Localization of Pallets Based on Passive RFID Tags

As logistics industry is being grown, the saving of logistic operating cost becomes the key of efficiency in many fields of industries. The saving of cost is possible by improvement of processing mechanism efficiently. Simply, if the locations of stored freights are managed on a real time by a certain system, then the cost to find stored freight such as time and fuel of driving forklift is able to be saved. Therefore managing the location of stored freights is important approach to saving logistics operating cost. Therefore, this paper proposes logistics warehouse based on RFID ceiling tag that means RFID tags are attached to the ceiling of logistics warehouse. In our proposal, we use RFID technology to find the location of freights, not RTLS or GPS. Accordingly, adopting RFID technology which is contactless object recognizing system make it possible to automatically monitor and manage location of stored freight and processing status on a real time at relatively low cost in logistics warehouse environment.
