The Research And Design Of Communication Based On Beidou And GSM

Along with the advance of society, the communication system in plays an important role in people’s life and work. Communication equipment is varied, but in some special occasions, the existing conventional communication system can not complete the message this feature. From actual conditions, this paper according to the development of the communication system, present situation and defects in the fact that, in combination with the project design on special occasions, the message set beidou short message communications, GSM for the integration of embedded communication equipment, and has a bad environment security, stability, real-time transmission message, etc. Beidou short message communication using the beidou satellite of independent research and development in our country as the means of transmitting information, to overcome the bad environment under the defects of conventional communication system to transmit information to the message is not affected by the environment. GSM communication using mobile or unicorn SIM card in the form of text messages, to make the message more convenient real-time., in the design of beidou GSM short message and time-sharing multiplexing, with maximum limit satisfy the stability of the transmission. This paper briefly introduces the working principle of communication system based on beidou and GSM and design method, elaborated the beidou short message communication modules and GSM communication module driven method and the application process, and gives part of the program code, hardware part mainly introduces the beidou short message communication module and the performance of the GSM communication module and peripheral circuit design, basic through hardware and software in detail must be designed safety real-time system can solve the bad environment of the short message.
