  The communication unit 35 of the television device 30 is a communication interface for receiving a video signal from the indoor intercom device 20. For example, the indoor intercom device 20 and the television device 30 are connected by a wireless LAN, a wired LAN, and an HDMI (registered trademark) cable. Also, PLC (Power Line Communication) may be used. When a wireless LAN router is installed in the room and the television device 30 is already wirelessly connected to the router, the indoor interphone device 20 and the television device 30 are wirelessly connected by wirelessly connecting the indoor interphone device 20 to the router. Can connect.

  The display unit 38 reproduces the video signal supplied from the control unit 34 and displays an image. The speaker 33 reproduces the sound signal supplied from the control unit 34 and outputs the sound. The infrared light receiving unit 36 receives an infrared signal from the remote control device 37 and outputs it to the control unit 34.

  The control unit 24 of the indoor intercom device 20 performs bidirectional communication of control signals with the television device 30 via the indoor communication unit 25b. For example, a power control signal for the television device 30 can be transmitted and received as the control signal. When the television apparatus 30 is a model equipped with a browser function, transmission / reception of control signals is controlled by the browser. In the case of a model not equipped with a browser function, an adapter device that controls transmission / reception of control signals to / from the indoor intercom device 20 may be externally attached. In the following description, a television device 30 equipped with a browser function is assumed. Note that the control signal may be communicated on a different channel from the video signal. For example, the control signal may be transmitted by infrared communication.

  The control unit 24 of the indoor intercom device 20 periodically acquires the power state of the television device 30 from the control unit 34 of the television device 30. The power state includes an on state and an off state. Some models have a standby state.

  When the control unit 24 of the indoor intercom device 20 receives a call signal from the lobby intercom device 10 via the outdoor communication unit 25a, when the power of the television device 30 is off or in a standby state, the control unit 24 performs the television via the indoor communication unit 25b. A control signal for instructing power-on is transmitted to the device 30.

  The resident hears the ringing sound output from the speaker 23b of the indoor intercom device 20 and determines whether or not to respond by watching the video of the visitor displayed on the television device 30. When responding, a call (receiving) button provided on the operation unit 22 of the indoor intercom device 20 is pressed to start the call. When inviting visitors to the dwelling unit, press the unlock button to unlock.

  In order to take the above measures, the resident needs to go to the place where the indoor intercom device 20 is installed. When watching the television apparatus 30 in the living room, it is more convenient to be able to handle it while in the living room. Hereinafter, a method for enabling a response to a call in a room where the television apparatus 30 is installed will be described. First, an application program that allows the remote control device 37 to respond to a call is installed in the television device 30.

  When receiving the call signal from the indoor intercom device 20, the control unit 34 of the television device 30 causes the display unit 38 to display a call button icon and an unlock button icon. The resident can operate the remote control device 37 to perform a call start operation. Unlocking operation can also be performed. If no response is made, an operation for erasing the video of the visitor displayed on the display unit 38 can also be performed. When the control unit 34 receives a call start operation signal or an unlocking operation signal from the remote control device 37 via the infrared light receiving unit 36, the control unit 34 transmits a control signal based on the operation signal to the indoor intercom device 20. When the control signal instructing the start of the call is received from the television device 30, the control unit 24 of the indoor intercom device 20 establishes a call channel between the lobby intercom device 10 and the indoor intercom device 20. The resident then calls hands-free with a visitor in the lobby.

  Moreover, in order to eliminate the need to go to the place where the indoor intercom device 20 is installed, a resident may be able to operate the indoor intercom device 20 by voice recognition. When the control unit 24 of the indoor intercom device 20 receives a call signal from the lobby intercom device 10, the control unit 24 transitions to the voice recognition mode. In this state, when the resident speaks, the microphone 23 a acquires the sound and outputs it to the control unit 24. When the control unit 24 compares the voice data acquired by the microphone 23a with voice data registered in advance (for example, voice data of a phrase such as “Yes” or “please open”) and there is matching voice data The operation associated with the voice data is executed.

  FIG. 3 is a flowchart showing an example of processing from calling to starting a call in the intercom system 1 according to the embodiment of the present invention. When a visitor presses the call button of the lobby intercom device 10 in the lobby (Y in S10), a call signal is transmitted to the indoor intercom device 20. The control unit 24 of the indoor intercom device 20 checks the power supply state of the television device 30 (S11). When the power is off or in the standby state (N in S11), the control unit 24 transmits a control signal for instructing the television device 30 to turn on the power (S12).

  When the television device 30 is turned on (Y in S11) or after the television device 30 is turned on in response to the control signal, the control unit 24 of the indoor intercom device 20 is transmitted from the lobby intercom device 10. The video signal of the visitor is transferred to the television device 30 (S13). The control unit 24 of the indoor intercom device 20 transfers a video signal and transmits a control signal that causes the television device 30 to output a ringing tone from the speaker 33 (S14).

  This control signal does not send the sound data of the ringing tone but is a reproduction instruction signal of the sound data of the ringing tone held in the television apparatus 30 in advance. Note that both the ringing tone output from the television device 30 and the ringing tone output from the indoor intercom device 20 may be performed, or either one may be performed.

  The controller 24 of the indoor intercom apparatus 20 waits for a call start operation (S18) until the set period elapses after the ringing sound is heard (N in S15). When the set period elapses without a call start operation (Y in S15, N in S18), the control unit 24 confirms whether or not the power of the television device 30 is turned on by invoking the process of step S12 ( S16). When the process of step S12 has been activated (Y of S16), the control unit 24 transmits a control signal for instructing the television device 30 to turn off or stand by (S17). Since the resident is away or is not watching the television device 30, it is better to turn off the television device 30 or set the television device 30 to the standby state after the set period has elapsed. On the other hand, when the process of step S12 is not activated (N of S16), the process of step S17 is skipped. This is a case where the resident is watching the television device 30 but does not respond intentionally, and it is better not to automatically turn off the power of the television device 30 or set it to standby.

  When a call start operation is performed (Y in S18) before the set period elapses after the ringing sound is sounded (Y in S18), the control unit 24 of the indoor intercom device 20 communicates with the lobby intercom device 10 through the communication channel. Is established (S19).

  In the description so far, it is assumed that one television device 30 is installed in the dwelling unit. However, a plurality of television devices 30 may be installed in the dwelling unit.

  FIG. 4 is a block diagram for explaining an example when a plurality of television devices 30 are installed in a dwelling unit. FIG. 4 illustrates an example in which the first television apparatus 30a and the second television apparatus 30b are installed in the room A, the third television apparatus 30c is installed in the room B, and the fourth television apparatus 30d is installed in the room D. Yes.

  A television device 30 that transmits a video signal of a visitor is registered in advance in the control unit 24 of the indoor intercom device 20. Normally, all the television devices 30 installed in the dwelling unit are registered so that a resident in any room can check the face of the visitor. In addition, it is possible to register a specific television device 30 that transmits a video signal after the call starts. Usually, the television device 30 installed at a position closest to the position where the indoor intercom device 20 is installed is registered. In the example illustrated in FIG. 4, the first television device 30 a installed at the position closest to the indoor intercom device 20 is registered.

  In addition, the television device 30 that receives a call start instruction or an unlocking operation instruction can be registered. Other television devices 30 can display images, but operations such as the start of a call from the remote control device 37 are invalid. That is, the control unit 24 of the indoor intercom device 20 validates the call start operation signal or the unlock operation signal from the registered television device 30 among the plurality of television devices 30 in the dwelling unit, and is not registered. The call start operation signal or the unlock operation signal from 30 is invalidated. In this case, it is possible to prevent a call start operation from being performed with the remote control device 37 attached to the television device 30 installed in a room where the voice cannot reach the microphone 23a. When a call start operation is performed with the remote control device 37, it is necessary to move to a position where a hands-free call is possible.

  The control unit 24 of the indoor intercom device 20 transmits the video signal acquired from the lobby intercom device 10 to all the registered television devices 30 via the indoor communication unit 25b. When the call start operation is started, the video signal is transmitted to one registered television device 30 and the transmission of the video signal to the other television device 30 is invalidated. This processing example assumes a case where one television apparatus 30 that transmits a video signal after the start of a call is registered. It is also possible to register a plurality of television devices 30 that transmit video signals after the start of a call. Note that when a video signal is transmitted through a wireless LAN, a control signal is transmitted to instruct the other television apparatus 30 not to receive the video signal.

  Further, when the control unit 24 receives a call start operation signal from any of the television devices 30, the control unit 24 transmits the video signal to the television device 30 and invalidates the transmission of the video signal to the other television device 30. This processing example assumes a case where one television device 30 that transmits a video signal after the start of a call is not registered. That is, it is assumed that a plurality of television devices 30 can perform a call start operation. In any case, it can be estimated that the resident who performed the call start operation is watching the visitor's video on the TV device 30 paired with the remote control device 37 on which the operation is performed. Therefore, it can be determined that the video transmission to the other television device 30 is unnecessary, and thus the video transmission to the other television device 30 is ended after the call start operation is performed.

  In the description so far, it is assumed that the resident uses the transmitter / receiver 23 of the indoor intercom device 20 to make a hands-free call. However, when the indoor interphone device 20 and the resident are far apart, Sometimes it does not reach. For example, a typical example is a case where the entrance where the indoor intercom device 20 is installed and the living room where the television device 30 is installed are separated from each other. As a countermeasure, a hands-free terminal device 40 independent of the indoor intercom device 20 is installed on a wall of a room where the television device 30 is installed.

  FIG. 5 is a diagram showing a configuration of the intercom system 1 (including the hands-free terminal device 40) according to the embodiment of the present invention. The intercom system 1 shown in FIG. 5 has a configuration in which a hands-free terminal device 40 is added to the intercom system 1 shown in FIG. The hands-free terminal device 40 includes a highly sensitive microphone and speaker. The hands-free terminal device 40 is connected to the indoor intercom device 20 by wire or wirelessly. The hands-free terminal device 40 is not equipped with a receiver and a monitor, unlike a slave unit for an interphone master unit. It is a small device that can be embedded in a wall. In the present embodiment, it is assumed that the television device 30 is installed by being embedded in the wall of the room in which the television device 30 is installed.

  The control unit 24 of the indoor intercom device 20 transmits the audio signal acquired from the lobby intercom device 10 to the hands-free terminal device 40 installed in the room, and the audio signal acquired from the hands-free terminal device 40 is sent to the lobby intercom device 10. Send. The transmitter / receiver 23 mounted on the main body of the indoor intercom device 20 and the hands-free terminal device 40 can be used properly depending on the place where the call start operation is performed.

  When a call button installed on the operation unit 22 of the indoor intercom device 20 is pressed, the control unit 24 enables the transmission / reception unit 23 mounted on the main body of the indoor interphone device 20 and disables the hands-free terminal device 40. . On the other hand, when a call start operation is performed on the remote control device 37 of the television device 30, the control unit 24 invalidates the transmission / reception unit 23 mounted on the main body of the indoor intercom device 20 and validates the hands-free terminal device 40. .

  It is also possible to design the indoor intercom device 20 without the transmission / reception unit 23. In this case, the call button and the unlock button can be omitted. Since the monitor, microphone, speaker, call button, and unlock button are not installed, the indoor intercom device 20 can be greatly reduced in size. Further, the indoor intercom device 20 itself may be installed on the wall of the room where the television device 30 is installed without providing the hands-free terminal device 40.

  In the above description, the process between the lobby intercom apparatus 10 and the indoor intercom apparatus 20 has been described, but the process between the door intercom apparatus 50 and the indoor intercom apparatus 20 can be similarly performed. Even if the intercom system 1 is installed in an apartment house, the lobby intercom device 10 may not be provided in a small apartment or apartment. On the other hand, depending on the construction of the apartment, the door intercom device 50 may not be provided.

  In the above description, the intercom system 1 installed in a condominium has been described. However, the same can be applied to the intercom system 1 installed in a detached house. In the intercom system 1 installed in a detached house, the lobby intercom device 10 and the control device 60 are not provided. All the processes in the above description are performed between the door intercom device 50 and the indoor intercom device 20.

  As described above, according to the present embodiment, since the monitor is not mounted on the indoor intercom device 20, it can be reduced in size and can be made inconspicuous. Since the monitor is not mounted, the entire indoor intercom device 20 can be colored in any color, and the interior can be unified. Moreover, the cost can be reduced by not mounting a monitor. Even if a monitor is not installed, if an alarm lamp (for example, an LED lamp) is installed, it is possible to pass the certification prescribed by the Fire Department.

  In addition, television is the most popular among electronic devices, and existing devices can be used effectively. An intercom handset as a dedicated device is not required. Also, since the TV has a larger screen than PCs and tablets, it is easy to check the video of visitors. In addition, the remote control operation of the TV is less resistant to the elderly and is easily accepted by the elderly.

  The present invention has been described based on the embodiments. The embodiments are exemplifications, and it will be understood by those skilled in the art that various modifications can be made to combinations of the respective constituent elements and processing processes, and such modifications are within the scope of the present invention. .

  For example, when the indoor intercom device 20 and the television device 30 are not connected, the control unit 24 of the indoor intercom device 20 may notify the resident that the television device 30 is not connected. For example, the LED lamp is turned on or a message is transmitted from the speaker 23b. Accordingly, it is possible to prevent the state where the connection between the indoor intercom device 20 and the television device 30 is released without the resident being aware.

  Further, when the television device 30 is not connected to the indoor intercom device 20, the control unit 24 does not transfer the video signal acquired from the lobby intercom device 10 to the television device 30. Thereby, the power consumption of the indoor communication part 25b can be reduced. In particular, when wireless is used, the power saving effect is increased.

  When the television device 30 is not connected to the indoor intercom device 20, the control unit 24 does not output a ringing tone from the speaker 23b. If the video of the visitor cannot be confirmed, a setting that does not respond to the visitor can be made.

  When the television device 30 is not connected to the indoor intercom device 20, the control unit 24 instructs the lobby intercom device 10 to send a fixed message such as “Please wait for a while” from the speaker 13b. In this case, visitors can wait until the television device 30 is connected to the indoor intercom device 20.

  When the television device 30 is not connected to the indoor intercom device 20, the control unit 24 transmits information indicating that the television device 30 is not connected to the control device 60. The control device 60 does not relay the video signal acquired from the lobby intercom device 10 to the indoor intercom device 20 when the television device 30 is not connected to the indoor intercom device 20. Audio signals are relayed as usual. Thereby, the traffic amount of the trunk line which connects the control apparatus 60 and the indoor intercom apparatus 20 can be reduced.

  Further, when the resolution of the imaging unit 11 of the lobby intercom device 10 and the resolution of the display unit 38 of the television device 30 are different, the control unit 24 converts the resolution of the video signal acquired from the lobby intercom device 10 into the resolution of the display unit 38. To the television set 30. By transmitting video corresponding to the monitor size to the television device 30, it is possible to suppress the occurrence of display defects such as screen displacement.

  The indoor intercom device 20 may include a recording medium (for example, SSD, HDD) for recording a video signal acquired from the lobby intercom device 10 when a resident is absent. When a reproduction instruction operation is performed after the resident returns home, the control unit 24 reads a video signal from the recording medium and transfers it to the television apparatus 30. As a result, the resident can check the video of the visitor at the time of absence.

  In the above description, the example in which the indoor intercom device 20 uses the television device 30 as a transfer destination for transferring the video signal acquired from the lobby intercom device 10 has been described. In this regard, the video display device is not limited to the television device 30 as long as the video display device includes a display capable of displaying video. A PC (which may be a desktop type or a notebook type), a tablet, a smartphone, a portable game machine, or a portable music player can be used as a transfer destination video display device. Further, a projection-type video display device such as a projector can be used as the transfer destination video display device. When a wall or the like is used as the projection surface, the projection space can be used as a normal wall in a state where the projection-type image display device is not used, so that the indoor space can be used effectively. Various types of video display devices can be registered in the indoor intercom device 20 as transfer destinations. For example, a living room can be registered as a television device, a study can be registered as a PC, and a children's room can be registered as a portable game machine.
