以FPGA為數(shù)字邏輯平臺,借助繼電器矩陣和多路模擬開關,以ADS1211為核心,在單片機控制下,聯(lián)合實現(xiàn)手持式虛擬/智能存儲示波表中數(shù)字多用表功能,實驗表明該設計是行之有效的。文中介紹了數(shù)字多用表的系統(tǒng)結構,重點討論了其測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.
