摘　　要：为了加强和提高电子技术爱好者和电类学生的基础硬件设计能力,本文设计了一种非编程控制、由全硬件电路构成的LED直流数字电压表。采用分模块的设计方法,在EDA平台Proteus上,按系统调试顺序,分别对A/D转换模块、时钟模块、移位计数模块(二进制—BCD转换模块)、复位/启动模块和LED显示模块进行了仿真设计。通过Proteus中模块化设计仿真与实物焊接、调试,实现了设计任务要求。该数字电压表具有测量误差低、成本低廉和便于携带等特点。In order to strengthen and improve the basic hardware design ability of electronic technology enthusiasts and electrical class,a LED digital voltage meter of directly current is designed in this paper,which is composed of whole hardware circuit without programmable control.The designing and analyzing method of the sub module is used to design and simulate every module according to the system debugging order on the EDA platform of Proteus.These modules are separately A/D conversion module,clock module,shift counter module（binary to BCD conversion module）,start and reset module and LED display module.The system design task requirement is realized by designing and simulation on Proteus and by actual circuit welding and debugging with modules.This kind of voltmeter has the advantages with low measurement error,low cost and easy to carry and so on.
