Problems solved by technology

Europe has formulated the EIB standard in terms of home automation, but its system is complex and the cost is too high, so it is difficult to promote in domestic applications
[0004] Looking at the above-mentioned types of home automation network technologies, they are not completely suitable for ordinary Chinese families. We need a communication protocol to realize the control and resource sharing of various devices in the home network system.

Embodiment Construction

[0021] see figure 1 , the home control network includes a network bus 1 , each network node 2 , each functional module 3 , each device 4 and a mobile terminal 5 . Each functional module 3 is connected to a network node 2 , each network node 2 is connected to the network bus 1 through a connecting terminal, and each device 4 is respectively connected to each functional module 3 . The home control network adopts a single bus structure, and the network node 2 can be connected to the bus at any time and anywhere. Various data are allowed to be transmitted on the bus, from simple control commands to complex information such as text files. The topology of the home control network is basically in the form of a bus, or it can be a tree or daisy chain, or it can be a free topology. The specific nodes connected to the network can be designed according to user requirements and implementation convenience. The maximum number of nodes that can be connected is determined by the network dri...

Abstract

A household control network protocol realizes control to the equipments in household network system and resources sharing. This invention relys on ISO standard and realizes a physical layer, data link layer and an applied layer characterizing in that the interface design in the physical layer is to receive changes on network communication line, not necessary to define physical medium data link layer judges and processes data information from a connection adaptive layer to analyses and processes data from a control interface delivered to the connection adaptive layer.

Description

[0001] Field [0002] The invention relates to a home control network protocol, belonging to the technical field of home automation networks. Background technique [0003] As modern families have higher and higher requirements for residential intelligence, the automation and intelligent control of household appliances and equipment, the network and intelligence of resource use and payment methods, and the demand for home-based work models have become people's Concerns. Home control network technology became popular in the United States as early as the 1970s. X-10, LonWorks launched by Echelon in the United States, and CEBus (Consumer Electronic Bus) launched by the American Electronics Industry Association all adopted control network technology and formulated a unified Communication Protocol, a communication protocol, through which each device in the network system can share resources. However, X-10 products are mainly used in the renovation of old houses. If the house is de...
