  Specifically, when the human sensor 110 does not detect the presence of the target person in the room, the switch control unit 510 and the microphone 120 output the voice (the target person's voice, snoring, body motion sound, physical sound, etc.). When the predetermined time is not acquired (that is, when indicated by a cross in FIG. 9), the speaker 130 and the like are turned off. Specifically, the switch control unit 510 determines whether the target person is absent in the room for a predetermined period of time (current and a period that is a predetermined period after the current period) based on the audio information stored in the audio information storage unit 320. Determine whether or not. Then, the switch control unit 510 turns off the speaker 130 and the like when the human sensor 110 does not detect the presence of the target person in the room and when the microphone 120 does not acquire sound for a predetermined time.

  In addition, the switch control unit 510 acquires the voice (speech voice, snoring, body motion sound, physical sound, etc.) for a predetermined time when the human sensor 110 detects that the target person is present in the room or the microphone 120 When this occurs (that is, in the case indicated by ◎ and ○ in FIG. 9), the speaker 130 and the like are turned on (keep on).

  Thus, since it is determined by both the human sensor 110 and the microphone 120 whether there is a subject in the room, the accuracy of the determination can be improved. Accordingly, it is possible to prevent the speaker 130 and the like from being turned off accidentally when the target person is actually in the room.

As described above, in another example of the fourth embodiment, when the human sensor 110 does not detect that there is a subject in the room, the power management unit 500 does not input sound into the microphone 120 for a predetermined time. Sometimes, the speaker 130 is turned off.
With this configuration, energy saving can be achieved.

  As mentioned above, although the example of 4th embodiment of this invention was demonstrated, this invention is not limited to the said structure, A various change is possible within the range of the invention described in the claim. .

  For example, the switch control unit 510 is a speaker only when the human sensor 110 detects that there is a subject in the room and when the microphone 120 has acquired sound for a predetermined time (indicated by ◎ in FIG. 9). 130 or the like may be turned on (leave on).

  Further, the device unit 100 includes a triaxial acceleration sensor as a human detection unit, and determines whether or not there is a target person based on information (such as movement of a person, behavior, vibration due to operation of a device, etc.) of the triaxial acceleration sensor. It may be.

  In addition, HEMS (Home Energy Management System) is used as a human detection unit, and it is determined whether or not there is a target person based on HEMS power information (power consumption of home appliances). When the absence is determined, the speaker 130 of the device unit 100 is turned off. You may do.

  In addition, an electric key is used as a human detection unit, and it is determined from the information (unlocked / locked) of the electric key whether someone is in the building / nobody is present, and when the absence is determined, the speaker 130 of the device unit 100 is turned off. It may be a thing.

  Further, the condition for the switch control unit 510 to turn off the speaker 130 and the like is not limited to this. For example, the switch control unit 510 may turn off the speaker 130 or the like at a time when the target person is expected to be absent from the room (presence of absence).

  Specifically, the analysis unit 410 analyzes the human detection information stored in the human detection information storage unit 310, and statistically analyzes the data on the presence / absence of the target person in the room in time series, thereby predicting the absence time in the room. (Time) is calculated.

  For example, as shown in FIG. 10, for each room of a living room, a dining room, a kitchen, and a bedroom, based on the person detection information stored in the person detection information storage unit 310, the time at which the probability of staying in the room is a predetermined value or more. (Time indicated by a rectangle in the graph shown in FIG. 10) is the expected occupancy time, and a time when the probability of occupancy is less than a predetermined value (time other than the time indicated by the rectangle in the graph shown in FIG. 10) And

  The switch control unit 510 refers to the estimated absence time calculated by the analysis unit 410 and turns off the speaker 130 and the like during the estimated absence time. In addition, when the presence sensor 110 (and the microphone 120) detects that there is a person in the room during the expected absence time, the detection result is prioritized and the speaker 130 and the like are turned back on.

  Thus, on / off of the speaker 130 and the like can be controlled using the data stored in the human detection information storage unit 310. Thereby, the standby power of the speaker 130 or the like can be reduced, and as a result, energy saving can be achieved.

As described above, the interface unit 4 according to another example of the fourth embodiment includes the data collection unit 300 (data storage unit) that stores data of the detection result of the human sensor 110, and includes the data analysis unit 400, The power management unit 500 (control unit) calculates an expected absence time of the subject based on the data stored in the human detection information storage unit 310, and turns off the speaker 130 during the estimated absence time. To do.
With this configuration, energy saving can be achieved.
