智能用电监测系统的研制

Development of an Intelligent Moitoring System for Electric Power Utilization

本文介绍了一种结构简单的单片机用电监测系统。该系统能监测用户的用电情况，并打印记录用户的用电起止时间。系统采用ＭＣ６８ＨＣ０５系列单片机，结构简单、体积小、功耗低、配有ＭＣ６８ＨＣ６８Ｔ１实时时钟，掉电可保持时间及系统信息。

In the paper an intelligent monitoring system with simple structure based on a microcontroller for electric power ulitization is introduced.The system can detect the details of electricity-consuming of electrical equipment,and record the power-on and power -off time. It is featured by small size, low consumption,available MC68HC68T1 realtime clock, automatical keeping time and system message protecting at sudden power break down.
