摘要

提出设计一款基于LabVIEW和ARM的虚实结合模拟电路实验平台。本实验平台包括上位机进行的虚拟仿真和实际电路实验平台两个部分。首先通过LabVIEW与Multisim联合仿真获取实验参数,通过串口传输给下位机实验箱改变相应实际电路参数,以达到实验参数联调的目的;将下位机实验波形结果采集到上位机,并调用Multisim仿真结果实现实验结果在LabVIEW界面共同显示,以达到虚实结合的模拟电路实验平台的设计。经测试,该平台可以随地实时稳定运行,有效缩短了实验时间,提高了实验效率,使模拟电子电路实验不再局限于实验室等物理条件要求,有较强的教学意义。
        In the paper,a virtual-real analog circuit experimental platform based on LabVIEW and ARM is proposed.The experimental platform includes two parts:virtual simulation and actual circuit experimental platform.Firstly,the experimental parameters are obtained by LabVIEW and Multisim joint simulation,and the corresponding actual circuit parameters are changed through serial port transmission to the lower computer experimental box to achieve the purpose of experimental parameters debugging.The lower computer experimental waveform results are collected to the upper computer,and the Multisim simulation results are invoked to achieve the experimental results in the LabVIEW interface to display the experimental results together,so as to achieve the level of virtual-real simulation circuit experiment.The test results show that the platform can run stably in real time anywhere,shorten the experimental time effectively,improve the experimental efficiency,so that the experiment is no longer confined to physical conditions such as laboratory requirements,and has a strong teaching significance.
