The processing performed by each unit of the control unit 33 will be described later.

(processing)
Next, display control processing executed by the disaster prevention system 100 configured as described above will be described. FIG. 5 is a flowchart of display control processing (steps will be abbreviated as “SA” in the following description of each processing). The display control process is a process roughly executed by the center device 3, and more specifically, a process of switching an image displayed on the display device 1. Although the timing to execute this display control process is arbitrary, for example, after turning on the power of each device of the disaster prevention system 100, the execution is started to be repeatedly executed, and the execution will be described from the start. FIG. 6 is a diagram exemplifying an advertisement image, FIG. 7 is a diagram exemplifying an evacuation guidance image, and FIG. 8 is a diagram showing a monitoring area when a fire occurs. Here, for example, as shown in FIG. 8, a case where a fire occurs due to the occurrence of a fire at a fire source F1 located on the east side of the south corridor will be described.

  In SA1 of FIG. 5, the display control unit 334 causes the advertisement image to be displayed. Specifically, although it is arbitrary, for example, it is assumed that a plurality of advertisement images including the advertisement image of FIG. 6 are stored in the recording unit 32, and the plurality of advertisement images which are recorded are displayed By transmitting to 1, the display unit 13 of the display device 1 is displayed. In this case, each display device 1 receives the above-mentioned plurality of advertisement images and stores them in its own recording unit 14 and switches the plurality of stored advertisement images at predetermined time intervals one by one. It will be displayed on the display unit 13 of its own. Here, for example, the advertisement image or the like of FIG. 6 is sequentially displayed on the display unit 13 of the display devices 111 to 117.

  At SA2 in FIG. 5, the detection unit 333 determines whether a fire has occurred. Specifically, for example, when the sensor 2 detects a fire by a known method, a detection signal including the sensor ID of its own is transmitted to the center apparatus 3, and the detection unit 333 Monitors the communication unit 31 to determine whether a fire has occurred based on whether or not the alarm signal has been received. When no alarm signal is received, it is determined that a fire has not occurred and it is determined that a fire has not occurred (NO in SA2), and SA2 is repeatedly executed until it is determined that a fire has occurred. . When the alarm signal is received, a fire is detected, it is determined that a fire has occurred (YES in SA2), and the process shifts to SA3. Here, for example, in FIG. 8, the sensor 212 detects (determines) a fire from smoke from the fire source F1 and generates a report signal including “ID 212” which is its own sensor ID, and the center device 3 In this case, the detection unit 333 detects a fire and determines that a fire has occurred.

  In SA3 of FIG. 5, the image acquisition unit 331 acquires an image (internal image) of the monitoring area. Specifically, although it is arbitrary, for example, first, an image request signal requesting imaging and transmitting an image is generated and transmitted to the display device 1. On the other hand, when the display device 1 receives the image request signal, the image pickup unit 12 picks up an image of the monitoring area, and the date and time when the image pickup is made can be used as a timer (not shown). , And after acquiring its own display device ID, generates an image response signal including the captured image of the monitored area, the specified date and time, and the acquired display device ID, and transmits it to the center device 3 . Next, the image acquisition unit 331 receives the image response signal from the display device 1 and acquires the image of the monitoring area, the date and time, and the display device ID included in the received image response signal, as shown in FIG. A file that stores the acquired display device ID in the display device ID, stores information corresponding to the acquired date and time in the image capturing time information, and can uniquely identify the image of the monitoring area acquired in the image information DB 323 of FIG. The file is given a name and stored, and the given file name is stored in the captured image information of FIG.

  Here, for example, after transmitting the image request signal, as an example, the display device 111 receives the image request signal, the imaging unit 12 images the monitoring area, and “August “18: 00: 45 on 30th” and “ID 111” acquired as its own display device ID, and then an image of the captured monitoring area, “August 30, 18: 00: 45”, And generates an image response signal including “ID 111” and transmits it to the center device 3. Next, the image acquisition unit 331 receives the image response signal from the display device 111, and the image of the monitoring area included in the received image response signal, "August 30, 18: 00:45" , And “ID 111” are acquired, “ID 111” is stored in the display device ID of FIG. 4, “0830180045” is stored in the imaging time information, and the image of the monitoring area acquired in the image information DB 323 of FIG. After storing “File 111 — 1” as an identifiable file name, the file name “File 111 — 1” is stored in the captured image information of FIG. 4. By performing the above-described processing also on the display devices 112 to 117 substantially simultaneously, after acquiring an image, the monitoring information of FIG. 4 is stored.

  The internal number specifying unit 332 specifies the number of people in SA4 of FIG. Specifically, although it is arbitrary, for example, based on the image of the monitoring area acquired by the image acquiring unit 331 at SA3, the number of persons in the monitoring area is specified. Although the specific method here is arbitrary, for example, after performing arbitrary image recognition for each image specified by the captured image information in FIG. 4 and counting the number of subjects in the image, each display device 1 The number of target persons in the vicinity is identified, and information corresponding to the identified number is stored in the number information of FIG. Here, for example, an image specified by “captured image information” = “File 111_1” in FIG. 4 is acquired from the image information DB 323, arbitrary image recognition is performed on the acquired image, and the number of subjects in the image is counted. Then, “5” is identified as the number of target persons around the display device 111, and “5” corresponding to the identified “5” is stored in the number information of FIG. The number of persons in FIG. 4 is stored after specifying the number of persons in the vicinity of the display devices 112 to 117 by performing the above-described process on the display devices 112 to 117 almost simultaneously.

  In SA5 of FIG. 5, the display control unit 334 specifies the fire occurrence position which is the position where the fire has occurred. Specifically, although it is arbitrary, for example, in the image of the monitoring area acquired by the image acquiring unit 331 at SA3, an image including a fire source indicating the occurrence of a fire is specified, and the monitoring information of FIG. 3 identifies the display device ID corresponding to the identified image, and refers to the facility information of FIG. 3 to identify the installation location information corresponding to the identified display device ID, and then identifies the identified installation location. Identify the location of the fire based on the information and display of the above identified image. Here, for example, when the fire source F1 is included in the image captured by the display device 112 in the image of the monitoring area acquired by the image acquiring unit 331 at SA3, the image is identified, and "ID112" is identified as the display device ID corresponding to the identified image with reference to the monitoring information, and "Southern corridor east side" is referred to as installation location information corresponding to the identified "ID112" with reference to the facility information of FIG. After identifying “the south corridor east side” and the display of the identified image described above, the position of the fire source F1 in FIG. 8 is identified as the fire occurrence position.

  The display control unit 334 generates an evacuation guidance image at SA6 in FIG. Specifically, although it is arbitrary, for example, first, the number of subjects identified in SA4 and the fire occurrence position identified in SA5 are acquired, and based on the acquired information, at the position corresponding to the display device 1 Determine the evacuation direction, which is the direction in which the subject should evacuate. Although the decision method of deciding the evacuation direction is arbitrary, it should be decided in consideration of, for example, moving away from the fire source, and being able to evacuate smoothly (that is, avoiding congestion at the entrance and the like), For example, focusing on the number of people information in FIG. 4 (that is, the number of subjects identified in SA4), the number of subjects around each of the display devices 1 is grasped, and the fire occurrence position identified in SA5 is focused Then, after grasping the fire occurrence position, the evacuation method at the position corresponding to each of the display devices 1 is determined. Here, for example, at the position corresponding to the display devices 111 and 113, in particular, "west" and "north side" are determined as the evacuation direction, with the intention of moving away from the fire source F1, and the display devices 112 and 115 are supported. In particular, “east side” and “north side” are determined as the evacuation direction with an intention of moving away from the fire source F1 even in the position where Further, at the position corresponding to the display device 116, particularly, "number of people information" = "5", "20" corresponding to "display device ID" = "ID 111" and "ID 113" in FIG. Based on the number of people in the entire area, it is estimated that the entrance 411 side (that is, the west side) is more likely to be crowded than the entrance and exit 412 side (that is, the “east side”), and the evacuation direction may be vacant. Decide the high "east side". Also, at the position corresponding to the display device 117, similarly, the “east side” which has a high possibility of being vacant as the evacuation direction is determined. In the position corresponding to the display device 114, first, "north side" is determined as the evacuation direction with the intention of moving away from the fire source F1, and further, it branches in the north corridor on the north side. The “east side”, which is likely to be vacant, is also decided as the evacuation direction of

  Next, the display control unit 334 generates an evacuation route, but the generation method of the evacuation route is arbitrary. For example, the total value of the number of people at the junction of the entrance and exit and the evacuation route is calculated. A route may be created. An evacuation route is formed from a location close to the evacuation port where there are few options for evacuation route, and an evacuation route is formed so as to pass a route where the number of people at the junction is small when the evacuation route is formed. In addition, the place where the specific evacuation vulnerable is present may give priority to the creation of the evacuation route. In addition, if there is a direction that you want to guide, such as an evacuation guidance port or a wide passage, define the maximum number of people at the junction in that direction, and give priority to the evacuation route without exceeding the maximum number. good. Then, specifically, the display control unit 334 generates the evacuation route indicated by the arrow based on the determined evacuation direction, acquires the map information of the map information DB 324, and specifies the acquired map information. The generated evacuation route is described on the map, and an evacuation guidance image is generated by displaying an image image of the fire source at the above-mentioned grasped fire occurrence position. Here, for example, the evacuation guidance image of FIG. 7 (an image showing an evacuation direction (direction of arrow) which is a direction in which the object person should evacuate) and an evacuation route (arrow itself) is generated.

  The display control unit 334 causes the evacuation guidance image to be displayed at SA7 in FIG. Specifically, although it is arbitrary, for example, the evacuation guidance image generated at SA 6 is transmitted to the display device 1 and displayed. In this case, for example, the evacuation guidance image of FIG. 7 is displayed on the display unit 13 of the display devices 111 to 117 instead of the advertisement image of FIG. 6 displayed at SA1. In this case, the target person in the monitoring area can evacuate safely and quickly by visually recognizing the displayed evacuation guidance image.

  In SA8 of FIG. 5, the display control unit 334 determines whether or not restoration has been performed. Specifically, although it is arbitrary, for example, when a fire brigade extinguishes and performs a predetermined operation on a receiver (not shown), the receiver transmits a recovery signal to the center device 3, and display control is performed. The unit 334 monitors the communication unit 31 and determines whether or not it has recovered based on whether or not the recovery signal has been received. Then, when the recovery signal is not received, it is determined that the recovery is not performed (NO in SA8), and SA8 is repeatedly executed until it is determined that the recovery is recovered. When a recovery signal is received, it is determined that recovery has been made (YES in SA8), and the process proceeds to SA9. Here, for example, after the initial extinction of the fire source F1 is successful in FIG. 8, when the receiver transmits a recovery signal by performing a predetermined operation on the receiver (not shown), it is determined that the signal is restored.

  In SA9 of FIG. 5, the display control unit 334 causes the advertisement image to be displayed. Specifically, although it is optional, for example, the same processing as SA1 is performed to display the advertisement image. This completes the display control process. Note that, as described above, this display control process is repeatedly executed. However, when an advertisement image is already displayed on the display unit 13 of the display device 1 at SA1 at the time of repetitive execution, The execution of the SA1 may be omitted.

(Effect of the embodiment)
As described above, according to the present embodiment, for example, congestion at the entrances 411 and 412 can be avoided by generating an evacuation guidance image for guiding the evacuation of the subject from the monitoring area based on the number of subjects. Since the evacuation guidance image can be generated, evacuation can be appropriately performed. In addition, until a fire in the surveillance area is detected, the advertisement image is displayed, and when an abnormality in the surveillance area is detected, the evacuation guidance image is displayed instead of the advertisement image, for example, the fire in the surveillance area It is possible to effectively use the display device 1 until detecting the

  In addition, by generating an image indicating an evacuation direction, which is a direction in which the target person should evacuate, as an evacuation guidance image, for example, the target person can be made to recognize the evacuation direction, so evacuation is performed more appropriately. It becomes possible.

  In addition, by identifying the number of persons of the target based on the image of the monitoring area, for example, some load (for example, a tag for performing short distance radio etc.) for specifying the number of persons for the target is held. Since it is possible to specify the number of persons without carrying a portable terminal (for example, holding a smartphone etc.), it is possible to specify the number of persons of the object person without load on the object person.

[Modification to the embodiment]
Although the embodiments according to the present invention have been described above, the specific configuration and means of the present invention can be arbitrarily modified and improved within the scope of the technical idea of each invention described in the claims. Can. Hereinafter, such a modified example will be described.

(About problem to be solved and effect of invention)

(About distribution and integration)
Further, the above-described configuration is functionally conceptual, and does not necessarily have to be physically configured as illustrated. That is, the specific form of the distribution and integration of each part is not limited to the illustrated one, and all or a part thereof can be configured to be functionally or physically dispersed or integrated in any unit. In addition, the “device” in the present application is not limited to one configured by a single device, but includes one configured by a plurality of devices. For example, the center device 3 is configured to be distributed to a plurality of devices configured to be mutually communicable, and a part of each part of the control unit 33 is provided in a part of the plurality of devices. Another part of each part of the control unit 33 may be provided in another part. In addition, at least a part of the information recorded in the center device 3 or at least a part of each part of the control unit 33 may be provided in each display device of the disaster prevention system 100. Alternatively, the imaging unit 12 of the display device 1 may be provided as a separate device separated from the display device 1.

(About identification of the number of people inside)
Although it is preferable to specify the number of internal persons based on an image so as not to increase the operation (that is, the load) of the object person, other methods may be used. For example, in the case of a floor where entry and exit management is performed for each area, the number of internal persons may be specified based on entry and exit information. Alternatively, a tag or the like that performs short distance wireless communication may be delivered to the target person at the entrance or the like, and a receiver that receives a wireless signal from the tag may be provided at each location to count the number of people at each location. Further, communication may be performed on a portable terminal (for example, a smartphone or the like) held by the target person using a technology such as short distance wireless communication, and the number of persons may be counted by a reply from the portable terminal. Other appropriate methods may be taken.

(About judgment of fire)
Further, in the above embodiment, the detection unit 333 determines a fire based on the alarm signal in SA2 of FIG. 5, but the fire may be determined based on the alarm signal and the image, or the fire only based on the image May be determined.

  In the case of determination based on the alert signal and the image, specifically, a fire occurs when an alert signal is received and a fire source or the like is confirmed from an image around the sensor 2 that has transmitted the alert signal. It may be determined that the In this case, the detection unit 333 performs appropriate communication to detect a fire in the monitoring area of the plurality of sensors 2 based on the sensor ID in the alarm signal and the facility information in FIG. The display device 1 closest to the position of the at least one sensor 2 identified by the plurality of display devices 1, and based on the internal image captured by the imaging unit 12 included in the identified display device 1; You may detect a fire. Here, for example, when an alert signal from the sensor 212 is received, a fire in the monitoring area of the plurality of sensors 2 is detected based on “ID 212” in the alert signal and the facility information of FIG. The display device 112 closest to the detected (judged) position of at least one sensor 212 is specified by the plurality of display devices 1, and based on the internal image captured by the imaging unit 12 included in the specified display device 112, A fire in the surveillance area may be detected. When configured in this manner, the display unit 112 that is the display unit 1 closest to the position of the sensor 212 that is the at least one sensor 2 that has determined the fire is identified, and the imaging unit 12 included in the identified display unit 112 By detecting the fire in the monitoring area based on the internal image captured by the camera, for example, the fire in the monitoring area can be detected using the internal image in addition to the determination result by the sensor 2. It is possible to improve fire detection accuracy.

  Moreover, about the case where a fire is determined only by an image, specifically, the center device 3 acquires and acquires an image captured by the display device 1 at predetermined time intervals (for example, 2 seconds to 5 seconds etc.) The image may be used to determine a fire.

  In addition, the internal image captured by the imaging unit 12 included in the display device 112 that is the display device 1 closest to the position of the sensor 212 that is the at least one sensor 2 that has determined the fire is not subjected to the fire determination. Even if the internal image is displayed on the display surface (not shown) of the center device 3 (other display means) (for example, any display etc.) and / or the display unit 13 of the other display device 1 to make the disaster prevention personnel aware good. When configured in this manner, for example, since the disaster prevention personnel can easily check the internal image, the warning operation can be performed at an early stage when the disaster prevention personnel determine whether the internal image is a real fire. Further, the disaster prevention personnel may determine the fire by the operation of the center apparatus or the operation of the display device 1 when it is determined that the fire is a fire by confirming the internal image.

(About evacuation guidance image (1))
Further, in the above embodiment, the case of generating the evacuation guidance image of the evacuation route of FIG. 7 was described in SA6 of FIG. 5, but any image may be generated as the evacuation guidance image as long as evacuation guidance can be performed smoothly. You may For example, for the evacuation guidance image of FIG. 7, the location of the display device 1 for displaying the image is identified from the facility information of FIG. 3 and an image of the identified location (for example, a circle and “the current position is here Etc.) may be attached. Here, for example, regarding the evacuation guidance image displayed on the display device 111, an image of the location of the display device 111 may be added to the evacuation guidance image of FIG. Further, for example, an image (for example, an arrow image) indicating the evacuation direction described in SA6 instead of the evacuation guidance image of FIG. 7 is generated for each display device 1 that displays the image, and the generated image is an evacuation guidance image It may be displayed as Here, for example, since “west” is determined as the evacuation direction for the display device 111, the display device 111 uses an arrow image pointing west with respect to the subject who visually recognizes the display device 111 as the evacuation guidance image. It may be displayed.

  FIG. 9 is a view exemplifying an evacuation guidance image of a modification. Then, for example, as shown in FIG. 9, a fire display (for example, the characters “fire occurrence” in FIG. 9), an arrow image indicating the evacuation direction, and an entire map such as the evacuation guidance screen in FIG. You may Further, the entire map may display the image of the place of the display device 111 as described above, and the evacuation route may display only the one from the place of the display device 111. In addition, the display screen may be able to be scaled, switched, and the like when the target person operates each image on the display device 111.

(About evacuation guidance image (2))
Moreover, although the said embodiment demonstrated the case where an evacuation guidance image was produced | generated based on the number of persons of each display apparatus 1 which the number information of FIG. 4 shows, as long as evacuation guidance can be performed smoothly, arbitrary images are You may produce | generate as an evacuation guidance image. For example, the evacuation guidance image may be generated based on the total number of people information in FIG. 4 (that is, the number of subjects in the entire monitoring area). Specifically, for example, when there are a large number of people, the number of target persons is a predetermined number (for example, 100 people), paying attention to the possibility that the entrance will be crowded and a secondary disaster may occur due to falling etc. In the case of less than 120 people, the message "Please evacuate immediately" is attached to the evacuation guidance image of Fig. 7, while the number of target persons is more than a predetermined number (for example, 100 to 120 etc.) In the case, the message "Please calmly evacuate" may be attached to the evacuation guidance image of FIG.

(About evacuation guidance image (3))
For example, when a building has a plurality of floors, such as five floors, the evacuation guidance image for each floor may be generated based on the total number of people for each floor target person. Alternatively, in this case, in order to evacuate each floor sequentially, evacuation guidance images may be sequentially displayed. Also, for example, when the building is a hospital, the number of persons with difficulty in evacuation may be stored based on the medical condition, and the number of persons with difficulty in evacuation or the location of the persons with difficulty of evacuation may be displayed on a display device in the hospital. . With such a configuration, it is possible to appropriately support evacuation of a person who has difficulty in evacuation.

(About evacuation guidance image (4))
Moreover, you may change the display mode of the evacuation guidance image of SA7 of FIG. 5 of the said embodiment arbitrarily. For example, as described in the embodiment, the evacuation guidance image may be displayed instead of the entire advertisement image (that is, the evacuation advertisement image may be displayed by erasing the advertisement image). The evacuation guidance image may be displayed instead of a part of the advertisement image (that is, part of the advertisement image (eg, part of the lower right, etc.) is erased, and the evacuation guidance image is displayed on the erased part May be displayed).

(About analog value)
Further, in SA6 of FIG. 5 according to the above-described embodiment, after the center device 3 side can acquire the analog value (for example, the density of smoke) of each sensor 2 from the sensor 2, this sensor can be obtained. (2) Based on each analog value, the direction in which the fire is spreading may be identified, and in consideration of this direction, the evacuation direction may be determined or an evacuation route may be generated.

(About refuge number identification part, incomplete number of people identification part, and output part)
Further, the control unit 33 of the center device 3 may be provided with an evacuation number identification unit, an incomplete number identification unit, and an output unit. The “displacement number identification unit” is an evacuation number identification means for identifying the number of persons evacuated from the monitoring area, and the “incomplete number identification portion” is the number of persons identified by the evacuation number identification means, It is an incomplete number of people identification means for identifying the number of subjects who have not completed evacuation within the target area based on the number of people identified by the internal number identification means, and the “output unit” is It is an output means for outputting the number of people specified by the incomplete people number specifying means. Although the specific mounting method of these units is arbitrary, for example, the following processing may be performed.

  First, after displaying the evacuation guidance image at SA7 in FIG. 5, the evacuation people identification unit performs appropriate communication, and the imaging unit 12 of the display devices 116 and 117 picks up the periphery of the entrance 411 and 412. And acquiring the captured image, and identifying the number of the evacuated target persons from the acquired image. Next, based on the number of people specified by the number-of-disqualified-people specifying unit and the total number of people specified by the internal-number specifying unit 332 at SA4 (for example, the total of the number information of FIG. 4). By subtracting the number of people specified by the number-of-displacements-specification unit from the total, the number of persons of the target who have not yet completed evacuation within the target area is specified. Next, the output unit outputs, by any means, the number of people specified by the incomplete person number specifying means. The output here is displayed on a display (not shown) of the center device 3, output as voice by a speaker (not shown), or communication output to a fireman via the communication unit 31. You may When configured in this manner, for example, evacuation of persons who support evacuation (for example, firefighters, etc.) is completed by outputting the number of persons whose evacuation has not been completed yet within the target area. Since the number of non-target persons can be recognized, evacuation support can be appropriately performed, and the safety of the target persons can be secured.

(About other functions)
Also, for example, each display device 1 transmits the advertisement image or the evacuation guidance image to a portable terminal (for example, a smartphone or the like) held by a target person in the vicinity of the user using a technology such as short distance wireless communication. Then, the image may be displayed on the portable terminal. When configured in this manner, the target person can view his / her portable terminal even if it is difficult to view the display device 1 due to an obstacle or the like, and thus can escape appropriately.

  Further, for example, the information in each image described in the embodiment or the modification may be output as an audio. In addition, when the subject visually recognizes each display device 1, the image recognition is performed on the subject with each display device 1, the nationality of the subject is estimated, and information in a language corresponding to the estimated nationality May be output, or information of a language corresponding to the estimated nationality may be transmitted and displayed on the mobile terminal of the target person.

  Also, for example, a television conversation may be performed between the display device 1 side and the receiver side (not shown) by using the determination that a fire has occurred as a trigger.
