摘　　要：本文简要介绍了一个GBIP自动测试系统 ,用于采集激光测径仪在各种干扰条件下的测量信号 ,并通过对受灰尘、纤维干扰的测量信号和标准测量信号的处理及其分析 ,找出尘埃、纤维干扰在时域和频域的表现 ,得出此种干扰对测量直径的影响。In this article the author have inroduced a auto-testing system which was based on GBIP(General Purpose Interface Bus).This system is used to gather signal of laser dia-testing machine in each disturb condition.And through the disposal and analyse to each signal contrasted with the standard signal,we can find out the characteristic of dust and fibrin disturb in time-field and frequency-field.Then deduce this disturb's affection to measure the diameter.
