摘 要
    鉴于现阶段的多媒体技术中仅仅涉及到图像和声音，而就是游艺机中也只用到人体皮肤的运动感觉，而人体中有五官从媒体的定义上应该还有嗅觉和味觉媒体，本文提出了一个以AP7003语音信号识别系统为核心的小型气味发生控制系统。给出了一个简洁的AP7003的控制电路，分析了输出地址，描述了不同类型的输出电路和输入电路；介绍了从特定构造的气味发生器中获得决定气味发生动作的气味数据的原理；给出了主控制电路图。目前，该系统已在一个小型音乐气味工程中应用，取得了令人满意的效果。
本文主要研究利用语音识别AP7003芯片控制气味发生器的工作原理和工作过程，并用单片机AT89S52对AP7003初始化和控制通讯，而AP7003则将麦克风等传入的语音信号经过识别后控制不同的气味发生器工作情况，以达到使场内气味的变化与音乐或语音所发生时场景的气息一致，加大还原电影或其他音乐艺术的真实场景效果。因此除视听信息传输外再加入嗅觉信息，能更充分完善感官效果，让人达到身临其境的感觉。
而在对当前家用智能电器设备需求情况广泛调查的基础上，结合本工程实际需要，针对计算机超媒体技术的特点，研制开发了基于AP7003－01的语音识别功能的智能控制器,旨在改变视听效果，通过不断的声音和图像的不断变化而改变居住场所气味的变化,从而达到改变室内空气味道的目的,使人有一种身临其境的感觉为目的。如今超媒体引领的气味发生器便可以让他们的梦想变为可能。本系统便是受此启发，其主要目的是用于实现现场气氛的调节，从而达到改变室内环境味道。
在上述硬件电路及控制算法的基础上，利用C语言，研制开发了超媒体气味发生器，控制气味发生器主要由语音控制芯片AP7003-01来实现。

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.
