基于AT89S52的远程电源监控系统设计

本文介绍的是设计一种基于单片机AT89S52的远程电源监控系统，通过监控那些系统工作电源的参数来判断系统是否正常工作，以满足这些系统所需要的高可靠性、高实时性和维护方便性的特点。简单介绍了GSM网络和GSM短消息业务，重点分析了短信技术包括短消息的基本概念、短信的规范与协议、AT指令集，PDU格式、以及各种短信编码格式。然后文章具体设计了集GSM网络、单片机、数据库于一体的远程电源监控系统。本系统主要由远程监控终端和中心服务器两部分组成，远程监控终端和中心服务器之间的通信链路是GSM网络，数据传输是通过短消息的具体形式实现。

Design of Remote Monitor System of Power Supply Based on AT89S52

This passage introduces a kind of remote monitor system of power supply based on AT89S52 which estimate whether the system is working by monitoring those parameter of system Power in order to obtain high stability,high real time property and convenience which the system Needs.It also introduces GSM net and GSM short message operation,mainly analyzes the short message Technology including the basic notion ,criterion,agreement,AT cornmand,PDU format and every kind Of coding format.Then it presents the remote monitor system of power supply including GSM net ,chip and data base.This system is made up of by remote monitor terminal and central server, The remote monitor terminal communicate with central server by GSM net and its data transmit by Short message.
