摘　　要：普通的数字电压表只能将电压信号测量并显示出来,在很多既要精确测量又要实现控制功能的电子产品设计中很难满足要求。利用单片机设计一种可控积分式直流数字电压表,该电压表通过软件可以实现高精度A/D转换,并可根据需要实现对被测信号的控制,具有抗干扰强,精度高等特性。Although the general digital voltage meter can be used to measure and display the voltage signal, it cannot meet the demand of accurate measurement and control function in the design of electronic products. A controllable Dual Integral direct current digital voltage instrument was designed by use of SCM （Single Chip Micocomputer） in this paper. The instrument provides with the control function to the measure signal, and at the same time the high accurate voltage value can be obtained. The instrument can also implement the measuring subsection demarcation, and has the peculiarity of resisting interference and high accurate measurement.
