摘要
介绍了通过单片机控制的电源插座开关系统。利用单片机控制的电源可使开关电源具备更加完善的功能,便于实时监控。该系统以传统的89C51单片机为核心,通过软件控制继电器来对电路进行定时开断、过电保护,通过ADC0808来显示电压、电流,从而实现动态监控等功能;实现了对电路的定时控制和保护,有利于节能,提高用电效率。整个集群控制系统实现的关键在于对单片机的编程设计,介绍了有关定时功能、动态显示、A/D转换的编程思路和关键程序,通过proteus仿真,实现单片机对电源的集群控制功能。
This paper presents the system of switch of current source by microcomputer. The power controled by microcomputer can own complete function in order to observe all the time. It depends on 89C51 and uses software to control the current on time and protect the current. Through ADC0808,it can display voltage and current to finish the function of control. In this way,it can save energy and improve the efficiency of electricity. All the system＇s key is microcomputer programming. It presents the important part of programming of setting time,displaying and A / D changing. By Proteus simulation,it completes these functions.
