물류 응용을 위한 PDA 기반의 RFID 인식 시스템의 설계 및 구현

Abstract

Ubiquitous computing provides the convenience of the free connection to computers in any place and with any device to obtain and use the information and offers a whole range of the supplementary service with the wireless connection to the Internet. Recently, with the advancement of the technology for bar-codes and RFID(Radio Frequency Identification), the appearance of the business models with the special code capable of storing highly-condensed massive data and conducting the encode authorization, as well as linking to both wired & wireless Internet is being applied to areas like the credit card and various payment services. But the high price of RFID chip and the intervention of other frequency can be a technological problem that can hinder the usage. And the expensive royalty for the 2nd dimension bar-code also has to be paid for the import, as is the same case with reader and software that complies with the standard. In an effort to figure out the problems and seek ways to promote the application, this dissertation compares and analyzes the features of the recent technology regarding the cases where the second dimension bar-code and RFID was applied in the Ubiquitous environment and where it can be applied In addition, it, as a swift, accurate, safe and integrating logistics management system that handles the input and the output of the basic information about the products by attaching tag on the products, such as clothes, shoes, designs, and realizes the software capable of the understanding in the embedded system environment with RFID reader and the tag, in order to develop the system that can dramatically enhance the customer service while keeping the logistical cost to the minimum. And as a logistics management system built from the establishment of the module and the module capable of parsing the location information of GPS and the database on server's side, it realizes the functions such as the automatic inspection, the accurate stock counting, the identification of the products, updating of the information, checking of the replenish and the withdrawal of stocks, prevention of the theft, etc.
