一种基于二叉树的测控设备故障诊断方法

针对传统故障树知识规则存储和诊断推理算法不易实现的问题，提出了一种基于二叉树的故障诊断方法。首先，通过对故障树与二叉树转换规则与方法的分析，直接构建出测控设备故障二叉树集；然后，利用二叉树节点左右编码值来定位该节点的方法，建立故障诊断规则库；最后，采用遍历诊断规则库的搜索算法实现对故障定位。在测控设备中的应用表明，该方法能够方便地建立诊断规则库，准确定位设备故障，可有效提高设备故障诊断效率。

A fault diagnosis method for TT&C equipment based on binary tree

To solve the difficulties in achieving the fault diagnosis rule’ s store and reasoning algorithm by traditional fault tree,a new fault diagnosis method based on binary tree is proposed. Firstly,a set of fault bi-nary tree for the space Telemetry,Tracking,and Command( TT&C) equipment is directly constructed after analyzing the conversion rule and method for fault tree to binary tree. Secondly,the rule-base for fault diag-nosis is set up by the method,in which the node’ s left and right coding values are used to locate tree’ s node. Finally,the fault location is realized by the searching algorithm based on tranversing the diagnosis rule-base. The application in TT&C equipment shows that this method can easily establish diagnosis rule-base,accurately locate equipment faults and effectively improve the efficiency of fault diagnosis.
