Embodiment Construction

[0027] Such as image 3 As shown, the home network system 100 provided by the present invention includes at least one master device 50 connected to the bus network 90 and a plurality of slave devices 60 , 70 , 80 . In addition, it includes a gateway 30 connected to the outside; and a network manager 40 connected to the gateway 30 to provide Internet services and having a function of setting and initializing the environment of home devices within the home network system 100 . Wherein, the main control device 50 has the same function as the main control device in the prior art, and the network manager 40 has similar functions to the main control device 50 except that it can provide Internet service. However, for the convenience of the following description, it is assumed that the network manager 40 only has a bridge function for connecting to the Internet, and only the main control device 50 exists in the home network system 100 . Here, the bus network 90 may be a line provided...

Abstract

The home network system includes first and second home electrical devices, and a communication network for connection of the device above. The first home electrical device transmits packet indicating its required buffer size to second home electrical device, and the second home electrical device transmits the response packet containing information of buffer size. The first home electrical device makes storage for standard buffer according to the information of buffer size in the response packet, and then switches the packet transmitted to second home electrical device according to the size of standard buffer.

Description

technical field [0001] The present invention relates to a home network system and its communication method, in particular to a home network system and its communication method which can convert and transmit data packets according to the buffer size in the home equipment. Background technique [0002] At present, the home automatic control system that uses the remote automatic control technology to control the household equipment inside the home or outside the home has reached the commercial stage. The initial home automatic control system was only at the level of using telephone or infrared rays to control each device separately, and there was no connection between each device, but recently there has been a communication device to build a network between various household devices, and set up a control system. Network controller to comprehensively manage the network. figure 1 It is a schematic diagram of a common home network system. Such as figure 1 As shown, a home netwo...
