Description

The present invention relates to a disaster prevention system.

Conventionally, wireless monitoring systems that monitor for abnormalities within a dwelling have been known (see, for example, Patent Document 1). In this wireless monitoring system, when an abnormality is detected within the dwelling, an outdoor indicator light installed outside is turned on to notify the user of the abnormality.

Japanese Patent Application Laid-Open No. 2006-106995

In today's aging society, there has been a demand for improved disaster prevention capabilities in dwellings for elderly people living alone, in technologies for monitoring dwellings, including the wireless monitoring system of Patent Document 1. In other words, if an abnormality (such as a fire) occurs in the dwelling of an elderly person living alone, the resident's declining physical and intellectual abilities may make it difficult for them to respond to the abnormality quickly (such as by reporting it or requesting rescue), and so there has been a demand for improved disaster prevention capabilities.

The present invention was made in consideration of the above problems, and aims to provide a disaster prevention system that can improve disaster prevention capabilities.

In order to solve the above-mentioned problems and achieve the object, the disaster prevention system described in claim 1 is a disaster prevention system comprising: a determination means that is installed inside each of a plurality of residential areas and determines whether or not an abnormality has occurred inside the residential area in which the determination means is installed; and an alarm device that is installed outside each of the residential areas in correspondence with the residential areas in which the determination means is installed, the alarm device having an output means that performs disaster prevention processing that is processing related to disaster prevention in at least the residential area when the determination means inside the residential area corresponding to the alarm device determines that an abnormality has occurred, and the output means of a first alarm device that is the alarm device corresponding to a first residential area among the plurality of residential areas outputs information indicating the presence or absence of a hazardous object in the first residential area. The disaster prevention system performs a process of outputting information indicating the presence or absence of hazardous objects in the neighboring residential area via a second alarm device, which is another alarm device provided in correspondence with a neighboring residential area of the first residential area among the plurality of residential areas , and the disaster prevention system performs a process 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 in an illumination mode corresponding to the received radio wave intensity of a signal of a predetermined strength output by the first alarm device when the signal of the predetermined strength is received by the second alarm device, and the disaster prevention system performs a process of outputting the abnormality occurrence information in an illumination mode in which the illumination intensity becomes stronger as the received radio wave strength becomes stronger .

Below, an embodiment of the disaster prevention system according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to this embodiment.

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

Here, a "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, and a system that is realized by implementing a disaster prevention processing function in a general-purpose system (for example, a system that includes a general-purpose computer, etc.). This disaster prevention system includes, for example, a determination means and an output means.

The "determination means" is a means for determining whether an abnormality has occurred in a first residential area among multiple residential areas. An "abnormality" is something that is different from normal, and is a concept that includes, for example, fires and gas leaks. A "residential area" is an area where residents reside, and is a concept that includes, for example, each dwelling unit in a multi-family housing complex such as a condominium or apartment, temporary housing, housing for disaster victims, each detached home in a housing complex, and group homes (e.g., homes where multiple care recipients and caregivers live together), as well as each dwelling unit or home. A "first residential area" is a residential area that is part of 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 home, and multiple dwelling units or homes. A "second residential area" is a residential area that is part of 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."

The term "output means" refers to means for outputting display warning 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. Specifically, it refers to 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. For example, this concept includes means for causing the first alarm device to emit light and output display warning information. It also refers to means for outputting abnormality occurrence information from a second alarm device in a manner different from the display warning information output via the first alarm device, and means for outputting display warning information from the warning output means of the first alarm device. "Abnormality occurrence information" will be described later.

"Display alarm information" refers to information related to an abnormality, specifically information output to the outside or inside of the residential area. For example, this information is 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 perceptible information, and examples of this include information displayed in the form of light, images, text, etc. "Display alarm information" refers to information for notifying users that an abnormality has occurred. "Abnormality occurrence information" refers to information related to an abnormality, specifically information output to the outside or inside of the residential area. For example, this information is output via a second alarm device, which is an alarm device other than the first alarm device. It is also visually perceptible information, and examples of this include information displayed in the form of light, images, text, etc. "Abnormality occurrence information" refers to information identifying that the determination means has determined that an abnormality has occurred in the first residential area. The display alarm information and abnormality occurrence information may be output by the output means in the same manner or in different ways. Note that "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 outputting this information 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 (e.g., light emission) may be output in different modes (e.g., with different light emission timing, blinking speed, or light emission intensity).

The term "first alarm device" refers to a device that issues an alarm for at least the first residential area among multiple residential areas. Specifically, it refers to a device that issues an alarm at least to the outside or inside of the first residential area. It also refers to a device in which at least a portion of the alarm output means of the first alarm device is located outside or inside the first residential area. For example, it is a concept that includes devices that issue at least a visible alarm, such as devices that emit light, output images, and output text. The term "first alarm device" refers to a device associated with the first residential area, and also refers to a device that is located at a position corresponding to the position of the first residential area (for example, the outer surface of a wall or door of the first residential area). The term "alarm output means" refers to part of the first alarm device, and includes, for example, some components for outputting information (note that the alarm output means of the second alarm device, described below, also has a similar concept).

Furthermore, "other devices" refers to devices that are different from the first alarm device, and specifically refers to a concept that includes devices of the same type and devices of different types, such as a second alarm device, a lock device, and a recording device.

Furthermore, a "second alarm device" is a device that issues an alarm for at least a second living area among multiple 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 located outside or inside the second living area. This concept includes, for example, devices of the same type as the first alarm device that issue at least a visible alarm, and examples include devices that emit light, output images, and output text. Furthermore, a "second alarm device" is, for example, a device associated with the second living area, and a device that is located in 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).

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 implemented 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 implemented using technology such as so-called smart speakers. The term "information about the resident of the first living area" refers to, 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.

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.

Furthermore, "disaster prevention processing" refers to processing related to disaster prevention in the first residential area. Specifically, it is processing carried out in coordination with other measures, and is a concept that includes, for example, the first to fourth disaster prevention processing. "First disaster prevention processing" refers to processing carried out in coordination 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. "Second disaster prevention processing" refers to processing carried out in coordination 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. "Third disaster prevention processing" refers to processing carried out in coordination 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. The "fourth disaster prevention process" is a process carried out in cooperation with a recording device, and includes, for example, a process of referencing information recorded in the recording device to estimate the current state of the occupant and issuing an alert according to the estimated state of the occupant.

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

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

(composition)
First, the configuration of the disaster prevention system according to this embodiment will be described. Fig. 1 is a diagram showing a residential 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 the installation of an indicator light device. In reality, there are four or more residential areas 8, but Fig. 1 illustrates and explains three representative residential areas 81 to 83. These residential areas 81 to 83 will be collectively referred to as "residential area 8" (the same applies to the detector 1, indicator light device 2, and door 7) except when they are to be described separately from one another.

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

(Configuration-sensor)
Detector 1 is an abnormality detection means for detecting a fire occurring in the 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 (e.g., indicator light device 2). Detector 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 detector 1 are arbitrary, but for example, detector 1 may be installed in 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, etc.

(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.

(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 the communication unit 21 are arbitrary, but it can be configured using, for example, a known wireless communication circuit or the like.

(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 may be 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 the display unit 22 may be configured so that only a portion of it is provided outside the living area 8.

(Configuration - Indicator Light Device - Recording Unit)
The recording unit 23 is a recording means for recording programs and various data required 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 may 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 a 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.

(Configuration—Indicator Light Device—Recording Unit—Indicator Light Device ID)
The "indicator light device ID" is device identification information (identification information will also be referred to as "ID") that uniquely identifies the indicator light device 2. The specific recording method for such an indicator light device ID is arbitrary, but for example, it is assumed that it is recorded by input 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.

(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 condominium), or the floor number or plan coordinates that indicate the location of components (e.g., door 7, etc.) set in each residential area.

(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. FIG. 4 is a diagram illustrating residential area related information. As shown in FIG. 4, the residential area related information stores, for example, the items "residential area ID,""sensorID,""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" is the residential area ID of residential area 81 in FIG. 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 (e.g., 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). The information corresponding to the item "indicator light device ID" is, as described above, a indicator light device ID that uniquely identifies the indicator light device 2 installed in each residential area 8 (e.g., 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). The information corresponding to the item "location information" is location information that identifies the location of the residential area 8. This location information is stored as information that enables the relative positional relationships between the residential areas 8 (e.g., the distance between the residential areas 8) to be identified 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."

(Configuration—Indicator Light Device—Recording Unit—Operating Condition Information)
The "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.

The information corresponding to the "Status Information" item is status information that specifies the status of the signal light device 2 related to coordination. This status information specifies whether the signal light device 2 is operating as a coordination source device or a coordination destination device, and, if it 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.

Note that 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 refers to the indicator light device 2 installed in the living area 8 where a fire has been detected. Note that 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 refers to the indicator light device 2 installed in the living area 8 where no fire has been detected.

In Figure 5, "Initial Link," "Destination 1," "Destination 2," "Destination 3," and "Destination 4" are recorded. Note that "Initial Link" indicates a state in which the device is operating as an initial link, while "Destination 1," "Destination 2," "Destination 3," and "Destination 4" indicate a state in which the device is operating as a destination link. In particular, the numbers "1," "2," "3," and "4" in "Destination 1," "Destination 2," "Destination 3," and "Destination 4" indicate a location relative to the initial link. "1" to "3" indicate a location on the same floor as the initial link, with larger numbers indicating greater distances, and "4" indicating a location that is not on the same floor as the initial link. Regarding "1" to "3" in more detail, "1" indicates that the installation location of the coordination target device corresponds to the residential area 8 that is one area next (i.e., adjacent) to the residential area 8 in which the coordination source device is installed, "2" indicates that the installation location of the coordination target device corresponds to the residential area 8 that is two areas away from the residential area 8 in which the coordination source device is installed, and "3" indicates that the installation location of the coordination target device corresponds to the residential area 8 that is three or more areas away from the residential area 8 in which the coordination source device is installed.

The information corresponding to the "Light Emission Mode Information" item is light emission mode information that specifies the light emission mode of the display unit 22. This light emission mode information can be any information; for example, in Figure 4, the light emission mode is specified as the light intensity and blinking rate (the time interval between blinks). 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 blinking rate are each set to five levels, and an example will be described in Figure 5 where "Intensity: 5, Speed: 5" is recorded. Note that "Intensity: 5, Speed: 5" specifies that the light intensity corresponds to "5" and the blinking rate corresponds to "5." Furthermore, for the light intensity and blinking rate values shown in Figure 5, the higher the value, the stronger the intensity and the faster the blinking rate. The specific values for these intensities and flashing speeds can be arbitrary, but for example, "Intensity: 5, Speed: 5" indicates that the light will flash at approximately "7000 to 8000 lumens" at intervals of approximately "0.5 to 1 second," while "Intensity: 4, Speed: 4" indicates that the light will flash at approximately "6000 to 6500 lumens" at intervals of approximately "2 to 3 seconds."

(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 run on the OS and implement specific functions), and an internal memory such as a RAM for storing programs and various data. In particular, the program according to the embodiment is installed in the signal light device 2 via an arbitrary recording medium or a network, thereby substantially configuring each part of the control unit 24.

The control unit 24 conceptually comprises a determination unit 241 and an output unit 242. The determination unit 241 is a determination means for determining whether an abnormality has occurred in a first 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 for at least the first living area, when the determination unit 241 determines that an abnormality has occurred in the first living area. Specifically, the output unit 242 is a means for 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 warning device. The processing performed by each unit of the control unit 24 will be described below.

(process)
Next, we will explain the coordination source side disaster prevention processing and coordination destination side disaster prevention processing executed by the disaster prevention system 900 configured as described above. Here, for example, each of the signal light devices 2 in Figure 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. In particular, we will 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.

(Processing - Disaster prevention processing on the cooperation source side)
First, the disaster prevention process on the coordination source side will be described. Figure 6 is a flowchart of the disaster prevention process on the coordination source side (steps will be abbreviated as "S" in the following description of each process). 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 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 in the disaster prevention system 900 is powered on, it is started up and begins execution, and the description will begin from the point at which execution begins (the same applies to the disaster prevention process on the coordination destination side).

In SA1 of FIG. 6, the determination unit 241 determines whether 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 is made based on whether this alarm signal has been received by monitoring the communication unit 21. 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 occurs in the living 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.

At SA2 in FIG. 6, the output unit 242 determines the light emission mode. Specific details are arbitrary, but for example, if the device itself has determined that a fire has occurred and is operating as a coordination source device, the output unit 242 references 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 references the operating condition information in FIG. 5 to acquire light emission mode information whose status information is "coordination source," such as "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."

At SA3 in FIG. 6, the output unit 242 starts emitting light, thereby starting the output of the display warning information. While specific details are arbitrary, for example, the light emission mode determined at SA2 is identified, 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 indicator light device 201 identifies the light emission mode corresponding to the light emission mode determined at SA2, "intensity: 5, speed: 5," 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 indicator light device 201 starts flashing so as to repeatedly output light of approximately "7000 to 8000 lumens" at intervals of approximately "0.5 to 1 second."

At 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 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.

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.

At SA5 in FIG. 6, the determination unit 241 determines whether recovery has occurred. While specific details are optional, for example, when a predetermined operation (an action to restore) is performed on a disaster prevention receiver (not shown), the disaster prevention receiver outputs a restoration signal, and the determination is made by monitoring the communication unit 21 based on whether this restoration signal is received. If a restoration signal is not received, it is determined that restoration has not occurred (NO in SA5), and SA5 is repeatedly executed until it is determined that restoration has occurred. Furthermore, if a restoration signal is received, it is determined that restoration 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 restoration signal, and the determination unit 241 of the indicator light device 201 receives the restoration signal and determines that restoration has occurred.

At SA6 in FIG. 6, the output unit 242 stops outputting the display warning information by ending light emission. While specific details are arbitrary, for example, light emission is ended 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 approximately 7,000 to 8,000 lumens at intervals of approximately 0.5 to 1 second on the display unit 22 of the indicator light device 201.

In SA7 of Figure 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 coordination source device. The specifics of SA7 are arbitrary, but for example, it is similar to SA4, in that it obtains the indicator light device ID recorded in its own recording unit 23, adds the obtained indicator light device ID as the indicator light device ID of the coordination 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.

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, generates a recovery relay signal, and transmits the generated recovery relay signal. This recovery relay signal then reaches, for example, the nearby indicator light device 2, indicator light device 202. This completes the coordination source side disaster prevention processing.

(Processing - Disaster prevention processing on the 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.

At SB1 in 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 obtain the indicator light device ID of the coordination source device contained in the alarm relay signal received by the communication unit 21, and also obtain the indicator light device ID of its own recording unit 23, and then determine whether these obtained 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 2 as a coordination source device relayed by another indicator light device 2, and determines that an alarm relay signal has not been received (NO in SB1), and repeatedly executes SB1 until it determines that an 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 an 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 signal including "ID201," since its own indicator light device ID is "ID202," the acquired "ID201" does not match "ID202," which is the indicator light device ID of its own recording unit, and it determines that an alarm relay signal has been received.

At SB2 in FIG. 7, the control unit 24 determines the light emission mode. While the specifics are 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), it will operate as a coordination destination device. Specifically, the control unit 24 references the operating condition information in FIG. 5 to acquire the status information "Coordination destination 1" to "Coordination destination 4." Next, the control unit 24 references the residential area-related information in FIG. 4 to acquire location information corresponding to the indicator light device ID of the coordination source device included in the alarm relay signal acquired at SB1 and location information corresponding to its own indicator light device ID. Next, the control unit 24 references the map information in the recording unit 23 in FIG. 2 to determine 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., location 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 "Linked Destination 1" to "Linked Destination 4," and light emission mode information corresponding to the selected piece of status information is acquired from the operating condition information in Figure 5. 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.

Here, for example, the control unit 24 of the signal light device 202 references the operating condition information in Figure 5 to acquire the status information "Linkage Destination 1" to "Linkage Destination 4." Next, by reference to the residential area-related information in Figure 4, it acquires "Room 101" as the location information corresponding to "ID201," which is the signal light device ID of the communication source device included in the alarm relay signal acquired in SB1, and "Room 102" as the location information corresponding to "ID202," which is its own signal light device ID. Next, it references the map information in the recording unit 23 in Figure 2 to determine the relative positional relationship between the residential area 81 corresponding to "Room 101," which is the location information of the communication 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 communication destination device). Next, since the installation location of the coordination destination device corresponds to the residential area 82 adjacent to the residential area 81 in which the coordination source device is installed, "Coordination destination 1" is selected from the previously acquired "Coordination destination 1" to "Coordination destination 4," and in the operating condition information in FIG. 5, "intensity: 4, speed: 4" is acquired as the light emission mode information corresponding to the selected "Coordination destination 1." It is then 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."

At SB3 in FIG. 7, the control unit 24 starts emitting light, thereby starting to output abnormality occurrence information. While specific details are arbitrary, for example, the control unit 24 identifies the light emission mode determined at SB2 and starts emitting light in the determined light emission mode on the display unit 22 in FIG. 3. Here, for example, the control unit 24 of the indicator light device 202 identifies the light emission mode corresponding to the light emission mode determined at SB2, "intensity: 4, speed: 4," and starts emitting light in the determined light emission mode corresponding to "intensity: 4, speed: 4," on the display unit 22 in FIG. 3. In this case, the display unit 22 of the indicator light device 202 starts flashing so as to repeatedly output light of approximately "6000 to 6500 lumens" at intervals of approximately "2 to 3 seconds."

At SB4 in FIG. 7, the control unit 24 cooperates with other indicator light devices 2 by transmitting and relaying an alarm relay signal. While specific details are optional, for example, the control unit 24 may transmit and relay the alarm relay signal received at 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, indicator light device 203, which is a nearby indicator light device 2.

At SB5 in FIG. 7, the control unit 24 determines whether it has received a return relay signal transmitted by another indicator light device 2 acting as the coordination source device. While specific details are optional, for example, the control unit 24 may monitor the communication unit 21 to obtain the indicator light device ID of the coordination source device contained in the return relay signal received by the communication unit 21, and also obtain the indicator light device ID of the coordination source device contained in the alarm relay signal obtained at SB1, and then determine whether these obtained 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 at SB1, and determines that a return relay signal has not been received (NO at SB5), and repeatedly executes SB5 until it determines that a 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 at SB1, and determines that a return relay signal has been received (YES at 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 at SB1 also contains "ID201," the control unit 24 determines that these match and that a return relay signal has been received.

At SB6 in Figure 7, the control unit 24 cooperates with other indicator light devices 2 by transmitting and relaying a return relay signal. Specific details are arbitrary, but for example, the control unit 24 may transmit and relay 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, indicator light device 203, which is a nearby indicator light device 2.

At SB7 in Figure 7, the control unit 24 ends the output of the abnormality occurrence information by ending light emission. Specifically, the light emission can be ended by turning off the display unit 22 in Figure 3, for example. Here, for example, the control unit 24 of the indicator light device 202 ends the flashing of a light of approximately 6000 to 6500 lumens at intervals of approximately 2 to 3 seconds on the display unit 22 of the indicator light device 202. This ends the disaster prevention processing on the partner side.

(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 fire and outputs an alarm signal. In response to YES at SA1 in Fig. 6 , in SA2, the indicator light device 201 determines the light emission mode corresponding to "intensity: 5, speed: 5" in Fig. 5 , and then in SA3, starts emitting light in the determined mode and transmits an alarm relay signal to SA4.

Meanwhile, the indicator light device 202 receives the alarm signal, and at SB2 after YES at SB1 in Figure 7, determines the light emission mode corresponding to "Intensity: 4, Speed: 4", then at SB3, begins emitting light in the determined mode and relays the alarm relay signal to SB4. Meanwhile, the indicator light device 203 receives the alarm signal, and at SB2 after YES at SB1 in Figure 7, determines the light emission mode corresponding to "Intensity: 3, Speed: 3", then at SB3, begins emitting light in the determined mode and relays the alarm relay signal to SB4.

By visually checking the light emitted by the display unit 22 of each indicator light device 2, users outside the residential area 8 (for example, residents or firefighters) 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 then take the necessary measures.

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

(Effects of the embodiment)
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.

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 an abnormality, such as a fire. This makes it possible to notify residents living near the first living area where a fire has been detected of the abnormality, enabling them to quickly take the necessary disaster prevention measures (e.g., fire extinguishing, rescue, etc.).

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 widely notify an abnormality in the first residential area. Furthermore, for example, because the information formats of the first alarm device and the second alarm device are different, it is possible to notify whether an abnormality has actually occurred in a residential area, and it is possible to quickly take the necessary disaster prevention measures (for example, fire extinguishing, rescue, etc.).

Furthermore, by outputting display alarm information from the second alarm device in a different light emission mode from the first alarm device, it is possible, for example, to output information regarding an abnormality by light emission not only from the first alarm device but also from the second alarm device, making it possible to widely notify people of an abnormality in the first residential area. Furthermore, for example, because the light emission modes of the information from the first alarm device and the second alarm device are different, it is possible to notify people whether an abnormality has actually occurred in the residential area, and 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.

Furthermore, by illuminating the first alarm device and outputting the displayed 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.

Furthermore, because 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, enabling people in the vicinity of the residential area 8 to quickly take the necessary disaster prevention measures (for example, firefighting, rescue, etc.).

[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.

(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.

(Regarding decentralization and integration)
Furthermore, the above-described configuration is merely a functional concept and does not necessarily have to be physically configured as shown. In other words, the specific form of distribution or integration of each component is not limited to that shown, and all or part of the components 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 configuration consisting 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.

(About information output (part 1))
In the above embodiment, different information is output by varying the light intensity and blinking rate based on the operating condition information of FIG. 5 . However, this is not limiting. For example, by utilizing the fact that each of the signal light devices 2 is configured to be able to communicate with each other, each of the signal light devices 2 may sequentially blink the display unit 22 of each device so that the user gets 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 of the signal light devices 2. Alternatively, the direction of the light flow impression may be reversed to provide evacuation guidance.

(About information output (part 2))
Alternatively, different information may be output by, for example, varying the color or blinking pattern of the output light. 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, and text information or image information may be displayed via these display means. In this configuration, for example, information identifying the location of the living area 8 where the fire occurred (e.g., the floor number and name (e.g., Room 101)) may be displayed as text information or image information.

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 occupants (residents) of the dwelling unit in which the indicator light device 2 is installed (for example, the age of the resident, the number of resident(s), 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 hazardous materials, etc. (hazardous material presence/absence information) can be displayed.

Furthermore, for example, if different information is output by varying the color of light, one example would be to use an LED capable of emitting both red and green light, and have only the indicator light device 2 installed in the fire alert dwelling unit (the residential area where a fire has been determined) emit red light, and have the indicator light devices 2 installed in neighboring dwelling units emit green light.

Furthermore, when different information is output by, for example, using different flashing patterns, for example, the light emission cycle may be the same, and the duty ratio (the ratio of the light emission time to the light emission cycle) of the indicator light devices 2 installed in each dwelling unit may be varied to output different information (for example, by decreasing the duty ratio as the distance from the dwelling unit where the fire alarm was issued increases).

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 be configured to transmit a predetermined signal (a signal of a predetermined intensity) other than an alarm relay signal, and the target device may be configured to 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 in accordance with the measured received radio wave intensity. In particular, information specifying the relationship between received radio wave intensity and light emission intensity (for example, 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 be configured to control its own light emission intensity by referencing the recorded information.

(Regarding the second disaster prevention measures)
The indicator light device 2 of the above embodiment may also 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 of 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. 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 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, if evacuation is necessary, evacuation to a safe direction (e.g., a direction that avoids the source of the fire) can be promptly carried out.

(Interpretation of the second disaster prevention measure)
In the embodiment, as shown in Figure 5, when it is noted that the light intensity of linked 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 multiple linked 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.

(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, 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 locking device may be controlled to unlock the door 7 of the living area 8 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 an access control device may be provided in the living area 8 to confirm that no users are 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 in 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 the door or prohibit entry by locking the door, thereby improving disaster prevention capabilities. Furthermore, for example, crime prevention in the event of an abnormality can be improved.

(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," and "Good night, turn off the lights"), as well as 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 system may determine the resident's average wake-up time and average bedtime based on phrases such as "good morning" and "good night" and the time at which they are spoken. When SA3 of FIG. 6 or SB3 of FIG. 7 is executed, the system may obtain the current time from its own timing means (e.g., a timer) and compare the obtained current time 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. Specifically, 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 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.

(Regarding indicator light devices)
Furthermore, 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.

(Regarding restoration judgment)
In addition, in SA4 of Figure 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 a 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.

(Regarding abnormalities and determination means)
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.

(Regarding 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.

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

(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 living 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, thereby enabling disaster prevention to be carried out from multiple angles and improving disaster prevention capabilities.

The disaster prevention system described in Appendix 2 outputs abnormality occurrence information via a second alarm device that issues an alarm for at least the second residential area, making it possible to, for example, notify the second residential area of the occurrence of an abnormality. Therefore, for example, neighboring residents of the first residential area where the abnormality was detected can also be notified of the occurrence of the abnormality, enabling them to quickly take the necessary disaster prevention measures (for example, firefighting, rescue, etc.).

According to the disaster prevention system described in Appendix 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. Therefore, for example, neighboring residents of the first residential area where the abnormality was detected can also be notified of the source of the abnormality, enabling them to quickly take the necessary disaster prevention measures (e.g., firefighting, rescue, etc.). In particular, because it is possible to identify the source of the abnormality, if evacuation is necessary, evacuation can be quickly carried out in a safe direction (e.g., a direction that avoids the source of the abnormality).

According to the disaster prevention system described in Appendix 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, for example, 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 residential area. Furthermore, for example, because the information manner differs between the first alarm device and the second alarm device, it is possible to notify whether an abnormality has actually occurred in the residential area, making it possible to quickly take the necessary disaster prevention measures (for example, fire extinguishing, rescue, etc.).

According to the disaster prevention system described in Appendix 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, because 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 has actually occurred in an residential area, and 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.

The disaster prevention system described in Appendix 6 allows the locking device to lock or unlock the first living area, thereby improving disaster prevention capabilities, for example, by unlocking the area to facilitate evacuation or locking the area to prohibit entry. It also makes it possible to improve crime prevention in the event of an emergency, for example.

The disaster prevention system described in Appendix 7 references information recorded in a recording device to estimate the current condition of the resident and issues an alarm according to the estimated condition of the resident, making it possible, for example, to carry out rescue operations appropriately according to the resident's condition. In particular, it becomes possible to determine, for example, whether a resident is in a condition requiring prompt rescue and to carry out rescue operations as a priority.

The disaster prevention system described in Appendix 8 enables the first alarm device to emit light and output display alarm information, thereby ensuring a reliable alarm, even at night, for example, thereby improving disaster prevention capabilities. Furthermore, even if an abnormality occurs, causing chaos and confusion in the surrounding area, the alarm can be reliably recognized visually.

In the disaster prevention system described in Appendix 9, at least a portion of the alarm output means of the first alarm device is provided outside the first living area, which makes it possible to reliably notify people outside the first living area of the occurrence of an abnormality, thereby enabling people in the vicinity of the first living area to quickly take the necessary disaster prevention measures (e.g., firefighting, rescue, etc.).

In the disaster prevention system described in Appendix 10, since the abnormality is a fire, it is possible to perform fire prevention processing from all angles, rather than just processing a single alarm from the first alarm device, thereby enabling fire prevention to be carried out from multiple angles and improving disaster prevention capabilities.
