Design And Development Of The Control System Of The Subway Internet Ticket Vending Machine

With the continuous development of urban rail transit in China,AFC(Automatic Fare and Collection)system,as an automatic system that can realize the functions of ticket selling,ticket checking,fee collecting and statistics,has been applied in many urban metro systems.At the same time,as a new payment method,mobile payment has been widely used with its advantages of convenience,speed and security.It also provides a new way of payment for AFC system.As the key equipment in AFC system,how the Ticket Vending Machine(TVM)should adapt to the current trend and realize the function of mobile payment has become the research focus of AFC system.This paper is based on the research and development project of Internet Ticket Vending Machine(ITVM)in Nanjing Metro.Firstly,the development and research status of AFC system at home and abroad are described.Secondly,the control flow,data flow and overall framework of the control software are designed.Then based on the analysis of the difficulties in the combination of mobile payment and ticket vending machine,this paper puts forward a combination scheme of mobile payment based on Metro payment platform,and designs the interactive process of mobile payment and the network interface of Metro mobile payment platform.On the basis of the foregoing,the detailed design and development of the Internet ticket machine control system is realized by using object-oriented idea as the design method,using C++ as the development language and Visual Studio 2013 as the development platform.At the end of this paper,the control software of Internet ticket vending machine is tested,and the results meet the expected design objectives and performance requirements.It has passed the acceptance of Nanjing Metro.At present,the equipment has been officially put on line.
