Research And Implementation Of Smart Home System Based On Multi-mode Data Transmission

With the rapid development of the Internet, advances in technology and the continuous improvement of living standards, people are increasingly pursuing more comfortable environment, convenient and secure high quality of life. With the proposal of the Internet of Things, the concept of smart home is gradually accepted by people, smart home system involves network communication, automation, sensor, electronic, computer, embedded technology, etc. People can use these techniques for intelligent management of home appliances, it is changing the people’s way of life and people’s habits, smart home construction and design will be the trend of social development.This paper analyzed the current situation of the smart home, detailing the relevant technical principles of smart home, knowledge of software and hardware, and this solution took the AT91SAM9261 core gateway as the center, integrated WiFi, Bluetooth, Internet three data transmission modes and mobile can be used instead of many home appliance remote controls: WiFi or Bluetooth mode can be used to control the home appliances and monitor environment in home, you can also switch the Internet mode outside the home, realizing various functions remotely over the Internet; this solution turned a large number of remote controllers into a smart mobile phone control to solve the problems of having too many remote controls in real life, remote controls used for a long to failure, use angle, distance is limited. Besides, bring convenience to the mobility of the population.This paper through the interactive test that between Android phones and PC terminals in WiFi, Bluetooth, Internet and other communication conditions and underlying device nodes at home such as television, Ammeter, Gas meter, Water meter, fluorescent lights, curtains and temperature nodes, indicating this smart home system adapt to different situations, different distances, different environments and have stronger real-time capability, in line with concept of smart home and functional requirements, it is worth spreading and learning solution.
