That is, the technology described below can be applied to various facilities and detached houses.

  As shown in FIG. 2, the housing complex 10 includes an intercom system. The intercom system includes a dwelling unit 21 and a doorphone slave unit 22 that function as doorphone master units arranged in the dwelling unit 11 of the apartment house 10, and a common unit 23 and a management room master unit 24 that are arranged in the common unit 12 of the apartment house 10. With. A common example of the shared machine 23 is a lobby interphone arranged in the entrance lobby. In the case of an apartment house where facilities such as a kids room, an exercise facility, and a doctor's office are arranged side by side, these facilities are also included in the shared unit 12, and the shared machine 23 may be arranged in these facilities. The management room base unit 24 is arranged in the manager room.

  The dwelling unit 21 and the door phone slave unit 22 are connected via a dwelling unit dedicated line 25. On the other hand, the dwelling unit 21, the shared machine 23, and the management room base unit 24 are connected to the local communication line 26.

  A control device 27 is connected between the dwelling unit 21, the shared machine 23, and the management room master unit 24. Up to 16 control devices 27 can be connected in parallel, and 100 to 1000 dwelling units 21 are connected to the control device 27 in a large-scale apartment house. The control device 27 performs one-to-one communication among the dwelling unit 21, the shared device 23, and the management room base unit 24, except when notifying the entire building. For example, when a dwelling unit 21 of a specific dwelling unit 11 is called from the common unit 23 arranged in the entrance lobby, the dwelling unit 21 and the dwelling unit 21 until the call is terminated between the dwelling unit 21 and the common unit 23. The shared machine 23 occupies the local communication line 26. In addition, when the some control apparatus 27 is connected in parallel, it is also possible to call the some dwelling unit 21 from the common machine 23 through the some control apparatus 27. FIG.

  The intercom system described above forms a closed system in the apartment house 10 and can be used independently of other systems. This intercom system can connect the condominium gateway 28 to the control device 27 in order to cooperate with an external system.

  By the way, the dwelling unit 21 arrange | positioned for every dwelling unit 11 is equipped with the connection port (not shown) which connects the gateway apparatus 30, respectively. The gateway device 30 has a function of converting a protocol between the above-described intercom system and the IP network.

  The IP network is constructed not only as a telecommunications network used within the range of the dwelling unit 11 in which the dwelling unit 21 is arranged, but also includes a telecommunications network used outside the range of the dwelling unit 11. There is also a case. The telecommunication network (hereinafter referred to as “dwelling unit network”) NT1 used within the range of the dwelling unit 11 where the dwelling unit 21 is disposed may use either a wired communication path or a wireless communication path.

  When using a telecommunication network (hereinafter referred to as “external network”) NT2 used outside the range of the dwelling unit 11, a wireless LAN router 41 is provided between the dwelling unit network NT1 and the external network NT2. In the illustrated example, the wireless LAN router 41 communicates with the gateway device 30 using a wired communication path conforming to the Ethernet (registered trademark) protocol. However, the wireless LAN router 41 may communicate with the gateway device 30 using a wireless communication path.

  The external network NT2 in the illustrated example is a telecommunications network (hereinafter referred to as a “premises network”) NT21 inside the apartment house 10 and a telecommunications network such as the Internet outside the apartment house 10 (hereinafter referred to as “wide area network”). ) NT22. However, the external network NT2 may be only one of the local network NT21 and the wide area network NT22.

  When the external network NT2 includes a local area network NT21 and a wide area network NT22, a network device 42 shared in the apartment house 10 is provided between the local area network NT21 and the wide area network NT22. The network device 42 preferably includes a router or WLC (Wireless LAN Controller) and a VPN (Virtual Private Network) device. The configuration of the network device 42 is an example, and other configurations may be adopted.

  Further, in the illustrated example, a wireless LAN router 43 is connected to the local area network NT21, and a wireless LAN access point 44 is connected to the wide area network NT22. The wireless LAN routers 41 and 43 and the wireless LAN access point 44 as wireless access devices are all equipped with WiFi (registered trademark). The wireless LAN router 41 is connected to the wireless LAN router 41 of another dwelling unit 11 through the local network NT21. The wide area network NT22 may include a mobile telephone network. In this case, a base station of the mobile telephone network is used as the wireless access device.

  The number of wireless LAN routers 41 is normally one for each dwelling unit 11, but a plurality of wireless LAN routers 41 may be arranged in one dwelling unit 11. The wireless LAN router 43 is disposed in the common unit 12 of the apartment house 10, and the location and number of the wireless LAN routers 43 are determined according to the size and number of the common unit 12.

  The above-described configuration is an example, and the IP network is constructed in various forms such as when the external network NT2 is not included, the external network NT2 does not include the local network NT21, and the external network NT2 does not include the wide area network NT22. Is possible. Further, when the local network NT21 is not included in the IP network, the wireless LAN router 43 is unnecessary, and when the wide area network NT22 is not included in the IP network, the network device 42 and the wireless LAN access point 44 are not required.

  Hereinafter, the configuration of the gateway device 30 will be described with reference to FIG. The gateway device 30 includes a first interface unit (hereinafter referred to as “first I / F unit”) 31 to which the interphone system is connected and a second interface unit (hereinafter referred to as “second interface”) to which the IP network is connected. 32). The first I / F unit 31 is connected to the dwelling unit 21, and the second I / F unit 32 is connected to the wireless LAN router 41. The second I / F unit 32 is connected to the wired communication path in the configuration example shown in FIG. 2, but may be configured to use a wireless communication path. If the second I / F unit 32 is configured to use a wireless communication path and is equipped with WiFi (registered trademark), the wireless terminal 50 and the gateway device 30, which will be described later, are used without using the wireless LAN router 41. It becomes possible to communicate between.

  Between the first I / F unit 31 and the second I / F unit 32, a policy routing unit 33 that determines routing according to a set policy, and protocol conversion between the intercom system and the IP network. And a protocol conversion unit 35 to perform. The policy routing unit 33 manages routing using the relationship information set in the relationship management unit 34. The relationship information set in the relationship management unit 34 associates the dwelling unit 21 and the management room master unit 24 connected to the intercom system with the wireless LAN routers 41 and 43 and the network device 42 connected to the IP network.

The policy set in the policy routing unit 33 and the relationship information set in the relationship management unit 34 are set in the gateway device 30 using a setting device (not shown). The gateway device 30 may be provided with a dedicated connection port for connecting the setting device. Preferably, the gateway device 30 passes through at least one of the first I / F unit 31 and the second I / F unit 32. It is desirable to capture information from the setting device. In this case, for example, the management room base unit 24 may have a function as a setting device, and the policy and related information may be set in the gateway device 30 from the management room base unit 24 through the dwell unit 21. Or you may employ | adopt the structure which sets a policy and related information to the gateway apparatus 30 by using the dwelling unit 21 as a setting apparatus, or making the radio | wireless terminal 50 mentioned later function as a setting apparatus.

  The policy set in the policy routing unit 33 is information for linking the intercom system and the IP network. Below, the policy when the dwelling unit 21 receives a call signal as a control signal is demonstrated. The calling signal may be received by the dwelling unit 21 from the doorphone slave unit 22 or the shared unit 23, or may be received from the management unit base unit 24 or the dwelling unit 21 of another dwelling unit 11. The dwelling unit 21 has a function of transmitting a notification signal to the gateway device 30 when the call signal is received. However, whether or not to transmit the notification signal to the gateway device 30 is selected by the dwelling unit 21. Here, the case where the state which transmits a notification signal to the gateway apparatus 30 is selected is assumed.

  When the policy routing unit 33 receives the notification signal from the dwelling unit 21, the policy routing unit 33 selects whether to transmit the call signal within the range of the intercom system or to transfer the notification signal to the IP network according to the set policy. . When the dwell unit 21 receives the call signal and transmits the call signal in the range of the intercom system, the gateway device 30 instructs the dwell unit 21 to transmit the call signal to the management room base unit 24.

  On the other hand, when notifying the IP network that the dwell unit 21 has received the call signal, the policy routing unit 33 determines a range for transferring the notification signal in the IP network according to the policy. The notification range in this case is selected within the range of the dwelling unit 11, within the range of the apartment house 10, a specific range of the apartment house 10, or outside the range of the apartment house 10 alone or in combination. That is, the policy routing unit 33 selects a partner to which the notification signal is transferred from the wireless LAN routers 41 and 43, the network device 42, and the wireless LAN access point 44 in accordance with the set policy. The protocol conversion unit 35 transfers the notification signal from the first I / F unit 31 to the second I / F unit 32.

By the way, since the IP network includes wireless LAN routers 41 and 43 and a wireless LAN access point 44 each equipped with WiFi, it is possible to communicate with a wireless terminal 50 registered in advance. The wireless terminal 50 is preferably a mobile terminal that can be carried by a user, but a personal computer that functions as a wireless LAN terminal can also be used. The mobile terminal only needs to include a display device having a relatively large screen and to be able to input and output audio, and preferably a smart phone or a tablet terminal is used. A terminal (including a personal computer and a television receiver) connected to the dwelling unit network NT1 can be used similarly to the wireless terminal 50.

  The relationship information set in the relationship management unit 34 is information for associating the gateway device 30 with the wireless terminal 50, and the relationship information is set in the gateway device 30 connected to the dwelling unit 21. The machine 21 and the wireless terminal 50 are associated with each other. That is, when the dwell unit 21 receives the calling signal, the notification signal is transferred only to the specific wireless terminal 50 in which the related information is set. Since the dwelling unit 21 is arranged for each dwelling unit 11, it is possible to transmit a notification signal only to a specific wireless terminal 50 managed by a resident of each dwelling unit 11 if the related information is appropriately set. .

  As is clear from the above description, the relationship management unit 34 specifies the notification destination wireless terminal 50 that notifies that each dwelling unit 21 has received the call signal, and the policy routing unit 33 Limit the communication range. Therefore, when a specific wireless terminal 50 corresponding to the dwelling unit 21 is present in a specific range, a notification signal can be transferred to the wireless terminal 50.

  When a plurality of types of policies are set in the policy routing unit 33, it is desirable that the policies can be selected. Since the resident of the dwelling unit 11 selects the policy, the dwelling unit 21 or the wireless terminal 50 is used. By making the policy selectable, the resident of the dwelling unit 11 in which the dwelling unit 21 is arranged can select the policy according to the place where the wireless terminal 50 is carried. That is, the gateway device 30 does not generate unnecessary traffic on the IP network, but generates traffic within a range limited according to the policy.

  For example, when the resident of the dwelling unit 11 where the dwelling unit 21 of interest is arranged does not go out, the wireless terminal 50 may be used only in the house. Therefore, the policy routing unit 33 selects a policy that uses the wireless LAN router 41 of the dwelling unit 1 in which the dwelling unit 21 is located as a notification range. On the other hand, when the resident goes out to the neighbor, the policy is selected so that the wireless LAN router 41 of the other house is included in the communication range, and when the resident uses the shared unit 12, the wireless LAN router of the shared unit 12 A policy can be selected to include 43 in the communication range.

Further, when the resident acts in the apartment house 10, it is possible to select a policy so that all wireless LAN routers 41 and 43 of the apartment house 10 are included in the communication range. When the resident of the dwelling unit 11 goes out of the apartment house 10, the wireless LAN access point 44 may be included in the communication range. In this case, the notification signal can be received by the wireless terminal 50 as long as communication with the wireless LAN access point 44 connected to the wide area network NT22 is possible.

  By the way, when the notification signal is transferred to the wireless terminal 50, in order to enable the wireless terminal 50 to respond to the notification signal, an application program for using the interphone system may be incorporated in the wireless terminal 50. is necessary. This application program is also used for receiving a notification signal.

  The wireless terminal 50 in which the application program is incorporated has the same function as the dwelling unit 21. That is, when the wireless terminal 50 receives the notification signal corresponding to the calling signal from the shared machine 23, the wireless terminal 50 displays a video image captured by the camera attached to the shared machine 23 on the display. At this time, a button area associated with a specific function is displayed on the screen of the wireless terminal 50. The function corresponding to the button area is equivalent to the function used when receiving a call signal in the dwelling unit 21, and for example, the button area corresponding to functions such as "call start", "call transfer", and "end" Is displayed on the display. The function of the button area is not limited, and the button area may be associated with another function.

  When the “call start” button area is operated, a call can be made with the shared machine 23 that has transmitted the call signal. If the state in which no audio signal is generated continues for a certain period of time after the “call start” button area is operated, the call is automatically ended. The call is also ended when the “end” button area is operated after the “call start” button area is operated. When the call is terminated, the display of the video imaged by the camera is automatically terminated.

  When the “communication start” button area is operated to enable a call, the protocol conversion unit 35 converts the protocol between the intercom system and the IP system. The protocol conversion unit 35 bi-directionally transmits audio information between the first I / F unit 31 and the second I / F unit 32, and transmits video information from the first I / F unit 31 to the second. The data is transmitted toward the I / F unit 32 of the. Note that the IP network transmits a packet containing audio data representing audio information and a packet containing video data representing video information. On the other hand, the signal for transmitting audio information and video information in the intercom system may be either an analog signal or a digital signal.

  When the button area of “call transfer” is operated, the other party who talks with the shared machine 23 is transferred to the management room master unit 24. This function is effective when trying to respond to an administrator with a visitor confirmed by an image captured by a camera attached to the shared machine 23. For example, when receiving a package from a delivery person, or Used when responding to a suspicious person.

  When the wireless terminal 50 has a pointing device such as a mouse, the button area operation means an operation of clicking a button over the button area, and when the wireless terminal 50 has a touch panel, This means an operation of touching the button area with a touch pen.

  By the way, depending on the performance of the wireless terminal 50, the communication quality of the IP network, and the amount of traffic, a sufficient band for transmitting video data for displaying video on the display unit and audio data for enabling a call is secured. You may not be able to. In preparation for such a case, the gateway device 30 preferably has a function of preferentially securing the information amount of audio data by suppressing the information amount of video data.

  The above-described operation example is an operation related to the calling signal, but the same operation is possible for an alarm signal generated by a fire detector or an intrusion sensor that is disposed in the dwelling unit 11 or the common unit 12 of the apartment house 10. It is. For the alarm signal, the wireless terminal 50 is also notified of the type of event that generated the alarm signal.

In the configuration example described above, the gateway device 30 is separated from the dwelling unit 21, but the function of the gateway device 30 may be built in the housing of the dwelling unit 21. In this case, it is desirable that the function of the gateway device 30 is provided as an adapter that is retrofitted into the dwelling unit 21. That is, when the interphone system is linked with the IP network, an adapter is attached to the dwell unit 21, and when it is not necessary to link the interphone system with the IP network, the dwell unit 21 can be used alone. In other words, depending on whether or not to attach the adapter without increasing the product varieties dwelling unit 21, it is possible to provide two types of dwelling unit 21.

  In the configuration example described above, the gateway device 30 is separated from the wireless LAN router 41, but the function of the wireless LAN router 41 may be built in the housing of the gateway device 30. Therefore, as described above, when the adapter having the function of the gateway device 30 is provided, the functions of the gateway device 30 and the wireless LAN router 41 are built in the housing of the dwelling unit 21, and the dwelling unit 11 has the dwelling unit 11. The function described above can be realized only by arranging 21.

Furthermore, as described above, the dwelling unit 21 has a function as an interphone master, and the gateway device 30 is connected to the interphone master. This relationship can be applied to various facilities and detached houses. For example, in the case of a detached house, it is possible to enjoy the above-described functions by combining the interphone master unit and the gateway device 30. become. Further, since there is no shared machine 23 in a detached house, the gateway device 30 transfers a notification signal to the wireless terminal 50 when the interphone master unit receives a call signal from the door phone slave unit. In this case, the radio terminal 50 can make a call with the door phone slave unit by an operation of “start call”. Note that, in the housing complex 10, a telephone call may be made between the door phone slave unit 22 and the wireless terminal 50.
