【摘要】：實(shí)驗(yàn)教學(xué)在高等工科教育中起著相當(dāng)重要的作用,尤其是電工電子等實(shí)踐性很強(qiáng)的專業(yè)。在目前大學(xué)擴(kuò)招的形式下,高校實(shí)驗(yàn)室教學(xué)中需要大量的各種測(cè)試儀器。而實(shí)驗(yàn)儀器基金投資金額巨大,設(shè)備技術(shù)更新快,儀器維護(hù)困難,導(dǎo)致很多高校實(shí)驗(yàn)室測(cè)試儀器緊缺。虛擬儀器技術(shù)是計(jì)算機(jī)技術(shù)與電子儀器相結(jié)合而產(chǎn)生的一種新的儀器模式。這種儀器模式的產(chǎn)生不但為測(cè)量領(lǐng)域帶來(lái)了革命性的創(chuàng)新,同時(shí),基于其優(yōu)越的性價(jià)比,也越來(lái)越被高校實(shí)驗(yàn)室所青睞。將虛擬儀器應(yīng)用于高校實(shí)驗(yàn)室可大幅度降低實(shí)驗(yàn)室改造、建設(shè)和維護(hù)的資金、時(shí)間和空間成本,提高使用效率；能為學(xué)生提供更多、更新、更好的高檔低價(jià)儀器；通過(guò)軟件的改進(jìn)和完善,可以不斷地?cái)U(kuò)充實(shí)驗(yàn)內(nèi)容,改變并提高實(shí)驗(yàn)手段,提高實(shí)驗(yàn)教學(xué)質(zhì)量。 本文介紹了虛擬儀器技術(shù)在高校電工電子實(shí)驗(yàn)室建設(shè)和實(shí)驗(yàn)教學(xué)中的應(yīng)用意義,分析了基于LabVIEW的虛擬示波器、虛擬信號(hào)發(fā)生器、虛擬數(shù)字電路實(shí)驗(yàn)教學(xué)平臺(tái)的軟件設(shè)計(jì)過(guò)程以及調(diào)試結(jié)果。虛擬示波器、虛擬函數(shù)信號(hào)發(fā)生器系統(tǒng)的設(shè)計(jì),主要闡述了示波器和函數(shù)信號(hào)發(fā)生器的硬件組成,分析了虛擬示波器、虛擬函數(shù)信號(hào)發(fā)生器的模塊組成和各模塊的軟件程序設(shè)計(jì),并對(duì)各模塊的程序進(jìn)行調(diào)試,分析其運(yùn)行結(jié)果；虛擬數(shù)字電路實(shí)驗(yàn)教學(xué)平臺(tái)系統(tǒng)主要包括人機(jī)對(duì)話界面的設(shè)計(jì)和四個(gè)實(shí)驗(yàn)項(xiàng)目的軟件設(shè)計(jì),主要內(nèi)容包括3線-8線優(yōu)先編碼器、全加器、JK觸發(fā)器、BCD—七段顯示譯碼器的硬件電路設(shè)計(jì)分析以及四個(gè)實(shí)驗(yàn)電路的軟件程序設(shè)計(jì)過(guò)程,同時(shí)給出了四個(gè)實(shí)驗(yàn)電路的測(cè)試結(jié)果。 虛擬儀器應(yīng)用于高校實(shí)驗(yàn)教學(xué),目前處于探索開發(fā)階段,但其顯著的經(jīng)濟(jì)性和實(shí)用性己顯示其巨大的優(yōu)勢(shì)和潛力。隨著虛擬儀器的產(chǎn)生和發(fā)展,將帶來(lái)新型實(shí)驗(yàn)方式的產(chǎn)生,推動(dòng)教育方式的重大轉(zhuǎn)變。
[Abstract]:Experimental teaching plays a very important role in higher engineering education, especially in practical majors such as electrician and electronics. A large number of testing instruments are required in laboratory teaching in colleges and universities. However, the fund of experimental instruments has a huge investment amount, the equipment technology is updated quickly, and the maintenance of the instruments is difficult. Virtual instrument technology is a new instrument mode which is combined with computer technology and electronic instrument. This kind of instrument mode not only brings revolutionary innovation to the field of measurement, but also leads to the shortage of testing instruments in many colleges and universities. At the same time, based on its superior performance-price ratio, it is more and more popular in university laboratories. The application of virtual instruments in university laboratories can greatly reduce the capital, time and space cost of laboratory transformation, construction and maintenance, and improve the efficiency of use. It can provide students with more, newer and better high-grade low-cost instruments. Through the improvement and perfection of software, the content of experiment can be continuously expanded, the means of experiment can be changed and improved, and the quality of experimental teaching can be improved. This paper introduces the application significance of virtual instrument technology in the construction of electrician and electronic laboratory in colleges and universities, and analyzes the virtual oscilloscope and virtual signal generator based on LabVIEW. The software design process and debugging result of virtual digital circuit experiment teaching platform. The design of virtual oscilloscope and virtual function signal generator system, the hardware composition of oscilloscope and function signal generator are expounded. The composition of the virtual oscilloscope, the module of the virtual function signal generator and the software program design of each module are analyzed. The program of each module is debugged and the running result is analyzed. The virtual digital circuit experimental teaching platform system mainly includes the design of man-machine dialogue interface and the software design of four experimental items. The main contents include 3-wire -8-line priority encoder. The hardware circuit design of the full adder JK flip-flop and BCD-7 segment display decoder and the software program design process of the four experimental circuits are analyzed. The test results of the four experimental circuits are also given. The application of virtual instrument in experimental teaching in colleges and universities is at present in the stage of exploration and development, but its remarkable economy and practicability have shown its great advantage and potential. With the emergence and development of virtual instrument, it will bring about the production of new experimental methods. To promote a major change in the way of education.
