Description

A Multifunctional Gateway Applied to Smart Home

technical field

The invention relates to the technical field of smart home, in particular to a multifunctional gateway applied to smart home.

Background technique

Smart home connects various devices in the home (such as audio and video equipment, lighting system, curtain control, air conditioning control, security system, digital cinema system, audio and video server, shadow cabinet system, network appliances, etc.) Home appliance control, lighting control, telephone remote control, indoor and outdoor remote control, anti-theft alarm, environmental monitoring, HVAC control, infrared forwarding and programmable timing control and other functions and means. Gateway (Gateway) is also called Internet connector and protocol converter. The gateway implements network interconnection above the network layer and is the most complex network interconnection device, which is only used for the interconnection of two networks with different high-level protocols. Gateways can be used for both WAN interconnection and LAN interconnection. A gateway is a computer system or device that acts as a switch. Used between two systems with different communication protocols, data formats or languages, or even completely different architectures, a gateway is a translator. Unlike bridges, which simply convey information, gateways repackage received information to suit the needs of the destination system. With the rise of multiple sensor terminal manufacturers, the interfaces, commands, and communication methods of sensors are also different. The traditional smart home gateway has a single information function and cannot realize information transmission between multiple different networks. Therefore, we propose A multifunctional gateway applied to smart home.
