Research On Key Technologies Of Management System Of Logistics Information

Logistic information has the feature of large quantity and miscellaneous content. Nowadays the logistic information has existed many kinds of defects, in order to adapt the requirement of modern logistics, this thesis brings up a management system of logistic information based on the technology of RFID . It is a system which deposits basically information into the replying device and develop a management system for RFID responders.At first, on the basis of the present research state of logistic information and the RFID technology, It designs the whole frame. It does research from several aspects such as function, component parts, applied domain, at the same time. It analyses the problems of loading and the requirement of security and brings up corresponding solutions.The second, this thesis brings up signal processing and the code techniques of the RFID applied system. Between the equipment of RFID and the RF card it corresponds by the way of inductive coupling, the reading and writing effect of the system such as distance, the rate of making error and stability are associated with the feature of this wireless information passage.The third, it puts forward the secure theory of the RFID applied system .In order to defend the attack, the RFID system usually uses the way that inputs symmetry with each other of the RFIC Tag and data encryption, and the mistake that making during the process of data encryption, it also associated with the code to enhance the reliability and security.The fourth, it designs a against impact plan based on P-Aloha treatises for the research of against impact, it also makes a series model and obtains a mathematical equation among the probability of repeating, the number of tags, the Poisson parameter of the sending process of one tag, and the size of the reader's buffer._ the process .moreover, it uses Matlab language to analyze the model, verified the accuracy.The fifth, it integrates the former research of the whole process, designing and performing the system comprehensivelyAt last, it summarizes the primary work of the whole thesis, and it also creates outlook and designs for the next work through the research of hardware , software and against impact technology.
