摘要
电压测量在电子测量技术中具有重要意义。以AT89C51单片机为核心,基于proteus仿真平台,设计出两路输入、交替显示的数字电压表(DVM)。文章详细介绍了DVM的系统构成以及工作原理,介绍了核心部件A/D转换器ADC0809外加时钟的proteus仿真方法,给出了DVM的仿真设计电路图,验证了设计正确可行。
It has great significance of voltage measurement in the electronic measurement technology. Taking AT89C51 microcontroller as the core,based on Proteus simulation platform,A digital voltmeter( DVM) is designed for two input and alternating display. This paper introduces the system structure and working principle of digital voltage meter,Proteus simulation method of ADC0809 plus clock is introduced. The circuit diagram of DVM simulation is given. and verifies its correctness by simulation.
