The Design And Implementation Of The Subway Ticket Vending Machine Software System

As China’s urbanization, the construction of large and medium-sized urban rail transit was rapid development momentum. Automatic fare collection system (AFC system), is a centralized control by a computer-based communications, networking, and automatic control technology, railway ticketing, ticketing, billing, charging, statistics, clearing the whole process of automation systems. Ticket vending machine (TVM) is the most frequently used and most demanding terminal equipment, and closely related to its operations and revenue management. The smooth line and the stability of the ticket vending machines will have important implications for the construction of the Metro Rail Transit.My personal work focuses on the classification of the ticket vending machines, function, working principle, working methods, equipment, components, analysis of the hardware architecture and software modules. The design of the structure of the automatic ticket machine software system, from a functional point of view the system is divided into five modules:master module, coin module, banknotes module, distribution module and maintenance module. This thesis describes the design and implementation of the master module, maintenance module and distribution module function finally, the system test program, test results are analyzed and suggest improvements direction.This thesis designed a function of the system of automatic ticket vending machine software system, play an important role in the automatic fare collection system, have a great effect on the overall performance and efficiency improvements; great reference value for the design of an automatic vending machine, you can learn to design a more reasonable design method, to abandon the place of which the design of potential defects.
