摘要
简述了我国铁路货运管理的现状,并根据802.15.4工作组定义的ZigBee无线连接技术的极低复杂度、低成本、低功耗和低速率和可选的安全性的优点,提出了一种基于无线网络技术的两层无线网络组网结构。该网络由安装在货物车辆上的无线终端节点、货场中的中心节点(中继节点)和安装在控制室的网络中心节点构成,可实现货物的动态实时管理控制。
This paper summarizes the present situation of our country railroad freight transportation management,and proposes one two-layer wireless network structure based on wireless network technology according to the low complexity,low cost,low power loss and low gear rate of the ZigBee wireless connection technology which defined by the 802.15.4 work teams.The wireless terminal node, which installs on the cargo vehicles,the central node （relaying node） in the freight yard and the network central node in control room constituted the whole network,and realize the freight real-time supervisory control.
