Design And Implementation Of Automatic Gate Machine In AFC System

As a important part of urban rail traffic, automatic fare and collection system does the work of tickets selling and tickets collection when passengers enter or exit the station efficiently and accurately in unattended manner. In automatic fare and collection system, because automatic gate machine closely relates with operator and revenue management, it becomes the most important part of the whole system.After analyzing the basic function of automatic gate machine, the paper gives the detailed system design and implementation from the two aspects of hardware and software.In the aspect of hardware, automatic gate machine constructs system in system integration manner. First of all, the analysis is started against all components of system, the functions and performance will be analyzed, then, with the results of the analyze, the selection program of main control unit and pass controller and IC card reader and writer will be given. Finally, the hardware connection will be given.In the aspect of software, the software structure of system will be divided into four module by analyzing the business function, the modules are operator module, monitor module, maintain module and communication module, and the design is make with modules. The design and implement of the operator module and communication module is the important point of exposition.After the design and implement of automatic gate machine, the function and pressure test will be given. In the test result, the function of the automatic gate machine of designed and implemented is complete, and the running is stability, the design target is implemented.
