Nanjing Subway Ticket Vending Machine Payments And Subsystem Design And Development Of The Change

Throughout the history of the development of foreign economically developed cities’ urban mass transit system, Only to develop a large amount of passenger traffic transportation system can solve the problem of medium-sized cities’traffic jam in our country. Automatic fare collection (AFC) enables intelligent passenger ticket and the ticket at each station. Ticket vending machine (TVM) can interact with passengers, Sell one-way ticket, receives cash from passenger, Give change and other functions, So TVM is one of the most important terminal equipment in the AFC system.First, this paper introduces the subway AFC system. Then discuss in detail the current situation and development trend of domestic and foreign research AFC system, Next based on the specific needs of Nanjing Metro Line10TVM ticketing system to layered design of the system, Afterwards TVM system is divided into payments and change subsystem and sale single Journey Ticket subsystem. This paper is to design the overall module of the payments and change subsystem, To complete the payment and change subsystem main module’s processes design, To design and implement the Banknote Acceptor (BIM) module and the Coin Handle Machine (CHS) module. Finally, Testing the function and performance of each module separately, then Continue to test with the sale single Journey Ticket subsystem integration and simulation on the prototype, and then carried out a detailed analysis and summary for the test results.
