【摘要】：随着社会的不断进步,通信系统在人们的生活工作中起着重要的作用。通信设备多种多样,但是在某些特殊场合,现有的常规的通信系统不一定能完成传递消息这一功能。本文从实际出发,根据通信系统的发展现状及存在缺陷这一事实,结合项目设计了特殊场合下传递消息的集北斗短报文通信,GSM通信为一体的嵌入式通信设备,具有恶劣环境下安全、稳定、实时传输消息等特点。北斗短报文通信利用我国自主研发的北斗卫星为传输信息的手段,克服了恶劣环境下常规通信系统无法传输信息的缺陷,使传递消息不受环境影响。GSM通信利用移动或联通SIM卡以短信的形式传递消息,使传递消息更加方便实时。设计中,北斗短报文和GSM通信分时复用,以最大限度的满足传输的稳定。文中简要的介绍了基于北斗和GSM的通信系统的工作原理和设计方法,详细阐述了北斗短报文通信模块和GSM通信模块的驱动方法和应用程序流程,并给出了部分程序代码,硬件部分重点介绍了北斗短报文通信模块和GSM通信模块的性能和外围基本电路设计,通过软硬件的详细介绍务必设计出可以解决恶劣环境下系统稳定安全实时的传递短消息。
[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.
