Then, the location information calculation unit 1202 digitizes and coordinates the address 1313, and the safety result DB registration processing unit 1203 uses the coordinated address to update the latest location information x (estimation) 1337 and the latest location information y (estimation) 1338. Update.

  The disaster personal information table update unit 1205 also sets the safety confirmation flag 1334 of the disaster personal information table 133 to “0”, the organization code 1316 of the personal basic information table 131 is not NULL, and When the staff flag 1317 is “0” and the kindergarten elementary school flag 1325 of the organization basic information table 132 is “1”, the organization address 1323 of the organization basic information table 132 is currently displayed during the processing time from 9:00 to 15:00. It is estimated that the current position of the guardian is the current position of the individual based on the guardian personal number 1319 of the personal basic information table 131 when the processing time is from 15:00 to 9:00. Then, the current position estimated by the position information calculation unit 1202 is digitized and converted into coordinates, and the safety result DB registration processing unit 1203 uses the current position that has been coordinated to update the latest position information x (determined) 1335 and the latest position information y. (Confirmation) 1336, or the latest position information x (estimation) 1337 and the latest position information y (estimation) 1338 are updated.

  The disaster personal information table update unit 1205 also sets the safety confirmation flag 1334 of the disaster personal information table 133 to “0”, the organization code 1316 of the personal basic information table 131 is not NULL, and If the staff flag 1317 is “0” and the kindergarten elementary school flag 1325 of the organization basic information table 132 is not “1”, the organization address 1323 of the organization basic information table 132 is the current position during the processing time from 9:00 to 17:00. It is estimated that the address 1313 of the personal basic information table 131 is the current position during the processing time from 17:00 to 9:00. Then, the current position estimated by the position information calculation unit 1202 is digitized and converted into coordinates, and the safety result DB registration processing unit 1203 uses the current position that has been coordinated to update the latest position information x (estimation) 1337 and the latest position information y. (Guess) 1338 is updated.

  Note that the processing time in step S701 may be the disaster time, not the time when the program is actually executed. This is because when a large-scale disaster occurs, behaviors different from daily life patterns are taken after the disaster occurrence time.

  Next, a person who needs to be rescued is calculated and a disaster situation map is created (S702). First, in the disaster situation management server 1, the rescue requester calculating unit 1204 recognizes an individual who satisfies a predetermined condition as a rescuer. The rescue-required person calculating unit 1204 calculates a person who needs to be rescued based on the individual basic information table 131, and sets the individual person who needs to be rescued as a person who needs to be rescued in the personal information table 133 at the time of disaster. Update to 1 ”(default is“ 0 ”). For example, it is recommended that the age of 65 years old or older, the disabled person, the elderly living alone, etc. be used as a condition for requiring a rescue request. The priority of rescue may be determined according to the certification condition of the rescue requester, and the rescue requester flag 1333 may be set.

  Next, the disaster situation map (individual) creation processing unit 1206, when the latest position information x (confirmed) 1335 and the latest position information y (confirmed) 1336 of the disaster personal information table 133 are NULL, the latest position information x ( Estimate) Based on 1337 and the latest position information y (estimate) 1338, the distribution of the victims is created and entered in the disaster situation map. The distribution of victims includes the number of persons for each combination of flags for each position (administrative unit such as a grid on a map or a municipality). For example, the number of persons for each flag is “0” for the rescue requester flag 1333 and “1” for the safety confirmation flag 1334 (person who has safely evacuated), “0” for the rescue requester flag 1333 and the safety confirmation flag 1334. Is “0” (unknown safety), the rescue requester flag 1333 is “1”, the safety confirmation flag 1334 is “0” (requires rescue), and their total (total number of victims) It is good to classify. The disaster situation map (individual) creation processing unit 1206 fills in the disaster situation map, for example, the three distributions of the distribution of all disaster victims, the distribution of unaffected disaster victims (excluding those who need rescue), and the distribution of those who need safety certification without confirmation. . You may create the disaster situation map which filled in three distribution mentioned above separately.

  Further, the disaster situation map (organization) creation processing unit 1207 may create a disaster situation map for each organization by a method similar to that for an individual. Furthermore, the disaster situation map (base station) creation processing unit 1208 may also enter the disaster situation of the base station 6 in the disaster situation map. By superimposing the disaster situation of the base station 6 and the distribution of the victims, it is possible to guess an area where the safety cannot be confirmed because the base station 6 is damaged.

  Then, the disaster situation management server 1 transmits the created disaster victim distribution to the fire fighting dedicated terminal 5 (S703).

  The fire fighting dedicated terminal 5 combines the received disaster situation map with the map information stored in the terminal itself and displays the disaster distribution map (S704). In the victim distribution map, the positions and the number of victims are displayed on the map. The number of victims is displayed for each location of the victim distribution (administrative units such as grids and municipalities on the map). The number of victims may be displayed by the size of a circle centered on the map or the color of the grid. Further, the number of persons displayed on the fire fighting dedicated terminal 5 may be selected and displayed according to the input conditions (the number of victims is 10 or more or there are preschool children). For example, when the total number of people including the breakdown is selected for display, the diameter of the pie chart represents the number of victims for each location information, and the breakdown of the number of victims (the person who evacuated safely, It may represent an unanswered person or a rescuer). Only the number of persons requiring rescue may be displayed.

  Further, the base station 6 that is not in operation may be displayed based on the disaster situation of the base station 6 created by the disaster situation map (base station) creation processing unit 1208. This is because it is understood that there is no victim in the area where the base station 6 is not operating, and that it is in a state where contact cannot be made, which is useful for searching for the victim. For example, at the position of the base station 6 that is not in operation, a circle with a diameter corresponding to the number of people detected during operation (before a disaster) (excluding those who have confirmed safety) and non-operation It is good to display.

  The area where the base station 6 is not in operation is estimated to be damaged by the disaster, and the number of victims who cannot be contacted in the area can be estimated.

  When the fire brigade rescues the victim, the rescuer logs in to the disaster situation information creation system with the mobile phone number and name from the fire fighting dedicated terminal 5, and registers the safety of the victim (S705, S706). Based on the safety information registered from the fire fighting dedicated terminal 5, the disaster status management server 1 sets the safety confirmation flag 1334 of the disaster registered in the disaster personal information table 133 to “1” (default is “0”). ")" (S707). The disaster victim distribution is updated by updating the rescue team in the disaster personal information table 133, and the updated disaster situation map is transmitted to the fire fighting dedicated terminal 5. As a result, the rescuer can perform a rescue operation while checking the distribution of the disaster victims that change every moment on the disaster situation map.

  As described above, according to the embodiment of the present invention, the disaster management server 1 acquires the mobile terminal location information including the identification information (mobile phone number) and location information of the mobile terminal device 3 from the mobile communication carrier. Position information based on the mobile terminal position information acquisition step, the safety information acquisition step for acquiring the safety information including the identification information of the mobile terminal device 3, the safety of the victim and the position information, the mobile terminal position information and the safety information The disaster situation information creation step for creating disaster situation information corresponding to safety and safety is executed, and in the disaster situation information creation step, the disaster situation information including the position distribution of those who cannot obtain safety information is created. , You can collect the damage status of the victims.

  Further, since the location information of the mobile terminal device 3 is specified based on the location of the base station 6 connected to the mobile terminal device 3, the location of the victim is automatically specified even if the victim does not report. it can.

  In addition, since the position distribution included in the disaster status information is created based on the position of the base station 6 connected to the mobile terminal device 3, the position of the victim is automatically determined even if the victim does not report. Can be identified.

  In addition, the disaster situation management server 1 acquires the operating status of the base station 6 connected to the mobile terminal device 3 and creates the disaster status information including the operating status of the base station 6. Identify areas where information cannot be collected. Furthermore, by superimposing the damage situation of the base station 6 and the distribution of the victims, it is possible to guess an area where the safety cannot be confirmed because the base station 6 is damaged.

  Further, since the disaster status management server 1 estimates the position information of the person whose safety information has not been acquired based on the history of connection of the mobile terminal device 3 when the non-operating base station 6 is operating, When the terminal device 3 cannot be used or the base station 6 is damaged, it is possible to tabulate the damage status of the victim who is damaged and cannot input safety. As a result, the rescue team can efficiently perform rescue operations.

  The mobile terminal location information includes information on the time when the mobile terminal device 3 is connected to the base station 6, and the safety information includes information on the time when the disaster victim who owns the mobile terminal device 3 inputs safety. Since the disaster status management server 1 creates the disaster status information of the disaster victim who owns the mobile terminal device 3 using the position information at the latest time, the disaster status management server 1 can grasp the real-time disaster status.

  Further, the disaster status management server 1 has a personal basic information table 131 including identification information of the mobile terminal device 3 and a personal number for identifying the victim, and the mobile terminal location information, the safety information, and the personal basic information table 131. Based on the above, the disaster status information of the residents in the disaster area is created, so that the safety of the residents in the disaster area can be confirmed without omission.

  The personal basic information table 131 includes identification information of the organization to which the disaster victim belongs, and the disaster situation management server 1 indicates the location of the disaster victim based on the attribute of the organization to which the disaster victim belongs and the occurrence time of the disaster. Since the estimation is performed, the position of the victim can be accurately estimated based on the normal behavior pattern of the victim.

  In addition, the disaster situation management server 1 creates data for displaying the disaster situation information on the map so that the position and number of the victims can be known, so the disaster situation can be grasped at a glance by superimposing it on the map Can provide data that can.
