【摘要】：高校傳統(tǒng)實驗教學(xué)以組為單位作實驗,使部分同學(xué)難以全部參與和投入,沒能充分了解和掌握實驗全過程,儀器設(shè)備成本高,而且由于場地及課時的限制造成實驗室設(shè)備也不能充分利用,最終浪費了學(xué)校大量的人力物力,同時學(xué)生還不能真正地掌握實驗,學(xué)習(xí)效率較低�；谟嬎銠C技術(shù)的虛擬儀器的引入,不但可以節(jié)約大量儀器設(shè)備的經(jīng)費投入,而且更新和調(diào)整的實驗方法和手段使得實驗室的實驗教學(xué)設(shè)備保持其先進性,提高了實驗教學(xué)和科研的質(zhì)量與效率,是實驗教學(xué)的一個新的發(fā)展方向,促進了實驗室技術(shù)的進步。 LabVIEW編程語言靈活、開放、用軟件代替了儀器功能,具有良好的用戶界面、操作簡單等優(yōu)點,電工與電子類課程是電類相關(guān)專業(yè)學(xué)生學(xué)習(xí)的一個重要環(huán)節(jié),課程理論性較強,在計算機上建立虛擬實驗室,應(yīng)用LabVIEW開發(fā)平臺設(shè)計的虛擬實驗儀器可以實現(xiàn)電工電子類課程中常見的實驗,包括支路電流法、節(jié)點電壓法、一階動態(tài)電路分析、二階動態(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、同步二進制計數(shù)器仿真等模塊的設(shè)計,以及基于聲卡的虛擬信號發(fā)生器設(shè)計和虛擬示波器的設(shè)計,以此可提高學(xué)生學(xué)習(xí)興趣,彌補了硬件環(huán)境下實驗教學(xué)的不足,改進了電工與電子課程實驗教學(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.
