An automatic and intelligent book checking and shelving robot based on the RFID technology, including an RFID system used for identifying book information, a controllable lifting device used for checking books, a navigation sensor for providing a locating navigation function and a four-wheel omni-directional mobile platform for driving the equipment to move. The present invention mainly uses the automatic identification technology and the radio frequency phase technology in the RFID technology, and the machine automation technology to realize an automatic and intelligent book checking and shelving function, including an automatic whole-library book checking function and an automatic whole-library book shelving function.

Automated smart book inventory and shelving robot based on RFID technology

A book placement posture identification method based on an RSSI signal value of RFID, including: step 1, horizontally moving to read the signal of an RFID tag placed in a book by using an RFID device; step 2, classifying triples with the same EPC number as a category to serve as the RSSI signal values of the internal RFID tag of the book obtained at different moments; step 3, preprocessing the data obtained in step 2; step 4, establishing a model to obtain a time-varying rule of the RSSI value of the RFID tag of the book; step 5, sampling data, training a classification model, and judging the placement posture of the book according to a model established according to test data and a classification model; and step 6, vertically moving to read the signal of the RFID tag placed in the book by using the RFID device.

Book placing attitude recognition method based on RSSI signal value of RFID

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.
