AFC System in Urban Rail Transit

Abstract

Now, the development of China's urbanization process faster and faster, the domestic first-line second-tier cities showed rapid development of rail transit construction. AFC (Automatic Fare and Collection, AFC) system is based on the computer as the core, communications, networking, automatic control technology, mass transit ticketing, ticketing, passenger statistics, data clearing, fully automated billing and management Control System. Wherein the vending machine is the AFC system, the most important part of its efficiency and reliability of urban rail transport will have an important impact.

This paper first describes the role of the AFC system and its components, research status of development, leads to the subject of the significance of the topic. Then analyzed the functional requirements of the structure and composition of an automatic vending machine, vending machine proposed design based on ARM. Design of vending machine according to the paper requirements and overall program design, with powerful data processing and network communications transmission capacity HMS30C7202 microprocessor, interface circuitry for key vending machine structural design. Protues use software to complete the schematic design and drawing, and then for the relevant technical summary of communications required Linux operating system involves doing a simple exposition. On the basis of embedded development on the vending machine for research and design, we completed the basic functions of an automatic vending machine, comprising: a passenger touch screen, identify the authenticity of the currency, a single ticket information read-write, upload and save data Wait. Enabling the system to an Ethernet-based data communication, provide a good foundation for further development and application.
