Description

Technical Field

[0001] The present invention relates to the technical field of flight control systems, and in particular to a B / S-based fly-by-wire flight control system engineering development and management platform. Background Art

[0002] The flight control system is the most critical system for safe flight and mission execution of aircraft, especially for modern advanced aircraft since the advent of fly-by-wire flight control systems. Compared with other airborne systems, the flight control system has a distinct characteristic from the perspective of development management, which is "getting up early and arriving late". Due to the characteristics of the flight control system development that starts early, lasts for a long time, and has a complex development and verification relationship, in order to ensure the development progress of the flight control system, the engineering development management of the flight control system must be started based on the system engineering method at the beginning of the project demonstration to ensure the orderly progress of the development process and thus ensure the completion of the task according to the node. The current engineering development management of the flight control system has the following difficulties: Flight control systems are developed using systems engineering principles. This involves multiple workflows, parallel processes, integrated multi-process integration, and recursive iteration of local processes, further increasing the complexity of the development process. Currently, flight control system development has yet to achieve refined, digital, and integrated management across the entire process. This lack of guidance and constraints hinders comprehensive monitoring and collaboration mechanisms.

[0003] Flight control system development utilizes a top-down decomposition process, moving from the aircraft level to the system level, to the subsystem level, to the equipment level, and even to the component level. Each step requires a large amount of input and output information. Flight control system engineering development management relies on this information for scientific and rigorous evaluation and decision-making. Currently, this information is primarily static reports, relying primarily on manual statistics and tracking. This lack of unified data management and comprehensive utilization hinders the management and monitoring of development processes and key elements.

[0004] Flight control system development involves multiple disciplines, including system architecture, electromechanical systems, electronics, software, control laws, simulation, and testing, encompassing a wide range of expertise. However, the knowledge, tools, and product assurance requirements associated with flight control system development are not fully integrated into the development process, relying instead on individual experience and expert review at key milestones. This provides insufficient support for development and presents quality risks. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides a B / S-based fly-by-wire flight control system engineering development management platform, which has the advantages of integrating development processes, knowledge, and development information, realizing the integration and lean collaboration of complex processes, multiple personnel, and multi-disciplinary knowledge elements, as well as the management and monitoring of design, testing, production, and manufacturing development processes and elements, thereby solving the problems of the above-mentioned technologies.

[0011] Preferably, the task management unit includes task node setting and task feedback; The task node setting is used by managers to set nodes for specific work tasks; the task feedback is used by designers to provide feedback on tasks to promote communication and collaboration.

[0012] Preferably, the knowledge base module includes vertical organization and horizontal organization; The vertical organization is expressed as follows: the knowledge base content is arranged in the order of the six stages of flight control system development, with the output of the previous stage serving as the input of the next stage, forming a closed-loop development process; The horizontal organization is manifested in the following ways: through work decomposition units and work description units, the relationship between the various disciplines within the flight control system is described, the coordination relationship between the flight control system and the aircraft overall, structure, avionics and electromechanical disciplines is clarified, and the implementation of specific work is guided.

[0013] Preferably, the project creation module is also used for project creation, knowledge base content replication, project customization, version management, and project tracking and management; The project creation is used for users to quickly create new projects according to their needs, allowing users to extract and copy relevant information from the platform's knowledge base to better meet the needs of new projects; The knowledge base content copy function is used by the user to select relevant knowledge base entries, including work breakdown and work description content within a certain development phase unit, and quickly copy them to a new project to save time and improve project start-up efficiency; The project customization is used to create new engineering projects.

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 making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 4 As shown, a B / S-based fly-by-wire flight control system engineering development management platform is composed of a human-computer interaction interface, a knowledge base module, an engineering creation module, and a model experience module; The knowledge base module is only for the full use of platform R&D personnel. Platform users can only view it and have no right to modify it. Platform users can create an engineering module, copy the knowledge base module as a whole, and modify and improve it according to the needs of the model. After logging into the platform main window, the knowledge base interface will be opened in the main window; The project creation module is used to authorize platform users to create new projects, make adaptive changes in new projects, import new projects, export project files, and implement printing functions within the interface; The human-computer interaction interface is used to connect users. After logging into the platform through the human-computer interaction interface, users can view the knowledge base content, create a new project, and copy the knowledge base content to the new project, or import external files into the new project to improve the project content. At the same time, the new project supports adding or deleting, and the project content can be exported and printed after being saved; The model experience module is used to record and summarize the development experience of different models of flight control systems, including success cases, failure lessons and design optimization, for reference in subsequent projects.

[0019] Specifically, the knowledge base module includes a development stage unit, a work breakdown unit, a work description unit and a task management unit.

[0020] The development stage unit is a first-level unit of the knowledge base module interface. Its contents include the main work package contents and descriptions of the six stages of flight control system development from feasibility study to design finalization (feasibility study, scheme demonstration, preliminary design, detailed preliminary design, detailed design, and design finalization), as well as the relationship between the flight control system and other aircraft disciplines (systems). It clearly expresses the design input and output of the flight control system, and can guide the aircraft development management department to formulate a zero-level network diagram and guide the flight control system design discipline to formulate a first-level network diagram and annual and quarterly plans.

[0021] Network diagram guidance can provide zero-level network diagrams and task management, which helps to plan a reasonable project schedule at the beginning of the project, ensure the orderly progress of work in each stage, reduce blindness between stages, and improve the transparency of the entire process.

[0022] The work decomposition unit is a secondary unit of the knowledge base module interface. Its content includes the work of the flight control system at each development stage, broken down into each minimum work unit (such as reports, technical sheets, drawings, coordination sheets, etc.), and can guide the formulation of monthly or even weekly work plans for the development of the flight control system.

[0023] The work description unit is a third-level unit of the knowledge base module interface. Its content is a work description compiled based on the smallest work unit in the "Flight Control System Development Work Decomposition", which clarifies the purpose, content, requirements and results of each work content, and can guide engineers to complete the development work with high quality.

[0024] The task management includes task node setting and task feedback; the task node setting is used by managers to set nodes for specific work tasks; the task feedback is used by designers to provide feedback on tasks to promote communication and collaboration; corresponding to specific work tasks, managers can set task nodes and designers can provide task feedback.

[0025] From a vertical perspective, the contents of the knowledge base module are arranged in the order of the six stages of aircraft development. The content of the previous stage serves as the input of the next stage, and the content of the next stage serves as the development of the previous stage.

[0026] From a horizontal perspective, the content of the knowledge base module describes the relationship between various disciplines within the flight control system through work decomposition and work instructions, provides the coordination relationship between the flight control system and the aircraft overall, structure, avionics, electromechanical and other disciplines, and guides the implementation of specific work.

[0027] Specifically, the project creation module consists of project creation, knowledge base content replication, project customization, version management, and project tracking and management.

[0028] Project creation: Users can quickly create new projects based on their needs, allowing users to extract and copy relevant information from the platform's knowledge base to better meet the needs of new projects; The knowledge base content is copied; the user selects relevant knowledge base entries, including work breakdown and work description content within a certain development phase unit, and quickly copies them to the new project to save time and improve project start-up efficiency; Project customization: After creating a new engineering project, the user can modify and improve the copied knowledge base content according to the characteristics and requirements of the specific model to ensure that all documents and plans can specifically reflect the needs of the new project; Version management: Supports version control to ensure knowledge inheritance and updates between different projects, so that when new projects refer to the experience of old projects, they can clearly understand the modification history; Project tracking and management supports tracking and management of created projects, including project progress, task allocation, and resource management functions to ensure that projects proceed as planned.

[0029] Phase Division and Work Decomposition: The platform divides the development process into six distinct phases: feasibility study, solution verification, preliminary design, detailed design, and design finalization. Each phase has specific work packages and output requirements, forming a linear and clear process. Furthermore, breaking down work into the smallest units further refines the process, ensuring effective oversight and management of every link.

[0030] In the knowledge base, information is organized by development stage, forming a closed-loop process. The output of each stage becomes the input of the next stage. This approach not only helps integrate knowledge, but also promotes the effective flow of information within the team, ensuring that every member can access the most relevant knowledge resources.

[0031] The model experience module specifically records the development experience of different models, including successful cases and failure lessons, providing valuable reference for new projects. This experience sharing mechanism can help the team quickly find solutions and reduce repeated errors, thereby achieving effective knowledge inheritance.

[0032] Through the task management function, managers can set specific task nodes and promote communication and collaboration among responsible persons through feedback mechanisms. This flexible task management method ensures that different professionals can participate in projects together, exchange different views, and thus promote interdisciplinary collaboration.

[0033] In the knowledge base module, the horizontally organized knowledge framework clarifies the coordination information between the flight control system and other aircraft disciplines. This horizontal knowledge description enables various disciplinary teams to understand each other's needs and progress, and promotes efficient collaboration among multiple disciplines.

[0034] Specifically, the project creation module provides users with fast and flexible project creation functions, allowing teams to make rapid adjustments based on project requirements and reduce unnecessary waste of resources. This lean concept runs through the entire project life cycle.

[0035] Furthermore, through task feedback and quality guidance, the platform can monitor project progress in real time and provide quality standards and improvement suggestions. This real-time feedback mechanism enables the team to adjust strategies in a timely manner during implementation and improve the adaptability and efficiency of the project.

[0036] Furthermore, the management platform of this application clearly divides the design process into several stages, each of which has specific work packages and output requirements. This stage-by-stage management ensures that every link in the design process is monitored to avoid missing key work.

[0037] Furthermore, this application supervises the work progress and quality of the design team through task allocation and management. The task setting with clear responsibilities helps each designer to clarify his or her own duties, and provides real-time feedback on the completion status of the work to ensure that the design proceeds as planned.

[0038] Furthermore, the knowledge base module of this application integrates past test data, success and failure cases, and corresponding design optimization suggestions. The centralized storage of this information provides valuable reference for the trial phase of new projects, helping project teams reduce the risk of trial failure when setting up trial plans.

[0039] In addition, the knowledge base provides detailed work instructions and operating instructions, providing specific operating specifications for the production and manufacturing stages, ensuring that each link has clear execution standards, thereby reducing errors caused by improper operation.

[0040] Furthermore, during the trial phase of this application, the platform can monitor the progress and results of the trial through real-time data entry and analysis functions. Once an abnormal situation is discovered, the team can quickly take measures to adjust the trial plan to ensure the safety and effectiveness of the trial process.

[0041] Furthermore, the management platform of this application has resource management functions to ensure that resources can be efficiently allocated and used during the production and manufacturing process, which reduces resource waste and improves production efficiency.

[0042] In addition, the resource management function ensures that different versions of the project can be compared and traced, ensuring that the team can clearly understand the modification history of each version during the design, testing and production processes. This transparency improves the effectiveness of project management and ensures that all modifications and updates can be monitored and reviewed.

[0043] The management platform supports real-time tracking of the entire project, including progress, tasks, resources, and test results. This comprehensive monitoring mechanism enables management to obtain project status in a timely manner and make timely decisions.

[0044] The structural design of the management platform allows teams from different disciplines to share information and data, thereby improving the efficiency of interdisciplinary cooperation. This is particularly important for the development of complex flight control systems because it involves knowledge and technologies from multiple fields.

[0045] This application integrates information from each link of design, testing, production and manufacturing through the knowledge base module and model experience module, making the information flow unimpeded. This integration enables each department to maintain consistency in requirements, design modifications, and test results, thereby promoting collaborative work in each link.

[0046] See also Figure 1 As shown, this is the operation flow chart of the management and control platform of this application. After the user logs in to the platform through the human-computer interface, he can view the knowledge base content, create a new project, and copy the knowledge base content to the new project, or import external files into the new project to improve the project content. At the same time, the new project supports adding / deleting. After the project content is saved, the file can be output and printed.

[0047] See also Figure 2 As shown, this is a flowchart for importing a new project into the management and control platform of this application. When in use, the user clicks the "Development Information Edit" button, and the management platform will confirm whether the user has the authority to edit based on the user name. If the user does not have the authority, the interface will remind the user that he does not have the authority; if the user has the authority, the editing interface will be entered. After entering the editing interface, the user can create a new project or choose to modify an existing project. After creation, you can select the file to be imported under the current project and submit it. The platform parses the files submitted by the user and converts the file format (Word, Excel, Project), and finally displays the operation results (success, failure), and displays the parsed files on the interface, which may include the purpose, content, requirements and results of each work content.

[0048] See also Figure 3 As shown, when the flowchart of a new project is exported for the management and control platform of this application, the user selects the content to be exported in the current project operation interface and submits it. The management platform will confirm whether the user has the authority to export based on the user name. If the user does not have the authority, the interface will remind the user that the user does not have the authority; if the user has the authority, the file will be exported in the format required by the user (Word, Excel, Project) for the convenience of user review.

[0049] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
