【摘要】：高校傳統(tǒng)實(shí)驗(yàn)教學(xué)以組為單位作實(shí)驗(yàn),使部分同學(xué)難以全部參與和投入,沒(méi)能充分了解和掌握實(shí)驗(yàn)全過(guò)程,儀器設(shè)備成本高,而且由于場(chǎng)地及課時(shí)的限制造成實(shí)驗(yàn)室設(shè)備也不能充分利用,最終浪費(fèi)了學(xué)校大量的人力物力,同時(shí)學(xué)生還不能真正地掌握實(shí)驗(yàn),學(xué)習(xí)效率較低�；�于計(jì)算機(jī)技術(shù)的虛擬儀器的引入,不但可以節(jié)約大量?jī)x器設(shè)備的經(jīng)費(fèi)投入,而且更新和調(diào)整的實(shí)驗(yàn)方法和手段使得實(shí)驗(yàn)室的實(shí)驗(yàn)教學(xué)設(shè)備保持其先進(jìn)性,提高了實(shí)驗(yàn)教學(xué)和科研的質(zhì)量與效率,是實(shí)驗(yàn)教學(xué)的一個(gè)新的發(fā)展方向,促進(jìn)了實(shí)驗(yàn)室技術(shù)的進(jìn)步。 LabVIEW編程語(yǔ)言靈活、開(kāi)放、用軟件代替了儀器功能,具有良好的用戶界面、操作簡(jiǎn)單等優(yōu)點(diǎn),電工與電子類課程是電類相關(guān)專業(yè)學(xué)生學(xué)習(xí)的一個(gè)重要環(huán)節(jié),課程理論性較強(qiáng),在計(jì)算機(jī)上建立虛擬實(shí)驗(yàn)室,應(yīng)用LabVIEW開(kāi)發(fā)平臺(tái)設(shè)計(jì)的虛擬實(shí)驗(yàn)儀器可以實(shí)現(xiàn)電工電子類課程中常見(jiàn)的實(shí)驗(yàn),包括支路電流法、節(jié)點(diǎn)電壓法、一階動(dòng)態(tài)電路分析、二階動(dòng)態(tài)電路分析、RLC串聯(lián)諧振電路的研究、RC一階的頻率響應(yīng)、3-8線譯碼器、8選1數(shù)據(jù)選擇器、同步二進(jìn)制計(jì)數(shù)器仿真等模塊的設(shè)計(jì),以及基于聲卡的虛擬信號(hào)發(fā)生器設(shè)計(jì)和虛擬示波器的設(shè)計(jì),以此可提高學(xué)生學(xué)習(xí)興趣,彌補(bǔ)了硬件環(huán)境下實(shí)驗(yàn)教學(xué)的不足,改進(jìn)了電工與電子課程實(shí)驗(yàn)教學(xué)的教學(xué)質(zhì)量,提高了教學(xué)效果。
[Abstract]:The traditional experiment teaching in colleges and universities takes the group as the unit to do the experiment, which makes some students difficult to participate and invest fully, fails to fully understand and master the whole process of the experiment, and the cost of the instrument and equipment is high.And because of the limitation of the space and class hours, the laboratory equipment can not be fully utilized, which ultimately wastes a lot of manpower and material resources of the school, and at the same time, the students can not really master the experiment, and the learning efficiency is low.The introduction of virtual instruments based on computer technology can not only save a large amount of equipment investment, but also update and adjust the experimental methods and means to keep the laboratory experimental teaching equipment advanced.It improves the quality and efficiency of experimental teaching and research, is a new direction of development of experimental teaching, and promotes the progress of laboratory technology.The LabVIEW programming language is flexible, open, the software replaces the instrument function, has the good user interface, the operation is simple and so on. The electrician and the electronic class course is an important link which the electrician and the electronic class specialized student studies, the curriculum theory is strong,The virtual laboratory is set up on the computer, and the virtual experimental instrument designed by using the LabVIEW development platform can realize the common experiments in electrical and electronic courses, including branch current method, node voltage method, first-order dynamic circuit analysis, etc.Research on the second order dynamic Circuit Analysis of RLC Series Resonance Circuit Design of 1st order Frequency response 3-8 Line Decoder selected 1 data Selector, synchronous binary counter Simulation, etc.The design of virtual signal generator based on sound card and the design of virtual oscilloscope can improve students' interest in learning, make up for the deficiency of experiment teaching in hardware environment, and improve the teaching quality of electrical and electronic course experiment teaching.The teaching effect is improved.
