摘要
城市轨道交通自动售检票(AFC)系统是一个异构分层系统,在应用中集信息管理与设备监控于一体,存有大量的数据交互与使用。针对该系统二进制编、解码消息带来程序代码量大和可读性差的传统做法,研究和应用外部数据描述(XDR)技术实现AFC系统中跨异构平台的交互数据的编、解码方法,并以设备控制参数表为例,详细描述了在Java和C编程环境中的实现步骤。
City rail transit automatic fare collection(AFC) system is a heterogeneous hierarchical system,which integrates both information management and equipment monitoring in applications,where there are massive data interactions and usages.The traditional binary encoding/decoding messages approach of the system brings about too many programming codes that further cause poor readability.The paper studies and applies external data representation(XDR) technology to realize a encoding/decoding method for interactive data across heterogeneous platforms in AFC system.In addition,taking the equipment control parameter table as example,the paper describes in detail its implementation steps in Java and C programming environments.
