Analysis The Actuality Of Campus's E-card And Designing-Actualizing The Improved Project

Nowdays with the high-speed development of information, more and more information are exchanged and managed in digital form. Along with the rapid development of smart card technology and universal promotion of computer application, the Campus Information Management introduces IC card applications have become a trend, and the application of IC cards are also moving from unilateral application (such as canteens charges, library lending ) to the campus E-card direction for extension and development, called "E-card ". In the application, the inadequacy of campus E-card system is exposed after several years of construction and use. Thus, according to actual needs, the optimization the campus E-card system came into being on the issue.The E-card system is gathering financial services, payment transactions, identity verification, business management. The system uses the advantage of smart IC card can be multifunction and offline transactions, and other advantages. With the support of Campus network, the E-card can be uses in everywhere in campus, has consumption, identity, personal information enquiries, and other functions, achieving the original intention——"one card in hand, through the campus, one card pass ,one card with multi-application " .First, this paper, gives a general introduction of the development of smart card, and the necessary of card system's arising and booming development; then gives a detailed analysis of the use of the campus smart card system at home and abroad at this stage, and the campus card foreseeable future trend of development. At last this paper also detailed introduces critical technologies of the Campus E-Card System.This paper is based on the investigation of domestic use of the campus E-card, and in conjunction with the problems that the Southwestern University first-phase campus E-card system is faced. Through depth research of the problems, analysis and testing, find the root of the problems, and design improvement scheme of the campus card system. The main goal of the improvement is to reduce the work pressure of the core network equipment, improve network transmission efficiency and lower terminal equipment offline rate, ultimately assure the real-time reconciliation function of the financial statements, raise the quality of terminal maintenance, optimize the water control subsystem's Money conversion methods,inorder to make it reflect the true ownership of the funds.This paper start with the analysis of the Southwestern University campus e-card system connect with the actual use, such as transaction records abnormal, terminal equipment maintenance difficulties, and so on, through the Campus Card System, from the core switch access to the terminal, from behind the server to the front desk management software,take a detailed study of the unusual circumstances, as well as a comprehensive analysis of final solution - to improve Southwestern University Campus E-Card System. After full feasibility studies, we have chosen three problems——to be resolved terminal maintenance, data transmission efficiency and water control subsystem funds uncertain attribution , that direct impact on system operation crucial issues, to carry on a detailed analysis and research. First, carries on the detailed analysis of the system present situation, then determinate system improvement demand analysis. According to the high Off-line rate of the campus E-cord system's terminal equipment and the difficulty of those terminal's maintenance, we proposed the design program to transform network construction and design the terminal monitoring system. In the project, first frame the terminal device monitoring system's function and the module has carried on the design, it has realized the main function and the database foundation based on the designed model. Based on the physical demand of the system on the network, proposed abandons the star network architecture, uses the core layer + gathering layer +connecting layer as the network architecture, reduces pressure of the core layer's routing and repeating, guarantees the entire net's transmission quality. The article also aimed at the problem, which is the water control subsystem fund flow direction is not real, proposed entire account transfer pattern's water control subsystem idea, and has designed the improvement program, has realized the main function. Finally, this paper elaborates the superiority of the improved system based on the improved Southwest University Campus E-card system's service condition.
