摘　　要：为了提升车辆管理系统的应用效果及用户满意度,设计一种基于Hadoop的车辆管理系统.该系统是以Hadoop为核心的三层架构,数据存储层利用数据采集接口接收交警侧采集终端传输的车辆数据,经数据加载、查询、存储后,通过数据访问服务接口将数据传输至服务层.服务层利用Min-Max方法获取车辆移动近似节点和车辆短时位置信息,获取最终的车辆节点定位结果,可实现车辆历史信息查看和预警信息发送,同时将逻辑处理结果经服务通信接口传输至显示层显示.实验结果表明,该系统的吞吐量较高,可允许大批量用户同时访问;车辆定位结果的均方根误差较低,定位较为精确;系统执行时间低,可快速响应用户需求,且用户满意度较高.In order to improve the application effect and user satisfaction of vehicle management system,a vehicle management system based on Hadoop is designed.The system is a three-tier architecture with Hadoop as the core.The data storage layer uses the data acquisition interface to receive the vehicle data transmitted by the traffic police collection terminal.After data loading,query and storage,the data is transmitted to the service layer through the data access service interface.The Min-Max method is used in the service layer to obtain the approximate moving node and short-term position information of the vehicle,and obtain the final positioning result of the vehicle node,which can realize the view of vehicle history information and the transmission of early warning information.At the same time,the logic processing result is transmitted to the display layer for display through the service communication interface.The experimental results show that the throughput of the system is high,allowing a large number of users to visit at the same time;the root mean square error of vehicle positioning results is low,and positioning is more accurate;the system execution time is low,which can quickly respond to the user needs,and the user satisfaction is high.
