In order to improve the efficiency of automatic passenger-portable baggage sorting in the airport security check and ensure the sorting accuracy, this paper designs an automatic baggage sorting system. In hardware, RFID is used to realize the location and identification of passenger-portable baggage sorting. Meanwhile, the automatic reuse and transfer of pallets are realized by sensors and conveyor belts. For software, a demo software for processing information is proposed. Besides, the accuracy of baggage identification is guaranteed by a series of anti-cross reading and miss reading measures. Finally, the feasibility of the system is verified by the case study. © 2020, Politechnica University of Bucharest. All rights reserved.
