Or send it to a remote location.

  The GPS function part 103 calculates the coordinate which shows the position of the portable terminal 100 on the ground by processing the signal received via the antenna in the portable terminal 100 from the GPS satellite. By providing the GPS function unit 103, the mobile terminal 100 exhibits a current position detection function for detecting the current position of the mobile terminal 100.

  The memory 105 stores data such as an operating system, a map application (hereinafter referred to as “app”), a program such as an evacuation mode application, and data that may be used in a portable terminal such as an e-mail, an address book, and user information. . The memory 105 stores map data.

  Map data includes basic map data such as roads, sidewalks, and passages placed on the ground, and attached information on restaurants, commercial facilities, stations, buildings, government offices, sightseeing spots, etc. displayed on the map indicated by the basic map data. , And is composed of general map data including both. That is, the general map data includes information for specifying a general commercial facility. The structure of this general map data is a layer structure composed of basic road data, detailed road data, etc. constituting basic map data and building information, character data, shape data, background data, etc., which are auxiliary information. It has become. Then, the control unit 104 causes the display unit 107 to display data obtained by combining these data. The attached information includes basic attribute information indicating an address code, a block code, an address, a house number, a name, and the like.

  Further, the map data includes recommended evacuation site position information and attribute information thereof. This recommended evacuation area includes not only a place designated as an emergency evacuation place but also a building or a place not designated as an emergency evacuation place. Recommended evacuation sites include, for example, buildings that meet the new seismic standards based on the Building Standards Act (June 1, 1981, revised Building Standards Act Enforcement Ordinance), and the Building Standards Act of June 1, 2000 Buildings built on the basis of the revision of the construction order, “National Network Committee for Promotion of Seismic Diagnosis and Rehabilitation of Existing Buildings” (abbreviated as “National Seismic Network Committee”) Buildings that have been designated as such, buildings that have the Tokyo Earthquake Resistant Mark, etc. are included. In addition, the recommended evacuation sites include buildings and places that are highly safe for disaster prevention through independent surveys or verifications by the creator of general map data. However, the recommended evacuation site is a combination of one that includes only the emergency evacuation site, one that includes a part of the emergency evacuation site, or one that includes a part of the emergency evacuation site and an additional building or area. May be. For example, recommended evacuation sites may include all buildings that meet the new earthquake resistance standards.

  The attribute information is, for example, whether the recommended evacuation site is a building or a land such as a park or vacant land, or the earthquake intensity that the building can withstand, the height of the recommended evacuation site, the distance from the coastline or river of the recommended evacuation site It is information about etc.

  The map app is for displaying the current location and the route to the destination. The destination is selected by the user inputting a destination name and attributes (for example, a station, a post office, a recommended evacuation site, etc.) via the operation unit 108. However, when a predetermined condition related to the destination is set in advance, the mobile terminal 100 allows the route from the current position to the destination even when there is no input of the destination name or the like via the operation unit 108 by the user. Can be displayed.

  The evacuation mode application switches the operation mode of the mobile terminal 100 to the evacuation mode when the emergency bulletin is received. In this evacuation mode, the nearest recommended evacuation site, which is a recommended evacuation site located within a predetermined distance from the current position of the mobile terminal 100, and the evacuation from the current location of the mobile terminal 100 to the nearest recommended evacuation site. This is an operation mode for displaying a route. Here, the “nearest recommended evacuation site” does not necessarily mean the recommended evacuation site having the shortest straight line distance from the current position of the mobile terminal 100, but the length of the arrival route from the current position of the mobile terminal 100. Means the shortest recommended evacuation site. The “nearest recommended evacuation site” is not limited to one recommended evacuation site, and may be a plurality of recommended evacuation sites. Then, when the operation mode of the mobile terminal 100 is switched to the evacuation mode, the map application is activated, and the map application is located within a predetermined distance range from the current position of the mobile terminal 100, and the mobile terminal The evacuation route from the current position of 100 to the recommended evacuation site is displayed.

  Here, emergency warning is “emergency earthquake warning”, “large tsunami warning”, “tsunami warning”, “special warning” delivered by the Japan Meteorological Agency, etc., or “disaster / evacuation information” delivered by the national / local government And the like. The emergency bulletin includes bulletin type information for identifying the type of information notified by these emergency bulletins. Further, the emergency bulletin includes, for example, information on the position (latitude / longitude) where the disaster occurred and the scale of the disaster. For example, the emergency bulletin for notifying the occurrence of an earthquake includes information indicating the position where the earthquake occurred, the energy of the earthquake, and the depth of the epicenter.

  The emergency bulletin is broadcast (broadcast) from the base station of the mobile phone operator to the user's mobile terminal in the target area selected by the mobile phone operator. The evacuation mode application is automatically activated when the mobile terminal 100 is turned on. In addition, the evacuation mode application executes selection of whether or not to switch the operation mode of the mobile terminal 100 to the evacuation mode according to the type and degree of disaster included in the received emergency bulletin. For example, as described above, in the case of a tsunami warning, there are two types, a large tsunami warning and a tsunami warning. Here, the evacuation mode application switches the operation mode of the mobile terminal 100 to the evacuation mode when receiving the emergency bulletin for notifying the large tsunami warning. However, if the emergency evacuation for notifying the tsunami warning is received, the operation of the mobile terminal 100 is performed. Do not switch modes.

  The control unit 104 includes a microprocessor. The control unit 104 reads and executes a program stored in the memory 105, thereby executing an emergency bulletin receiving unit 1041, a map display unit 1042, an operation mode switching unit 1043, a positioning unit 1044, an attribute specifying unit 1045, a recommended evacuation site specifying unit. 1046, evacuation route identification unit 1047, danger range identification unit 1048, map update unit 1049, setting unit 1050, safety determination unit 1051, notification unit 1052, movement direction identification unit 1053, and icon display unit 1054. The emergency bulletin receiving unit 1041 receives the emergency bulletin via the communication circuit 102.

  The operation mode switching unit 1043 switches the operation mode of the mobile terminal 100 to the evacuation mode when the emergency bulletin reception unit 1041 receives the emergency bulletin. Here, the operation mode switching unit 1043 switches the operation mode of the mobile terminal 100 to the evacuation mode according to the bulletin type information included in the emergency bulletin.

  The setting unit 1050 sets whether or not the operation mode switching unit 1043 switches the operation mode of the mobile terminal 100 to the evacuation mode.

  When the operation mode of the mobile terminal 100 is switched to the evacuation mode, the map display unit 1042 acquires map data from the memory 105 and displays the nearest recommended evacuation place and evacuation route on the display unit 107 using the acquired map data. . Further, when the operation mode of the mobile terminal 100 is the normal mode, the map display unit 1042 acquires map data from the memory 105 when the user performs an operation for displaying a map on the display unit 107 with respect to the operation unit 108. Then, a map is displayed on the display unit 107.

  The positioning unit 1044 causes the GPS function unit 103 to calculate coordinates indicating the current position of the mobile terminal 100 and acquires the coordinates calculated by the GPS function unit 103. The positioning unit 1044 stores the acquired current position information in the memory 105 every time it acquires current position information indicating the current position of the mobile terminal 100. As a result, the memory 105 stores a history of past location information of the mobile terminal 100.

  The moving direction specifying unit 1053 specifies the moving direction of the portable terminal 100 from the position of the portable terminal 100 obtained by positioning in the past indicated by the position information stored in the memory 105 and the current position of the portable terminal 100.

  The icon display means 1054 generates a footprint icon (movement direction presentation icon) having a footprint shape indicating the movement direction of the mobile terminal 100 based on the movement direction of the mobile terminal 100 specified by the movement direction specification means 1053. Then, the icon display means 1054 causes the display unit 107 to display the generated footprint icon on the map corresponding to the map data.

  The safety determination unit 1051 decodes the content of the received emergency bulletin, acquires the map data stored in the memory 105, and based on the content of the emergency bulletin and the information included in the map data, the current position of the mobile terminal 100 Judge the safety of. Here, the safety determination unit 1051 refers to the map data, and based on the information indicating the type and scale of the disaster included in the emergency bulletin, is the current position of the mobile terminal 100 safe or dangerous? Determine.

  The notification unit 1052 generates notification information to be notified to the user via the display unit 107 based on the determination result by the safety determination unit 1051 and stores the notification information in the memory 105. And the notification means 1052 acquires the notification information memorize | stored in the memory 105, and displays it on the display part 107 in the form of overlapping notification information on the map corresponding to map data. Here, when the operation mode of the mobile terminal 100 is the normal mode after receiving the emergency bulletin, the notification unit 1052 displays the notification information on the display unit 107 after a preset standby time has elapsed. Overlay text information and icons. On the other hand, the notification unit 1052 displays the notification information 301 on the map displayed on the display unit 107 when the operation mode of the mobile terminal 100 is switched to the evacuation mode after receiving the emergency bulletin, The notification information display is canceled after a preset period has elapsed.

  The attribute specifying unit 1045 specifies attribute requirements that the recommended evacuation site should have in accordance with the emergency bulletin.

  The recommended evacuation site specifying unit 1046 specifies a recommended evacuation site that is located within a preset distance from the current position of the mobile terminal 100 and satisfies the attribute requirements specified by the attribute specifying unit 1045.

  The evacuation route specifying unit 1047 specifies an evacuation route from the current position of the mobile terminal 100 to the recommended evacuation site specified by the recommended evacuation site specifying unit 1046.

  The danger range specifying means 1048 specifies a danger range that is a possible range of danger due to a disaster based on information included in the emergency bulletin.

  The map update means 1049 periodically connects to the network via the communication circuit 102 and acquires the latest general map data and evacuation map data from an external map server.

  The power control unit 106 plays a role of switching between a normal operation and a power saving operation in which power consumption is reduced more than usual in accordance with an instruction from the control unit 104. When the power control unit 106 switches to the power saving operation, for example, the communication function in the communication circuit 102 is temporarily interrupted, the brightness of the display unit 107 is reduced, and the operation speed (clock speed) of the control unit 104 is reduced. Power consumption is reduced.

  The display unit 107 is usually a dot matrix composed of a large number of minute light emission points, a group of semiconductor switches connected to each of the large number of light emission points, and a filter. This type of display unit 107 is generally composed of liquid crystal or OLED (Organic Light Emitting Diode). In the display unit 107, the image seen from the surface changes when the light emission point is partially turned on and off by the semiconductor switch group. The general map data or the evacuation map data according to the present invention is displayed on the display unit 107.

  The operation unit 108 is composed of a switch group that accepts an operation from the user with respect to the portable terminal 100, and is generally configured by a pressure sensor and a push button. Here, when the user operates the operation unit 108 and performs an operation of selecting one of the icons of the plurality of applications displayed on the display unit 107, the control unit 104 activates the application corresponding to the selected icon. . Then, when the user performs a predetermined operation on the operation unit 108 in a state where the application is activated, the control unit 104 executes a predetermined program corresponding to the activated application.

  The voice input / output unit 109 has a microphone and a speaker, and performs voice input / output.

  FIG. 1 is a block diagram showing the main functions in the mobile terminal. Components such as a control unit and a memory may be distributed in a plurality of LSIs or IC chips. Is not necessarily physically separated. Therefore, for example, the communication circuit 102 and the GPS function unit 103 may be integrated, and the power supply control unit 106 may be a part of the control unit 104. Note that a commercially available digitizer has a pressure-sensitive sensor disposed on a display unit, and the functions of the display unit 107 and the operation unit 108 are integrated. Further, generally, each element is configured from a semiconductor product in which a control unit and a memory are individually integrated.

  The setting as to whether or not the mobile terminal 100 can perform the operation transition to the evacuation mode can be performed in the initial setting of the mobile terminal 100. This setting can also be performed by performing a setting operation in the evacuation mode app and a release operation for releasing the operation in the evacuation mode on the mobile terminal 100 during the evacuation mode app operation. In accordance with this setting, it is determined whether or not the operation mode can be switched to the evacuation mode displaying the nearest recommended evacuation site.

  The manual stop of the evacuation mode may or may not be necessary to evacuate immediately depending on the content of the displayed emergency bulletin, so that the user can select the judgment. For example, when a user is on an upper floor in a safe high-rise building based on seismic design, it is rather than immediately going to an evacuation site when an earthquake or tsunami occurs. This is because it may be preferable to stay on the spot.

  Next, mobile terminal control processing executed by the control unit 104 of the mobile terminal 100 according to the present embodiment will be described with reference to FIGS. This portable terminal control process is started when the portable terminal 100 is turned on. 2, 3, and 5 are sequentially processed by the control unit 104 reading and executing a mobile terminal control processing program stored in the memory 105. First, the emergency bulletin receiving unit 1041 determines whether or not an emergency bulletin has been received (step S101).

  If the emergency bulletin receiving unit 1041 determines that no emergency bulletin has been received (step S101: No), the mobile terminal 100 continues the normal process (step S102). At this time, the mobile terminal 100 appropriately executes a call, communication, activation of various applications, and the like according to a user operation. Thereafter, the process of step S101 is executed again.

  On the other hand, when the emergency bulletin receiving unit 1041 determines that the emergency bulletin has been received (step S101: Yes), the safety determination unit 1051 decodes the content of the received emergency bulletin (step S103). This emergency bulletin may be composed of a specific code that cannot be identified by the user itself, or may be composed of a text message, an e-mail, or the like that displays the type of disaster intended to be read by a person. Here, the safety determination unit 1051 decodes information indicating the type and scale of the disaster included in the emergency bulletin, and stores the information obtained by the decoding in the memory 105.

  Next, the safety determination unit 1051 acquires map data stored in the memory 105 (step S104).

  Next, the operation mode switching unit 1043 determines whether or not the setting unit 1050 has been set to switch the operation mode of the mobile terminal 100 from the normal mode to the evacuation mode when the emergency bulletin is received (step S105). If it is determined by the operation mode switching unit 1043 that the operation mode of the portable terminal 100 is set to the evacuation mode at the time of receiving the emergency bulletin (step S105: Yes), the process of step S114 described later is executed.

  On the other hand, it is assumed that the operation mode switching unit 1043 determines that the setting for maintaining the operation mode of the mobile terminal 100 in the normal mode is made even when the emergency bulletin is received (step S105: No). In this case, the positioning unit 1044 causes the GPS function unit 103 to calculate coordinates indicating the current position of the mobile terminal 100, and acquires the coordinates calculated by the GPS function unit 103, that is, the current position of the mobile terminal 100 (step S106). . However, when the GPS function unit 103 stores the coordinates indicating the current position of the mobile terminal 100 in the cache memory area in the memory 105 constantly or periodically, the positioning means 1044 is the mobile phone that is already stored in the cache memory. The coordinates of the current position of the terminal 100 may be acquired.

  Subsequently, the safety determination unit 1051 determines the safety of the current position of the mobile terminal 100 (step S107). Here, the safety determination unit 1051 refers to the map data, and based on the information indicating the type and scale of the disaster included in the emergency bulletin, is the current position of the mobile terminal 100 safe or dangerous? Determine. For example, it is assumed that the emergency bulletin reports a tsunami warning. In this case, the safety determination unit 1051 determines that the current position is safe when the current position of the mobile terminal 100 is a high ground (for example, a high ground of 50 m or more that is 2 km or more away from the coastline and the river). Further, it is assumed that the emergency warning is to notify an earthquake warning with a seismic intensity of 4. In this case, the safety determination unit 1051 determines that the current position is safe when a building existing around the current position of the mobile terminal 100 has an earthquake resistant structure that can withstand an earthquake having a seismic intensity of 6 or more. .

  Thereafter, the notification unit 1052 generates notification information to be notified to the user via the display unit 107 based on the determination result by the safety determination unit 1051, and stores the notification information in the memory 105 (step S108). Here, for example, it is assumed that the emergency warning is to notify an earthquake warning of seismic intensity 4. Then, it is assumed that the safety determination unit 1051 determines that a building existing around the current position of the mobile terminal 100 has an earthquake-resistant structure that can withstand an earthquake with a seismic intensity of 6 or more and that the current position of the mobile terminal 100 is safe. . In this case, the notification unit 1052 generates notification information indicating a message such as “a building in the vicinity of the building is resistant to seismic intensity 6 and is relatively safe” and stores the notification information in the memory 105.

  Next, the notification unit 1052 acquires the notification information stored in the memory 105 (step S109), and then the notification unit 1052 determines whether or not a preset waiting time has elapsed (step S110). ). The standby time is set to 1 sec, for example. The notification unit 1052 repeats the process of step S110 as long as a preset standby time has not elapsed (step S110: No).

  On the other hand, when the notification unit 1052 determines that a preset standby time has elapsed (step S110: Yes), the notification unit 1052 displays the notification information on the display unit 107 of the mobile terminal 100 (step S111). Here, the notification unit 1052 displays the notification information, for example, superimposed on the character information and icons displayed on the display unit 107.

  Subsequently, the notification unit 1052 determines whether or not a predetermined period has elapsed after the notification information is displayed on the display unit 107 (step S112). The length of the preset period is set to 5 sec to 10 sec, for example. If the notification unit 1052 determines that the preset period has not yet elapsed after displaying the notification information on the display unit 107 (step S112: No), the notification unit 1052 continues to display the notification information (step S111). On the other hand, when the notification unit 1052 determines that a preset period has elapsed after displaying the notification information on the display unit 107 (step S112: Yes), the notification unit 1052 cancels the display of the notification information (step S113). Thereafter, the process of step S101 is executed again.

  Further, in step S105 described above, it is assumed that the operation mode switching unit 1043 determines that the setting of switching the operation mode of the mobile terminal 100 to the evacuation mode is performed when the emergency bulletin is received (step S105: Yes). In this case, the operation mode switching unit 1043 switches the operation mode of the mobile terminal 100 to the evacuation mode (step S114). At this time, the control unit 104 stops the operation of other applications until a cancellation instruction is issued to instruct the user to cancel the evacuation mode.

  Next, the risk range specifying unit 1048 specifies a risk range that is a range that can be covered by a disaster based on information indicating the type and scale of the disaster included in the emergency bulletin (step S115).

  Subsequently, the positioning unit 1044 causes the GPS function unit 103 to calculate coordinates indicating the current position of the mobile terminal 100, and acquires coordinates calculated by the GPS function unit 103, that is, current position information indicating the current position of the mobile terminal 100. Then, the acquired current position information is stored in the memory 105 (step S116). The memory 105 stores position information indicating the position of the mobile terminal 100 obtained by positioning by the positioning unit 1044 in time series.

  Thereafter, the moving direction specifying means 1053 compares the position information of the portable terminal 100 stored in the memory 105 and obtained by the positioning means 1044 immediately before and the current position information indicating the current position of the portable terminal 100. Then, it is determined whether or not the position of the mobile terminal 100 has moved (step S117). If it is determined by the moving direction specifying means 1053 that the position of the mobile terminal 100 has not moved (step S117: No), the process of step S120 described later is executed. Here, when the positioning unit 1044 acquires the current position information of the mobile terminal 100 for the first time after receiving the emergency bulletin, the memory 105 does not store the past position information of the mobile terminal 100. In this case, the moving direction specifying unit 1053 determines that the position of the mobile terminal 100 has not moved.

  On the other hand, when the moving direction specifying unit 1053 determines that the position of the mobile terminal 100 has moved (step S117: Yes), it acquires position information indicating the position of the mobile terminal 100 before the movement from the memory 105 (step S118). . Next, the movement direction identification unit 1053 identifies the movement direction of the portable terminal 100 from the current position of the portable terminal 100 and the position before the portable terminal 100 moves, and generates movement direction information indicating the movement direction of the portable terminal 100. And stored in the memory 105 (step S119).

  Subsequently, as shown in FIG. 3, the safety determination unit 1051 determines the safety of the current position of the mobile terminal 100 in the same manner as in the above-described step S107 (step S120). Thereafter, the notification unit 1052 generates notification information to be notified to the user via the display unit 107 based on the determination result by the safety determination unit 1051 and stores the notification information in the memory 105 in the same manner as in Step S108 described above (Step S108). S121).

  Thereafter, the attribute specifying unit 1045 specifies the attribute requirements that the recommended evacuation site should have based on information indicating the type and scale of the disaster included in the emergency bulletin (step S122). For example, in the case of an emergency earthquake warning, the warning may be a large place such as a park that has a structure that can withstand the expected seismic intensity or a structure that does not collapse. This is an attribute requirement that a suitable recommended evacuation site should have. In the case of a tsunami warning, a building or area located at a much higher height than the expected tsunami height or far away from the coastline and river is a suitable recommended evacuation site for this warning. Attribute requirement.

  Next, as shown in FIG. 3, the recommended evacuation site specifying unit 1046 refers to the map data and satisfies the attribute requirements that are located in the nearest location from the current position of the mobile terminal 100 and should be provided as the recommended evacuation site. A recommended evacuation site is specified (step S123).

  Subsequently, the evacuation route identification unit 1047 identifies the evacuation route to the nearest recommended evacuation site with reference to the map data stored in the memory 105 (step S124).

  Thereafter, the map display means 1042 displays the current position of the mobile terminal 100 and the nearest recommended evacuation site on the map corresponding to the acquired map data, the evacuation route to the recommended evacuation site, the danger range, A screen showing the movement history of the portable terminal 100 is displayed on the display unit 107 (step S125). If there is a nearest recommended evacuation site, the travel route can be displayed only when the user selects one of them, and then the travel history can be displayed, or the evacuation route can be calculated in advance. A plurality of evacuation routes can be automatically displayed. At this time, an icon for operating the map application is also displayed on the screen 107a of the display unit 107 of the mobile terminal 100 at the same time. The map display means 1042 displays a screen 107a as shown in FIG. As shown in FIG. 4, a cancel icon 304, a size adjustment icon 305 for enlarging / reducing a map, and a scale icon 306 are displayed on the screen 107 a. The cancel icon 304 is an icon for canceling the evacuation mode and switching the operation mode to the normal mode for the mobile terminal 100.

  The screen 107a also shows the recommended evacuation site A (501), the current position 500 of the mobile terminal 100, the evacuation route 504 from the current position 500 of the mobile terminal 100 to the recommended evacuation site 501, and the movement history of the mobile terminal 100. 503 are displayed. The movement history 503 of the portable terminal 100 is generated based on the history of the position information of the portable terminal 100 stored in the memory 105 by the map display unit 1042. Further, a danger range mark 601 indicating a danger range is also displayed on the screen 107a. Thereby, the user of the mobile terminal 100 can visually grasp the range that can be dangerous due to a disaster.

  Returning to FIG. 3, next, the icon display means 1054 determines whether or not the positioning means 1044 has acquired the current position information indicating the current position of the mobile terminal 100 a plurality of times after receiving the emergency bulletin (step S126). . If it is determined that the positioning unit 1044 has acquired the current position information indicating the current position of the mobile terminal 100 only once after the emergency prompt is received by the icon display unit 1054 (step S126: No), the process of step S129 described later is performed. Executed.

  On the other hand, if the icon display means 1054 determines that the current position information indicating the current position of the mobile terminal 100 has been acquired a plurality of times by the positioning means 1044 (step S126: Yes), it acquires the movement direction information from the memory 105 ( Step S127).

  Subsequently, the icon display unit 1054 generates a footprint icon indicating the movement direction indicated by the movement direction information and displays the footprint icon on the display unit 107 (step S128). The icon display means 1054 displays the footprint icon 602 along the movement history 503 of the mobile terminal 100, for example, as shown in FIG.

  Here, in order to display the movement route quickly, the footprint icon 602 can be temporarily displayed on the display unit 107 once the current position information indicating the current position is acquired even once. In this case, since the moving direction is not known at that time, when the current position information at the next time is acquired, the straight line connecting the current position information of the two points should be matched with the direction of the toe of the footprint and the heel. Thus, the orientation of the footprint icon 602 is corrected and redisplayed.

  Further, the current position information acquired when the map is not displayed is stored in the buffer memory, and when the map is displayed, these are displayed to obtain continuity of display.

  Furthermore, the orientation of the footprint icon 602 can be corrected every time a new current position acquired over time is acquired, or collectively when a plurality of new position information is obtained. And can be configured to perform the therapy. Correcting the orientation of the footprint icon 602 using a plurality of new current position information does not directly display the variation in the display position and the direction of the footprint icon 602 due to an error in GPS information. Display is possible.

  This display can be applied immediately to one or both of a plurality of new current position information and / or data correction in the buffer memory, and the display position and direction of the movement locus by the footprint icon 602 displayed as a result can be smoothed. can do.

  Thereafter, as shown in FIG. 5, the notification unit 1052 determines whether or not the display of the notification information has been canceled (step S129). If it is determined by the notification unit 1052 that the display of the notification information has already been canceled (step S129: Yes), the process of step S134 described later is executed.

  On the other hand, when the notification unit 1052 determines that the display of the notification information has not yet been canceled (step S129: No), the notification unit 1052 acquires the notification information stored in the memory 105 (step S130), and transmits the notification information to the mobile terminal. 100 is displayed on the display unit 107 (step S131). Here, the notification unit 1052 displays the notification information 301 so as to overlap the map displayed on the display unit 107 as shown in FIG. 4, for example.

  Next, the notification unit 1052 determines whether or not a predetermined period has elapsed after the notification information is displayed on the display unit 107 (step S132). If it is determined that the preset period has not yet elapsed after the notification unit 1052 displays the notification information on the display unit 107 (step S132: No), the process of step S134 described later is executed. On the other hand, when the notification unit 1052 determines that a preset period has elapsed after the notification information is displayed on the display unit 107 (step S132: Yes), the notification unit 1052 cancels the display of the notification information (step S133).

  Thereafter, the map display unit 1042 determines whether or not there has been an evacuation mode cancellation command (step S134). This evacuation mode cancellation command is input to the mobile terminal 100 when the user of the mobile terminal 100 performs an operation for canceling the evacuation mode on the operation unit 108, for example. If it is determined by the map display means 1042 that there has been an evacuation mode release command (step S134: Yes), the process of step S101 is executed again. On the other hand, if the map display means 1042 determines that there is no evacuation mode cancellation command (step S134: No), it executes the process of step S116 again.

  Next, map data update processing executed by the control unit 104 of the mobile terminal 100 according to the present embodiment will be described in detail with reference to FIG. This map data update process is started when the mobile terminal 100 is powered on. Each step shown in the flowchart of FIG. 6 is sequentially processed by the control unit 104 reading and executing a program for updating map data stored in the memory 105. This map data update process is executed in parallel with the portable terminal control process described above. First, the map update means 1049 determines whether or not the update time of the map data stored in the memory 105 has come (step S201). This map data update time is set, for example, every half day. As long as it is determined that the update time of the map data has not arrived (step S201: No), the map update unit 1049 repeatedly executes the process of step S201.

  According to another embodiment, the data update time may be irregular, and the update time may be notified by a push notification from the data distribution server. In the case of such a configuration, it is determined whether or not the map data update time has arrived in the mobile terminal 100 (step S201). Here, as long as it is determined that the push notification from this server has not arrived (step S201: No), the map update unit 1049 repeatedly executes the process of step S201.

  On the other hand, when the map update unit 1049 determines that the update time of the map data has arrived (step S201: Yes), the map update unit 1049 determines whether the operation mode of the mobile terminal 100 is the evacuation mode (step S202). When the map update unit 1049 determines that the operation mode of the mobile terminal 100 is the evacuation mode (step S202: Yes), the map update unit 1049 executes the process of step S201 again.

  On the other hand, when the map update unit 1049 determines that the operation mode of the mobile terminal 100 is the normal mode (step S202: No), the map update unit 1049 connects to the network via the communication circuit 102 and acquires new map data from the outside (step S202). S203). Next, the map update means 1049 updates the map data stored in the memory 105 by storing the newly acquired map data in the memory 105 (step S204). Thereafter, the process of step S201 is executed again.

  As described above, according to the mobile terminal 100 according to the present embodiment, the moving direction specifying unit 1053 determines the mobile terminal from the position of the mobile terminal 100 obtained by positioning in the past and the current position of the mobile terminal 100. 100 moving directions are specified. Then, the icon display unit 1054 generates a footprint icon 602 indicating the moving direction of the mobile terminal 100 based on the moving direction of the mobile terminal 100 specified by the moving direction specifying unit 1053, and the generated footprint icon 602 is converted into map data. Is displayed on the display unit 107 in the form of being overlaid on the map corresponding to. Thereby, whether the user who is evacuating can appropriately move toward the recommended evacuation site by checking the footprint icon 602 displayed on the map corresponding to the map data displayed on the mobile terminal 100. You can check whether or not. Therefore, after a disaster occurs, the user can be appropriately guided to the nearest recommended evacuation site.

  In addition, mobile terminal 100 according to the present embodiment displays footprint icon 602 having a footprint shape on display unit 107. Thereby, there exists an advantage that it becomes easy for a user to recognize the own moving direction visually.

For example, in the embodiment, the example in which the map display unit 1042 uses general map data has been described. However, the present invention is not limited to this example. A configuration using evacuation map data having a smaller data amount than the target map data may be used.

  The map data for evacuation is, for example, data covering an area where an emergency bulletin is transmitted, and does not include information for specifying a general commercial facility. Specifically, the map data for evacuation includes only basic map data and data related to recommended evacuation sites. Since this map data for evacuation does not include information for specifying a general commercial facility or the like, the amount of information relating to the area of the same area is small compared to the general map data. In addition, data on recommended evacuation sites includes information on emergency evacuation sites in the event of a fire transmitted from local governments, information obtained from the original field survey of the creator of evacuation map data, and attributes of each recommended evacuation site Attribute information indicating The basic map data includes data indicating roads adjacent to the recommended evacuation site. The basic map data may not include detailed data regarding roads. In this case, the size of the evacuation map data can be further reduced.

  In the embodiment, the example in which the positioning unit 1044 performs the position of the mobile terminal 100 based on the output from the GPS function unit 103 has been described. However, the present invention is not limited to this, and the positioning means 1044 obtains a relative distance difference from the plurality of base stations to the mobile terminal 100 from the intensity of radio waves received from the plurality of base stations, and uses the triangulation to perform the mobile terminal 100. The position may be detected.

  Moreover, the various functions of the portable terminal 100 according to the present invention can be realized by using a normal computer system without depending on a dedicated system. For example, a program for executing the above operation is stored and distributed to a computer connected to a network on a non-transitory recording medium (for example, CD-ROM: Compact Disc Read only memory) that can be read by the computer system. And you may comprise the portable terminal 100 which performs the above-mentioned process by installing the said program in a computer system.

  Further, the method for providing the program to the computer is arbitrary. For example, the program may be uploaded to a bulletin board system (BBS) of a communication line and distributed to a computer via the communication line. Then, the computer activates this program and executes it like other applications under the control of the OS. Thereby, the computer functions as the portable terminal 100 that executes the above-described processing.

As mentioned above, although each embodiment and modification (including what was written in the description. The same is true hereinafter) of the present invention have been described, the present invention is not limited to these. The present invention includes a combination of the embodiments and modifications as appropriate, and a modification appropriately added thereto.
