| With the development of communicational and microelectronics technology,people’s material life is becoming richer and better, under this craze,the requirementsof life quality is also rising. As a new concept of life,smart-home is born in such aupsurge. It has been got rapid development in recent years, and will become theinevitable trend of future residential development at the same time. Although themarket of smart-home in China is become more popular, it has not really enteredpeople’s daily life until now. The reason is there are some usability issues on the priceand performance. Users eager to have a high efficiency, low cost, reliable, functional,user-friendly control system, but it is obviously contradicted to the current situation.This paper studies the key technologies of Smart-home system, referencing theresearch results at domestic and abroad. So under the premise of existing technology Icame up with the idea of the design under the precondition of the prior technology:Smart-home integrated control platform which is respectively described the design ofthis paper form application layer, perception layer, and device layer. Integration thatshowed by application layer, is specific forms of implementation with perception layerand device layer. Users manage the system by data receive, and control the system bydata transmission.Application Layer: This layer is the actual operation and user’s interacted layer.Through operating this layer users can control and manage the system. In this layer,introduce the popular technology:virtual reality, and use the software which isUnity3D to establish3D model, through the code realizing roaming in the model.Then after coding in encapsulation it can be used in the mobile device,such asAndroid, to allow other users to roaming scenarios by pad or cell phone.Perception Layer: This level is primarily responsible for the perception of theenvironmental information of home, and converts the information into correspondingelectrical signals through device level, then transmits those perceptions of the environmental information to application layer to show to users. With the continuousimprovement of living standards, the range of the equipments of Smart-home arebecoming wider and wider. With the range of intelligent of household equipmentincreasingly wide, more and more devices added to the smart-home network, usingtoo many devices are transmission data by only one way, once a core part of thenetwork,such as coordinator, appears fails, the entire network will be paralyzed, sothat the reliability of the intelligent home network is greatly reduced. This paper isoptimized for this innovation, through the study of transmission technology featuresand characteristics of wireless data, and analysis the information of environmental,introduction of Bluetooth technology for wireless data transmission.Device Layer: This layer is the most cutting-edge part to achieve the functions ofthe system and the carrier of specific functions. The sensor, the coordinator, andcontrol module is designed by modularization which enhances the portability of thesystem.At last, testing this design by the system prove that the designed systemaccomplish the design goals which is a stable, low cost, user-friendly system. Becauseof various reasons, there have some shortcomings which are continued to be refinedand improved in future studies. |
