Design And Implementation Of Application System Software Of UAV Ground Station Based On MBSE

At present,drones play an important role in various industries and technologies.UAV ground station is an important part of guaranteeing UAV remote control and telemetry communication.It is not only the core support for the operation of the UAV system,but also the central node for information fusion and command control of the entire large system.Due to the increasing diversification of user requirements and the increasing complexity of ground stations,traditional design methods have been difficult to meet the current and future UAV ground station application system design.In order to achieve system integration and configurability and meet different users Use needs,need to introduce new methods and means.This paper proposes to introduce Model Based on Systems Engineering(MBSE)into the design and development of UAV ground station application system.This article first analyzes the research status and development trends of UAV ground station systems,and proposes and analyzes the problems in the ground station application system.Then based on the MBSE method,the UAV ground station application system is divided from top to bottom,and the system requirements are analyzed.Based on the system requirements,iterative function analysis is performed,and finally the design and synthesis are completed to complete the system design of the ground station application system architecture.In addition,in view of the particularity of the source of the subject,the hardware platform equipment corresponding to the UAV ground station is described.In the entire system development process,Qt is used as the development environment,and the MVC mode is used to separate the business logic and data of the program for corresponding development,increasing development efficiency and reducing maintenance in the later period.In terms of designing system communication links,in order to meet the user's multiple choice requirements,it supports multiple connection methods;the flight monitoring module implements one-key control,mission control and flight monitoring functions for the UAV through the MAVLink protocol.Route planning implements the functions of editing waypoints on the map,generating waypoint data,uploading route tasks and downloading route tasks.The ground station application system can control the drone to calibrate the level and the magnetic compass,feed back the calibration results with an intuitive graphical interface,reduce the user's difficulty of operation,and facilitate the user's use.Finally,the ground station application system was tested in terms of function and performance through actual UAV outdoor flight experiments to verify the feasibility and stability of the functions of each subsystem,meet the functional requirements,and be able to operate stably and reliably to achieve the expected results.
