Description

Home Appliance Network System Including Bridge device and Its Operating Method

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a home appliance network system having a bridge means, and more particularly to a home appliance network system in which a home appliance for a first communication standard and a home appliance for a second communication standard are connected. The present invention relates to a home appliance network system having bridge means for connecting communication of home appliances having different communication standards from each other so as to control the operation of the second communication standard home appliance according to a control command.

A home appliance network system that transmits and receives data such that a plurality of home appliances are connected to a network network to enable mutual control can not only connect a plurality of home appliances having a first communication standard but also a second communication standard different from the first communication standard. It can connect a plurality of home appliances having a.

Especially, the communication standard applied to many home appliances is UPnP (Universal Plug and Play), which is developed by leading companies such as Intel, 3COM, Cisco, Dell, IBM, Ericsson, Nokia, Philips, LG, and Samsung. The present invention has been applied to a home appliance network system, which is referred to as a first communication standard for convenience. However, in the home appliance network system, the home appliance for the first communication standard can be mutually controlled with the home appliance to which the same first communication standard is applied, but is connected to the same network as the other home appliance to which the second communication standard is applied. Due to the different communication standards, mutual control was not possible. Therefore, although consumers have purchased home appliances that support the home networking function, they are unable to use home appliances efficiently due to their incompatibility due to other communication standards, and support communication standards different from those of the first communication standard. In the case of manufacturers developing home appliances, costs for manufacturing and selling home appliances will increase, such as the need to separately manufacture a device for supporting the first communication standard.

The present invention has been made to solve the above-mentioned problems of the prior art, the object of the first communication standard home appliance in the home appliance network system connected to the second communication standard home appliance, the first communication standard home appliance It is possible to increase the convenience of the user's control of the home appliance by controlling the second communication standard home appliance having a different communication standard through the device, and to efficiently interoperate a plurality of home appliances using different communication standards. It is to provide a home appliance network system having a bridge means.

1 is a view showing an example of the configuration of a home appliance network system having a bridge means of the present invention;

2A, 2B, 2C and 2D are operational flowcharts of the home appliance network system having the bridge means of the present invention.
