摘要
针对电网电压数据的实时监测,提出了一种基于STC12C5A60S2微处理器的方案。该系统包括电压采集模块、转换模块和数据显示模块,可以显示实时时间和电压,并具有电压越限报警、系统变比设定、系统电压系数调节、电压统计等功能。该系统采用了最新的1T高性能51单片机和存储器,加快了系统的处理和存储速度。软件采用高级语言编写,主要包括初始化、按键扫描、菜单处理、电压统计等模块化子程序。
A design based on micro - controller STC12C5A60S2 is introduced because of the demand of monitoring the real - time voltage on power grid. This system consists of the voltage data acquisition module and the display module, which can display the real time and real -time voltage. It contains the functions as below：warning when the voltage beyond or above the limit and the setting of ratio and system coefficient,and the statistic of the voltage etc. The latest and high effective 1T8051 single chip microcomputer and memory are used to fasten the speed of execution and storage. The program is edited by the high - level language, which Contains the subroutines such as initialization of the system and the key scanning, handling of menu and statistic of the voltage.
