基于WebSocket的车辆GPS信息实时推送系统的实现

Implementation for system of real-time pushing vehicle's GPS information based on WebSocket

文中针对车辆管理系统中如何实时获取车辆定位信息问题,采用缓存数据库实现对终端实时反馈的GPS信息进行存储,推送服务器利用Websocket将缓存数据库中数据的变动情况进行处理并将处理结果推送至Web应用,从而实现车辆GPS信息在地图上进行图形展示,并进行实时追踪。当然利用该系统也能实现实时报警信息的推送,从而实现监控人员的对此类情况的及时处理,从而避免产生严重的灾难及后果。

In order to solve the problem that how to get vehicle ＇s GPS information in vehicle management system in real-time,this paper use cache database to save the Real-time GPS information from the interactive terminal server; and then the pushing service pushes the newest GPS information to Web application client. The client utilizes the GPS information to mark the vehicle on the map or show on the datagrid, monitors the vehicle in Real-time. Of course, we can also take use of this system to push the alarming information to handle some emergencies in Real-time. In this way, some more serious disasters will be avoided.
