Research On The Distribution System And Technology Of Agricultural Supply Logistics Based On RFID

Along with the development of agricultural modernization, the agricultural supply logistics is becoming a bottle neck in agricultural production process. Modern agricultural supply logistics needs to provide effective management for agricultural production in its whole life cycle, including producing, transporting, storing and marketing. Radio Frequency Identification (RFID) is a new technology of Automatic Identification and Data Capture (AIDC), which has been successfully applied in multi-target track and identification. Its advantages, such as abundance of data information, high security of data, great ability of anti-EMI (Electro Magnetic Interference) and short recognizing time etc., particularly meet the requirements of agricultural supply management system.Taking the demand of agricultural supply logistics and the features of RFID system into account, the research designs a distribution system of agricultural supply logistics, together with its structures and functions, based on the computer controlling technology, the RFID data gathering technology and the platform of the existing network; subsequently, the dissertation illustrates the framework of the RFID subsystem.RFID is in charge of data collection and transfer in distribution system, its key technologies, such as tag-coding, data verifying, data correcting, and reader anti-collision, are lucubrated in the dissertation.The research focuses on how to design and realize the distribution system of the agricultural supply logistics. Its data model is established by notion design, logical structure design, which support a set of functions, such as in-warehouse management, ex-warehouse management, statistics and search, etc. This thesis also demonstrates some primary interfaces and the operation of this system. Finally, it takes agricultural seeds as an example to illustrate the flow of agricultural supply logistics management system.Based on the summaries conclusions of all research works, some suggestions and prospects for further researches are put forward.
