Home gateway

Abstract

The invention discloses a home gateway which can realize the remote control and management of various household devices which are commonly used. The home gateway mainly comprises a microcontroller core unit, and an internal network interface and an external network interface which are separately connected with the microcontroller core unit, wherein the internal network interface comprises an RS-232 serial interface, an RS-485 serial interface, a USB serial interface, a PS / 2 interface, an Ethernet interface, an infrared interface and a common I / O port; and the external network interface comprises an Ethernet interface which can be connected with the Internet and a wireless interface of a GPRS network. The different interfaces of the internal network can be used to connected with various common household devices, the interfaces of the external network are used to connected with remote control devices, and different remote control devices, namely the computer or cell phone can be selected according to demands to realize the remote control of any household device conveniently and quickly in real time. The home gateway has simple structure and convenient and fast operation, and can be widely used in the remote control and management of household devices.

Description

technical field [0001] The invention relates to a household remote control device, in particular to a household gateway for remote control of household equipment. Background technique [0002] At present, the equipment generally owned in the family can be roughly divided into three categories: one is information equipment represented by home computers, notebook computers, and handheld computers; the other is traditional equipment represented by televisions, DVDs, digital cameras, and audio Entertainment equipment; the third category is household equipment related to the daily life of the family, including refrigerators, washing machines, lighting and home security systems. Smart home means that these devices in the home form a home internal network and connect to the external network through a home gateway for remote control and management. The home gateway is an important part of the smart home, and it is an intermediate device that realizes the communication between the i...

Problems solved by technology

But this kind of home gateway also has its limitations, it can only be applied to the families that have established Ethernet, wireless local area network 802.11b and automatic control network CEBus, and because it is more complicated to set up these family internal networks, the investment required is also relatively large. Therefore, in the current Chinese families, the establishment of wireless LAN 802.11b and home automatic control network CEBus has not yet been popularized. Therefore, only through the Ethernet interface, home entertainment network A / V cable interface, and 1394 interface It is impossible to complete the connection of all household devices, and the remote control of some household appliances needs to use the infrared interface; in addition, this kind of home gateway can only be connected to the external network through the Internet, so the remote control of household devices must be in It can be operated on a fixed computer that can be connected to the Internet, and its functions cannot be realized without the computer, so it is often inconvenient to use and cannot fully meet the needs of modern people's lives, that is, the requirements for convenient operation and use anytime, anywhere
