Based On RFID Seal System Design And Implementation

High-intelligent modern logistics transmission and warehouse management, whose development will promote the economy,the circulation of commodities and the mass consumption,are the basic guarantees of the development of national economy and the Internet of things. However, because of the defects of close reading,slow speed,small information capacity,difficulty of alter and being sheltered and frayed easily the bar code applied in the traditional logistics management has been hard to adjust to the development of modern logistics. Therefore it has been the common sense to most people to adopt advanced automatic ladder of management to realize the intelligent management of storage and effective logistics. Thus it can be seen that in the practical application the integration of RFID technique and the information system inside the company is the first problem to be confronted with and solve for the company to bring in the RFID technique. While what will be discussed in this thesis is that electronic blockade will replace bar code,which is to overcome the technical defect of logistics management system of bar code and improve the level of logistics management tremendously.The logistics system created in this thesis firstly insets the physical heat of electronic tag into the mechanical blockade,which forms a low-cost electronic blockade realizing data exchange through reader and computer that realizes the enquiryl,ocation,tracking and recognition of the goods through the Internet. The program based on RFID technique and combined real-time operation system of embedded chip,multi-sources and network data-based technology as its center creates a logistics system of low-cost electronic blockade in which technologies of low-power,communication security and data encryption are adopted. It contains features as below:small volume,non-touching automatic identification,large capacity of information storage,supporting fast reading,non-touching mobile identification and location,trailing management of long term and the ability to realize the goods trailing and information sharing around the world through the combination of the Internet with communication technology. The main research content includes:1. Introducing detailed basic knowledge about RFID,summarizing the domestic and overseas development of RFID and probing into the background, status and meaning of the research,the problems existed at the present stage and the research orientation in the future.2. Setting up a platform aimed at the reader and the experiment and design of electronic blockade,in which the platform mainly realizes the performance evaluation of the RFID,of which the most important is the argument of reading distance and choosing the appropriate antenna and finishing the design of the antenna through the analysis and comparison of different types of antennas.3. In combination with the building of the experiment platform and the design of the antenna above elaborating the design of the software in the detailed realization of the system and discussing the design philosophy of the software,the function of every part and the specific process of realization of every software task. The RFID in this thesis is designed for HuangShan Yili Company and its realization will provide a reference basis for the medium and small enterprises in China to adopt the RFID technology.
