BOOK PLACING ATTITUDE RECOGNITION METHOD BASED ON RSSI SIGNAL VALUE OF RFID

摘要

A book placing attitude recognition method based on an RSSI signal value of an RFID, comprising: step 1, using an RFID device to laterally and movably read an RFID tag signal placed in a book; step 2, classifying triads with the same tag EPC number into a category to serve as an RSSI signal value, acquired by the book at different times, of an internal RFID tag thereof; step 3, preprocessing data acquired in step 2; step 4, establishing a model, so as to obtain a time-varying rule of the RSSI value of the RFID tag of the book; step 5, sampling the data, training a classification model, establishing a good model and the classification model according to test data, and determining a placement attitude of the book; and step 6, using the RFID device to vertically and movably read the RFID tag signal placed in the book, and using a sorting algorithm to finally determine the position of the book, and determining whether a result in step 5 is incorrect.
