基于虚拟仪器双通道无线数据传输系统设计

由于虚拟仪器技术突破了传统电子仪器技术以硬件为主体的模式，能充分利用计算机的硬件资源完成许多传统电子仪器达不到的功能，因此日益受到人们的关注。本文介绍了一种利用PC机声卡和图形化编程语言LabVIEW设计的基于虚拟仪器的双通道元线数据传输系统。该系统可实现音频范围内数据的实时采集、存储、分析及显示。实验结果表明，整个系统成本低、控制容易、采样精度高、使用灵活方便。

Virtual Instrument Based on Dual-Channel Wireless Data Transmission System

The virtual instrument technology changes the model of the traditional electronic instrument technology based on the hardware for it can fully use the hardware resources to complete the functions which can not be realized by the traditional instruments. This paper is about the design of dual channel wireless data transmission system, which is based on sound card of PC and Graphical Programming Language --- LabVIEW. The system can realize real--time data collection, data storage, real and none--real time data analysis and data display. It can be used in all the fields that need audio signals. The results show that the data collection system has characters of low--cost, high sampling precision, convenient and flexible application.
