Design And Implementation Of Intelligent E-Gateway In Smart Home System

In recent years, The Internet of things has become the global focus area and isconsidered as the most important technology innovation after the Internet. As an importantapplication of The Internet of things, smart home is a market with great potential andfuture prospects for developing. E-Home smart home project developed by TecomCompany includes intelligent e-gateway as the core, as well as home intelligent terminaldevices, door access devices, security devices, and home control devices. In E-Homesmart home system, the intelligent e-gateway management and data transfer command,can realize video call function and intercom call with outdoor phone function based on theSIP and remote monitoring security alarm function and home devices control function bymanaging data and command transmission.Intelligent e-gateway is the management and transfer station for devices control andvoice/video data transmission. First of all, the intelligent e-gateway provides differenttypes of interface to access the smart home system for different types of device, providesan Ethernet port to connect the home intelligent terminal devices, door access devices andconnection to the Internet, provides the DI and DO interface to connect to security devices,provides USB interface with an external USB dongle to connect home devices. Secondly,the intelligent e-gateway provides functions of intelligent devices management, familyintercom and door access control, video surveillance, security alarm management andhome control management. Intelligent e-gateway assigns network address for homeintelligent terminal devices, manages the registration information, maintains networkconnections with devices, receiving and processing message sending from devices. Voiceand video calls between home intelligent terminal devices are based on VOIP, intelligente-gateways establishes call connection and maintains call status. Intelligent e-gatewaymaintains door status and card information. Intelligent e-gateway connects DI withsecurity detectors, DO control with output devices, and can carry out alarm linkage.Intelligent e-gateway can realize the wireless connection and control on home devices viaZ-Wave or ZigBee technology.The implement of intelligent e-gateway provides a guarantee for the functionality and performance of Tecom E-Home smart home system, makes the system to have betterperformance in terms of stability, intelligent and humane, and makes the system to havereceived good market response.
