Summary of the Invention

Problems to be Solved by the Invention

[0004] In a building with multiple floors (more specifically, three or more floors), the impact sound accompanied by vibration generated in the first living space may affect the second living space existing on a floor below the first living space through the building structure.

[0005] Therefore, the present invention has been made in view of the above problems, and an object thereof is to provide a living environment management facility capable of appropriately confirming the influence of impact sound on a second living space existing on a floor below the first living space when impact sound occurs in the first living space.

Means for Solving the Problems

[0006] The above object is achieved according to the information processing apparatus of the present invention, which includes a vibration sensor provided on each floor in a multi-story building and a processing apparatus. The processing apparatus performs a first specifying process of specifying the magnitude of vibration in the first living space based on an output signal from the vibration sensor provided on the floor where the first living space exists, and when the magnitude of vibration in the specified first living space becomes equal to or greater than a first set value, a second specifying process of specifying the magnitude of vibration in a second living space existing on a floor below the first living space based on an output signal from the vibration sensor provided on the floor where the second living space exists, and a warning process of issuing a warning to the first living space when the magnitude of vibration in the specified second living space becomes equal to or greater than a second set value.

[0007] In the living environment management facility of the present invention, the processing apparatus specifies the magnitude of vibration in the second living space based on an output signal from the vibration sensor provided on the floor where the second living space exists. Therefore, even if it is not a second living space existing on a floor close to the first living space, as long as it is a second living space existing on a floor below the first living space, the magnitude of vibration can be appropriately specified. As a result, the influence of impact sound on the second living space existing on a floor below the first living space can be appropriately confirmed.

[0008] Further, the living environment management facility may further include a sound sensor provided in the second living space. When the magnitude of vibration in the specified second living space becomes equal to or greater than a second set value, the processing apparatus may further perform a third specifying process of specifying the increase amount of the sound magnitude in the second living space based on an output signal from the sound sensor, and when the increase amount becomes equal to or greater than a predetermined value, perform a warning process of issuing a warning to the first living space. Even when the magnitude of vibration in the second living space is equal to or greater than the second set value, if noise other than the impact sound from the first living space is generated in the second living space, the degree of influence of the impact sound from the first living space will be reduced. Regarding this, with the above configuration, since it is possible to check the increase in the sound volume in the second living space when the impact sound is generated in the first living space, it is possible to appropriately check the influence of the impact sound from the first living space in the second living space.

[0009] In addition, a vibration sensor is provided in each of a plurality of living spaces including the first living space and the second living space, and the processing device may identify the first living space from among the plurality of living spaces based on the output signals from the vibration sensors provided in each of the plurality of living spaces in a first specific process. With the above configuration, it is possible to appropriately identify the first living space that generates the impact sound from among the living spaces.

[0010] Also, the second living space may be a living space on a floor that is two or more floors below the first living space. With the above configuration, it is possible to appropriately check the influence of the impact sound on the living space on a floor that is two or more floors below the first living space.

Effect of the Invention

[0011] According to the present invention, it is possible to provide a living environment management facility capable of appropriately checking the influence of impact sound on a second living space existing on a floor below the first living space when the impact sound is generated in the first living space.

Mode for Carrying Out the Invention

[0013] Hereinafter, one embodiment of the present invention (hereinafter, this embodiment) will be described with reference to the accompanying drawings. In the following embodiments, a "house" is cited as an example of a building. However, the present invention can be implemented in various buildings such as buildings other than houses, for example, facilities such as offices, stores, hospitals, or schools, and buildings in factories. In addition, in this specification, the concept of "device" includes a single device that exhibits a specific function by itself, as well as a combination of a plurality of devices that are distributed and exist independently while cooperating (collaborating) to exhibit a specific function. In addition, since the basic information processing technologies (communication / transmission technology, information acquisition technology, information recording technology, information processing technology, information analysis technology, image processing technology, visualization technology, etc.) for realizing the content of this embodiment are well-known technologies, the description thereof will be omitted.

[0014] <<Outline of Warning Processing According to This Embodiment>> First, the outline of the warning process (hereinafter, this warning process) implemented using the living environment management facility (hereinafter, living environment management facility 10) according to this embodiment will be described with reference to FIG. 1. In this warning process, in a multi-story house, when an impact sound accompanied by vibration occurs in any living space, it is determined whether there is an impact on the living space on the floor below the living space where the impact sound occurred. If there is an impact, a warning is given to the living space where the impact sound occurred. "Residence" means, for example, apartment buildings with three or more floors and collective housing such as apartments. The residence 100 shown in FIG. 1 is a four-story collective housing. "Impact sound accompanied by vibration" means, in the living space, for example, the impact sound generated when a resident runs around, jumps, drops an object, or when a device such as a washing machine operates.

[0015] On each floor of the residence 100, three living spaces are arranged side by side. The living space is a space where residents live, and it is assumed that different households live in each living space. In the residence 100 shown in FIG. 1, on the first floor, they are arranged in the order of living spaces 101, 102, 103 from the left in the figure; on the second floor, they are arranged in the order of living spaces 201, 202, 203 from the left in the figure; on the third floor, they are arranged in the order of living spaces 301, 302, 303 from the left in the figure; on the fourth floor, they are arranged in the order of living spaces 401, 402, 403 from the left in the figure. Also, in the height direction, they are arranged from the lower floor to the upper floor in the order of living spaces 101, 201, 301, 401, in the order of living spaces 102, 202, 302, 402, and in the order of living spaces 103, 203, 303, 403.

[0016] Next, an example of this warning process will be shown using FIG. 1. In the following description, it is assumed that the living space 402 on the fourth floor is the first living space that generates an impact sound accompanied by vibration. As shown in FIG. 1, vibration sensors 11 (to be described later) are respectively provided in each living space on each floor, and in this warning process, output signals from all the vibration sensors 11 are constantly acquired (constantly measured). When an impact sound accompanied by vibration occurs in any one of the living spaces on the floors above the lowest floor (floors 2 to 4 in FIG. 1), based on the output signals from the respective vibration sensors 11 provided in each living space on floors 2 to 4, the first living space that is the source of the impact sound is identified from among the living spaces on floors 2 to 4, and the magnitude of the vibration in that first living space is identified. For example, when an impact sound occurs in the living space 402 on the fourth floor, the living space 402 is identified as the first living space, and the magnitude of the vibration in the living space 402 is identified. Note that the "lowest floor" means the first floor in a house without a living space in the basement, that is, the house 100 shown in FIG. 1, but in a house with a living space in the basement, it means the floor located at the lowest position among the basement floors.

[0017] Next, it is determined whether or not the magnitude of the vibration in the first living space is equal to or greater than a preset first set value. When it is determined that the magnitude of the vibration is equal to or greater than the first set value, all of the living spaces on floors 1 to 3 that are below the first living space (living space 402) are identified as second living spaces, and the magnitude of the vibration in each of the living spaces identified as the second living spaces is respectively identified.

[0018] Next, it is determined whether the magnitude of the vibration of each of the living spaces on the 1st to 3rd floors specified as the second living space is equal to or greater than a preset second set value. Then, among each of the second living spaces, the floor where the living space determined to have a vibration magnitude equal to or greater than the second set value exists is specified as the floor affected by the impact sound, and the fact that there was an impact sound on the specified floor is notified (warned) to the occupant of the first living space through a warning device 13 described later. For example, among each of the living spaces on the 1st to 3rd floors specified as the second living space, if the magnitude of the vibration in living spaces 103 and 202 is equal to or greater than the second set value, the 1st and 2nd floors where living spaces 103 and 202 exist are specified as the floors affected by the impact sound, and the fact that there was an impact sound on the 1st and 2nd floors is notified (warned) to the occupant of living space 302. Note that instead of notifying the occupant of the first living space of the floors to be warned, the living spaces affected by the impact sound (that is, living spaces 103 and 202) may be notified to the occupant of the first living space.

[0019] <<Regarding the configuration of the living environment management equipment>> Next, the living environment management equipment 10 used when implementing this warning process will be described with reference to FIGS. 1 and 2. The living environment management equipment 10 is equipment installed attached to a house as shown in FIG. 1. Specifically, as shown in FIG. 2, it includes a plurality of vibration sensors 11, a processing device 12, and a plurality of warning devices 13.

[0020] The vibration sensor 11 is a sensor that converts vibration into an electrical signal (output signal), and at least one is provided on each floor. In the example shown in FIG. 1, the vibration sensor 11 is provided in each of a plurality of living spaces including the first living space and the second living space. The vibration sensor 11 is, for example, an acceleration sensor and outputs an electrical signal (output signal) corresponding to the acceleration. The vibration sensor 11 is, for example, an acceleration sensor that detects the acceleration in each of the three axial directions, and its method is not particularly limited and may be, for example, a piezoelectric method, a piezoresistive method, or a capacitance method. Further, the vibration sensor 11 may constantly measure minute vibrations, and minute vibrations are minute vibrations that constantly exist on the ground surface and structures. The installation position of the vibration sensor 11 is not particularly limited and may be any of the ceiling, wall, floor surrounding the living space, and the building structure such as beams and columns. In the example shown in FIG. 1, the vibration sensors 11 are provided respectively in the ceiling spaces of each living space 101, 102, 103 on the first floor, in both the ceiling spaces and under the floors of each living space 201, 202, 203, 301, 302, 303 on the second and third floors, and under the floors of each living space 401, 402, 403 on the fourth floor.

[0021] The processing device 12 consists of a computer and is composed of, for example, a personal computer (PC), a workstation, or a server computer. The processing device 12 may be composed of a single computer, or may be composed of a plurality of computers in parallel and distributed. Further, when the computer constituting the processing device 12 is a server computer, it may be a server computer for ASP (Application Service Provider), SaaS (Software as a Service), PaaS (Platform as a Service), or IaaS (Infrastructure as a Service).

[0022] As shown in FIG. 2, the computer constituting the processing device 12 has a processor 12a, a memory 12b, a communication interface 12c, a storage 12d, an input device 12e, and an output device 12f.

[0023] The processor 12a is composed of, for example, a CPU (Central Processing Unit), an MPU (Micro-Processing Unit), an MCU (Micro Controller Unit), a GPU (Graphics Processing Unit), a DSP (Digital Signal Processor), a TPU (Tensor Processing Unit), or an ASIC (Application Specific Integrated Circuit). The memory 12b is composed of semiconductor memories such as ROM (Read Only Memory) and RAM (Random Access Memory). The communication interface 12c is composed of, for example, a network interface card, a communication interface board, or the like. The computer constituting the processing device 12 can communicate with other devices connected to the Internet, a mobile communication line, or the like via the communication interface 12c.

[0024] The storage 12d is composed of, for example, a flash memory, an HDD (Hard Disc Drive), an SSD (Solid State Drive), an FD (Flexible Disc), an MO disk (Magneto - Optical disc), a CD (Compact Disc), a DVD (Digital Versatile Disc), an SD card (Secure Digital card), or a USB memory (Universal Serial Bus memory). Note that the storage 12d may be built into the computer main body constituting the processing device 12 or may be attached to the computer main body in an external form. The input device 12e is composed of, for example, a keyboard, a mouse, or a touch panel. The output device 12f is composed of, for example, a display and a speaker.

[0025] In the computer constituting the processing device 12, as software, a program for an operating system (OS) and a program for warning processing are installed. By these programs being read out and executed by the processor 12a, the computer constituting the processing device 12 exhibits the function as the processing device 12, and specifically, executes a series of information processing related to this warning processing.

[0026] The warning device 13 warns the residents of the first living space of the floor where the second living space is determined to exist with a vibration magnitude equal to or greater than the second set value. The warning device 13 has, for example, an output unit, and the output unit outputs information regarding the target floor. The output unit may, for example, display character information (characters such as "1st floor") of the target floor on the screen, or may have lamps corresponding to each floor and light the lamp of the target floor, for example, in red, or may have sound signals corresponding to each floor and sound the sound signal of the target floor. Further, the warning device 13 may, for example, display character information indicating that there is no influence of the impact sound on the screen for floors other than the target floor, or may light a lamp, for example, in blue indicating that there is no influence of the impact sound. The warning device 13 is provided on a floor above the lowest floor, and in the example shown in FIG. 1, it is provided in each living space on the 2nd to 4th floors. Note that the warning device 13 may output information regarding the target living space instead of outputting information regarding the target floor.

[0027] <<Regarding the functions of the living environment management equipment according to the present embodiment>> Next, the configuration of the processing device 12 according to the present embodiment will be described again from a functional aspect. As shown in FIG. 3, the processing device 12 includes an acquisition processing unit 31, a first specifying processing unit 32, a first determination processing unit 33, a second specifying processing unit 34, a second determination processing unit 35, and a warning processing unit 36. These functional units are realized by the cooperation of the hardware devices included in the computer constituting the processing device 12 and the program (that is, software) installed in the computer. Hereinafter, each functional unit will be described.

[0028] <Acquisition processing unit> The acquisition processing unit 31 acquires the output signals from the vibration sensors 11 provided on each floor, more specifically, the vibration sensors 11 provided in each of a plurality of living spaces. The acquisition processing unit 31 constantly acquires the output signals from the vibration sensors 11 at preset sampling periods (for example, 10 to 100 msec, etc.). Since the acquisition processing unit 31 acquires the output signals from each vibration sensor 11 while synchronizing among the vibration sensors 11, in a process described later (specifically, the first specifying processing unit 32), the output signals at the same time points among different vibration sensors 11 can be compared. The acquisition processing unit 31 may store the acquired output signals of each vibration sensor 11 in the storage 12d of the processing device 12.

[0029] <First specifying processing unit> Based on the output signals from the vibration sensors 11 provided in each of a plurality of living spaces, the first specifying processing unit 32 specifies the first living space from among the plurality of living spaces, and based on the output signals from the vibration sensors 11 provided on the floor where the first living space exists, executes a process (corresponding to the first specifying process) of specifying the magnitude of vibration in the first living space. More specifically, the first specifying processing unit 32 specifies the largest output signal among the output signals at the same time points (or during the same period) from the vibration sensors 11 on the floors above the lowest floor (floors 2 to 4 in FIG. 1). Then, the first specifying processing unit 32 specifies the living space in which the vibration sensor 11 indicating the largest output signal is provided as the first living space. It is assumed that the output signal is an analog output signal. Also, instead of the output signal, a value corresponding to the output signal, specifically, a value related to vibration calculated based on the output signal (for example, acceleration (m / s 2 )) may be used, or a value obtained by converting vibration into noise (noise level (dB)) may be used.

[0030] Next, the first specifying processing unit 32 specifies the magnitude of vibration in the first living space based on the output signals from the vibration sensors 11 provided in the first living space. The "magnitude of vibration" is a value related to vibration calculated based on the output signals from the vibration sensors 11 (for example, acceleration (m / s 2It may be the value obtained by converting vibration into noise (noise level (dB)), and this value (level) may be the absolute value of the magnitude of vibration at the time when the target output signal is acquired, or may be the increase amount (relative value) from immediately before that time (for example, 1 to 5 seconds before).

[0031] <First determination processing unit> The first determination processing unit 33 compares the magnitude of vibration in the specified first living space with a preset first set value, and determines whether the magnitude of the vibration is equal to or greater than the first set value.

[0032] <Second specification processing unit> When the magnitude of vibration in the specified first living space becomes equal to or greater than the first set value, the second specification processing unit 34 specifies the magnitude of vibration in the second living space existing on the floor below the first living space, based on the output signal from the vibration sensor 11 provided on the floor where the second living space exists (corresponding to the second specification process). More specifically, the second specification processing unit 34 specifies all living spaces existing on the floors below the first living space, that is, all living spaces on the floor one level below the first living space and all living spaces on each floor two or more levels below the first living space, as the second living space.

[0033] Next, for each living space specified as the second living space, the second specification processing unit 34 specifies the magnitude of vibration during the period until a certain time has elapsed since the magnitude of vibration in the first living space became equal to or greater than the first set value. The "certain time" shall be set based on the time it takes for the vibration generated in the first living space to reach the second living space farthest from the first living space through the housing of the house 100. The "magnitude of vibration" is, similar to the magnitude of vibration in the first living space, a value related to vibration calculated based on the output signal from the vibration sensor 11 (for example, acceleration (m / s 2It may also be a value obtained by converting vibration into noise (noise level (dB)), and this value (level) may be the absolute value of the magnitude of vibration in a period until a certain time has elapsed since the magnitude of vibration in the first living space became equal to or greater than the first set value, or may be the amount of increase (relative value) from immediately before (for example, 1 to 5 seconds before) in that period.

[0034] <Second determination processing unit> The second determination processing unit 35 compares the magnitude of vibration in the specified second living space with a preset second set value, and determines whether the magnitude of the vibration is equal to or greater than the second set value.

[0035] <Warning processing unit> When the magnitude of vibration in the specified second living space becomes equal to or greater than the second set value, the warning processing unit 36 executes a process of giving a warning to the first living space (corresponding to the warning process). More specifically, the warning processing unit 36 identifies a living space affected by the impact sound generated in the first living space among the plurality of living spaces specified as the second living space, and identifies the floor on which the living space exists. Then, the warning processing unit 36 causes the warning device 13 to output information indicating the floor affected by the impact sound. Note that instead of causing the warning device 13 to output information indicating the floor affected by the impact sound, the warning processing unit 36 may cause the warning device 13 to output information indicating the living space affected by the impact sound.

[0036] <<Regarding the warning processing flow according to this embodiment>> Next, a warning processing flow using the above-described living environment management facility 10 will be described. The warning processing flow proceeds along the flow shown in FIG. 4. Note that the warning processing flow shown in FIG. 4 is merely an example, and new steps may be added without departing from the spirit of the present invention.

[0037] The living environment management device 10 is one of the electrical facilities used in the common areas of an apartment building. The warning processing flow starts, for example, when the housing provider (housing manufacturer) turns on the power to the electrical facilities in the common areas after the completion of the housing. In each step of the warning processing flow, the processor 12a of the computer constituting the processing device 12 executes the processing corresponding to each step. Note that the following explanation is based on the premise that in the housing 100 shown in FIG. 1, the living space 302 is the first living space that generates impact sound, and the living space 101 is a living space among the second living spaces where the magnitude of vibration is equal to or greater than the second set value.

[0038] In the warning processing flow, first, the processor 12a acquires the output signals from each vibration sensor 11 provided in each living space on each floor (1st to 4th floors) (S101). Next, the processor 12a compares the output signals at the same time point from each vibration sensor 11 on the floors above the lowest floor (2nd to 4th floors) (S102). At this time, the processor 12a uses the output signals from the vibration sensors 11 provided under the floors of each living space on the 2nd to 4th floors. Thereby, it is possible to measure the vibration of the floor directly impacted and to more appropriately detect the magnitude of the vibration.

[0039] Next, the processor 12a identifies the living space 302 where the vibration sensor 11 indicating the largest output signal among the compared output signals is provided as the first living space (S103). Next, the processor 12a identifies the magnitude of the vibration in the first living space based on the output signal from the vibration sensor 11 provided in the first living space, more specifically, the vibration sensor 11 provided under the floor of the living space 302 (S104). Next, the processor 12a compares the magnitude of the vibration in the identified first living space with a preset first set value, and determines whether or not the magnitude of the vibration is equal to or greater than the first set value (S105). If the magnitude of the vibration is less than the first set value, the processor 12a skips steps S106 to S110 and ends the warning processing flow.

[0040] On the one hand, when the magnitude of the vibration is equal to or greater than the first set value, the processor 12a identifies each living space on the floors below the first living space, more specifically, all the living spaces 101 to 103 and 201 to 203 on the first and second floors, as the second living space (S106). In other words, the processor 12a excludes each living space 301, 303 on the same floor (the third floor) as the first living space and each living space 401 to 403 on the floors above the first living space (the fourth floor) from the second living space.

[0041] Next, the processor 12a identifies the magnitude of the vibration in the second living space existing on the floors below the first living space (the first and second floors) based on the output signal from the vibration sensor 11 provided on the floor where the second living space exists, more specifically, the vibration sensor 11 provided in the ceiling space of the second living space. Note that by identifying the magnitude of the vibration based on the output signal from the vibration sensor 11 provided in the ceiling space, the vibration from the first living space (living space 302) located above can be detected more appropriately. Next, the processor 12a compares the magnitude of the vibration in the identified second living space with a preset second set value, and determines whether the magnitude of the vibration is equal to or greater than the second set value (S108).

[0042] If the magnitude of the vibration is less than the second set value in all the second living spaces, the processor 12a skips steps S109 to S110 and ends the warning process flow. On the other hand, when there is a living space in the second living space where the magnitude of vibration is equal to or greater than the second set value, the processor 12a identifies that living space as a living space affected by the impact sound generated in the first living space, and identifies the floor on which that living space is located (S109). In the example shown in FIG. 1, the processor 12a identifies the living space 101 as the living space affected by the impact sound, and identifies the first floor as the floor on which the living space 101 is located. After that, the processor 12a causes the warning device 13 to output information about the floor (the first floor) affected by the impact sound, and warns the occupants of the first living space (living space 302) (S110). For example, when the warning device 13 is a lighting device provided with lamps corresponding to each floor, the lamp corresponding to the first floor may be lit in red indicating that it has been affected by the impact sound, and the lamp corresponding to the second floor may be lit in blue indicating that it has not been affected by the impact sound.

[0043] When the series of processes up to the above are completed, the warning process flow ends. In this embodiment, as described above, since it is assumed that the output signal from the vibration sensor 11 is constantly acquired, this warning process flow is repeatedly executed each time the output signal from the vibration sensor 11 is acquired.

[0044] <<Regarding the effectiveness of this embodiment>> As described above, in the living environment management facility 10, the processing device 12 identifies the magnitude of vibration in the second living space based on the output signal from the vibration sensor 11 provided on the floor where the second living space is located. Therefore, even if it is not the second living space existing on the floor close to the first living space, as long as it is the second living space existing on the floor below the first living space, the magnitude of vibration can be appropriately identified. As a result, the influence of the impact sound on the second living space existing on the floor below the first living space can be appropriately confirmed.

[0045] Note that the range of influence of the impact sound generated in the first living space on the lower floors varies depending on the sound insulation structure of the housing 100. Therefore, the resident does not know what level of impact sound will not affect the surrounding living spaces, and there is a risk of being forced to live a life being overly concerned about impact sounds. Regarding this, according to the living environment management facility 10 of the present embodiment, since the influence of the impact sound on the second living space can be appropriately confirmed, the resident can live without being overly concerned about sounds.

[0046] Also, in the present embodiment, the impact sound accompanied by vibration generated in the first living space is transmitted to the second living space through the housing of the housing 100 and is generated as a vibration sound in the second living space. Regarding this, in the present embodiment, since the magnitude of the vibration in the second living space is specified by the vibration sensor 11, the generation of the vibration sound in the second living space can be appropriately confirmed.

[0047] Further, in the technology described in Patent Document 1 shown above, it is only possible to confirm the influence of the impact sound on the living space directly below the living space where the impact sound has occurred among the floors one floor below the living space where the impact sound has occurred, and it is not possible to confirm the influence of the impact sound on the living space located diagonally below the living space where the impact sound has occurred among the floors one floor below the living space where the impact sound has occurred. In contrast, in the living environment management facility 10 of the present embodiment, for the second living space existing on the floor below the first living space, since the magnitude of the vibration can be appropriately specified, it is possible to appropriately confirm that the impact sound has an impact even in the second living space located diagonally below the first living space on the floor one floor below the first living space.

[0048] Also, in the present embodiment, a vibration sensor 11 is provided in each of a plurality of living spaces including the first living space and the second living space, and the processing device 12 specifies the first living space from among the plurality of living spaces based on the output signals from the vibration sensors 11 provided in each of the plurality of living spaces in the first specifying process. In this way, in the living environment management facility 10, since the vibration sensors 11 are provided in each living space, it is possible to appropriately identify the first living space that generates impact sound from among the living spaces. Further, the processing device 12 can exclude, from the living spaces to be processed in the processes after the first specific processing, the other living spaces on the same floor as the first living space and the living spaces existing on the floors above the first living space, by identifying the first living space in the first specific processing. For this reason, the man-hours for data processing in the processing device 12 can be reduced. In particular, the more floors and living spaces there are in a house, the more effectively the man-hours for data processing can be reduced.

[0049] Also, in the present embodiment, the second living space includes the living spaces on the floors that are two or more floors below the first living space. Thereby, it is possible to appropriately confirm the influence of the impact sound on the living spaces on the floors that are two or more floors below the first living space. In other words, the living environment management facility 10 can appropriately confirm the influence of the impact sound on the second living space in a house with three or more floors.

[0050] <<Regarding Other Embodiments>> Up to this point, one embodiment of the living environment management facility of the present invention has been described. However, the above embodiment is merely an example for facilitating the understanding of the present invention and does not limit the present invention. That is, the present invention can be changed and improved without departing from its gist. Also, it goes without saying that the present invention includes its equivalents.

[0051] In the above embodiment, it is premised that the vibration sensors 11 are provided in each living space on each floor. However, the present invention is not limited to this, and at least one vibration sensor 11 may be provided on each floor. For example, even when only one vibration sensor 11 is provided on each floor, it is possible to confirm the floor where the impact sound accompanied by vibration occurs and the floors affected by the impact sound. As a result, it is possible to notify the residents of each living space on the floor that is the source of the impact sound of the information indicating the floors affected by the impact sound.

[0052] Alternatively, this warning process may be implemented using the living environment management device 10A shown in FIG. 5 instead of the living environment management device 10. The living environment management device 10A is provided with a sound sensor 14A, and the sound sensor 14A is provided in each living space that may correspond to the second living space, more specifically, in each living space on the floors below the top floor (floors 1 to 3 in FIG. 5). The sound sensor 14A converts sound into an electrical signal (output signal), and may be, for example, a MEMS (Micro Electro Mechanical Systems) microphone, a gamma microphone, a pin microphone, or a vocal microphone, etc., and its type and the presence or absence of directivity are not limited. The sound sensor 14A may be arranged adjacent to electrical equipment in the living space. For example, a MEMS microphone that forms the sound sensor 14A may be installed in a ceiling light provided on the ceiling. In this case, the power supplied to the ceiling light may also be supplied to the sound sensor 14A.

[0053] Next, the warning process flow using the living environment management device 10A shown in FIG. 5 will be described. The warning process flow proceeds along the flow shown in FIG. 6. Note that the warning process flow shown in FIG. 6 is merely an example, and new steps may be added without departing from the spirit of the present invention. Note that steps S201 to S208 of the warning process flow shown in FIG. 6 are the same as steps S101 to 108 of the warning process flow shown in FIG. 4, so the description thereof will be omitted. Also, the following description is based on the premise that in the house 100 shown in FIG. 5, the living space 302 is the first living space that generates impact sound, and the living spaces 101 and 203 are the living spaces among the second living spaces where the magnitude of vibration is equal to or greater than the second set value, and the living space 101 is the living space where the increase amount of the sound magnitude is equal to or greater than a predetermined value.

[0054] After the processor 12a executes each step of steps S201 to S208, when the magnitude of vibration in the second living space becomes equal to or greater than the second set value, the processor 12a executes a process (corresponding to the third specifying process) of specifying the increase amount of the sound magnitude in the second living space based on the output signal from the sound sensor 14A. "Sound volume" is, for example, the noise level (dB). "Increase amount of sound volume" means the increase amount of sound volume from immediately before that period (for example, 1 to 5 seconds before) until a certain time has elapsed since the magnitude of vibration in the first living space became equal to or greater than the first set value.

[0055] In the example shown in FIG. 5, the processor 12a identifies the living spaces 101 and 203 in which the magnitude of vibration is equal to or greater than the second set value among the plurality of living spaces 101 to 103 and 201 to 203 identified as the second living space, and based on the output signals from the sound sensors 14A provided in the identified living spaces 101 and 203, identifies the increase amount of sound volume in the living spaces 101 and 203.

[0056] Next, the processor 12a compares the increase amount of sound volume in the second living space (living spaces 101 and 203) where the magnitude of vibration is equal to or greater than the second set value with a preset predetermined value, and determines whether or not the increase amount is equal to or greater than the predetermined value (S209). If the increase amount of sound volume is less than the predetermined value in any of the living spaces 101 and 203, the processor 12a skips steps S210 to S211 and ends the warning process flow. On the other hand, if the increase amount of sound volume becomes equal to or greater than the predetermined value in at least one of the living spaces 101 and 203, the processor 12a identifies that living space as a living space affected by the impact sound generated in the first living space, and identifies the floor on which that living space exists (S210). In the example shown in FIG. 1, the processor 12a identifies the living space 101 as the living space affected by the impact sound among the living spaces 101 and 203, and identifies the first floor as the floor on which the living space 101 exists. Thereafter, the processor 12a outputs the information on the floor (first floor) affected by the impact sound to the warning device 13 to warn the occupants of the first living space (living space 302) (S211). The warning process flow ends when the series of processes up to this point are completed. Note that this warning process flow is repeatedly executed each time an output signal from the vibration sensor 11 is acquired.

[0057] As described above, the living environment management facility 10A includes a sound sensor 14A provided in the second living space. Further, when the magnitude of vibration in the specified second living space becomes equal to or greater than the second set value, the processing device 12 executes a third specifying process of specifying the increase amount of the sound magnitude in the second living space based on the output signal from the sound sensor 14A. Then, when the increase amount becomes equal to or greater than a predetermined value, the processing device 12 executes a warning process of giving a warning to the first living space. Even when the magnitude of vibration in the second living space is equal to or greater than the second set value, if noise other than the impact sound from the first living space is generated in the second living space, the degree of influence of the impact sound from the first living space is reduced. In this regard, in the case of the living environment management facility 10A, since it is possible to confirm the increase amount of the sound magnitude in the second living space when the impact sound is generated in the first living space, it is possible to appropriately confirm the influence of the impact sound from the first living space in the second living space.

[0058] For example, if the occupants of the second living space include children and noise is generated in the second living space due to the children running around when an impact sound is generated in the first living space, the increase amount of the sound magnitude in the second living space will be less than the predetermined value, and there will be no need to give a warning to the first living space. On the other hand, for example, if the occupant of the second living space is a single person with a night shift job and is sleeping when an impact sound is generated in the first living space, the increase amount of the sound magnitude in the second living space will be equal to or greater than the predetermined value, and a warning will be given to the first living space. Thus, in the living environment management facility 10A, it is possible to appropriately confirm the influence of the impact sound on the second living space according to the noise situation in the second living space.
