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.
