Research Of Prison Management Information System Based On Rfid Technology

Radio Frequency Identification technology is a branch of automatic identification technology, a variety of technologies has appeared in the development of automatic identification technology, and these technologies have their own advantage, but RFID technology has the most competitive advantage with spacious application market and development space.Radio frequency identification technology is a kind of non-touching automatic identification technology; it has the characteristic of identification work without human intervention, bulk long-distance reading, low requirements on the environments, long service life, high reliability, data can be encrypted, stored information can be changed convenience and so on. The basic principle is based on the space coupling of RF signal (inductance or electromagnetic coupling) or the transfer characteristic of reflection, then to achieve the automatic identification of identified objects and get the related data. RFID technology is based primarily on large scale integrated circuit technology, computer hardware and software technology, database technology and radio technology.This paper is set in prison places, applying RFID technology to the modern management of the prison, and according to the actual needs of the prison places, designs a kind of prison management information system based on active RFID technology. The system is mainly used for the prison staff for effective management, which not only reduces the intensity of the work of managers, but also maximizes the protection of personal safety of staff members and criminals.First of all, this paper introduces several major automatic identification technologies based on the application fields and specific feature of automatic identification technology, and these technologies are analyzed and compared in detail, focuses on the advantage of RFID technology. Then the composition, trait and classification of RFID system is analyzed, the basic working principle of RFID system is introduced. Specifically, it focuses on the key technologies of RFID system:anti-collision technology and positioning technology. In addition, it summarizes the conceptual design of prison management information system, and realizes software functions of the system. Finally, conclusion is discussed in the end of this paper.
