Abstract
Networked measurement is the development direction of the measuring and testing techniques.The combination of virtual instrument technology and USB interface technology meets the trend.USB bus can be used to collect real-time data at high speed and transfer to the host PC.The data then can be transferred remotely with the network function of LabVIEW,the paper introduces the methods to design the hardware and software of the USB interface module.The implementation approach of network transmission with LabVIEW is set forth.
