摘要
针对主通风机故障对煤矿安全生产构成的威胁,综合采用主分量分析和小波分析方法对主通风机进行故障诊断。论述了主分量分析和小波分析原理,建立了主通风机故障诊断数据处理模型。在此基础上利用Matlab对采集的振动信号进行仿真实验,结果表明:该方法能够准确判断煤矿主通风机的故障类型。
In view of the main ventilator breakdown which threats the coal mine production safety, uses the main component analysis and the wavelet analysis method for fault diagnosis to the main ventilator. Elaborated the main component analysis and the wavelet analysis principle, has established the main ventilator failure diagnosis data processing model. Based on this carries on the simulation experiment using Matlab to the gathering vibration signal, the results show that this method can judge the coal mine main ventilator breakdown type accurately.
