Nanjing Subway One-way Ticket Vending Machines Offering Design And Development Subsystem

With the growth in passenger rail transportation system, it is vitally important for efficient and reliable Automatic Fare Collection(AFC) system in urban rail transit system. The survival of the urban rail transit system will be effected by the realization of reasonable and quickly AFC. The ticket vending machines (TVM) is the key equipment of the AFC system, the good or bad software systems as well as directly affect the operation of the vending machine and user experience, coupled with domestic policy AFC system proposed by the state policy. Therefore, it is necessary to research the ticket vending machines system.In this thesis, one-way ticket sale subsystem of Nanjing Metro Line3, Line10and Line airport subsystem as the study background. First expounded the development and present research of AFC system at home and abroad that leading to the issue of the source of significance of the topic. Secondly, according to the logical structure and function of TVM,design the five layers of system software framework. In determining the one-way ticket sale subsystem as the research object, the function and performance of two targets are put forward. Then, using C++as development language, Visual Studio2010as development platform, Visio2007as design tool, the object-oriented thought as development methods, combined with XML technology, Windows message mechanism and system of data flow graph design and othe key technology to achieve the detailed design and development of system. Finally, at one-way ticket sale subsystem integrated with payment and change subsystem, finishing the system test and analysis under the ticketing and maintain interface by test cases, test results show that meet customer requirements.Finally, illustrates the defects and deficiencies of the system also exists, and puts forward some improvement methods as a reference for future research.
