  FIG. 7 schematically shows the processing flow of the emergency evacuation application of the application processor 10a in the smartphone 10, and FIGS. 8 and 9 show examples of screens displayed on the display 10j in that case. Schematically shows the system configuration constructed by this emergency evacuation application. However, the present embodiment describes a case where an application that performs emergency evacuation due to the occurrence of a huge earthquake is executed as an emergency evacuation application.

  When the earthquake early warning (the epicenter, epicenter depth, magnitude, and earthquake occurrence time) is received from the Meteorological Agency's earthquake early warning device 14 via J-ALERT, the earthquake early warning server 13 determines the ground coefficient and smartphone from the earthquake early warning. Information (the epicenter, the predicted seismic intensity, and the estimated arrival time) analyzed based on the ten current locations is immediately transmitted to the dedicated server 12. The dedicated server 12 transmits emergency evacuation information to the smartphone 10 immediately after receiving the earthquake early warning and its analysis information.

  Upon receiving this emergency evacuation information, the smartphone 10 that is executing a normal application such as a tourist guide interrupts the normal application and immediately starts the emergency evacuation application whose processing flow is shown in FIG. First, the application processor 10a displays the information provided by analyzing the earthquake early warning on the display 10j (step S11). The analysis information of this earthquake early warning includes the epicenter, predicted seismic intensity, and expected arrival time.

  FIG. 8 shows an example of the earthquake early warning displayed on the display 10j in this case. As shown in the figure, in this example, on the display 10j, an epicenter 80 “Occurrence of offshore earthquake”, an expected seismic intensity 81 “high 5”, and an estimated arrival time “28 seconds until the earthquake” are shown. 82, and an evacuation guidance start button 83 for the user requesting evacuation guidance is displayed.

  Simultaneously with this display, the application processor 10a has only the divided map information of a plurality of (about 9 to 15) small sections (tiles) about at least one scale around the current location of the smartphone 10 in the background. Is quickly acquired from the map server 11 and stored in the cache in the CPU, and at the same time, the location information of a plurality of evacuation support centers in a predetermined area (for example, a predetermined municipality) is acquired from the dedicated server 12 and this cache in the CPU is acquired. Further, a numerical value (seconds) corresponding to the expected arrival time 82 is counted down every second (step S12). Here, the evacuation support center corresponds to an evacuation center, a place where an AED is installed, and / or a medical facility. The current location is constantly updated by the GPS signal from the GPS satellite 15.

  Next, the application processor 10a compares the distance between the current location updated and acquired by GPS and the positions of a plurality of evacuation support centers stored in the cache, and determines the evacuation support station having the shortest distance as the nearest evacuation support station. (Step S13).

  Next, the application processor 10a connects the current location to the nearest evacuation support center with a straight line and divides it into a plurality of equal parts (step S14).

  Next, the application processor 10a quickly acquires from the map server 11 the divided map information of a plurality of (about 9 to 15) subsections on at least one scale around the nearest evacuation support center, and the CPU. The map server 11 stores the divided map information of a plurality of subsections (about 9 to 15) about at least one scale around the position of the division points divided into a plurality of equal parts. It is quickly acquired and stored in the cache in the CPU (step S15). In this case, the divided map information is acquired from the map server 11 in the order of the nearest evacuation support station, the division point closest to the nearest evacuation support station, and then the division point from the division point to the current location. However, this acquisition order is not limited to this. By acquiring such map information, all map information up to the nearest shelter is acquired and stored in a cache in the CPU. Moreover, this information is acquired and stored in the cache within a time period (several seconds to several tens of seconds) from the arrival of the P wave and the occurrence of the earthquake early warning to the arrival of the S wave that may cause the communication facility to collapse. Will be performed.

  Next, the application processor 10a creates an evacuation guidance route to the nearest evacuation support center determined from the current location (step S16). So far, it is done in the background.

  Next, the application processor 10a determines whether or not the evacuation guidance start button 83 displayed on the display 10j has been touched (step S17). If it is determined that the touch has been made (YES), the current location, the nearest evacuation support center, and the created evacuation guidance route are displayed on the display 10j (step S19). If it is determined in step S17 that the evacuation guidance start button 83 is not touched (in the case of NO), it is determined whether or not the countdown is performed until the numerical value corresponding to the expected arrival time 82 becomes zero (step S18). When it is determined that it has become zero (in the case of YES), in step S19, as described above, the current location, the nearest evacuation support center, and the created evacuation guidance route are displayed on the display 10j. When it is determined that it is not zero (in the case of NO), the process returns to step S17 and the above determination is repeated. As a result of the above operation, when the evacuation guidance start button 83 is touched by the user or the estimated arrival time 82 is reached, the evacuation guidance route is displayed on the display 10j.

  FIG. 9 shows an example of the evacuation guidance screen displayed on the display 10j in this case. On this screen, an evacuation guidance route 92 from the current location 90 to the nearest evacuation support center 91 that is the destination is shown on the map, and the nearest evacuation support center 91 “250 m to the evacuation support center” is displayed. Distance 93 is shown.

  As shown in FIG. 10, the emergency evacuation application allows the smartphone 10 to constantly update and acquire its current location with a GPS signal from the GPS satellite 15, and around the current location. Emergency evacuation map information acquisition means 101 that acquires divided map information of a plurality of small sections (tiles) for at least one scale from the map server 11 and evacuation that acquires position information of a plurality of evacuation support centers from the dedicated server 12 Support location information acquisition means 102, emergency location storing current location acquisition means 100, emergency evacuation map information acquisition means 101, current location acquired by evacuation support location information acquisition means 102, divided map information, and location information of multiple evacuation support locations Evacuation information storage means (cache) 103 and current location stored in cache 103 Create the nearest evacuation support center discriminating means 104 for determining the nearest evacuation support center from the location information of multiple evacuation support centers and the evacuation guide route from the current location to the nearest evacuation support location, and the current location and the nearest evacuation support The guidance display instruction means 105 for instructing the display of the place and the evacuation guidance route and the display means 106 for performing the display are constructed. However, the emergency evacuation map information acquisition means 101 has a plurality of at least one scale about the position of a division point that is divided into a plurality of equal parts connecting the updated current location to the nearest evacuation support center at the time of emergency evacuation. Divided map information of small sections and divided map information of a plurality of small sections about at least one scale centered on the location of the nearest evacuation support center are acquired and stored in emergency evacuation information storage means (cache) 103 It is configured to let you. The guidance display instruction unit 105 causes the display unit 106 to display the created evacuation guidance route when the evacuation guidance start button is operated by the user or when the emergency occurrence expected time (expected arrival time) is reached. It is configured as follows.

  As described above, according to the present embodiment, during emergency evacuation, execution of the normal application up to that point is interrupted, and the application is forcibly switched to the emergency evacuation application. That is, only the divided map information of a plurality of (9 to 15) small sections about at least one scale centered on the current location of the smartphone 10 is acquired from the map server 11 and the location information of the plurality of evacuation support centers from the dedicated server 12. Force the process to get. The acquired divided map information and the position information of a plurality of evacuation support centers are stored in a cache, and the nearest evacuation support station is determined from the current location and the position information of the plurality of evacuation support stations. Next, an evacuation guidance route from the current location to the nearest evacuation support center is created in the background, and is displayed on the display 10j when the evacuation guidance start button is touched or the expected arrival time is reached. If the emergency evacuation is an evacuation due to the occurrence of a major earthquake, the minimum necessary map information (centered on the current location) will be required within a few seconds to several tens of seconds after the early warning is issued and the radio facility collapses and becomes unable to communicate. And the evacuation support center information is stored in the cache of the smartphone 10, so even after the communication facility collapses and becomes unable to communicate, the smartphone 10 itself If is operable, a map from the current location to the nearest evacuation support center can be displayed reliably, and the user can be guided safely and reliably. Instead of displaying the evacuation guidance route from the current location to the nearest evacuation support center, the direction from the current location to the nearest evacuation support location may be displayed with an arrow.
