[0004] However, with the technology described in Patent Document 1, there is a risk that smoke will spread from the room where the fire is suspected to have broken out to other rooms. Since the majority of deaths from fires are due to poisoning caused by gases contained in the smoke, it is extremely important from a safety perspective to prevent smoke from filling the building. Furthermore, it is desirable to prevent gas from filling the building not only in the event of an actual fire, but also in the event of a gas leak.

[0005] In consideration of the above facts, the present invention aims to provide a building information processing device, a building information processing method, and a building information processing program that can prevent gas and smoke from filling a building in the event of a gas leak or fire. [Means for solving the problem]

[0007] According to the first aspect of the present invention, an acquisition unit acquires information about gas concentration from a sensor installed in a room of a building. Furthermore, a determination unit determines whether the gas concentration is equal to or greater than a reference value based on the gas concentration acquired by the acquisition unit. Furthermore, if the determination unit determines that the gas concentration is equal to or greater than the reference value, control is performed to suppress the inflow of air from one room to another. This prevents high-concentration gas from the room from inflowing into another room.

[0008] The building information processing device according to the second aspect is an invention described in claim 1, and has a first-class ventilation outlet control unit that closes the first-class ventilation outlet provided in the other room when the judgment unit determines that the gas concentration is equal to or greater than a reference value.

[0009] According to the second aspect of the present invention, when the determination unit determines that the gas concentration is equal to or greater than the reference value, the first-class ventilation outlet control unit closes the first-class ventilation outlet provided in the other room, thereby preventing air circulating inside the building by the first-class ventilation from flowing into the other room through the first-class ventilation outlet provided in the other room.

[0012] The building information processing device according to the fourth aspect is an invention as described in claim 1, and has an internal fixture control unit that closes internal fixtures installed inside the building when the judgment unit determines that the gas concentration is above a reference value.

[0013] According to the fourth aspect of the present invention, when the determination unit determines that the gas concentration is equal to or greater than the reference value, the interior fixture control unit closes interior fixtures such as doors and interior windows installed inside the building, thereby preventing air from moving from one room to another through openings in the interior fixtures.

[0014] The building information processing device according to the fifth aspect is an invention as described in claim 1, and has a third-class ventilation outlet control unit that controls a third-class ventilation outlet of the building to exhaust air to the outside of the building when the judgment unit determines that the gas concentration is equal to or greater than a reference value.

[0015] According to the fifth aspect of the present invention, when the determination unit determines that the gas concentration is equal to or greater than the reference value, the third-class ventilation opening control unit controls the third-class ventilation opening of the building to exhaust air to the outside of the building, thereby exhausting the high-concentration gas to the outside of the building.

[0016] A sixth aspect of the information processing method for buildings involves a computer acquiring information regarding gas concentration from a sensor installed inside a room of a building, determining based on the acquired gas concentration whether the gas concentration is above a reference value, and if it is determined that the gas concentration is above the reference value, executing a process to suppress the flow of air from the room to another room.

[0028] Hereinafter, a building information processing device 10 according to one embodiment of the present invention will be described with reference to FIGS.

[0029] As shown in FIG. 1, a building information processing device 10 according to this embodiment is installed in a building 12 and serves as a controller for a Home Energy Management System (HEMS). The building 12 is, for example, a house capable of first-class ventilation and central air conditioning, and includes a kitchen, bathroom, toilet, and multiple living rooms (not shown). Each room is provided with a first-class ventilation outlet 30 for blowing first-class ventilation air into the room, and a central air conditioning outlet 32 ​​for blowing central air-conditioning air into the room. The kitchen, bathroom, and toilet are respectively provided with a kitchen exhaust fan 36, a bathroom exhaust fan 38, and a toilet exhaust fan 40, each serving as a third-class ventilation outlet. The kitchen is equipped with a gas stove (not shown) and a gas valve 44.

[0030] Furthermore, multiple sensors 28 for measuring gas concentrations are installed within the building 12. One of the sensors 28 is located in the kitchen. Additionally, multiple alarms 42 are installed within the building 12.

[0031] The information processing device 10 includes a CPU 14, a ROM 16, a RAM 18, a storage 20, a communication interface (communication I / F) 22, and an input / output interface (input / output I / F) 24. Each component is connected to each other via an internal bus 26 so as to be able to communicate with each other.

[0032] The CPU 14 is a central processing unit that executes various programs and controls each component. That is, the CPU 14 reads programs from the ROM 16 or storage 20 and executes the programs using the RAM 18 as a work area. The CPU 14 also controls the above components and performs various arithmetic operations in accordance with the programs stored in the ROM 16 or storage 20.

[0033] The ROM 16 stores various programs and various data. The RAM 18 temporarily stores programs or data as a working area. The storage 20 is configured by an HDD (Hard Disk Drive) or an SSD (Solid State Drive), and is a non-temporary recording medium that stores various programs including an operating system and various data. In this embodiment, the ROM 16 or the storage 20 stores programs for performing various processes.

[0034] The communication I / F 22 is an interface for the information processing device 10 to communicate with the outside, such as a fire department, etc. For example, standards such as Ethernet (registered trademark), LTE (Long Term Evolution), FDDI (Fiber Distributed Data Interface), Wi-Fi (registered trademark), Bluetooth (registered trademark), and NFC (Near field communication) are used.

[0035] The input / output I / F 24 is electrically connected to a plurality of sensors 28, a plurality of alarms 42, a kitchen gas valve 44, a kitchen exhaust fan 36, a bathroom exhaust fan 38, a toilet exhaust fan 40, a first-class ventilation outlet 30 provided in each room, a central air conditioning outlet 32 ​​provided in each room, a plurality of interior fittings 34 such as doors and interior windows provided inside the building 12, a distribution board 46, and lighting 48 in each room.

[0036] (Functional configuration of information processing device 10) The information processing device 10 uses the above hardware resources to realize various functions. The functional configuration realized by the information processing device 10 will be described with reference to FIG.

[0037] 2, the information processing device 10 is configured to include, as functional components, an acquisition unit 50, a determination unit 52, a first-class ventilation outlet control unit 54, a central air-conditioning outlet control unit 56, an interior fittings control unit 58, a third-class ventilation opening control unit 60, a lighting control unit 62, an alarm unit 64, a gas valve control unit 66, a power cutoff unit 68, and a notification unit 70. Each functional component is realized by the CPU 14 reading and executing a program stored in the ROM 16 or storage 20.

[0038] The acquisition unit 50 has a function of acquiring information about gas concentrations from sensors 28 installed in rooms of the building 12 .

[0039] The determining unit 52 has a function of determining, based on the gas concentration acquired by the acquiring unit 50, whether or not the gas concentration is equal to or greater than a reference value.

[0040] The first-class ventilation outlet control unit 54 has the function of closing the first-class ventilation outlets 30 provided in each room when the judgment unit 52 judges that the gas concentration is above the reference value, and performing control to suppress the inflow of air from rooms with high gas concentrations to other rooms through first-class ventilation.

[0041] The central air conditioning outlet control unit 56 has the function of closing the central air conditioning outlets 32 installed in each room when the judgment unit 52 determines that the gas concentration is above the standard value, and performing control to suppress the inflow of air from rooms with high gas concentrations to other rooms through the central air conditioning.

[0042] The internal fittings control unit 58 has the function of closing the internal fittings 34 when the judgment unit 52 judges that the gas concentration is above the reference value, and controlling the flow of air from a room with a high gas concentration to other rooms through the openings in the fittings.

[0043] The third type ventilation outlet control unit 60 has the function of operating the kitchen ventilation fan 36, bathroom ventilation fan 38, and toilet ventilation fan 40 at full power and exhausting air outside the building 12 when the judgment unit 52 determines that the carbon monoxide concentration is above the standard value.

[0044] The lighting control unit 62 has a function of turning on all the lights 48 in the building 12 when the determining unit 52 determines that the gas concentration is equal to or greater than the reference value.

[0045] The notification unit 64 has the function of controlling multiple alarm devices 42 to emit alarm sounds and voices from the alarm devices 42 and issue various notifications to people inside the building 12 when the judgment unit 52 determines that the gas concentration is above the reference value.

[0046] The gas valve control unit 66 has a function of closing the gas valve 44 when the determination unit 52 determines that the gas concentration is equal to or greater than the reference value.

[0047] The power cutoff unit 68 has a function of cutting off power to components other than the lighting 48, the sensor 28, and the information processing device 10 when the determining unit 52 determines that the gas concentration is equal to or greater than the reference value.

[0048] The reporting unit 70 is configured to automatically call 119 to the fire department when the determining unit 52 determines that the gas concentration is equal to or greater than the reference value.

[0049] (action) Next, the operation of this embodiment will be described.

[0050] An example of processing executed by the building information processing device 10 of this embodiment will be described with reference to the flowchart shown in FIG.

[0051] The flowchart in FIG. 3 shows the flow of processing after the acquisition unit 50 acquires information about gas concentrations from the sensor 28 in the kitchen.

[0052] In step S100 of FIG. 3, the CPU 14 of the information processing device 10 determines, by the function of the determination unit 52, whether or not the gas concentration acquired by the acquisition unit 50 is equal to or greater than 1 / 100 of the lower explosion limit concentration.

[0053] If the CPU 14 determines in step S100 that the gas concentration is not 1 / 100 or more of the lower explosion limit concentration, the process ends. On the other hand, if the CPU 14 determines in step S100 that the gas concentration is 1 / 100 or more of the lower explosion limit concentration, the CPU 14 turns on the kitchen exhaust fan 36 in step S102 using the function of the third-class ventilation opening control unit 60.

[0054] Furthermore, in step S104, the CPU 14 issues a first gas leak alert from the alarm device 42 using the function of the alert unit 64. As one example, this first gas leak alert includes an audible alarm, as well as a voice alerting the user that there is a risk of a gas leak in the kitchen and a voice urging the user to check the gas main valve and the gas stove switch. This allows people in the building 12 to recognize that there is a risk of a gas leak in the kitchen, and allows them to go and check the gas main valve and the gas stove switch.

[0055] Here, although not shown, the CPU 14 again acquires information on the gas concentration from the acquisition unit 50.

[0056] Then, in step S106, the CPU 14 determines, by the function of the determination unit 52, whether or not the gas concentration newly acquired by the acquisition unit 50 is equal to or greater than the lower explosion limit concentration.

[0057] If the CPU 14 determines in step S106 that the gas concentration is not equal to or greater than the lower explosion limit concentration, the process returns to step S100.

[0058] On the other hand, if the CPU 14 determines in step S106 that the gas concentration is equal to or higher than the lower explosion limit concentration, in step S108, the CPU 14 closes the first-class ventilation outlets 30 provided in each room by the function of the first-class ventilation outlet control unit 54. This prevents gas leaking in the kitchen from being diffused to other rooms by the first-class ventilation.

[0059] Furthermore, in step S108, CPU 14 closes central air-conditioning outlet 32 ​​provided in each room using the function of central air-conditioning outlet control unit 56. This prevents gas leaking in the kitchen from being diffused to other rooms by the central air-conditioning.

[0060] Furthermore, in step S108, the CPU 14 closes the internal fittings 34 using the function of the internal fitting control unit 58. This prevents gas leaking in the kitchen from diffusing to other rooms through openings in doors and interior windows.

[0061] Here, in step S108, the interior fitting control unit 58 either leaves the interior fitting 34 unlocked, or, if the interior fitting 34 is locked, unlocks the interior fitting 34. This makes it possible to suppress the movement of gas while preventing people in the building 12 from being delayed in evacuating due to unlocking the interior fitting 34.

[0062] Furthermore, in step S110, the CPU 14 issues a second gas leak alert from the alarm 42 using the function of the alert unit 64. As one example, this second gas leak alert alerts the user that there is a risk of explosion due to the gas leak and that open flames are strictly prohibited, and an audio message urging evacuation is played from the alarm 42. This allows people in the building 12 to recognize the risk of explosion, avoid open flames, and evacuate quickly.

[0063] Furthermore, in step S112, the CPU 14 closes the gas valve 44 using the function of the gas valve control unit 66. This makes it possible to prevent further gas leakage.

[0064] Furthermore, in step S114, the CPU 14 controls the distribution board 46 by using the function of the power cutoff unit 68 to cut off power to all components except the lights 48, the sensors 28, and the information processing device 10. This prevents a fire caused by an electrical leakage.

[0065] Next, another example of the processing executed by the building information processing device 10 of this embodiment will be described with reference to FIG.

[0066] The flowchart in FIG. 4 shows the flow of processing after the acquisition unit 50 acquires information about the carbon monoxide (CO) concentration from the sensor .

[0067] In step S200 of FIG. 4, the CPU 14 of the information processing device 10 determines, by the function of the determination unit 52, whether or not the CO concentration acquired by the acquisition unit 50 is 1 ppm or more.

[0068] If the CPU 14 determines in step S200 that the CO concentration is not 1 ppm or higher, it ends the process. On the other hand, if the CPU 14 determines in step S200 that the CO concentration is 1 ppm or higher, it uses the function of the lighting control unit 62 to turn on all the lights 48 in the building 12 in step S202. This makes it easier for people in the building 12 to visually confirm the evacuation route when evacuating. Therefore, people in the building 12 can evacuate quickly.

[0069] Furthermore, in step S204, CPU 14 uses the function of third type ventilation opening control section 60 to turn on kitchen ventilation fan 36, bathroom ventilation fan 38, and toilet ventilation fan 40.

[0070] Furthermore, in step S206, the CPU 14 closes the first-class ventilation air outlets 30 provided in each room by the function of the first-class ventilation air outlet control unit 54. This prevents carbon monoxide from diffusing from a room with a high CO concentration to other rooms due to the first-class ventilation.

[0071] Furthermore, in step S206, the CPU 14 closes the central air-conditioning outlet 32 ​​provided in each room by the function of the central air-conditioning outlet control unit 56. This prevents carbon monoxide from being diffused from a room with a high CO concentration to other rooms due to central air-conditioning.

[0072] Furthermore, in step S206, the CPU 14 closes the internal fittings 34 using the function of the internal fitting control unit 58. This prevents carbon monoxide from diffusing from a room with a high CO concentration to another room through the opening of a door or an interior window.

[0073] Here, in step S206, the interior fitting control unit 58 either leaves the interior fitting 34 unlocked, or, if the interior fitting 34 is locked, unlocks the interior fitting 34. This makes it possible to suppress the movement of carbon monoxide while preventing people in the building 12 from being delayed in evacuating due to unlocking the interior fitting 34.

[0074] Furthermore, in step S208, the CPU 14 controls the distribution board 46 by using the function of the power cutoff unit 68 to cut off power to all components other than the lighting 48, the sensor 28, and the information processing device 10. This prevents a fire caused by an electrical leakage.

[0075] Furthermore, in step S210, the CPU 14 issues a first fire alert from the alarm device 42 using the function of the alarm unit 64. In this first fire alert, as one example, along with an audible alarm, the alarm device 42 issues voices and other messages urging people to check whether anything is burning and where a fire extinguisher is located, urging people to ventilate the room by opening a window near the source of the fire, and urging people to take firefighting measures if possible. This allows people in the building 12 to ventilate the room and take firefighting measures.

[0076] Here, although not shown, the CPU 14 again acquires information on the CO concentration from the acquisition unit 50.

[0077] Then, in step S212, the CPU 14 determines, by the function of the determination unit 52, whether or not the CO concentration newly acquired by the acquisition unit 50 is 1 ppm or more.

[0078] If the CPU 14 determines in step S212 that the CO concentration is not 1 ppm or more, it ends the process.

[0079] On the other hand, if the CPU 14 determines in step S212 that the CO concentration is 1 ppm or more, the process proceeds to step S214.

[0080] In step S214, the CPU 14 determines whether the CO concentration newly acquired by the acquisition unit 50 is 50 ppm or more using the function of the determination unit 52. This concentration is the concentration permitted for occupational health in Japan.

[0081] If the CPU 14 determines in step S214 that the CO concentration is not 50 ppm or more, the process returns to step S212.

[0082] On the other hand, if the CPU 14 determines in step S214 that the CO concentration is 50 ppm or higher, the process proceeds to step S216.

[0083] In step S216, the CPU 14 uses the function of the notification unit 64 to issue a second fire alert from the alarm device 42. As one example of this second fire alert, an audible alarm and a voice instruction to evacuate are played from the alarm device 42. This allows people in the building 12 to evacuate quickly and avoid carbon monoxide poisoning.

[0084] In step S218, the CPU 14 automatically calls the fire department by dialing 119 using the function of the reporting unit 70, and then ends the process. As a result, a report is made when a CO concentration of 50 ppm or more is measured, allowing the fire brigade to quickly rush to the building 12 to carry out firefighting activities.

[0085] [Supplementary explanation of the above embodiment] In the above embodiment, the building 12 is described as a residence capable of first-class ventilation and central air conditioning, and is configured to include a kitchen equipped with a gas stove, a bathroom, a toilet, multiple living rooms, etc., but this is not limited to this. For example, the building may not be equipped with either or both of the first-class ventilation and central air conditioning systems. Also, the building may not be a residence. Furthermore, the building may not include a kitchen, bathroom, toilet, etc.

[0086] Furthermore, in the above embodiment, the information processing device 10 has been described as being configured to include a first-class ventilation outlet control unit 54, a whole-building air-conditioning outlet control unit 56, an interior fittings control unit 58, and a third-class ventilation outlet control unit 60, but is not limited to this, and it may be configured to have some function of performing control to suppress the inflow of air from one room to another when the determination unit determines that the gas concentration is above a reference value.

[0087] Furthermore, in the above embodiment, the information processing device 10 has been described as including the third-class ventilation opening control unit 60, the lighting control unit 62, the alarm unit 64, the gas valve control unit 66, the power cutoff unit 68, and the reporting unit 70, but this is not limiting, and the information processing device does not have to include these components. For example, if the information processing device does not include a reporting unit, in the second fire alert by the alarm unit 64 in step S216, a voice instructing the user to call 119 may be played from the alarm device 42.

[0088] Furthermore, the processing performed by the CPU 14 after reading the program in the above embodiment may be performed by various processors other than the CPU 14. Examples of such processors include dedicated electrical circuits, such as programmable logic devices (PLDs) (such as field-programmable gate arrays (FPGAs)) whose circuit configuration can be changed after fabrication, and application-specific integrated circuits (ASICs) that are processors with circuit configurations specifically designed to perform specific processing. The processing may be performed by one of these various processors, or by a combination of two or more processors of the same or different types, such as multiple FPGAs or a combination of a CPU and an FPGA. The hardware structure of these various processors is, more specifically, an electrical circuit that combines circuit elements such as semiconductor devices.

[0089] In the above embodiment, various data is stored in the storage 20, but this is not limiting. For example, a non-transitory recording medium such as a CD (Compact Disk), a DVD (Digital Versatile Disk), or a USB (Universal Serial Bus) memory may be used as the storage unit. In this case, various programs and data are stored in these recording media.

[0090] Furthermore, the processing flow described in the above embodiment is an example, and unnecessary steps may be deleted, new steps may be added, or the processing order may be changed within the scope of the main idea.
