基于CORBA和XML的交通信号控制系统

交通信号控制系统由不同制造厂商的控制设备和操作控制软件平台组成,而且,数据来源多元化.在交通信号控制系统中要求数据流传输快速、精确、完整和安全,由于设备的通信接口各不相同,使控制系统内部的不同控制单元之间很难进行信息交互和共享,因此,要求一种统一的结构性描述语言来组织数据.对基于COR-BA结构和可扩展标记语言(XML)的交通信号控制系统的研究,提出了分布式交通信号控制系统的结构框架和开放式信号灯控制信息交换的标记语言SignalML,为目前交通信号控制系统的异构平台和数据交换引发的问题提供了有效的解决方法.

The Research of Traffic Signal Control System Based on CORBA and XML

Traffic signal control system consists of different control equipments from different manufacturers and different platforms of control software. The basic requirement of data-interchange is quick, exact, integrated and safe during transmission. It is difficult to use and share data among different control units because of different communication interface standard. We should build a uniform structured language to organize data. The paper discusses the traffic control system based on CORBA and XML, and then puts forward the distributed frame of traffic control system and markup language-SignalML for opened signal control data-interchange. An effective method to solve the problems of multi-frame platform and data exchange is put out.
