The Design of Smart Home Gateway Based On KNX Bus

Smart home gateway is the key to external access networks and smart home network connection device, and it can accept signals from different external networks, transmitting signals to an smart home device via home network to control and manage a home network internal device, introduces the technical characteristics and advantages on the basis of the KNX bus and combined with the latest microcontroller technology and network communication technology etc, puts forward the design of smart home gateway based on KNX bus, Described in detail the smart home gateway in Ethernet interface, KNX module and the design and implementation process of main controller. The work and research will help to break the monopoly of the KNX technology which is controlled by foreign companies and greatly reduce price of KNX product. Besides, the localization process of KNX technology and products will be effectively promoted. Ultimately, it is achieved that the smart home comes into the lives of people.
