基于USB接口的数据采集卡在UHT纸盒奶检测仪中的应用

The Application of DAQ Card with USB Interface in the Detection Device of UHT Tetra Pak Milk

UHT纸盒奶检测仪是基于流体力学的运动原理,利用电子、物理方法设计研制的,适用于不同砖型纸盒包装的超高温灭菌牛奶产品的虚拟检测仪器。本文介绍了在UHT纸盒奶检测仪中,在LabVIEW环境下,如何使用USB接口的数据采集卡,进行数据采集以及控制步进电机。通过试验证明该系统达到了设计要求。

The detection device of UHT Tetra Pak Milk is based on kinematic principle in hydromechanics, electronical and physical method ,which is a virtual instrument. It can be used in different UHT Tetra Pak Milk. This paper introduces how to collect data and control the stepping motor using the DAQ card with USB interface in the detection device with LabVIEW environment. The system match with the request of design in the test.
