基于IMA的大型客机CNS系统集成试验和验证

基于综合模块化航空电子系统(IMA)的通信导航监视(CNS)系统与传统CNS的系统架构、信息 传输方式等都有很大的不同，所以需要研 究以IMA为信息处理核心、AFDX加RDIU为信息传输网络的航电系统架构中CNS 系统的集成实 验的技术途径和验证方法。提出了一种按照不同研制阶段将系统集成试验分为全模拟仿真 系统、半实物仿真系统、全实物仿真系统三阶段集成的技术途径和系统验证方法。该技术途 径和方法充分考虑不同阶段系统对集成试验和验证的需求，对CNS集成试验和验证设计具有 一定的借鉴意义。

Integrated test and validation for IMA-based large civil aircraft CNS

The system architecture and information transmission of Integrated Modular Avion ics(IMA) based Communication, Navigation and Surveillance(CNS) system is differe nt from that of traditional CNS. It is necessary to research methods for IMA- b ased and AFDX+RDIU as networks CNS integrated validation. According to developme nt stage requirements,three stages(full simulation system, half real equipment s ystem, full real equipment)integrated validation methods are proposed,whic h can meet the requirements of development stage and be useful to the CNS integ ration for reference.
