【摘要】：如今電刷鍍技術(shù)普遍應(yīng)用在生產(chǎn)修復(fù)中,同時(shí)對(duì)電刷鍍電源的可靠性的要求也相應(yīng)地提高。研制一種能夠快速準(zhǔn)確測(cè)試電刷鍍電源的儀器不僅對(duì)電刷鍍電源的發(fā)展起到促進(jìn)作用,同時(shí)還能推動(dòng)電刷鍍技術(shù)的發(fā)展。傳統(tǒng)的測(cè)試方法主要由專業(yè)測(cè)試人員使用獨(dú)立儀器對(duì)電刷鍍電源進(jìn)行測(cè)試,這種測(cè)試方法耗時(shí)長(zhǎng)、效率低,無法滿足工業(yè)化自動(dòng)測(cè)試的要求。如何在現(xiàn)場(chǎng)實(shí)現(xiàn)對(duì)電刷鍍電源的高效測(cè)試是目前電源測(cè)試領(lǐng)域急需解決的問題。因此,本學(xué)位論文設(shè)計(jì)了DSD系列高頻電刷鍍電源測(cè)試儀,該測(cè)試儀能夠?qū)﹄娝㈠冸娫锤邏汉偷蛪褐匾獏?shù)進(jìn)行提取,為現(xiàn)場(chǎng)工作人員提供精度較高的檢測(cè)結(jié)果,便于現(xiàn)場(chǎng)工作人員分析數(shù)據(jù)和維護(hù)電源,有效地提高維修效率。首先,根據(jù)DSD系列高頻電刷鍍電源的工作原理及電源測(cè)試基本方法設(shè)計(jì)了信號(hào)調(diào)理電路(包括高壓參數(shù)、低壓參數(shù)以及IGBT相關(guān)參數(shù)的信號(hào)調(diào)理電路)、人機(jī)接口電路和外圍電路等,針對(duì)電源實(shí)際工作產(chǎn)生數(shù)據(jù)的特點(diǎn),分模塊地采集和顯示數(shù)據(jù)。其次,利用單片機(jī)STC12C5616AD作為整個(gè)測(cè)試儀的核心控制器件,結(jié)合單片機(jī)的PCA硬件捕捉模式對(duì)脈沖頻率進(jìn)行測(cè)量,并且采用拉格朗日插值算法對(duì)紋波數(shù)據(jù)進(jìn)行處理,有效提高了紋波幅度的測(cè)量精度。最后,為了驗(yàn)證測(cè)試儀的準(zhǔn)確性及可靠性,達(dá)到使用測(cè)試儀與傳統(tǒng)的人工測(cè)試相對(duì)比的目的,分別使用本測(cè)試儀和獨(dú)立儀器對(duì)現(xiàn)場(chǎng)電源進(jìn)行測(cè)試,對(duì)比其測(cè)試數(shù)據(jù),對(duì)測(cè)試儀的硬件電路進(jìn)行了調(diào)試和驗(yàn)證。實(shí)驗(yàn)結(jié)果表明,本測(cè)試儀硬件電路穩(wěn)定可靠,能夠快速得到精度較為理想的電源參數(shù)采樣值,符合電源智能化測(cè)試的要求。通過驗(yàn)證,該測(cè)試儀充分考慮了現(xiàn)場(chǎng)測(cè)試的實(shí)際需要,使得電刷鍍電源測(cè)試變得快捷簡(jiǎn)單、準(zhǔn)確有效。
[Abstract]:Nowadays, brush plating technology is widely used in production and repair, and the reliability requirement of brush plating power supply is also raised accordingly. The development of an instrument which can test the power supply of brush plating quickly and accurately can not only promote the development of brush plating power supply, but also promote the development of brush plating technology. The traditional test method is mainly used by the professional tester to test the brush plating power supply. This test method is time-consuming and inefficient, and can not meet the requirements of industrial automatic testing. How to realize the efficient test of brush plating power is an urgent problem in the field of power supply testing. Therefore, this thesis designed DSD series high frequency brush plating power source tester, this tester can extract the important parameters of high voltage and low voltage of brush plating power supply, and provide high precision test results for field workers. Easy for site staff to analyze data and maintain power supply, effectively improve maintenance efficiency. Firstly, according to the working principle of DSD series high frequency brush plating power supply and the basic method of power supply test, the signal conditioning circuit (including high voltage parameters) is designed. The signal conditioning circuit of low-voltage parameters and IGBT parameters, man-machine interface circuit and peripheral circuit, etc., are used to collect and display data in modules according to the characteristics of actual operation of power supply. Secondly, the pulse frequency is measured by using MCU STC12C5616AD as the core controller of the whole tester, and the ripple data is processed by Lagrange interpolation algorithm. The precision of ripple amplitude measurement is improved effectively. Finally, in order to verify the accuracy and reliability of the tester and achieve the purpose of comparing the test instrument with the traditional manual test, the test instrument and the independent instrument are used to test the field power supply, and the test data are compared. The hardware circuit of the tester is debugged and verified. The experimental results show that the hardware circuit of the tester is stable and reliable, and the sampling value of the power supply parameters with relatively high precision can be obtained quickly, which accords with the requirement of intelligent test of power supply. The test results show that the testing instrument takes full account of the actual needs of the field test, and makes the test of brush plating power source quick, simple, accurate and effective.
