DETAILED DESCRIPTION OF THE INVENTION

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A disaster prevention system according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention is not limited to the embodiment.

[0012] [Basic Concept of the Embodiment] First, the basic concept of the embodiment will be described. The embodiment generally relates to a disaster prevention system.

[0013] Here, the term "disaster prevention system" refers to a system that performs disaster prevention processing, and is a concept that includes, for example, a dedicated system that performs disaster prevention processing, a system that is realized by implementing a function that performs disaster prevention processing in a general-purpose system (for example, a system that includes a general-purpose computer, etc.), etc. This disaster prevention system includes, for example, a determination means and an output means.

[0014] The "determination means" is a means for determining whether an abnormality has occurred in a first residential area among the multiple residential areas. An "abnormality" refers to something that is different from normal, and is a concept that includes, for example, a fire or a gas leak. A "residential area" is an area where residents reside, and is a concept that includes, for example, each dwelling unit in a multifamily housing complex such as an apartment building, temporary housing, housing for disaster victims, each detached house in a housing complex, and a group home (e.g., a home where multiple care recipients and caregivers live together), or each dwelling unit or house. A "first residential area" is a part of the multiple residential areas, specifically a residential area other than the second residential area described below, and is a concept that includes, for example, a single dwelling unit or house, multiple dwelling units or houses, etc. A "second residential area" is a part of the multiple residential areas, specifically a residential area different from the first residential area, and is a concept that includes, for example, specific examples similar to the "first residential area."

[0015] Furthermore, the "output means" refers to a means for outputting display alarm information via a first alarm device that issues an alarm for at least the first living area when the determination means determines that an abnormality has occurred in the first living area, and more specifically, a means for performing disaster prevention processing, which is processing related to disaster prevention in the first living area, in cooperation with another device different from the first alarm device, and is a concept that includes, for example, causing the first alarm device to emit light and output display alarm information, and is also a concept that includes means for outputting abnormality occurrence information from a second alarm device in a manner different from the display alarm information output via the first alarm device, and is also a concept that includes means for outputting display alarm information from the alarm output means of the first alarm device. The "abnormality occurrence information" will be described later.

[0016] Furthermore, the term "display alarm information" refers to information related to an abnormality, specifically information output to the outside or inside of the residential area, for example, information output via a first alarm device, which is an alarm device in the residential area where an abnormality has been determined. It is also visually recognizable information, including, for example, information displayed by light, images, text, etc. The term "display alarm information" refers to, for example, information for notifying the occurrence of an abnormality. The term "abnormality occurrence information" refers to information related to an abnormality, specifically information output to the outside or inside of the residential area, for example, information output via a second alarm device, which is an alarm device other than the first alarm device, and it is also visually recognizable information, including, for example, information displayed by light, images, text, etc. The term "abnormality occurrence information" refers to, for example, information identifying that the determination means has determined that an abnormality has occurred in the first residential area. The display alarm information and the abnormality occurrence information may be output by the output means in the same manner or in different manners. Note that the "mode" here refers to the manner in which information is output, and is a concept that includes, for example, the light emission mode, which is the manner in which light is emitted. In particular, when these pieces of information are output in mutually different modes, for example, each piece of information may be output in a different type such as light emission, image, or text, or the same type of information (for example, light emission) may be output in different modes (for example, by changing the light emission timing, blinking speed, or light emission intensity).

[0017] Furthermore, the term "first alarm device" refers to a device that issues an alarm for at least a first living area among a plurality of living areas, specifically, a device that issues an alarm at least to the outside or inside of the first living area, and a device in which at least a portion of the alarm output means of the first alarm device is provided outside or inside the first living area, and is a concept that includes, for example, a device that issues at least a visible alarm, and as an example, a device that emits light, outputs images, outputs text, etc. Furthermore, the term "first alarm device" refers to, for example, a device that is associated with the first living area, and is a concept that includes, for example, a device that is provided at a position corresponding to the position of the first living area (for example, the outer surface of a wall or door of the first living area). Furthermore, the term "alarm output means" refers to a part of the first alarm device, and is a concept that includes, for example, some components for outputting information (note that the alarm output means of the second alarm device described below has a similar concept).

[0018] Furthermore, "other devices" refers to devices that are different from the first alarm device, and specifically, is a concept that includes devices of the same type and devices of different types, for example, a second alarm device, a lock device, a recording device, etc.

[0019] Furthermore, the term "second alarm device" refers to a device that issues an alarm for at least a second living area among a plurality of living areas, specifically, a device that issues an alarm at least to the outside or inside of the second living area, and a device in which at least a portion of the alarm output means of the second alarm device is provided outside or inside the second living area, and is a concept that includes, for example, a device of the same type as the first alarm device that issues at least a visible alarm, and one example is a device that emits light, outputs images, outputs text, etc. Furthermore, the term "second alarm device" refers to, for example, a device that is associated with the second living area, and is a concept that includes, for example, a device that is provided at a position corresponding to the position of the second living area (for example, the outer surface of a wall or door of the second living area).

[0020] Furthermore, the term "locking device" refers to a device that locks or unlocks the first living area, and is, for example, a different type of device from the first alarm device, and is a concept that includes devices realized using known technologies such as electric locking devices. The term "recording device" refers to a device that records information about the resident of the first living area, and is, for example, a different type of device from the first alarm device. The term "recording device" refers to a device that receives speech from the resident and performs arbitrary processing (e.g., control of home appliances) based on the received speech, and is a concept that includes devices that record information about the speech as information about the resident, and is, for example, a concept that includes devices realized using technology such as so-called smart speakers. The term "information about the resident of the first living area" refers to a concept that includes, for example, information about the time of speech, the content of the speech, and environmental information at the time of speech (room temperature, humidity, outdoor weather, etc.) when a resident living in the first living area speaks to the recording device.

[0021] Furthermore, "performing disaster prevention processing, which is processing related to disaster prevention in the first residential area in cooperation with other devices" is a concept that includes, for example, at least communicating with other devices for disaster prevention purposes and performing disaster prevention processing.

[0022] Furthermore, the term "disaster prevention processing" refers to processing related to disaster prevention in the first residential area, and specifically refers to processing carried out in cooperation with other measures, and is a concept that includes, for example, the first to fourth disaster prevention processing. The term "first disaster prevention processing" refers to processing carried out in cooperation with the second alarm device, and is a concept that includes, for example, processing for outputting, via the second alarm device, abnormality occurrence information, which is information that identifies that the determination means has determined that an abnormality has occurred in the first residential area. The term "second disaster prevention processing" refers to processing carried out in cooperation with the second alarm device, and is a concept that includes, for example, processing for outputting, via the second alarm device, residential area identification information, which is information that identifies the first residential area in which the determination means has determined that an abnormality has occurred. The term "third disaster prevention processing" refers to processing carried out in cooperation with a locking device, and is a concept that includes, for example, processing for locking or unlocking the first residential area using the locking device.

[0023] In the following embodiment, the first disaster prevention process will be described when the "residential area" is each dwelling unit in an apartment building and the "abnormality" is a fire, and the second to fourth disaster prevention processes will be described in modified examples.

[0024] [Specific details of the embodiment] Next, specific details of the embodiment will be described.

[0025] (composition) First, the configuration of the disaster prevention system according to this embodiment will be described. Fig. 1 is a diagram showing a living area to which the disaster prevention system according to this embodiment is applied, Fig. 2 is a block diagram showing the disaster prevention system, and Fig. 3 is a diagram showing an example of installation of an indicator light device. In reality, there are four or more living areas 8, but Fig. 1 illustrates and explains three living areas 81 to 83 as representatives. Furthermore, these living areas 81 to 83 will be collectively referred to as "living area 8" unless they are to be described separately from one another (the same applies to the detector 1, indicator light device 2, and door 7).

[0026] The disaster prevention system 900 in FIG. 2 includes, for example, a detector 1 and an indicator light device 2.

[0027] (Configuration-sensor) Detector 1 is an abnormality detection means for detecting a fire occurring in living area 8 in which it is installed in Fig. 1, and is, for example, a device that performs wireless communication with an external device (for example, indicator light device 2). Sensor 1 also includes, for example, detector 111 that detects a fire in living area 81, detector 121 that detects a fire in living area 82, and detector 131 that detects a fire in living area 83. The specific type and configuration of this detector 1 are arbitrary, but for example, it may be installed in living area 8 in Fig. 1 and configured to include means for detecting the occurrence of a fire by detecting smoke generated by a fire, wireless communication means, etc.

[0028] (Configuration-indicator light device) The indicator light device 2 is an alarm device and is installed, for example, on the door 7 that separates the inside and outside of the living area 8 as shown in Figures 1 and 3, and more specifically, is installed on the outdoor side of the door 71 of the living area 81. The indicator light device 2 also includes an indicator light device 201 installed on the door 71 of the living area 81, an indicator light device 202 installed on the door 72 of the living area 82, and an indicator light device 203 installed on the door 73 of the living area 83. This indicator light device 2 includes, for example, a communication unit 21, a display unit 22, a recording unit 23, and a control unit 24 as shown in Figure 2.

[0029] (Configuration - Indicator light device - Communication department) The communication unit 21 is a communication means for performing wireless communication at least with the sensor 1 or another indicator light device 2. The specific type and configuration of this communication unit 21 are arbitrary, but it can be configured using, for example, a known wireless communication circuit or the like.

[0030] (Configuration - indicator light device - display section) The display unit 22 is an alarm output means that outputs display alarm information. The specific type and configuration of the display unit 22 are arbitrary, but for example, it can be configured to include a light-emitting diode (LED) that outputs light, and is provided, for example, outside the living area 8. Note that in this embodiment, a case will be described in which the entire display unit 22 is provided outside the living area 8, but it may also be configured so that only a part of it is provided outside the living area 8.

[0031] (Configuration - Indicator light device - Recording unit) The recording unit 23 is a recording means for recording programs and various data necessary for the operation of the signal light device 2, and is configured using, for example, a flash memory (not shown) as an external recording device. However, instead of or in addition to the flash memory, any other recording medium can be used, including a magnetic recording medium such as a hard disk or a magnetic disk, or an optical recording medium such as a DVD or Blu-ray disc. As shown in Fig. 2, the recording unit 23 stores the signal light device ID, map information, occupancy area related information, and operating condition information.

[0032] (Configuration - Indicator Light Device - Recording Unit - Indicator Light Device ID) The "indicator light device ID" is device identification information (identification information is also referred to as "ID") that uniquely identifies the indicator light device 2. The specific method for recording such an indicator light device ID is arbitrary, but for example, it is recorded by inputting it via the communication unit 21 at the time of manufacture, installation, or any other arbitrary timing (the same applies to map information, occupancy area related information, and operating condition information). For example, it is assumed that "ID201" is recorded as the "indicator light device ID" in the recording unit 23 of the indicator light device 201, "ID202" is recorded as the "indicator light device ID" in the recording unit 23 of the indicator light device 202, and "ID203" is recorded as the "indicator light device ID" in the recording unit 23 of the indicator light device 203.

[0033] (Configuration - Indicator light device - Recording unit - Map information) "Map information" is information that identifies a map that can identify the location of each residential area 8, including residential areas 81 to 83 in Figure 1, and is information that can identify, for example, the location of each residential area 8 based on any reference object (e.g., a street center, wall, beam, or pillar, etc.) for the building of residential area 8 (e.g., an apartment building that is a multi-family dwelling), or the floor number or plan coordinates that indicate the location of components (e.g., door 7, etc.) set in each residential area.

[0034] (Configuration - Indicator light device - Recording unit - Living area related information) "Residential area related information" is information related to the residential area 8, such as information that identifies a device installed in the residential area 8 or the location of the residential area 8. Figure 4 is a diagram illustrating residential area related information. As shown in Figure 4, the residential area related information stores, for example, the items "residential area ID," "detector ID," "indicator light device ID," and "location information," and information corresponding to each item, in mutual correspondence. Information corresponding to the item "residential area ID" is a residential area ID that uniquely identifies a residential area (in Figure 4, "ID81" is the residential area ID of residential area 81 in Figure 1, "ID82" is the residential area ID of residential area 82, and "ID83" is the residential area ID of residential area 83, etc.). The information corresponding to the item "detector ID" is a detector ID that uniquely identifies the detector 1 installed in each residential area 8 (in FIG. 4, "ID111" as the detector ID of detector 111, "ID121" as the detector ID of detector 121, and "ID131" as the detector ID of detector 131, etc.). The information corresponding to the item "indicator light device ID" is, as mentioned above, an indicator light device ID that uniquely identifies the indicator light device 2 installed in each residential area 8 (in FIG. 4, "ID201" as the indicator light device ID of indicator light device 201, "ID202" as the indicator light device ID of indicator light device 202, and "ID203" as the indicator light device ID of indicator light device 203, etc.). The information corresponding to the item "location information" is location information that specifies the location of the residential area 8. This location information is stored to enable the relative positional relationships between the residential areas 8 (for example, the distance between each residential area 8) to be specified by referring to the map information in FIG. 2. For example, in Figure 4, the names of the residential areas 8 within the building, such as "Room 101" to "Room 103," are recorded, and by referring to the map information in Figure 2, it is possible to identify the relative positional relationships between each residential area 8 from information such as "Room 101" to "Room 103."

[0035] (Configuration - Indicator light device - Recording unit - Operating condition information) "Operating condition information" is information that specifies the operating conditions of the indicator light device 2. Fig. 5 is a diagram illustrating an example of the operating condition information. As shown in Fig. 5, the operating condition information stores, for example, the items "status information" and "light emission mode information" and information corresponding to each item in mutual correspondence.

[0036] The information corresponding to the item "status information" is status information that specifies the status related to the coordination of the indicator light device 2. This status information specifies whether the indicator light device 2 is operating as a coordination source device or a coordination destination device, and, if the indicator light device 2 is operating as a coordination destination device, information that specifies the position of the coordination destination device relative to the coordination source device is used.

[0037] The "cooperation source device" refers to the indicator light device 2 that is the source of information in communication between each indicator light device 2 for disaster prevention purposes, and for example, corresponds to the first alarm device and indicates the indicator light device 2 installed in the living area 8 where a fire has been detected. The "cooperation destination device" refers to the indicator light device 2 that is the destination of information from the aforementioned coordination source device in communication between each indicator light device 2 for disaster prevention purposes, and for example, corresponds to the second alarm device and indicates the indicator light device 2 installed in the living area 8 where no fire has been detected.

[0038] 5, "Coordination Source," "Coordination Destination 1," "Coordination Destination 2," "Coordination Destination 3," and "Coordination Destination 4" are recorded. Note that "Coordination Source" indicates a state in which the device is operating as a coordination source device, and "Coordination Destination 1," "Coordination Destination 2," "Coordination Destination 3," and "Coordination Destination 4" indicate a state in which the device is operating as a coordination destination device. In particular, the numerical values ​​"1," "2," "3," and "4" in "Coordination Destination 1," "Coordination Destination 2," "Coordination Destination 3," and "Coordination Destination 4" indicate a position relative to the coordination source device, with "1" to "3" indicating that the device is on the same floor as the coordination source device, and the larger the numerical value, the further away the device is, and "4" indicating that the device is not on the same floor as the coordination source device. In more detail, regarding "1" to "3," "1" indicates that the installation location of the target device corresponds to the residential area 8 that is one area next (i.e., adjacent) to the residential area 8 in which the source device is installed; "2" indicates that the installation location of the target device corresponds to the residential area 8 that is two areas away from the residential area 8 in which the source device is installed; and "3" indicates that the installation location of the target device corresponds to the residential area 8 that is three or more areas away from the residential area 8 in which the source device is installed.

[0039] The information corresponding to the item "Light Emitting Mode Information" is light emitting mode information that specifies the light emitting mode of the display unit 22. This light emitting mode information may be any information, but for example, in FIG. 4, the light emitting mode is specified as the light intensity and the blinking rate (the time interval between blinking). For example, the stronger the light intensity and the faster the blinking rate, the closer the fire source is indicated. In more detail, the light intensity and the blinking rate are each set to five levels, and an example will be described in which "Intensity: 5, Speed: 5" is recorded as in FIG. 5. Note that "Intensity: 5, Speed: 5" specifies that the light intensity corresponds to "5" and that the blinking rate corresponds to "5." Furthermore, for the numerical values ​​of the light intensity and blinking rate exemplified in FIG. 5, it is assumed that the higher the value, the stronger the intensity and the faster the blinking rate. The specific values ​​for these intensities and flashing speeds are arbitrary, but for example, "intensity: 5, speed: 5" indicates that the light is about "7000 to 8000 lumens" and flashes at intervals of about "0.5 to 1 second," while "intensity: 4, speed: 4" indicates that the light is about "6000 to 6500 lumens" and flashes at intervals of about "2 to 3 seconds."

[0040] (Configuration - Indicator light device - Control unit) 2 is a control means for controlling the signal light device 2, and is specifically a computer including a CPU, various programs interpreted and executed on the CPU (including basic control programs such as an OS and application programs that are started on the OS and implement specific functions), and an internal memory such as RAM for storing programs and various data. In particular, the program according to the embodiment is installed in the signal light device 2 via any recording medium or a network, thereby substantially configuring each part of the control unit 24.

[0041] This control unit 24 conceptually includes a determination unit 241 and an output unit 242. The determination unit 241 is a determination means for determining whether or not an abnormality has occurred in a first living area among the multiple living areas 8. The output unit 242 is an output means for outputting display warning information via the indicator light device 2, which is a first warning device that issues a warning for at least the first living area, when the determination unit 241 determines that an abnormality has occurred in the first living area, and more specifically, is a means for performing disaster prevention processing, which is processing related to disaster prevention in the first living area, in cooperation with another device different from the first warning device. The processing performed by each unit of this control unit 24 will be described later.

[0042] (process) Next, we will explain the disaster prevention process on the coordination source side and the disaster prevention process on the coordination destination side that are executed by the disaster prevention system 900 configured in this manner. Here, for example, each of the signal light devices 2 in Fig. 1 functions as either a coordination source device or a coordination destination device depending on the location of a fire, and therefore executes both the disaster prevention process on the coordination source side and the disaster prevention process on the coordination destination side, but we will particularly explain an example where a fire breaks out in the living area 81, the signal light device 201 functions as the coordination source device, and the signal light devices 202 and 203 function as coordination destination devices.

[0043] (Processing - Disaster prevention processing on the cooperation source side) First, the disaster prevention processing on the coordination source side will be explained. Fig. 6 is a flowchart of the disaster prevention processing on the coordination source side (steps will be abbreviated as "S" in the following explanation of each process). The "disaster prevention processing on the coordination source side" is, in general, processing executed by the indicator light device 2, and more specifically, processing for detecting the occurrence of a fire and operating as a coordination source device. The timing for executing this disaster prevention processing on the coordination source side is arbitrary, but for example, when each device in the disaster prevention system 900 is powered on, it is started up and begins execution, and the explanation will begin from the point where execution has begun (the same applies to the disaster prevention processing on the coordination destination side).

[0044] In SA1 of FIG. 6, the determination unit 241 determines whether or not a fire has occurred. While specific details are arbitrary, for example, the detector 1 may output an alarm signal when it detects a fire, and the determination unit 241 monitors the communication unit 21 to determine whether or not this alarm signal has been received. If the alarm signal has not been received, it determines that no fire has occurred (NO in SA1), and repeatedly executes SA1 until it determines that a fire has occurred. If the alarm signal has been received, it determines that a fire has occurred (YES in SA1), and proceeds to SA2. Here, for example, if a fire has occurred in the occupancy area 81, the detector 111 detects the fire and outputs an alarm signal, and the determination unit 241 of the indicator light device 201 receives the alarm signal and determines that a fire has occurred.

[0045] At SA2 in Fig. 6, the output unit 242 determines the light emission mode. While the specific details are arbitrary, for example, the indicator light device 201 operates as a coordination source device because it has determined that a fire has occurred. Specifically, the output unit 242 refers to the operating condition information in Fig. 5 to acquire light emission mode information whose status information is "coordination source," and determines the light emission mode specified by the acquired light emission mode information as the light emission mode of the indicator light device 2. Here, for example, the output unit 242 of the indicator light device 201 refers to the operating condition information in Fig. 5 to acquire light emission mode information whose status information is "coordination source," "intensity: 5, speed: 5," and determines that the light emission mode of the indicator light device 201 is to flash light with an intensity corresponding to "5" at a flashing speed corresponding to "5."

[0046] At SA3 in Fig. 6, the output unit 242 starts emitting light, thereby starting the output of display warning information. While specific details are arbitrary, for example, the light emission mode determined at SA2 is specified, and the display unit 22 in Fig. 3 starts emitting light in the determined light emission mode. Here, for example, the output unit 242 of the signal light device 201 specifies the light emission mode corresponding to "intensity: 5, speed: 5", which is the light emission mode determined at SA2, and the display unit 22 in Fig. 3 starts emitting light in the light emission mode corresponding to the determined "intensity: 5, speed: 5". In this case, the display unit 22 of the signal light device 201 starts flashing so as to repeatedly output light of about "7000 lumens to 8000 lumens" at intervals of about "0.5 seconds to 1 second".

[0047] In SA4 of FIG. 6, the output unit 242 cooperates with other indicator light devices 2 by transmitting an alarm relay signal. The "alarm relay signal" is a signal for communicating that a fire has been detected, and is, for example, a signal that includes at least the indicator light device ID of the cooperation source device. While the specifics of SA4 are arbitrary, for example, the output unit 242 may acquire the indicator light device ID recorded in its own recording unit 23, add the acquired indicator light device ID as the indicator light device ID of the cooperation source device to generate an alarm relay signal, and transmit the generated alarm relay signal. This alarm relay signal then reaches, for example, surrounding indicator light devices 2.

[0048] Here, for example, the output unit 242 of the indicator light device 201 acquires "ID201," which is the indicator light device ID recorded in its own recording unit 23, adds the acquired "ID201" as the indicator light device ID of the cooperation source device, generates an alarm relay signal, and transmits the generated alarm relay signal. This alarm relay signal then reaches, for example, the indicator light device 202, which is a nearby indicator light device 2.

[0049] In SA5 of FIG. 6, the determination unit 241 determines whether or not recovery has occurred. While specific details are arbitrary, for example, when a predetermined operation (an operation for recovery) is performed on a disaster prevention receiver (not shown), the disaster prevention receiver outputs a recovery signal, and the determination unit 241 monitors the communication unit 21 to determine whether or not this recovery signal has been received. If the recovery signal is not received, it is determined that recovery has not occurred (NO in SA5), and SA5 is repeatedly executed until it is determined that recovery has occurred. Furthermore, if a recovery signal is received, it is determined that recovery has occurred (YES in SA5), and the process proceeds to SA6. Here, for example, when a firefighter performs a predetermined operation on the disaster prevention receiver, the disaster prevention receiver outputs a recovery signal, and the determination unit 241 of the indicator light device 201 receives the recovery signal and determines that recovery has occurred.

[0050] At SA6 in Fig. 6, the output unit 242 ends the output of the display warning information by ending light emission. Specifically, although any method is possible, light emission is ended, for example, by turning off the display unit 22 in Fig. 3. Here, for example, the output unit 242 of the indicator light device 201 ends the flashing of a light of about "7000 lumens to 8000 lumens" at intervals of about "0.5 seconds to 1 second" on the display unit 22 of the indicator light device 201.

[0051] In SA7 in FIG. 6, the output unit 242 cooperates with other indicator light devices 2 by transmitting a restoration relay signal. The "restoration relay signal" is a signal for communicating that restoration has occurred, and is, for example, a signal that includes at least the indicator light device ID of the cooperation source device. While specific details about SA7 are arbitrary, it is, for example, similar to SA4, in that it acquires the indicator light device ID recorded in its own recording unit 23, adds the acquired indicator light device ID as the indicator light device ID of the cooperation source device to generate a restoration relay signal, and transmits the generated restoration relay signal. This restoration relay signal then reaches, for example, surrounding indicator light devices 2.

[0052] Here, for example, the output unit 242 of the indicator light device 201 acquires "ID201", which is the indicator light device ID recorded in its own recording unit 23, adds the acquired "ID201" as the indicator light device ID of the coordination source device to generate a recovery relay signal, and transmits the generated recovery relay signal. This recovery relay signal then reaches, for example, the indicator light device 202, which is the surrounding indicator light device 2. This ends the coordination source side disaster prevention processing.

[0053] (Processing - Disaster prevention processing on partner side) Next, the disaster prevention process on the coordination destination side will be described. Fig. 7 is a flowchart of the disaster prevention process on the coordination destination side. The "disaster prevention process on the coordination destination side" is generally a process executed by the indicator light device 2, and more specifically, a process for operating as a coordination destination device based on communication with the coordination source device.

[0054] In SB1 of FIG. 7, the control unit 24 determines whether it has received an alarm relay signal transmitted by another indicator light device 2 acting as a coordination source device. While specific details are optional, for example, the control unit 24 may monitor the communication unit 21 to acquire the indicator light device ID of the coordination source device contained in the alarm relay signal received by the communication unit 21, and also acquire the indicator light device ID of its own recording unit 23, and then determine whether these acquired indicator light device IDs match. If the indicator light device IDs match, the control unit 24 determines that the alarm relay signal received by the communication unit 21 is an alarm relay signal transmitted by the control unit 21 as a coordination source device and relayed by another indicator light device 2, and determines that the alarm relay signal has not been received (NO in SB1), and repeatedly executes SB1 until it determines that the alarm relay signal has been received. If the indicator light device IDs do not match, the control unit 24 determines that the alarm relay signal received by the communication unit 21 is transmitted by another indicator light device 2 acting as a coordination source device, and determines that the alarm relay signal has been received (YES in SB1), and proceeds to SB2. Here, for example, when the control unit 24 of the indicator light device 202 receives an alarm relay device including "ID201", since its own indicator light device ID is "ID202", the acquired "ID201" and "ID202", which is the indicator light device ID of its own recording unit, do not match each other, and it determines that an alarm relay signal has been received.

[0055] At SB2 in Fig. 7, the control unit 24 determines the light emission mode. Specifically, although the specific determination is arbitrary, for example, since the indicator light device 2 itself has not determined that a fire has occurred (i.e., another indicator light device 2 has determined that a fire has occurred), the control unit 24 operates as a coordination destination device. Specifically, the control unit 24 refers to the operating condition information in Fig. 5 and acquires the status information "Coordination destination 1" to "Coordination destination 4." Next, the control unit 24 refers to the residential area related information in Fig. 4 and acquires the location information corresponding to the indicator light device ID of the coordination source device included in the alarm relay signal acquired at SB1 and the location information corresponding to its own indicator light device ID. Next, the control unit 24 refers to the map information in the recording unit 23 in Fig. 2 and identifies the relative positional relationship between the residential area 8 corresponding to the acquired location information of the coordination source device and the residential area 8 corresponding to its own location information (i.e., the location information of the coordination destination device). Next, one piece of status information corresponding to the identified relative positional relationship is selected from the acquired "associated destination 1" to "associated destination 4" described above, and light emission mode information corresponding to the selected state information is acquired in the operating condition information of Figure 5, and the light emission mode identified by the acquired light emission mode information is determined as the light emission mode of the indicator light device 2.

[0056] Here, for example, the control unit 24 of the signal light device 202 refers to the operating condition information in Fig. 5 to acquire the status information "Cooperation destination 1" to "Cooperation destination 4". Next, referring to the residential area related information in Fig. 4, it acquires "Room 101" as the location information corresponding to "ID201", which is the signal light device ID of the coordination source device included in the alarm relay signal acquired by SB1, and "Room 102" as the location information corresponding to "ID202", which is its own signal light device ID, and then refers to the map information in the recording unit 23 in Fig. 2 to identify the relative positional relationship between the residential area 81 corresponding to "Room 101", which is the location information of the coordination source device acquired above, and the residential area 82 corresponding to "Room 102", which is its own location information (i.e., the location information of the coordination destination device). Next, since the installation location of the target device corresponds to the residential area 82 adjacent to the residential area 81 in which the source device is installed, "target device 1" is selected from the previously acquired "target device 1" to "target device 4", and in the operating condition information of Figure 5, "intensity: 4, speed: 4" is acquired as the light emission mode information corresponding to the selected "target device 1", and it is determined that the light emission mode of the indicator light device 202 will be to flash light of an intensity corresponding to "4" at a flashing speed corresponding to "4".

[0057] At SB3 in Fig. 7, the control unit 24 starts emitting light, thereby starting to output abnormality occurrence information. Specifically, although any method is possible, for example, the light emission mode determined at SB2 is specified, and the display unit 22 in Fig. 3 starts emitting light in the determined light emission mode. Here, for example, the control unit 24 of the signal light device 202 specifies the light emission mode corresponding to "intensity: 4, speed: 4", which is the light emission mode determined at SB2, and starts emitting light in the light emission mode corresponding to the determined "intensity: 4, speed: 4" on the display unit 22 in Fig. 3. In this case, the display unit 22 of the signal light device 202 starts flashing so as to repeatedly output light of approximately "6000 lumens to 6500 lumens" at intervals of approximately "2 to 3 seconds".

[0058] In SB4 of FIG. 7, the control unit 24 cooperates with other indicator light devices 2 by transmitting and relaying an alarm relay signal. Specifically, although this is arbitrary, for example, the control unit 24 transmits and relays the alarm relay signal received in SB1. This alarm relay signal then reaches, for example, a nearby indicator light device 2. Here, for example, the control unit 24 of the indicator light device 202 transmits and relays an alarm relay signal that includes "ID201" as the indicator light device ID of the cooperation source device. This alarm relay signal then reaches, for example, the indicator light device 203, which is the nearby indicator light device 2.

[0059] In SB5 of FIG. 7, the control unit 24 determines whether it has received a return relay signal transmitted by another indicator light device 2 as the cooperation source device. While specific details are optional, for example, the control unit 24 may monitor the communication unit 21 to acquire the indicator light device ID of the cooperation source device contained in the return relay signal received by the communication unit 21, and also acquire the indicator light device ID of the cooperation source device contained in the alarm relay signal acquired in SB1, and then determine whether these acquired indicator light device IDs match. If the indicator light device IDs do not match, the control unit 24 determines that the return relay signal received by the communication unit 21 does not correspond to the alarm relay signal received in SB1, and then determines that the return relay signal has not been received (NO in SB5), and repeatedly executes SB5 until it determines that the return relay signal has been received. If the indicator light device IDs match, the control unit 24 determines that the return relay signal received by the communication unit 21 corresponds to the alarm relay signal received in SB1, and then determines that the return relay signal has been received (YES in SB5), and proceeds to SB6. Here, for example, when the control unit 24 of the indicator light device 202 receives a return relay device containing "ID201," since the alarm relay signal received by SB1 also contains "ID201," the control unit 24 determines that these match and that a return relay signal has been received.

[0060] At SB6 in FIG. 7, the control unit 24 cooperates with other indicator light devices 2 by transmitting and relaying a return relay signal. Specifically, this is arbitrary, but for example, the control unit 24 transmits and relays the return relay signal received at SB5. This return relay signal then reaches, for example, a nearby indicator light device 2. Here, for example, the control unit 24 of the indicator light device 202 transmits and relays a return relay signal that includes "ID201" as the indicator light device ID of the cooperation source device. This return relay signal then reaches, for example, the indicator light device 203, which is the nearby indicator light device 2.

[0061] At SB7 in Fig. 7, the control unit 24 ends the output of the abnormality occurrence information by ending the light emission. Specifically, although this is arbitrary, the light emission is ended, for example, by turning off the display unit 22 in Fig. 3. Here, for example, the control unit 24 of the signal light device 202 ends the flashing of a light of about "6000 lumens to 6500 lumens" at intervals of about "2 to 3 seconds" on the display unit 22 of the signal light device 202. This ends the disaster prevention process on the cooperation destination side.

[0062] (Processing-operation example) Next, an example of the operation of the disaster prevention system 900 will be described. Here, for example, as described above, an example of the operation when a fire breaks out in the living area 81 in Fig. 1 will be described. First, when a fire breaks out in the living area 81, the sensor 111 detects the occurrence of the fire and outputs an alarm signal, so the indicator light device 201 determines the light emission mode corresponding to "intensity: 5, speed: 5" in Fig. 5 in SA2 after YES in SA1 in Fig. 6, and then starts emitting light in the determined mode in SA3 and transmits an alarm relay signal to SA4.

[0063] On the other hand, the indicator light device 202 receives the alarm signal, and in SB2 after YES in SB1 in Fig. 7, determines a light emission mode corresponding to "intensity: 4, speed: 4", then starts emitting light in the determined mode in SB3, and relays an alarm relay signal to SB4. On the other hand, the indicator light device 203 receives the alarm signal, and in SB2 after YES in SB1 in Fig. 7, determines a light emission mode corresponding to "intensity: 3, speed: 3", then starts emitting light in the determined mode in SB3, and relays an alarm relay signal to SB4.

[0064] Then, by visually checking the light emitted from the display unit 22 of each indicator light device 2, a user outside the residential area 8 (for example, a resident or a firefighter) can recognize that a fire has occurred and that the source of the fire is the residential area 81 based on the intensity or flashing rate of the emitted light, and can take the necessary measures.

[0065] Thereafter, when a predetermined operation is performed on a disaster prevention receiver (not shown), indicator light device 201 stops emitting light at SA5 after SA5 in Figure 6, and then transmits a recovery relay signal at SA7. Meanwhile, indicator light device 202 receives the recovery relay signal, transmits a recovery relay signal at SB6 after YES at SB5 in Figure 7, and then stops emitting light at SB7. Meanwhile, indicator light device 203 also performs the same process as indicator light device 202 and stops emitting light at SB7. This concludes the explanation of this operational example.

[0066] (Effects of the embodiment) Thus, according to this embodiment, disaster prevention processing, which is processing related to disaster prevention in the first living area (e.g., living area 81), is performed in cooperation with other devices (e.g., indicator light devices 202, 203) different from the first alarm device (e.g., indicator light device 201).This makes it possible to perform disaster prevention processing from all angles, rather than just processing related to a single alarm by the first alarm device, thereby enabling disaster prevention to be carried out from multiple angles and improving disaster prevention capabilities.

[0067] Furthermore, by outputting abnormality occurrence information via a second alarm device (e.g., indicator light devices 202, 203) that issues an alarm for at least a second living area (e.g., living areas 82, 83), it is possible to notify the second living area of, for example, the occurrence of a fire, which is an abnormality. This makes it possible to notify residents near the first living area where a fire has been detected of the abnormality, and to enable them to quickly take the necessary disaster prevention measures (e.g., fire extinguishing, rescue, etc.).

[0068] Furthermore, by outputting abnormality occurrence information from the second alarm device in a manner different from the display alarm information output via the first alarm device, it is possible to output information about the abnormality not only from the first alarm device but also from the second alarm device, making it possible to notify a wide range of people of an abnormality in the first living area. Furthermore, for example, since the manner of information is different between the first alarm device and the second alarm device, it is possible to notify whether or not an abnormality has actually occurred in a living area, and it becomes possible to promptly take measures necessary for disaster prevention (for example, fire extinguishing, rescue, etc.).

[0069] Furthermore, by outputting display alarm information from the second alarm device in a different light emission mode from the first alarm device, for example, information regarding an abnormality can be output by light emission not only from the first alarm device but also from the second alarm device, making it possible to widely notify an abnormality in the first residential area. Furthermore, for example, since the light emission modes of the information are different between the first alarm device and the second alarm device, it is possible to notify whether an abnormality is actually occurring in the residential area, and it becomes possible to promptly take necessary disaster prevention measures (e.g., fire extinguishing, rescue, etc.). Furthermore, since an alarm can be reliably issued even at night, for example, disaster prevention capabilities can be improved. Furthermore, for example, even when an abnormality occurs and causes confusion and chaos in the surrounding area, the alarm can be reliably recognized visually.

[0070] Furthermore, by illuminating the first alarm device and outputting the display alarm information, an alarm can be issued reliably even at night, for example, thereby improving disaster prevention capabilities. Furthermore, even if a fire breaks out and causes chaos and confusion in the surrounding area, the alarm can be reliably recognized visually.

[0071] Furthermore, since the display unit 22 is provided outside the residential area 8, it can reliably notify people outside the residential area 8 of the occurrence of an abnormality, thereby enabling people in the vicinity of the residential area 8 to quickly take the necessary disaster prevention measures (for example, fire extinguishing, rescue, etc.).

[0072] [Modifications to the embodiment] Although the embodiments of the present invention have been described above, the specific configurations and means of the present invention can be modified and improved as desired within the scope of the technical ideas of the inventions set forth in the claims. Such modifications will be described below.

[0073] (About the problem to be solved and the effects of the invention) First, the problems that the invention aims to solve and the effects of the invention are not limited to those described above, and may vary depending on the implementation environment of the invention and the details of the configuration, and may solve only some of the problems described above or achieve only some of the effects described above.

[0074] (Regarding decentralization and integration) Furthermore, the above-described configuration is merely a functional concept and does not necessarily have to be physically configured as illustrated. In other words, the specific form of distribution or integration of each unit is not limited to that illustrated, and all or part of the units can be functionally or physically distributed or integrated in any unit. Furthermore, the term "device" in this application is not limited to a single device, but also includes a device composed of multiple devices. In particular, at least some of the functions of the signal light device 2 (e.g., the functions of the determination unit 241 or the output unit 242) may be provided in any device, including a disaster prevention receiver (not shown), and the signal light device 2 may be controlled by that device. In this case, the processing may be modified as appropriate so that the same processing as described in the embodiment can be performed.

[0075] (About information output (part 1)) Furthermore, in the above embodiment, a case has been described in which different information is output by varying the light intensity and blinking rate based on the operating condition information of Fig. 5, but this is not limiting. For example, by utilizing the fact that each signal light device 2 is configured to be able to communicate with each other, each signal light device 2 may sequentially blink its display unit 22 so as to give the user the impression that light is flowing from the side of the coordination target device farthest from the coordination source device toward the coordination source device. In this case, one of the signal light devices 2 (e.g., the coordination source device) may control the blinking timing of each signal light device 2. Alternatively, the direction of the impression of light flow may be reversed to provide evacuation guidance.

[0076] (About information output (part 2)) Also, different information may be output by, for example, varying the color or blinking pattern of the output light. Furthermore, for example, the display unit 22 in FIG. 2 may be provided with a character display means for displaying text, such as an electronic bulletin board, or an image display means for displaying images, such as a liquid crystal display, in addition to or instead of the LEDs described above, and text information or image information may be displayed via these display means. In such a configuration, for example, information identifying the location of the living area 8 where the fire has occurred (e.g., the floor number and name (Room 101, etc.)) may be displayed as text information or image information.

[0077] In particular, for example, when displaying text, any information can be registered in the recording unit 23, and in the event of a fire (i.e., when a fire alert is issued for a dwelling unit, or when a fire alert is issued in the neighborhood), resident information related to the resident (occupant) of the dwelling unit in which the indicator light device 2 is installed (for example, the age of the resident, the number of resident, the level of care required by the resident, whether or not the resident is a person requiring assistance in the event of a disaster), or the presence or absence of hazardous materials, etc. (hazardous material presence / absence information) can be displayed.

[0078] Furthermore, for example, when outputting different information by varying the color of light that is output, as an example, an LED capable of emitting two colors, red and green, can be used, and only the indicator light device 2 installed in the dwelling where a fire has been reported (the living area where a fire has been determined) can emit red light, and the indicator light devices 2 installed in the dwellings nearby the dwelling where a fire has been reported can emit green light.

[0079] Furthermore, for example, when different information is output by using different flashing patterns, etc., one example is to use the same light emission cycle and output different information by varying the duty ratio (the ratio of the time light is emitted to the light emission cycle) of the indicator light devices 2 installed in each dwelling unit (for example, by reducing the duty ratio as the distance from the dwelling unit where the fire alarm was issued increases).

[0080] Furthermore, for example, the light emission of the target device may be controlled based on the radio wave intensity from the source device. Specifically, the source device may transmit a predetermined signal (a signal of a predetermined intensity) other than the alarm relay signal, and the target device may receive the predetermined signal. The target device may then measure the received radio wave intensity of the predetermined signal it has received and control its own light emission mode according to the measured received radio wave intensity. In particular, information specifying the relationship between the received radio wave intensity and the light emission intensity (e.g., information specifying that the stronger the received radio wave intensity, the stronger the light emission intensity) may be recorded in the target device, and the target device may control its own light emission intensity by referring to the recorded information.

[0081] (Regarding the second disaster prevention measures) Furthermore, the indicator light device 2 of the above embodiment may be configured to perform a second disaster prevention process. While any specific implementation method may be used, for example, the output unit 242 of the indicator light device 2 may perform the second disaster prevention process at SB3 in FIG. 7. Specifically, the second disaster prevention process may be performed by acquiring the indicator light device ID of the cooperation source device contained in the alarm relay signal received at SB1, identifying location information corresponding to the acquired indicator light device ID in the residential area-related information in FIG. 4, and outputting the identified location information as residential area identification information. While any method may be used to output the location information, the location information (e.g., text information such as "Room 101" or map image information indicating Room 101) may be output as text information or image information in combination with the technology described in "(Information Output (Part 2))." In this configuration, by outputting residential area identification information via a second alarm device (e.g., indicator light devices 202, 203) that issues an alarm for at least a second residential area (e.g., residential areas 82, 83), it is possible to notify the second residential area of ​​the source of the fire, for example, and therefore it is possible to notify residents near the first residential area (e.g., residential area 81) where a fire has been detected of the source of the fire, and to enable them to quickly take necessary disaster prevention measures (e.g., fire extinguishing, rescue, etc.). In particular, since it is possible to identify the source of the fire, if evacuation is necessary, evacuation can be quickly carried out in a safe direction (e.g., a direction that avoids the source of the fire, etc.).

[0082] (Interpretation of the second disaster prevention measure) In the embodiment, as shown in FIG. 5, when it is noted that the light intensity of the linked target devices on the same floor increases and the blinking rate increases as they get closer to the linked source device, this difference in the light emission patterns of the multiple linked target devices can be interpreted as identifying the location of the linked source device (i.e., the living area 8 where the fire occurred), and in this case, it can also be interpreted as a second disaster prevention process being performed in the embodiment.

[0083] (Regarding the third disaster prevention measures) Furthermore, the indicator light device 2 of the above embodiment may be configured to perform a third disaster prevention process. While any specific implementation method may be used, for example, a locking device for locking or unlocking the door 7 of the living area 8 in FIG. 1 may be provided, and the locking device may be configured to be controllable from the indicator light device 2 side, and the output unit 242 of the indicator light device 2 may lock or unlock the door 7 of the living area 8 using the locking device. Specifically, in light of the need for rapid evacuation in the event of a fire, the door 7 of the living area 8 may be unlocked by controlling the locking device when SA3 in FIG. 6 or SB3 in FIG. 7 is executed, for example. Furthermore, in light of the need to prevent fraud such as theft from taking advantage of the confusion caused by a fire, the door 7 of a living area 8 that is relatively close to the fire source (for example, a living area 8 three or more floors away from the living area 8 that is the fire source, or a living area 8 on a floor below the living area 8) may be locked. Note that a motion sensor or the like may be provided in the living area 8, or an access control device may be provided to confirm that no user is present in the living area 8 before locking the door 7. Furthermore, when it is confirmed using a motion sensor or an access control device that no resident is present inside the living area 8 that is the source of the fire, the door 7 may be locked to prohibit entry into the living area 8 that is the source of the fire from the outside. In this configuration, locking or unlocking the first living area (e.g., living area 81) with the locking device can, for example, promote evacuation by unlocking it, or prohibit entry by locking it, thereby improving disaster prevention capabilities. Furthermore, for example, crime prevention in the event of an abnormality can be improved.

[0084] (Regarding the fourth disaster prevention measure) Furthermore, the indicator light device 2 of the above embodiment may be configured to perform a fourth disaster prevention process. While any specific implementation method may be used, for example, the above-mentioned recording device (for example, a device realized using technology such as a so-called smart speaker) may be provided in the living area 8 of Fig. 1, and the recording device may be configured to record utterances related to waking up or going to bed (for example, utterances such as "Good morning, boil water," "Good morning, turn on the music," "Good night, turn off the lights," etc.), the time of utterance, etc., and the output unit 242 of the indicator light device 2 may then refer to the recorded information to estimate the current state of the occupant and output an alarm according to the estimated state of the occupant. Specifically, for example, the resident's average wake-up time and average bedtime may be determined based on phrases such as "good morning" and "good night" and the time at which they are spoken. When executing SA3 of FIG. 6 or SB3 of FIG. 7, the current time may be obtained from a timing device (e.g., a timer) and compared with the determined average wake-up time and average bedtime to determine whether the resident is currently awake or asleep. Based on the determination result, the display unit 22 may be illuminated. Although this is optional, for example, if the resident is asleep, the display unit 22 may be illuminated to be more noticeable than if the resident is awake, since there is a possibility that the resident in the living area 8 may not notice the fire and may be late in escaping. Furthermore, in combination with the technology described in "(Information Output (Part 2))," information such as "The resident may be asleep. Please rescue immediately" may be displayed as text or image information when the resident is asleep. In this configuration, the current state of the resident can be estimated by referring to the information recorded in the recording device, and an alarm can be issued according to the estimated state of the resident, thereby making it possible to, for example, appropriately carry out rescue operations according to the state of the resident. In particular, it becomes possible to, for example, grasp that a resident is in a state requiring prompt rescue, and to carry out rescue operations with priority.

[0085] (Regarding indicator light devices) In addition, in the above embodiment, the indicator light device 2 is described as being provided on the outer surface of the door 7 of the living area 8 and emitting light toward the outside of the living area 8 to output display warning information or abnormality occurrence information, but this is not limited to this. The indicator light device 2 may be provided only on the inner surface of the door 7 of the living area 8 and emitting light toward the inside of the living area 8 to output each piece of information, or the indicator light device 2 may be provided on both the outer and inner surfaces of the door 7 of the living area 8 and emitting light toward both the outside and inside of the living area 8 to output each piece of information.

[0086] (Regarding restoration judgment) Furthermore, in SA4 of Fig. 5 in the above embodiment, the case where restoration is determined based on the restoration signal output by the disaster prevention receiver is exemplified, but this is not limited to this. For example, a small-scale system without a disaster prevention receiver may be envisioned. In this case, for example, when the detector that triggered the alarm is restored (when the smoke concentration falls below the threshold), the detector may output a detector-side restoration signal, and restoration may be determined based on this detector-side restoration signal. Furthermore, for example, restoration may be determined based on whether a restoration operation has been performed on the residential fire alarm that triggered the alarm.

[0087] (Regarding abnormalities and determination methods) Furthermore, the aforementioned "abnormality" may be a concept that includes, for example, a gas leak, carbon monoxide generation, intrusion of a suspicious person, high temperature and humidity, low temperature and humidity, etc., in addition to a fire. Specifically, a gas sensor, a human presence sensor, a temperature sensor, or a humidity sensor may be provided in the living area, and when the determination means detects a gas leak or carbon monoxide generation based on the detection result of the gas sensor, it may determine that an abnormality has occurred. In this case, the output means may output information identifying the gas leak or carbon monoxide generation as display alarm information. Furthermore, when the determination means detects intrusion of a suspicious person based on the detection result of the human presence sensor, it may determine that an abnormality has occurred. In this case, the output means may output information identifying the intrusion of the suspicious person as display alarm information. Furthermore, when the determination means detects high temperature and humidity based on the detection results of the temperature sensor and the humidity sensor, it may determine that an abnormality has occurred. In this case, the output means may output information to warn about heatstroke as display alarm information. In addition, if the determination means detects low temperature and low humidity based on the detection results of the temperature sensor and humidity sensor, it may determine that an abnormality has occurred, and in this case, the output means may output information to warn about influenza or a cold as display warning information.

[0088] (Communication methods) Furthermore, the communication method between the indicator light devices 2 in Figure 2 and the communication method between the sensor 1 and the indicator light device 2 are arbitrary, and for example, they may be configured to perform wired communication or wireless communication.

[0089] (Features) Furthermore, the features of the embodiments and the features of the modifications may be combined in any manner.

[0090] (Addendum)

[0091] The disaster prevention system of Appendix 1 comprises a determination means for determining whether an abnormality has occurred in a first residential area among a plurality of residential areas, and an output means for outputting display alarm information via a first alarm device that issues an alarm for at least the first residential area when the determination means determines that an abnormality has occurred in the first residential area, and the output means performs disaster prevention processing, which is processing related to disaster prevention in the first residential area, in cooperation with another device different from the first alarm device.

[0093] The disaster prevention system of Appendix 3 is the disaster prevention system described in Appendix 2, in which the output means performs the disaster prevention process of outputting, via the second alarm device, residential area identification information, which is information identifying the first residential area in which the determination means has determined that an abnormality has occurred.

[0094] The disaster prevention system of Appendix 4 is a disaster prevention system according to Appendix 2 or 3, in which the abnormality occurrence information is output from the second alarm device in a manner different from the display alarm information output via the first alarm device.

[0095] The disaster prevention system of Appendix 5 is the disaster prevention system described in Appendix 4, wherein the output means outputs the abnormality occurrence information from the second alarm device in a lighting mode different from the display alarm information output via the first alarm device.

[0096] The disaster prevention system of Appendix 6 is a disaster prevention system described in any one of Appendixes 1 to 5, wherein the other device includes a locking device that locks or unlocks the first living area, and the output means performs the process of locking or unlocking the first living area using the locking device as the disaster prevention process.

[0097] The disaster prevention system of Appendix 7 is a disaster prevention system described in any one of Appendixes 1 to 6, wherein the other device includes a recording device that records information about the resident of the first residential area, and the output means performs the disaster prevention process by referring to the information recorded in the recording device to estimate the current state of the resident and issuing an alarm according to the estimated state of the resident.

[0098] The disaster prevention system of Supplementary Note 8 is the disaster prevention system according to any one of Supplementary Notes 1 to 7, wherein the output means causes the first alarm device to emit light and outputs the display alarm information.

[0099] The disaster prevention system of Appendix 9 is a disaster prevention system described in any one of Appendixes 1 to 8, wherein at least a part of the alarm output means of the first alarm device is provided outside the first living area, and the output means outputs the display alarm information from the alarm output means of the first alarm device.

[0100] The disaster prevention system of Supplementary Note 10 is the disaster prevention system according to any one of Supplementary Notes 1 to 9, wherein the abnormality is a fire.

[0101] (Effect of supplementary notes) According to the disaster prevention system described in Appendix 1, by working in cooperation with other devices different from the first alarm device to perform disaster prevention processing, which is processing related to disaster prevention in the first residential area, it is possible to perform disaster prevention processing from all angles, rather than just processing related to a single alarm by the first alarm device, for example, thereby enabling disaster prevention to be carried out from multiple angles and improving disaster prevention capabilities.

[0102] According to the disaster prevention system described in Appendix 2, by outputting abnormality occurrence information via a second alarm device that issues an alarm for at least the second residential area, it is possible to, for example, notify the second residential area of ​​the occurrence of an abnormality, and therefore, for example, to notify residents in the vicinity of the first residential area where the abnormality was detected of the occurrence of the abnormality, so that necessary disaster prevention measures (for example, fire extinguishing, rescue, etc.) can be taken quickly.

[0103] According to the disaster prevention system described in Supplementary Note 3, by outputting residential area identification information via a second alarm device that issues an alarm for at least the second residential area, it is possible to, for example, notify the second residential area of ​​the source of the abnormality, and therefore, for example, to notify residents, etc., who live near the first residential area where the abnormality was detected of the source of the abnormality, and enable them to quickly take necessary disaster prevention measures (for example, firefighting, rescue, etc.). In particular, since it is possible to identify the source of the abnormality, if evacuation is necessary, it is possible to quickly evacuate to a safe direction (for example, a direction that avoids the source of the abnormality, etc.).

[0104] According to the disaster prevention system described in Supplementary Note 4, by outputting abnormality occurrence information from the second alarm device in a manner different from the display alarm information output via the first alarm device, it is possible to output information about the abnormality not only from the first alarm device but also from the second alarm device, making it possible to widely notify an abnormality in the first living area. Furthermore, for example, since the manner of information is different between the first alarm device and the second alarm device, it is possible to notify whether an abnormality has actually occurred in the living area, and it becomes possible to quickly take the necessary disaster prevention measures (for example, fire extinguishing, rescue, etc.).

[0105] According to the disaster prevention system described in Supplementary Note 5, by outputting display alarm information from the second alarm device in a different light emission mode from the first alarm device, for example, information regarding an abnormality can be output by light emission not only from the first alarm device but also from the second alarm device, making it possible to widely notify an abnormality in the first residential area. Furthermore, for example, since the light emission modes of information from the first alarm device and the second alarm device are different, it is possible to notify whether an abnormality is actually occurring in the residential area, and it becomes possible to promptly take necessary disaster prevention measures (e.g., fire extinguishing, rescue, etc.). Furthermore, since an alarm can be reliably issued even at night, for example, disaster prevention capabilities can be improved. Furthermore, for example, even when an abnormality occurs and causes confusion and chaos in the surrounding area, the alarm can be reliably recognized visually.

[0106] According to the disaster prevention system described in Supplementary Note 6, by locking or unlocking the first living area with the locking device, for example, it is possible to promote evacuation by unlocking or prohibit entry by locking, thereby improving disaster prevention capabilities. In addition, it is possible to improve crime prevention capabilities when an abnormality occurs, for example.

[0107] According to the disaster prevention system described in Supplementary Note 7, by referencing the information recorded in the recording device to estimate the current state of the resident and issuing an alarm according to the estimated state of the resident, it becomes possible to, for example, appropriately carry out rescue etc. according to the state of the resident. In particular, it becomes possible to, for example, grasp that a resident is in a state requiring prompt rescue, and to carry out rescue activities on a priority basis.

[0108] According to the disaster prevention system described in Supplementary Note 8, by illuminating the first alarm device and outputting the display alarm information, it is possible to reliably issue an alarm even at night, for example, thereby improving disaster prevention capabilities. Furthermore, even if an abnormality occurs and causes confusion and chaos in the surrounding area, it is possible to reliably recognize the alarm through vision.

[0109] According to the disaster prevention system described in Appendix 9, at least a part of the alarm output means of the first alarm device is provided outside the first living area, so that, for example, the occurrence of an abnormality can be reliably notified to those outside the first living area, thereby enabling those in the vicinity of the first living area to quickly take the necessary disaster prevention measures (for example, fire extinguishing, rescue, etc.).

[0110] According to the disaster prevention system described in Appendix 10, since the abnormality is a fire, it is possible to perform fire disaster prevention processing from all angles, rather than just processing a single alarm by the first alarm device, for example, and therefore it is possible to perform fire disaster prevention processing from multiple angles and improve disaster prevention capabilities.
