基于LabVIEW的信号与系统实验平台的关键技术

Key Technologies of Signal and System Experimentation Platform Based on LabVIEW

针对当前高校实验教学的现状,提出构建基于LabVIEW的信号与系统实验平台,介绍了系统的整体构架,和利用DataSocket进行信号的实时传输,以及数据存储、数据回放、试验人员信息登记、独立应用程序生成等关键技术的实现方法.该平台可以完成谱分析、相关分析等多种典型试验,使实验教学更加灵活方便.

In view of the actuality of experimentation teaching in colleges and universities, an＇ experimentation platform based on LabVIEW for Signal and System is presented, and then the main structure of it is introduced briefly, finally the realization methods of some key points are proposed, such as the real-time data transmission with DataSocket, data storage, data redisplay, registration of experimentalists, building application programme and so on. Typical experiments such as spectral analysis and correlation analysis can be done on this platform, which makes experimentation teaching flexible and convenient.
