Includes a call button 55 for answering a call, a microphone 56 for making a call, a speaker 57, and the like.

The safety confirmation system configured as described above operates as follows. The illuminating devices 1 and 3 transmit an illuminance change signal each time the remote control 2 or 4 receives a lighting / extinguishing operation or an illuminance changing operation or every time an illuminating switch receives an on / off operation.
Specifically, when the resident operates to turn on / off the first lighting device 1 or change the illuminance by the first remote controller 2, the remote control signal receiving unit 20 of the first lighting device 1 is transmitted from the first remote controller 2. Receive radio signals. Upon receiving this signal, the illumination control unit 25 controls the illumination light emitting unit 21 to turn on / off or change the illuminance. At the same time, a state change signal is transmitted from the wireless transmission unit 22. The transmission of the state change signal is the same when an on / off operation is received by a lighting switch. When the on / off operation is received, an on / off operation signal is sent from the power on / off detection unit 23 to the lighting control unit 25. The illumination control unit 25 transmits a state change signal from the wireless transmission unit 22. This operation is the same when the second lighting device 3 is operated.

The illumination light emitting unit 21 is turned on / off by this on / off operation. When the power is turned off, the power supplied to all the circuits is naturally stopped. However, the power supply unit 24 includes a storage capacitor (not shown), and the illumination control unit 25 and the wireless transmission unit 22 are 1 second. The operation can be continued to some extent. Therefore, a state change signal is generated and transmitted during that time.
Further, although the lighting operation is performed by the operation using the remote controls 2 and 4 and the lighting switch, the operation may be performed only by the lighting switch without the remote control. Furthermore, although the illuminance changing operation is detected in addition to the on / off state, only the on operation or only the off operation may be detected to transmit the state change signal.

Thus, the state change signal transmitted from the lighting devices 1 and 3 is received by the signal receiving unit 33 of the lighting operation detector 5. The first timer of the lighting operation detector 5 always counts for a predetermined time (for example, 12 hours), and the detector control unit 35 is reset every time a state change signal is received, and the count for 12 hours is restarted. Start it.
When the time during which no state change signal is received continues for 12 hours, the first timer 30 counts up. Upon receiving this count-up, the detector control unit 35 makes an announcement from the speaker 32 such as “I will notify you of an abnormal alarm soon” and reports that an alarm notification will be issued soon. At the same time, for example, the second timer 31 for counting 5 minutes is started.

  The announcement sound is stored in the detector control unit 35 in advance. The count times of the first timer 30 and the second timer 31 are arbitrary. For example, the count time of the first timer 30 may be 20 hours, and the count time of the second timer 31 may be 1 minute.

  If the resident is aware of this announcement and no abnormality has occurred (no abnormality has occurred in the resident himself), the first illuminating device 1 or the resident by the resident before the second timer 31 counts up. Lighting operations such as turning on / off the second lighting device 3 are performed. Then, a state change signal is transmitted from the operated lighting devices 1 and 3, and the lighting operation detector 5 receives it. Upon receiving this state change signal, the detector control unit 35 ends the announcement and resets the second timer 31. And the count of the 1st timer 30 is started, and the report to the outside is not performed.

On the other hand, if the resident is in a situation where the announcement cannot be made even when the announcement is started, or if the announcement cannot be recognized due to unconsciousness or the like, the second timer 31 is operated without operating the lighting devices 1 and 3. Will be counted up. In response to this count-up, the detector control unit 35 transmits an abnormality occurrence signal to the room master unit 7 via the detector IF 34. The room base unit 7 that has received this abnormality occurrence signal at the base unit first IF 45 refers to the external report destination stored in the external report memory 42 and creates and sends an e-mail to the mobile phone 13 or the like. In addition, the parent device control unit 46 activates the first indoor camera 10 and the second indoor camera 11 connected to the living room parent device 7 and records the captured image in the recording memory 43.
Note that the URL information of the recording memory 43 storing the video may be attached to the email transmitted at this time, or the video data itself may be attached.

  The occurrence of an abnormality can be confirmed from a distance by checking the mobile phone 13 that has received this e-mail by the family of the report destination. When the URL information of the video is attached, the room condition can be confirmed by the video. Based on this information, the reporter's family or the like can make a quick response such as calling the resident of the abnormality signal transmission source or arranging an ambulance.

  In addition, alarm notification is performed by a message or the like from the speaker of the communication unit 41, and further, alarm control is performed for the entrance slave unit 6 and the extension master unit 8. In this way, the alarm notification is also performed from the speaker 54 of the entrance unit 6 and the speaker 57 of the extension base unit 8.

  The above operation is based on the assumption that the resident is at home. However, when the resident is absent for a long time due to travel or the like, the first timer 30 is counted up by operating the absence setting button 12. However, the notification of the occurrence of abnormality is stopped. Specifically, when the absence setting button 12 is operated, an absence signal is transmitted to the living room master unit 7. The parent device control unit 46 that has received this absence signal shifts to the absence setting mode, and even if the abnormality occurrence signal is received from the lighting operation detector 5, the parent device control unit 46 ignores this signal and notifies the abnormality occurrence. Do not implement. Also, the indoor cameras 10 and 11 are not activated. This absence setting mode is canceled by a predetermined operation of the room master unit 7 when the user returns home.

  The connection destination of the absence setting button 12 may be the lighting operation detector 5 instead of the living room master unit 7. In this case, the detector control unit 35 that has received the absence setting signal does not transmit the abnormality occurrence signal to the room master unit 7 even if the first timer 30 counts up. Thereby, the living room base unit 7 does not carry out notification of the occurrence of an abnormality.

In this way, the resident can detect the occurrence of an abnormality based on a change in the state of lighting devices 1 and 3 that are always used for living, so that the resident does not need to operate it consciously. Abnormality can be detected with high accuracy. Then, by using the living room master unit 7 of the intercom device provided with the external communication function, it is not necessary to install a new external notification device, and the system can be constructed at a low cost.
Further, since the occurrence of an abnormality is also notified from the entrance cordless handset 6, neighboring residents and passersby can recognize the occurrence of the abnormality in the dwelling unit, and a quick response is possible. In addition, even if the resident happens to use the lighting devices 1 and 3 for a while, the notification is made to the resident to confirm the malfunction before notifying the outside of the occurrence of the abnormality. be able to. Then, since an alarm is sounded by the room master unit 7 in response to the occurrence of an abnormality, the resident can also recognize that notification has been given to the outside.
Further, since an alarm is also issued from the extension base unit 8, if there is a living person, the alarm can be recognized and immediately rushed. For example, if the extension master 8 is installed in a room with lighting that does not function the lighting operation detector 5 and there is a living person in the room, an abnormality in the lighting operated by the living person is not detected. Recognize the occurrence of abnormalities and rush immediately.
Furthermore, URL information or video data for acquiring video data is attached when an imaging signal is recorded by interlocking the indoor cameras 10 and 11 in response to an abnormality occurrence signal and notified to the external mobile phone 13. The reporter can check the situation by video, making it easier to grasp the situation.
In addition, by providing the absence setting button 12, even if the first timer 30 counts up due to the absence, the notification operation is not performed, so that erroneous notification can be prevented and the burden for confirming safety to the notification destination can be reduced.

In addition, in the said embodiment, although the 2nd timer 31 is provided in the lighting operation detector 5, you may provide in the living room main | base station 7. FIG. In the case where the room master unit 7 is provided, when the room base unit 7 receives an abnormality occurrence signal of the lighting operation detector 5, the base unit control unit 46 starts the second timer 31 without performing the alarm issuing operation. Until the time is up, the above-mentioned announcement may be reported from the calling unit 41 of the living room base unit 7. In this case, the announcement voice is stored in base unit control unit 46. Then, if the room master unit 7 receives a predetermined stop operation during the announcement, the reset operation is performed to stop the announcement, and thereafter, the notification of the occurrence of the abnormality may not be performed, so that false alarms can be prevented. Can do. On the other hand, when the second timer 31 counts up without being stopped, an abnormality occurrence notification may be sent.
Further, the second timer is not provided in any of the lighting operation detector 5 and the living room base unit 7 and may be omitted. That is, there is no need to make an announcement before issuing an alarm.
Furthermore, although the lighting operation detector 5 and the living room base unit 7 are configured as separate bodies, they may be configured as a single unit, which makes it easy to control and reduces manufacturing costs. it can.
