笔者首先对复杂矿冶装备机内测试(Built In Test,BIT)虚警现象的产生原因进行了分析,并根据故障预测与健康管理(Prognostics and Health Management,PHM)相关理论,构建矿冶装备的三级应急响应预警机制。通过建立BIT降虚警风险数学模型算法,对BIT监测数据进行降低虚警处理,在此基础上得出BIT诊断决策结论,启动相应的自主保障程序,由此证明了该方法可为降低BIT虚警提供了一种解决途径。
The author first analyzes the causes of false alarm in built-in test (BIT) of complex mining and metallurgy equipment, and constructs a new method based on the theories of fault prediction and Prognostics and Health Management (PHM) Three emergency response early warning mechanism. By setting up the BIT drop false alarm risk mathematical model algorithm, the BIT monitoring data is reduced and the false alarms are processed. Based on this, the conclusion of BIT diagnosis and decision-making is obtained and the corresponding autonomous protection procedure is started. It proves that this method can reduce the BIT virtual Police provide a solution.
