摘 要
    鑒于現(xiàn)階段的多媒體技術(shù)中僅僅涉及到圖像和聲音，而就是游藝機(jī)中也只用到人體皮膚的運(yùn)動(dòng)感覺，而人體中有五官?gòu)拿襟w的定義上應(yīng)該還有嗅覺和味覺媒體，本文提出了一個(gè)以AP7003語(yǔ)音信號(hào)識(shí)別系統(tǒng)為核心的小型氣味發(fā)生控制系統(tǒng)。給出了一個(gè)簡(jiǎn)潔的AP7003的控制電路，分析了輸出地址，描述了不同類型的輸出電路和輸入電路；介紹了從特定構(gòu)造的氣味發(fā)生器中獲得決定氣味發(fā)生動(dòng)作的氣味數(shù)據(jù)的原理；給出了主控制電路圖。目前，該系統(tǒng)已在一個(gè)小型音樂氣味工程中應(yīng)用，取得了令人滿意的效果。
本文主要研究利用語(yǔ)音識(shí)別AP7003芯片控制氣味發(fā)生器的工作原理和工作過程，并用單片機(jī)AT89S52對(duì)AP7003初始化和控制通訊，而AP7003則將麥克風(fēng)等傳入的語(yǔ)音信號(hào)經(jīng)過識(shí)別后控制不同的氣味發(fā)生器工作情況，以達(dá)到使場(chǎng)內(nèi)氣味的變化與音樂或語(yǔ)音所發(fā)生時(shí)場(chǎng)景的氣息一致，加大還原電影或其他音樂藝術(shù)的真實(shí)場(chǎng)景效果。因此除視聽信息傳輸外再加入嗅覺信息，能更充分完善感官效果，讓人達(dá)到身臨其境的感覺。
而在對(duì)當(dāng)前家用智能電器設(shè)備需求情況廣泛調(diào)查的基礎(chǔ)上，結(jié)合本工程實(shí)際需要，針對(duì)計(jì)算機(jī)超媒體技術(shù)的特點(diǎn)，研制開發(fā)了基于AP7003－01的語(yǔ)音識(shí)別功能的智能控制器,旨在改變視聽效果，通過不斷的聲音和圖像的不斷變化而改變居住場(chǎng)所氣味的變化,從而達(dá)到改變室內(nèi)空氣味道的目的,使人有一種身臨其境的感覺為目的。如今超媒體引領(lǐng)的氣味發(fā)生器便可以讓他們的夢(mèng)想變?yōu)榭赡堋１鞠到y(tǒng)便是受此啟發(fā)，其主要目的是用于實(shí)現(xiàn)現(xiàn)場(chǎng)氣氛的調(diào)節(jié)，從而達(dá)到改變室內(nèi)環(huán)境味道。
在上述硬件電路及控制算法的基礎(chǔ)上，利用C語(yǔ)言，研制開發(fā)了超媒體氣味發(fā)生器，控制氣味發(fā)生器主要由語(yǔ)音控制芯片AP7003-01來(lái)實(shí)現(xiàn)。

ABSTRACT
In view of the fact that in the present stage multimedia technologymerely involves to the picture and the sound, but is in the recreationmachine also only uses the human body skin the kinesthesis, but in thehuman body had the five senses to be supposed also to have the senseof smell delicious sense media from the media definition, this articleproposed had the control system take the AP7003 pronunciation signalidentification system as the core small smell. Has produced a succinctAP7003 control circuit, has analyzed the output address, described thedifferent type output circuit and the input circuit; Introducedobtains the decision smell from in the specific structure smellgenerator to have the movement smell data principle; Has produced themaster control circuit diagram. At present, this system has applied ina small music smell project, has obtained the satisfying effect.
This article main research use speech recognition AP7003 chip controlsmell generator principle of work and work process, and withmonolithic integrated circuit AT89S52 to AP7003 initialization andcontrol communication, but AP7003 then and so on spreads to themicrophone the pronunciation signal controls the different smellgenerator working condition after the recognition, achieved causes inthe field the smell change occurs with the music or the pronunciationwhen the scene breath to be consistent, enlarges the return tooriginal state movie or other music art real scene effects. Thereforejoins the sense of smell information again besides the seeing andhearing intelligence transmission, can the fuller perfect sense organeffect, let the person achieve experiences personally feeling.
But in to the current home use intelligent electric applianceequipment demand situation widespread investigation foundation in,unifies this project actual need, in view of the computer ultra mediatechnology characteristic, the development has developed based on theAP7003 - 01 speech recognition function intelligent controller, is forthe purpose of changing the seeing and hearing effect, changes thehousing place smell through the unceasing sound and the pictureunceasing change the change, thus achieved in the change room the airflavor goal, enable the person to have the feeling which one kindexperiences personally is a goal. Now the ultra media eagerlyanticipates the smell generator then may let their dream possiblybecome. This system then is this inspiration, its main goal is uses into realize the scene atmosphere adjustment, thus achieves the changeindoor environment flavor.
This design has used Protel DXP circuit design software, has carriedon the detailed design to the intelligent controller electric circuitschematic diagram, and has realized the circuit diagram and theelectric circuit board chart transformation through this software.
In the above hardware electric circuit and in the control algorithmfoundation, used the C language, the development develops the ultramedia smell generator, the control smell generator mainly has realizedby pronunciation control chip AP7003-01.
