基于AT89S52的遠程電源監控系統設計

摘要：本文介紹的是設計一種基于單片機AT89S52的遠程電源監控系統，通過監控那些系統工作電源的參數來判斷系統是否正常工作，以滿足這些系統所需要的高可靠性、高實時性和維護方便性的特點。簡單介紹了GSM網絡和GSM短消息業務，重點分析了短信技術包括短消息的基本概念、短信的規范與協議、AT指令集、PDU格式、以及各種短信編碼格式。然后文章具體設計了集GSM網絡、單片機、數據庫于一體的遠程電源監控系統。本系統主要由遠程監控終端和中心服務器兩部分組成，遠程監控終端和中心服務器之間的通信鏈路是GSM網絡，數據傳輸是通過短消息的具體形式實現。 敘詞：GSM，短消息，數據庫 Abstract：This passage introduces a kind of remote monitor system of power supply based onAT89S52 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 systemNeeds.It also introduces GSM net and GSM short message operation,mainly analyzes the short messageTechnology including the basic notion ,criterion,agreement,AT command,PDU format and every kindOf 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.
