摘要
在现代工业生产设备中,位移测量器的作用日益凸显,传统的设备往往难以满足现代设备对其体积精度等各方面的高要求。设计了一种基于LabVIEW的霍尔传感器位移测量系统。首先通过分析霍尔传感器的输出特性得到其输出电压与外部位移的关系,再利用外围硬件电路对采集到的输出电压进行放大并滤波,进而根据实测传感器的输出电压计算得出实际的位移值,最后在Multisim中利用压控电压源建立霍尔传感器模型,并利用LabVIEW与Multisim的联合仿真处理来自传感器的输出数据。最终结果表明该系统能有效显示位移并依据设定的限值适时报警。
In modern industrial production equipment,the role of displacement measurement device is traditional equipment is often difficult to meet the requirements of modern equipment on its volume accuracy and other aspects. In this paper,a disp）lacement measurement system based on LabVIEW for Holzer sensor is introduced. Firstly,through the analysis of output characteristics of Holzer sensor, the ralationship between the output voltage and the external displacement is obtained. Secondly, using the peripheral hardware circuit to amplify and filter the output voltage collected,it have been drawn the displaccment calculation accosensor,s output voltage. Finally,using voltage controlled voltage source in Multisim,Holzer sensor model is established. And using the com-bined simulation of LabVIEW and Multisim to process the output data from sensors. The results effectively and timely alarm according to the set timit.
