Description: 数字电压表是诸多数字化仪表的核心与基础，电压表的数字化是将连续的模拟量如直流电压转换成不连续的离散的数字形式并加以显示，这有别于传统的以指针加刻度盘进行读数的方法，避免了读数的误差和视觉疲劳。目前数字万用表的内部核心部件是A/D转换器，转换器的精度很大程度上影响着数字万用表的准确度.-Digital voltmeter is the core of many digital instrument with the digital voltmeter based, is a analog quantities such as dc voltage converted into digital form of discrete discontinuous and it shows that this is different from traditional pointer to add scale plate, the method of reading to avoid the reading of error and visual fatigue. At present the core digital multimeter parts is A/D converter, the precision of the converter A large extent influence the accuracy of the digital multimeter.

Description: 8路输入模拟信号数值显示巡检数字电压表可以测量0--5V的8路输入 模拟信号电压值，并在4位LED数码管上轮流显示或单路选择显示。
按系统功能实现要求，决定控制系统采用AT89C52单片机，A/D转换采用ADC0809。系统除能确保实现要求的功能外，还可以方便地进行8路其他A/D转换量的测量、远程测量结果传送等扩展功能。
采集 8 个通道的模拟量在数码管显示出来。模拟量值的测量范围是0-255,第2个数码管用于显示哪一个通道，后2个数码管用于显示采集的模拟量的值，每秒钟显示切换一下通道。
本设计还有通道选择的功能．有两个按键,一个是调节轮流显示和选择通道两种功能的转换，另一个是选择通道的切换。要注意的地方：
1、只有当轮流显示的通道快显示到通道8后，长按住功能转换键等出现数码管全熄灭后再放开，就会转到选择通道的功能。
2、切换通道时，也要长按一会，等出现数码管全熄灭后再放开。-8 road input analog signals that digital voltmeter measurement circuit can 0-5 V 8 road input analog signals voltage value, and in the four LED digital display or taking turns on the single option to show.
