摘　　要：为了更及时地发现并解决嵌入式操作系统中发生的故障,设计并实现了一种基于国产嵌入式操作系统的故障监测系统。该系统主要由核心硬件失效监测、软件故障监测及日志管理三大模块构成。该系统通过监测功能发现故障,利用诊断功能分析故障,通过日志管理功能存储故障信息,最后调用故障处理功能处理故障并打印故障信息。测试结果表明,系统可快速监测到故障发生并诊断出正确的故障信息,使用人员获取到故障信息后即可对故障原因进行分析并对故障进行定位,从而方便地处理故障。In order to find and solve the faults in embedded operating system more timely,a fault monitoring system based on domestic embedded operating system is designed and implemented in this paper.The system is mainly composed of three modules:core hardware failure monitoring,software fault monitoring and log management.The system finds the fault through the monitoring function,uses the diagnosis function to analyze the fault,stores the fault information through the log management function,and finally calls the fault handling function to deal with the fault and print the fault information.The test results show that the system can quickly detect the occurrence of the fault and diagnose the correct fault information.After obtaining the fault information,the users can analyze the cause of the fault and locate the fault,so as to solve the fault conveniently.
