中文摘要: 为提高矿井风速测量中设备测量精度,本文应用自行设计的风速测定校正系统,测试出不同风速准确值及热敏风表读数值,同时应用回归分析的方式得出热敏风表测量值与风速准确值间关系,确定风表读数的修正参数,并进一步试验对修正参数进行试验验证,试验结果显示该修正参数可有效提高风速测定精度。

Abstract:In this paper,in order to improve the accuracy of equipment measurement in mine wind speed measurement, the self-designed wind speed measurement and correction system were used to determine the accurate values of different wind speeds and the reading values of thermal anemometers. At the same time, the relationship between the measured values of thermal anemometers and the accurate values of wind speeds was obtained by regression analysis, and the revised parameters of the reading values of wind meters were determined. Further tests were carried out to verify the revised parameters. The results show that the corrected parameters can effectively improve the accuracy of wind speed measurement.
