基于LabVIEW与Multisim的电路实验平台设计

Design of Circuit Experiment Platform Based on LabVIEW and Multisim

该文利用LabVIEW与Multisim的联合仿真功能,实现电路参数的实时修改,可在LabVIEW的前面板中观察到更加直观的实验现象,进行实验数据的采集与保存。结合LabVIEW的网络通信功能,构建了基于B/S架构的远程虚拟电路实验室,可以从远端进行实验、获取数据、观察实验现象。同时结合NI ELVIS实验平台开发了硬件电路实验与实验室环境监控平台,实现了基于Web的远程可视化测控并用于远程教学,缩短了实验时间,提高了实验设备的利用率,对于高校的实验教学改革具有重要的借鉴意义。

By taking advantage of the LabVIEW-Muhisim co-simulation toolkit ,it is possible to alter the parameter of circuit,observe a more vivid experimental phenomenon and gather experimental data. Combine the network communica- tion function of LabVIEW,this article build a remote virtual laboratory based on B/S framework,which can conduct an experiment from the remote terminal,get experimental data,observe the phenomenon. At the same time using the NI ELVIS experiment to build a hardware circuit and environment detection platform,achieving the visualization of measure- ment and control and its application on experiment teaching can cut down the testing time,improve the use efficiency of equipment,which have an important reference for the revolution of experiment teaching in colleges and universities.
