摘  要

 本文主要敘述了研究本設(shè)計(jì)的目的、意義以及本系統(tǒng)可能使用的場(chǎng)合。介紹了GSM網(wǎng)絡(luò)體系結(jié)構(gòu)及GSM短消息的特點(diǎn)。討論了系統(tǒng)使用的GSM模塊的特點(diǎn)與性能，對(duì)其外圍電路進(jìn)行設(shè)計(jì)。分析了PDU短消息以及控制短消息收發(fā)的AT命令的應(yīng)用。對(duì)主控端系統(tǒng)的功能進(jìn)行了設(shè)計(jì)和實(shí)現(xiàn)，完成了整個(gè)系統(tǒng)的結(jié)構(gòu)設(shè)計(jì)和功能實(shí)現(xiàn)，進(jìn)行了程序編寫與電路設(shè)計(jì)。最后介紹了該系統(tǒng)的應(yīng)用前景與推廣價(jià)值。
 本設(shè)計(jì)是基于GSM模塊與單片機(jī)系統(tǒng)以及報(bào)警電路的無線通信系統(tǒng)，由GSM模塊、單片機(jī)、報(bào)警電路、天線、電源模塊構(gòu)成。該系統(tǒng)研究了如何把GSM模塊與單片機(jī)系統(tǒng)及報(bào)警電路整合起來，將短消息與報(bào)警結(jié)合起來從而實(shí)現(xiàn)了無線通信與報(bào)警。其工作流程為，開關(guān)打開以后系統(tǒng)會(huì)發(fā)送一條短信到目標(biāo)手機(jī)，然后發(fā)光二極管點(diǎn)亮，繼電器動(dòng)作。這樣就實(shí)現(xiàn)了報(bào)警與無線通信。該系統(tǒng)稍作改動(dòng)即可廣泛應(yīng)用于防盜與工業(yè)控制等方面。

Abstract
 This paper describes the purpose and Significance of studying the design and The possible use of the occasion of this system. Introduce GSM Network Architecture and the characteristics of GSM short message. Discussed the characteristics and performance of the GSM module what the system used,design the Peripheral circuits of system. Analysis the PDU short message code and how use the client application of the AT command to control send short messages.Design and implement the function of Control client, Completed the structural design and function to achieve of the whole system. Carried out the programming and circuit design.Finally, Introduce the the value of promote and Application prospects.
 This design is based on the wireless communicate system of GSM module single-chip system and annunciator circuit,GSM module single-chip annunciator circuit antenna power module make up of the wireless communicate system.This sytem study how to link GSM module single-chip system and annunciator circuit,use short message and alarm to achivev wireless communicate and alarm.The step of the system is that,if the switch close,system will send a short message to the objective mobilephone,then the LED light, the relay closed,in this way the system complete alarm and wirelsee communicate.if the system make some changes,the system will applcate comprehensively in insurance aqainst theft and Industrial Control Etc.
