【摘要】 针对交通信息采集系统存在系统庞大复杂、监测区域重复或者采集信息缺失、数据种类复杂且占用存储空间大、缺乏覆盖全路网的信息采集技术以及缺乏对道路单个车辆的信息采集等问题,提出将RFID和WSN融合的系统。阐述了当前交通信息采集系统的研究现状和存在的问题,构建了适用于交通环境的WSID系统;从必要性和可行性方面分析了该系统的可实现性。结果表明:搭建WSID组网系统对于解决当前交通信息采集系统的某些缺位、监测区域重复或者采集信息缺失、数据种类复杂且占用存储空间大、缺乏覆盖全路网的信息采集技术等不足是可行的。更多还原

【Abstract】 Traffic acquisition system has large complexity monitoring area duplication or missing information data types complex storage space large storage space lack coverage of whole road network information acquisition technology and lack of road single vehicle. Information collection issues,Propose a system that integrate RFID system and WSN system. Firstly,this paper expounds the current situation and problems of current traffic acquisition system,builds up WSID system suitable for traffic environment,analyzes its feasibility from necessity and feasibility. The result shows that constructing WSID networking system. It is feasible to solve some shortages of current traffic information acquisition system and lack of monitoring regions or missing information collection data types complex storage space large storage space lacking coverage of whole road network information acquisition technology.更多还原
