Based On Key Technologies Of Rfid Field Health Service Information Systems Research

Internet and the rapid development of modern information technology for modern military contest injected new vitality, and the army is developing towards information technology, networking and intelligent direction. With the developing of modernization of national defence and militarization, our country more and more attach importance to the soldier's life and improvement of battle effectiveness, and in order to keep up with the innovation of informational war, the thesis brought up a management system of field hospital information based on the technology of RFID. RFID(Radio Frequency Identification)was an automatic identification technology ,with which data could be duplex transported contactlessly between reader and tag. The field hospital information system saved the basic information and wounded information of the soldier in the tag, and dealt with those information by the fixed reader or the mobile reader, the system improved the work efficiency and rescued more wounded soldier's lives.The main results were as follows:1. On the basis of the present research state of field hospital technology and the RFID technology. It designed the whole frame. It did research from several aspects such as function, component parts, applied domain, at the same time, it analyzed the problems of loading and the requirement of security and brought up corresponding solutions.2. In this thesis the correspondence techniques of the RFID applied system were brought up. Between the reader of RFID and the tag, it corresponded by the way of inductive coupling, the reading and writing effect of the systems such as distance, the rate of making error and stability were associated with the feature of this wireless information passage.3. It put forward the secure theory of the RFID correspondence system. In order to defend the attack, the RFID system usually used the way that input symmetry with each other of the RFID Tag and data encryption, and the mistake that was making during the process of data encryption, it also associated with the code to enhance the reliability and security.4. An against impact plan based on P-Aloha treatises for the research of against impact was brought, a series model was maken and a mathematical equation was obtained, 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.5. It integrated the form research of the whole process, designed and achieved the field hospital information system. Designed the frame of the system, and brought up the requirement analysis of the system, which mainly emphasized on the basic information, rescuing the wounded soldier, statistics of information; Because the whole system mainly managed information data, after finishing the analysis of the system, it designed the database; it designed the function, designed the programs, draw the program's flow diagram, code and debug, test; analyzed the system's performance form many aspects, such as security, reliability, adaptability, expansibility and so on.6. It summarized the primary work of the whole thesis, and it also created outlook and designed for the next work through the research of hardware, software and security technology.
