And a See screen for displaying the response and damage status in a bird's-eye view on a map or table. In addition, the conflict information extraction device of the present invention provides a function particularly related to the See screen.

[Configuration of First Embodiment]
First, the configuration of the first embodiment will be described with reference to FIG. FIG. 2 is a block diagram illustrating a configuration of the map information management device and the conflict information extraction device according to the first embodiment. As shown in FIG. 2, the map information management device 50 and the conflict information extraction device 10 are included in the crisis response system 1, and the client terminal 30 of the countermeasure headquarter 3 and each responsible department 4 by the network 2 capable of data communication. The client terminal 40 is connected.

  First, the map information management device 50 will be described. The map information management device 50 stores map information and displays the stored map information. At this time, the map information management device 50 can also overlay and display a plurality of maps. As shown in FIG. 2, the map information management device 50 includes a storage unit 51 and a control unit 52. The storage unit 51 includes a map information storage unit 511. In addition, the control unit 52 includes a map synthesis unit 521 and a map display unit 522.

  The map information storage unit 511 stores map information. The map information includes a map and information related to the map. The map information storage unit 511 stores a plurality of types of maps with different information to be displayed. For example, the map information storage unit 511 stores a map representing a shelter arrangement, a topographic map, a map representing a power outage area, and the like as a map used particularly for crisis response.

  Further, the information relating to the map includes an ID for identifying the object, the type of the object, the position of the object, the attribute information of the object, the attribute information of a predetermined position or area, and the like.

  The map composition unit 521 displays a plurality of maps on a plurality of different layers and combines the layers by superimposing the layers. The map display unit 522 displays the map and map information stored in the map information storage unit 511, or the map and map information synthesized by the map synthesis unit 521.

  Note that the map and the map-related information stored or displayed by the map information management device 50 are connected via the devices and functions of the crisis response system 1 including the conflict information extraction device 10 or the network 2. It can be referred from each client terminal.

  In the first embodiment, the map information management device 50 provides map information to the conflict information extraction device 10, but the method of providing map information to the conflict information extraction device 10 includes the map information management device 50. It is not restricted to what is used, and any known method may be used.

  Next, the conflict information extraction apparatus 10 will be described. The reciprocal information extraction device 10 extracts reciprocal elements based on a plurality of pieces of map information displayed on different layers acquired from the map information management device 50. A reciprocal element is an object of a map on a layer, and the relationship between the state of the object and the information on the same point on another layer satisfies the conflict condition.

  As shown in FIG. 2, the conflict information extraction device 10 includes a storage unit 11 and a control unit 12. The storage unit 11 includes a condition storage unit 111. The control unit 12 includes a setting unit 121, a determination unit 122, and a notification unit 123.

  The condition storage unit 111 stores a reciprocal condition. The conflict condition is, for example, a combination of a first condition relating to the state of the object and a second condition relating to the damage situation caused by the disaster. The setting unit 121 also accepts registration of reciprocal conditions in the condition storage unit 111 and changes in the reciprocal conditions stored in the condition storage unit 111. In the following description, the first condition may be referred to as a determination target condition, and the second condition may be referred to as a conflict determination condition.

  For example, when it is determined that a shelter during a power outage cannot be opened, the determination target condition may be “the shelter is open” and the conflict determination condition may be “being out of power”. When a shelter that is not in a power outage is to be opened, the determination target condition can be “no shelter has been established” and the conflict determination condition can be “not in a power outage”.

  The determination unit 122 refers to the map information acquired from the map information management device 50 and the conflict condition stored in the condition storage unit 111, and determines whether the object satisfies the conflict condition. For example, the determination unit 122 determines that the state of the object on the first map displayed on the first layer satisfies the first condition and the object on the second map displayed on the second layer. It is determined whether or not the damage situation due to the disaster at the position of the second condition satisfies the second condition corresponding to the first condition.

  If the determination unit 122 determines that both the first condition and the second condition are satisfied, the notification unit 123 notifies information about the object. The notification unit 123 performs notification by transmitting a text message including information on an object determined to satisfy the conflict condition to an external system such as an e-mail or a bulletin board.

  Further, the object to be notified by the notification unit 123 may be arbitrarily selected by setting or the like. For example, an object that satisfies a conflict condition that is not directly related to the business performed by the user and that is not included in the overlay display referred to by the user may not be notified to the user.

  An object that satisfies the conflict condition will be described with reference to FIG. 3, and a specific example of determination of the conflict condition will be described. FIG. 3 is a diagram for explaining an object that satisfies the conflict condition. In the example of FIG. 3, layers 1 to n on which maps are displayed are superimposed and displayed.

  At this time, the map 50a displayed on the layer 1 is a topographic map. Further, the map 50b displayed on the layer 2 and the map 50c displayed on the layer 3 display the damage situation caused by the disaster. The map 50n displayed on the layer n displays whether or not the evacuation shelter can be used and the usage status.

  In addition, the condition storage unit 111 stores that the evacuation shelter on the map is available or in use as a first condition, and that the damage caused by the disaster is such that the evacuation shelter cannot be used. It is memorized as a condition. Specifically, the condition storage unit 111 indicates that a flag indicating whether or not a shelter can be used on the map is usable, or that the number of users is a predetermined number or more as a first condition. It memorize | stores and the electric power is not supplied, or memorize | stores as a 2nd condition.

  Whether the evacuation shelter on the first map is available or in use, and the determination unit 122 has a level of damage caused by a disaster at a position on the second map of the evacuation shelter so that the shelter cannot be used. Determine whether or not.

  The determination procedure will be specifically described. First, the map information of the map 50n stored in the map information storage unit 511 will be described with reference to FIG. FIG. 4 is a diagram illustrating an example of object attribute information.

  As shown in FIG. 4, the map information storage unit 511 has an object ID that is an ID for identifying a refuge, an object name that is a name of the refuge, and a position that represents the position of the refuge in north latitude and east longitude for the map 50n. Information, the opening status indicating the opening status of the shelter, and the number of evacuees indicating the number of evacuees in the shelter are stored. As described above, the map information storage unit 511 stores the position information as part of the attribute information. Further, the establishment status is a flag indicating whether or not the evacuation shelter can be used.

  Further, the map information storage unit 511 stores whether or not a power outage is occurring as attribute information for each coordinate indicated by the north latitude and the east longitude for the map 50c. Further, the map information storage unit 511 stores whether or not the map 50b is flooded as attribute information for each coordinate indicated by north latitude and east longitude.

  First, the determination unit 122 selects the map 50n representing the shelter establishment status as the first map, that is, the determination target map. And the determination part 122 acquires attribute information about the refuge where the object ID on the map 50n is 001, that is, the refuge A. At this time, the determination unit 122 acquires coordinates (N35 ° 39′40 ″, E135 ° 39′10 ″) as the position information of the refuge A.

  Next, the determination unit 122 selects the map 50c representing the power outage area as the second map, that is, the reference target map. Then, the determination unit 122 acquires the attribute information of coordinates (N35 ° 39′40 ″, E135 ° 39′10 ″) on the map 50c, that is, whether or not the position is in a power outage.

  The determination unit 122 may select a plurality of maps as reference maps. For example, the determination unit 122 can select the map 50b representing the flooded area in addition to the map 50c representing the power outage area as the reference target map. At this time, the determination unit 122 acquires the attribute information of coordinates (N35 ° 39′40 ″, E135 ° 39′10 ″) on the map 50b, that is, whether or not the position is flooded.

  Here, the first condition, that is, the determination target condition, and the second condition, that is, the conflict determination condition are acquired from the condition storage unit 111. Here, it is assumed that the determination target condition is “the establishment status is ON or the number of evacuees is 10 or more” and the conflict determination condition is “during power outage or inundation”.

  At this time, since the establishment status of the map 50n of the evacuation shelter A is ON, when the attribute information acquired from the map 50c indicates that a power failure is occurring, the determination unit 122 determines that the evacuation shelter A satisfies the conflict condition. It is determined that Then, the notification unit 123 notifies the warning text message including the name of the evacuation center, “Evacuation center A is open but power is out.”

  Similarly, when the attribute information is similarly acquired from the maps 50c and 50b for the evacuation center whose object ID is 002, that is, the refuge B, the “number of refugees” in the map 50n of the refuge B is 35. For example, when the information acquired from the map 50b indicates that it is flooded, the determination unit 122 determines that the refuge B satisfies the conflict condition. Then, the notification unit 123 notifies a warning text message including the name of the evacuation center, “Evacuation center B has more than 10 evacuees but is flooded.”

[Process of First Embodiment]
Here, the processing of the first embodiment will be described. First, the setting of the reciprocal condition will be described with reference to FIG. FIG. 5 is a flowchart illustrating a processing flow of the setting unit of the conflict information extracting apparatus according to the first embodiment.

  First, as illustrated in FIG. 5, the setting unit 121 accepts the setting of the determination target condition and stores the determination target condition in the condition storage unit 111 (step S <b> 11). Next, the setting unit 121 accepts the setting of the conflict determination condition and stores the conflict determination condition in the condition storage unit 111 (step S12).

  Next, determination of the conflict condition will be described with reference to FIG. FIG. 6 is a flowchart showing a processing flow of the conflict information extracting apparatus according to the first embodiment. First, as illustrated in FIG. 6, the determination unit 122 selects a determination target map from maps displayed on a plurality of different layers (step S <b> 21). Then, the determination unit 122 selects an object from the determination target map, and acquires attribute information and position information of the selected object (step S22).

Furthermore, the determination unit 122 selects a reference target map from among the maps displayed on a plurality of different layers (step S23). And the determination part 122 acquires the attribute information in the position on the map of the reference object of the selected object (step S24).

  Then, the determination unit 122 refers to the determination target condition and the conflict determination condition stored in the condition storage unit 111 (step S25), and determines whether or not the object satisfies the conflict condition (step S26). Specifically, the determination unit 122 determines that when the attribute information of the selected object satisfies the determination target condition and the attribute information at the position on the map of the reference target of the selected object satisfies the conflict determination condition, the object It is determined that

  At this time, when it is determined that the object selected by the determination unit 122 satisfies the conflict condition (step S26, Yes), the notification unit 123 notifies the information about the object (step S27), and ends the process. For example, the notification unit 123 transmits the name of the object and a text message for warning to an external system such as an electronic mail or a bulletin board.

  If it is not determined that the object selected by the determination unit 122 satisfies the conflict condition (step S26, No), the process ends. Note that the determination unit 122 may return to step S22 without ending the process, and further select another object on the determination target map.

[Effect of the first embodiment]
The condition storage unit 111 stores the first condition related to the object status and the second condition related to the damage status caused by the disaster in association with each other. The determination unit 122 then satisfies the first condition on the first map displayed on the first layer and the object on the second map displayed on the second layer. It is determined whether or not the damage situation due to the disaster at the position of the second condition satisfies the second condition corresponding to the first condition. If the determination unit 122 determines that both the first condition and the second condition are satisfied, the notification unit 123 notifies information about the object.

  As described above, according to the first embodiment of the present invention, the user can know the contradictory state of the information included in the first map and the second map without visual observation. Therefore, according to the first embodiment, when information is displayed in a bird's-eye view using a map, it is possible to automatically extract the interrelationship of information included in different maps, and to quickly grasp the situation.

  In addition, when the first map displays availability and usage status of the evacuation shelter and the second map displays the damage status due to the disaster, the condition storage unit 111 can use or use the evacuation shelter on the map. It may be stored as a first condition that it is in the middle, and it may be stored as a second condition that the damage caused by the disaster is such that the shelter cannot be used. In this case, the determination unit 122 is such that the evacuation shelter on the first map is available or in use, and the damage situation due to the disaster at the position on the second map of the evacuation shelter cannot use the shelter. It is determined whether or not. When the determination unit 122 determines that both the first condition and the second condition are satisfied, the notification unit 123 notifies the evacuation center information and a warning text message.

  Specifically, for example, the condition storage unit 111 indicates that a flag indicating whether or not a shelter can be used on the map is usable, or that the number of users is a predetermined number or more. And may be stored as a second condition that a power outage is occurring or water is flooded. This eliminates the need for the disaster response headquarters to visually confirm a plurality of maps, so that it is possible to quickly grasp the situation and take countermeasures.
