摘　　要：为提高大型复杂装备故障诊断的准确率和效率,提出了一种智能化故障诊断方法。该方法以粗糙集理论为基础,实现信号采集位置优化和特征值约简,应用信息融合技术将振动和噪声信号融合诊断,通过人工神经网络进行故障模式分类,以柴油机为例,验证了方法的正确性和有效性。In order to improve fault diagnosis accuracy and efficiency of large and complex equipment, proposed an intelligent fault diagnosis method. The method is based on rough set theory, can optimize monitoring location and domain values. The application of information fusion technology will diagnose vibration and noise signal integration. Fault diagnosis can be achieved by artificial neural network. Take diesel engines for example, the process verified correctness and effectiveness of method.
