摘要
声卡作为数据采集卡具有价格低廉、开发容易和系统灵活等优点,在给出系统结构的基础上,分析了系统硬件和软件设计技术,对普通软件开发工具、MATLAB和虚拟仪器等三类软件开发工具进行了分析和比较,得出LabVIEW是声卡信号采集系统软件开发工具的首选,并给出一个基于LabVIEW的软件设计实例。实际应用表明:基于声卡的,尤其是声卡与虚拟仪器相结合的信号采集技术具有广阔前景。
Soundcard as a DAQ card has low-price, easy-developing and flexible-system such virtues. The design technologies of hard- ware and software were analyzed after system structure was proposed. Based on the analysis and comparison with three types of software development tools:ordinary software development tools, MATLAB and VI (Virtual Instrument ), can find that LabVIEW is the preferred software developing tool for this system. A software design case with LabVIEW is present then. Through actual applications, it' s shown that the signal acquisition technology based on soundcard,especially combining with VI has broad prospects.
