一种基于控制流的复杂系统故障树自动建树方法

A Method Based on Control Stream of Complex System to Fault Tree Auto-constructed

复杂系统中故障以控制流的形式传递,其输出变量偏差于正常输出变量可用不同的控制流描述,根据控制流进行故障树的自动建立,可设计四个模块将变量传递关系用数据表示出来。首先,定义各种数据结构把控制系统中各种变量量化在具体的数据当中,然后通过识别控制环算法和故障树自动建树算法建树,最后,把连接好的故障树数据转化为二叉树数据结构,用可视化语言把故障树显现出来。

The fault transfers in complex system by way of control streams. It depicts the falsification between input variables and output variables in different control streams. Based on control stream, it designs four models to realize the transfer of variable. First, it defines the data structures, makes the variables into exact data. On the other hand, it uses auto- recognise control cycle algorithm and tree auto- constructed algorithm. In the end it transfers the data of fault tree into bintree data construction. Then,it uses visual language to make the fault tree to visualize.
