Abstract:This paper attempts to compare the advantages and disadvantages of various modern communication mode and the GSM network short news business, and draw the conclusion that advantages of introduced by using existing GSM network of short news business to realize the remote security control system, and various advantage will be used in the design of the way the system. GSM technology has developed into a fairly mature stage, using this communication module and the Internet by single-chip microcomputer chip, as the key control parts, responsible for judgment by sensor test to deal with the situation, and use the standard AT directive driven Siemens TC35i realize the sending and receiving text messages and voice calls. Users in the received information according to situation after police sent a message to a single-chip microcomputer, microcontroller will to receive short message is analyzed, and the instruction information extraction and carry out, and then realize the control of the controlled object. The paper discusses the GSM system composition structure, the main business, focusing on the short news business characteristics, structure, etc, and based on this set up the whole system. A detailed account of the system hardware component of main and function, gives the whole system software flow chart and the terrorists program flow chart. Introduces the technology of application. And puts forward the system of some problems to be solved.
