摘要:随着科学技术的飞速发展,异步电动机在众多行业领域得到广泛推广。尽管异步电动机广泛推广提升了产业效率,促进了社会发展,但其实际应用中会出现各式各样的故障,对人们人身安全构成极大威胁。本文首先阐述了数据融合的内涵特征,其次探讨了异步电动机常见故障,最后论述了数据融合下的异步电动机故障诊断,以供参考。
Abstract: With the rapid development of science and technology, asynchronous motors have been widely promoted in many industries. The wide promotion of landscape asynchronous motors has improved industrial efficiency and promoted social development, but various failures will occur in their practical applications, posing a great threat to people's personal safety. This article first expounds the connotative characteristics of data fusion, then discusses the common faults of asynchronous motors, and finally discusses the fault diagnosis of asynchronous motors under data fusion for reference.

现如今,异步电动机已在众多行业领域得到广泛推广,一旦引发故障,将造成难以估量的经济损失,这让异步电动机故障诊断技术成为广大业界人士研究的重要课题。对于异步电动机的故障诊断,传统诊断方法主要依托单一的故障特征、诊断方法开展,而因为异步電动机结构复杂,引发故障的因素多种多样,电动机在诊断时存在一系列不确定因素,凭借单参数诊断获取的结论并不可靠,诊断结果可信度不足[1]。为此,本文将对数据融合下的异步电动机故障诊断进行思考研究。
1 数据融合概述
数据融合,亦可称之为信息融合,主要指的是依托计算机技术,对按照时序获取的多个传感器或者多源的信息在相应标准下开展综合处理,进一步获取准确可靠结论的信息处理过程。从广义层面而言,数据融合涉及通信、信号处理、模式识别、神经网络、人工智能等多个领域,而数据融合应用的信息技术及处理手段都源自该部分领域。……
