摘要

目前

磨煤机试验方法仍沿用手动现场采集数据再输入Excel处理的测量方法

该方法存在采集数据周期长、误差大、数据量有限等不足。本文通过对Lab VIEW开发平台深入分析

结合磨煤机试验原理及数据处理方法

开发了基于Lab VIEW的磨煤机试验数据在线采集处理软件

并对某机组的磨煤机出口风速调平和入口风量系数标定进行软件仿真测试。结果表明:本文软件计算结果与原手动采集Excel计算结果相同;本文软件系统在线采集计算试验耗时为手动采集Excel计算的0.075倍

软件采集数据量为手动采集数据量的503.3倍。该软件系统为磨煤机的智能控制提供了技术支持。

Abstract

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.
