摘要
智能交通系统将信息技术、电子控制技术及网络技术等高新技术综合应用于运输管理体系。ZigBee作为一种新兴的无线传感器网络,具有功耗低、成本低等特点。介绍了在小区域智能交通模拟平台上使用无线传感器网络的实例,建立了信息发布/订阅和信号控制系统。重点介绍了系统的节点硬件、ZigBee协议的数据传输以及两个子系统的软件设计。
Intelligent transportation system （ITS） is a transportation management system using hi-tech such as information technology, electronic control and network tech. ZigBee is new wireless network technology, having advantages of low-power and lowcost. On the small region intelligent transportation system, an application of wireless sensor network （WSN） was introduced and a system of information publishing/subscribing and signal controlling was built. The node＇s hardware, data transmission of ZigBee and the software of two sub-system were introduced in details.
