基于 NFC 的高速公路异常事件预警系统设计

摘要

论文针对频发的高速公路交通异常事件问题，借鉴通信技术、GPS 定位技术，提出了基于 NFC 技术和 An-droid 技术的高速公路交通异常事件预警系统，给出了预警系统的总体架构，并分别对系统的 Android 客户端模块、预警装置模块和服务器端软件模块进行了设计，最后对系统功能进行了测试，结果显示，系统可快速、有效地发现异常事件的时间和地点，并做出相应的处理对后续车辆进行预警和诱导，从而减少次生事件的发生。%In order to solve the problem of frequent expressway traffic incidents ,combined with communication tech-nology and GPS positioning technology ,an early warning system based on NFC technology and Android technology is presen-ted for the treatment of expressway traffic incidents .The overall system framework is proposed ,the Android client soft-ware ,early warning device and server-side software are further designed in this paper .In the last ,the functions of the sys-tem are tested .The results indicate that ,the system can quickly and effectively find the timing and location of traffic inci-dents ,and make corresponding treatment to alert and guide subsequent vehicle ,so as to reduce the occurrence of secondary events .
