The Transmission Processing of Giant Data in AFC System

自动售检票系统是城市轨道交通运营中关于售检票自动化及其交易管理的综合信息系统。基于套接口通信技术和共享内存技术,提出把自动售检票系统中各类运营管理和票务交易数据按其类别和预设优先等级划分,并形成4种通信传输规程,很好地实现了自动售检票系统中数据的及时传输,有效防止了票务交易数据传输延迟问题。

AFC（Automatic Fare Collection）is a comprehensive information management system concerned with automation and transaction management for ticket vendor and checking in urban rail transit. Based on the technique of socket communication and the common memory, this paper proposes an idea of multiple transmission queues that are produced by classifying all the data about operation management and ticket transactions of AFC system in terms of their properties and the pre-determined precedence grades, and designs four regulations for communication transmission, by which AFC＇s data can be transmitted in time and the problem of transmission delay for ticket transactions is effectively prevented.
