Based On Arm Processor Of Rfid, Speaking, Reading And Writing Research And Implementation Of Software

RFID, radio frequency identification technology, is a non-contact automaticidentification technology which is based on the principles of radio frequency. As a newgeneration of automatic identification technology, RFID is widely applied in thesecond-generation ID card,city cards, and the lending systems of libraries.At present, the RFID technology is at most used in the low-frequency andhigh-frequency products. However, the latter ones are at the very beginning of theirdevelopment. They are mostly imported with extremely expensive prices and tight seals.In order to make some useful explorations and researches, the researcher managed tostudy and improve the present RFID products in this thesis.At first, the USB outlets are analyzed with the usage of the packet-capturingsoftware; the facility and its driving mechanisms are identified. Next, the systems areestablished and transplanted in the development board; the simplified and practicalinducing driver programs and parts of the driving programs are developed; the root filesystems are written up; the Qt banks, the touch screens, and SQLite databases aretransplanted. Then, EPC C1G2label agreements are studied; the realization of programfunctions is planned; and the models are divided up. Finally, the application programinterfaces are designed through the embedment of Qt environment in the personalcomputers.In the end, the whole software frameworks are established in the developmentboard. The major functions of RFID facilities are realized. Throughout the systematicaltests, the new products can meet the demand for individuals.
