一种智能车载终端系统设计

Design of an intelligent vehicle-mounted terminal system

现有车载终端只能提供视频服务、网络服务等单一功能,且存在提供的网络服务不能区分不同用户,服务质量不高的问题。设计一种智能车载终端系统,该系统的硬件电路以主控模块为核心,利用大功率的路由模块提供无线网络共享,采用C语言编程实现了上网功能、连接功能、管理功能、查询功能,在无需其他基础设施的情况下即可实现无线网络共享服务、多媒体服务、GPS定位服务以及区分不同用户的功能。测试结果表明,该系统设计合理、使用方便快捷,同时具有功能多样化、无线共享能力强、数据传输速率高、服务质量高的优点。

Since the existing vehicle-mounted terminal can only provide single functions such as video service and network services, and has the problems of the provided network services failing to distinguish different users and low quality of service, an intelligent vehicle-mounted terminal system was designed. In the system, the master control module is taken as the core of hardware circuit, and the high-power routing module is adopted to provide wireless network sharing service. The functions of on- line surfing, connection, managenlent and query were realized by means of C language progralmning. Wireless network sharing service, multinledia service, GPS positioning service and the function of distinguishing different users were realized without re- quiring any other infrastructure. The test results show that this system has a reasonable design and convenient operation, and has the advantages of diversified functions, strong wireless sharing capability, high data transmission rate, and high quality of service （QoS）.
