Design And Implementation Of Smart Home System Based On Cloud

Smart home entered the Chinese market more than a decade ago, all kinds of related intelligent household products gradually come to the sight of people. But the current development of smart home technology stage far failed to meet the requirements of people to intelligent household life and comfort, the problems mainly displays in: the lack of industry standards,expensive intelligent equipment, household system is difficult to maintenance, safe hidden trouble, data bottlenecks and low resource utilization.After the study of cloud computing technology, this paper fully discusses the characteristics of cloud computing, presents an intelligent household solutions, the scheme is based on cloud computing, by taking advantage of cloud computing technology to realize the basic function of smart home, and ultimately cloud related technology is successful integrated into the intelligent household. Smart home based on cloud computing of this kind of structure can overcome some of the problems they face. First of all,it is different from the smart home system in the past time which was based on a family server, the existence of the home server makes the smart home system flexibility and maintainability, the user experience is not good enough; Combined with cloud computing can put smart home system in the cloud service, users only need to use a small family gateway to enjoy a comprehensive household services, and users don’t need to worry about complex maintenance of the system. Second, make the use of smart home system cost reduction, the cost of home gateway is relatively low, and the gateway to the sensor nodes within the family and smart device node through the zigbee protocol network, and then collect the node’s perception and forward control commands from the user. In addition, under the environment of cloud computing, thousands of sensory information is stored.Through the study of the large data mining of sensory data, it is advantageous to the smart home system feedback adjustment, and thus provide people with better intelligence services.In this paper, by using the cloud service as the center we implement a smart home system, and implementation of the smart home website and mobile terminal control applications, web sites and mobile terminal through the cloud service system to control the gateway, allows the user to remotely control the current security situation in domestic intelligent device and access to family. In addition, in order to improve storage resource utilization on perception data backup in the cloud,this article analyses the characteristics of intelligent household sensory data and gives the sensory data preprocessing methods, greatly reduce the redundancy of data, at the same time, through the research of data compression storage technology, this article combines intelligent household environment perception data of the characteristics of big time and spatial correlation of several compression algorithms are analyzed, finally choose the LZW compression algorithm based on dictionary and the corresponding optimization, to the compression of the sensor data processing, and gained anticipative effect.
