Design And Implementation Of Internet Of Things Prototype System For Smart Home

The rapid development of science and technology led to social progress andimprove people’s living standards, people have become increasingly demanding oftheir own home environment. As people increasingly in-depth research on smarthome, smart home products are becoming increasingly numerous, and allow people togradually experience the advantages of smart home. Especially in the situation of the"Internet of Things" has become a worldwide study boom, smart home as the"Internet of Things" application direction to people’s living environment will bringnew opportunities and challenges.This article abandoned the traditional design concept of smart home system,proposed a new type of smart home prototype system based on three technicalarchitecture of the Internet of Things. The operation of the system does not requirethe user too much manual intervention, user only need some simple system settings,the system can be based on user settings autonomous operation, to achieve themonitoring of the user home state of the environment and the electrical equipmentworking condition.This paper mainly completed the following work:（1）Based on Internet of things three layer model of the technical architectureof the prototype system, designed system framework, analyzed the overall designscheme and functions of the prototype system.（2）Constructed ZigBee wireless network based on ZigBee protocol stack of TIcompany under the IAR development environment and developed application.（3）Combined with CC2430chips, the specific features of ZigBee node areanalyzed in the hardware design and working process.（4）Under Microsoft.NET platform，based on ASP.NET and ADO.NETtechnology of smart home system, the web site and the system business processingcenter were designed.（5）Based on Microsoft SQL Server2008, the database Server of intelligenthousehold system is designed.（6）The function design of the intelligent home gateway and hardwareselection.（7）The prototype system has realized, and finished the system performancetest and function test. The final experimental results show that the prototype system does not requiretoo much involvement, based on user preferences, autonomy, security and stability, toachieve a higher degree of intelligence. The model system could meet the multi-useruse, as soon as it has many advantages, such as easy to maintain and upgrade,resource conservation, low-cost、safe, efficient and strong portability, so this modelhas great application prospects.
