摘要
由于传统实验不能有效满足学生实验的要求,根据课程标准需要,基于Lab Windows/CVI软件开发平台设计了一套虚拟仪器实验系统。它主要由PXI机箱、信号转接盒、实验电路板以及电缆等组成,能够实现模拟信号采集/输出、电机转速测量、温度测试、串口调试等多种实验项目。最后以光电传感器测量直流电机转速为例,重点介绍了实验的实现方法。该系统具有结构简单、功能强大、扩展性强等优点,应用前景良好。
Because the traditional experiments can＇t effectively satisfy students＇ requirement,according to requirements of course standard,a virtual instrument experiment system is designed based on Lab Windows/CVI software development platform. This experiment system is composed of PXI chassis,signal switching box,experiment circuit board and cables etc. It can realize many experiments such as collection or output of analog signals,measurement of generator＇s rotational speed,measurement of temperature,debugging of serial port etc. Finally,this paper takes measurement on the rotational speed of the direct current generator by the photoelectric sensor as the example,and focuses on realization of the experiment. This system possesses the merits such as simple structure,big function,strong extensibility and etc.,therefore it has good foreground.
