Research And Design Of Smart Home Systems Based On ZigBee And ARM11

With the development of embedded system and communications technology,the smart home concept has entered the public eye gradually.In foreign countries smart home has carried out earlier,and there are already relatively mature products available,but it still lacks of uniform industry standards which largely restrict the development of the industry.Traditional domestic appliance manufacturers are starting to enter the market with the wave of smart home,but it still confines to a small minority of high-end consumer groups.This paper presents a smart home system based on wireless sensor network.Along with the" Internet of things" Twelfth Five-Year Plan" development plan" published,the Internet of things as a new generation of information communication technology has become the new growth point of national economy,and its development perspective is very wideThis paper proposes the smart home system based on ZigBee technology,the wireless sensor networks built on ZigBee technology can largely meet the actual demand of excellent comfortability,simple use,good expansibility and effective cost.Design of intelligent control platform based on ARM technology enjoys the small size and the convenient to use which changes the dependence the traditional smart home system of the PC client.This paper exposes and argues the subject deeply from both theoretical and practical aspects,and develops the wireless sensor networks terminals and hardware systems of intelligent control platform.Paper is divided into four parts.The first part introduces the research background and the market situation of the selected topic,and briefs the status of the smart home at home and abroad and the problems existed.The second part is the theoretical study and proposes improvements,and briefly describes the IEEE802.15.4 and ZigBee technology,and analyzes the advantages of building smart home systems based on wireless sensor networks.Through the existing market demand analysis then the paper presents the overall structure of the smart home system,and finally demonstrates all of the system sub-module detailed design specifications.The third part is the core of the paper which completes the core hardware design of wireless sensor networks terminal and intelligent control platform,and verifies the feasibility and reliability of the system by the system test.The fourth part is the conclusion which analyzes and summarizes the smart home system,and makes prospects of the home system development.
