针对现有湿法冶金工艺机制复杂和浸出工艺故障诊断方法存在精度较差等问题,研究了用改进的动态因果图诊断湿法冶金浸出工艺故障,主要通过二元区间数对动态因果图进行优化改进,并对条件概率上下限进行加权,实现湿法冶金浸出工艺故障诊断.结果表明:该故障诊断方法相较于常规方法,故障诊断准确率更高,能对浸出工艺的故障进行较准确的诊断.
Fault Diagnosis Method for Hydrometallurgical Leaching Process Based on Improved Dynamic Causal Diagram
Aiming at the complexity of existing hydrometallurgical process mechanism and the poor accuracy of existing leaching process fault diagnosis methods,an improved dynamic causal diagram was studied to diagnose hydrometallurgical leaching process faults.The dynamic causal diagram was optimized and improved mainly by binary interval number,and the upper and lower limit of conditional probability were weighted to realize the fault diagnosis of hydrometallurgical leaching process.The results show that the fault diagnosis method is more accurate than the conventional method,and can diagnose the faults of leaching process more accurately.
