基于XML的网络型信号灯控制设备的通讯标准

Criterion for Network Traffic Controller Based on XML

城市交叉路口信号灯控制设备来自不同的制造厂商,通信接口标准各不相同,很难满足ITS对城市交通协调控制的需要。为建立城市信号灯系统中的电子数据交换基础,实现交通控制系统跨平台集成,应采用通用电子数据交换格式建立相关开放的技术标准。文章介绍了应用扩展标记语言(XML)建立信号灯控制设备数据交换标准的过程、方法,提出了开放式信号灯控制信息交换的标记语言SignalML。

There are many kinds of traffic controllers, which are made according to different communication interface criterions in urban traffic intersections. These controllers cant meet the needs of ITS in urban traffic coordinate control. In order to set up the foundation of electronic data interchange in urban traffic light system and realize the platform integration of traffic control system, the relevant and open technical criterions should be made by using the common format of electronic data interchange. This paper introduces the process of making the criterion for traffic controller data-interchange based on XML and puts forward the markup language SignalML.
