實驗教學(xué)一直是工科教學(xué)中不可或缺的組成部分,對培養(yǎng)學(xué)生的動手能力,獨立思考能力,創(chuàng)新思維與發(fā)散思維具有重要的作用。針對目前電路教學(xué)實驗中電路仿真實驗與實物電路實驗各自獨立,無法統(tǒng)一問題,提出將仿真電路實驗與實物電路實驗有機的結(jié)合同步操作,并使用Web發(fā)布實現(xiàn)遠程實驗操作。采用Multisim作為電路實驗仿真平臺,NI Eiviss II作為實物電路實驗硬件平臺,運用LabVIEW整合Multisim電路仿真實驗與實物電路實驗,實現(xiàn)仿真與實物實驗有機結(jié)合,兩種實驗可同步進行。學(xué)生在仿真實驗中先可探索實驗,然后做實物實驗。同時運用LabVIEW開發(fā)出實驗過程人機交互操作接口界面,使用過程中效果良好。Experimental teaching has always been an indispensable part of engineering education.And it always plays an important role in cultivating students'practical ability,independent thinking ability,innovative thinking and divergent thinking.But simulation experiment and physical experiment cannot be unified in the circuit teaching experiment at present.In order to solve this problem,this paper proposes to combine organically the simulation circuit experiment with physical circuit experiment,and synchronously operate them.This paper uses the WEB publishing to achieve remote experimental operation.Multisim is used as the circuit simulation platform,and NI Eiviss II is used as the physical circuit hardware platform.Multisim circuit simulation experiment and physical circuit experiment are implemented by LabVIEW to Realize the combination of simulation experiment and physical experiment.Students do explore experiments in simulation experiment firstly,and then do physical experiment.And this paper uses LabVIEW to develop the experimental man-machine interface.
