摘　　要：SoC(片上系统)技术的出现,极大改变了数字系统固有的设计思路。基于单片机设计的应用系统功能更强,产品也更小巧。根据数据采集的工作原理,运用AT89S52和AD678进行模/数转换,设计实现智能数字电压表。最后完成单片机与PC机的数据通讯,传送并显示所测量的电压值。The orginal methods of digital system design have changed greatly because the SoC technology appears.The application system based on sigle-chip microcomputer is powerful in function and small in size.According to Acquist principles,a new kind of digital voltmeter is designed through the analogue-to- digital converter AD678.Lastly,the measured value will be displayed on PC through the RS232 serial communication between sigle-chip microcomputer and PC.
