【摘要】：隨著汽車在日常生活中地位的不斷提高，人們對(duì)汽車所能提供的多媒體娛樂服務(wù)也有了更高的要求。21世紀(jì)初，由孤立的車載多媒體設(shè)備構(gòu)成的車載信息娛樂系統(tǒng)已經(jīng)無法滿足人們?nèi)找嬖鲩L的需求，因此各種車載多媒體網(wǎng)絡(luò)應(yīng)運(yùn)而生。目前，應(yīng)用最為廣泛的車載多媒體網(wǎng)絡(luò)技術(shù)當(dāng)屬M(fèi)OST網(wǎng)絡(luò)技術(shù)，它以帶寬高，系統(tǒng)結(jié)構(gòu)清晰，，上層應(yīng)用靈活和使用線束少等優(yōu)勢推動(dòng)著車載信息娛樂系統(tǒng)的不斷發(fā)展。本文為了進(jìn)一步強(qiáng)化MOST網(wǎng)絡(luò)在多媒體娛樂系統(tǒng)方面的優(yōu)勢，提出了MOST網(wǎng)絡(luò)和互聯(lián)網(wǎng)絡(luò)網(wǎng)關(guān)的設(shè)計(jì)與實(shí)現(xiàn)方案，旨在將互聯(lián)網(wǎng)絡(luò)中豐富的多媒體數(shù)據(jù)引入MOST網(wǎng)絡(luò)中，使整車的多媒體信息娛樂功能進(jìn)一步提高。首先，從MOST網(wǎng)絡(luò)和互聯(lián)網(wǎng)絡(luò)的協(xié)議入手，分析各層協(xié)議的相互關(guān)系，對(duì)比兩種網(wǎng)絡(luò)協(xié)議的異同，進(jìn)而設(shè)計(jì)通信協(xié)議。然后，對(duì)該網(wǎng)關(guān)的系統(tǒng)結(jié)構(gòu)進(jìn)行了詳細(xì)的描述，說明各組成部分的作用以及相互之間的協(xié)同關(guān)系。其次，論述如何把基于單片機(jī)的MOST網(wǎng)絡(luò)程序移植到嵌入式Linux操作系統(tǒng)上，編寫網(wǎng)關(guān)通信程序并將通知服務(wù)應(yīng)用于網(wǎng)絡(luò)擁塞控制。最后實(shí)現(xiàn)該網(wǎng)關(guān)，為該網(wǎng)關(guān)設(shè)計(jì)可觸控的操作界面，并通過實(shí)驗(yàn)證明該網(wǎng)關(guān)功能的實(shí)用性和性能的穩(wěn)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.
