Reader is the information control and processing center of intelligent bookshelf, which realizes the collection of book label information and data communication. The antenna is a unit radiating magnetic field energy, and the bookshelf antenna is in the form of array, which provides effective range control for the detection range of the bookshelf and improves the detection success rate. In order to accurately locate the layers of the bookshelf and realize the time-sharing switching of antenna groups on each layer, the application of multiplexer on the one hand enables multiple antenna groups to use one reader, and at the same time reduces the application cost. The intelligent bookshelf system and the book management software system need real-time data communication and are controlled by the book management system. After the RFID module collects the book label information, it transmits a lot of book label information to the book management system.

The electrical system of intelligent bookshelf is basically composed of reader, controller and antenna.

Reader: It is the core equipment of the intelligent bookshelf, which completes the functions of label recognition, communication and bookshelf control. Communication supports TCP/IP Ethernet protocol, and the bookshelf unit communicates with the library system.

Controller: complete the antenna control and positioning of each layer of the smart bookshelf.

Antenna: The antenna is the key unit of smart bookshelf to detect electronic tags, which determines the detection range of tags.
