| 摘 要： | 由于纯硬件数字电压表结构复杂,测量精度低,价格高,而在日常使用中,使用频率高,导致万用表经常损坏,故障率高,给使用和维修带来很多不便.为了设计一种高精度数字电压表,采用AT89C52单片机和ADC0809模/数转换相结合的方法,做了大量Proteus仿真实验,获得了普通纯硬件数字电压表无法达到的测量效果.实验结果证明,使用软硬件相结合设计的数字电压表,具有结构简单,测量精度高,故障率低等功能.

| Abstract: | The complex structure,low precision and high price of hardware-only digital voltmeter and high frequency of use in daily usage result in frequent damage and high failure rate,which bring a lot of inconvenience.The combination method of AT89C52 single chip microcomputer and ADC0809 analog-to-digital conversion is adopted in the design of a digital voltmeter with high precision.A lot of Proteus simulation experiments are made,and the measurement results which the ordinary pure hardware digital voltmeter can not achieve are obtained.The experimental results show that the digital voltmeter using the combination method of software and hardware has the advantages of simple structure,high accuracy and low failure rate. |
