中文摘要：

对基于LabVIEW的USB数据传输技术进行了研究。介绍了一种以PHILIPS公司的USB接口芯片PDIUSBD12为核心组成的USB接口电路；并介绍了该接口电路的固件编程方法；详细介绍了基于LabVIEW的应用程序的具体实现方法。通过数据传输的测试表明，采用LabVIEW和USB接口可以很好地实现上位主机和下位从机之间的数据传输。

英文摘要：

The USB data transmission technology based on LabVIEW was studied. The USB interface circuit which core chip is PDIUSBD12 produced by PHILIPS, the firmware programming method of the USB interface circuit, and the specific method of compiling application which is based on the LabVIEW were introduced. The resuh in the data transmission test shows that it can realize the data transmission between superior monitor and inferior computer by using LabVIEW and USB interface.
