At present

the coal mill test method is still based on entering the manual data collected on the site to Excel processing. This method has some problems such as long data acquisition period

large error and limited amount of data. Through deep analysis of Lab VIEW development platform

combined with coal mill test principle and data processing methods

this study develops an online collection and analysis system software for coal mill test data based on Lab VIEW. Moreove

this software is used for the mill outlet air speed leveling and inlet air volume coefficient on a unit. The test results are the same as those of the original manually collected Excel calculation. The online collection and test calculation time using this software is 0.075 times of that using original manually collected Excel calculation. And the amount of data collected by this software is 503.3 times of that using original manually collected Excel calculation. This software provides technical support for the intelligent control of coal mill.
