Research And Realization Of The Individual Medical Information System Based On RFID

This thesis researches the realization of personal medical treatment information system based on RFID. RFID(Radio Frequency Identification)system is an automatic identification technology that has been developed since 1980. Compared with barcode system,optical character recognition technology, biometric identification technology,integrated circuit card,RFID system has particular no-contact,anti-interference and environmental adaptability characters,so it becomes one of the most excellent automatic identification procedures that are applied in many fields. Firstly, the basic principle of RFID is introduced. Secondly, based on the analysis of the operation principle of the inductance coupling radio frequency intelligent card and its reader/writer,radio frequency interface circuit is designed by using RI-R6C001A chip. Communication interfaces, including RS-485,with PC computer are designed. The understratum software is developed by Keil C. The communication software is implemented both on card reader/writer and on PC computer. The data such as management information,application data, etc can be transmitted from PC computer to card reader/writer, and some relevant records from card reader/writer to PC computer. Thirdly, concerned with medical treatment actual status, this paper discusses the software of above machine, and present above machine management system according to Visual Basic 6.0 to fulfill such operation with data like saving, analysis, maintenance, query and statistic and report forms printing. Finally, this paper summarizes the design, and present some aspects need to improve forward in personal medical treatment information system.
