| With the rapid development of computer technology, communication technology and sensor technology, smart home system enters people’s daily life from concept to reality. With the organic combination of a variety of electrical appliances, smart home system aims to realize intelligent management and provide a comfortable, low-carbon living environment for people.Smart home system consists of wireless sensor-actuator networks, gateways and application management modules. Wireless sensor-actuator networks act as a strong link between the information world and the physical world, whose wireless sensor is composed of sensing and controlling nodes. The target of the application management module is to manage and control these nodes to achieve data acquisition and equipment control, and to provide users with the ability to display based on the location and a set of rules to support integrated services. Smart home system is based on publish/subscribe model, nodes publish their own service capabilities, and users subscribe to the appropriate service capabilities (group). Service subscription information is set to wireless sensor networks, then, wireless sensor nodes in the network make the appropriate treatment according to the information from users and publish services results.In this thesis, the technology of wireless sensor-actuator networks closely related to smart home will be introduced in the first. Subsequently we describe the overall structure and various components of the smart home system. The next part is the key point of this thesis. Requirement analysis is carried out to application management module, and databases as well as communication protocol used in the system is designed. Then we introduce the detailed design and implementation of each function module in application management, and a detailed discussion of the optimization of the system is also introduced. The system functional testing and performance testing situations is summarized in the end. |
