The system implements strict specifications and requirements for the uniform coding, admission registration, borrowing, return, search, inventory, and real-time monitoring of archives, which improves the speed of file review, lending, and return, and improves the accuracy of the shelf. It enhances the information management level of archives management.
RFID technology can be used in several aspects in archive management:
(1) Statistics of physical files: Enter the whole case number, catalog number, title of the file, number of files in the file and storage location in the tag through the RFID read-write device. Labels are installed in the archives, and at the same time, the information is transmitted to the server through the network, and a database is formed after processing by a special management software. After this work is completed, the staff can use the intelligent archive rack automatic collection inventory system when statistical archive collections, and it is no longer necessary to check each case file.
(2) Management of physical archives: through the installation of intelligent security detection doors at the entrance of the archives warehouse, label information is collected in real time. If the physical archives are not authorized to leave the warehouse, the system will immediately alarm in conjunction with the security system to ensure the safety of the archives. . If it is an authorized file out of the library, the software will automatically record the out of library information and make statistics.
(3) Correspondence with the digital archive project: On the one hand, the digital information of the archive can be written in the label, so that during the adjustment and return of the archive digital process, only the label can be scanned. Missing scan. On the other hand, the label information can be connected to the archive management software through the interface program. When using the archives, the archives that need to be adjusted are retrieved through the archive management software, and the system will directly send the information of these archives to the terminal, and the warehouse staff will use the terminal. You can directly find the files in the archives warehouse to realize quick and accurate file adjustment. If cooperated with the smart file rack, this information can realize that the file rack automatically opens the rack where the file is located. The file adjustment personnel can find the required file in the rack according to the indicator light of the smart file rack, and the whole process can be completed in 10 seconds. Secondly, the access control system that reads the label information can ensure that the files will not be taken out of the file lending room during the borrowing process to ensure the safe use of the files.
