Study On RFID Technology And Its Application On The Warehouse Management

Radio Frequency Identification (RFID) is known as a contactless automatic identification technique. Featured with the unique contactless and simultaneous multi-object identification, this technique has been widely used in purchasing and distribution logistics, transportation and anti-counterfeiting areas.The first part of the thesis aims to introduce the automatic identification technique and development of the RFID technique. The definition of RFID, its classification, advantages and typical application are summarized. The function and mechanism of the main system components, which include the reader, the electronic tags and the middleware between these two parts, are described in details. Two methods distinguish the RFID systems, one based upon inductive coupling and one based upon backscatter coupling. We reviewed the data coding and check technique and did in-depth research on the anti-collision technique.Based on the above knowledge, an optimized warehouse management system based on the RFID technique are developed and discussed. The prototype of core component, hand-held electronic tag and barcode read & write system, and system software are designed and developed. Through combining the RFID technique with the barcode and utilizing the omni-directional monitoring and management of the warehouse, the RFID solution for warehouse management improved the precision of the storage information and realized the real time automatic warehouse management.This system is the best solution for medium and small warehouse.
