以FPGA為數(shù)字邏輯平臺(tái),借助繼電器矩陣和多路模擬開關(guān),以ADS1211為核心,在單片機(jī)控制下,聯(lián)合實(shí)現(xiàn)手持式虛擬/智能存儲(chǔ)示波表中數(shù)字多用表功能,實(shí)驗(yàn)表明該設(shè)計(jì)是行之有效的。文中介紹了數(shù)字多用表的系統(tǒng)結(jié)構(gòu),重點(diǎn)討論了其測(cè)量電路和智能控制方案。
Abstract:
The digital multimeter in virtual/intellect digital-oscillorgaph was fulfilled, which was controlled by singlechip computer by relay matrix and analogue switches,in which FPGA was used for digital logical plot-form, ADS1211 for kernel chip, the experiment showed the design was feasible, the system struction was present-ed in the paper, measure circuit and intellect control plan of digital multimeter were mainly given.
