【摘要】：理論和實(shí)驗(yàn)的相互促進(jìn),可以很好的提高學(xué)生的綜合水平。傳統(tǒng)的教學(xué)實(shí)驗(yàn)受制于傳統(tǒng)實(shí)驗(yàn)箱,測(cè)量?jī)x器的數(shù)量和維護(hù)狀態(tài),不能很好的完成實(shí)驗(yàn)教學(xué)的任務(wù),無(wú)法達(dá)成對(duì)學(xué)生能力的培養(yǎng)。以“軟件即儀器”作為核心理念的虛擬儀器技術(shù)的應(yīng)用,可以很好的解決這些問(wèn)題。同時(shí)隨著通信技術(shù)的進(jìn)步,可以進(jìn)行遠(yuǎn)程訪問(wèn)和操作的虛擬實(shí)驗(yàn)室使得使用者能夠隨時(shí)隨地完成實(shí)驗(yàn)項(xiàng)目,可以和傳統(tǒng)的實(shí)驗(yàn)教學(xué)進(jìn)行相互補(bǔ)充,很好的提高了理論知識(shí)的教學(xué)效果。本文以LabVIEW為開(kāi)發(fā)平臺(tái),采用了模塊化編程,實(shí)現(xiàn)了通信信號(hào)與通信電路實(shí)驗(yàn)平臺(tái)。LabVIEW前面板中的控件對(duì)現(xiàn)實(shí)物件的高仿真度,使得設(shè)計(jì)的實(shí)驗(yàn)平臺(tái)擁有良好的交互界面,獲得和實(shí)際實(shí)驗(yàn)相仿的感受。本平臺(tái)的純軟件對(duì)模擬通信和數(shù)字通信中主要的調(diào)制解調(diào)功能進(jìn)行了設(shè)計(jì)仿真,并通過(guò)模塊化設(shè)計(jì),利用狀態(tài)機(jī)分別集成為模擬通信和數(shù)字通信實(shí)驗(yàn)?zāi)K。再通過(guò)邏輯函數(shù)控制前面板界面的操作邏輯,使得各個(gè)實(shí)驗(yàn)?zāi)K部分的操作界面互補(bǔ)干擾,根據(jù)相對(duì)于的模塊,顯示相對(duì)應(yīng)的控件。在軟件和硬件相結(jié)合的部分,通過(guò)將聲卡作為數(shù)據(jù)采集卡,設(shè)計(jì)了實(shí)驗(yàn)室中常用的雙通道示波器和信號(hào)發(fā)生器,同時(shí)內(nèi)置了模擬信號(hào)源,可以在音頻范圍實(shí)現(xiàn)對(duì)應(yīng)的功能。最后通過(guò)動(dòng)態(tài)鏈接的方法,通過(guò)子面板,將這些模塊集合在一起,使用遠(yuǎn)程控制面板的方法,對(duì)這個(gè)系統(tǒng)進(jìn)行了網(wǎng)絡(luò)發(fā)布,實(shí)驗(yàn)人員通過(guò)瀏覽器就可以訪問(wèn)本實(shí)驗(yàn)平臺(tái),完成相應(yīng)的實(shí)驗(yàn)操作。
[Abstract]:The mutual promotion of theory and experiment can improve the comprehensive level of students.The traditional teaching experiment is limited by the traditional experiment box, measuring the number of instruments and maintaining the state, can not complete the task of experimental teaching well, can not achieve the cultivation of students' ability.The application of virtual instrument technology based on "software is instrument" can solve these problems well.At the same time, with the development of communication technology, the virtual laboratory, which can conduct remote access and operation, enables users to complete the experimental projects anytime and anywhere, and can complement each other with the traditional experimental teaching.It improves the teaching effect of theoretical knowledge.This paper takes LabVIEW as the development platform, adopts the modularization programming, realizes the communication signal and the communication circuit experiment platform. LabVIEW in the front panel control to the reality object high imitation degree, causes the design experiment platform to have the good interactive interface.Get a feeling similar to that of the actual experiment.The pure software of this platform designs and simulates the main modulation and demodulation functions in analog communication and digital communication, and integrates the state machine into analog communication and digital communication experiment module by modularization design.Then the logic function is used to control the operation logic of the front panel interface, which makes the operation interface of each experimental module complementary to each other. According to the relative module, the corresponding control is displayed.In the part of the combination of software and hardware, the sound card is used as the data acquisition card to design the dual-channel oscilloscope and signal generator commonly used in the laboratory. At the same time, the analog signal source is built in, which can realize the corresponding function in the audio range.Finally, through the method of dynamic link, through the subpanel, these modules are gathered together, using the method of remote control panel, the system is published on the network, the experimenter can access the experimental platform through the browser.Complete the corresponding experimental operation.
