摘　　要：采用层级BIT设计架构,建立了操作系统层与应用层BIT交互的接口模型。按照BIT不同的分类依次设计不同类型的BIT测试项,在基于ARINC653标准AcoreOS653操作系统下实现并验证设计的相关BIT测试项。通过研究证明了在层级BIT架构下设计出的BIT测试项,根据不同测试项引发故障严重程度的不同合理设计不同的故障阈值,既保证了较高的故障检出率,又降低了故障误报的风险。The interface model of BIT interaction between operating system layer and application layer is established by using hierarchical BIT design architecture.Different type of BIT test items are designed according to different categories of BIT.Relevant BIT test items designed are implemented and verified in AcoreOS653 operating system based on ARINC653 standard.Through the research,it is proved that the BIT test items designed under the hierarchical BIT architecture can reasonably design different fault thresholds according to the different fault severity caused by different test items,which not only ensures high fault detection rate,but also reduces the risk of false alarm.
