review along with a part or assembly and has not passed the approval process, it is in the under review state; Re-work: When the engineering instruction change order is rejected and returned to the designer during the review, it is in the re-work state; Approved: After approval, the engineering order change order becomes approved; Released: The status of the engineering instruction change order after it is successfully sent to the contractor / manufacturing unit is released; Voided: When the current engineering instruction change order is not applicable to any batch, the status can be set to Voided; Received: The status after the contractor or manufacturer successfully receives the data packet is the received status.

[0032] This application solves the problem of high frequency of changes caused by changes to the engineering instructions themselves when the content of the engineering instruction changes is inconsistent with the model content on the manufacturing side through structured design and management of engineering instruction changes, ensuring the consistency and controllability of data on the design and manufacturing sides, reducing design costs and risks, and shortening the development cycle.

[0033] The second aspect of the present application provides an engineering instruction management device corresponding to the above method, mainly comprising: A product feature tree loading module, used to present a product feature tree with an engineering instruction template added to the user, wherein each node in the product feature tree is linked to at least one templated engineering instruction change order; An engineering instruction change order loading module is used to load the engineering instruction change order linked to the node in the product feature tree selected by the design end user into the editing interface of the design system, and add the node attribute information of the node to the specified attribute of the engineering instruction change order; The engineering instruction change form modification module is used to obtain the content of other attributes other than the specified attributes in the engineering instruction change form filled in by the design end user on the editing interface of the design system, and generate a complete engineering instruction change form; A data storage and forwarding module, used for storing the product feature tree carrying the perfect engineering instruction change order in XML format and sending the stored XML format file to the manufacturing end; The review module is used to extract the attribute content of the engineering instruction change order of the specified node in the product feature tree stored in XML format, convert it into a file format supported by the review platform, and conduct online review.

[0034] In some optional embodiments, in the product feature tree loading module, when a node of the product feature tree represents a product part or assembly, the node is linked to a templated engineering instruction change order; when a node of the product feature tree represents a product two-dimensional drawing, the node is linked to multiple templated engineering instruction change orders, each engineering instruction change order corresponds to a part or assembly of the product two-dimensional drawing.

[0035] In some optional implementations, in the engineering instruction change order loading module, adding the node attribute information of the node to the specified attribute of the engineering instruction change order includes: Add the name, model, and version of the node to the corresponding attributes of the engineering instruction change order.

[0036] In some optional implementations, the engineering instruction change order loading module includes: An editing component generation unit is used to read an attribute with an optional preset value in the engineering instruction change order, and display all the optional preset values ​​of the attribute in the form of a drop-down box on the editing interface of the design system for selection by the design-end user; and display the attribute without an optional preset value in the form of a text edit box on the editing interface of the design system for the design-end user to fill in the content.

[0037] In some optional implementations, the attributes of the engineering instruction change order include at least the change category, the change reason, the change content, and the degree of impact on the products that have been manufactured before the change.

[0038] In some optional implementations, the degree of impact on products that have been manufactured before the change includes no impact, need for rework or repair, and scrapping.

[0039] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
