The Design And Implementation Of Cockpit Display System Software Based On SCADE

The software design of traditional UAV cockpit display system is usually realized by manual code programming,which has long development cycle and high cost.With the rapid development of aerospace electronic system software,the requirement for the safety,reliability and development efficiency of unmanned aerial vehicle cockpit display system is becoming more and more stringent.In order to solve the shortcomings of traditional solutions,it is necessary to find a more effective way to design and implement the cockpit display system.This paper studies the design and implementation of the cockpit display system of UAV based on SCADE(Safety-Critical Application Development Environment)model.On the basis of discussing the technology of SCADE modeling for UAV cockpit display system,this paper introduces in detail the requirement analysis,overall design,detailed design and implementation of the software for UAV cockpit display system,as well as the final test and verification work.Firstly,this paper introduces the model-based development verification,compares the model-based software development with the traditional software development process,and determines the overall design scheme of the subject based on SCADE modeling combined with manual code.Secondly,the detailed design of each module of UAV cockpit display system is carried out,including the detailed design of display structure and the detailed design of system software flow.Thirdly,according to the design requirements of each functional module in the overall requirements of the UAV cockpit display system,the realization of the model building,the integration of the model automatic generation code,the data receiving module,the route displaying module,the fault information displaying module,the real-time height and position curve displaying module and the three-dimensional model displaying module of the UAV cockpit display system are completed.Then,the software of each module is integrated,the code is optimized,and the Open-loop test and verification of the UAV cockpit display system are carried out.Finally,the validity of the design is verified by the closed-loop verification of the system,and the feasibility of realizing the cockpit display system based on SCADE model in function and performance is proved.The software development of UAV cockpit display system based on SCADE meets the software development requirements of a certain type of UAV cockpit display system,which proves that the model-based technology and implementation scheme adopted in this paper are effective.This scheme has the advantages of strong generality and flexible software development.It has important application value in the development process of UAV cockpit display system software.
