Abstract

本发明公开了一种多元信息融合的发电厂电气设备分类与异常检测方法。所述方法包括以下步骤：获取电气设备的多元信息；判断电气设备所处的状态；预置声音传感器获取电气设备运行的音频；通过训练好的深度神经网络进行状态识别，得到状态识别置信度分数；若状态识别置信度≤置信度阈值，则认为电气设备存在故障，否则完成电气设备状态声音分类；通过训练好的深度神经网络进行已知故障异常识别，得到故障识别置信度分数；若故障识别置信度分数≤置信度阈值，则认为电气设备存在未知故障，否则完成电气设备已知故障异常识别；进行电气设备未知故障识别，并作为新异常样本加入电气设备故障声音样本库。本发明解决了目前算法存在的问题。
