【正文】 鍵 詞 ： 云 技 術(shù) ； 單 片 機 ； 智 能 家 居 ； 語 音 控 制 II Abstract In recent years, with the improvement of technology development and standard of living, people on the home environment proposed higher requirements, the concept of smart home system began to the public, although the development is slow, but smart home is certainly in the future for a long time a intelligent control field of the hot topic. Speech is the most natural way of interaction, the use of speech recognition and control technology to realize the control of household appliances is an important part of the intelligent Home Furnishing. The rise of cloud technology has bee the most important applications of speech recognition. Because of the low power consumption, low cost, easy operation and easy installation of the smart home, a lot of parative study and actual parameter analysis are used in this paper. By using the device, the user can remotely control the home appliances by any two tone multi frequency telephone (including a fixed telephone and a mobile telephone), and a smart home system is built to realize the voice control of the household electric appliance. This paper designed a appliances telephone remote control system based on AT89 C51, basic principle of AT89C51 on the number of rings were counted, when reaching the set number of rings AT89C51 control automatic telephone off hook, and controls the voice prompt circuit beep, requires that the input system startup password, and then check the password, when to enter the correct password, the voice prompt circuit prompted to enter the home appliances control code dialed number by the DTMF decoding circuit decoding and sent to AT89C51 decoding, so as to control household appliances[1].
