Research And Design Smart Home Gateway Based On S3C6410

As the communication technology, Internet technology and the rapid development ofembedded technology, all kinds of automatic and intelligent products emerge in endlessly,greatly changed people’s way of life, promote the people desire for a higher quality of life. Butthe traditional consumer electronics independent control alone, and no effective centralizedcontrol network, using very inconvenient. So design low cost, low power consumption, simpleand convenient operation, and can arrange time to control the intelligent home gateway systemis necessary.This paper presents a research scheme based on S3C6410embedded intelligent homegateway and technical implementation. From the system hardware and software selection andthe analysis of the internal network, to the construction of the hardware and software platformand development, finally realizes the control of household appliances through semanticanalysis and image sharing related functions such as intelligent home gateway. Semanticanalysis is mainly based on AC algorithm implementation pattern string matching, and thematching results are sent to the serial port data processing module to realize the control ofhousehold electrical appliances; Voice control household appliances mainly adopts MSP20speech recognition platform, system of local voice data can be converted to text information,matching with text information analysis, to determine the effectiveness of the user’s voicecommands, and through the ZigBee network to send home appliance control instruction;Images and video sharing mainly through to obtain video or image file from the server, andthen adopt S3C6410hardware decoder to decode the video and image files, and through theVGA interface display output. System adopts modular design, reduces the coupling of eachfunction module program, to facilitate the realization of the system, debugging andmaintenance.Gateway test show that the gateway to realize the control of household appliances, photosharing effect is good, the image is clear, suitable for application in the smart home system, and the system hardware and software functions in accordance with the user personalizeddemand, easy extension, and system upgrades, and its low cost, easy to promote.
