摘要
将主要用于测控领域的虚拟仪器扩展作为一种通用信号处理平台。以NI的LabVIEW为框架,以NI的数据采集卡为主要硬件设计了一个完整的信号处理平台,在该平台上可以快速构建多种多样的信号处理系统,实现数据的现场采集与处理。此外,针对LabVIEW的一些不足,平台提供了多种编程语言的接口,使用者可以根据需要,选用Matlab,C语言等填写核心算法,从而发挥各种编程语言的优点,增强平台的通用性且丰富了系统的功能。最后,运用该平台搭建了2FSK信号解调系统,验证了该平台的通用性和有效性。
The virtual instrument which is widely used in industrial measurement and control is applied as a common signal processing platform. A perfect signal processing platform which takes LabVIEW as the framework, and a data acquisition card as the main hardware is designed. Various kinds of field signal processing systems can be quickly built on this platform to realize the real-time data acquisition and processing. Considering the deficiency of LabVIEW, various kinds of program lan- guages such as Matlab or C are supported by this platform. The hybrid programming can take advantage of each program language, which enhances the compatibility and the functions of this platform. A 2FSK demodulation system was successfully built to demonstrate the compatibility and effectiveness of this platform.
