【摘要】:通信設(shè)備設(shè)計(jì)中對(duì)性能的測(cè)試是一個(gè)非常重要的工作,在某型號(hào)通信設(shè)備研制完成后的測(cè)試中,需要快速的對(duì)其性能進(jìn)行測(cè)試以驗(yàn)證通信設(shè)備的通信可靠性以及驗(yàn)證其設(shè)計(jì)是否達(dá)到相應(yīng)功能指標(biāo)。近年來,以數(shù)字通信技術(shù)為主體的新型通信設(shè)備開始定型生產(chǎn)。新設(shè)備功能強(qiáng)、集成度高、指標(biāo)多,投入量產(chǎn)后,勢(shì)必對(duì)生產(chǎn)單位的產(chǎn)品生產(chǎn)周期提出很高的要求。傳統(tǒng)的人工測(cè)試方法速度慢、誤差大、記錄準(zhǔn)確性低。為了快速的滿足這些性能參數(shù)的測(cè)試需求,就需要基于自動(dòng)化測(cè)試方案建立恰當(dāng)?shù)臏y(cè)試環(huán)境,開發(fā)集成一體化的測(cè)試平臺(tái)。論文首先從實(shí)際測(cè)試的相關(guān)背景入手,歸納總結(jié)出整體的測(cè)試需求和方案,其次對(duì)測(cè)試方案進(jìn)行了分析和匯總,確定了課題研究中的關(guān)鍵技術(shù),最后以相關(guān)的自動(dòng)化測(cè)試技術(shù)為理論依據(jù),完成某通信設(shè)備性能測(cè)試儀的總體方案設(shè)計(jì)。文中確定了對(duì)該通信設(shè)備性能測(cè)試儀所要著力進(jìn)行的測(cè)試項(xiàng)目,包括同步概率測(cè)試、話音功能測(cè)試、數(shù)據(jù)功能測(cè)試以及接口電平和輸入輸出阻抗的測(cè)試;跍y(cè)試系統(tǒng)的總體方案和要求,提出了模塊化的系統(tǒng)設(shè)計(jì)理念,從硬件上對(duì)各個(gè)功能區(qū)進(jìn)行了模塊電路的劃分,以單片機(jī)硬件平臺(tái)為基礎(chǔ),分別完成對(duì)各個(gè)子功能模塊的方案設(shè)計(jì)。最后根據(jù)實(shí)際測(cè)試環(huán)境進(jìn)行了測(cè)試驗(yàn)證,該通信設(shè)備性能測(cè)試儀的各項(xiàng)指標(biāo)滿足設(shè)計(jì)要求,達(dá)到了預(yù)期目的。本論文立足于工程實(shí)踐,開發(fā)相應(yīng)的通信設(shè)備性能測(cè)試設(shè)備。該設(shè)備以現(xiàn)有測(cè)試中心為背景,基于工控機(jī)測(cè)試平臺(tái),包括基帶、音頻和數(shù)據(jù)接口三種接口單元。整體硬件平臺(tái)以單片機(jī)為核心,外加功能模塊電路所組成,包括基帶調(diào)制解調(diào)電路、信號(hào)源電路、單片機(jī)測(cè)試電路、阻抗和電平測(cè)試電路、自檢電路接口電路等。在已知同步體制的條件下,利用測(cè)試控制軟件可以對(duì)被測(cè)設(shè)備的同步概率、話音和數(shù)據(jù)通信功能、電臺(tái)接口輸入輸出阻抗、輸入輸出電平等性能指標(biāo)進(jìn)行功能和指標(biāo)性的測(cè)試,在測(cè)試完成后能夠自動(dòng)將測(cè)試數(shù)據(jù)傳回測(cè)試中心顯示、保存和打印,大大提高了工作效率。本課題實(shí)現(xiàn)了理論研究與實(shí)際應(yīng)用的同時(shí)進(jìn)行,該通信設(shè)備性能測(cè)試儀具有較好的發(fā)展前景和實(shí)用價(jià)值。
[Abstract]:It is very important to test the performance in the design of communication equipment. It is necessary to test its performance quickly to verify the communication reliability of the communication equipment and to verify that its design meets the corresponding functional targets. A new type of communication equipment with digital communication technology as the main body began to be finalized and produced. The new equipment has strong function, high integration, many indexes, and postpartum input. The traditional manual testing method is slow in speed, large in error and low in recording accuracy. In order to meet the test requirements of these performance parameters quickly, the traditional manual testing method is bound to put forward a very high demand for the production cycle of the production unit. It is necessary to establish an appropriate test environment based on the automated test scheme and to develop an integrated test platform. Firstly, this paper summarizes the overall test requirements and schemes from the relevant background of the actual test. Secondly, the test scheme is analyzed and summarized, the key technologies in the research are determined, and the related automatic test technology is used as the theoretical basis. The overall scheme design of a communication equipment performance tester is completed. In this paper, the test items for the communication equipment performance tester are determined, including synchronization probability test, voice function test, Data function testing and interface level and input / output impedance testing. Based on the overall scheme and requirements of the test system, a modular system design concept is proposed. Based on the single chip microcomputer hardware platform, the scheme design of each sub-function module is completed respectively. Finally, according to the actual test environment, the test verification is carried out, and each index of the communication equipment performance test instrument meets the design requirements. This paper bases on the engineering practice, develops the corresponding communication equipment performance test equipment. The equipment takes the existing test center as the background, based on the industrial control computer test platform, including baseband, Audio and data interface three interface units. The whole hardware platform is composed of single-chip microcomputer as the core, plus functional module circuit, including baseband modulation and demodulation circuit, signal source circuit, single-chip microcomputer test circuit, impedance and level test circuit, Under the condition of known synchronization system, the test control software can be used to measure the synchronization probability, voice and data communication function, input and output impedance of radio interface, The performance index such as input and output level can be tested by function and index. After the test, the test data can be automatically sent back to the test center to display, save and print the test data. The work efficiency is greatly improved. This subject realizes both theoretical research and practical application. The performance tester of communication equipment has a good development prospect and practical value.
