A virtual instrument system is proposed to test the performance parameters oflocal-ventilator installed under coal mines,which can do ventilator parameter acquisition automatically,as well as plot and analyze the ventilator performance curve.The whole system is designed using the virtual instrument technology combined with network technology based on Labview platform.Experimental results show that it can monitor and evaluate ventilators performance parameters automatically and efficiently,which provides critical information for ventilator safety under coal mine.
