Design And Implement Of Middleware For Intelligent Home Network Based On BACnet

Intelligent Home, which is a branch of Artificial Intelligence, brought out by the increasing needs of energy saving, security, comfort and efficiency of people. As we know, intelligent home is the core of automatic system in facility, which function is focused on system setting, device managing and real-time monitoring. And the performance of building automation control system is directly depended on the reliability of software system and the integrality of function. The prime purpose of BACnet is to provide an interoperation method for building automation control system.. In the implement of intelligent home, BACnet has become one of the choices of the data transport by right of its opening, simpleness, practicality, and easying to integrate with various kinds of physical network. In this paper, the intelligent home system is built base on BACnet protocol.In the intelligent home network which based on BACnet protocol, a reliable, extensible and transparent platform is provided for the remote web control through the use of the middleware, with which fits B/S structure together. In this paper, this paper gives an analysis on the principle and model of middleware of central control module, as a key part of Home Information Control Center (HI2C), which is the core of intelligent home networks. In the data stream between uses and HI2C, this middleware can transfers request from web to BACnet standard service, that means it offers an efficient and agile method of remote application calling. In the data stream within home network, this paper analyses protocol conversion and database access technology, and use middleware to offer the other module deal transfer and store methods which has low coupling feature. After that, the implement will be described in detail, and this paper gives the code and test result. At last, this paper summarizes the main part of this paper, and gives a prospect.
