基于USB数据采集技术的远程虚拟测试系统

Remote virtual measurement system based on USB data collection technology

为适应网络化测试成为测试技术的发展方向,将虚拟仪器技术与USB接口技术相结合,USB总线可以实现对数据实时高速的采集,把采集数据传送到主机后再通过LabVIEW的网络通信功能进行数据的远程传输,通过USB接口模块硬件和软件的设计方法,阐述了LabVIEW开发平台上网络化传输的实现方法。

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.
