Design Of LON-based Campus One-Card-Through System Project And Web Database

This paper gives the completed and detailed idea of design of the whole project and system's database, using the ascendant net-conncting characteristic of lonworks fieldbus and merit of RFIC (Radio Frenquency Identification Card).The paper includes two major parts, namely: design of the whole system project and design of the system web database, and totally four chapters. At first, in the introduct of the paper, I expatiate the develop status, deficiency and its background of one-card-system contractedly. Next, in the second chapter of the paper, I expatiate the characteristic of lonworks fieldbus technology, and its net-connecting characteristic; Thirdly, the paper dwells on project design based on Lonworks fieldbus technology, puts forward a new network struction. and demonstrate it's feasibility from system Real-time, safety, expansibility and so on; forthly, the paper gives the design of hardware and software of card reader and access controller; at the end, namely, the fifth chapter of the paper, I give the design of the system web database in detail, according to the standardized design step.Totally, the system deals with every aspect of campus life, such as restaurant, hospital, school comsumption, library, access control and so on. Aiming at replacing student card, ID card, library card and computer-handling card, realizing the dream of throughing campus using one card.
