Digital home network system and method

Abstract

An embodiment of the invention discloses a digital home network system, which comprises an intelligent home network server institute for the history of natural science (IHNS), a home internal subnet and a home gateway. The IHNS is used for managing home networks in a community, shares load of the home gateway of each home network, verifies user identities and safety of operation requests, and sends remote control instructions or query requests to the home networks. The home gateway is used for analyzing the remote control instructions or the query requests, conducting command operation in the home internal subnet according to the instructions or the requests, and conducting corresponding control and simultaneously sending corresponding results back to a client side if the analyzed instructions or requests relate to device control. The embodiment of the invention further discloses a meter reading method based on the digital home network system. Through the embodiment of the system and the method, the IHNS is introduced for sharing load of the home gateway, simultaneously rich application services are provided, and user information safety is ensured.

Description

technical field [0001] The invention relates to the technical field of digital home, in particular to a digital home network system and method. Background technique [0002] In recent years, with the continuous expansion of the digital home industry and the continuous in-depth development of family digitization, the home network architecture, which plays a pivotal role in the family, has also received continuous attention from academia and industry. It is of great significance to propose an efficient, flexible and stable home network architecture. It is generally believed that the home network should provide the following functions: (1) Control and management of electrical equipment. Control devices such as lights, water heaters and air conditioners through household wireless devices such as remote controls, personal phones and the Internet. (2) Home security. Through home cameras, temperature and humidity sensors, etc., it is possible to monitor home security defenses, f...

AI Technical Summary

Problems solved by technology

[0004] But the existing home gateway is overloaded and the design is too complex

The home gateway undertakes the data exchange of the home internal network, the data exchange between different subnets, and the data exchange between the home network and the external network. Therefore, the data load of the home gateway is too large, and different devices require different management requirements, which will lead to The design of the gateway is too complex

The structure of the network is not flexible enough, and the topology is single

The architecture of this kind of home network belongs to the tree network structure, which not only has very high requirements on the home gateway, but also seriously affects the flexible expansion of subnets, the addition of new networks, etc.
