Remote Door Access System Based On Wireless Radio Frequecy Identification

We often require closed management for work, life safety and efficiency. With the development of technology, door access systems based on contactless IC card gradually substitute for the original key to door and door access management based on the ID card,which is more secure and efficient.The RFID technology is an automatic identification technology which was matured from 1980s.It is a new type of automatic identification technology,with features of high reliability, strong confidentiality and convenience. Compared with the same period or early contact IC card,the contactless IC card successfully integrates RFID with IC to communicate contactlesslly and bidirectionally.It can control the important physical and logical access efficiently, conveniently and safely when the RFID technology is used in the door access system.The rapid development of computer network technology,represented by Internet,which makes the large-scale communication easier,breaks through the spatio-temporal restrict and area obstacle of the means of traditional communication.The resources of hardware and software owned by the Internet is applied to more and more different areas.it not only can meet people's increasingly complex requirements,but also can make remote and large-scale door access system possible when introduced TCP/IP technology to door access system.In this paper,we use the technology of serial communication and contactless IC card based on RFID to realize cardholders' information management and issuing card operations,we also use Network communication components based on the technology of TCP/IP to monitor people in and out remotely thus achieve safe and effective management.
