摘要
结合虚拟仪器多参量数据采集系统的软件设计,简述虚拟仪器技术的基本概念、LabWindows/CVI的功能与特点,重点介绍数据采集卡的驱动、虚拟仪器软件的开发方法和实现技术,并给出多路信号数据采集程序实例。利用标准信号及实验信号对所设计的系统进行测试,通过实验调试,结果显示软件工作正常。
With reference to the software design of multi-parameter data acquisition system based on virtual instrument,this paper introduces the basic concept of virtual instrument,the functions,and the characteristics.It is emphatically demonstrated how to drive the data acquisition card,the virtual instrument software development method,and the implementation technique.A multi-parameter data acquisition process is given as an example.The test is carried out in the designed system with standard signal and the signal from experiments.The result shows that the software works efficiently,and the target of the design is achieved.
