基于虚拟仪器的移动互联开放实验室探索

Research and Realization of an Open Laboratory of Mobile Internet Based on Virtual Instrument

针对工科实验设备昂贵,实验场所和开放时间固定等问题,提出了一种基于Data Dashboard,LabVIEW和Matlab构建移动互联开放实验室的方法,该方式利用LabVIEW构建专业实验服务器,结合LabVIEW与Matlab混合编程技术实现实验仿真,移动终端使用Data Dashboard提交实验参数和观察实验结果,并给出通信原理幅度调制实验仿真实例。实验结果表明该方法能够让学生实现移动学习,老师可以根据教学需要制定实验内容,能够节约大量仪器设备经费投入,也能让学生自由安排时间和地点进行专业实验,有很好的价值和应用前景。

According to problem during experiment teaching in engineering such as the expensive devices,fixation of experimental sites and open time. A method of building a novel mobile Internet open laboratory was proposed in this study. The method is based on Data Dashboard,Lab VIEW and Matlab. Lab VIEW is used to construct a professional webserver. The simulation is realized by utilization of programming technique mixed Lab VIEW and Matlab. Mobile terminals are applied to submit the parameters and observe the results by Data Dashboard. The experimental simulation of communication principle amplitude modulation is given. In this study,the method was applied experimentally in the communication principle experiment teaching for undergraduates. And the experimental results showed that the students can study movably and the teacher can set up the experimental contents according to the content of the teaching through the new method. This method not only can save a large amount of equipment and equipment investment,but also allows students to freely arrange the time and place for professional experiments. As a result,the new method has an important research value and a wide application prospect.
