BIT综合表示模型研究

Study on Model for BIT Integrated Expression

在分析机内测试(BIT)主要设计要素组成的基础上,提出了BIT综合表示模型。建立了BIT综合表示模型的数学定义,包括BIT单元模型、BIT层次关系集合、BIT数据传送方式集合、BIT执行次序集合和BIT综合表示模型。在数学定义的基础上,进一步建立了BIT综合表示的框图模型和表格模型,这两种模型可以直接用于工程分析。最后,以某辅助导航系统为案例,进行了BIT综合表示模型的应用,给出了框图模型结果和表格模型结果,验证了该模型的可用性和有效性。

A model for built-in test （BIT） integrated expression is presented based on the composition analysis of its main design elements.Mathematical definitions of the model are established,including the BIT unit model,the set of BIT hierarchy relations,the set of BIT data transmission modes,the set of BIT execution orders and the model for BIT integrated expression.A block diagram model and a table model for the BIT integrated expression are also proposed based on the mathematical definitions,and these two models can be directly used in engineering analysis.Finally,the model for BIT integrated expression is applied to the case of an aided navigation system.Both the block diagram model result and the table model result are provided,which serve to show the availability and validity of the model.
