摘　　要：给出了机载综合核心处理系统AICPS的软件结构和组成,采用基于TLS三层栈的先进的航电系统结构,其通用系统管理GSM分为健康监控、故障管理和配置管理三个软件功能模块,以及飞机级、综合区级、资源元素级共三级。基于GSM和运行蓝图,论述了AICPS的故障管理技术和容错重构机制,重对故障处理的过程如故障检测、故障诊断、故障处理和配置管理进行了讨论。由于航空电子系统高安全、高可靠性等特点,作为提高可靠性的手段之一,研究故障管理与容错重构非常必要。This paper introduces the software architecture and components of airborne real- time integrated core processing system （AICPS） for new generation avionics system. Adopting advanced avionics system architecture based on three- layer stack（TLS）, the general system management（GSM） of the architecture is divided into three software function modules including healthy management （ HM）, fault management （ FM ） and configuration Management （ CM ）, and is divided into aircraft level, integrated section level and resource element level. Based on GSM and running blueprint, fault management techniques and fault- tolerant reconfiguration mechanism of AICPS are described and fault- processing processes such as fault detects, fault diagnoses and fault processing and configuration managements are discussed mainly. As for high security and high reliability of avionics system, the research of fault managements and fault- tolerant reeonfigurations is very significant for raising its reliability.
