数据不平衡分布下燃气调压器故障识别方法

Zhendong Ceshi yu Zhenduan
针对燃气调压器故障识别中不平衡数据影响模型识别能力的问题，提出一种一维卷积神经网络（one‑dimensional convolutional neural network，简称1D‑CNN）与注意力机制（squeeze‑and‑excitation，简称SE）相结合的改进深度卷积神经网络（SE‑1DCNN）方法。首先，使用一维卷积核提取故障特征；其次，在交替的卷积层后添加SE模块用于通道加权，选择性地保留所需的重要信息特征，并抑制弱相关的特征；最后 ...

基于优化EIF的大型望远镜非预期故障诊断

Zhendong Ceshi yu Zhenduan
针对极端环境下的大型望远镜会面临各种无法提前预测的故障和异常情况，提出一种基于优化扩展孤立森林（extended isolation forest，简称EIF）的非预期故障诊断方法。首先，通过特征选择算法ReliefF和最大相关最小冗余（maximum relevance and minimum redundancy，简称mRMR）算法对原始数据集进行特征优选；其次，采用蜣螂优化算法（dung beetle optimizer，简称DBO）为EIF算法选择合适参数，构建最佳故障诊断模型；最后 ...
