摘　　要：针对机载嵌入式计算机系统自检测容易造成系统运行不稳定等问题,提出了基于故障配置的自检测设计方法,通过离线配置的方式对系统运行各阶段的故障检测内容、编码、故障记录及响应模式进行静态配置。检测软件根据配置信息自动开展系统自检测,满足了机载计算机自检测的低延迟、高可靠、快速配置等需求。通过配置信息对检测时长进行的可控调节,消除了分区及任务超时造成系统运行的不稳定因素。相比于传统的自检测方法,具有配置灵活、与应用软件无关等优点。Since self-detection is likely to cause the system unstable for airborne embedded computer system,a self-detection design method is proposed based on fault configuration,by way of offline configuration to configure the fault detection,coding,fault record and response model by static configuration in every process when system is running.Detection software starts to execute self-detection according to the configuration information.It meets the requirements of low latency,high reliability and fast configuration of airborne computer self-detection.By controlling the detection time through configuration information,the unstable factors of system operation caused by partition and task timeout are eliminated.Compared with the traditional self-detection method,it has the advantages of flexible configuration and independent to application software.
