The research and application of the load - control system were studied in this article 本文主要論述了球磨機負荷控制系統(tǒng)數(shù)學模型的建立與應用。
According to the results of the analysis and the experiment , the mathematic model of the ball mill load - control apparatus was established and its sample was successfully designed 根據(jù)多次試驗和分析結果,建立了球磨機負荷控制系統(tǒng)的數(shù)學模型,也完成了其樣機的設計。
Because the traditional control method that was based on the temperature and pressure difference cannot achieve this aim , so in this project , the mathematic model of the load - control system was established mainly based on the ball mill ' s sound and its sample was designed 本文主要根據(jù)磨音來建立球磨機負荷控制系統(tǒng)的數(shù)學模型,并且進行了球磨機負荷控制儀樣機的設計。
The ball mill load - control apparatus adopted the assembly language and the c51 language to program and its concerned software was designed , including the data collection , the wave - percolation , the short - time average over - zero ratio , the estimation of the power chart and the average - period chart 磨機負荷控制儀軟件使用匯編和c51編程,本文進行了相關軟件的設計,包括數(shù)據(jù)采集、濾波、短時平均過零率、功率譜估計和平均周期圖等。
It was demonstrated that this sort of load - control apparatus has superior performance . we used a electric transmitter as the transducer to collect the sound signal , using the daq toolbox of the matlab to achieve the collection of the sound signal , and using the dsp toolbox of the matlab and the sound - launch technology to analyze the time - domain characteristic and the frequency - domain characteristic of the signal , chiefly analyze its short - time average amplitude , its short - time over - zero ratio and its estimate of the power chart and the average - period chart 實驗中使用了駐極體話筒作為球磨機聲音拾取傳感器,利用matlab中的數(shù)據(jù)采集( daq )工具箱實現(xiàn)對磨音的采集,利用matlab信號分析( dsp )工具箱和聲發(fā)射技術對磨音進行時域和頻域分析,主要分析磨音的短時平均幅度和能量、短時平均過零率、功率譜估計和平均周期圖。
