It indicates that LabVIEW is usually used in the task of normal data acquisition 、test、measurement and so on . At the same time, it can reduce systematic construction period and improved programming efficiency too. Combining LabVIEW with the measurement and control technology of the puter I finish the experiment of the measurement and control of the DC motor position in the experiment platform.
