The Research Of Wireless Security System Based On Radio Frequency Identification

With the rapid development of society and people's living, the need has been changed from only the living space to multiform needs of multi-function, high-quality, safety, intelligence and so on. What's more, the rapid development of electronic and communication technology have provided the security to excogitate the intelligent buildings.RFID is now becoming a new technology widely used in intelligent building's fire alarm systems and guarding against thief systems, patrol management, car park management and door forbidding.This article describes the radio frequency identification technology in the security system. The emphasis of the paper is put on reserving the questions that exist in the security products in markets through researching and discussing the theory of RFID and communication technology. And a home wireless alarm system against gas leakage is developed.Firstly, the paper presents the theory of RFID. Secondly, it introduces composition and working principle of access control system and wireless fire alarm system, the part of hardware discusses the design ideas, function and circuit theory of hardware module; Software design follows the modular design concept to correspond to the various modules of hardware; it includes a brief description of the maining device. Finally, accoding to modular design concept, it discusses the gas leakage prevention design of wireless alarm system.This paper discusses the technology of RFID and communication applied in the door forbidding systems, the wireless fire forbidding and guarding against thief systems. It presents reliable application that is based on the wireless data transmitting modules. And this application has been tested by practice, having reached the requirements. Wireless alarm system against gas leakage can be in normal operation and achieve the desired goals.
