基于无线城域网的智能公交系统设计与实现


摘 要:针对现有智能公交系统存在的通信带宽有限、易产生信息孤岛、缺少实时路况等问题,设计并实现基于无线城域网的智能公交系统。该系统融合公交信息采集、运营调度、公交监管和综合信息发布平台。借助.NET对平台进行了三层架构部署,总结良好的软件设计及开发思路,并为平台运行所需的最终软硬件环境的实现提供了可行的解决方案。该系统经测试稳定性和实时性较高,能够满足公交运营需求。

  Abstract:Aiming at the common bottleneck of existing systems, such as limited communication bandwidth, information isolated, lack of real-time traffic condition, this paper designed and implemented an intelligent public transportation system based on WMAN. It integrated four platforms including information acquisition, transport schedule, transport monitor and information release. In virtue of the .NET, it deployed the platform by tropical structure, summarized an optimize software and exploitation idea, and that was the reasonable and consultable project comes for, the realization of final software and hardware for the platform running. The test turns out it can meet the need of public transportation management with its high stability and real-time ability. ......
