Connected to the trunk line 9.

  The room master unit 3 is configured as shown in the circuit block diagram of FIG. In FIG. 2, 11 is a demodulation circuit for demodulating the video signal, 12 is a monitor for outputting the transmitted video information, 13 is a call circuit for carrying out a call with the speaker 14 and the microphone 15, and 16 is a numeric keypad. 17 is a common camera button for displaying a captured image of the common camera, 18 is an operation means comprising a touch panel, 19a is a recording memory for recording video and images, and 19b stores various settings. A setting memory 21 for performing the operation, 21 is a parent device interface (parent device IF), and 22 is a parent device CPU for controlling the living room parent device 3.

  The dwelling unit adapter 7 is configured as shown in the circuit diagram of FIG. As shown in FIG. 3, the master trunk 9 provided from the controller 2 to each living room master 3 includes a data signal line 25a for transmitting a data signal, and call / video signal lines 25b and 25c for the collective entrance. (25b is the first channel, 25c is the second channel, and the call / video signal line is provided with two channels), and has a video signal line 25d used as a video communication path of the shared camera.

  The telephone / video signal lines 25b and 25c for the collective entrance machine and the video signal line 25d for the common camera are connected to the room parent via the first switch SW1, the second switch SW2, and the third switch SW3, respectively. It is connected to one call / video signal line 26 b provided in the machine 3. Reference numeral 26a denotes a master unit data signal line connected to the data signal transmission line 25a, and 26c denotes an adapter control signal line for controlling the dwelling unit adapter 7 from the living room master unit 3.

  Next, the operation of the apartment house intercom system configured as described above will be described. Since operations such as calling from the collective entrance 1, talking with residents, and unlocking the automatic door are the same as those in the prior art, the description thereof will be omitted. In addition, the captured images of the plurality of common-use cameras 5 are switched at predetermined time intervals under the control of the camera controller 6 and are output to the controller 2. This video is output from the camera controller 6 by NTSC, FM-modulated by the controller 2, and transmitted to each room base unit 3 through a dedicated video signal line 25d.

When the common unit camera button 17 of the living room main unit 3 is operated, a control signal is sent from the main unit CPU 22 to the dwelling unit adapter 7 via the main unit IF 21 and the adapter control signal line 26c. The third changeover switch SW3 is switched by the control signal to connect the video signal line 25d and the call / video signal line 26b, thereby forming a video communication path between the controller 2 and the room master unit 3. As a result, the video of the shared camera 5 being sent out is always displayed on the monitor 12 of the parent room 3. At that time, since the common area cameras 5 are sequentially switched as described above, the images of the respective common area cameras 5 are switched and displayed at predetermined time intervals in the living room master unit 3, and the resident Images can be confirmed sequentially.
In addition, since the video signal line 25d can be connected from each room base unit 3, a plurality of room base units 3 can simultaneously output the captured images of the shared section cameras.

  In this way, when the resident wants to carefully check the output image while outputting the captured image of the shared section camera 5, the master unit CPU 22 displays the image at that time by operating the operation means 18. The operation of stopping and displaying as a still image on the monitor 12 is performed. Further, this still image is automatically recorded in the recording memory 19a. Thereafter, the still image state is canceled by performing a predetermined operation, and the real-time video from the shared camera 5 is switched again. It should be noted that recording of still images in the recording memory 19a is not automatic, but may be performed by a predetermined operation, but security can be improved by automation.

  On the other hand, when a call is received from the collective entrance machine 1 while the video of the shared section camera 5 is being displayed, the following operation is performed. If there is a call from the collective entrance machine 1 while the video of the common use camera 5 is being displayed in the room master unit 3, a call signal is transmitted to the room base unit 3 via the controller 2, and the parent that detected the signal is transmitted. The machine CPU 22 further transmits a control signal to the dwelling unit adapter 7. Upon receipt of the control signal, the dwelling unit adapter 7 switches the third changeover switch SW3 to disconnect the video signal line 25d, and switches the first changeover switch SW1 to communicate between the collective entrance 1 and the room master unit 3. A video communication line is formed by connecting video signal lines. Thereby, the resident can instantly confirm the video of the visitor in front of the collective entrance 1.

  After the resident confirms the visitor, a call can be performed by a predetermined operation, and when the end call operation is performed (or when the call is finished without entering the call), the control of the room master unit 3 is performed. Thus, the first changeover switch SW1 and the third changeover switch SW3 are switched, and the video of the shared camera 5 is switched again.

In this way, since the video communication path of the common-use camera is always secured, it is convenient that the video of the common-use camera can be displayed at any time with any living room parent machine, and at the same time, multiple residents can share the common-use camera. Camera images can be viewed, improving security.
In addition, even if there are multiple cameras in the common area, individual captured images can be checked in sequence without any special operation, security can be further improved, and the video of the common area cameras can be switched automatically. However, if there is a screen that the resident wants to confirm, it can be confirmed as a still image, which improves convenience.
Furthermore, even if the video of the common area camera is being checked, if a call is made at the central entrance, the video of the common area camera is automatically switched to the video of the central entrance, so the resident can perform a switching operation. Visitors can be confirmed without doing so, improving operability.
In addition, the convenience of the camera can be improved because the video of the shared camera can be automatically viewed again after the call with the collective entrance machine is terminated.

Here, the first selector switch SW1 is operated to connect the collective entrance machine 1 and the living room base unit 3 by the first channel 25b. However, when the first channel 25b is in use, the second switch The collective entrance machine 1 and the living room base unit 3 are connected by operating the switch SW2 and using the second channel 25c.
In addition, the timing of switching is linked by detecting the call signal, but when the call signal is received, the video of the common-use camera is maintained, and after receiving an operation of pressing the call button for calling with a visitor, The image video may be switched from the common use camera to the visitor video of the entrance hall. In this case, the master unit CPU 22 detects an operation of pressing a call button or the like, transmits a control signal to the dwelling unit adapter 7 and receives the signal, and the dwelling unit adapter 7 cuts off the video path formed with the common unit camera 5. It ’s fine. By doing so, the video of the common entrance camera can be displayed with priority, without suddenly switching to the video of the entrance hall, and convenience can be improved.

Next, a second embodiment of an apartment house intercom system will be described. The first embodiment is different from the first embodiment in that it does not have a dedicated line for the video signal of the common use camera, and the video signal from the collective entrance machine 1 and the video from the common use camera 6 are common. It is the composition transmitted via.
In this case, the dwelling unit adapter 7 is configured as shown in FIG. 4, and the connection to the controller 2 is connected by a three-wire signal line in the same manner as the connection to the living room base unit 3. In addition, the same code | symbol is provided to the component similar to the said FIG. 3, and description is abbreviate | omitted. In this case, the controller 2 is configured as shown in FIG. 5, 30 and 31 are data interfaces (data IF), 32 is a video path switching unit for selecting a video signal to be sent to the room master unit 3, and 33 is 2 A channel switching unit 34 for switching the communication / video signal lines 25b and 25c having a channel indicates a controller CPU.

  In the apartment house intercom system configured as described above, the image taken by the common room camera is displayed in the room master unit as follows. When the shared camera button 17 of the living room base unit 3 is operated, a control signal is transmitted to the control unit 2 via the dwelling unit adapter 7. Here, the control unit CPU 34 confirms the status of the vacant channel. For example, when the first channel 25b is used for a call with another room master unit 3 and the collective entrance unit 1, it is an vacant channel. The second channel 25c is controlled to be used.

  Thus, for example, the second channel 25c is used by the channel switching unit 33, and the shared camera 5 switched by the video path switching unit 32 is connected to the second channel 25c. Further, the controller CPU 34 transmits the use of the second channel 25c as a data signal to the living room parent unit 3, and the living room parent unit 3 transmits a control signal to the dwelling unit adapter 7 and switches the second changeover switch SW2. The second channel 25c and the call / video signal line 26b are connected. In this way, the video of the shared camera 5 is displayed on the monitor 12 of the living room master unit 3.

In this case, the control operation of the shared unit camera by the controller 2 will be described. Upon receiving the operation of the shared unit camera button 17 of the living room parent unit 3, the ID information of the living room parent unit 3 is stored in the controller 2, and this In response to the operation, the camera controller 6 starts imaging of the common use camera 5 and transmits the captured image to the controller 2. When the image output in the room master unit 3 is completed, the stored ID information is erased and the video from the common use camera 5 is disabled, and the camera controller 6 stops the transmission of the video signal, and the substantial common use unit The camera 5 is disconnected from the system.
In addition, when a plurality of living room master units 3 are outputting captured images of the shared section camera 5, a plurality of ID information of the living room parent unit 3 is stored in the control unit 2, and all the ID information is deleted. At the time, that is, when the image output from all the room base units 3 is completed, the transmission of the video signal from the shared camera 5 is stopped. Note that during the imaging operation, as in the above-described embodiment, each shared camera 5 is switched at predetermined time intervals to transmit a video signal.

  In this way, it is possible to output the video of the common-use camera in any room base unit using an empty channel without providing a dedicated video signal line. And when the video of the common-use camera is not required, since the output of the picked-up video of the common-use camera is stopped and only the video from the collective entrance is transmitted, it is easy to control to switch the video signal line.

Also in the second embodiment, when there is a call from the collective entrance machine 1, it is possible to switch to the video of the collective entrance machine as in the first embodiment. Channel (for example, the first channel 25b) is used. In this case, there is no problem because the CH2 connection is maintained as it is when another room master unit 3 is outputting the video of the shared camera 5.
In each of the above embodiments, the number of channels that can transmit a call / video signal is two, but the present invention is not limited to this. Furthermore, the dwelling unit adapter 7 may be built in the living room base unit 3, and the camera controller 6 may be configured integrally with the control unit 2.
