开放式车辆远程控制架构研究及应用

Research and Application of Vehicle Remote Control with Open System Architecture

摘要:

为了解决远程控制系统客户端设备类型受限,系统架构不开放及协议不标准问题,实现资源共享,参考NGTP(Next Generation Telematics Pattern),设计了一个车辆远程控制系统架构,并对数据通信协议进行制定;在本系统中,用户通过浏览器登入WebServer,不必开发客户端软件,解决了客户端设备类型受限制问题,提高了系统可维护性;同时为了安全考虑,移动终端不允许直接控制车载终端,设计了后台服务器,用来存储车辆运行状况信息以及转发相应指令;系统中数据通信协议是在NGTP消息协议的基础上进行制定,统一了消息格式,便于管理。运用远程查询和远程控制对系统进行验证,查询的响应时间在3s左右,控制的响应时间在2s之内,均在允许的范围之内,结果证明了系统的可行性。

Abstract:

To achieve resource sharing, a vehicle remote control architecture refer to NGTP(Next Generation Telematics Pattern) is designed to solve the problems that device types of client in remote control system are limited and system architecture is not open and the protocol is not standard, and the data communication protocol is work out. In the system, without developing client software, the user logins to the WebServer through the browser solving the problem that client type is limited, improving the system maintainability. For the sake of safety, the mobile terminal is not allowed to directly control the vehicle terminal and the backend server is designed to save vehicle running status information and transmit some orders. To unify the message format , the data communication protocol in the system is draw up based on NGTP Message Protocol for easily managing. Remote inquire and Remote control are used to verify the system and the result proves the feasibility of the system.
