Abstract: New generation of avionics system is highly integrated and modularized, highly safety operation system must be supported, and health monitor technology plays great part in the security and reliability of the system. This paper studies the health monitoring mechanism in an embedded Real Time Operation System(RTOS), and describes the critical part of the health monitor: error diagnosis, error injection, error response, error recovery.

Key words: embedded RTOS, health monitor, ARINC653 standard, temporal and spatial segregate

摘要： 在高度综合化、模块化的新一代航空电子系统中，高安全的实时操作系统和健康监控技术对提高系统的安全性、可靠性方面起了重用的作用。该文对一种嵌入式实时系统的健康性监控机制的设计原理进行了研究，讨论了错误诊断、错误注入、错误响应、错误恢复等健康监控技术关键点。
