1. Concept
Conceptually, RFID is similar to barcode scanning. As far as barcode technology is concerned, it attaches the encoded barcode to the target and uses a dedicated scanning reader to use optical signals to transfer information from a bar magnet to scanning and reading. RFID uses a dedicated RFID reader and a dedicated RFID tag that can be attached to the target, and uses frequency signals to transmit information from the RFID tag to the RFID reader.
2. Structure
Structurally speaking, RFID is a simple wireless system with only two basic components. The system is used to control, detect and track objects. The system consists of an interrogator and many transponders.
3. Application status
Initially in the technical field, the transponder refers to an electronic module capable of transmitting information and replying information. In recent years, due to the rapid development of radio frequency technology, the transponder has new terms and meanings, and is also called a smart tag or label. The reader of the RFID electronic tag performs wireless communication with the RFID electronic tag through an antenna, which can read or write the tag identification code and memory data. RFID technology can identify high-speed moving objects and can identify multiple tags at the same time. It is quick and convenient to operate. The rapid development of RFID technology is of great significance to the progress of the Internet of Things.
Four, typical applications
RFID readers are also divided into mobile and fixed types. At present, RFID technology is widely used, such as: logistics and supply management, manufacturing and assembly, air baggage handling, mail/express parcel processing, document tracking/library management, Animal identification, sports timing, access control/electronic tickets, automatic road toll collection, all-in-one card, plastic pallets in storage, turnover baskets, etc.
5. Application of Smart Archives
Based on the advanced and complete RFID system structure, make full use of the readable and writable, high reliability, high storage capacity, and customizable characteristics of RFID technology, and fully consider the actual needs of customers and guarantee the existing infrastructure To the scalability and openness of the system, the RFID archive electronic tag is used as the information carrier and the RFID middleware is used as the bridge to realize the organic integration of the RFID system and the archive management system, simplify the archive management process, and improve the archive management. The efficiency of this system provides more user-friendly and convenient file borrowing and returning services for file inquirers, and at the same time realizes file inventory, anti-theft, one-time batch loan and return, and one-time batch storage.
File management includes intelligent librarian workstations, intelligent positioning inventory vehicles, intelligent entire library inventory vehicles, intelligent access control systems and remote intelligent monitoring systems, combined with file RFID tags and shelf RFID tags, to achieve a complete RFID smart archive management solution.
