Abstract The development of science and technology promotes people’s living standard is getting better, as well as people’s concept of life is constantly advanced。 With the development of communication and technology, people also have higher levels of requirements on the home environment, to promote the continuous development of smart home, which integrates the automatic control technology and network communication technology。 This thesis focuses on the design of data acquisition terminal of smart home control system。

First of all, this thesis describes the research background of smart home system, and summarizes the development and research status of smart home system and relevant key technologies。 Secondly, after researching and comparing, I ascertain the Operating System of the control terminal is based on Android Operation System and the technical solution of network communication for the smart home system chooses WIFI technology。 And then, the overall structure of the system is designed according to the characteristics of smart home。 The smart home control system is pided into two parts: the Android monitoring platform and the data acquisition terminal。 And the text is focus on the latter, to realize the home control via AT89C51  SCM,  including the lighting control system,to test indoor light intensity and control lighting switches automatic or manual; the infrared induction alarm system, through the infrared induction, the security of the specific location is detected and the alarm is given; the temperature and humidity monitoring system, to detect the indoor real time temperature and humidity values and and the overrun alarm and automatic control of the air conditioning switch are carried out; the smoke and combustible gas alarm system, to detect the content of specific gas in the room, and carry out the danger alarm。

Finally, the design of the software part of the program written using C language, and the simulation debugging using Proteus software。 The  system performs well in the simulation stage, and shows that the system has good stability and reliability。
