| With the development of information technology,the UAV in the geographical environment monitoring,disaster inspections,law enforcement,communications relay,military and other applications in all aspects of society,national defense,industry will show a strong advantage.In the current world,UAV is more and more important strategic position,all countries have invested heavily in research of UAV.The flight control system as the core component of the ground control station,it directly affects the flight safety of UAV and task execution.This thesis mainly studies the design and Realization of the flight control system of UAV Ground Station,and completed the system software programming and implementation.Application of the subject of this thesis mainly includes the multi thread programming,Qt’s signals and slots mechanism and reflection mechanism,network communication technology and XML access technology.This thesis firstly introduces the research status of UAV and UAV Ground Station,summed up the characteristics of the UAV flight control software,the functions of flight control software.And then elaborates several application technology involved in the process of developing,which lays the theoretical foundation for the realization of the software design.Then the thesis puts forward the technical architecture of the system,mainly describes the work mode switch function design content and communication rules etc.In the fourth chapter,starting from the specific implementation details,the system first,to achieve the communication layer,is proposed for data frame format and transmission of different scenarios of the uplink and downlink data reception and processing.Then the downlink data,control commands and user interface can be configured to three aspects of implementation are described.In the fifth chapter,the properties of various sectors,on the design and implementation of route planning function to give an overall description.At the end of the thesis,the system carried out several simulation tests,results show that the UAV flight control software with high reliability,real-time communication.It is proved that the system can meet the design requirements. |
