摘    要:依照综合模块化航空电子系统(Integrated modular avionics ,IMA)平台的健壮性分区特点,IMA平台必须能够为驻留应用和驻留功能提供健壮分区隔离和其他保护能力,这些措施要允许多个驻留应用共享一个平台及平台上的资源,且自身的资源支持系统级分布功能在容错网络上运行。根据综合模块化航空电子系统开发指南与认证考虑RTCA DO-297标准中关于IMA平台健壮性分区、安全性以及认可证明数据的要求,本文对IMA平台分区分析展开研究,重点对IMA平台及其组件通用处理模块(General processing module, GPM)、航空数据网络ARINC664交换机和远程数据集中器(Remote data concentrator, RDC)进行分区分析方法的研究。给出每个组件的分区分析策略和目标,明确每个任务需要进行的活动,为IMA平台及其组件的健壮性分析、缓解潜在风险、安全性分析和认可提供充足的证据。

关 键 词:IMA  平台  分区分析  通用处理模块  ARINC664交换机  远程数据集中器

Abstract:According to the integrated modular avionics (IMA) platform characteristics of robust partitioning, the IMA platform should be capable of providing robust partitioning and other protection for hosted applications and hosted functions, which allows multiple hosted applications to share a platform and its resource and the resource can support systematic distributed functions running on a fault-tolerant network. According to the requirements of robust partitioning, safety and acceptance data of evidence for IMA platform in integrated modular development guidance and certification consideration RTCADO-297 standard, the IMA platform partition analysis is studied in this paper, whose key points include the IMA platform and its general processing module (GPM), ARINC664 switch and remote data concentrator (RDC). The strategy and objective of the partition analysis for each item are provided to confirm the activities required for each task, which can supply sufficient evidence for robust partitioning analysis, potential risks mitigation, safety analysis and the acceptance of the IMA platform and its items.
Keywords:IMA platform  partition analysis  general processing module(GPM)  ARINC664 switch  remote data concentrator(RDC)
