  On the other hand, as one of the types of fires, when a cigarette is used for smoking, the type of cigarette falls on the user's bedding and the bedding burns, and the fire is caused by the cause. In the initial stage, the flame hardly rises, but a fire in which the concentration of toxic gas (for example, smoke, carbon monoxide, carbon dioxide, or hydrogen cyanide, etc.) locally increases around the fire source (hereinafter referred to as smoldering) Fire). When such a “smoldering fire” occurs, in the initial stage of the fire occurrence, the concentration of the toxic gas locally increases around the fire source (for example, near the mouth of a sleeping user), and the toxic gas increases. There is a possibility that the user who smokes may be in a dangerous state such as poisoning with poisonous gas.

  However, general fire alarms, including the fire alarm of Patent Literature 1, are provided at a position away from the sleeping user, such as near the ceiling or the upper end of the wall, so that "smoke fire" It takes a relatively long time before the concentration of the detection target around the fire alarm rises after the occurrence of the fire alarm, so that the detection of the fire is delayed, and the sleeping user inhales toxic gas.

(Configuration-Sensor)
The sensor 5 is a detection target detection unit that detects a physical quantity of a detection target in the monitoring area, and particularly detects a CO gas concentration in the monitoring area. The specific configuration of the sensor 5 is arbitrary, and for example, a known sensor such as an electrochemical gas sensor can be used.

(Configuration-recording unit)
The recording unit 6 is a recording unit that records programs and various data necessary for the operation of the disaster prevention terminal 100, and is configured using, for example, a hard disk (not shown) as an external recording device. However, in place of or in addition to the hard disk, a magnetic recording medium such as a magnetic disk, an optical recording medium such as a DVD or a Blu-ray disk, or an electric recording medium such as a Flash, a ROM, a USB memory, or an SD card. Any recording medium can be used.

  The recording unit 6 stores sensitivity specifying information. The “sensitivity specifying information” is information for specifying “sensitivity for detecting an abnormality” in the disaster prevention terminal 100. As the “sensitivity specifying information”, any information can be used according to a method of detecting an abnormality in the disaster prevention terminal 100. For example, here, for example, “a method of detecting an abnormality in the disaster prevention terminal 100” Is a method of comparing the detection result of the sensor 5 with a fire determination threshold value described later. FIG. 3 is a diagram illustrating sensitivity specifying information. As shown in FIG. 3, the sensitivity specifying information is configured by associating the item “sleep information”, the item “sensitivity information”, the item “fire determination threshold information”, and the information corresponding to each item with each other. ing. Here, the information corresponding to the item “sleep information” is sleep information that specifies whether or not a person is sleeping and the depth of sleep (in FIG. 3, the user is awake (that is, not sleeping). ), “Sleeping (light)” indicating sleeping and light sleep, and “sleeping (deep)” indicating sleeping and deep sleep). The information corresponding to the item “sensitivity information” is sensitivity information that specifies the level of sensitivity for detecting abnormality (in FIG. 3, the sensitivity is lower than “low” or “low” indicating low sensitivity).

  The control unit 7 includes a sleep determination unit 71 and an abnormality detection unit 72 in a functional concept. The sleep determination unit 71 is a sleep determination unit that determines a user's sleep. Further, the abnormality detection unit 72 is an abnormality detection unit for detecting an abnormality in the monitoring area based on the detection result of the sensor 5, and is particularly a fire detection unit for detecting a fire in the monitoring area. The processing performed by each unit of the control unit 7 will be described later.

(processing)
Next, a disaster prevention process executed by the disaster prevention terminal 100 configured as described above will be described. FIG. 4 is a flowchart of the disaster prevention process (steps are abbreviated as “S” in the following description of each process). “Disaster prevention processing” is processing relating to disaster prevention, and specifically, processing for detecting a fire in the monitoring area. The timing of executing this disaster prevention process is arbitrary timing. For example, in a state where the power of the disaster prevention terminal 100 is turned on, it is assumed that the disaster prevention terminal 100 is activated and executed after the user performs an activation operation via the touch pad 2. The description starts from the point where the disaster prevention process is started. Further, as shown in FIG. 1, the disaster prevention terminal 100 is placed on the bed (specifically, at a position where the movement of a person lying on the bed is transmitted, and the disaster prevention terminal is described in SA1 and SA2 in FIG. 4 described later). The following description will be made on the assumption that the movement of a person is transmitted to the terminal 100 and the terminal is located at an arbitrary position where sleep can be appropriately determined, for example, at a bedside.

  First, as shown in FIG. 4, in SA1, the sleep determination unit 71 determines whether or not the user is sleeping. As a method of determining whether or not the user is sleeping, any method including a known method can be used. Here, for example, an acceleration detection unit (such as an acceleration sensor) for the disaster prevention terminal 100 in FIG. (Not shown), and a method of making a determination based on the detection result of the acceleration detecting means will be described below. Specifically, regarding the movement of the person transmitted to the acceleration detection unit of the disaster prevention terminal 100 via a bed or a futon, the movement when sleeping is the case where the person is awake (that is, not sleeping). Focusing on the fact that the movement is smaller than the movement of (case) and that the movement of the person becomes smaller as the sleep becomes deeper, it is determined whether or not the user is sleeping based on the detection result of the acceleration detecting means. . As for a specific method of “determining whether or not the user is sleeping based on the detection result of the acceleration detection unit”, a known method (for example, comparing the detection result of the acceleration detection unit with a reference value) , Etc.) can be used, and a detailed description thereof will be omitted. When it is determined that the user is sleeping (YES in SA1), the process proceeds to SA2. When it is determined that the user is not sleeping (NO in SA1), the process proceeds to SA6.

  Returning to FIG. 4, in SA2, the sleep determination unit 71 determines whether the user's sleep is deep (non-REM sleep or REM sleep) as a determination of the user's sleep state (specifically, sleep depth). Is determined. As a method of determining the sleep state of the user, any method including a known method can be used. Here, for example, in the same manner as in the case of SA1, not shown of the disaster prevention terminal 100 in FIG. A description will be given below assuming that a determination method is used based on the detection result of the acceleration detection means. Specifically, regarding the movement of the person transmitted to the acceleration detection unit of the disaster prevention terminal 100 via a bed or a futon, the movement when sleeping is the case where the person is awake (that is, not sleeping). Focusing on the fact that the movement of the user is smaller than the movement of (case) and that the movement of the person becomes smaller as the sleep becomes deeper, it is determined whether or not the user's sleep is deep based on the detection result of the acceleration detecting means. . As for a specific method of “determining whether or not the user has a deep sleep based on the detection result of the acceleration detection unit”, a known method (for example, comparing the detection result of the acceleration detection unit with a reference value) , Etc.) can be used, and a detailed description thereof will be omitted. When it is determined that the user sleeps deeply (YES in SA2), the process proceeds to SA3. If it is determined that the user's sleep is not deep (that is, if the user's sleep is determined to be light) (NO in SA2), the process proceeds to SA7.

  Returning to FIG. 4, in SA3, the abnormality detection unit 72 sets the sensitivity. Specifically, referring to the sensitivity specifying information in FIG. 3, “fire determination threshold information” corresponding to the determination results of SA1 and SA2 in FIG. 4 is acquired, and the acquired “fire determination threshold information” specifies. The "fire determination threshold value" is recorded and set in the recording unit 6 of FIG. More specifically, since “the determination result of SA1” = “the user is sleeping” and “the determination result of SA2” = “the user is deeply sleeping”, “sleep information” = “sleep ( “Fire determination threshold information” = “20” corresponding to “deep)”, and “Fire determination threshold information” = “20 (ppm)” specified by the acquired “fire determination threshold information” = “20” in FIG. (That is, the sensitivity is maximized).

  Returning to FIG. 4, in SA4, the abnormality detection unit 72 determines whether a fire has occurred (that is, detects a fire). Specifically, the detection results (that is, the concentration of CO gas) of the sensor 5 in FIG. 2 are obtained, and the fire determination threshold value set immediately near the recording unit 6 is obtained. Is compared with the acquired fire determination threshold value, and whether or not a fire has occurred is determined based on the comparison result. If the acquired detection result exceeds the acquired fire determination threshold, it is determined that a fire has occurred (YES in SA4), and the process proceeds to SA5. If the acquired detection result does not exceed the acquired fire determination threshold, it is determined that a fire has not occurred (NO in SA4), and the process proceeds to SA1. Here, for example, a case where “the detection result of the sensor 5 in FIG. 2” = “25 (ppm)” will be described as an example. In this case, the “detection result of the sensor 5” = “25 (ppm)” is acquired, and the “fire determination threshold value set nearest to the recording unit 6” = “20 (ppm)”. Is compared with the acquired fire determination threshold value, the “detection result of the sensor 5” = “25 (ppm)” is changed to “the fire determination threshold value set closest to the recording unit 6” = “20 (ppm) )], It is determined that a fire has occurred.

  Returning to FIG. 4, in SA5, the control unit 7 issues a warning about the occurrence of a fire, and ends the processing. The warning mode, which is a mode for performing a warning, is arbitrary as long as it is a mode that can ensure the safety of the user. Here, for example, using the communication unit 1, the display 3, and the speaker 4 of FIG. The following alarms shall be issued. Specifically, the communication unit 1 transmits, to the disaster prevention center, a transfer signal that is a signal for notifying that a fire has occurred. In addition, an image indicating that a fire has occurred or text information such as "a fire has occurred" is displayed via the display 3. In addition, voice information such as “a fire has occurred” is output via the speaker 4.

  In SA6 after it is determined that the user is not sleeping in SA1 of FIG. 4 (NO in SA1), the abnormality detection unit 72 sets the sensitivity. Specifically, “fire determination threshold information” corresponding to the determination result of SA1 in FIG. 4 is acquired with reference to the sensitivity identification information in FIG. 3, and “fire determination threshold information” specified by the acquired “fire determination threshold information” is obtained. The “threshold value” is recorded in the recording unit 6 of FIG. 2 and set. More specifically, since “SA1 determination result” = “the user is not sleeping”, “fire determination threshold information” = “60” corresponding to “sleep information” = “awake” in FIG. 3 is obtained. Then, the obtained “fire judgment threshold information” = “60” and “fire judgment threshold” = “60 (ppm)” are recorded in the recording unit 6 of FIG. 2 and set (that is, the sensitivity is reduced to the minimum). Let it do).

  At SA4 in FIG. 4 thereafter, the abnormality detection unit 72 determines whether or not a fire has occurred (that is, detects a fire), as described above. Here, for example, a case where “the detection result of the sensor 5 in FIG. 2” = “25 (ppm)” will be described as an example. In this case, the “detection result of the sensor 5” = “25 (ppm)” is obtained, and the “fire determination threshold value set nearest to the recording unit 6” = “60 (ppm)”. Is compared with the acquired fire determination threshold value, the “detection result of the sensor 5” = “25 (ppm)” is changed to “the fire determination threshold value set closest to the recording unit 6” = “60 (ppm) ) ”, It is determined that no fire has occurred.

  Further, in SA7 after it is determined in SA2 of FIG. 4 that the user does not sleep deeply (NO in SA2), the abnormality detection unit 72 sets the sensitivity. Specifically, referring to the sensitivity specifying information in FIG. 3, “fire determination threshold information” corresponding to the determination results of SA1 and SA2 in FIG. 4 is acquired, and the acquired “fire determination threshold information” specifies. The "fire determination threshold value" is recorded and set in the recording unit 6 of FIG. More specifically, since “the determination result of SA1” = “the user is sleeping” and “the determination result of SA2” = “the user's sleep is not deep”, “sleep information” in FIG. “Fire determination threshold information” = “40” corresponding to “(shallow)” and “Fire determination threshold” = “40 (ppm)” specified by the acquired “fire determination threshold information” = “40” 2 is recorded in the recording unit 6 and set.

  At SA4 in FIG. 4 thereafter, the abnormality detection unit 72 determines whether or not a fire has occurred (that is, detects a fire), as described above. Here, for example, a case where “the detection result of the sensor 5 in FIG. 2” = “25 (ppm)” will be described as an example. In this case, the “detection result of the sensor 5” = “25 (ppm)” is acquired, and the “fire determination threshold value set nearest to the recording unit 6” = “40 (ppm)”. Is compared with the acquired fire determination threshold value, the “detection result of the sensor 5” = “25 (ppm)” is changed to “the fire determination threshold value set closest to the recording unit 6” = “40 (ppm) ) ”, It is determined that no fire has occurred. This ends the disaster prevention processing.

(Effects of Embodiment)
As described above, according to the present embodiment, by changing the state for detecting abnormality in the monitoring area based on the determination result of the sleep determining unit 71, for example, the monitoring area may be considered in consideration of the user's sleep. Since the state for detecting the abnormality can be changed, the abnormality in the monitoring area can be quickly and reliably detected in consideration of the user's sleep. In particular, for example, when the user is sleeping, by changing the state for detecting an abnormality in the monitoring area so as to quickly detect a fire that is an abnormality in the monitoring area, the aforementioned “smoking fire” Can be detected immediately after the occurrence of "", and it is possible to prevent a sleeping user from inhaling toxic gas and causing toxic gas poisoning or the like.

  Also, once it is determined that the user is not sleeping, if the user is determined to be sleeping, by changing the sensitivity of detecting an abnormality in the monitoring area, for example, the abnormality in the monitoring area is detected. When the user is sleeping, the abnormality in the monitoring area can be quickly detected, and thus the safety of the user during sleep can be reliably ensured.

  Further, by giving a warning about the abnormality, for example, it is possible to warn the user or the like of the abnormality in the monitoring area, so that the safety of the user can be more reliably ensured.

  Further, since the abnormality in the monitoring area is at least an abnormality relating to disaster prevention, for example, an abnormality relating to a disaster such as the occurrence of a fire can be detected quickly and reliably, so that safety in the monitoring area can be improved.

[Modification to Embodiment]
As described above, the embodiment according to the present invention has been described. However, the specific configuration and means of the present invention may be arbitrarily modified and improved within the technical idea of each invention described in the claims. Can be. Hereinafter, such modified examples will be described.

(About problems to be solved and effects of the invention)
First, the problems to be solved by the invention and the effects of the invention are not limited to the contents described above, and may differ depending on the implementation environment and details of the configuration of the invention. May be solved, or only a part of the effects described above may be achieved.

(About distribution and integration)
Further, the above-described configuration is conceptual in function, and does not necessarily need to be physically configured as illustrated. That is, the specific form of distribution and integration of each unit is not limited to the illustrated one, and all or a part thereof can be functionally or physically distributed or integrated in arbitrary units. The “system” in the present application is not limited to a system configured by a plurality of devices, but includes a system configured by a single device. The “device” in the present application is not limited to a device configured by a single device, but includes a device configured by a plurality of devices.

(About alarm (1))
Further, in the above-described embodiment, the case where the alarm is performed using the communication unit 1, the display 3, and the speaker 4 in FIG. 2 in SA5 in FIG. 4 has been described, but the present invention is not limited thereto. For example, the disaster prevention terminal 100 shown in FIG. 2 may be provided with a vibration function, and an alarm may be issued using vibration by the vibration function.

(About the alarm (part 2))
Further, at SA5 in FIG. 4, the disaster prevention terminal 100 in FIG. 2 may issue an alarm in conjunction with another device. Specifically, the monitoring area is a plurality of rooms in a house, and each of the plurality of rooms is provided with a known fire alarm for a house that operates in conjunction with each other. In conjunction with the residential fire alarm, a warning may be issued to a room where the disaster prevention terminal 100 is provided or a room where the disaster prevention terminal 100 is not provided. In addition, it is assumed that a notification device which is a device for notifying the abnormality of the monitoring area to the outside is provided, and the disaster prevention terminal 100 issues an external alarm in conjunction with the notification device (that is, via the notification device). Is also good.

(About the alarm (part 3))
In addition, the warning performed in SA5 of FIG. 4 may be configured to be able to change the warning mode. Specifically, the alarm mode may be changed based on the determination result of the sleep determination unit 71. For example, even in the case of executing SA5, the determination of SA1 and SA2 is repeatedly performed, and when “the determination result of SA1” = “the user is not sleeping” (hereinafter, in the case of awakening), “the determination of SA1” Result = “the user is sleeping” and “the determination result of SA2” = “the user's sleep is not deep” (hereinafter, in the case of light sleep), “the determination result of SA1” = “the user sleeps” In the case of “Yes” and “SA2 determination result” = “Deep sleep of user” (hereinafter, in the case of deep sleep), the alert modes may be different from each other. More specifically, for example, in consideration of the fact that the sleeping user does not easily wake up despite the warning, a predetermined time (for example, 20 seconds) elapses after the warning is performed. In the case of “light sleep” or “deep sleep”, the volume of the audio information output from the speaker 4 in FIG. 2 is increased, or “(alarm (Part 1)), an extended warning such as changing the vibration pattern by the vibration function may be performed. In addition, for example, from the viewpoint of performing an appropriate alarm according to the state of sleep and preventing noise to the neighborhood, "in the case of deep sleep", "in the case of light sleep", and in the case of "awake" A warning may be issued so that the volume of the audio information output from the speaker 4 in FIG. 2 gradually decreases (that is, the maximum volume is for “deep sleep” and the minimum volume is for “awake”).

(Sleep judgment section)
Further, in the above-described embodiment, the case where sleep is determined based on the detection result of the acceleration detection unit in SA1 and SA2 in FIG. 4 has been described, but the present invention is not limited to this. For example, a biological information detection function, which is a function of detecting a user's snoring sound, pulse, or respiratory rate during sleep, is provided in the disaster prevention terminal 100 of FIG. 2, and a detection result of the biological information detection function is used. , Sleep may be determined. Further, for example, by observing the movement of the user's chest using radio waves including microwaves and the like, the respiration rate or respiratory state of the user may be specified based on the observation result, and the determination may be made based on the specified result. .

(About each step of disaster prevention processing)
Further, in the disaster prevention process of FIG. 4 of the above embodiment, some processes may be omitted, changed, or newly added. Specifically, after SA5, a step of determining whether or not to recover (hereinafter, a recovery determination step) and a step of recovering (hereinafter, a recovery execution step) may be provided. Then, in the “restoration determination step”, the control unit 7 of FIG. 2 determines whether or not a predetermined operation input for recovery has been input by the user with respect to the touchpad 2. The “recovery determination step” may be repeatedly executed until an input is made, and when the input is made, the process may shift to a “recovery execution step”. In the “recovery execution step”, the control unit 7 in FIG. 2 may execute the recovery by stopping the alarm performed in SA5 in FIG.

  Further, the abnormality detecting unit 72 may be operated or not operated based on the determination result of the sleep determining unit 71 in FIG. Specifically, after SA6 in FIG. 4 is omitted, when SA1 is NO, SA1 may be repeatedly executed until SA1 becomes YES. In this case, SA2 and SA7 may be further omitted, and SA3 may be executed when SA1 is YES.

(About sensitivity setting)
Further, in the above-described embodiment, the case where the sensitivity for detecting an abnormality is changed by changing the fire determination threshold value used in SA4 in FIG. 4 is described. However, the present invention is not limited to this. For example, the “detection result of the sensor 5” used in SA4 is multiplied by a predetermined coefficient, and the multiplication result is compared with a certain fire determination threshold value. The sensitivity may be changed by adjusting the value of the “predetermined coefficient” (a number larger than 0) after determining whether or not to perform the determination. Specifically, when increasing the sensitivity, “predetermined coefficient” = “number greater than 1”, and when decreasing the sensitivity, “predetermined number” = “greater than 0 and greater than 1”. A "small number" may be used. Further, for example, when an amplification unit such as an amplification circuit is provided in the sensor 5 or the abnormality detection unit 72, the sensitivity may be changed by changing the amplification degree of the amplification unit. Further, for example, when the number of times that the “detection result of the sensor 5” exceeds the fire determination threshold is counted, and a fire is detected based on a comparison result between the count value and a reference value (for example, five times), The sensitivity may be changed by changing the count value or the reference value.

Since the sensor 5 is incorporated in a device, furniture, or bedding provided around the user when the user sleeps, for example, the sensor 5 can be provided around the sleeping user. Can detect a physical quantity to be detected quickly, it is possible to detect the abnormality of the more quickly the monitoring region.

  In addition, at least the abnormality detection unit of the disaster prevention terminal 100 of FIG. 2 is compared with a conventionally used alarm device that is set on a ceiling or a wall (hereinafter, “conventional alarm device”). A function similar to that of the disaster prevention terminal 72 is provided, and the abnormality detection unit 72 is omitted from the disaster prevention terminal 100 of FIG. 2 (note that the disaster prevention terminal 100 omitting the abnormality detection unit 72 is referred to as a “modification disaster prevention terminal”). After having been configured to be able to communicate with the “conventional alarm device” and the “disaster prevention terminal of the modified example” of FIG. 2, after SA1 and SA2 of FIG. Based on the results of SA1 and SA2, the “disaster prevention terminal of the modified example” performs communication control of the “conventional alarm device” so that the “conventional alarm device” performs the same processing as SA3 to SA7. Is also good.

(About application for security purposes)
Further, the security terminal may be configured after each configuration of the disaster prevention terminal 100 in FIG. 2 is changed so that an abnormality related to security can be detected. Specifically, it may be configured as an approach detection terminal that detects intrusion of a suspicious person into the monitoring area as an abnormality in the monitoring area. In this case, an infrared sensor, a temperature sensor, an image sensor, or the like may be provided instead of the sensor 5 in FIG. 2, and the abnormality detection unit 72 in FIG. With such a configuration, it is possible to quickly and reliably detect an abnormality related to crime prevention such as intrusion of a suspicious person, and thus it is possible to improve security in the monitoring area.
