The Realization Of Decentralized Management Model For RFID Readers In Internet Of Things

As the application of Internet of things more and more widely, the development of the Internet of things encountered new problems, which decreases as the Internet of things application system scale, type sensor layer in the Internet of things more and more, quantity is more and more big, the sensor management more and more complex.Read RFID (Radio Frequency Identification) system is a relatively mature Internet application system, this system USES RFID readers, through the Radio Frequency Identification technology, EPC tags are attached to the specific items, speaking, reading and writing, so as to realize or change the item information, and gave the information to the traditional or connected to the Internet, Internet system for convenient management, eventually reach and the connection between the. At this stage in the practical application of RFID read device application system, the management model of RFID readers are the most widely used is the centralized management model, in each place to read management center to manage system, with the expansion of the RFID application system of read, more and more kinds of RFID readers, population continues to increase, due to management continues to increase, the number of read device management center work become more difficult, in order to solve this problem, in most cases to improve the performance of management center, but the performance of the management center to continue to improve to a certain extent brings great economic costs. At the same time, with the expansion of the RFID read device application system, RFID readers, and the average distance of the management center are also increases gradually, the RFID read and the cost of communication between the management center is also growing. RFID read under centralized management model of application system. The above problems, the author of this paper, the design realized the centralized management model of RFID read, in this model is mainly composed of management center, the terminal server and RFID read device of three parts. RFID read and local directly connected to the terminal server and the terminal server under the management of work; Terminal server connection and management center, according to the specific protocol to communicate and work under the control of the management center. At the same time, the terminal server by certain self-management functions, can be independently by the terminal server to control RFID read device; Management center through collaboration and terminal server, most of the control tasks to the terminal server to complete, and RFID readers are no longer connected directly, but through the terminal server indirect control RFID read, complete the work. At the same time, by the terminal server management center will only accept processing good RFID read data, it will reduce the cost of data transmission in the system.Under the centralized management model, only need to increase the number of the terminal server can be very good solve the expansion of application system by RFID readers are brought about by the stress management center and transport stress problem. And since the introduction of the terminal server, RFID readers are not controlled by a management center, but controlled by multiple terminal server, respectively, when management center failure can be controlled by the terminal server temporarily for, this increases the RFID application system of read concurrent processing capability and robustness.
