【摘要】：隨著社會(huì)的不斷進(jìn)步,通信系統(tǒng)在人們的生活工作中起著重要的作用。通信設(shè)備多種多樣,但是在某些特殊場(chǎng)合,現(xiàn)有的常規(guī)的通信系統(tǒng)不一定能完成傳遞消息這一功能。本文從實(shí)際出發(fā),根據(jù)通信系統(tǒng)的發(fā)展現(xiàn)狀及存在缺陷這一事實(shí),結(jié)合項(xiàng)目設(shè)計(jì)了特殊場(chǎng)合下傳遞消息的集北斗短報(bào)文通信,GSM通信為一體的嵌入式通信設(shè)備,具有惡劣環(huán)境下安全、穩(wěn)定、實(shí)時(shí)傳輸消息等特點(diǎn)。北斗短報(bào)文通信利用我國(guó)自主研發(fā)的北斗衛(wèi)星為傳輸信息的手段,克服了惡劣環(huán)境下常規(guī)通信系統(tǒng)無(wú)法傳輸信息的缺陷,使傳遞消息不受環(huán)境影響。GSM通信利用移動(dòng)或聯(lián)通SIM卡以短信的形式傳遞消息,使傳遞消息更加方便實(shí)時(shí)。設(shè)計(jì)中,北斗短報(bào)文和GSM通信分時(shí)復(fù)用,以最大限度的滿(mǎn)足傳輸?shù)姆�(wěn)定。文中簡(jiǎn)要的介紹了基于北斗和GSM的通信系統(tǒng)的工作原理和設(shè)計(jì)方法,詳細(xì)闡述了北斗短報(bào)文通信模塊和GSM通信模塊的驅(qū)動(dòng)方法和應(yīng)用程序流程,并給出了部分程序代碼,硬件部分重點(diǎn)介紹了北斗短報(bào)文通信模塊和GSM通信模塊的性能和外圍基本電路設(shè)計(jì),通過(guò)軟硬件的詳細(xì)介紹務(wù)必設(shè)計(jì)出可以解決惡劣環(huán)境下系統(tǒng)穩(wěn)定安全實(shí)時(shí)的傳遞短消息。
[Abstract]:With the development of society, communication system plays an important role in people's life and work. There are a variety of communication devices, but in some special cases, the existing conventional communication systems may not be able to complete the function of messaging. According to the actuality of the communication system and the fact that the communication system has defects, this paper designs the embedded communication equipment which integrates Beidou short message communication and GSM communication. It has the characteristics of security, stability and real-time transmission of messages in bad environment. Beidou short message communication uses Beidou satellite, which is independently developed by our country, as a means of transmitting information, which overcomes the defect that conventional communication system can't transmit information under bad environment. GSM communication uses mobile or Unicom SIM card to transmit message in the form of short message, which makes the transmission of message more convenient and real-time. In the design, Beidou short message and GSM communication time-sharing multiplexing, in order to maximize the stability of the transmission. This paper briefly introduces the working principle and design method of the communication system based on Beidou and GSM, expounds in detail the driving method and the application program flow of the Beidou short message communication module and the GSM communication module, and gives some program codes. In the hardware part, the performance of Beidou short message communication module and GSM communication module and the design of peripheral basic circuit are introduced. Through the detailed introduction of hardware and software, we must design the short message transmission which can solve the problem of system stability, security and real time under the bad environment.
