摘要 针对车地无线通信设备故障诊断信息不一致的情况下进行故障的推理和诊断,提出了一种基于粗集理论的车地无线通信装备故障诊断方法。该方法从诊断决策支持系统定义出发,将车地无线通信设备故障诊断问题用一个不同简化层次的故障决策网络表示,由网络节点根据定义出的规则置信度和覆盖度可推导出对应有效的故障诊断规则集合。通过故障诊断规则匹配,便可方便得出车地通信单元故障诊断结果,实例分析表明该方法具有较好诊断有效性。

英文摘要 In order to make reasoning and decision under the condition of inconsistent fault diagnosis information, this paper presented a fault diagnosis method for train-ground wireless communication unit of communication based train control (CBTC) based on rough set theory. According to the definition of fault diagnosis decision system, constructed a decision network with different reduced levels to denote the fault diagnosis problems of the train-ground wireless communication (TGWC) unit by way of the definition of the rule confidence and coverage degree. Results show that the diagnosis model can provide high diagnosis validity of different fault types just only through the fault diagnosis rules match.
