本系统是基于AT89C52单片机设计的，由具有8通道的模数转换芯片ADC0809采集模拟信号，并将采集到的数据送入AT89C52进行处理，其中ADC0809的1MHZ时钟脉冲直接由单片机的ALE脚输出的六分频时钟信号经过74LS74二分频得到。在设计中采用了精简电路及充分利用软件资源为原则，采用了软件译码，并利用三极管扩流来驱动数码管。同时兼顾系统的性能指标，采用了四位数码管进行动态显示，分别显示模拟通道数以及采集到的模拟电压的数值。本系统经设计调试达到了预期的设计要求，能够标准地自动轮流显示8路模拟电压数值量，精度为0.02V，误差系数为0.01。

The system is based on the design of the AT89C52 SCM, with the 8-channel analog-digital conversion chip ADC0809 acquisition analog signals, and the data collection process into the AT89C52, which ADC0809 of 1 MHZ clock directly from the SCM ALE The six-foot-frequency output clock signal after 74 LS74 frequency by two points. In the design of circuits used in the streamlining of resources and make full use of software to the principle of using the software decoding and expanding the use transistor to drive the flow of digital. At the same time take into account the performance indicators, used four of dynamic digital, analog channels respectively, and collected the analog voltage values. Commissioning of the system is designed to achieve the desired design requirements, standards and can automatically rotate 8 numerical simulation of voltage, the accuracy of 0.02 V, error factor of 0.01.
