Description

Technical Field

[0001] This invention relates to the field of simulation testing technology, and in particular to a test point coordination system and method for civil aircraft testing. Background Technology

[0002] Because of the complexity of the overall structure of civil aircraft, the manufacturing process often involves the cooperation of multiple departments and individuals. Among them, flight test modification design (the process of adjusting the aircraft structure, electronic systems, or testing equipment to verify performance, optimize design, or meet specific testing requirements) is an essential part of the civil aircraft production process. The production of civil aircraft requires the collaboration of multiple departments to carry out flight test modification design work.

[0003] In the existing technology, flight test modification design is a secondary development design based on the existing aircraft body digital model (digital model refers to a three-dimensional geometric model, i.e., 3D Geometric Model).

[0004] The specific process of flight test modification design is as follows: Based on the timely iterative full-aircraft digital model (i.e., the simulation model of the entire aircraft), various specialties within the civil aircraft design department propose flight test tasks and generate a document specifying the target parameters for testing in tabular form (this document, referred to as a parameter document in this text for ease of explanation, specifies the content that needs to be tested on the full-aircraft model). This document is then passed to the Flight Test Engineering Department, which breaks down, integrates, and organizes it to create task allocation rules based on the number of flight tests, subjects, and functions of each flight test modification department. This results in corresponding task allocation documents, which are then transmitted to the relevant flight test modification departments. Each flight test and modification department performs testing and installation tasks according to the received task allocation documents. Simultaneously, they provide a description of the equipment installation status corresponding to each task to the relevant professionals in the civil aircraft design department for review. The civil aircraft design department then determines whether the description of the equipment installation status provided by the flight test and modification department meets the requirements. If not, a new flight test task is assigned to the unsatisfactory parts for iterative processing until the civil aircraft design department is satisfied with the received description of the equipment installation status, thus completing the flight test and modification design process. Once the flight test and modification design process is completed, subsequent testing operations on the aircraft model (i.e., the full-scale digital model) are performed.

[0005] During the above-mentioned flight test and modification design process, the documents exchanged between the civil aircraft design department, flight test engineering department, and flight test and modification department—including documents specifying test target parameters, task allocation documents, and equipment installation descriptions—are all presented and transmitted in text-based format. Therefore, while it is possible to transmit requirement or operational target description documents during civil aircraft flight test and modification design, it is difficult for the recipients to intuitively understand the specific requirements. Specifically, the target of the flight test modification design is actually a very complex mechanical device. Using existing technology that only describes the target object (or the object to be operated) in words is extremely unintuitive. For example, the description of the target object in the specified test target parameter document might be in the form of parameters or labels. After receiving such data, the flight test modification department needs to compare and search the corresponding parameter table to understand the approximate location of the part to be tested in the aircraft's digital model. This is because the parameter documents provided by civil aircraft design departments in the existing technology only indicate the approximate location, without providing specific coordinates. For example, it might only state that it is on the wing, but not the specific coordinate position on the wing (in fact, even if coordinates are given in a document that only provides textual descriptions, the specific coordinate position cannot be determined manually). However, with a large amount of this type of data, determining the part to be tested is time-consuming and very prone to errors. The documents received by the civil aircraft design department regarding equipment installation are also presented in textual descriptions. Therefore, it is difficult for the civil aircraft design department to understand the actual equipment installation to be implemented by the flight test and modification department from such documents. For example, when there is a deviation between the test location understood by the flight test and modification department and the test location actually required by the civil aircraft design department, the test location described in the equipment installation description document fed back to the civil aircraft design department may still be consistent with the description in the document specifying the test target parameters. This makes it easy for the civil aircraft design department to overlook possible errors in the equipment installation, which in turn makes it difficult to troubleshoot the cause of the failure later.

[0006] The design of test flights and modifications for civil aircraft is characterized by multi-departmental collaboration, mutual cooperation, and iterative iteration. However, current technologies for civil aircraft test modification design rely on document transmission with textual descriptions to execute all information transfer processes. For the test flight requirements proposed by the design department (i.e., the civil aircraft design department, which will be referred to as "design" for simplicity), the test modification department (i.e., the test flight and modification department, which will be referred to as "test modification" for simplicity) can only analyze and design based on documents (i.e., documents specifying the target parameters for testing). This lacks accurate three-dimensional data. Furthermore, whether the design results meet the test flight parameter requirements of the civil aircraft design department requires the designers (i.e., the personnel in the civil aircraft design department, which will be referred to as "designers" for simplicity) to rely on documents (i.e., documents describing the equipment installation status) for reverse evaluation. This data transmission method used to complete flight test modification design cannot guarantee the accuracy of measurement point data transmission, and lacks accurate three-dimensional spatial location information of measurement points and allowable installation range of equipment. For the full-scale flight test modification design of civil aircraft, frequent repeated confirmation, iteration and modification will consume a lot of energy and cannot guarantee accuracy, which is not conducive to the rapid, efficient and accurate progress of civil aircraft flight test modification work. Summary of the Invention

[0007] In view of the above-mentioned deficiencies of the prior art, the present invention proposes a measurement point coordination system and method for civil aircraft testing that is more intuitive, easier to operate, and effectively improves the convenience and accuracy of flight test modification design, thereby effectively improving the design efficiency of civil aircraft.

[0008] To achieve the above objectives, the present invention provides a measurement point coordination system and method for civil aircraft testing as follows: In a first aspect, embodiments of the present invention propose a test point coordination system for civil aircraft testing, characterized in that the system comprises: A mapping relationship storage module is used to store first mapping relationship data, wherein the first mapping relationship data consists of the mapping relationship between the name of each civil aircraft part and the position of the civil aircraft part in the civil aircraft model; The measurement point response module is used to respond to measurement point selection information and obtain a measurement point parameter information document based on the measurement point selection information. The measurement point parameter information document includes data information of the measurement points corresponding to each civil aircraft part to be measured. The data information of the measurement points to be measured includes data information that can reflect the position of the corresponding civil aircraft part. The measurement point response module is also used to generate a first model based on the measurement point parameter information document and the first mapping relationship data. The first model includes models selected from the civil aircraft models that match the civil aircraft parts to be measured. The test modification model library module is used to store alternative test modification models; A loading instruction response module is used to respond to a model loading instruction and generate a second model, the second model including the model formed after loading the corresponding test modification model onto the part of the civil aircraft to be tested; The data interaction module is connected to the measurement point response module and the loading instruction response module. The data interaction module is used to receive instruction information obtained from different devices and to transmit and display measurement point data information between different devices. The instruction information includes measurement point selection information and model loading instructions. The data information includes a civil aircraft model, a first model, and a second model.

[0009] The aforementioned test point coordination system applied to civil aircraft testing, wherein the test point response module includes: The measurement point information aggregation module is used to generate the measurement point parameter information document based on several preset format civil aircraft flight test parameter tables in the measurement point selection information. Each civil aircraft flight test parameter table includes data information of the corresponding civil aircraft part to be tested, and the data information of each civil aircraft part to be tested includes data information that can reflect the position of the corresponding civil aircraft part. The structure tree generation module is used to process the data information in the measurement point parameter information document based on a preset hierarchical division standard to generate test flight measurement point structure tree data. The data interaction module can transmit the test point structure tree data based on instructions.

[0010] The aforementioned test point coordination system for civil aircraft testing further includes: The allocation instruction response module is connected to the data interaction module. The allocation instruction response module is used to respond to allocation instructions, divide the test tasks recorded in the test point parameter information document based on the test point structure tree data, and push each divided test task to the corresponding test task docking device through the data interaction module. The test point filtering module is located in the corresponding test task docking device. The test point filtering module is used to filter the test points in the first model that are not related to the received test task based on the received test task, so as to generate a third model. When the loading instruction response module responds to the model loading instruction, it loads the test modification model onto the third model to generate the second model.

[0011] In the aforementioned test point coordination system applied to civil aircraft testing, when new test point selection information is received, the test point response module iterates the original test point selection information based on the new test point selection information, and the system restarts based on the new test point selection information.

[0012] Secondly, embodiments of the present invention also provide a measurement point coordination method applied to civil aircraft testing, the method comprising: Store first mapping relationship data, wherein the first mapping relationship data consists of the mapping relationship between the name of each civil aircraft part and the position of the civil aircraft part in the civil aircraft model; The system responds to measurement point selection information and obtains a measurement point parameter information document based on the measurement point selection information. The measurement point parameter information document includes data information of the measurement points corresponding to each civil aircraft part to be measured. The data information of the measurement points to be measured includes data information that can reflect the position of the corresponding civil aircraft part. The measurement point response module is also used to generate a first model based on the measurement point parameter information document and the first mapping relationship data. The first model includes models selected from the civil aircraft models that match the civil aircraft parts to be measured. In response to the model loading command, a second model is generated, which includes the model formed after loading the corresponding test modification model onto the part of the civil aircraft to be tested; During the operation of the method, a data interaction module is used to receive instruction information from different devices and to transmit and display measurement point data information between different devices. The instruction information includes measurement point selection information and model loading instructions, and the data information includes a civil aircraft model, a first model, and a second model.

[0013] The aforementioned measurement point coordination method applied to civil aircraft testing, wherein the step of responding to measurement point selection information and obtaining a measurement point parameter information document based on the measurement point selection information specifically includes: This is used to generate the test point parameter information document based on several preset format civil aircraft test flight parameter tables in the test point selection information. Each civil aircraft test flight parameter table includes data information of the corresponding civil aircraft part to be tested, and the data information of each civil aircraft part to be tested includes data information that can reflect the position of the corresponding civil aircraft part.

[0014] The aforementioned measurement point coordination method applied to civil aircraft testing further includes: The data information in the measurement point parameter information document is processed based on a preset hierarchical division standard to generate test flight measurement point structure tree data; The test flight measurement point structure tree data is transmitted based on the instructions.

[0015] The aforementioned measurement point coordination method applied to civil aircraft testing further includes: In response to the allocation command, based on the test point structure tree data, the test tasks recorded in the test point parameter information document are divided, and each divided test task is pushed to the corresponding test task docking device through the data interaction module. Based on the received test task, the test points in the first model that are unrelated to the received test task are filtered out to generate a third model; In response to the model loading instruction, the test modified model is loaded onto the third model to generate the second model.

[0016] In the aforementioned test point coordination method applied to civil aircraft testing, when new test point selection information is received, the test point response module iterates the original test point selection information based on the new test point selection information and re-runs the method based on the new test point selection information.

[0017] Thirdly, embodiments of the present invention also provide a computer-readable storage medium, wherein a computer program is stored on the computer-readable storage medium, and when the computer program is executed by a processor, it implements the steps of the method described in the second aspect above.

[0018] The beneficial effects of the measurement point coordination system and method of the present invention applied to civil aircraft testing are as follows: This invention establishes a mapping relationship between the names of various civil aircraft parts and their positions in the civil aircraft model, and sets up a test modification model library module that includes alternative test modification models. This allows the system to generate a corresponding model matching the civil aircraft part to be tested after the user inputs the test point selection information. Furthermore, it can generate a model after loading the corresponding test modification model onto the civil aircraft part to be tested according to the model loading instruction. This enables the system to transmit data in the model format on different devices, allowing different departments to obtain more intuitive information data through the received model data.

[0019] In some embodiments, test flight test point structure tree data can also be generated based on parameter information documents, so that different test point tasks can be assigned through the test flight test point structure tree data when performing task allocation. This allows departments performing different test tasks to only acquire model data corresponding to the assigned test task during the test modification model loading design process, reducing unnecessary data interference.

[0020] The measurement point collaboration system and method of this invention, applied to civil aircraft testing, facilitates the allocation of measurement points by the civil aircraft design department during flight test modification design. The flight test modification department can load the test modification model based on the acquired model of the civil aircraft part to be tested, and the generated second model is fed back to the civil aircraft design department for review. The civil aircraft design department can determine whether the test modification model meets the requirements through the measurement point model image. The flight test engineering department can also allocate tasks based on the flight test measurement point structure tree data, making the allocation operation more convenient. The measurement point collaboration system and method of this invention effectively improves intuitiveness and ease of operation, is suitable for cross-departmental collaborative work, ensures the convenience and accuracy of flight test modification design, and effectively improves the efficiency of civil aircraft design.

[0025] To make the technical means, inventive features, objectives, and effects of the invention readily understandable, the invention is further illustrated below with reference to specific figures. However, the invention is not limited to the embodiments described below.

[0026] It should be noted that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are only used to complement the content disclosed in the specification for those skilled in the art to understand and read, and are not intended to limit the conditions under which the present invention can be implemented. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and objectives that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0027] It should be noted that in this article, relational terms such as “first” and “second” are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0028] To better adapt to the characteristics of multi-departmental collaboration, mutual cooperation, and iterative processes required in flight test modification design, this invention presents a measurement point collaboration system and method for civil aircraft testing. This system enhances the intuitiveness of determining measurement point locations and test modification locations, effectively improving design efficiency. The following detailed description of the measurement point collaboration system and method for civil aircraft testing, using specific embodiments, further illustrates this invention: First embodiment: This embodiment provides a test point coordination system for civil aircraft testing, including: A mapping relationship storage module is used to store first mapping relationship data, wherein the first mapping relationship data consists of the mapping relationship between the name of each civil aircraft part and the position of the civil aircraft part in the civil aircraft model; The measurement point response module is used to respond to measurement point selection information and obtain a measurement point parameter information document based on the selection information. The measurement point parameter information document includes data information of the measurement points corresponding to each civil aircraft part to be measured. The data information of the measurement points includes data information reflecting the location of the corresponding civil aircraft part (such as the name of the corresponding civil aircraft part and its coordinate position). The measurement point response module is also used to generate a first model based on the measurement point parameter information document and the first mapping relationship data. The first model includes models selected from the civil aircraft models that match the civil aircraft part to be measured. For example, in implementation, the name and coordinate position of the civil aircraft part in the data information of the measurement points can be used to match a model that matches the civil aircraft part to be measured. In addition to data information reflecting the location of the corresponding civil aircraft part, the measurement point parameter information document may also include other data information set by the civil aircraft design department, such as the detection requirements for the corresponding measured location. In specific implementation, the measuring point response module includes: The measurement point information aggregation module is used to generate the measurement point parameter information document based on several preset format civil aircraft flight test parameter tables in the measurement point selection information. Each civil aircraft flight test parameter table includes data information of the corresponding civil aircraft part to be tested, and the data information of each civil aircraft part to be tested includes data information that can reflect the position of the corresponding civil aircraft part. The structure tree generation module is used to process the data information in the measurement point parameter information document based on a preset hierarchical division standard to generate test flight measurement point structure tree data, wherein the test flight measurement point structure tree data can be associated with the organizational hierarchy and test items of civil aircraft; The data interaction module can transmit the test test point structure tree data based on instructions; The allocation instruction response module is connected to the data interaction module. The allocation instruction response module is used to respond to allocation instructions, divide the test tasks recorded in the test point parameter information document based on the test point structure tree data, and push each divided test task to the corresponding test task docking device through the data interaction module. The test point filtering module is located in the corresponding test task docking device. The test point filtering module is used to filter the test points in the first model that are not related to the received test task based on the received test task, so as to generate a third model. When the loading instruction response module responds to the model loading instruction, it loads the test modification model onto the third model to generate the second model; The test modification model library module is used to store alternative test modification models; A loading instruction response module is used to respond to a model loading instruction and generate a second model, the second model including the model formed after loading the corresponding test modification model onto the part of the civil aircraft to be tested; The data interaction module is connected to the measurement point response module and the loading instruction response module. The data interaction module is used to receive instruction information obtained from different devices and to transmit and display measurement point data information between different devices. The instruction information includes measurement point selection information and model loading instructions. The data information includes a civil aircraft model, a first model, and a second model.

[0029] When new measurement point selection information is received, the measurement point response module iterates the original measurement point selection information based on the new information, and the system restarts based on the new information.

[0030] To more intuitively illustrate the operational logic of the measurement point coordination system applied to civil aircraft testing in the above embodiments, the following will combine... Figure 1 The following examples will be used to illustrate this point. Figure 1 This is a flowchart of a flight test modification design for a measurement point coordination system applied to civil aircraft testing, based on an embodiment of the present invention: The measurement point collaboration system applied to civil aircraft testing is implemented using CATIA 3DE. When this measurement point collaboration system for civil aircraft testing is running, a detailed design model of the entire civil aircraft (i.e., the civil aircraft model) can be established first, and a flight test modification model library (i.e., the test modification model library module) can be established.

[0031] like Figure 1 As shown, when using this system for flight test modification design, the relevant professional departments provide the corresponding chapter of the "Civil Aircraft Flight Test Parameter Table". The "Civil Aircraft Flight Test Parameter Table" is a table with a predetermined format. The measurement point information aggregation module can integrate multiple received "Civil Aircraft Flight Test Parameter Tables" to generate a measurement point parameter information document. In this embodiment, the measurement point parameter information document can be in the form of an Excel spreadsheet, that is, the measurement point parameter information document is a flight test measurement point collaborative scenario table that gathers all the information from the "Civil Aircraft Flight Test Parameter Tables".

[0032] In practice, the "Flight Test Point Collaborative Scenario Table" includes: corresponding sheets set according to different flight test parameter types. Each sheet contains corresponding serial numbers (i.e., row and column numbers in the table), parameter names, software identifiers (unique), test point related attributes, three-dimensional position coordinates, sortie information, subject information, equipment model, equipment number, three-dimensional entity shape and other characteristic attributes. It also has exclusive attributes corresponding to each type of test modification. The relevant information belongs to the data information of the test points corresponding to each civil aircraft part to be tested, and the name of the civil aircraft part can be reflected through the relevant information. For example, the civil aircraft part can be identified through the software identifier. A unique "flight test point structure tree" can be created and maintained through the structure tree generation module; Once the test point selection information is updated, the "Test Flight Test Point Structure Tree" can read the input "Test Flight Test Point Collaborative Scenario Table", analyze the table, and add, delete, modify, and query the existing test flight test points in the "Test Flight Test Point Structure Tree" to achieve iterative updates.

[0033] It should be noted that the system maintains only one measurement point structure tree for each round of flight test modification design. For example, the structure of this measurement point structure tree could be as follows: First layer: Root, equipment body, named "Test Flight Measurement Point Structure Tree". This layer only contains sub-structure tree assemblies. Second layer: Assemblies, named according to the name of each sheet page. Third layer: Parts, generating one measurement point from each piece of information on the current sheet page. Measurement point name: Parameter name; Unique measurement point part number: Software identifier (unique); Remaining column information for measurement points: Automatically created by the platform.

[0034] The tree structure will be updated synchronously during subsequent iterations.

[0035] After the "Flight Test Measurement Point Structure Tree" for each specialty is configured, the Flight Test Engineering Department uses the online attribute filtering function to filter measurement points and assigns online validity to the measurement points on the "Flight Test Measurement Point Structure Tree". Each specialty can view the data in real time and modify the measurement point positions and models. The flight test and modification specialists use this system to combine the full aircraft model with the measurement points and their effectiveness, and perform online interference filtering to identify the aircraft parts corresponding to each measurement point.

[0036] Based on the test and modification equipment attributes contained in the test point attribute column, the flight test and modification professionals select equipment from the flight test and modification model library online and insert it into the full aircraft model for online design of flight test and modification.

[0037] Since all the above steps are carried out on the collaborative platform of this system, the design and flight test engineering professionals can conduct real-time monitoring and optimization of the equipment installation results during the design and installation of the flight test modification equipment.

[0038] Right now Figure 1 The portion of the online collaborative platform highlighted refers to the work performed by this system. Specifically, the professional processes involved are those executed by the design department using this system, the flight test engineering patent process is those executed by the flight test engineering department using this system, and the flight test and modification professional process is those executed by the flight test and modification department using this system. This system can also transmit instruction information to the three departments; for example, the design department can transmit measurement point adjustment instructions to the flight test and manufacturing departments through the system. This can be achieved through the instruction allocation and response module of this application. Figure 1 The system includes operations for filtering measurement point attributes, adding validity to measurement points, and filtering measurement point attributes and validity. Specifically, when the measurement point parameter information document includes information about the items to be tested at the measurement points, the flight test can comprehensively consider information such as the item type and measurement point location, and then assign different tasks to different test and modification departments through an operation structure tree.

[0039] The measurement point filtering module can combine the assigned tasks to display different measurement point models to different testing and modification departments. This allows the testing and modification departments to select the corresponding testing and modification model (which can be a sensor or other component used to implement the detection function) and load it onto the corresponding measurement point to form a second model for the design department to view.

[0040] Because this system can aggregate measurement point information, different design departments can input different civil aircraft flight test parameter tables into the system, which will then aggregate them into a flight test measurement point collaborative scenario table. This table, combined with preset hierarchical configuration rules, will generate a flight test measurement point structure tree. Figure 2 This is a schematic diagram of a structure tree. The system can generate test flight collaborative measurement points on the "Test Flight Measurement Point Structure Tree". Based on the input table requirements, it automatically fills in the information in the collaborative measurement point attribute column, generates the corresponding measurement point shape at the determined three-dimensional spatial location as required, and defines the installation range. When determining the validity of test points in the flight test engineering phase, target test points can be filtered online and validity assigned based on the attributes included in the test points. Design and flight test modification professionals can observe the allocation results in real time on the platform and provide modification suggestions. When the flight test and modification specialist pulls the flight test and modification model library online to install the test and modification equipment, the design specialist and the flight test engineering specialist can observe the equipment selection and installation status online in real time and make modification suggestions. All processes are conducted online, enabling real-time collaboration among the three related disciplines.

[0041] Second embodiment: This embodiment provides a measurement point coordination method for civil aircraft testing, the method comprising: Store first mapping relationship data, wherein the first mapping relationship data consists of the mapping relationship between the name of each civil aircraft part and the position of the civil aircraft part in the civil aircraft model; In response to the measurement point selection information, a measurement point parameter information document is obtained based on the measurement point selection information. The measurement point parameter information document includes data information of the measurement points corresponding to each part of the civil aircraft to be measured, specifically including: The test point response module is used to generate a test point parameter information document based on several preset format civil aircraft flight test parameter tables in the test point selection information. Each civil aircraft flight test parameter table includes data information of the corresponding civil aircraft part to be tested, and the data information of each civil aircraft part to be tested includes data information that can reflect the position of the corresponding civil aircraft part. The test point data information includes data information that can reflect the position of the corresponding civil aircraft part. The test point response module is also used to generate a first model based on the test point parameter information document and the first mapping relationship data. The first model includes models selected from the civil aircraft models that match the civil aircraft part to be tested. The data information in the measurement point parameter information document is processed based on a preset hierarchical division standard to generate test flight measurement point structure tree data; The data of the flight test measurement point structure tree is transmitted based on the instructions; In response to the allocation command, based on the test point structure tree data, the test tasks recorded in the test point parameter information document are divided, and each divided test task is pushed to the corresponding test task docking device through the data interaction module. In response to the model loading command, a second model is generated, which includes the model formed after loading the corresponding test modification model onto the part of the civil aircraft to be tested; In practice, based on the received test task, test points in the first model that are unrelated to the received test task are filtered out to generate a third model; When responding to the model loading command, the test modification model is loaded onto the third model to generate the second model. (For example, during the operation, the test flight can filter the test points assigned to the first test flight aircraft by selecting test flight flights as the filter condition based on the test flight test point structure tree data displayed in the interface. The instantiated test points after the flight flight selection can be used as the spatial condition for filtering the prototype environmental model. Then, the environmental model around the test points of the first test flight aircraft that need to install sensors is obtained after the prototype is filtered.) During the operation of the method, a data interaction module is used to receive instruction information from different devices and to transmit and display measurement point data information between different devices. The instruction information includes measurement point selection information and model loading instructions, and the data information includes a civil aircraft model, a first model, and a second model.

[0042] When new measurement point selection information is received, the measurement point response module iterates the original measurement point selection information based on the new information and re-runs the method based on the new information.

[0043] Figure 3 This is a view showing the interface of the measurement point coordination system of the present invention applied to civil aircraft testing, in one embodiment. Figure 3 The system provides two interfaces for users to refer to simultaneously. The sphere on the left interface represents the selected measurement point location, while the image on the right interface is a model of the corresponding mechanism location generated based on the selected measurement point location (a test modification model can be loaded at the corresponding location). In practical implementation, the various components in the civil aircraft can be associated according to instructions, so that when displaying the measurement point location, the mechanism to which the measurement point component belongs can be displayed synchronously, allowing the specific location of the relevant component to be determined through the mechanism. Figure 3 The arrows in the diagram are used to indicate the relationship between components in two interfaces. The left side of each interface is the structure tree.

[0044] This system enables seamless online collaboration from the initial request to the fulfillment of requirements in flight test and modification operations. When the design team uploads the "Flight Test Point Collaboration Scenario Table," the corresponding flight test point structure tree can be automatically and quickly generated. When the flight test engineering team assigns validity to the test points in the structure tree, the data can be synchronized in real time to the design and testing / modification teams, allowing each team to filter target test points based on attribute information.

[0045] An online test and modification structure library has been established. The test and modification professionals can pull the corresponding equipment from the online model library in real time and install it into the digital prototype of the civil aircraft. It can also be synchronized to the design and test engineering professionals in real time.

[0046] All three disciplines can annotate and modify the digital model. When modifications are made, the prompt information will be synchronized to other disciplines, which is conducive to the rapid, efficient and accurate conduct of flight test, modification and design work.

[0052] The beneficial effects of the measurement point coordination system and method of the present invention applied to civil aircraft testing are as follows: This invention establishes a mapping relationship between the names of various civil aircraft parts and their positions in the civil aircraft model, and sets up a test modification model library module that includes alternative test modification models. This allows the system to generate a corresponding model matching the civil aircraft part to be tested after the user inputs the test point selection information. Furthermore, it can generate a model after loading the corresponding test modification model onto the civil aircraft part to be tested according to the model loading instruction. This enables the system to transmit data in the model format on different devices, allowing different departments to obtain more intuitive information data through the received model data.

[0053] In some embodiments, test flight test point structure tree data can also be generated based on parameter information documents, so that different test point tasks can be assigned through the test flight test point structure tree data when performing task allocation. This allows departments performing different test tasks to only acquire model data corresponding to the assigned test task during the test modification model loading design process, reducing unnecessary data interference.

[0054] The measurement point collaboration system and method of this invention, applied to civil aircraft testing, facilitates the allocation of measurement points by the civil aircraft design department during flight test modification design. The flight test modification department can load the test modification model based on the acquired model of the civil aircraft part to be tested, and the generated second model is fed back to the civil aircraft design department for review. The civil aircraft design department can determine whether the test modification model meets the requirements through the measurement point model image. The flight test engineering department can also allocate tasks based on the flight test measurement point structure tree data, making the allocation operation more convenient. The measurement point collaboration system and method of this invention effectively improves intuitiveness and ease of operation, is suitable for cross-departmental collaborative work, ensures the convenience and accuracy of flight test modification design, and effectively improves the efficiency of civil aircraft design.
