RFID technology can be classified into low-frequency 125-134 kHz, high-frequency 13.56 MHz, ultra-high frequency 915 MHz and microwave (2.45 GHz) RFID according to its working frequency band. This technology uses the principle of magnetic field mutual inductance to read object information. It has the characteristics of clear boundary, obvious characteristics and strong magnetic field distribution regularity. It is safe for human body. It has password protection and high security at the same time of radio frequency identification. Therefore, it is widely used in all walks of life, especially in archives.
The intelligent management in modern archives combines RFID technology and information processing technology, detects the precise location of archives through the central information management system, and controls various intelligent equipment in the archives, so as to achieve the automation and systematization of archives management and ensure the safety of archives management.
When the archive bag or archive box is put into storage, an RFID tag will be pasted and bound with the information in the system through the tag. When the reader / writer scans the archive, the tag information will be read, and the system will automatically search all the relevant contents of the archive.
The use of intelligent dense racks for file management is an automatic mode. When the files are put on the shelves, the RFID antenna board in the intelligent dense racks will automatically open the scanning mode and bind the file position with the file information and feed it back to the system. The information system of the files can set automatic refresh to update the file position and related information in the rack in real time, Even if the files are put on the shelves in disorder, they can be managed in an orderly manner.
When borrowing files, the user's borrowing card information is bound through RFID technology(more info). The user swipes the borrowing card at the librarian workstation for borrowing. The management personnel will query the file location according to the user's needs. The system will automatically light the specific location of the file in the dense rack. The management personnel will take the file from the corresponding location. The user can take the file after completing the borrowing procedures.
When archives are filed, the return procedures performed by the user at the librarian workstation, such as reading and writing of labels and brushing of borrowing and reading cards, complete the return of the archives. The management personnel scan the label information through the system, check the return location of the archives, and place the archives in the correct location according to the system and the dense shelf indicator light.
During the file counting, the central processing system starts the counting procedure, and the RFID antenna board of the dense rack automatically scans and reads the file position and information in the rack. In case of abnormality or loss, it will automatically prompt and alarm.
The application of RFID has taken a big step in the intellectualization and automation of file management. It can automatically and accurately determine the location and status of files. In the whole process, it can realize unmanned management, greatly improve work efficiency, avoid some problems in human operation, and improve the security of encrypted files.
