Research And Implementation Of UAV Control Station System Architecture Based On Model

As the application of UAV becomes more and more extensive,its functions are constantly expanded,and the application scenarios become more and more abundant,so the UAV control station system becomes more and more complex and changeable.In the case of model development and function upgrading,traditional document-based system engineering method has high redundancy,low document maintenance,low development cost control and serious repetitive design,which makes it difficult to meet the increasingly complex development needs.With the emergence of Model Based Systems Engineering(MBSE)method,the traceability of requirements,consistency of design and correctness of logic are well solved in theory,and a series of problems in the development of complex Systems are effectively avoided.In China,although MBSE method has been relatively popular in theory and is widely regarded as the future development trend in the industry,it is still in a state of stagnation in the application of MBSE method.In the process of promotion and practice in China,the MBSE method cannot be effectively combined with the local actual situation.This article in view of the traditional system engineering method based on the document in the UAV control station system development appeared in the problem,put forward in a large UAV control station system verification introducing MBSE methodologies in the development process of the project,as the research object,based on a set of MBSE localization method of UAV control station system development and design process,finishing from requirements analysis to the deliverable design practice in whole life cycle.This paper studies the system engineering methodology,understands the essence of the system engineering methodology,and deeply explores the basic principles and three pillars of system engineering based on the model.Through the systematic study of the existing and mature modeling language,modeling methods and modeling tools,the localization development method of developing the system architecture of UAV control station is determined.In order to solve the problem that large multi-function UAV control station system is prone to repeat design in the case of changing application scene and development of multi-function UAV.The requirement tracking matrix corresponding to the system module is completed by establishing the requirement model with MBSE.Aiming at the problems of system architecture upgrading and repeated design of series model aircraft in UAV control station.This paper puts forward an innovative open,extensible,general UAV control station system architecture,according to the basic characteristics and application of UAV control station system scenarios,by setting the basic module subsystem,subsystem and the reserved task module design of the UAV control station system open general architecture and system interface.At the same time,by establishing different design models at each stage of the design and using the method of model-driven development,the whole process modeling of UAV control station system based on MBSE method was completed.Finally,in determining the UAV control station,after the main content of system verification in the Rhapsody environment has set up a platform system architecture based on state diagram validation,the logic simulation,and generate a system architecture based on c + + language code,and completed the task table interface design,structure model of the package and the code requirements,completed the task analysis and tracking analysis,functional design,architecture,weigh the validation logic to the system integration,design project delivery system design of the whole life cycle of practice.
