基于单片机的数字电压表设计
摘要
在日常维修、教学和科研中,电压表是不可缺少的。本课题目的就是以单片机为基础设计出一种结构简单、工作可靠、灵活性好的数字电压表。
本文首先介绍了数字电压表的发展现状及课题的目的和意义。然后,对基于单片机的数字电压表的硬件系统、软件系统的设计原理及具体实现方案作以详细介绍,其中,在硬件部分,较为详细的讨论了硬件的选择、设计原理、使用方法和功能,同时,对各部分接口电路作以介绍;在软件部分,介绍了软件所使用的编程语言和编程思路。最后,对电路调试、印刷PCB板的制作及系统的抗干扰设计作了进一步分析和总结。
本文设计的数字电压表,其硬件电路所用元件较少、成本低、调节简单;软件采用C语言编程,其灵活性高,可读性强。经过理论研究、原理设计和整机调试,实验结果表明,该方案可行。

Design of Digital Voltage Meter Based on MCU
Abstract
In routine maintenance, teaching and research, voltage meter is indispensable. A direct current digital voltage meter has been designed, which is based on MCU, and has a simple structure, reliable, flexible.
Firstly,this paper introduced the development of the base on MCU digital voltage meter and the purpose and significance of topic. Then in details this paper described the design principle of hardware and software systems. And in details the hardware part present a discussion in hardware selection, design principles, instructions and the function, further more, some of the interface circuit have been introduced. The software part introduced the programming language and programming ideas used in codes. Finally, the circuit debugging, the printed plate of PCB production and the anti-jamming system were designed to further analysis and synthesis.
The digital voltage meter designed here, have ponents in the hardware part, lower cost and easier testing; software used C programming language which is high flexibility and strong readability. After theoretical research, principle design and debugging, the experimental results suppose it is feasible of choosing this program.
