Problems solved by technology

[0006] However, there is a problem in the conventional technology that when disclosing the information of the devices connected to the own network and the information about the attributes and data corresponding to the devices to the network of different protocols, the data to be disclosed is also defined for each device, Therefore, not only the workload is huge, but different protocols define the same machine differently, which leads to many difficulties in the development of controllers that control machines connected to networks with different protocols.
[0007] Also, specifically, to connect the ECHONET equipment and AV equipment in the home, it is necessary to connect the gateway function of the ECHONET protocol and the UPnP protocol for the AV equipment. However, the current ECHONET standard does not specify a specific gateway. function, so it is not possible to realize the mutual integration of ECHONET equipment and AV equipment in the home

Embodiment 1

[0067] FIG. 1 is a system structural diagram of a home network composed of multiple protocols in the home network according to Embodiment 1 of the present invention.

[0068] For the two protocols shown in FIG. 1 , for example, let the protocol A12 be UPnP, and let the protocol B13 be ECHONET. The structure of the home network is such that the controller device 14 is connected to the protocol A12, and the terminal 15, the terminal 16, and the terminal 17 are connected to the protocol B13.

[0069] The terminal 15, the terminal 16, and the terminal 17 are machines such as an air conditioner or a refrigerator. Furthermore, the home network system includes the gateway device 11 connected to both the protocol A12 and the protocol B13. The controller device 14 connected to the protocol A12 and the terminals 15 , 16 , 17 connected to the protocol B13 realize mutual connection between different protocols through the gateway device 11 .

[0070] The controller device 14 obtains info...

Embodiment 2

[0130] Embodiment 2 of the present invention will be described below with reference to the drawings.

[0131] FIG. 3 is a structural diagram showing the protocol stack of the controller device 14. In the home network of Embodiment 2 of the present invention, the network connected to the controller device 14 is different from the protocol network connected to the terminal 15. The terminal 15 is a control object.

[0132] The controller device 14 includes a protocol A communication processing unit 30, a device description detection processing unit 31, a device analysis processing unit 32, a service description detection processing unit 33, a service analysis processing unit 34, an event reception processing unit 35, a device control processing unit 36, Data storage unit 37 .

[0133] The device description detection processing unit 31 sends discovery request data to detect devices connected to the network when the controller device 14 is connected to the network, and when recei...

Embodiment 3

[0148] Embodiment 3 of the present invention will be described below with reference to the drawings.

[0149] FIG. 9 is a system configuration diagram showing the system configuration of a home network composed of multiple protocols in the home network according to Embodiment 3 of the present invention.

[0150] The gateway device 11 receives the protocol conversion table 51 about the name of the machine, the conversion table 61 about the attributes and data common to the machines, and the conversion table 71 about the attributes and data about each machine from the central server 91 through the Internet 92, and updates the protocol conversion table Each table stored in the storage unit 28 .

[0151] Similarly, when the gateway device 11 receives a template of device information data from the center server 91 via the Internet 92, the device description template storage unit 25 updates the template or adds it as a new template.

[0152] Furthermore, when the gateway device 11 ...

Abstract

Provided is a gateway device for opening information on devices or services to a device to be connected with the networks of protocols of different kinds. The gateway device (11) includes a device description creation processing unit (24), a device description template holding unit (25), a service description creation processing unit (26) and a service description template holding unit (27). The service description creation processing unit (26) classifies the services and attributes corresponding to the individual devices, into property types or corresponding control models, and creates the service information description or the public information automatically, according to the rules regulated for every property types.

Description

technical field [0001] The present invention relates to a gateway device. The gateway device refers to a gateway device connected to networks of the two protocols when a terminal device as a control device and a terminal device as a non-control device are respectively connected to networks of different protocols. In particular, it relates to a gateway device including an open method for disclosing the connection status of terminal devices to the network and the services and attributes that each terminal device can support to a control device connected to a network of a different protocol. Background technique [0002] Conventionally, there have been descriptions of a structure in which applications, services, and devices describe their own capabilities and publish them to other applications, services, and devices, and integrate various networks into a unified framework to make Various network entities located in different networks discover and interact with each other.
