一种车载终端软件架构及实现

车载终端是车联网系统的重要组成部分, 为了提高终端软件的可靠性和开发效率, 参考NGTP(Next Generation Telematics Pattern), 设计了一个开放式的车载终端软件架构. 在该架构中, 系统由移动终端、后台支撑系统、车载终端及后台业务系统组成, 各部分之间通过标准数据协议进行数据交换, 实现车辆远程数据采集和诊断、紧急情况处理、远程查询及控制等车联网典型应用. 为了提高终端软件系统的可靠性, 将终端软件分解成功能系统与守护系统两部分, 通过守护系统实时监控功能系统, 当功能系统出现故障时, 重新启动功能系统来保证终端软件系统的有效性. 根据该架构开发的车载终端验证了方案的有效性.

Vehicle-Mounted Terminal Software Architecture and its Implementation

Vehicle Terminal is an important part of the IOV(Internet of Vehicle). To improve the reliability and development efficiency of the Terminal software architecture, we designed, referring to NGTP (Next Generation Telematics Pattern), an opening software architecture for the vehicle terminal, in which the IOV system consists of several parts, mobile terminal, background support system, vehicle terminal and background process system. Every part of the IOV system exchange data according to the standard data protocol to complete some typical applications of the IOV, such as remote data acquisition and diagnosis, emergency treatment,remote query and control, etc. The terminal software is decomposed into two parts,function system and guardian system, to improve the reliability. Real-time monitored by the guardian system, the function system will be rebooted upon it breaking down. And the feasibility was verified by the vehicle terminal designed according to this architecture.
