Flex下的虚拟仪器控件设计和应用

利用富互联网技术表现力更强的优势,采用Flex语言设计了一组虚拟仪器控件,以便于将富互联网应用技术拓展到网络化测控、设备远程监测、虚拟实验等领域.介绍了Flex下虚拟仪器控件的设计方法和在Flex集成开发环境下的调用方法,并给出了一个富互联网应用模式的声音信号采集和分析虚拟实验的应用实例.

Design and Application of Virtual Instrument Control in Flex

Compared with the traditional techniques,the rich Internet applications(RIA)has the great advantage on the expression.In order to expand its application to the fields such as networked measurement and control,equipment remote monitoring,virtual experiment,etc.,a set of virtual instrument controls are designed with the Flex language.The design process and encapsulation method of the Flex-based VI controls,and its call method in the Flex Builder IDE are introduced.Finally,a RIA-based application of virtual experiment for sound signal acquisition and analysis demonstrates the correctness of research ideas.
