The Design And Implementation Of Radio Frequency IC Card And Its Read-writer

With the development of supply chain technology, the mobile multimedia terminal device comes to be an important development direction of this domain. And in the future, supply chain multimedia terminal must implement more functions to use new technology of supply chain. For the equipments to collect supply chain's communication, data's identification and read-writing is its most importment functions. The background of this thesis is the project of "The Research of Mobile Supply Chain Smart Terminal Device and the Development of Original Sample". This thesis designs and develops Radio Frequency IC Card and its Read-writer in Mobile Supply Chain Smart Terminal Device. For the project's needs, this paper designs and develops the core software and hardware technique of Radio Frequency IC Card and its Read-writer in RFID system. This paper first introduces the RFID system's composing characteristics and application techniques. Basing on the characteristics of contactless RF IC card, this paper then stresses to analyse and develop the system's hardware circuit. This paper first designs the function module and hardware circuit with low cost and miniaturization, then analyzes and establishs the Radio Frequency IC Card and its Read-writer's circuit module from the physical composing. This paper goes deep into the exploitation of RF antenna, which is a key technology of RFID system, and presents the system's practical RF antenna, then designs and empolders the system's Demo hardware circuit. After giving the software designing truss to read or write data and to control the IC card, this paper explains the system's software programme flow. Then this paper designs idiographic validation and testing project of the system. Using the testing tools, this paper describes the implement and the test process of each module in the system, validates and tests the system's functions, then gives the testing example of the signal's receiving and emitting. At last, a sum-up and expectation of the project's work is listed.
