DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a disaster prevention system according to the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the embodiment.

[0013] [Basic Concept of the Embodiment] First, a basic concept of the embodiment will be described. The embodiment generally relates to a disaster prevention system.

[0014] 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 for performing disaster prevention processing in a general-purpose system (for example, a system including a computer that is used for general purposes), etc. This disaster prevention system includes, for example, a determination means and an output means.

[0015] 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" is something that is different from normal, and is a concept that includes, for example, fire, gas leakage, and the like. A "residential area" is an area where residents live, and is a concept that includes, for example, each dwelling unit in a collective housing such as an apartment or condominium, temporary housing, housing for disaster victims, each detached house in a housing complex, and group homes (for example, housing in which multiple care recipients and caregivers live together), or each of these dwelling units or rooms. 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, one dwelling unit or house, and multiple dwelling units or houses. 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, a specific example similar to the "first residential area".

[0016] The "output means" is 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 including, for example, making the first alarm device emit light and outputting display alarm information, and is also a concept including a means for outputting abnormality occurrence information from a second alarm device in a mode different from the display alarm information output via the first alarm device, and is also a concept including a means for outputting display alarm information from the alarm output means of the first alarm device. The "abnormality occurrence information" will be described later.

[0017] The term "display alarm information" refers to information about an abnormality, specifically, information output to the outside or inside of the residential area, for example, information output via a first alarm device that is an alarm device in the residential area where an abnormality has been determined, and information that can be visually recognized, including, for example, information shown by light emission, images, text, etc. The term "display alarm information" refers to, for example, information for notifying the occurrence of an abnormality, and the like. The term "abnormality occurrence information" refers to information about an abnormality, specifically, information output to the outside or inside of the residential area, for example, information output via a second alarm device that is an alarm device other than the first alarm device, and information that can be visually recognized, including, for example, information shown by light emission, images, text, etc. The term "abnormality occurrence information" refers to, for example, information that specifies that the determination means has determined that an abnormality has occurred in the first residential area, and the like. The display alarm information and the abnormality occurrence information may be output by the output means in the same manner as each other, or in different manners from each other. 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 (e.g., light emission) may be output in different modes (e.g., with different light emission timing, blinking speed, or light emission intensity).

[0018] 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 part 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, and outputs text. 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 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). The term "alarm output means" refers to a part of the first alarm device, and is a concept that includes, for example, some parts for outputting information (the alarm output means of the second alarm device described later is also considered to have a similar concept).

[0019] In addition, "other devices" refers to devices 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, and a recording device.

[0020] 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 part 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 as an example, a device that emits light, outputs images, and outputs text, etc. Furthermore, the term "second alarm device" refers to, for example, a device associated with the second living area, and is a concept that includes, for example, a device 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).

[0021] The term "locking device" refers to a device that locks or unlocks the first residential area, and is, for example, a different type of device from the first alarm device, and is a concept that includes devices that are realized using a known technology such as an electric lock device. The term "recording device" refers to a device that records information about the resident of the first residential 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 an utterance from a resident and performs any processing (for example, control of home appliances, etc.) based on the received utterance, and is a concept that includes devices that record information about the utterance as information about the resident, and is, for example, a concept that includes devices that are realized using a technology such as a so-called smart speaker. The term "information about the resident of the first residential area" refers to a concept that includes, for example, information about the time of the utterance, the content of the utterance, and environmental information at the time of the utterance (room temperature, humidity, or outdoor weather, etc.) when a resident living in the first residential area speaks to the recording device.

[0022] In addition, "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.

[0023] The term "disaster prevention processing" refers to processing related to disaster prevention in the first residential area, specifically processing performed in cooperation with other measures, and is a concept including, for example, the first to fourth disaster prevention processings. The term "first disaster prevention processing" refers to processing performed in cooperation with the second alarm device, and is a concept including, for example, processing of outputting abnormality occurrence information, which is information specifying that the determination means has determined that an abnormality has occurred in the first residential area, via the second alarm device. The term "second disaster prevention processing" refers to processing performed in cooperation with the second alarm device, and is a concept including, for example, processing of outputting residential area identification information, which is information specifying the first residential area in which the determination means has determined that an abnormality has occurred, via the second alarm device. The term "third disaster prevention processing" refers to processing performed in cooperation with a locking device, and is a concept including, for example, processing of locking or unlocking the first residential area using the locking device. The "fourth disaster prevention processing" is processing performed in cooperation with a recording device, and is a concept that includes, for example, processing of estimating the current condition of the resident by referring to information recorded in a recording device and issuing an alert according to the estimated condition of the resident.

[0024] In the following embodiment, the first disaster prevention processing 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 processing will be described in the modified example.

[0025] [Specific details of the embodiment] Next, the specific contents of the embodiment will be described.

[0026] (composition) First, the configuration of the disaster prevention system according to the present embodiment will be described. Fig. 1 is a diagram showing a living area to which the disaster prevention system according to the present 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 81-83 as representatives. These living areas 81-83 will be collectively referred to as "living area 8" (the same applies to the detector 1, indicator light device 2, and door 7) except when they are described separately from one another.

[0027] The disaster prevention system 900 in FIG. 2 includes, for example, a sensor 1 and an indicator light device 2.

[0028] (Configuration-sensor) 1, and is, for example, a device that performs wireless communication with an external device (for example, the indicator light device 2). The sensor 1 also includes, for example, a sensor 111 that detects a fire in the living area 81, a sensor 121 that detects a fire in the living area 82, and a sensor 131 that detects a fire in the living area 83. The specific type and configuration of the sensor 1 are arbitrary, but for example, the sensor 1 may be installed in the living area 8 in FIG. 1, and may be configured to include a means for detecting a fire by detecting smoke generated by a fire, wireless communication means, and the like.

[0029] (Configuration-indicator light device) The indicator light device 2 is an alarm device and is installed, for example, at 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 living area 81 at the door 71. The indicator light device 2 also includes an indicator light device 201 installed at the door 71 of the living area 81, an indicator light device 202 installed at the door 72 of the living area 82, and an indicator light device 203 installed at 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.

[0030] (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, for example, using a known wireless communication circuit or the like.

[0031] (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, the display unit 22 may 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 where the entire display unit 22 is provided outside the living area 8 will be described, but the display unit 22 may be configured to be provided outside the living area 8 only in part.

[0032] (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 indicator light device 2, and is configured using, for example, a flash memory (not shown) as an external recording device. However, instead of or together with the flash memory, any other recording medium including a magnetic recording medium such as a hard disk or a magnetic disk, or an optical recording medium such as a DVD or a Blu-ray disk can be used. As shown in Fig. 2, the recording unit 23 stores an indicator light device ID, map information, residential area related information, and operating condition information.

[0033] (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 of 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, living area related information, and operating condition information). For example, "ID201" is recorded in the recording unit 23 of the indicator light device 201 as the "indicator light device ID", "ID202" is recorded in the recording unit 23 of the indicator light device 202 as the "indicator light device ID", and "ID203" is recorded in the recording unit 23 of the indicator light device 203 as the "indicator light device ID".

[0034] (Configuration - Indicator light device - Recording unit - Map information) "Map information" is information that identifies a map capable of identifying the position of each residential area 8, including residential areas 81 to 83 in Figure 1, and is, for example, information capable of identifying the position of each residential area 8 based on any reference object (e.g., a center line, wall, beam, or pillar, etc.) of the building of residential area 8 (e.g., an apartment building that is a condominium), or the floor number or plan coordinates indicating the position of a component (e.g., door 7, etc.) set in each residential area.

[0035] (Configuration - Indicator light device - Recording unit - Living area related information) "Residential area related information" is information related to residential area 8, and is, for example, information that identifies a device installed in residential area 8 or the location of residential area 8. FIG. 4 is a diagram illustrating residential area related information. As shown in FIG. 4, the residential area related information stores, for example, items "residential area ID", "sensor ID", "indicator light device ID", and "location information" in association with information corresponding to each item. Information corresponding to the item "residential area ID" is a residential area ID that uniquely identifies a residential area (in FIG. 4, "ID81" as the residential area ID of residential area 81 in FIG. 1, "ID82" as the residential area ID of residential area 82, and "ID83" as 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 described 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 identifies the location of the residential area 8. As this location information, information that enables the relative location relationship between each residential area 8 (for example, the distance between each residential area 8, etc.) to be identified by referring to the map information in FIG. 2 is stored. 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 of the residential areas 8 from information such as "Room 101" to "Room 103".

[0036] (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, an item "status information" and an item "light emission mode information" in association with information corresponding to each item.

[0037] The information corresponding to the item "status information" is status information that specifies a 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.

[0038] The "coordination 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, and for example corresponds to the first alarm device and indicates an indicator light device 2 installed in a living area 8 where a fire has been detected. The "coordination 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, and for example corresponds to the second alarm device and indicates an indicator light device 2 installed in a living area 8 where no fire has been detected.

[0039] In FIG. 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 it 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 it 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 positions relative to the coordination source device, and "1" to "3" indicate that they are on the same floor as the coordination source device, and the larger the numerical value, the further away they are, and "4" indicates that they are not on the same floor as the coordination source device. Regarding "1" to "3" in more detail, "1" indicates that the installation location of the destination 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 destination device corresponds to the residential area 8 that is two areas next to the residential area 8 in which the source device is installed, and "3" indicates that the installation location of the destination device corresponds to the residential area 8 that is three or more areas next to the residential area 8 in which the source device is installed.

[0040] The information corresponding to the item "light emission mode information" is light emission mode information that specifies the light emission mode of the display unit 22. This light emission mode information is arbitrary, but for example, in FIG. 4, the light emission mode is specified as the light intensity and the blinking speed (time interval of blinking), and for example, the stronger the light intensity and the faster the blinking speed, the closer to the fire source is indicated. In detail, the light intensity and the blinking speed are each set in five stages, and a case where "intensity: 5, speed: 5" in FIG. 5 is recorded will be described as an example. Note that "intensity: 5, speed: 5" specifies that the light intensity is an intensity corresponding to "5" and that the blinking speed is a speed corresponding to "5". In addition, the numerical values ​​of the light intensity and blinking speed exemplified in FIG. 5 indicate that the intensity is stronger and the blinking speed is faster as the values ​​are larger. The specific values ​​of these intensities and blinking speeds are arbitrary, but for example, "intensity: 5, speed: 5" indicates that the light is about "7000 lumens to 8000 lumens" and blinks at intervals of about "0.5 to 1 second," and "intensity: 4, speed: 4" indicates that the light is about "6000 lumens to 6500 lumens" and blinks at intervals of about "2 to 3 seconds."

[0041] (Configuration - Indicator light device - Control unit) 2 is a control means for controlling the indicator light device 2, and specifically, is 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 realize specific functions), and an internal memory such as a RAM for storing the programs and various data. In particular, the program according to the embodiment is installed in the indicator light device 2 via any recording medium or network, thereby substantially configuring each part of the control unit 24.

[0042] 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 of ​​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 about at least the first living area, when the determination unit 241 determines that an abnormality has occurred in the first living area, and 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 part of this control unit 24 will be described later.

[0043] (process) Next, a description will be given of the coordination source side disaster prevention processing and the coordination destination side disaster prevention processing executed by the thus configured disaster prevention system 900. Here, for example, each of the indicator light devices 2 in Fig. 1 functions as a coordination source device or a coordination destination device depending on the location of a fire, and therefore executes both the coordination source side disaster prevention processing and the coordination destination side disaster prevention processing, but a case will be described in particular where a fire breaks out in the living area 81, the indicator light device 201 functions as the coordination source device, and the indicator light devices 202 and 203 function as coordination destination devices.

[0044] (Processing - Disaster prevention processing on the cooperation source side) First, the disaster prevention process on the coordination source side will be described. Fig. 6 is a flowchart of the disaster prevention process on the coordination source side (in the following description of each process, steps are abbreviated as "S"). The "disaster prevention process on the coordination source side" is, in general, a process executed by the indicator light device 2, and more specifically, a process for detecting the occurrence of a fire and operating as a coordination source device. The timing for executing this disaster prevention process on the coordination source side is arbitrary, but for example, when each device of the disaster prevention system 900 is powered on, it is started up and starts execution, and the description will begin from the point where execution starts (the same applies to the disaster prevention process on the coordination destination side).

[0045] In SA1 of FIG. 6, the determination unit 241 determines whether or not a fire has occurred. Although the specific details are arbitrary, for example, the detector 1 outputs an alarm signal when it detects the occurrence of a fire, and the determination unit 241 monitors the communication unit 21 to determine whether or not the alarm signal has been received. If the alarm signal has not been received, it is determined that a fire has not occurred (NO in SA1), and SA1 is repeatedly executed until it is determined that a fire has occurred. If the alarm signal has been received, it is determined that a fire has occurred (YES in SA1), and the process proceeds to SA2. Here, for example, if a fire has occurred in the living area 81, the detector 111 detects the occurrence of a 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.

[0046] In SA2 in Fig. 6, the output unit 242 determines the light emission mode. Specifically, the output unit 242 refers to the operating condition information in Fig. 5, acquires light emission mode information whose status information is "cooperation 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, for example, by referring to the operating condition information in Fig. 5, the output unit 242 of the indicator light device 201 acquires "intensity: 5, speed: 5" which is light emission mode information whose status information is "cooperation source", and determines that the light emission mode of the indicator light device 201 is to blink the light of the intensity corresponding to "5" at the blinking speed corresponding to "5".

[0047] In SA3 in Fig. 6, the output unit 242 starts outputting the display warning information by starting light emission. Specifically, although any method is used, for example, the light emission mode determined in SA2 is specified, and light emission in the determined light emission mode is started in the display unit 22 in Fig. 3. Here, for example, the output unit 242 of the indicator light device 201 specifies the light emission mode corresponding to "intensity: 5, speed: 5" which is the light emission mode determined in SA2, and light emission in the light emission mode corresponding to the determined "intensity: 5, speed: 5" is started in the display unit 22 in Fig. 3. In this case, the display unit 22 of the indicator light device 201 starts blinking so as to repeatedly output light of about "7000 lumens to 8000 lumens" at intervals of about "0.5 seconds to 1 second".

[0048] In SA4 in 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. The specifics of SA4 are arbitrary, but for example, the output unit 242 may obtain the indicator light device ID recorded in its own recording unit 23, add the obtained 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. Then, this alarm relay signal reaches, for example, surrounding indicator light devices 2.

[0049] 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, generates an alarm relay signal by adding the acquired "ID201" as the indicator light device ID of the cooperation source device, and transmits the generated alarm relay signal. Then, this alarm relay signal reaches, for example, the indicator light device 202, which is the surrounding indicator light device 2.

[0050] In SA5 of FIG. 6, the determination unit 241 determines whether or not the system has been restored. Specifically, although this is arbitrary, for example, when a predetermined operation (operation for restoring) is performed on a disaster prevention receiver (not shown), the disaster prevention receiver outputs a restoration signal, and the determination unit 241 monitors the communication unit 21 to determine whether or not the restoration signal is received. Then, when the restoration signal is not received, it is determined that the system has not been restored (NO in SA5), and SA5 is repeatedly executed until it is determined that the system has been restored. Also, when a restoration signal is received, it is determined that the system has been restored (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 restoration signal, and the determination unit 241 of the indicator light device 201 receives the restoration signal and determines that the system has been restored.

[0051] In SA6 in Fig. 6, the output unit 242 ends the output of the display warning information by ending the light emission. Specifically, the light emission is ended by turning off the display unit 22 in Fig. 3, although this is arbitrary. Here, for example, the output unit 242 of the indicator light device 201 ends the blinking of a light of about "7000 lumens to 8000 lumens" on the display unit 22 of the indicator light device 201 at intervals of about "0.5 seconds to 1 second".

[0052] 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 including at least the indicator light device ID of the coordination source device. The specifics of SA7 are arbitrary, but for example, it is similar to the case of SA4, in which the indicator light device ID recorded in its own recording unit 23 is obtained, the obtained indicator light device ID is added as the indicator light device ID of the coordination source device to generate a restoration relay signal, and the generated restoration relay signal is transmitted. Then, this restoration relay signal reaches, for example, the surrounding indicator light devices 2.

[0053] 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, generates a restoration relay signal by adding the acquired "ID201" as the indicator light device ID of the coordination source device, and transmits the generated restoration relay signal. Then, this restoration relay signal 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.

[0054] (Processing - Disaster prevention processing on partner side) Next, the disaster prevention process on the cooperation destination side will be described. Fig. 7 is a flowchart of the disaster prevention process on the cooperation destination side. The "disaster prevention process on the cooperation destination side" is generally a process executed by the indicator light device 2, and specifically, a process for operating as a cooperation destination device based on communication with the cooperation source device.

[0055] In SB1 of FIG. 7, the control unit 24 judges whether or not it has received an alarm relay signal transmitted by another indicator light device 2 as a cooperation source device. Specifically, the control unit 24 monitors the communication unit 21, acquires the indicator light device ID of the cooperation source device contained in the alarm relay signal received by the communication unit 21, and acquires the indicator light device ID of its own recording unit 23, and judges whether or not the acquired indicator light device IDs match. Then, if the indicator light device IDs match each other, it determines that the alarm relay signal received by the communication unit 21 is an alarm relay signal transmitted by itself as a cooperation source device relayed by another indicator light device 2, and judges that the alarm relay signal has not been received (NO in SB1), and repeatedly executes SB1 until it is determined that the alarm relay signal has been received. Also, if the indicator light device IDs do not match each other, it determines that the alarm relay signal received by the communication unit 21 is an alarm relay signal transmitted by another indicator light device 2 as a cooperation source device, and judges that the alarm relay signal has been received (YES in SB1), and moves 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 its own recording unit's indicator light device ID "ID202" do not match each other, and it determines that an alarm relay signal has been received.

[0056] In SB2 of Fig. 7, the control unit 24 determines the light emission mode. Specifically, it is arbitrary, but for example, since the indicator light device 2 itself has not determined that a fire has occurred (that is, another indicator light device 2 has determined that a fire has occurred), it will operate as a coordination destination device, and specifically, it refers to the operating condition information of Fig. 5 to acquire "coordination destination 1" to "coordination destination 4" of the status information. Next, it refers to the living area related information of Fig. 4 to acquire the position information corresponding to the indicator light device ID of the coordination source device included in the alarm relay signal acquired in SB1 and the position information corresponding to its own indicator light device ID, and then refers to the map information of the recording unit 23 of Fig. 2 to specify the relative positional relationship between the living area 8 corresponding to the aforementioned acquired position information of the coordination source device and the living area 8 corresponding to its own position information (that is, the position information of the coordination destination device). Next, one piece of status information corresponding to the identified relative positional relationship is selected from the previously acquired "associated destination 1" to "associated destination 4," and light emission mode information corresponding to the selected state information is acquired in the operating condition information of Figure 5. The light emission mode specified by the acquired light emission mode information is determined as the light emission mode of the indicator light device 2.

[0057] Here, for example, the control unit 24 of the indicator light device 202 acquires the status information "Cooperation destination 1" to "Cooperation destination 4" with reference to the operating condition information in Fig. 5. Next, with reference to the residential area related information in Fig. 4, it acquires "Room 101" as the location information corresponding to "ID201", which is the indicator 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 indicator light device ID, and then, with reference to the map information in the recording unit 23 in Fig. 2, it specifies 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 link destination device corresponds to the residential area 82 adjacent to the residential area 81 in which the link source device is installed, "Link destination 1" is selected from the previously acquired "Link destination 1" to "Link destination 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 "Link destination 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 flash speed corresponding to "4".

[0058] At SB3 in Fig. 7, the control unit 24 starts outputting abnormality occurrence information by starting light emission. Specifically, although this is arbitrary, for example, the light emission mode determined at SB2 is specified, and light emission in the determined light emission mode is started on the display unit 22 in Fig. 3. Here, for example, the control unit 24 of the indicator light device 202 specifies the light emission mode corresponding to "intensity: 4, speed: 4" which is the light emission mode determined at SB2, and light emission in the light emission mode corresponding to the determined "intensity: 4, speed: 4" is started on the display unit 22 in Fig. 3. In this case, the display unit 22 of the indicator light device 202 starts blinking so as to repeatedly output light of about "6000 lumens to 6500 lumens" at intervals of about "2 seconds to 3 seconds".

[0059] In SB4 in Fig. 7, the control unit 24 cooperates with other indicator light devices 2 by transmitting and relaying an alarm relay signal. Specifically, the control unit 24 transmits and relays the alarm relay signal received in SB1, for example, although this is arbitrary. Then, this alarm relay signal reaches, for example, a surrounding indicator light device 2. Here, for example, the control unit 24 of the indicator light device 202 transmits and relays an alarm relay signal including "ID201" as the indicator light device ID of the cooperation source device. Then, this alarm relay signal reaches, for example, the indicator light device 203, which is the surrounding indicator light device 2.

[0060] In SB5 of FIG. 7, the control unit 24 judges whether or not it has received a return relay signal transmitted by another indicator light device 2 as a cooperation source device. Specifically, although it is arbitrary, for example, it monitors the communication unit 21, acquires the indicator light device ID of the cooperation source device contained in the return relay signal received by the communication unit 21, and acquires the indicator light device ID of the cooperation source device contained in the alarm relay signal acquired by SB1, and judges whether or not these acquired indicator light device IDs match. Then, if the indicator light device IDs do not match each other, it judges that the return relay signal received by the communication unit 21 does not correspond to the alarm relay signal received by SB1, and judges that the return relay signal has not been received (NO in SB5), and repeatedly executes SB5 until it judges that the return relay signal has been received. Also, if the indicator light device IDs match each other, it judges that the return relay signal received by the communication unit 21 corresponds to the alarm relay signal received by SB1, and judges 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 including "ID201", since the alarm relay signal received at SB1 also contains "ID201", these match and it is determined that a return relay signal has been received.

[0061] In 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 return relay signal received in SB5 is transmitted and relayed. This return relay signal then reaches, for example, a surrounding indicator light device 2. Here, for example, the control unit 24 of the indicator light device 202 transmits and relays a return relay signal including "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 surrounding indicator light device 2.

[0062] At SB7 in Fig. 7, the control unit 24 ends the output of the abnormality occurrence information by ending the light emission. Specifically, this is arbitrary, but for example, the light emission is ended 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 blinking 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.

[0063] (Processing-operation example) Next, an operation example of the disaster prevention system 900 will be described. Here, for example, as described above, an operation example will be described when a fire breaks out in the living area 81 in Fig. 1. 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.

[0064] On the other hand, the indicator light device 202 receives the alarm signal, determines a light emission mode corresponding to "intensity: 4, speed: 4" in SB2 after YES in SB1 in Fig. 7, 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, determines a light emission mode corresponding to "intensity: 3, speed: 3" in SB2 after YES in SB1 in Fig. 7, starts emitting light in the determined mode in SB3, and relays an alarm relay signal to SB4.

[0065] Furthermore, a user outside the living area 8 (e.g., a resident or a firefighter) can visually recognize the light emitted by the display unit 22 of each indicator light device 2 and, based on the intensity of the emitted light or the flashing rate, recognize that a fire has occurred and that the source of the fire is the living area 81, and can take the necessary measures.

[0066] Thereafter, when a predetermined operation is performed on a disaster prevention receiver (not shown), the indicator light device 201 stops emitting light at SA5 after SA5 in Fig. 6, and then transmits a recovery relay signal at SA7. Meanwhile, the indicator light device 202 receives the recovery relay signal, transmits a recovery relay signal at SB6 after YES at SB5 in Fig. 7, and then stops emitting light at SB7. Meanwhile, the indicator light device 203 also performs the same process as the indicator light device 202, and stops emitting light at SB7. This concludes the explanation of this operational example.

[0067] (Effects of the embodiment) Thus, according to this embodiment, by performing disaster prevention processing, which is processing related to disaster prevention in the first living area (e.g., living area 81), in cooperation with other devices (e.g., indicator light devices 202, 203) different from the first alarm device (e.g., indicator light device 201), 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, thereby enabling disaster prevention to be carried out from multiple angles and improving disaster prevention capabilities.

[0068] Furthermore, by outputting abnormality 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 ​​the occurrence of an abnormality, such as a fire, and therefore it is possible to notify residents near the first living area where a fire has been detected of the abnormality, so that necessary disaster prevention measures (e.g., fire extinguishing, rescue, etc.) can be taken quickly.

[0069] Also, 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, for example, information regarding the abnormality can be output 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. Also, 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 is actually occurring in the living area, making it possible to quickly take measures necessary for disaster prevention (for example, firefighting, rescue, etc.).

[0070] In addition, by outputting display alarm information from the second alarm device in a different light emission mode from the first alarm device, for example, information on an abnormality can be output by light emission not only from the first alarm device but also from the second alarm device, so that an abnormality in the first residential area can be notified over a wide area. In addition, for example, since the light emission modes of information are different between the first alarm device and the second alarm device, it is possible to notify whether or not an abnormality actually occurs in the residential area, and it is possible to promptly take measures necessary for disaster prevention (for example, fire extinguishing, rescue, etc.). In addition, since an alarm can be reliably issued even at night, for example, it is possible to improve disaster prevention capabilities. In addition, for example, even when an abnormality occurs and causes confusion and chaos in the surrounding area, it is possible to reliably recognize the alarm through vision.

[0071] Moreover, by illuminating the first alarm device and outputting the display alarm information, an alarm can be issued reliably even at night, for example, and disaster prevention can be improved. Also, for example, even if a fire breaks out and causes chaos in the surrounding area, the alarm can be reliably recognized visually.

[0072] Furthermore, since the display unit 22 is provided outside the living area 8, it can reliably notify people outside the living area 8 of the occurrence of an abnormality, enabling those in the vicinity of the living area 8 to quickly take necessary disaster prevention measures (for example, fire extinguishing, rescue, etc.).

[0073] [Modifications to the embodiment] Although the embodiment of the present invention has been described above, the specific configuration and means of the present invention can be modified and improved as desired within the scope of the technical ideas of each invention described in the claims. Such modifications will be described below.

[0074] (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.

[0075] (Regarding decentralization and integration) Moreover, the above-mentioned configuration is a functional concept, and does not necessarily have to be physically configured as shown in the figure. In other words, the specific form of distribution or integration of each part is not limited to that shown in the figure, and all or part of it can be functionally or physically distributed or integrated in any unit. Furthermore, the "device" in this application is not limited to one configured by a single device, but includes one configured by multiple devices. In particular, at least some of the functions of the indicator light device 2 (for example, the functions of the determination unit 241 or the output unit 242, etc.) may be provided in any device including a disaster prevention receiver not shown, and the indicator light device 2 may be controlled by the any device. In this case, the processing may be appropriately changed so that the same processing as that described in the embodiment can be performed.

[0076] (About output of information (part 1)) In the above embodiment, the light intensity and blinking speed are varied based on the operating condition information in Fig. 5 to output different information, but the present invention is not limited to this. For example, by utilizing the configuration in which each indicator light device 2 is capable of communicating with each other, the display unit 22 of each device may be blinked sequentially in each indicator light device 2 so that the user has an image of light flowing from the side of the coordination destination device far from the coordination source device toward the coordination source device. In this case, one of the indicator light devices 2 (for example, the coordination source device) may control the blinking timing of each indicator light device 2. Alternatively, the direction of the image of light flowing may be reversed to guide evacuation.

[0077] (About output of information (part 2)) Also, different information may be output by, for example, changing the color of the output light or the blinking pattern. Also, for example, as the display unit 22 in Fig. 2, a character display means for displaying text like an electronic bulletin board or an image display means for displaying images like a liquid crystal display may be provided together with or instead of the LED described above, and text information or image information may be displayed via each of these display means. In such a configuration, for example, information identifying the location of the living area 8 where the fire has occurred (for example, the floor number and name (Room 101, etc.)) may be displayed as text information or image information.

[0078] 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 is reported for a dwelling or when a fire is reported nearby), resident information related to the occupants of the dwelling in which the indicator light device 2 is installed (for example, the age of the resident, the number of residents, the level of care required by the resident, whether the resident is a person requiring assistance in the event of a disaster), or the presence or absence of dangerous objects, etc. (hazardous object presence / absence information) can be displayed.

[0079] Furthermore, for example, when outputting different information by varying the color of light that is output, as one example, an LED capable of emitting two colors, red and green, may 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) may be made to emit red light, and the indicator light devices 2 installed in the dwellings neighboring the dwelling where a fire has been reported may be made to emit green light.

[0080] Furthermore, when outputting different information by, for example, varying the blinking pattern, etc., as an example, the light emission cycle may be made the same, and different duty ratios (the ratio of the time that light is emitted to the light emission cycle) of the indicator light devices 2 installed in each dwelling unit may be made different to output different information (for example, by making the duty ratio smaller the further away from the dwelling unit where the fire alarm has been issued).

[0081] Also, for example, the light emission of the destination device may be controlled by 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 destination device may receive the predetermined signal. The destination 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 detail, 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 destination device, and the destination device may control its own light emission intensity by referring to the recorded information.

[0082] (Regarding the second disaster prevention measures) Also, the indicator light device 2 of the above embodiment may be configured to perform a second disaster prevention process. A specific implementation method is arbitrary, but 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. Note that the output method of the location information is arbitrary, but for example, in combination with the technology of "(About output of information (part 2))", location information (for example, text information such as "Room 101" or map image information showing Room 101) may be output as text information or image information. 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, for example, notify the second residential area of ​​the source of the fire, and therefore, for example, it is possible to notify the residents in the vicinity of the first residential area (e.g., residential area 81) where a fire has been detected of the source of the fire, and to have them promptly take necessary disaster prevention measures (e.g., fire extinguishing, rescue, etc.). In particular, since it is possible to identify the source of the fire, when evacuation is necessary, evacuation can be promptly carried out in a safe direction (e.g., a direction that avoids the source of the fire, etc.).

[0083] (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 approach 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). In this case, the embodiment may be interpreted as a second disaster prevention process being performed.

[0084] (Regarding the third disaster prevention measures) Also, the indicator light device 2 of the above embodiment may be configured to perform a third disaster prevention process. A specific implementation method is arbitrary, but for example, a locking device that locks or unlocks 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 by the locking device. Specifically, in the event of a fire, focusing on the need to evacuate quickly, for example, when SA3 in FIG. 6 or SB3 in FIG. 7 is executed, the locking device may be controlled to unlock the door 7 of the living area 8. In addition, focusing on the need to prevent fraud such as theft from occurring during the confusion of a fire outbreak, the door 7 of a living area 8 that is relatively far from the fire source (for example, a living area 8 that is three or more doors away from the living area 8 that is the fire source, a living area 8 on a floor below the living area 8, etc.) may be locked. In addition, a human sensor or an entrance / exit management device may be provided in the living area 8, and the door 7 may be locked after confirming that no user is present in the living area 8. In addition, when it is confirmed that no resident is present inside the living area 8 that is the source of the fire using a human sensor or an entrance / exit management device, 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, by locking or unlocking the first living area (for example, the living area 81) using the locking device, for example, evacuation can be promoted by unlocking, or entry can be prohibited by locking, so that disaster prevention can be improved. In addition, for example, crime prevention when an abnormality occurs can be improved.

[0085] (Regarding the fourth disaster prevention measure) The indicator light device 2 of the above embodiment may be configured to perform a fourth disaster prevention process. The specific implementation method is arbitrary, but for example, the above-mentioned recording device (for example, a device realized using a 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 the contents of speech related to getting up or going to bed (for example, the contents of speech such as "Good morning, boil water", "Good morning, turn on the music", "Good night, turn off the lights") and the time of speech, etc., and the output unit 242 of the indicator light device 2 may 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 average wake-up time and average bedtime of the resident may be specified based on phrases such as "good morning" and "good night" and the time of their utterance. When SA3 in FIG. 6 or SB3 in FIG. 7 is executed, the current time may be acquired from a timing means (for example, a timer, etc.) of the resident, and the acquired current time may be compared with the aforementioned specified average wake-up time and average bedtime to determine whether the resident is currently in an awake state or in a sleep state. Based on the determination result, the display unit 22 may be illuminated. Although the specific details are optional, for example, when the resident is in a sleep state, the resident in the living area 8 may not notice the fire and may be late in escaping. Therefore, the display unit 22 may be illuminated to be more noticeable than when the resident is in an awake state. In addition, in combination with the technology of "(About output of information (part 2))", information such as "The resident may be asleep. Please rescue immediately" may be displayed as text information or image information when the resident is in a sleep state. In this configuration, the current state of the resident is estimated by referring to the information recorded in the recording device, and an alarm is issued according to the estimated state of the resident, making it possible to, for example, appropriately perform rescue according to the state of the resident. In particular, it becomes possible to grasp, for example, that a resident is in a state requiring prompt rescue, and to perform rescue operations with priority.

[0086] (Regarding indicator light devices) In addition, in the above embodiment, a case has been described in which the indicator light device 2 is provided on the outer surface of the door 7 to the living area 8 and emits light toward the outside of the living area 8 to output display warning information or abnormality occurrence information, but this is not limited to the above. The indicator light device 2 may be provided only on the inner surface of the door 7 to the living area 8 and emits 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 to the living area 8 and emits light toward both the outside and inside of the living area 8 to output each piece of information.

[0087] (Decision on restoration) In addition, in SA4 in FIG. 5 of the above embodiment, the case where whether or not the alarm has been restored is determined based on the restoration signal output by the disaster prevention receiver is exemplified, but this is not limited to the above. For example, a small-scale system that does not include a disaster prevention receiver may be assumed. In this case, for example, when the alarmed detector is restored (when the smoke concentration becomes equal to or lower than the threshold), the detector may output a detector-side restoration signal, and the system may determine whether or not the alarm has been restored based on this detector-side restoration signal. Also, for example, the system may determine whether or not the alarmed residential fire alarm has been restored based on whether or not a restoration operation has been performed.

[0088] (Regarding abnormalities and judgment methods) Furthermore, the aforementioned "abnormality" may be a concept including, for example, a gas leak, carbon monoxide generation, intrusion of a suspicious person, high temperature and high humidity, low temperature and low humidity, etc., in addition to a fire. Specifically, a gas sensor, a human 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, the determination means may determine that an abnormality has occurred, and in this case, the output means may output information specifying the gas leak or carbon monoxide generation as display alarm information. Furthermore, when the determination means detects an intrusion of a suspicious person based on the detection result of the human sensor, the determination means may determine that an abnormality has occurred, and in this case, the output means may output information specifying the intrusion of the suspicious person as display alarm information. Furthermore, when the determination means detects high temperature and high humidity based on the detection results of the temperature sensor and the humidity sensor, the determination means may determine that an abnormality has occurred, and in this case, the output means may output information for calling attention to heat stroke as display alarm information. In addition, when the determination means detects low temperature and low humidity based on the detection results of the temperature sensor and the humidity sensor, it determines that an abnormality has occurred, and in this case, the output means may output information to warn about influenza or colds as display warning information.

[0089] (Communication methods) In addition, 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 they may be configured to perform wireless communication.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] (Effect of supplementary notes) According to the disaster prevention system described in Appendix 1, by performing disaster prevention processing, which is processing related to disaster prevention in the first living area, in cooperation with other devices different from the first alarm device, 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. This makes it possible to carry out disaster prevention from multiple angles and improve disaster prevention capabilities.

[0103] 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 living area, it is possible to, for example, notify the second living area of ​​the occurrence of an abnormality. Therefore, for example, it is possible to notify residents near the first living area where the abnormality has been detected of the occurrence of the abnormality, and enable them to quickly take the necessary disaster prevention measures (for example, fire extinguishing, rescue, etc.).

[0104] 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, it is possible to notify the residents in the vicinity of the first residential area in which the abnormality was determined of the source of the abnormality and to have them promptly take necessary disaster prevention measures (for example, firefighting, rescue, etc.). In particular, since it is possible to identify the source of the abnormality, when evacuation is necessary, it is possible to promptly evacuate to a safe direction (for example, a direction that avoids the source of the abnormality, etc.).

[0105] 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, for example, information related to the abnormality can be output 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. Also, 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 is actually occurring in the residential area, making it possible to quickly take necessary disaster prevention measures (for example, firefighting, rescue, etc.).

[0106] 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 on an abnormality can be output by light emission not only from the first alarm device but also from the second alarm device, so that an abnormality in the first residential area can be widely notified. In addition, for example, since the light emission modes of information are different between the first alarm device and the second alarm device, it is possible to notify whether or not an abnormality actually occurs in the residential area, and it is possible to promptly take measures necessary for disaster prevention (for example, fire extinguishing, rescue, etc.). In addition, since an alarm can be reliably issued even at night, for example, it is possible to improve disaster prevention capabilities. In addition, for example, even when an abnormality occurs and causes confusion and chaos in the surrounding area, it is possible to reliably recognize the alarm through vision.

[0107] 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 to prohibit entry by locking, thereby improving disaster prevention. In addition, it is possible to improve crime prevention when an abnormality occurs, for example.

[0108] According to the disaster prevention system described in Supplementary Note 7, by referring to the information recorded in the recording device, the current state of the resident is estimated, and an alarm is issued according to the estimated state of the resident, it becomes possible to, for example, appropriately perform rescue according to the state of the resident. In particular, it becomes possible to grasp, for example, that a resident is in a state requiring prompt rescue, and to perform rescue operations with priority.

[0109] 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, and therefore it is possible to improve disaster prevention capabilities. Also, for example, even if an abnormality occurs and causes confusion and chaos in the surrounding area, it is possible to reliably recognize the alarm through vision.

[0110] 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, enabling those in the vicinity of the first living area to quickly take necessary disaster prevention measures (for example, fire extinguishing, rescue, etc.).

[0111] According to the disaster prevention system described in Appendix 10, since the abnormality is a fire, for example, not only processing related to a single alarm by the first alarm device but also processing related to fire disaster prevention from all angles can be performed, so that fire disaster prevention can be performed from multiple angles and disaster prevention capabilities can be improved.
