| Along with the uninterrupted development of rail transit, the research of the AFC (Automatic Fare Collection) system of city rail transit is also in the incessant research process. The AFC system is base on the technology of computer, communication, network, automatic control. It is an automatic system to achieve the process of ticketing, ticket checking, accounting, Stat., clearing and management.Central computer system consists by the central computer server, the central local area network, data storage systems, line center system, the report subsystem, communication subsystem, coding subsystems, processing systems and other accessories. Central computer system communication backbone for data upload and download, on line monitoring all equipment within, to realize the operations, ticketing, finance and maintenance of centralized management capabilities, including operations management, equipment management, traffic management, and ticketing, financial management, report management, maintenance management, project management, data management, log management, audit management, security management. This article include follows three parts, the first part is urban rail transit automatic fare collection system needs analysis, including comparing the current situation at home and abroad, the needs of our current system, the second part of the overall automatic fare collection system architecture, including physical structure, logical structure and functional structure, the third part shows the implementation of automatic fare collection system solutions, including data management solutions, device management, traffic management solution, model management programs and revenue management program.This article first analyzes the requirements of the central computer system, then implements the overall design of the software system and hardware system of the wire center as well as the detailed analysis of its key components, and finally puts forward the implementation scheme. |
