Description

Home Gateway System for Smart Home

technical field

The invention relates to the field of smart home, in particular to a home gateway system suitable for smart home, which realizes protocol conversion and data transmission between the smart home indoor network and external network.

Background technique

In recent years, with the improvement of the economic level and the development of social informatization, people have put forward higher requirements for the safety, comfort, intelligence and energy saving of traditional houses, so the smart home system has emerged as the times require. The smart home system uses the residence as a platform to apply modern communication technology, computer technology and electronic technology to realize functions such as intelligent control of household appliances and real-time monitoring of the home environment, so as to build a more perfect living environment.

Considering equipment installation and user experience, the current research and popular smart home systems mainly use wireless communication to build an indoor network to complete functions such as information transmission and control of indoor equipment. At present, the relatively mature wireless communication technologies mainly include Bluetooth, Wi-Fi, ZigBee and radio frequency. Among them, Bluetooth technology has a short communication distance and is a point-to-point communication method, which is difficult to apply to families with multiple electrical appliances; Wi-Fi technology consumes a lot of power, is not economical, and is more complicated to configure; in comparison, ZigBee as a A low-speed, low-power, low-cost wireless network technology with high reliability and self-organizing network features, which is very suitable for the application scenario of smart home system indoor network. The present invention is also mainly aimed at the smart home system adopting ZigBee communication technology.

In order to realize remote data transmission, the smart home gateway not only ensures the normal operation of the indoor ZigBee network, but also needs to connect to the external Internet network, and the communication protocols of the two are not the same. At the same time, the network status of each family is different. If the home network interface is not a public network IP, it is difficult for the mobile phone or remote computer client to directly establish Socket communication with the home gateway. Ordinary embedded web gateways cannot achieve the effect of remote monitoring of household appliances .

After searching the existing documents, it is found that the Chinese patent application number 2013106234516 and the invention titled "Smart Home Gateway" disclose a smart home gateway technology. Although this technology solves the problem of data transmission between the indoor network and external network of the smart home system, and considers the differences in network conditions of different families, it uses GPRS modules, WiFi modules, etc. to establish remote communication connections, but the system structure is complicated and the cost is high. The functions of each module are repeated, which essentially does not solve the problem of remote communication between the client and the gateway when the home network entrance is not a public network IP.
