Abstract
A book sorting method based on RSSI signal values of RFID tags, including the following steps: reading book RFID tags placed in books by using an RFID device, wherein each tag signal includes: an EPC number EPC of the book RFID tag, the RSSI value r of the book RFID tag, and the time t of reading the book RFID tag, and three attribute values corresponding to one book corresponding to one time are marked as a record; classifying books with the same EPC number of the tags as a category, obtaining a curve chart of the RSSI values of the category of book RFID tags according to a time sequence, and preprocessing the curve chart; and establishing a model; and obtaining the position sequence of each book RFID tag according to the model so as to sort the books.
