FIG. 3 is a diagram showing a flow of a disaster information collection method by the disaster information collection system. In FIG. 3, processing proceeds in time series from the top to the bottom of the figure.

  In the disaster information collection method, each process is started by operating a portable terminal, for example, a mobile phone 22, possessed by an investigator who went to investigate the disaster area. In the investigation of the disaster situation, for example, a plurality of investigators are assigned to a predetermined area of the disaster area, and the inside of the predetermined area is simultaneously investigated by each investigator. In the present embodiment, a process executed by one investigator will be described.

  The investigator's mobile phone 22 is in a state where the application software downloaded from the disaster information collection server 12 can be activated. In addition, summary information of the master database 14a of the building master operation PC 14 is stored as current summary information in the current storage area 12b of the disaster information collection server 12 in advance. In the disaster information collection server 12, a current summary information update process (S1) is performed in which the stored current summary information is updated at a set time interval, for example, at a predetermined time every day.

  First, the application software downloaded from the disaster information collection server 12 is executed on the cellular phone 22 possessed by the investigator. The mobile phone 22 on which the application software has been executed displays a screen on which operation keys necessary for using the disaster information collection system 10 by the browser function are arranged. When the investigator operates the operation keys displayed on the screen, the following processing of the disaster information collection system is executed.

  Next, the investigator executes the position information function of the mobile phone 22 and uses the GPS to acquire the disaster area position information, which is its own position information.

  Then, the investigator transmits the acquired disaster area location information to the disaster information collection server 12 via the Internet 20 by the HTTPS communication function, and the disaster information collection server 12 receives the location information for receiving the disaster area location information. Process (S2) is executed. The position information acquired at this time does not always indicate the exact position with a pinpoint.

  The disaster information collection server 12 that has received the disaster location information transmitted from the investigator's mobile phone 22 is 5 km square centered on the location specified by the disaster location information based on the acquired disaster location information. Specify the area. At this time, when the latitude and longitude are indicated as the received disaster location information, the location specified by the indicated latitude and longitude is set as the center of the 5 km square area, and the received disaster location When the information is indicated in a predetermined range, a point specified by the latitude and longitude of the center of the indicated range is set as the center of a 5 km square area.

  The disaster information collection server 12 extracts structure information that is included in the identified 5 km square area and extracts the current outline information of the structure from which the damage information is collected from the current outline information stored in the current storage area 12b. Process (S3) is executed. Here, the structure for which the disaster information is collected is, for example, a structure registered in the master database 14a as a construction company or the like that needs to be managed, such as a building, road, or bridge constructed in-house. Pointing.

  The disaster information collection server 12 executes a map information acquisition process (S4) in which the map information of the specified 5 km square area is acquired by accessing the map information distribution server 24 via the Internet 20. The disaster information collection server 12 associates the acquired map information with the positional information included in the current outline information of the structure that is the target of collection of the extracted disaster information, and the disaster location information as the detailed structure information. A transmission process (S5) is transmitted to the mobile phone 22 to which is transmitted.

FIG. 4 is a diagram illustrating an example of display of detailed structure information on the screen of the mobile phone.
As shown in FIG. 4, the cellular phone 22 that has acquired the map information and the current outline information of the structure for which the extracted disaster information is to be collected has a 5 km square by the portable map display function of the activated application software. A map of the area is displayed, and markers 22a, 22b, and 22c are displayed on the displayed map at the positions of the structures that are the collection targets of the disaster information. At this time, the current outline information of the structure for which the disaster information is collected is stored in a memory provided in the mobile phone 22. By clicking on a list of structures linked to the markers 22a, 22b, and 22c displayed on the map, the current outline information can be viewed on the screen of the mobile phone 22.

  The markers 22a, 22b, and 22c are color-coded based on the survey progress information included in the current overview information. For example, when the survey is completed as the survey progress information, the marker 22b is shown in blue (black in FIG. 4), and when the survey is not conducted, the marker 22a is shown in white. In addition, when the survey result is insufficient or during the survey, by using the marker 22c such as yellow or green (gray in FIG. 4), the progress of the survey without clicking the markers 22a, 22b, and 22c. Can be recognized simply by browsing the map. At this time, as shown in FIG. 4, a list 22d of the target structure may be displayed below the displayed map.

  The investigator confirms the position of the structure, for example, the building, from which the disaster information is collected from the markers 22a, 22b, and 22c on the map displayed on the screen of the mobile phone 22, and becomes the target together with the current outline information. Identify the building. Then, the disaster situation of the identified building is photographed by the photographing function provided in the mobile phone 22, and the document data indicating the disaster situation is created and stored in the memory by the data saving function. The photographed photograph data and the created document data are generated as survey report information in association with the registered location information acquired from the current outline information of the building surveyed by the camera-related function, report database function and CSV output function of the application software. The The generated investigation report information is transmitted to the disaster information collection server 12 by the HTTPS communication function, and the disaster information collection server 12 executes investigation report reception processing (S6) for receiving the investigation report information.

  The disaster information collection server 12 that has received the survey report information from the mobile phone 22 transmits the survey report information to the master map database 16a via the LAN 18. A master map information update process (S7) is executed to update the corresponding summary information of the master map database 16a to the survey report information based on the position information included in the received survey report information. At this time, the current outline information of the disaster information collection server 12 is also updated based on the position information included in the investigation report information. By updating the master map database 16a, the disaster information and summary information displayed on the map can be viewed on the map operation PC 16.

  According to the disaster information collection system 10 of the present embodiment, the investigator who investigates the disaster situation includes the area information together with the map information of the area indicated based on the disaster area position information of the current position (point) where the investigator is located. Since the current outline information of the structure to be collected included in the map is acquired in association with the map information, it is possible to easily and accurately specify the structure to be collected in the disaster area. In addition, the current outline information of the structure to be collected is not displayed for a single structure, but for buildings within a 5 km square area. Therefore, each time the structure to be collected is changed, the current outline information is displayed. There is no need to obtain and confirm information. For this reason, since it is possible to schedule the investigation in 5 km square, it is possible to efficiently investigate and collect disaster information.

  Moreover, since the master map database 16a is updated based on the latest survey report information that investigated the disaster situation, it is possible to store the latest disaster information in association with the map information. Then, by updating the master map database 16a, the map operation PC 16 can browse the disaster information and summary information displayed on the map, so that the latest disaster information can be provided more easily.

  In addition, since the current outline information includes registered position information indicating the latitude and longitude of each structure, the position of the structure to be collected is accurately displayed on the map information acquired from the map information distribution server 24. It is possible to display. In other words, even when the current outline information alone can be specified only within a predetermined area, it is possible to accurately specify the structure to be collected based on the registered position information.

  The current storage area 12b and the master map database 16a have investigation progress information for distinguishing between structures that have received the investigation report information and structures that have not been received. Since the information is updated, it is possible to know from the detailed structure information transmitted to the mobile phone 22 whether or not the structure to be collected has been investigated. For this reason, it is possible to prevent duplicating the same structure by different investigators, and it is possible to efficiently conduct the investigation.

  In addition, since the investigation report information includes photos and videos, it is possible to collect and provide clearer disaster information.

  Further, since the summary information of the current storage area 12b is reflected to the master map database 16a via the LAN 18 at regular or irregular intervals when the survey report information is received, the summary information can be always kept up-to-date.

  In the above-described embodiment, the example in which the current outline information of the structure included in the identified 5 km square area and the collection target of the disaster information is extracted from the current outline information stored in the current storage area 12b has been described. At the time of extraction, it is possible not to extract the structure for which the survey has been completed as the survey progress information. In this case, since the extracted current summary information does not include the structure data for which the investigation report information has already been received, it is necessary to investigate the same structure repeatedly by different investigators. It is possible to prevent this, and it is possible to carry out the investigation more efficiently.

  In the above embodiment, the area specified by the disaster information collection server 12 based on the received disaster area position information is set to 5 km square, but the present invention is not limited to this.

  In the above embodiment, an example in which the master database 14a is periodically updated by the administrator of the building master operation PC 14 has been described. However, the master database 14a is regularly or irregularly based on the master map database 16a. It may be updated.

  In the above embodiment, an example in which a mobile phone is used as a mobile terminal has been described. However, the present invention is not limited to this. For example, application software acquired from the disaster information collection server 12 connected to a communication line such as a mobile PC or PDA. Any terminal can be used.

  Moreover, although the said embodiment demonstrated the example which comprised the disaster information collection system 10 connecting the disaster information seed collection server 12, building master operation PC, and map operation PC by LAN18, it does not restrict to this. . For example, the disaster information collection server may include a control unit, a current storage area, a master database, and a master map database.

  The above embodiment is for facilitating the understanding of the present invention, and is not intended to limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
