The Design And Realization Of Wireless System Of Smart Home

Recent years, with the rapid development of science and technology, the wholeworld enters the information age, people’s life arrives at a new stage, meanwhile, thehousing conditions are improved significantly. Nowadays, technicians are able toutilize the technology of information, automation, network, computer intoconstruction and buildings. In the tendency of this development, smart hometechnology rises in response to the proper time and conditions, and it provides thepeople with highly safe, comfortable, real-timed, informationalized, intelligentizedlife spaces. In contemporary society, the high-speed work life rhythm and high-qualityliving environment are essential to people, the smart home technology immediatelysatisfies people’s requirements greatly.The development of smart home system is the inevitable trend of technologyinnovation in our country and the essential choice of housing industry modernization.It is necessary to apply the intelligent building technology to civil architecture.This paper explains the concept of smart home, introduces the currentdevelopment conditions of smart home technology at home and abroad in detail,analyzes development tendency of smart home in our country, researches into theexisting problems in smart home technology, finally, on the technology side, thispaper will provide a solution based on ZigBee wireless communication technology todesign and realize the smart home. ZigBee is a kind of burgeoning technology whichis of low complexity, power saving, low cost, short delay, high capacity, highcommunication efficiency etc., there are many sensors in the family networkenvironment which requires short-range wireless connection, in such a environment,ZigBee technology can be used to realize the efficient communication. Theoutstanding features of ZigBee technology are small-range-transmission andlow-transmission-rate, so it is suitable for Indoor small flow data services.This paper adopts the structure which is based on control system and enclosedby wireless sensor network to construct the whole smart home system, introduces theconstruction pattern, takes serial interface communication and wireless temperature gathering as examples to show the development and realization of sub systems insmart home, this process constructs the reasonable development order for therealization of the whole network. As the one of the most important subsystems ofsmart home system, this paper will also introduce the construction and realization ofvideo intercom system in intelligent building, and through concrete project case,illustrates the definition of interfaces between internal software and externalcomponents, the instruction of function of each module, the details of data structureand the specific realizations.
