  However, the technique of Non-Patent Document 1 has the following problems. That is, since the gateway is arranged in the house, it has a communication function and a communication management function for only the devices in the house. For this reason, it is difficult to realize a service that links devices spanning multiple homes (for example, a local security service that rings an alarm device in a home in the area when an intrusion sensor reacts in a home). .

  Further, when the service of Non-Patent Document 1 is expanded to construct a service in which devices spanning a plurality of homes are linked, each service provider installs a server, and a plurality of home service programs cooperate with the server. In general, the address on the external network side of the gateway is not fixed. For this reason, each service provider needs to manage which ID and address should be used to communicate with which device in which house for each service program, and the development / operation burden is large. In addition, there is a psychological barrier for the user that he / she does not want to notify a large number of service providers of in-house information individually (for example, security anxiety that is misused when in-home information is leaked). Also, when providing a plurality of services for a specific terminal group such as “region”, the user needs to make settings individually and is troublesome.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a device management system, a device management method, and a device that can more easily construct a service for linking devices arranged in a plurality of homes.

Note that the device unique ID and the connection destination information have different designation methods depending on the communication type.

  The gateways gw01 to 04 are connected to the virtual gateways vg01 to 03 via a network such as the Internet, for example. The gateways gw01 to 04 may correspond to the virtual gateways vg01 to 03, 1: 1, or may correspond to 1: N or N: 1. Moreover, when the gateway and the virtual gateway correspond to 1: 1, the virtual gateway may be installed in the gateway in the house. Further, the embodiments of the gateways gw01 to 04 may be realized by a mobile phone or a smartphone instead of a device in the house.

  The virtual gateways vg01 to 03 are connected to at least one gateway gw01 to 04 and also connected to at least one community management server c01-03. The virtual gateways vg01 to 03 manage the information of the virtual terminal unit 12 notified from the gateways gw01 to 04 and notify the community management servers c01 to 03.

  Further, the virtual gateways vg01 to 03 have an interface for the user to make settings, and the user uses which operation terminal (not shown) to which virtual terminal unit 12 (device) to which community management server c01 to 03. You can set whether to publish. The virtual gateways vg01 to 03 issue different alias IDs (connection IDs for communication with the community management server) for the community management servers c01 to 03 to the virtual terminal unit 12 set by the user to be published. The alias ID is notified to the community management servers c01 to 03 together with the connection destination information (IP address, etc.) of the virtual gateway and the device type. Further, the virtual gateways vg01 to 03 hold management information in a storage unit (not shown) included in the virtual gateway.

  FIG. 3 shows an example of the management information of the virtual gateway vg01 shown in FIG. The management information illustrated includes an alias ID, a virtual ID (gateway ID + local ID), connection destination information to the gateway, and a device type for each virtual terminal unit 12 included in the gateway gw01. By holding such management information, the virtual gateway can communicate with the virtual terminal unit 12 using the gateway ID and the local ID, and can communicate with the community management server using the alias ID.

  The community management servers c01-03 are connected to at least one virtual gateway vg01-03. Moreover, the community management servers c01-03 may be connected to the service servers s01-02.

  The community management servers c01 to 03 store management information including an alias ID for the virtual terminal unit 12 notified from the plurality of virtual gateways vg01 to 03 in a storage unit (not shown). The community management servers c01 to 03 exist for each community (group) gathered for a certain purpose such as “A elementary school school district”, “B town neighborhood association”, “C corporation”, “D relatives”, etc. The virtual terminal unit 12 disclosed in these units is managed.

Provide service.

  As the gateway, the virtual gateway, the community management server, and the service server, for example, a general-purpose computer system including a CPU, a memory, an external storage device such as an HDD, an input device, and an output device can be used. In this computer system, each function of each device is realized by the CPU executing a predetermined program loaded on the memory. For example, each function of the gateway, the virtual gateway, the community management server, and the service server is the gateway CPU in the case of the gateway program, the virtual gateway CPU in the case of the virtual gateway program, and the community management server program. In this case, the CPU of the community management server executes the program, and in the case of the service server program, the service server CPU executes the program.

  The gateway program, virtual gateway program, community management server program, and service server program are stored on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD-ROM. It can be stored or distributed over a network.

  Next, the operation of this embodiment will be described.

  FIG. 5 shows a sequence 1 in which, when a new device is connected to a home network in a home, information related to the device is virtualized by the gateway and finally notified to the community management server. is there.

  In the home, when a new device is connected to the gateway, the device communication unit corresponding to the communication type from the device in the gateway, the device unique ID transmitted from the device, the connection destination information, the device type (S100), a virtual terminal unit corresponding to the device is generated, and the local ID of the device is paid out (S101). Then, the device communication unit transmits the management information (see FIG. 2) including the paid-out local ID, the communication type, and the information received from the device (device unique ID, connection destination information, device type) to the virtual terminal unit. Set to. The virtual terminal unit transmits the local ID and the terminal type to the corresponding virtual gateway together with the gateway ID and connection destination information (IP address) of the gateway (S102).

  When receiving the information from the virtual terminal unit, the virtual gateway registers the received information in the management information (see FIG. 3) stored in the storage unit (S103). Here, a virtual ID (gateway ID + local ID), gateway connection destination information, and terminal type are set.

  Then, the user accesses the virtual gateway using an operation terminal (not shown) such as a PC, and sets which virtual terminal unit (device) is disclosed to which community management server. That is, the operation terminal receives a user instruction, and transmits a desired community management server, a virtual ID of a virtual terminal unit to be disclosed to the community management server, and a disclosure request designated to the virtual gateway (S104).

  When receiving a disclosure request from the operation terminal, the virtual gateway issues an alias ID for the designated community management server for the requested virtual terminal unit, and updates the management information of the virtual gateway. That is, the paid out alias ID is set in a column corresponding to the virtual terminal unit (virtual ID) designated by the management information (see FIG. 3). Then, the virtual gateway notifies the designated community management server of the alias ID of the virtual terminal unit set in the management information, the connection destination information of the virtual gateway, and the device type (S105).

  The community management server receives the notification from the virtual gateway and registers it in the management information (see FIG. 4) of the community management server.

  FIG. 6 is a sequence 2-1 for performing communication from a service server to a certain device (virtual terminal unit) when a certain community management server has a service contract with a certain service server (S200). As an example of this sequence, there is a case where an alarm device which is a predetermined device is desired to ring. When making a service contract in S200, the community management server transmits management information (see FIG. 4) included in the community management server to the service server of the contract destination.

  First, the service server selects a virtual terminal unit to be communicated based on the management information received from the community management server, and starts communication (S201). In this embodiment, the virtual terminal unit is selected based on the device type. That is, a virtual terminal unit of a predetermined device type is selected as a communication target. Then, the service server transmits the alias ID and communication content of the selected virtual terminal unit to the community management server, and starts communication.

  The community management server refers to the management information (FIG. 4), and transfers the communication content addressed to the alias ID to the corresponding virtual gateway using the connection destination information of the selected alias ID (virtual terminal unit) (S202). ).

  When the virtual gateway receives the communication content transferred from the community management server, the virtual gateway refers to the management information (FIG. 3) and uses the connection destination information and the virtual ID (gateway ID + local ID) corresponding to the alias ID. The communication contents are transferred to the local ID of the gateway to be operated (S203).

  The virtual terminal unit of the local ID of the gateway notifies the device communication unit corresponding to the device unique ID and connection destination information held in the storage unit and the communication content (S204). Is used to notify the communication content to the device indicated by the device unique ID and the connection destination information (S205).

  FIG. 7 is a sequence 2-2 of performing communication from a certain operation terminal to a certain device (virtual terminal unit) in a mode in which the community management server includes an interface for the operation terminal.

  The operation terminal receives a user instruction, accesses a desired community management server, selects a desired virtual terminal unit (alias ID) registered in the community management server, and communicates with the virtual terminal unit To start communication (S211). Thereby, the community management server, the virtual gateway, and the gateway communicate with the device selected in S211 (S212 to S215), similarly to S202 to S205 of sequence 2-1 (see FIG. 6).

  FIG. 8 is a sequence 3-1 for performing communication from a certain device to a service server when a certain community management server has a service contract with a certain service server. For example, there may be a case where an intrusion sensor (device) notifies a service server when an intruder is detected.

  The contracted service server sets in advance in the community management server which device the notification is received from (S300). With this setting, it is assumed that a predetermined flag is set in the device alias ID set by the service server in the management information (FIG. 4) of the community management server.

  A certain device communicates with the device communication unit of the gateway using a device-specific protocol (S301). The device communication unit notifies the corresponding virtual terminal unit of the communication content (S302), and the virtual terminal unit notifies the virtual gateway of the communication content, the local ID of the virtual terminal, and the gateway ID (S303). .

  Based on the management information (FIG. 3), the virtual gateway notifies the community management server, in which the alias ID is set corresponding to the gateway ID and local ID notified from the gateway, together with the alias ID (S304). . The community management server receives the notification from the virtual gateway, and when the alias ID of the received notification is the alias ID for which the flag is set in S300, notifies the service server of the communication content together with the alias ID (S305).

  FIG. 9 is a sequence 3-2 in the case where the virtual gateway includes an interface for the operation terminal and performs communication directly from one device to another device without using the service server.

  The user uses an operation terminal (not shown) such as a PC to access the virtual gateway and sets which virtual terminal unit (device) communicates with which virtual terminal unit (device) outside the home. That is, the operation terminal accepts a user instruction and assigns the alias ID of the desired virtual terminal unit that is the communication source, and the alias ID and virtual gateway ID of the desired virtual terminal unit outside the home that is the communication destination to the virtual gateway. (S400). When receiving the setting request from the operation terminal, the virtual gateway sets the alias ID and the virtual gateway ID set as the communication destination in the requested alias ID of the virtual terminal unit, and management information of the virtual gateway (FIG. 3) Update.

  The communication source device communicates with the gateway device communication unit using a device-specific protocol (S401). The device communication unit notifies the corresponding virtual terminal unit of the communication content (S402), and the virtual terminal unit notifies the virtual gateway of the communication content, the local ID of the virtual terminal, and the gateway ID (S403). .

  Based on the management information (FIG. 3), the virtual gateway is set in S400 together with the alias ID and the communication content in the community management server in which the alias ID is set corresponding to the gateway ID and local ID notified from the gateway. The communication destination alias ID and virtual gateway ID are notified (S404). The community management server receives the notification from the virtual gateway, and notifies the received notification content to the communication destination virtual gateway together with the communication destination alias ID. Thereafter, similarly to S203 to S205 of the sequence 2-1, communication is performed with respect to the device designated as the communication destination in S400.

  In the present embodiment described above, the gateway includes a device communication unit and a virtual terminal unit, thereby converting (unifying) devices that use various communication protocols into virtual terminals that communicate with one protocol. It is possible to realize services using various devices.

  Further, in this embodiment, the virtual gateway manages the state (IP address change, etc.) of the gateway and the virtual terminal connected to the subordinate, so that the higher-order servers (community management server, service server) It becomes unnecessary to directly manage the actual connection state. In addition, the virtual gateway manages the disclosure / non-disclosure of the virtual terminal unit to a higher-order server, and the home information is spread by issuing a temporary connection ID (alias ID) to the disclosure destination. Leakage can be prevented.

  In this embodiment, the community management server can manage a plurality of in-home devices in a community (group) having a certain purpose, and can reduce the burden of selecting and setting devices when using the service. . This eliminates the need for the service server to search for a target device from devices all over the world, and reduces the burden on the user for setting each of the partners permitted to communicate with a certain device.

  Further, according to the present embodiment, the service server can more easily construct a service using a plurality of in-home devices. In this case, the service provider does not need to manage which ID and address should be used to communicate with which device in which house, and the development / operation burden can be reduced. In addition, the user only needs to set whether the terminal is open or closed in units of communities (groups) having a certain purpose, and the setting burden is small compared to the case where the setting is performed individually.

  Also, the community management server or service server is not notified of the ID or address of the device (virtual terminal unit) directly, and the alias ID obtained by the community management server or service server cannot be reused. Even when information is leaked, it is impossible to communicate using the information, so that the psychological barrier of the user can be reduced.

  In addition, this invention is not limited to the said embodiment, Many deformation | transformation are possible within the range of the summary.
