Design And Implementation Of Smart Home Remote Control System

With the development of social economy and Information technology,people's demand of comfort,intelligence and security is higher and higher,more and more researchers and even enterprises began to develop intelligent household products.The study of smart home products is of importance in theory and of value in practice.This paper on the basis of analyzing the present situation and trend of development of the smart home at home and abroad,the integration of application server and XMPP server and combined the technology of wireless sensor network,design and implements a complete set of smart home remote control system.The system consists of hardware system,communication system and software system.In the aspect of hardware system,the paper constructed a wireless sensor network and realized intelligent gateway based on ARM microcontroller and Zig Bee coordinator.Using the CC2530 core module to designed the function node of the coordinator,device control terminal nodes and the environmental data acquisition terminal nodes.And in the device control terminal nodes achieved the intelligent curtain,brightness adjustable lighting,intelligent air conditioning,background music,intelligent socket and so on.In the aspect of communication system,this paper combines the XMPP protocol,Http protocol and Zig Bee protocol and implements a complete communication system.In the home network,this paper uses the Zig Bee technology as the communication technology of family sensor network.Based on the research of access control mechanism of wireless sensor network node,this paper uses the Z-Stack protocol stack to achieve the wireless sensor network.In the wide area network,this paper uses the XMPP server combined with the application server to realize the remote control server,which the XMPP server implementation uses the open-source Open Fire server,and the application server implementation uses the open-source tomcat server.In the aspect of client,this paper designed and implemented user control terminal and home control center which called smart gateway.They are all based on Android.Smart gateway as a home LAN and WAN connection point and the center of the message transformation,it plays a very important role in the smart home remote control system.Finally,the design and implementation of the system was tested by this paper,and verified the corresponding functions of the system.
