The Research And Realization Of Intelligent Card Issuing System In Oil Sale System

Chinese economy is developing quickly these years. The occupancy of vehicle increases sharply accordingly. As an important service in commodity circulation, oil service becomes more and more important in people's daily life. Though developed for some time, the main payment method in oil service is still in traditional way, such as cash, oil ticket etc. This obsolete actuality not only causes many incommodities for consumer, but also brings big difficulty for gas station. In this situation, using intelligent card in oil sale system can be a perfect solution. As a maturely electronically payment method, intelligent card has the characteristics of high security, excellent authentication, easily take and use. It totally satisfies the requirements of oil sale application.As a subsystem, the single gas station intelligent card issuing system in this paper is belonging to the intelligent card oil sale system. This system can issue the blank card into different types of card, such as main card, PSAM card, and oil sale card. It also manages and maintains these cards. The difficulties of the system are communicating with the Card Operation System (short for COS), establishing files in COS, reading and writing relevant files, through serial port card-reader. The emphasis of system is insuring the safely use of oil sale card.Through analyzing the actuality, this paper introduces the purpose and meaning of intelligent card issuing system firstly. Then, according to actual requirements, the paper explains the material architecture and function division of the system.After introducing the transport protocols, the paper detailedly explains the system's difficulty-the design of file structure in card operation system, which includes logical structure design, relevant file folder design, operation instruction about relevant application etc.The paper introduces the system's emphasis-the design of system's security module, in particular. It includes the design of security structure, the calculation and management of the code, latent attack and solution and so on.At last, the paper summarizes the whole system. The merits and disadvantages come out after comparing with similar system, which points the aspect of amelioration.
