| With the continuous development of urban rail traffic, Automatic fare collection system(AFC) has a huge development as a automation system which can achieve the automatic ticketing,and automatic ticket,and automatic charge,and automatic statistics.Meanwhile, with the continuous breakthroughs of the research and development of the AFC system equipment, the AFC system equipment is a step toward the road of localization. Ticket Amending Machine as a automatic equipment which can achieve buying exit ticket and updating ticket,will further promote the development of the AFC system and achieve fully automated management of the subway operator.The study of this paper is under the background of Wuhan Metro Line2project.At first,this paper describes the design of the overall structure of Ticket Amending Machine,according to Wuhan Metro’s specific needs.And the system is divided into operational modules and maintenance module,according to Specific functional requirements analysis.And this two major functional modules has been detailed division.Then this paper describes detailed process design and data flow graph about four big business which is that stored value card recharge,and inspection card,and buy exit ticket and updating card in the operational modules.And the four big business has been divided into waiting for the card status,and waiting for the coin state, and waiting for a continue coin state, and card payment status, and transaction status, and refunded state and finish transaction status by using the state mode.In the development process of the entire system,this paper evaluates the design scheme of underlying module by using Analytic Hierarchy Process(AHP).And the system takes ticket selling module as a example,to detailed describe the application of AHP.Moreover,the system also takes the reader module as a example,to describe the specific use of Dynamic library.Last,the author developed the automatic Fare Adjustment machine system by using C++programme language. |
