【摘要】:近年來(lái),隨著社會(huì)科學(xué)技術(shù)的不斷進(jìn)步和人民大眾生活水平的不斷提高,城市交通發(fā)展越來(lái)越快,人們對(duì)于車內(nèi)的娛樂、安全等方面的需求也日益增多,因而,對(duì)多媒體終端設(shè)備的要求也就越來(lái)越高,能夠完成的功能也越來(lái)越廣,物聯(lián)網(wǎng)這一概念也在不斷的被完善。物聯(lián)網(wǎng)的各類子網(wǎng)絡(luò),尤其是車聯(lián)網(wǎng)的應(yīng)用范圍也越來(lái)越廣。由此,對(duì)車聯(lián)網(wǎng)的關(guān)注和發(fā)展應(yīng)運(yùn)而生。本文正是在這一背景下,依照車聯(lián)網(wǎng)所應(yīng)能提供的功能,基于新一代的高性能嵌入式平臺(tái)、功能完善的嵌入式操作系統(tǒng)、高速便捷的新興通信技術(shù),研究、設(shè)計(jì)與實(shí)現(xiàn)一款能結(jié)合以上各領(lǐng)域最新研究成果的,高性能車載流媒體音頻系統(tǒng)。并重點(diǎn)對(duì)其服務(wù)器端進(jìn)行討論。本文對(duì)整個(gè)課題的背景情況做了介紹與分析,包括了物聯(lián)網(wǎng)車聯(lián)網(wǎng)近年來(lái)的發(fā)展?fàn)顩r及國(guó)內(nèi)外的研究與發(fā)展現(xiàn)狀等。對(duì)于實(shí)現(xiàn)系統(tǒng)的傳輸模式進(jìn)行了選擇,并分析了服務(wù)器端包含的各項(xiàng)關(guān)鍵技術(shù)點(diǎn)。本文設(shè)計(jì)的服務(wù)器端從功能上分為四個(gè)模塊,網(wǎng)絡(luò)連接、客戶端需求響應(yīng)、并發(fā)編程的實(shí)現(xiàn)以及數(shù)據(jù)庫(kù)調(diào)用。從相關(guān)技術(shù)角度,網(wǎng)絡(luò)連接通過(guò)套接字實(shí)現(xiàn),客戶端需求響應(yīng)通過(guò)文件傳輸實(shí)現(xiàn),并發(fā)編程選用了多線程技術(shù),而數(shù)據(jù)庫(kù)選用了My SQL數(shù)據(jù)庫(kù)。工作流程上,首先車輛上的車載客戶端與服務(wù)器實(shí)現(xiàn)網(wǎng)絡(luò)連接,然后以文件傳輸為基本形式,通過(guò)數(shù)據(jù)庫(kù)進(jìn)行信息控制來(lái)完成各項(xiàng)客戶端功能的實(shí)現(xiàn),并通過(guò)并發(fā)編程保證服務(wù)器端能夠同時(shí)對(duì)多臺(tái)客戶端進(jìn)行響應(yīng);谒O(shè)計(jì)的服務(wù)器端架構(gòu)的方案,本文完成了對(duì)整體架構(gòu)的實(shí)現(xiàn),并重點(diǎn)討論了其中的幾項(xiàng)主要技術(shù),如多線程編程、My SQL數(shù)據(jù)庫(kù)的調(diào)用等。并分析了本次研究所完成的架構(gòu)中不足的地方,為下一步工作的重點(diǎn)和改進(jìn)方案提出了一個(gè)參考建議。
[Abstract]:In recent years, with the continuous progress of social science and technology and the continuous improvement of people's living standards, urban traffic is developing more and more rapidly, and the demand for entertainment and safety in cars is increasing day by day. The requirement of multimedia terminal equipment is more and more high, the function that can be completed is more and more extensive, the concept of Internet of things is also being perfected continuously. All kinds of subnetworks of Internet of things, especially the application scope of the network of cars are more and more extensive. Under this background, according to the function that the vehicle networking should provide, this paper is based on the new generation of high-performance embedded platform and the perfect embedded operating system. High-speed and convenient new communication technology, research, design and implementation can be combined with the latest research results in the above fields, In this paper, the background of the whole subject is introduced and analyzed. Including the development of the Internet of things in recent years and the research and development status at home and abroad. The transmission mode of the system is selected. In this paper, the server is divided into four modules, network connection, client demand response, concurrent programming and database call. The network connection is realized by socket, the client's demand response is realized by file transmission, the multithreading technology is used in concurrent programming, and my SQL database is used in the database. First of all, the vehicle-mounted client on the vehicle realizes the network connection with the server, then takes the file transfer as the basic form, through the database carries on the information control to complete each client function realization, And through concurrent programming to ensure that the server can respond to multiple clients at the same time. Based on the design of the server-side architecture, this paper completes the implementation of the overall architecture, and focuses on the discussion of some of the main technologies. For example, multi-thread programming is used to call my SQL database, and the deficiencies in the architecture of this research are analyzed, and a reference proposal for further work and improvement scheme is put forward.
