摘 要
GSM(Global System for Mobile communication)移動通信系統是目前移動通訊領域中比較成熟、完善、應用最廣泛的一種系統。作為GSM網絡的基本服務之一的短消息 SMS(Short Message Service),也受到了越來越多的系統運營商和系統開發商的重視,各種基于短信的應用也隨之蓬勃發展起來。本文以GSM移動網絡作為信息傳輸平臺,設計了防盜報警系統。短消息遵循GSM的標準AT指令集,這里著重介紹了和本課題相關的幾條AT指令,同時采用了支持中文的PDU編碼方式。
防盜報警系統的硬件由單片機控制器和移動通信模塊兩部分組成,其中,單片機控制器和移動通信模塊之間通過AT指令進行數據傳輸,移動通信模塊利用GSM網絡實現了與手機用戶的遠程通信。
關鍵詞:單片機;防盜報警系統;短信息
Abstract
GSM(Global System for Mobile communication)is a Popular mobilecommunication system ,which is more mature ,and widely used in mobilecommunication .SMS(Short Message Service),as an important service of GSM, has being widely used in Remote Control .During the Past several years,system operators and system developers have been Paying more and more attention to the usage of SMS .This paper designs Guard against theft and alarm system based on SMS.SMS makes use of standard AT command set of GSM.
The hardware consists of single chip microcontroller and mobile telecommunication module ,data transmission between the single chip microcontroller and mobile telecommunication module is realized by AT instruction ,mobile telecommunication module achieves the distance communication between the system and cell phone users using GSM network. .
Keywords:Single chip microcontroller Guard against theft and alarm system Short message service
