【摘要】:隨著改革開(kāi)放的不斷地深入,會(huì)展業(yè)蓬勃發(fā)展起來(lái),從展覽的環(huán)境、設(shè)施、規(guī)模、影響等來(lái)看,我國(guó)已經(jīng)成為亞洲的會(huì)展大國(guó),會(huì)展活動(dòng)成為服務(wù)行業(yè)中一個(gè)新的亮點(diǎn),甚至成為一些城市的支柱產(chǎn)業(yè)和帶動(dòng)地區(qū)經(jīng)濟(jì)發(fā)展的新經(jīng)濟(jì)增長(zhǎng)點(diǎn)。為了各參展人員在大型展覽會(huì)上更好的交流,以及能及時(shí)有效的了解各展區(qū)展品的相關(guān)資料,需要良好的語(yǔ)音播放系統(tǒng)。目前MP3播放器因其播放音質(zhì)好、可靠性高、操作便捷等特點(diǎn),也開(kāi)始應(yīng)用在會(huì)展播音系統(tǒng)中。普通的MP3播放器存儲(chǔ)介質(zhì)單一、容量小、功能單一,需要進(jìn)行專門的設(shè)計(jì)方能滿足會(huì)展播音系統(tǒng)的要求。因此根據(jù)目前音頻技術(shù)的發(fā)展和大型展覽會(huì)對(duì)語(yǔ)音播放的需求,大型展覽會(huì)智能MP3播放系統(tǒng)應(yīng)具有很大的靈活、通用性和實(shí)用性。 基于此目的,本文設(shè)計(jì)了一款基于GPL162003A處理器,內(nèi)嵌有操作系統(tǒng)的智能MP3播放系統(tǒng),該系統(tǒng)的設(shè)計(jì)提供了USB接口、SD卡接口,可以連接不同的存儲(chǔ)設(shè)備,突破了容量的限制;能提供便捷化下載語(yǔ)音,高質(zhì)量播報(bào)語(yǔ)音;具有上位機(jī)配置系統(tǒng),能對(duì)聯(lián)動(dòng)設(shè)備進(jìn)行控制,以達(dá)到更好地組織展覽會(huì)工作的目的。 本文首先介紹了大型展覽會(huì)智能MP3播放系統(tǒng)的特點(diǎn),詳細(xì)分析了系統(tǒng)的功能需求和要達(dá)到的性能指標(biāo),在此基礎(chǔ)上給出了系統(tǒng)的總統(tǒng)設(shè)計(jì)方案。本文全面論述了大型展覽會(huì)智能MP3播放系統(tǒng)的硬件設(shè)計(jì)與實(shí)現(xiàn),給出了系統(tǒng)硬件結(jié)構(gòu)圖,對(duì)各個(gè)子模塊:GPL162003A基本電路、存儲(chǔ)器電路、音頻播放電路、實(shí)時(shí)時(shí)鐘和GPS校時(shí)電路、聯(lián)動(dòng)設(shè)備控制電路、電源電路等進(jìn)行了詳細(xì)設(shè)計(jì);本文還說(shuō)明了μC/OS-II在GPL162003A上的移植過(guò)程,詳述了智能MP3播放系統(tǒng)軟件設(shè)計(jì),主要涉及MP3解碼播放模塊、鍵盤(pán)模塊、液晶顯示模塊、USB通訊模塊、SD卡通訊模塊、時(shí)鐘校時(shí)模塊、紅外遙控模塊的軟件編程思路、流程及部分程序。 本項(xiàng)目在完成軟硬設(shè)計(jì)的基礎(chǔ)上,進(jìn)行了樣機(jī)的制作,以及一系列的測(cè)試和相應(yīng)的分析,經(jīng)調(diào)試實(shí)驗(yàn)說(shuō)明所設(shè)計(jì)的大型展覽會(huì)智能MP3播放系統(tǒng)的各項(xiàng)功能能滿足設(shè)計(jì)要求,可達(dá)到預(yù)期設(shè)計(jì)目標(biāo)。
[Abstract]:With the continuous deepening of reform and opening up, the convention and exhibition industry has flourished. Judging from the environment, facilities, scale and impact of the exhibition, China has become a big exhibition country in Asia, and exhibition activities have become a new bright spot in the service industry. Even become the pillar industry of some cities and drive the new economic growth point of regional economic development. In order for the exhibitors to communicate better at large exhibitions and to be able to understand the relevant materials of exhibits in a timely and effective manner, a sound voice broadcasting system is needed. At present, MP3 player has been used in the exhibition broadcasting system because of its good sound quality, high reliability, convenient operation and so on. The ordinary MP3 player has a single storage medium, small capacity and a single function, so it needs a special design to meet the requirements of the exhibition broadcasting system. Therefore, according to the development of audio technology and the demand of voice playing in large-scale exhibition, the intelligent MP3 playing system of large-scale exhibition should be flexible, versatile and practical. For this purpose, this paper designs an intelligent MP3 playback system based on GPL162003A processor with embedded operating system. The design of the system provides USB interface and SD card interface, which can connect different storage devices and break through the limit of capacity. It can provide convenience to download voice and broadcast voice of high quality, and has the upper computer configuration system, which can control the linkage equipment in order to better organize the exhibition work. This paper first introduces the characteristics of the intelligent MP3 playing system of the large-scale exhibition, and analyzes in detail the functional requirements and performance indexes of the system. On the basis of this, the president design scheme of the system is given. In this paper, the hardware design and implementation of the intelligent MP3 playing system for large-scale exhibition are discussed, and the hardware structure diagram of the system is given. For each sub-module: the basic circuit of GPL162003A, the circuit of memory, the circuit of audio playback, the real time clock and the circuit of GPS timing. The control circuit and power circuit of the linkage equipment are designed in detail. This paper also describes the transplant process of 渭 C/OS-II on GPL162003A, and describes the software design of intelligent MP3 playback system, including MP3 decoding module, keyboard module, LCD module, USB communication module, SD card communication module. Clock timing module, infrared remote control module software programming ideas, flow and part of the program. On the basis of the soft and hard design, the prototype is made, and a series of tests and corresponding analysis are carried out. The debugging experiment shows that the functions of the intelligent MP3 playback system designed for the large-scale exhibition can meet the design requirements. Can achieve the expected design objectives.
