Study On Wireless Communication System Based On The SMS Of GSM

The development of the mobile communication in our country is stepping in a period of fast enlargement. The business and application of short message are developing very quickly and widely as the simple and convenient means of data communication. We realize the long-distance communication by short message service of GSM network. It applies to the waterworks and is appropriate to the features of wide covering, the dispersing of the monitoring collection points and non-scheduled and unfixed monitoring of the water pump of the well in the waterworks.This paper includes six parts. It makes up of the prolegomenon, the concepts and structure of short message service of GSM, the peripheral circuit design of TC35i module and the realization of short message service, the function realization of the control system, the structure design and function realization of the terminal system and the design of wireless communication system.The first part of the paper narrates the purpose, the significance of the item and the application of the system. The second part of the paper introduces simply the structure of GSM network and the characteristics of short message service of GSM, analyses completely the transmission theory of short message service based on GSM network and the realization methods of its protocols. The third part of the paper discusses emphatically the characteristics of the TC35i module, designs the peripheral circuit of it, and emphasizes the code scheme of protocol description unit and the application of AT command on controlling the receiving and sending of short message. The fourth part of the paper designs and realizes the function of the control system. The fifth part of the paper designs the structure and function of the terminal system, describes the design of the flow frame, the program and the design of the circuit according to the function of the terminal system. The sixth part of the paper introduces the function design of the wireless communication system according to short message service, decides the structure of the system.The paper researches how to realize the technique of data collection of single chip computer in the distance, communication, data receiving in the control system, controlling and the interface communication of the computer by the combine of SMS and data transmission between the GSM module and PC,the single chip system and introduces its practical foreground and value.
