N: network

The present invention provides a home network system including a home server capable of controlling an operation of a home appliance connected to a network constructed in a building, wherein the client device or an external server transmits and receives a message based on a different communication standard from the home server. The present invention relates to a home network system that can expand the scope of network connection by facilitating the development of a home network system by using a more intuitive message standard so as to be associated with the system.

1 illustrates a state in which a message is transmitted and received between a home server and an external server of a conventional home network system, and a conventional problem will be described in detail with reference to this.

The recently developed home network system enables the mutual operation control by connecting one or more home appliances and a home server 10 that can centrally control the home network system N in a building.

The home server 10 transmits and receives a message based on a predetermined communication standard, which will be described by exemplifying UPnP (Universal Plug and Play) applied to many home appliances as a first communication standard. The home server may recognize only a client device that issues a message based on the first communication standard.

However, since this is not a communication standard that is forcibly defined in the development of home appliances, home servers, and external servers 20, the second and third communication standards may be adopted depending on the manufacturer or the product. At this time, although the client device of the manufacturer is connected to the same network (N), due to different communication standards, normal message transmission and reception with the home server was not possible.

This not only has a problem of impairing the compatibility of the client appliances connected to the home server 10 through a network N, and also develops an external server 20 that transmits and receives messages with the home server through the Internet. It has also constrained the environment.

That is, as shown in FIG. 1, a message is communicated with the external server using a message of a first communication standard applied to the home server 10 to provide a home network service to a remote user connected to the external server 20. Sending and receiving.

That is, the external server 20 is different from the manufacturer, and even though the application is different from the home server 10, the first communication standard applied to the home server for the connection with the home server The system had to be identified and the system issued a message of the corresponding specification.

When the external server 20 transmits a control command message requesting operation control or status monitoring, the home server 10 responds to the control result message accordingly, so that the external server manufacturer can intuitively understand the message. After grasping a difficult communication standard, it was necessary to start development.

Therefore, this hindered the development speed of the manufacturer of the external server 20 or the network home appliance, and as a result, there was a disadvantage in that the network connection and compatibility through the home server 10 were reduced.

The present invention has been made to solve the above-mentioned problems of the prior art, the object of which is to provide a new communication standard of intuitively understandable message, so that the development of a client or external server associated with the home server even if the manufacturer is different It is to provide a home network system that can easily improve the compatibility, linkage function of the network system through the home server ultimately.

Home network system according to the present invention for solving the above problems is one or more home appliances connected via a network network built in the building, and the external to remotely issue a control command message for the operation control or status monitoring of the home appliances The server controls the operation of the home appliance connected to the network according to the control command message or the self-input control command received from the external server through the Internet network, and generates a control result message to respond to the external server. The control command message includes a header in which total message length information is embedded, a command index indicating whether a request or response is received, a command code indicating whether an operation control command or a status check command is included, and which is to be controlled. Command definition with built-in device information, arguments set for the corresponding operation Including field it characterized by forming a standard.
Alternatively, the control result message may include a header in which total message length information is embedded, a command index indicating whether a request or response is received, a command code indicating whether it is a response to an operation controlled result or a notification of a state change, and success of operation control. Or it comprises a command definition field indicating a failure result characterized in that the specification is achieved.
