摘要
在LabVIEW测量程序中嵌入数据剔除功能,可提高测量结果的准确度。通过比较不同的数据剔除准则可知,当检验数据量n较小时(n<100),采用格拉布斯准则剔除含粗大误差的数据较为合适。根据格拉布斯准则,在LabVIEW中实现数据剔除的功能,并以超声波测距为例,说明数据剔除功能对改善测量结果的作用。
Embedded data rejecting function in the Lab VIEW measuring procedure can improve the accuracy of the measurement results.By comparing different data rejecting criterias,it is more suitable to use the Grubbs criterion to reject datum contained careless error when the amount of test data is small（n 100）.In accordance with Grubbs criterion,a data rejecting function has been achieved in Lab VIEW.Ultrasonic ranging is described as an example to illustrate the effect of data rejecting function on improving the measurement results.
