Based On The Information Transmission Technology Of The Wireless Control Network

With the economy globalization and the high-speed informationization, public security has become the one of those inevitable and important issues in developing and constructing for every country and city. For the success of Beijing Olympic Games 2008 and Shanghai Expo 2010, both Bejing and Shanghai have imported Ituran Location and Control System of Irael, and established Terrestrail Wireless Location & Monitoring Network . This system will provide a safety and reliable wireless information transmission platform for our city, so as to offer a powerful communication system for the non-traditional threats to security. Besides,the system will also be applied in national defence industry flexibly for our country, and bring a further development in informationized construction.By studying the information transmission technology of Ituran system, this paper come up with a scheme for compatibility to Chinese character system, then combine it with micro unit technology and LCD display technology to have designed a LCD display system on the base of this technology to communicate with Ituran system. This display system is being used by Huanwei corporation to monitor and control vehicles. The study and design in this paper give the study of Ituran system the theoretical basis, and it will also provide a reliable technical support for application around the Ituran system.This paper has seven chapters. In the first chapter, I introduce some kinds of methods of wireless information transmission. In chapter two, I introduce the Ituran system's operating principle, and key technology. In the third chapter, I study and analyze the technology of wireless information transmission in Ituran system such as transmittal mode, data structure, property of coding and the feasibility for compatibility to Chinese character system. In chapter four, according to chapter three, I design the function and operational mechanism of an LCD display system in order to set up the communication between it and Ituran system. In the fifth chapter, I will give the implement method of hardware and software in LCD display system development. In chapter six, I will test the whole system and analyze the result. In the seventh chapter, I will write some optimal design of LCD display system. To sum up the above paragraphs, this paper will study wireless information transmission of Ituran system, and apply the theory into practice, so that it can provide valuable experience and technical reserve in further study of the system in the future.
