基于AT89C51RC的数字化整流单元的设计

Design of Digital Rectifier Unit Based on AT89C51RC

为了改善整流单元的可操作性,提高系统的可靠性,在模拟整流单元的基础上,设计出数字化的整流单元系统。该系统采用单片机作为主控制器,通过读取同步信号,利用定时器的定时功能在正确的时间发送双窄脉冲波进行整流;用键盘控制参数的设定,用数码管显示参数及状态;读取直流电压、电流值并进行显示;对正反相序均可进行整流,能做到故障报警。

In order to improve the maneuverability and reliability of rectifier unit,this article put forward a digital rectifier which is designed based on analog.This unit used the singlechip computer for the controller of the system.Read the synchronous signal,and the rectifier works with the double narrow pulse which is transmitted in a correct time by the timer.The various control parameter can be enacted by the keyboard,and the fettle of the parameter can be displayed by the digit tube.The system can carryout the rectifier of positive and negative phase sequence current and with the function of alarm for error and so on.
