The Intelligent Power Utilization Interactive System And Protocol Conversion

As one of the main features of the smart grid, interaction is significant to encourage users to participate in the operation and management of electricity system,and also to construct suitable intelligent power utilization interactive system. Among the broad range of the intelligent power utilization interactive system, smart home system is the the most closely related one to our daily life, because of the various home-area networks existed in smart home system, lots of research focus on protocol conversion. Designing suitable software architecture and power utilization applications for users and researching protocol conversion of smart home access gateway are the key to realize interaction of intelligent power utilization system.Based on the research of interaction of intelligent power utilization system, firstly a overall design of intelligent power utilization interactive system is given, including system composition and interactive program. Combining with device interaction, the function of interactive program are analyzed in detail, and a design of software structure of gateway used in smart home system is presented to support the interactive program. Then a design of protocol conversion software of the gateway is proposed, consisting of data analysis module, control module and network transmission module, an address mapping table is set up in control module to provide addressing method for the devices in home. A specific example is offered to illustrate the protocol conversion process. This design is adapted to the situation of various home-area networks existed in smart home system, it can support protocol conversion between any two networks. At last, a design of application-layer communication protocol is given as a supplement, focused on analyzing the interactive mechanisms of the protocol and the type of interactive messages.
