[0021] First, the hardware configuration of a seismic sensor according to an embodiment will be described with reference to FIG. 1. FIG. 1 is a diagram showing an example of the hardware configuration of a seismic sensor according to an embodiment of the present invention. The seismic sensor 10-1 shown in FIG. 1 is, for example, a seismic relay, a seismic breaker, or a seismic outlet, and is installed in a building such as a house. The seismic relay is a device that automatically shuts off a main earth leakage breaker when seismic motion is detected. The seismic breaker is a device that automatically shuts off a breaker attached to a distribution board and stops the supply of power when seismic motion is detected. The seismic outlet is a receptacle that has a mechanism that cuts off the supply of power to the plug socket when seismic motion is detected. Furthermore, since the seismic sensor 10-1 is included in the building's electrical system, it can operate by receiving power from the electrical system.

[0022] As shown in FIG. 1, seismic sensor 10-1 includes processor 11-1, main memory 12-1, communication interface 13-1, auxiliary memory 14-1, sensor 15-1, and bus 16-1. Similarly, seismic sensor 10-2 includes processor 11-2, main memory 12-2, communication interface 13-2, auxiliary memory 14-2, sensor 15-2, and bus 16-2. Furthermore, seismic sensor 10-k (k: an integer greater than or equal to 2) includes processor 11-k, main memory 12-k, communication interface 13-k, auxiliary memory 14-k, sensor 15-k, and bus 16-k. In the explanation of this embodiment, seismic sensor 10-1 will be used as an example, but the same applies to seismic sensors 10-2, ..., and seismic sensor 10-k.

[0023] The processor 11-1 is, for example, a CPU (Central Processing Unit), which reads and executes a seismic program to realize each function of the seismic sensor 10-1. The processor 11-1 may also read and execute programs other than the seismic program to realize functions necessary to realize each function of the seismic sensor 10-1.

[0024] The main storage device 12-1 is, for example, a RAM (Random Access Memory), and stores in advance a seismic sensing program and other programs that are read and executed by the processor 11-1.

[0025] The communication interface 13-1 is an interface circuit for communicating with the building diagnosis device 20 via the network NW shown in Fig. 1. The communication interface 13-1 may also communicate with devices other than the building diagnosis device 20. Examples of such devices include at least one of the seismic sensors 10-2, ... and 10-k. The network NW may be, for example, a wide area network (WAN), a local area network (LAN), the internet, or an intranet.

[0026] The auxiliary storage device 14-1 is, for example, a hard disk drive (HDD), a solid state drive (SSD), a flash memory, or a read only memory (ROM).

[0027] The sensor 15-1 measures physical quantities related to seismic motion and generates physical quantity data indicating the physical quantities related to seismic motion. For example, the sensor 15-1 is an acceleration sensor that measures the acceleration of at least a part of a building in at least one of the X, Y, and Z directions due to seismic motion. The X and Y directions are, for example, directions substantially parallel to the floor surface of the building and intersect with each other. The Z direction is, for example, a direction substantially perpendicular to the floor surface of the building.

[0028] FIG. 2 is a diagram showing an example of the results of measuring the change over time in acceleration related to seismic motion using a sensor according to an embodiment of the present invention. The horizontal axis of FIG. 2 represents time. The vertical axis of FIG. 2 represents acceleration due to seismic motion. The waveform shown by the dashed line in FIG. 2 represents the change over time in acceleration in the X direction. The waveform shown by the solid line in FIG. 2 represents the change over time in acceleration in the Y direction. The waveform shown by the dashed line in FIG. 2 represents the change over time in acceleration in the Z direction. Sensor 15-1, for example, measures the change over time in acceleration shown in FIG. 2 and generates physical quantity data indicating the measurement results of acceleration at each time.

[0029] The bus 16-1 connects the processor 11-1, the main storage device 12-1, the communication interface 13-1, the auxiliary storage device 14-1, and the sensor 15-1 in a manner that allows data communication between them.

[0030] Next, the hardware configuration of a building diagnosis device according to an embodiment will be described with reference to Fig. 3. Fig. 3 is a diagram showing an example of the hardware configuration of a building diagnosis device according to an embodiment of the present invention. The building diagnosis device 20 shown in Fig. 3 is, for example, a server, a computer, a smartphone, or a tablet. As shown in Fig. 3, the building diagnosis device 20 includes a processor 21, a main memory device 22, a communication interface 23, an auxiliary memory device 24, an input / output device 25, and a bus 26.

[0031] The processor 21 is, for example, a CPU, and reads and executes the building diagnosis program to realize each function of the building diagnosis device 20. The processor 21 may also read and execute a program other than the building diagnosis program to realize a function required to realize each function of the building diagnosis device 20.

[0032] The main storage device 22 is, for example, a RAM, and stores in advance a building diagnosis program and other programs that are read and executed by the processor 21.

[0033] The communication interface 23 is an interface circuit for communicating with at least one of the seismic sensors 20-1, . . . and 20-k via the network NW shown in FIG.

[0034] The auxiliary storage device 24 is, for example, a hard disk drive, a solid state drive, a flash memory, or a ROM.

[0035] The input / output device 25 is, for example, an input / output port. The input / output device 25 is connected to, for example, a keyboard and a mouse used to operate the building diagnosis device 20 and a display that displays a graphical user interface (GUI) of the building diagnosis device 20.

[0036] The bus 26 connects the processor 21, the main memory device 22, the communication interface 23, the auxiliary memory device 24, and the input / output device 25 in a manner that allows data communication between them.

[0037] Next, the software configuration of the seismic sensor according to the embodiment will be described with reference to Figure 4. Figure 4 is a diagram showing an example of the software configuration of the seismic sensor according to the embodiment of the present invention. The seismic sensor 10-1 reads and executes a seismic program using, for example, the processor 11-1. As a result, the seismic sensor 10-1 realizes the determination unit 101-1, recording unit 102-1, and transmission unit 103-1 shown in Figure 4.

[0038] The determination unit 101-1 determines whether the physical quantity indicated by the physical quantity data exceeds a predetermined first threshold. When the determination unit 102-1 determines that the physical quantity indicated by the physical quantity data exceeds the predetermined first threshold, the recording unit 102-1 records, on a recording medium, physical quantity data indicating physical quantities measured by a sensor after the physical quantity indicated by the physical quantity data exceeded the predetermined first threshold. Furthermore, when the determination unit 102-1 determines that the physical quantity indicated by the physical quantity data exceeds the predetermined first threshold, the recording unit 102-1 may record, on a recording medium, physical quantity data indicating physical quantities measured by a sensor before the physical quantity indicated by the physical quantity data exceeded the predetermined first threshold. The recording medium may be mounted on the seismic sensor 10-1 or may be provided externally to the seismic sensor 10-1. The transmission unit 103-1 transmits the physical quantity data recorded on the recording medium to the building diagnosis device 20.

[0039] Next, the software configuration of the building diagnosis device according to the embodiment will be described with reference to Fig. 5. Fig. 5 is a diagram showing an example of the software configuration of the building diagnosis device according to the embodiment of the present invention. The building diagnosis device 20 reads and executes a building diagnosis program using, for example, the processor 21. As a result, the building diagnosis device 20 realizes the receiving unit 201, the diagnosis unit 202, and the transmitting unit 203 shown in Fig. 5.

[0040] The receiving unit 201 receives from the seismic sensor 10-1 physical quantity data indicating the physical quantity measured by the sensor 15-1 after the physical quantity measured by the sensor included in the seismic sensor 10-1 exceeds a predetermined first threshold. Similarly, the receiving unit 201 receives from the seismic sensor 10-2 physical quantity data indicating the physical quantity measured by the sensor 15-2 after the physical quantity measured by the sensor included in the seismic sensor 10-2 exceeds a predetermined first threshold. Furthermore, the receiving unit 201 receives from the seismic sensor 10-k physical quantity data indicating the physical quantity measured by the sensor 15-k after the physical quantity measured by the sensor included in the seismic sensor 10-k exceeds a predetermined first threshold.

[0041] The receiving unit 201 may receive from the seismic sensor 10-1 physical quantity data indicating the physical quantity measured by the sensor 15-1 before the physical quantity measured by the sensor 15-1 exceeded a predetermined first threshold. Similarly, the receiving unit 201 may receive from the seismic sensor 10-2 physical quantity data indicating the physical quantity measured by the sensor 15-2 before the physical quantity measured by the sensor 15-2 exceeded a predetermined first threshold. Furthermore, the receiving unit 201 may receive from the seismic sensor 10-k physical quantity data indicating the physical quantity measured by the sensor 15-k before the physical quantity measured by the sensor 15-k exceeded a predetermined first threshold.

[0042] The receiving unit 201 may further receive at least one of physical quantity data indicating the physical quantity measured by the sensor 15-1 after the physical quantity measured by the sensor 15-1 becomes less than a predetermined second threshold. Similarly, the receiving unit 201 may further receive at least one of physical quantity data indicating the physical quantity measured by the sensor 15-2 after the physical quantity measured by the sensor 15-2 becomes less than a predetermined second threshold. Furthermore, the receiving unit 201 may further receive at least one of physical quantity data indicating the physical quantity measured by the sensor 15-k after the physical quantity measured by the sensor 15-k becomes less than a predetermined second threshold. Note that these second thresholds may be equal to or different from the first threshold.

[0043] The receiving unit 201 also receives earthquake resistance performance data indicating the earthquake resistance of the building in which the earthquake sensors 10-1, ... and 10-k are installed. The earthquake resistance here is estimated from, for example, the structure of the building, the age of the building, etc.

[0044] The diagnosing unit 202 diagnoses the degree of damage to the building based on the physical quantity data and the seismic performance data, and generates diagnostic data indicating the results of diagnosing the degree of damage to the building. For example, the diagnosing unit 202 generates the diagnostic data based on the frequency characteristics of the physical quantities indicated by the physical quantity data. The diagnosing unit 202 applies a fast Fourier transform to the change in acceleration over time shown in FIG. 2 to derive the frequency characteristics of acceleration shown in FIG. 6.

[0045] FIG. 6 is a diagram showing an example of the results of analyzing, using a fast Fourier transform, the results of measuring the change over time in acceleration related to seismic motion using a sensor according to an embodiment of the present invention. The horizontal axis of FIG. 6 represents frequency. The vertical axis of FIG. 6 represents acceleration due to seismic motion. The waveform shown by the dashed line in FIG. 6 represents the frequency characteristics of acceleration in the X direction. The waveform shown by the dashed line in FIG. 6 represents the frequency characteristics of acceleration in the Y direction. The waveform shown by the two-dot chain line in FIG. 6 represents the frequency characteristics of acceleration in the Z direction. The waveform shown by the solid line in FIG. 6 represents the frequency characteristics of acceleration obtained by combining the acceleration in the X direction, the acceleration in the Y direction, and the acceleration in the Z direction. For example, the diagnosing unit 202 diagnoses the degree of damage to the building using at least a portion of the frequency characteristics of acceleration shown in FIG. 6 and generates diagnosis data indicating the results of diagnosing the degree of damage to the building.

[0046] Furthermore, the diagnosing unit 202 diagnoses the degree of inclination of the building based on the physical quantity data and the seismic performance data, and generates diagnosis data indicating the result of diagnosing the degree of inclination of the building. The physical quantity data referred to here is physical quantity data indicating physical quantities measured by the sensor 15-1, etc. before the physical quantities measured by the sensor 15-1, etc. exceeded a predetermined first threshold. Alternatively, the physical quantity data referred to here is physical quantity data indicating physical quantities measured by the sensor 15-1 after the physical quantities measured by the sensor 15-1 became less than a predetermined second threshold. For example, the diagnosing unit 202 diagnoses the degree of inclination of the building based on physical quantity data indicating changes over time in acceleration during period T1 or period T3 shown in FIG. 7.

[0047] FIG. 7 is a diagram showing an example of acceleration measured by sensors before earthquake motion occurs, during the period when the earthquake motion occurs, and after the earthquake motion has subsided, according to an embodiment of the present invention. The horizontal axis of FIG. 7 represents time. The vertical axis of FIG. 7 represents acceleration due to building tilt. Period T1 shown in FIG. 7 is an example of a period before the physical quantity measured by sensor 15-1, etc. exceeds a predetermined first threshold. Period T2 shown in FIG. 7 is an example of a period from the time when the physical quantity measured by sensor 15-1, etc. exceeds the predetermined first threshold to the time before the physical quantity measured by sensor 15-1 becomes less than a predetermined second threshold. Period T3 shown in FIG. 7 is an example of a period after the time when the physical quantity measured by sensor 15-1 becomes less than the predetermined second threshold.

[0048] The waveform shown by the dashed line in Figure 7 shows the change over time in acceleration in the X direction due to the tilt of the building. The waveform shown by the dashed line in Figure 7 shows the change over time in acceleration in the Y direction due to the tilt of the building. The waveform shown by the two-dot chain line in Figure 7 shows the change over time in acceleration in the Z direction due to the tilt of the building.

[0049] For example, the diagnosis unit 202 calculates the angle of the building in each of the periods T1, T2, and T3 based on at least one of the acceleration in the X direction, the acceleration in the Y direction, and the acceleration in the Z direction. If the angle exceeds a predetermined angle, the diagnosis unit 202 diagnoses that the building is leaning to the extent that it may collapse, and generates diagnosis data indicating that the building is leaning to the extent that it may collapse.

[0050] Furthermore, the diagnosis unit 202 may determine the priority of at least one of building inspection and repair based on the physical quantity data and the seismic performance data, and generate diagnosis data indicating the priority of at least one of building inspection and repair. Such diagnosis data is transmitted to, for example, a terminal such as a smartphone used by a building manager, or a server, computer, or other terminal used by a business providing building support to the building manager, and is used to determine a response when an earthquake occurs.

[0051] The transmission unit 203 transmits the diagnostic data. For example, the transmission unit 203 transmits the diagnostic data to a device other than the building diagnostic device 20. The device other than the building diagnostic device 20 is, for example, a terminal such as a smartphone used by the manager who manages the building, or a terminal such as a server or computer used by a business that provides support related to the building to the manager of the building.

[0052] Next, an example of processing executed by the seismic sensor 10-1 according to the embodiment will be described with reference to Fig. 8. Fig. 8 is a flowchart showing an example of processing executed by the seismic sensor according to the embodiment of the present invention. Note that the seismic sensor 10-2, ... and seismic sensor 10-k also execute processing similar to that shown in Fig. 8.

[0053] In step S81, the determination unit 101-1 determines whether the physical quantity indicated by the physical quantity data is It is determined whether the physical quantity indicated by the physical quantity data exceeds the predetermined first threshold. If the determination unit 101-1 determines that the physical quantity indicated by the physical quantity data exceeds the predetermined first threshold (step S81: YES), the process proceeds to step S82. On the other hand, if the determination unit 101-1 determines that the physical quantity indicated by the physical quantity data exceeds the predetermined first threshold (step S81: NO), the determination unit 101-1 waits until it determines that the physical quantity indicated by the physical quantity data exceeds the predetermined first threshold.

[0054] In step S82, the recording unit 102-1 records the physical quantity data on a recording medium.

[0055] In step S83, the transmitting unit 103-1 transmits the physical quantity data recorded on the recording medium.

[0056] Next, an example of processing executed by the building diagnosis device 20 according to the embodiment will be described with reference to Fig. 9. Fig. 9 is a flowchart showing an example of processing executed by the building diagnosis device according to the embodiment of the present invention.

[0057] In step S91, the receiving unit 201 receives the physical quantity data and the seismic performance data.

[0058] In step S92, the diagnosing unit 202 diagnoses the degree of damage to the building based on the physical quantity data and the seismic performance data, and generates diagnosis data indicating the results of diagnosing the degree of damage to the building.

[0059] In step S93, the transmitting unit 203 transmits the diagnostic data.

[0060] The seismic sensing device, building diagnosis device, seismic sensing program, building diagnosis program, seismic sensing method, and building diagnosis method according to the embodiments have been described above.

[0061] The seismic sensor 10-1 includes a sensor 15-1, a determination unit 101-1, and a recording unit 102-1. The sensor 15-1 measures physical quantities related to seismic motion and generates physical quantity data indicating the physical quantities related to seismic motion. The determination unit 101-1 determines whether the physical quantity indicated by the physical quantity data exceeds a predetermined first threshold. If it is determined that the physical quantity indicated by the physical quantity data exceeds the predetermined first threshold, the recording unit 102-1 records the physical quantity data indicating the physical quantities measured by the sensor after the physical quantity indicated by the physical quantity data exceeded the predetermined first threshold on a recording medium. Furthermore, since the seismic sensor 10-1 is included in the building's electrical system, it can operate by receiving power from the electrical system. Furthermore, the same applies to the seismic sensors 10-2, ..., and 10-k.

[0062] As a result, the seismic sensors 10-1, ..., and 10-k can operate with a stable supply of power from the building's electrical system, and can reliably execute processes such as generating physical quantity data and recording on a recording medium the physical quantity data indicating the physical quantity measured by the sensor after the physical quantity indicated by the physical quantity data exceeds a predetermined first threshold.

[0063] Furthermore, when it is determined that the physical quantity indicated by the physical quantity data exceeds a predetermined first threshold, the recording unit 102-1 records, on the recording medium, physical quantity data indicating the physical quantity measured by the sensor before the physical quantity indicated by the physical quantity data exceeded the predetermined first threshold. This also applies to the recording units 102-2, ..., and 102-k.

[0064] Therefore, the seismic sensor 10-1, ... and the seismic sensor 10-k can reliably perform processes such as recording onto a recording medium physical quantity data indicating the physical quantity measured by the sensor before the physical quantity indicated by the physical quantity data exceeds a predetermined first threshold value.

[0065] The transmitting unit 103-1 transmits the physical quantity data recorded on the recording medium, and the same applies to the transmitting units 103-2, ..., and 103...k.

[0066] As a result, the seismic sensors 10-1, ... and 10-k can make it possible to utilize the physical quantities recorded on the recording medium using other devices.

[0067] The building diagnosis device 20 includes a receiving unit 201 and a diagnosing unit 202. The receiving unit 201 receives physical quantity data indicating the physical quantity measured by the sensor 15-1 after the physical quantity measured by the sensor 15-1 exceeds a predetermined first threshold, and seismic performance data indicating the seismic performance of the building in which the seismic sensor 10-1 is installed. The diagnosing unit 202 diagnoses the degree of damage to the building based on the physical quantity data and the seismic performance data, and generates diagnosis data indicating the results of the diagnosis of the degree of damage to the building.

[0068] This allows the building diagnostic device 20 to reliably generate diagnostic data using seismic performance data and physical quantity data generated by operating while receiving a stable supply of power from the building's electrical system.

[0069] Furthermore, the diagnosis unit 202 generates diagnosis data based on the frequency characteristics of the physical quantity indicated by the physical quantity data.

[0070] This allows the building diagnosis device 20 to generate diagnosis data that indicates the results of a more accurate diagnosis of the extent of damage to the building.

[0071] The receiving unit 201 further receives at least one of physical quantity data indicating the physical quantity measured by the sensor 15-1 before the physical quantity measured by the sensor 15-1 exceeded a predetermined first threshold and physical quantity data indicating the physical quantity measured by the sensor 15-1 after the physical quantity measured by the sensor 15-1 became less than a predetermined second threshold. The diagnosing unit 202 diagnoses the degree of inclination of the building based on the seismic performance data and at least one of the physical quantity data indicating the physical quantity measured by the sensor 15-1 before the physical quantity measured by the sensor 15-1 exceeded the predetermined first threshold and the physical quantity data indicating the physical quantity measured by the sensor 15-1 after the physical quantity measured by the sensor 15-1 became less than the predetermined second threshold, and the seismic performance data, and generates diagnosis data indicating the results of the diagnosis of the degree of inclination of the building.

[0072] As a result, the building diagnostic device 20 operates by receiving a stable supply of power from the building's electrical system, and can reliably generate diagnostic data relating to the degree of tilt of the building.

[0073] Furthermore, the transmitting unit 203 transmits the diagnostic data.

[0074] This allows the building diagnostic device 20 to make the diagnostic data available for use with other devices.

[0075] Furthermore, the diagnosing unit 202 determines the priority of at least one of the inspection and repair of the building based on the physical quantity data and the seismic performance data, and generates diagnosis data indicating the priority of at least one of the inspection and repair of the building.

[0076] This allows the building diagnostic device 20 to generate diagnostic data that can present the priority of at least one of building inspection and repair.

[0077] In the above-described embodiment, the sensors 15-1, ..., and 15-k are acceleration sensors, but the present invention is not limited to this. At least one of the sensors 15-1, ..., and 15-k may be, for example, a velocity sensor or a displacement sensor. The velocity sensor measures the velocity of at least a part of the building in at least one of the X, Y, and Z directions caused by seismic motion. In this case, the physical quantity indicated by the physical quantity data is the velocity of at least a part of the building. The displacement sensor measures the displacement of at least a part of the building in at least one of the X, Y, and Z directions caused by seismic motion. In this case, the physical quantity indicated by the physical quantity data is the displacement of at least a part of the building.

[0078] In addition, in the above-described embodiment, an example was given in which the functions provided by the seismic sensor device 10-1 etc. shown in Figure 3 are realized by a processor 11-1 etc. that reads and executes a seismic program, but this is not limited to this.
