Research And Application Of Smart Home Systems Based On Wireless Sensor Network

Smart home is the utilization of advanced integrated wiring, computer, Internet, automatic technology, integrating family hardware and software infrastructures to combine the family smart controlling and information exchanges, achieve the perception of family environment information and intelligent control of household facilities, provide home users with intelligent family life services and build safety, convenience, intelligent home environment. Internet of Things is the important infrastructure of smart home which is used to get status data of environment, devices and users. But the core of smart home technology is intelligence which can provide accurate, personalized, intelligent active service through the analysis of environmental data. It is the key to smart home technology.Some large enterprises have been carried out related research of smart home, and there are already some good products available, but these products and technologies are usually designed for a certain aspect and their eyes are not on the whole family environment. Because of these there are not mature commercial systems in the smart home services. This article put eyes on the family’s perspective, presented a multi-scene recognition based on SVM model home environment through real-time data analysis, processing, so that the higher layer of the system can take different strategies for different scenarios.This paper first introduced the background of the subject and the purpose and significance of research topics, after the analysis of the current smart home technology, the paper identified the main research directions. First, it summarized the key technologies which are need in the smart home system including wireless sensor technology and data fusion technology. Secondly, after the introduction of the key technologies it abstracted our common household scenes and presented it by mathematical model, based on this a SVM-based multi-scene recognition model was provided. At last a smart home service system was designed and developed.
