  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described with reference to the drawings. FIG. 1 is a configuration diagram illustrating a noise detection system according to the present embodiment.

  As shown in FIG. 1, the noise detection system 1 is installed in an apartment house, a hotel, or the like, and when noise generated in its own living space (first living space) is felt noisy to a neighbor. When it is predicted, it notifies the self. The noise detection system 1 includes a microphone 10, a vibration detector 20, a display unit (notification unit) 30, a component 40, a weight sensor 50, a home information breaker (setting unit) 60, and a building control device 70. In the present embodiment, the noise detection system 1 also functions as a network environment facility, so the Internet line 90 and the center server 100 are also illustrated.

  The microphone 10 outputs an electrical signal corresponding to the volume generated in the first living space, and transmits the electrical signal corresponding to the volume to the building control device 70 through the home information breaker 60. The vibration detector 20 outputs an electric signal corresponding to the vibration amount generated in the first living space, and transmits an electric signal corresponding to the vibration amount to the building control device 70 through the home information breaker 60. is there.

  The display unit 30 is a video display device such as NetTV. In addition, the display unit 30 transmits information on whether the power is turned on and information on the sound volume when the power is turned on to the building control device 70 through the home information breaker 60. The component 40 is a playback device such as music. In addition, the component 40 transmits information on whether or not the power is turned on and information on the sound volume when the power is turned on to the building control device 70 through the home information breaker 60.

  The weight sensor 50 is installed on a bed in a bedroom, a sofa in a living room, etc., and detects the weight when a resident is sleeping on the bed or sitting on the sofa, and informs that information to the home information breaker. 60 to the building control device 70. In the following, a resident is not limited to a person who lives in a house for a long period of time, but includes a person who temporarily stays at a hotel or the like.

  The home information breaker 60 functions as a blocking device that blocks unnecessary information transmitted from the Internet line 90 side. In the present embodiment, the home information breaker 60 also functions as a relay device that relays between the building control device 70 and the microphone 10 or the like.

  FIG. 2 is a functional block diagram showing details of the building control device 70 shown in FIG. FIG. 3 is a diagram illustrating an example of an apartment house in which the noise detection system 1 is installed, in which (a) shows an appearance and (b) shows an adjacency relationship.

  As shown in FIG. 2, the building control device 70 includes a measurement unit (measurement unit) 71, a storage unit (storage unit) 72, and a comparison unit (comparison unit) 73.

  The measurement unit 71 measures the volume level generated in the first living space based on the electrical signal from the microphone 10 and the electrical signal from the vibration detector 20. Moreover, the measurement part 71 measures the volume level generate | occur | produced in a 1st living space based on the electric signal from the microphone 10 and the vibration detector 20 which are installed in the 1st living space.

  The memory | storage part 72 memorize | stores the desired threshold value set in the 2nd living space adjacent to the 1st living space. This desired threshold is set and stored for each second living space, but in reality, as shown in FIG. 3A, noise detection according to the present embodiment is applied to a 10-story apartment house with 5 rooms on each floor. When the system 1 is applied, the desired threshold is set for each of 50 living spaces of 50 rooms × 10 floors. That is, as shown in FIG. 3B, the living spaces A to D adjacent to the own living space (the first living space X) are the second living spaces, but from the second living spaces AD. This is because it can be said that the own living space X is the second living space.

  Here, the desired threshold will be further described. FIG. 4 is a diagram illustrating desired threshold values of the second living spaces A to D, where (a) illustrates the desired threshold values of the second living space A, and (b) illustrates the desired threshold values of the second living space B. , (C) shows the desired threshold value of the second living space C, and (d) shows the desired threshold value of the second living space D.

  As shown in FIG. 4, when the living space is the living space X, the desired threshold values are as follows in the second living spaces A to D adjacent thereto. That is, as shown in FIG. 4A, the desired threshold value is set to 21 dB in the second living space A. 4B to 4D, the desired threshold value is set to 19 dB in the second living space B, the desired threshold value is set to 23 dB in the second living space C, and the second living space D The desired threshold is set to 18 dB. The storage unit 72 stores the desired threshold value set as described above.

  The comparison unit 73 refers to the storage unit 72 and compares the volume level generated in the first living space measured by the measuring unit 71 with a desired threshold set in the second living space. That is, as shown in FIG. 3B, when the first living space is the living space X, the comparison unit 73, the volume level generated in the first living space X, the first living space X, and the top, bottom, left, and right Are compared with desired threshold values set in the second living spaces A to D adjacent to.

  The comparison unit 73 selects the minimum desired threshold prior to the comparison. That is, the comparison unit 73 selects the minimum desired threshold value among the desired threshold values for the second living spaces A to D as illustrated in FIG. At this time, the minimum desired threshold is the desired threshold of the second living space D. For this reason, the comparison unit 73 selects 18 dB of the second living space D as the minimum desired threshold value. In addition, when the 1st living space adjoins only one 2nd living space, the desired threshold value of the adjacent 2nd living space becomes a minimum threshold value as it is.

  Further, when selecting the minimum desired threshold value, the comparing unit 73 compares the selected minimum desired threshold value with the volume level measured by the measuring unit 71. That is, in the example illustrated in FIG. 4, the comparison unit 73 compares the desired threshold value of 18 dB with the volume level measured by the measurement unit 71.

  When the comparison unit 73 determines that the volume level measured by the measurement unit 71 exceeds the minimum desired threshold (18 dB in the above example), the comparison unit 73 outputs a signal to that effect. Thereby, the display part 30 will alert | report to the resident in the 1st living space X that a noise is high.

  Furthermore, the building control device 70 according to the present embodiment includes a specifying unit (specifying unit) 74 and a volume control unit (volume control unit) 75. The specifying unit 74 specifies a sound source that is a volume output source when it is determined that the volume level measured by the measuring unit 71 exceeds the minimum desired threshold. Specifically, the specifying unit 74 specifies a sound source that is a volume output source based on the volume information at the time of power-on transmitted from the display unit 30 or the component 40.

  The volume control unit 75 performs volume control so that the volume level of the volume output from the sound source specified by the specifying unit 74 is not more than the minimum desired threshold value. Thereby, it is not necessary for the resident to directly control the volume, and the volume can be adjusted so that the neighbor does not mind the noise.

  Reference is again made to FIG. In this embodiment, the home information breaker 60 has a changing function for changing a desired threshold value in the second living space stored in the storage unit 72 in response to a request from a resident in the second living space. That is, the home information breaker 60 functions as a setting unit that can variably set a desired threshold for comparison with the volume level in the first living space. Specifically, the home information breaker 60 has an operation unit, and a resident in the second living space can change the desired threshold value in the second living space by operating the operation unit. Thereby, optimization of the alerting | reporting in the 1st living space X can be aimed at.

  FIG. 5 is a diagram illustrating a desired threshold set by a resident in the second living space D. As shown in FIG. 5, it is assumed that a resident in the second living space D operates the home information breaker 60 to lower the desired threshold. In this case, the home information breaker 60 transmits a signal to the storage unit 72 of the building control device 70. Then, the storage unit 72 updates the desired threshold value. Thereby, for example, as shown in FIG. 5, the desired threshold value in the second living space D is lowered by “2”.

  For this reason, when noise of 16 dB or more is generated in the first living space X, the notification is performed in the first living space X. Similarly, the resident can change the desired threshold value by operating the home information breaker 60 in the other second living spaces A to C.

  Furthermore, when there are a plurality of first living spaces adjacent to the second living space, the home information breaker 60 may be configured to set a desired threshold value by designating the direction of the adjacent first living space. . In this case, for example, a resident in the second living space D operates the home information breaker 60 to select one of up, down, left, and right, and then performs an operation of lowering the desired threshold value. As an example, it is assumed that the resident of the second living space D designates only the first living space adjacent to the lower side and performs an operation of changing the desired threshold value. In this case, the desired threshold is changed only for the first living space adjacent to the lower side of the second living space D, and for the first living space adjacent in the other direction including the first living space X, The desired threshold value is not changed.

  In the above, the resident designates the first living space in which the desired threshold is changed. However, the present invention is not limited to this, and the first living space in which the desired threshold is changed is automatically searched, and the direction specified by the automatic search is set. The desired threshold value may be changed only for the first living space. In this case, when the resident of the second living space D performs an operation of changing the desired threshold value, the home information breaker 60 has a first living space (residential space adjacent to the second living space D from the building control device 70. Volume level information in X is included. Then, the home information breaker 60 automatically searches for the first living space in which the desired threshold value is changed based on the acquired volume level. At this time, the home information breaker 60 may specify the first living space with the highest volume level, or may specify the first living space closest to the desired threshold.

  Next, a noise detection method according to this embodiment will be described. FIG. 6 is a flowchart showing the noise detection method according to the present embodiment, and shows processing in the case where notification is performed by noise from the first living space. First, the building control device 70 determines whether or not the system itself is turned off (S1). When it is determined that the system itself has been turned off (S1: YES), the processing illustrated in FIG. 6 ends.

  When it is determined that the system itself is not turned off (S1: NO), the comparison unit 73 determines the minimum desired threshold value among the desired threshold values for the second living space (S2).

  Next, the measuring unit 71 measures the volume level generated in the first living space (S3). At this time, the measurement unit 71 measures the volume level based on the electrical signals from the microphone 10 and the vibration detector 20.

  Then, the comparison unit 73 determines whether or not the volume level measured in step S3 exceeds the minimum desired threshold value determined in step S2 (S4). If it is determined that the volume level measured in step S3 does not exceed the minimum desired threshold value determined in step S2 (S4: NO), the process proceeds to step S1.

  On the other hand, when it is determined that the volume level measured in step S3 exceeds the minimum desired threshold value determined in step S2 (S4: YES), the specifying unit 74 executes a process of specifying a sound source that is a volume output source. (S5). In this specifying process, the sound source is specified based on the volume information at the time of power-on transmitted from the display unit 30 or the component 40.

  Thereafter, the specifying unit 74 determines whether or not the sound source has been specified (S6). For example, when the sound volume is generated from a device other than the display unit 30 or the component 40 that is not incorporated in the noise detection system 1, the specifying unit 74 determines that the sound source cannot be specified (S6: NO), and processing Proceeds to step S8.

  On the other hand, when the loud sound is generated from the display unit 30 or the component 40, the specifying unit 74 determines that the sound source can be specified (S6: YES). Then, the volume control unit 75 reduces the volume of the identified sound source, and sets the volume level below the minimum desired threshold (S7). Thereafter, the display unit 30 notifies that the neighbor is troubled by noise (S8). Then, the process shown in FIG. 6 ends. In addition, when performing the notification, the display unit 30 may display that effect when the volume down in step S7 is being executed.

  FIG. 7 is a flowchart showing the noise detection method according to the present embodiment, and shows a process when the desired threshold value of the second living space is changed.

  First, the building control device 70 determines whether or not the system itself is turned off (S11). When it is determined that the system itself has been turned off (S11: YES), the processing illustrated in FIG. 7 ends. When it is determined that the system itself is not turned off (S11: NO), the home information breaker 60 determines whether or not a desired threshold value changing operation has been performed (S12).

  If it is determined that the desired threshold value changing operation has not been performed (S12: NO), the process proceeds to step S11. On the other hand, when it is determined that a desired threshold value changing operation has been performed (S12: YES), the home information breaker 60 transmits a signal to change the desired threshold value. Thereby, the memory | storage part 72 changes and memorize | stores a desired threshold value (S13). Thereafter, the process proceeds to step S11.

  Thus, according to the noise detection system 1 and the noise detection method according to the present embodiment, the measurement is performed using the minimum desired threshold value among the desired threshold values for the second living spaces A to D and the first living space X. The sound volume level is compared, and if it is determined that the measured sound volume level exceeds the minimum desired threshold value, the resident in the first living space X is notified. As a result, when excessive noise is produced, attention is drawn and noise suppression can be achieved. Furthermore, since the desired threshold value in the second living spaces A to D can be variably set, the desired threshold value is optimized for a resident who is very concerned about noise or a resident who does not care much about noise. Can be achieved. Therefore, the notification can be optimized.

  Further, a corresponding one of a plurality of desired threshold values is selected according to the resident's behavior for each of the second living spaces A to D, and the minimum desired threshold value among the selected desired threshold values, the measured volume level, Compare Here, for example, the degree of concern for noise varies depending on whether the neighbor is sleeping or listening to music. For this reason, by setting a plurality of desired thresholds according to actions such as whether sleeping or listening to music, by comparing the minimum desired threshold among the selected desired thresholds and the measured volume level, Notification can be made appropriate.

  In addition, when there are a plurality of adjacent first living spaces, the desired threshold value can be set by specifying the direction of the adjacent first living space, so that the cause of the noise is clearly the resident of the first living space adjacent to the specific direction For example, in the case where it is caused by the above, it is possible to optimize the notification without harming the lives of residents in other adjacent first living spaces.

  Further, the first living space whose desired threshold is changed is automatically searched based on the volume level of the adjacent first living space, and is compared with the volume level measured in the first living space in the direction specified by the automatic search. Change the desired threshold. For this reason, even if the direction of the 1st living space which causes noise among the adjacent 1st living spaces is unknown, it is designated by automatic search, and the life etc. of the resident of other adjacent 1st living spaces Appropriate notification can be achieved without harm.

  In addition, when it is determined that the measured volume level exceeds the minimum desired threshold, the sound source that is the output source of the volume is specified, and the volume level of the volume output from the specified sound source is equal to or less than the minimum desired threshold. Volume control is performed so that For this reason, it is not necessary for the resident in the living room space X to directly control the volume, and the volume can be adjusted so that the neighbor does not mind the noise. Thereby, the complaint generation with a resident and a neighbor can be suppressed extremely.

  Next, a second embodiment of the present invention will be described. The noise detection system 1 and the noise detection method according to the second embodiment are the same as those of the first embodiment, but the configuration and processing contents are different from those of the first embodiment. Hereinafter, differences will be described.

  FIG. 8 is a functional block diagram showing details of the building control device 70 according to the second embodiment. As shown in FIG. 8, the building control device 70 newly includes a behavior detection unit (behavior detection means) 76.

  The behavior detection unit 76 detects a behavior of a resident in the second living space adjacent to the first living space. The behavior detection unit 76 uses the power-on information and volume information from the display unit 30, the power-on information and volume information from the component 40, and the weight information from the weight sensor 50, so that the resident is “resting” and “sleeping”. It detects which action is being taken, such as “medium”, “watching movie TV”, or “watching music”. In the present embodiment, the home information breaker 60 can be set to that effect when going out. For this reason, the behavior detection unit 76 can detect “out of office” by a signal from the home information breaker 60.

  In the second embodiment, the storage unit 72 stores a desired threshold according to the behavior of the resident in the second living space. Here, with reference to FIG. 9, the desired threshold value according to the action of the resident of 2nd living space AD is demonstrated. FIG. 9 is a diagram illustrating a desired threshold according to the behavior of the residents in the second living spaces A to D, where (a) illustrates the desired threshold of the second living space A, and (b) illustrates the second residential space. The desired threshold value of the space B is shown, (c) shows the desired threshold value of the second living space C, and (d) shows the desired threshold value of the second living space D.

  As shown in FIG. 9A, when the behavior of the resident in the second living space A is “resting”, the desired threshold is set to 21 dB, and when the behavior of the resident is “sleeping”, The desired threshold is set to 11 dB. When the resident's action is “watching movie TV” and “music watching”, the desired threshold is set to 31 dB, and when the resident action is “going out”, the desired threshold is set to ∞ dB. Is set. Furthermore, in the case of “default”, the desired threshold value is set to 41 dB.

  As shown in FIG. 9B, when the behavior of the resident in the second living space B is “resting”, the desired threshold is set to 22 dB, and when the behavior of the resident is “sleeping”, The desired threshold is set to 12 dB. In addition, when the resident's action is “watching movie TV” and “music watching”, the desired threshold is set to 32 dB, and when the resident action is “going out”, the desired threshold is set to ∞ dB. Is set. Further, in the case of “default”, the desired threshold is set to 42 dB.

  As shown in FIG. 9C, when the resident's action in the second living space C is “resting”, the desired threshold is set to 23 dB, and when the resident's action is “sleeping”, The desired threshold is set to 13 dB. In addition, when the resident's action is “watching movie TV” and “music watching”, the desired threshold is set to 33 dB, and when the resident action is “going out”, the desired threshold is set to ∞ dB. Is set. Furthermore, in the case of “default”, the desired threshold value is set to 43 dB.

  As shown in FIG. 9 (d), when the behavior of the resident in the second living space D is “resting”, the desired threshold is set to 24 dB, and when the behavior of the resident is “sleeping”, The desired threshold is set to 14 dB. When the resident's action is “watching movie TV” and “music watching”, the desired threshold is set to 34 dB. When the resident action is “going out”, the desired threshold is set to ∞ dB. Is set. Furthermore, in the case of “default”, the desired threshold value is set to 44 dB.

  In the second embodiment, the comparison unit 73 refers to the storage unit 72 and selects a desired threshold associated with the resident's action for each second living space detected by the action detection unit 76.

  FIG. 10 is a diagram showing desired threshold values selected by the comparison unit 73 shown in FIG. For example, when the behavior detected by the behavior detecting unit 76 in the second living space A is “sleeping”, the comparing unit 73 selects a desired threshold value of 11 dB for the second living space A. Similarly, the comparison unit 73 selects a desired threshold value of 22 dB when the behavior detected by the behavior detection unit 76 in the second living space B is “resting”. Further, when the behavior detected by the behavior detection unit 76 in the second living space C is “during break”, the comparison unit 73 selects a desired threshold value of 23 dB. Furthermore, the comparison unit 73 selects a desired threshold value of 34 dB when the behavior detected by the behavior detection unit 76 in the second living space D is “watching movie television”.

  In particular, in the case of this embodiment, since the first living space is adjacent to the four second living spaces, the minimum threshold value among the selected threshold values is further selected.

  The comparison unit 73 will be described again. The comparison unit 73 compares the minimum desired threshold value among the desired threshold values for the selected second living spaces A to D with the sound volume level measured by the measurement unit 71. That is, in the example shown in FIG. 5, the minimum desired threshold is 11 dB. For this reason, the comparison unit 73 compares the desired threshold value of 11 dB with the volume level measured by the measurement unit 71. When the first living space is adjacent to only one second living space, the threshold selected according to the behavior of the resident in the second living space becomes the minimum threshold as it is, and the volume measured by the measuring unit 71 Will be compared to the level.

  If the comparison unit 73 determines that the volume level measured by the measurement unit 71 exceeds the minimum desired threshold (11 dB in the above example), the comparison unit 73 outputs a signal to that effect. Thereby, the display part 30 will alert | report to the resident in the 1st living space X that a noise is high.

  Furthermore, in the second embodiment, the home information breaker 60 can change the desired threshold value stored in the storage unit 72 according to the behavior of the resident in the second living space. FIG. 11 is a diagram illustrating a desired threshold value set in the second living space A according to the behavior of the resident in the second living space A.

  As shown in FIG. 11, it is assumed that a resident in the second living space A inputs “sleeping” to the home information breaker 60 and performs an operation of lowering the desired threshold. In this case, the home information breaker 60 transmits a signal to the storage unit 72 of the building control device 70. Then, the storage unit 72 updates the desired threshold value. As a result, for example, as shown in FIG. 11, the desired threshold value of “sleeping” in the second living space A is lowered by “2”.

  For this reason, when a resident in the second living space A is “sleeping” and noise of 9 dB or more is generated in the first living space X, a notification is made in the first living space X. Similarly, for the other second living spaces B to D, the resident can operate the home information breaker 60 to change the desired threshold stored in the storage unit 72 according to the action.

  Further, in the example shown in FIG. 11, only the desired threshold value in “sleeping” is lowered, but not limited to this, “resting”, “watching movie TV”, “watching music”, and “default” May also be lowered at the same time. Further, in the example shown in FIG. 7, “being sleeping” is detected by the behavior detecting unit 76 when the resident in the second living space A inputs and specifies “sleeping” to the home information breaker 60. However, the present invention is not limited to this, and “being sleeping” may be automatically detected by the behavior detection unit 76.

  Furthermore, the home information breaker 60 may include a switch or the like that can select whether the behavior is detected manually by the behavior detector 76 or whether the behavior is automatically detected by the behavior detector 76.

  In addition, when there are a plurality of adjacent first living spaces with respect to the second living space, the home information breaker 60 designates the direction of the adjacent first living space and sets a desired threshold value, as in the first embodiment. It may be settable, or the first threshold value may be automatically searched for the first living space for changing the desired threshold value, and the desired threshold value may be changed only for the first living space in the direction specified by the automatic search. Good.

  Next, a noise detection method according to the second embodiment will be described. FIG. 12 is a flowchart showing a noise detection method according to the second embodiment, and shows a process in the case where notification is performed by noise in the first living space. In FIG. 12, the same processes as those in FIG.

  As shown in FIG. 12, when it is determined that the system itself is not turned off (S1: NO), the behavior detecting unit 76 detects the behavior of the resident in the second living space (S21). At this time, the behavior detecting unit 76 uses the power-on information and the volume information from the display unit 30, the power-on information and the volume information from the component 40, the weight information from the weight sensor 50, and the like. A person's behavior is detected.

  Next, the comparison unit 73 selects a desired threshold corresponding to each second living space from the behavior of the resident in the second living space detected in step S21 (S22). And the comparison part 73 determines the minimum desired threshold value among the desired threshold values selected in step S22 (S2). Thereafter, the processing shown in FIG. 12 is executed in the same manner as the processing of steps S3 to S8 shown in FIG.

  FIG. 13 is a flowchart showing a noise detection method according to the second embodiment, and shows a process when the desired threshold value of the second living space is changed. In FIG. 13, the same processes as those in FIG.

  As shown in FIG. 13, when it is determined that a desired threshold value changing operation has been performed (S12: YES), the home information breaker 60 determines whether or not behavior detection is automatic for the resident in the second living space. (S31). When it is determined that it is automatic (S31: YES), the behavior detection unit 76 determines whether or not the behavior can be detected (S32). If it is determined that the behavior can be detected (S32: YES), the home information breaker 60 transmits a signal to change the desired threshold based on the detected behavior. Thereby, the memory | storage part 72 changes and memorize | stores the desired threshold value corresponding to the detected action (S33). Thereafter, the process proceeds to step S11.

  When it is determined that the behavior cannot be detected (S32: NO), the home information breaker 60 transmits a signal to change the entire desired threshold value. Thereby, the memory | storage part 72 changes and memorize | stores the whole desired threshold value (S34). Thereafter, the process proceeds to step S11.

  When it is determined that it is not automatic (S31: NO), the home information breaker 60 determines whether or not an action is input (S35). If it is determined that an action has been input (S35: YES), the home information breaker 60 transmits a signal to change the desired threshold based on the input action. Thereby, the memory | storage part 72 changes and memorize | stores the desired threshold value corresponding to the detected action (S36). Thereafter, the process proceeds to step S11.

  When it is determined that no action has been input (S35: NO), the home information breaker 60 transmits a signal to change the entire desired threshold. Thereby, the memory | storage part 72 changes and memorize | stores the whole desired threshold value (S36). Thereafter, the process proceeds to step S11.

  Thus, according to the noise detection system 1 and the noise detection method according to the second embodiment, the same effects as those of the first embodiment can be obtained.

  Furthermore, according to 2nd Embodiment, the minimum desired threshold value among the desired threshold values according to the resident's action for every 2nd living space AD is compared with the measured sound volume level. Here, for example, the degree of concern for noise varies depending on whether the neighbor is sleeping or listening to music. For this reason, it is possible to optimize notification by comparing the minimum desired threshold value among the desired threshold values according to the action such as whether the user is sleeping or listening to music, and the measured volume level.

  Next, a third embodiment of the present invention will be described. The noise detection system 1 and the noise detection method according to the third embodiment are the same as those of the first embodiment, but the configuration and processing contents are different from those of the first embodiment. Hereinafter, differences will be described.

  FIG. 14 is a functional block diagram showing details of the building control device 70 according to the third embodiment. As shown in FIG. 8, the building control device 70 is newly provided with a time detection unit (time detection means) 77. The time detector 77 detects time. Moreover, the memory | storage part 72 has memorize | stored the desired threshold value according to time for every living space.

  FIG. 15 is a diagram illustrating a desired threshold value of the second living space A according to time. In the example illustrated in FIG. 15, only the second living space A will be described as an example.

  As shown in FIG. 15, the threshold value is set for four times of “morning”, “daytime”, “night”, and “midnight”. Specifically, as shown in FIG. 15, when the time is “morning”, the threshold is set to 16 dB, and when the time is “daytime”, the threshold is set to 31 dB. Further, when the time is “night”, the threshold is set to 21 dB, and when the time is “midnight”, the threshold is set to 11 dB. Furthermore, in the case of “default”, the threshold is set to 41 dB. Moreover, the memory | storage part 72 memorize | stores the threshold value set like FIG.

  Since it is configured in this way, in the second embodiment, the comparison unit 73 compares the threshold selected according to time with the volume level measured by the measurement unit 71. When the comparison unit 73 determines that the volume level measured by the measurement unit 71 exceeds the threshold value, the comparison unit 73 outputs a signal to that effect. Thereby, the display part 30 will alert | report to the resident in the 1st living space X that a noise is high.

  In the case of the third embodiment, since the first living space is adjacent to the four second living spaces, the minimum threshold among the selected thresholds is further selected.

  Furthermore, in the third embodiment, the home information breaker 60 can change the desired threshold value stored in the storage unit 72 according to the time. FIG. 16 is a diagram illustrating a desired threshold value set in the second living space A according to the behavior of the resident in the second living space A.

  As shown in FIG. 16, it is assumed that a resident in the second living space A inputs “midnight” to the home information breaker 60 and lowers the desired threshold. In this case, the home information breaker 60 transmits a signal to the storage unit 72 of the building control device 70. Then, the storage unit 72 updates the desired threshold value. Thereby, as shown in FIG. 16, for example, the desired threshold value of “midnight” in the second living space A is lowered by “2”.

  For this reason, when noise of 9 dB or more occurs in the first living space X at midnight, a notification is performed in the first living space X. Similarly, for the other second living spaces B to D, the resident can operate the home information breaker 60 to change the desired threshold stored in the storage unit 72 according to the time.

  Further, in the example shown in FIG. 16, only the desired threshold value at “late night” is decreased, but not limited to this, “morning”, “daytime”, “night”, and “default” are also decreased at the same time. It may be like this. In the example shown in FIG. 16, the resident in the second living space A inputs “midnight” to the home information breaker 60 and designates it, and “midnight” is detected by the time detection unit 77. However, the time detection unit 77 may automatically detect “midnight” based on the current time.

  Furthermore, the home information breaker 60 may include a switch or the like that can select whether the time is detected manually by the time detector 77 or whether the time is automatically detected by the time detector 77.

  In addition, when there are a plurality of adjacent first living spaces with respect to the second living space, the home information breaker 60 designates the direction of the adjacent first living space and sets a desired threshold value, as in the first embodiment. It may be settable, or the first threshold value may be automatically searched for the first living space for changing the desired threshold value, and the desired threshold value may be changed only for the first living space in the direction specified by the automatic search. Good.

  Next, a noise detection method according to the third embodiment will be described. FIG. 17 is a flowchart showing a noise detection method according to the third embodiment, and shows a process in the case where notification is performed by noise in the first living space. In FIG. 17, the same processes as those in FIG.

  As shown in FIG. 17, when it is determined that the system itself is not turned off (S1: NO), the time detection unit 77 detects the time (S41). Next, the comparison unit 73 selects a desired threshold corresponding to each second living space from the time detected in step S41 (S42). And the comparison part 73 determines the minimum desired threshold value among the desired threshold values selected in step S42 (S2). Thereafter, the processing shown in FIG. 17 is executed in the same manner as the processing of steps S3 to S8 shown in FIG.

  FIG. 18 is a flowchart showing a noise detection method according to the third embodiment, and shows a process for changing the desired threshold value of the second living space. In FIG. 18, the same processes as those in FIG.

  As shown in FIG. 12, when it is determined that a desired threshold value changing operation has been performed (S12: YES), the home information breaker 60 determines whether or not time detection is automatic for residents in the second living space. (S51). When it is determined that the time is automatic (S51: YES), the time detection unit 77 determines whether or not the time has been detected (S52). If it is determined that the time has been detected (S52: YES), the home information breaker 60 transmits a signal to change the desired threshold based on the detected time. Thereby, the memory | storage part 72 changes and memorize | stores the desired threshold value corresponding to the detected time (S53). Thereafter, the process proceeds to step S11.

  When it is determined that the time could not be detected (S52: NO), the home information breaker 60 transmits a signal to change the entire desired threshold. Thereby, the memory | storage part 72 changes and memorize | stores the whole desired threshold value (S54). Thereafter, the process proceeds to step S11.

  When it is determined that it is not automatic (S51: NO), the home information breaker 60 determines whether or not the time has been input (S55). When it is determined that the time has been input (S55: YES), the home information breaker 60 transmits a signal to change the desired threshold based on the input time. Thereby, the memory | storage part 72 changes and memorize | stores the desired threshold value corresponding to the detected time (S56). Thereafter, the process proceeds to step S11.

  If it is determined that the time has not been input (S35: NO), the home information breaker 60 transmits a signal to change the entire desired threshold. Thereby, the memory | storage part 72 changes and memorize | stores the whole desired threshold value (S36). Thereafter, the process proceeds to step S11.

  Thus, according to the noise detection system 1 and the noise detection method according to the third embodiment, the same effects as those of the first embodiment can be obtained.

  Furthermore, according to 3rd Embodiment, the minimum desired threshold value among the desired threshold values for every 2nd residence area matched with the detected time is compared with the measured sound volume level. Here, for example, the degree of concern for the neighbor changes according to the time. For this reason, it is possible to further optimize the notification by selecting the desired threshold according to the time.

  As mentioned above, although this invention was demonstrated based on embodiment, this invention is not limited to the said embodiment, You may add a change in the range which does not deviate from the meaning of this invention, and combines each embodiment. Also good.

  For example, as shown in FIG. 19, the second embodiment and the third embodiment may be combined. FIG. 19 is a diagram illustrating a desired threshold value of the second living space A according to behavior and time. As shown in FIG. 19, when the behavior of the resident in the second living space A is “resting”, the desired threshold is set to 15 dB when the time corresponds to morning, noon and night time. When it corresponds to midnight time, the desired threshold is set to 10 dB.

  Further, when the behavior of the resident in the second living space A is “sleeping”, when the time corresponds to morning and night time, the desired threshold is set to 10 dB, and the time corresponds to night time The desired threshold is set to 7 dB. Furthermore, when the time corresponds to midnight, the desired threshold is set to 5 dB.

  Further, when the behavior of the resident in the second living space A is “watching movie TV” and “watching music”, the desired threshold is set to ∞ dB when the time corresponds to morning, noon and night time. When the time corresponds to midnight, the desired threshold is set to 60 dB.

  Further, in the case of “default”, the desired threshold is set to 20 dB when the time corresponds to morning, noon, and night time, and the desired threshold is set to 15 dB when the time corresponds to midnight time. FIG. 6 shows only the desired threshold for the second living space A, but the same applies to the other second living spaces.

  Thus, the memory | storage part 72 has memorize | stored the desired threshold value according to action and time. For this reason, the comparison unit 73 selects a desired threshold value associated with the detected action and time, and compares it with the volume level. Thereby, it is possible to further optimize the notification.

  Moreover, in the said embodiment, although the noise detection system 1 serves as network environment equipment, it is not restricted to this, The noise detection system 1 may be used independently.

  Moreover, it is desirable that the desired threshold value for each living space is automatically set based on the housing information regarding the housing for each living space. Here, the frame refers to the thickness of the wall, the material of the wall, the structure of the building such as a reinforcing bar and a wooden structure. The sound volume generated in the living space is transmitted as noise to the adjacent living space under the influence of the housing. For this reason, a desired threshold value should change according to a housing. Therefore, by automatically setting the desired threshold value based on the housing information about the housing for each living space, it is possible to set the desired threshold value according to the structure of the apartment, the hotel, etc., and further improve the notification. Note that the frame information is input by transmitting information from a predetermined device to the setting unit 73 of the building control device 70.

  Further, in the present embodiment, the desired threshold values are all different depending on the behavior, but not limited to this, only one desired threshold value may be different, such as “sleeping”. Each desired threshold value may be set by a manufacturer, or may be set by a manager of a housing complex. Furthermore, the desired threshold value may be set by itself without being limited to the neighbor.

  In the present embodiment, the desired threshold value may be changed in any manner depending on the time. For example, only one desired threshold may be different such as “midnight”, or all desired thresholds may be different. Furthermore, in the present embodiment, it is divided into “morning”, “daytime”, “night”, and “midnight”, but not limited to this, it may be divided in time units such as “9 to 10 o'clock”. It may be good or divided up to the minute.

  Furthermore, in this embodiment, the desired threshold value in the second living space is changed by the resident in the second living space through the home information breaker 60. However, the present invention is not limited to this. For example, it may be changed by a resident of the first living space X, or may be changed by a manager.

  Furthermore, in the said embodiment, although the 2nd living space adjacent to a 1st living space is four, it is not restricted to this in particular, One to three may be sufficient and five or more may be sufficient .
