摘要
为了提高电动汽车运行的安全性,设计并实现了一种基于4G网络的电动汽车远程监测系统。该系统将车载终端采集的电动汽车车辆CAN总线获取的电池、电机和GPS位置信息等数据进行整合,并将数据信息通过车载终端的4G通信模块发送到监控中心,服务器对数据进行存储、分析与处理,远程监控系统可提供用户信息查询、车辆状态信息查询、车辆轨迹查询、电池故障信息报警和汽车故障报警等功能,实现对电动汽车的监控。实验测试结果表明,该系统可实现对电动汽车运行状态的实时监测和故障诊断。
In order to improve the safety of electric vehicle operation,a remote monitoring and service system of electric vehicle based on 4G network is designed and implemented,the system integrated the data of battery and motor obtained by CAN bus,send to monitoring server center through 4G network,server stores,analyzed and received the information,the system provided users with the functions of user info query,vehicle state information query,vehicle track query,battery fault information alarm and car fault alarm,to achieve the monitoring function of electric vehicles.The system was tested,and the designed system can realize real-time monitoring and fault diagnosis of electric vehicle.
