Research Of Radio Frequency Identification Technology In Wireless Security System

RFID is now becoming a new technology widely used in intelligent building's door forbidding, administration of parking lot and patrolling, and guarding against thief systems. This AUTO ID technology has been rose form 1990' s. It is also called electronic label.This paper introduced RFID technology used in wireless security systems. The emphases 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. Firstly, the paper presents the theory of RFID, and then introduces the whole system's structure, working theory, communication protocol, and the system's network. Each hardware has been presented. This system is a modularization system, which is consisted of several function modules. The hardware-chapter introduces every hardware modules' design idea and electro-circuit principles. In this chapter the introduction of the important components are include, too.As a modularization system's firmware, the programs are modularization, too. In software-chapter, the communication protocols and the functions of each program modules are introduced detailedly.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 a reliable application that is based on the wireless data transmitting modules. And this application has been tested by practice, having reached the requirements.
