摘要
以FPGA为数字逻辑平台,借助继电器矩阵和多路模拟开关,以ADS1211为核心,在单片机控制下,联合实现手持式虚拟/智能存储示波表中数字多用表功能,实验表明该设计是行之有效的。文中介绍了数字多用表的系统结构,重点讨论了其测量电路和智能控制方案。
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 plotˉform,ADS1211forkernel chip,the experimentshowed the designwas feasible,the systemstruction was presentˉed in the paper,measure circuit and intellect control plan of digital multimeter were mainly given.
