Research And Implementation Of The Key Technology Of The Civil Airborne Software Integrated Development Platform

The successful operation of C919 aircraft breaks the situation that our civil aviation market has been occupied by European and American enterprises for a long time,so that more domestic software enterprises have the opportunity to participate in the development of civil airborne software research tasks.At present,there is still no a perfect integrated development platform for civil airborne software.This paper originates from the cooperative research project of China Aeronautical Radio Electronic Research Institute and Nanjing Xin Co.,Ltd.,which focuses on the realization of the civil airborne software integrated development platform.Firstly,the technical architecture of the platform is improved,then the key technologies are studied in depth,finally these technologies are applied to the platform.The main work and innovation of this paper are as follows:1)The civil airborne software integrated platform is improved.The overall architecture of the platform is optimized,and the core function of the platform is realized with workflow management system.The cost of system maintenance is reduced by controlling multiuser access through permissions.2)The civil airborne software airworthiness certification standard and the enterprise existing development standard comprehensive application plan is proposed,which improves the practicality of the existing research results,and instructs the enterprise to establish the civil airborne software development system quickly.3)The task assignment algorithm of workflow management system is improved.The multiple influencing factors are considered in the algorithm,and the concept of knowledge skill set is introduced to realize the two-way selection between users and tasks.Experimental results prove the optimization effect of the algorithm.4)A modified dynamic dendritic cell algorithm based on information entropy is proposed.By establishing the information entropy model of antigen data,the average difference between the detected antigen and the current antigen is quantified,which guarantees the safety and integrality of the airworthiness certification data.Experiments show that the algorithm has better detection effect.
