Dense archive management system based on high frequency RFID technology and method thereof

Abstract

The invention discloses a dense archive management system based on a high frequency RFID technology. The system comprises a controller, radio frequency reader and writers and a radio frequency tag. The controller makes the radio frequency reader and writers read information of the radio frequency tag. The system is only formed by the controller and the plurality of radio frequency reader and writers. The controller and the radio frequency reader and writers are connected through a data line. The structure is simple and site installation and implementation are convenient to perform. Through adding the controller, the system can be expanded to a radio frequency management system of a multistage controller structure so as to easily cope with large-scale dense archive management. Through ID numbers of the controller and the radio frequency reader and writers, each path of radio frequency antenna is uniquely identified. A lot of detection sensors do not need to arranged on the site, complex software logic does not need to be used to realize accurate positioning, and on-site installation and implementation are convenient and rapid. Hardware structures of the controller and the radio frequency reader and writers are simple, maintenance is convenient, a component quantity and a price are lower than those of components related to a radio frequency module based on a ultrahigh frequency technology, cost performance is high and a good market prospect is possessed.

Description

technical field [0001] The invention belongs to the field of RFID radio frequency identification technology and intensive archives automatic management, and relates to an intensive archives management system and method based on high-frequency RFID technology. Background technique [0002] In recent years, my country's archives industry has achieved considerable development, the scale of the archives industry is expanding day by day, and the requirements for file management are getting higher and higher. RFID radio frequency technology has begun to be widely used. RFID, also known as radio frequency identification, is a wireless communication technology that can identify specific targets and read and write related data through radio signals without contact. RFID technology can be divided into three types: LF (low frequency), HF (high frequency) and UHF (ultra high frequency), which have different characteristics and application environments. The combination of RFID radio fre...
