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。
Based on the robust zoning features of the Integrated Modular Avionics (IMA) platform, the IMA platform must be able to provide robust zoning and other protection for resident and resident functions that allow multiple resident Application sharing a platform and platform resources, and its own resources to support system-level distribution function in the fault-tolerant network to run. According to the development guide and certification of integrated modular avionics system, considering the requirements of the RTCA DO-297 standard on the robustness of IMA platform zoning, security and certification data, this paper studies the IMA platform zoning analysis, focusing on the IMA platform and its components General Processing Module (GPM), ARINC664 airlines data network and remote data concentrator (RDC). Give each component’s partition analysis strategy and goals, identify the activities to be performed on each mission, and provide sufficient evidence for robustness analysis of the IMA platform and its components, mitigation of potential risks, security analysis, and endorsement.
