本系统采用AT89S52为控制核心。该系统由4*4矩阵输入器、cpu部分以及通过8位数码管显示动态扫描0—F 16个数字。输入器由16个按键开关组成；cpu部分由51单片机、晶振片以及电容等组成；显示器由一个8位的7段译码管及电阻构成。

-The system uses AT89S52 as the control core. The system consists of 4* 4 matrix input device, cpu parts as well as through an 8-bit digital tube display dynamic scan 0-F 16 digits. Input is controlled by the composition of 16 key switches　cpu in part by the 51 microcontroller, crystal pieces, as well as capacitors etc.　display by an 8-bit 7-segment decoder tubes and resistors composition.
