In this paper the electronic recognition system based on internet of things technology for railway logistics is designed and implemented. The 4 level information transfer mode is used between RFID Tag, train carriage identifier, station yard identifier and computer sever. Radio communication is used between RFID Tag, train carriage identifier, station yard identifier. Wired communication is used between station yard identifier and station computer. The problems of information collision between multi-tags, long-distance transmission of information and communication interference are solved in this article. The experimental results show that the system is effective when the speed of the train within 120Km/h and it is applicable to the railway logistics.
