Research And Implementation Of Intelligent Home Control System Based On Cloud Platform

With the improvement of people’s living standard, the requirements of intelligent control of home appliances are also increased. Currently, when using the smart home system, people can control the home appliances through the gateway in the house. But remote control can not be achieved and the information of the home appliances can not be query through the Internet. Though users can control home appliances via their mobile phone, a variety of software need be installed to their mobile phone. The burden on the mobile phone can be increased.To cope with these problems, a control system of smart home based on the cloud platform is designed. The thesis focuses on the design of the cloud platform and the home gateway. MySQL database is established to realize the function of storing control information on the cloud platform. The code is written using PHP language to realize the communication through the cloud platform, WeChat and the home gateway. The code is deployed on the cloud platform. The home gateway consists of two parts: network communication module and ZigBee communication module. The home gateway is based on the Arduino platform. The W5100 module can support TCP/IP protocol stack and it can be used to access to the Internet. The HTTP protocol is used to write the code to access to the cloud platform. RL78/I1A is used as the main control chip to build the ZigBee communication module. The touch screen is designed to control the system. The network of wireless communication is realized by the DRF1607H module produced by DTK company. The circuit of ZigBee communication module is designed and the PCB board is made. The code is written to realize the function of adjusting the brightness and color of the ceiling lamp by PWM wave.After testing and debugging, the function of the control system is verified by using the ceiling lamp. WeChat can be used to realize remote control and the control information can be find through the cloud platform. The whole system can work stably.
