【摘要】：随着汽车在日常生活中地位的不断提高，人们对汽车所能提供的多媒体娱乐服务也有了更高的要求。21世纪初，由孤立的车载多媒体设备构成的车载信息娱乐系统已经无法满足人们日益增长的需求，因此各种车载多媒体网络应运而生。目前，应用最为广泛的车载多媒体网络技术当属MOST网络技术，它以带宽高，系统结构清晰，，上层应用灵活和使用线束少等优势推动着车载信息娱乐系统的不断发展。本文为了进一步强化MOST网络在多媒体娱乐系统方面的优势，提出了MOST网络和互联网络网关的设计与实现方案，旨在将互联网络中丰富的多媒体数据引入MOST网络中，使整车的多媒体信息娱乐功能进一步提高。首先，从MOST网络和互联网络的协议入手，分析各层协议的相互关系，对比两种网络协议的异同，进而设计通信协议。然后，对该网关的系统结构进行了详细的描述，说明各组成部分的作用以及相互之间的协同关系。其次，论述如何把基于单片机的MOST网络程序移植到嵌入式Linux操作系统上，编写网关通信程序并将通知服务应用于网络拥塞控制。最后实现该网关，为该网关设计可触控的操作界面，并通过实验证明该网关功能的实用性和性能的稳定性。
[Abstract]:With the increasing status of automobile in daily life, people also have higher requirements for the multimedia entertainment service provided by automobile at the beginning of the 21st century. The on-board information entertainment system composed of isolated vehicle multimedia devices has been unable to meet the increasing needs of people, so a variety of vehicle-mounted multimedia networks came into being. At present, the most widely used vehicle multimedia network technology is MOST network technology, which promotes the development of on-board information entertainment system with the advantages of high bandwidth, clear system structure, flexible upper application and less wire harness. In order to further strengthen the advantages of MOST network in multimedia entertainment system, this paper proposes a design and implementation scheme of MOST network and Internet gateway, aiming to introduce rich multimedia data into MOST network. So that the vehicle's multimedia information entertainment function further improved. First of all, starting with the protocols of the MOST network and the Internet, this paper analyzes the relationship between the protocols of each layer, compares the similarities and differences between the two kinds of network protocols, and then designs the communication protocols. Then, the system structure of the gateway is described in detail. Secondly, it discusses how to transplant MOST network program based on MCU to embedded Linux operating system, write gateway communication program and apply notification service to network congestion control. Finally, the gateway is implemented, and a touch-controllable interface is designed for the gateway. The practicability and stability of the gateway are proved by experiments.
