Description

  The present invention relates to a mobile terminal, a mobile terminal control method, and a program.

   Large-scale disasters such as the Great East Japan Earthquake and Kumamoto Earthquake have occurred, and disasters such as earthquakes directly below the Tokyo metropolitan area and Nankai Trough, eruptions, tsunamis, or torrential rains are expected. Therefore, how to save a large number of human lives when such a disaster occurs is a major issue.

  In response to these requests, the Disaster Countermeasures Basic Act (hereinafter referred to as the “Law” in this section) amended in June 2013, emergency evacuation sites for escaping from the danger of imminent disasters, and staying for a certain period of time In addition, shelters for ensuring the living environment for evacuees were clearly identified and defined. Designated emergency evacuation site is a facility that meets certain standards such as safety for each type of abnormal phenomenon such as floods and tsunamis as an evacuation site to escape from danger when a disaster occurs or may occur Or it is a place designated by the municipal mayor (Article 49-4 of the Act), and the designated evacuation center has a risk of disaster and allows the evacuated residents to stay for as long as necessary until the danger of the disaster disappears. Or it is a place designated by the mayor as a facility for temporarily staying inhabitants who cannot return home due to a disaster (Article 49-7 of the Act).

  These emergency evacuation sites are distinguished in the order of first moving to designated emergency evacuation sites at the time of a disaster and escaping difficulties such as tsunamis, and then moving to designated evacuation sites if you cannot return home. However, it is said that the designated emergency evacuation site and the designated evacuation site can also be used together (Article 49-8 of the Act).

  However, even if the general public is aware of emergency evacuation sites near their homes or workplaces, they often move to unfamiliar places during travel, business trips, business, etc. I do n’t know. In addition, the nearest emergency evacuation site is not necessarily suitable as an evacuation site at the time of a specific disaster, and there are many cases where a suitable emergency evacuation site and an evacuation route to the emergency evacuation site are not grasped.

  In recent years, with the spread of smartphones, a map application (hereinafter referred to as “app”) that includes a search function that uses a current location detection function such as GPS (Global Positioning System) has been installed. Thus, the current position can be specified, and an emergency evacuation site can be found and a evacuation route can be obtained using a search function by manual operation. However, in a large-scale disaster, the base station or the relay station may be damaged, and as a result, the evacuation route using the communication function of the mobile terminal may not be confirmed.

  Some map apps can obtain evacuation routes even if the map information is downloaded to the mobile terminal in advance and the communication function cannot be used. However, since such existing map data is intended for use during normal times, not at the time of a disaster, addresses, etc. for each point such as general restaurants, shops, leisure facilities, gas stations, tourist spots, etc. Since various types of information such as telephone numbers and service contents are included, the capacity occupied in the internal memory when holding such map data in the portable terminal has become large.

  Therefore, in smartphones with limited capacity, many users are not able to download such map information or keep the data stored only for the area around the point where the app was last used. In some cases, the map may not be available, and some maps may not contain emergency evacuation site information.

  Furthermore, in order to find the evacuation route to the nearest emergency evacuation site in the event of an emergency, the user has to perform several complicated steps such as launching the app, searching for an emergency evacuation site, and instructing the display of the evacuation route. There was a point. Therefore, there has been a problem that it is not easy to obtain an evacuation route in a state where an emergency and a mental panic are likely to occur, such as at the time of a major earthquake or a tsunami.

Even if it is the nearest emergency evacuation site, it may not be appropriate to evacuate to the nearest emergency evacuation site depending on the type of disaster. Table 1 is an excerpt of a list of evacuation sites entitled “Designation of evacuation sites and evacuation roads in the event of an earthquake disaster” issued by the Tokyo Metropolitan Urban Development Bureau in May 2013 (see Non-Patent Document 1). Is. The “Tama River Riverbed / Futako Bridge Area” shown in Table 1 is effective as an emergency evacuation site in the event of a fire. However, when a tsunami occurs, such a place near a river is not suitable as an emergency evacuation site.

  On the other hand, for example, a guidance system configured to obtain limited destination information within a terminal after anticipating a cutoff of communication with a base station has been proposed (see, for example, Patent Document 1).

  In addition, on the Internet, a site that provides a service for presenting a so-called evacuation site map that presents an emergency evacuation site to a user has been established (see Non-Patent Document 2).

JP 2008-192067 A

(Embodiment 1)
Embodiments according to the present invention will be described with reference to the drawings. In addition, this invention is not limited by the following embodiment and drawing.

  FIG. 1 is a block diagram illustrating a configuration example of the mobile terminal 100 according to the present embodiment.

  A portable terminal 100 includes a communication circuit 102, a GPS function unit 103, a control unit 104, a memory (storage means) 105, a power control unit 106, a display unit 107, an operation unit 108, a voice input / output unit 109, and a bus 101 that connects the respective units. With.

  Internal control and data exchange of the portable terminal 100 are executed via the bus 101. The bus 101 includes a control bus and a data bus, and the control of the operation of each unit directly or indirectly connected to the bus 101 and transmission of necessary data are executed via the bus 101.

  The communication circuit 102 transmits / receives data to / from a base station of a mobile phone operator via an antenna (not shown) in the mobile terminal 100, and carries data at a remote place via the bus 101 and the control unit 104. It can be imported into the terminal 100.

  The GPS function unit 103 processes a signal received from a satellite via an antenna (not shown) arranged in the mobile terminal 100 and calculates coordinates indicating the current position of the mobile terminal 100 on the ground.

  The memory 105 may be used in an operation system used by the control unit 104, a program such as a map application (hereinafter referred to as “app”) or an evacuation mode application, and a portable terminal such as an e-mail, an address book, and user information. Store some data. The memory 105 stores general map data and evacuation map data.

  General map data includes basic map data such as roads, sidewalks, and passages placed on the ground, and restaurants, commercial facilities, stations, buildings, government offices, sightseeing spots, emergency evacuations displayed on the map indicated by the basic map data. Includes both additional information about the location, etc. 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 data indicating an address code, a block code, an address, a house number, a name, and the like.

  The evacuation map data is data that specifies an emergency evacuation site, and is data that covers the whole of Japan where an emergency bulletin is transmitted from a telecommunications carrier. And unlike the general map data, the evacuation map data does not include information for specifying a general commercial facility or the like. The evacuation map data includes basic map data and data indicating an emergency evacuation site. The evacuation map data has a small capacity compared to the map information capacity when displaying a map of an area of the same area because it does not include the attached information on the restaurant, the commercial facility and the like. In addition, the evacuation map data includes information on emergency evacuation sites in the event of a fire sent by local governments, information based on original field surveys, and specific emergency evacuation sites set for each emergency evacuation site. Contains attribute parameters.

  Further, the evacuation map data includes at least data indicating an emergency evacuation place and data indicating a road adjacent thereto. However, in order to further reduce the storage capacity required for the memory 105, the basic map data may not include coloring, detailed data on roads, information indicating road widths, and the like.

  The control unit 104 includes a microprocessor, and executes main processes in the portable terminal 100 by reading and executing programs stored in the control unit 104 and the memory 105. The control unit 104 functions as an emergency early warning receiving unit 1041, a map display unit 1042, an operation mode switching unit 1043, and a setting unit 1044. The emergency bulletin receiving unit 1041 receives the emergency bulletin via the communication line connected by the communication circuit 102. The operation mode switching unit 1043 receives the emergency bulletin from the mobile terminal 100 when the emergency bulletin receiving unit 1041 receives the emergency bulletin. Switch to evacuation mode that displays at least the nearest emergency evacuation site. The setting unit 1044 sets whether or not the operation mode switching unit 1043 switches the operation mode of the mobile terminal 100 to the evacuation mode. The attribute specifying unit 1045 specifies attribute requirements that the emergency evacuation site should have in accordance with the emergency bulletin. The preferred emergency evacuation site specifying means 1046 is the attribute requirement that is located in the nearest location from the current position among the emergency evacuation sites from the current position of the mobile terminal 100 specified by the GPS function unit 103 and the attribute specifying unit 1045 specifies. Identify suitable emergency evacuation sites that have been met. The map display unit 1042 displays the emergency evacuation site specified by the evacuation map data, and causes the display unit 107 to display the evacuation route to the suitable emergency evacuation site specified by the suitable emergency evacuation site specifying unit 1046.

  The control unit 104 can detect the current position of the mobile terminal 100 based on the output from the GPS function unit 103, but the communication circuit 102 such as triangulation based on the distance difference from a plurality of base stations or other input circuit It is also possible to detect the current position based on the output from.

  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 evacuation map data for displaying the evacuation route 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 mobile terminal 100, and is generally configured by a pressure-sensitive sensor and a push button.

  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 LCI 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.

  When the mobile terminal 100 is performing a normal operation, when the user selects one of the icons of a plurality of applications displayed on the display unit 107, the control unit 104 activates a specific application stored in the memory 105. When the user performs a necessary operation on the operation unit 108, the control unit 104 executes a program corresponding to a specific application stored in the memory 105.

  The map application stored in the memory 105 is for displaying the current position and the route to the destination. The destination is selected by the user inputting the name and attributes of the destination (for example, station, post office, emergency 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 communication circuit 102 is configured to receive an emergency bulletin transmitted from a base station of a mobile phone operator and to execute processing according to the received emergency bulletin in the display unit 107, the voice input / output unit 109, and the control unit 104. Has been.

  The emergency bulletin is information including “emergency earthquake bulletin”, “tsunami warning”, “special warning” distributed by the Japan Meteorological Agency and the like, “disaster / evacuation information” distributed by the national / local public bodies, and the like. 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. Also, the mobile phone operator or other service provider can change the emergency bulletin that can be received by the mobile terminal 100 or add additional information.

  The emergency bulletin in this specification is based on the use of a service that simultaneously distributes messages to a mobile terminal 100 (such as a telephone or a smartphone) in a specific area in a manner that is less susceptible to congestion, and a normal e-mail service. Any or both of those used. In addition, emergency bulletins include special warnings that are issued when heavy rain, storms, storm surges, waves, storm snow, and heavy snow that are expected to occur once every several decades, and serious damage to the residential area. And / or “special warning regarding eruption” that is announced when an eruption occurs or is expected.

  When an earthquake, tsunami, and “special warnings related to weather, etc.” and “special warnings related to eruptions” are announced, the Japan Meteorological Agency automatically sends emergency earthquake warnings, tsunami warnings, and special warnings to mobile phone operators. Mobile phone operators are broadcasting emergency bulletins all over the target area. In addition, highly urgent information related to disasters, such as evacuation advisories and evacuation instructions accompanying disasters, is created as disaster / evacuation information from the national or local government and distributed to the target areas in the same way via mobile phone operators. The

  The memory 105 stores the evacuation mode application. The evacuation mode application switches the operation mode of the mobile terminal 100 to the evacuation mode when the emergency bulletin is received. The evacuation mode application activates the map application and displays the evacuation route from the current position of the mobile terminal 100 specified by the GPS function unit 103 to the nearest evacuation site.

  The evacuation mode application is automatically activated when the power of the mobile terminal 100 is turned on, and an operation for activating the evacuation mode application by the user is unnecessary. Note that the evacuation mode application may be configured to start only when the user performs an operation for starting the evacuation mode application on the mobile terminal 100. Furthermore, this evacuation mode application can also select whether or not to activate the evacuation mode depending on the content of the received emergency bulletin.

  Depending on the contents of the emergency bulletin, the selection of the evacuation mode activation is set according to the type and degree of disaster included in the emergency bulletin. For example, taking a tsunami warning as an example, there are three types: a large tsunami warning, a tsunami warning, and a tsunami warning. Of these, a large tsunami warning and a tsunami warning are targeted for emergency warning. In addition, if there is a numerical announcement in the Great Tsunami Warning, it will be announced in three stages, more than 10 meters, 5 to 10 meters, and 3 to 5 meters.

  For this reason, the evacuation mode is activated in the case of a large tsunami warning, for example, in the case of a large tsunami warning, but in the case of a tsunami warning, the evacuation mode should not be activated. Is possible. However, since the presence or absence of activation of the evacuation mode is irrelevant to the presence or absence of the display of the emergency bulletin, the emergency bulletin is always displayed by the portable terminal 100.

  When the mobile terminal 100 receives the emergency bulletin via the communication line connected to the communication circuit 102, the mobile terminal 100 operates in the evacuation mode, and evacuates from the nearest emergency evacuation site and the current location of the mobile terminal 100 to the emergency evacuation site. The route is displayed together with the emergency bulletin (not shown).

  Here, it is configured such that whether or not to operate the evacuation mode is determined according to the breaking news category such as earthquake, tsunami, and heavy rain included in the emergency breaking news and the severity (for example, seismic intensity 5 or more in the case of an earthquake). It is also possible to configure as described above.

  In addition, when the user performs an operation for stopping the operation in the evacuation mode with respect to the mobile terminal 100 when the user operates the evacuation mode after the mobile terminal 100 is activated, the evacuation mode application Is released.

  Whether or not the mobile terminal 100 operates in the evacuation mode can be set 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 emergency 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 in a safe high-rise building based on an earthquake-resistant design, it may be preferable to stay there rather than immediately heading to a shelter for an emergency early warning of a major earthquake.

  Hereinafter, the operation of the mobile terminal 100 according to the embodiment will be described with reference to FIG.

  FIG. 2 is a flowchart for explaining an example of the operation of the control unit 104 of the mobile terminal 100 according to the present embodiment. Each step shown in this flowchart is sequentially processed by the control unit 104 executing a program stored in the memory 105.

  First, when the mobile terminal 100 is activated, the control unit 104 determines whether or not an emergency bulletin has been received (step S201).

  If the control unit 104 determines that the emergency bulletin has not been received (step S201: No), the normal processing is continued (step S202). 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 S201 is executed.

  On the other hand, when determining that the emergency bulletin has been received (step S201: Yes), the control unit 104 switches the operation mode of the mobile terminal 100 to the evacuation mode (step S203). 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 control unit 104 acquires the current position of the mobile terminal 100 specified by the GPS function unit 103 (step S204). Of course, when the GPS function unit 103 constantly or periodically updates the current position, the current position already acquired in the cache memory or the like can be used.

  Next, the control unit 104 identifies a suitable emergency evacuation site that is located in the nearest location from the current position of the mobile terminal 100 acquired by referring to the location data of the emergency evacuation site and that satisfies a preferable attribute as an evacuation site. (Step S205).

  Here, “nearest” does not necessarily mean an emergency evacuation site with the shortest straight line distance from the current position of the mobile terminal 100, but an emergency route with the shortest arrival route from the current position of the mobile terminal 100. It may mean an evacuation site. In addition, the term “nearest” is not limited to one emergency evacuation site, but single or plural (for example, two to three) according to the default setting at the time of shipping the mobile terminal 100 in advance or the setting by the user thereafter. It may be an emergency evacuation site.

  Note that the process of identifying the preferred emergency evacuation site (step S205) in the present embodiment will be described using an example of identifying the nearest emergency evacuation site based on the map data stored in the memory 105 in the mobile terminal 100. However, when the emergency evacuation site data included in the latest map data is used, it can be performed after the step of selecting map data (step S207 or step S208) described later.

  Here, the preferred emergency evacuation site specifying process for specifying the preferred emergency evacuation site will be described in detail with reference to FIG.

  First, the control unit 104 decodes the contents of the emergency bulletin received by the emergency bulletin receiving unit 1041 (step S2051). 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.

  Next, the control unit 104 identifies attribute requirements that the emergency evacuation site should have according to the content of the acquired emergency bulletin (step S2052).

  For example, it is assumed that the emergency warning is a tsunami warning for notifying the arrival of a tsunami. In this case, evacuation to an emergency evacuation site facing the sea or river or to an emergency evacuation site with a low sea level is inappropriate. Therefore, the control unit 104 is at an upper floor that is at least considerably higher than the height at which the assumed tsunami reaches or is higher than the height at which the assumed tsunami of a building that can withstand the tsunami reaches, A place where emergency evacuation can be performed is identified as an attribute requirement that the emergency evacuation place should have.

  In addition, it is assumed that the emergency early warning is a torrential rain alarm that notifies that there is a high risk of landslides due to torrential rain. In this case, the control unit 104 specifies a place that is not located under the cliff as an attribute requirement that the emergency evacuation place should have. In addition, the control part 104 specifies the attribute requirements according to each of multiple types of alarm, when an emergency early warning is what alert | reports simultaneously multiple types of alarms (for example, a heavy rain alarm and a storm surge warning).

  Subsequently, the control unit 104 acquires the evacuation map data from the memory 105 and specifies the nearest emergency evacuation site by calculating the distance between each emergency evacuation site indicated by the evacuation map data and the current position (step S2053). For example, the evacuation map data is composed of numerical values or characters representing combinations of nodes that are road network intersections and other road network node points and links that indicate road sections connecting the nodes. Suppose it is a group. In this case, the control unit 104 calculates the relative distance or the reach distance between the current position and each emergency evacuation site using the node number assigned to each node and link and information indicating the link number. . And the control part 104 makes several emergency evacuation places selected in an order from the shortest calculated relative distance or arrival distance as the nearest emergency evacuation place.

  Thereafter, the control unit 104 sets attribute information of the nearest emergency evacuation site (step S2054). Here, the control unit 104 determines the attribute requirements of each emergency evacuation site, information on the emergency evacuation site at the time of a fire transmitted from a local government, included in the evacuation map data, information based on an original field survey, and each Based on the specific attribute parameter set for the emergency evacuation site.

For example, the control unit 104 sets attribute information including flags for each of four attribute requirements as shown in Table 2 for the nearest evacuation site.

  Here, when the attribute requirement is satisfied, the flag is set to “1”, and when the attribute requirement is not satisfied, the flag is set to “0”. In the example of Table 2, the attribute information of each emergency evacuation site is composed of 4-bit data composed of 1-bit flags for each of the four types of attribute requirements.

  In the example shown in Table 2, the emergency evacuation site X satisfies all four attribute requirements. The emergency evacuation site Y is a suitable emergency evacuation site when the emergency bulletin reports “tsunami warning” or “storm surge warning”, but indicates an inappropriate emergency evacuation site in other cases ing. Emergency evacuation site Z is an emergency evacuation site that is suitable when the emergency bulletin alerts a “concentrated heavy rain warning” or “large-scale fire alarm”, but is an inappropriate emergency evacuation site in other cases It is shown that.

  Next, the control unit 104 determines whether or not the attribute information of the nearest emergency evacuation site satisfies the attribute requirements that the specified emergency evacuation site should have (step S2055).

  Assume that the control unit 104 determines that the attribute information of the nearest emergency evacuation site does not satisfy the attribute requirements that the identified emergency evacuation site should have (step S2055: No). In this case, the control unit 104 determines whether there is another emergency evacuation site that has not yet been determined (step S2056).

  If the control unit 104 determines that there is another emergency evacuation site that has not yet been determined (step S2055: Yes), the nearest emergency evacuation site other than the emergency evacuation site that is the determination target is selected. An evacuation place is specified (step S2053). Thereafter, the processing after step S2054 is executed.

  On the other hand, when determining that there is no other emergency evacuation site that has not yet been determined (step S2056: No), the control unit 104 notifies an alarm (step S2057).

  If the control unit 104 determines that the nearest emergency evacuation site satisfies the specified attribute requirement (step S2055: Yes), the control unit 104 identifies the nearest emergency evacuation site as a suitable emergency evacuation site (step S2058). Thereafter, processing for determining whether or not the communication line shown in step S206 in FIG. 2 is disconnected is executed.

  If the emergency bulletin alerts a tsunami warning, the emergency evacuation site is at least at a height that is considerably higher than the expected tsunami reach, or the expected tsunami of a building that can withstand the tsunami arrives It must be located on an upper floor that is higher than the height you want to evacuate. In this case, when the attribute information of each emergency evacuation site is set as shown in Table 2, the control unit 104 sets the attribute information MSB to “1”, that is, the attribute information starts from “8” in hexadecimal notation. The emergency evacuation sites X and Y indicating a value between “F” are specified as preferred emergency evacuation sites.

  In addition, if the emergency bulletin alerts a torrential rain alert that a severe torrential rain will occur, the emergency evacuation site should be located at least at the riverbed where flooding is expected or on the cliff where there is a risk of landslides. Don't be. In this case, when the attribute information of each emergency evacuation site is set as shown in Table 2, the control unit 104 selects the emergency evacuation sites X and Z whose third bit from the LSB of the attribute information is “1” as the preferred emergency Identify as evacuation site.

  In addition, if the emergency bulletin alerts a large-scale fire warning that a large-scale fire has occurred, the emergency evacuation site is safe for those who have evacuated there even if the fire spreads around it. It must be large enough to be secured, or be a facility that can handle such situations. In this case, when the attribute information of each emergency evacuation site is set as shown in Table 2, the control unit 104 selects the emergency evacuation sites X and Z whose second bit from the LSB of the attribute information is “1” as the preferred emergency Identify as evacuation site.

  Also, if the emergency bulletin alerts a storm surge warning, the emergency evacuation site is at least at a location that is considerably higher than the expected inundation due to the assumed storm surge, or from the location where the assumed storm surge arrives, It must be located at a considerable distance. However, the urgency is low compared to the tsunami because it is periodic at high tide and is expected in a certain temporal and regional range when storm surges occur. In this case, when the attribute information of each emergency evacuation site is set as shown in Table 2, the control unit 104 identifies emergency evacuation sites X and Y whose attribute information LSB is “1” as preferred emergency evacuation sites. .

  In this embodiment, the example in which the control unit 104 executes the process of step S2055 has been described. However, the process of step S2055 is executed by, for example, a comparison circuit (comparator) included in an integrated circuit. Also good.

  In addition, when there is no attribute requirement that the emergency evacuation site should have, the control unit 104 identifies any suitable emergency evacuation site as long as the value indicated by the attribute information is an emergency evacuation site that is “0” or more in hexadecimal. It will be. In this case, any nearest emergency evacuation site is not excluded from suitable emergency evacuation site candidates by the attribute information of the emergency evacuation site.

  As described above, the control unit 104 executes a series of processes from step S2051 to S2058 to identify a suitable emergency evacuation site that is the nearest emergency evacuation site suitable for evacuation, and then performs step S206 in FIG. Execute the process.

  Subsequently, before starting the map application, the control unit 104 determines whether or not the communication line for acquiring additional data is disconnected (step S206).

  If the control unit 104 determines that the communication line is disconnected due to a collapse of a neighboring base station or the like (step S206: Yes), the control unit 104 selects map data stored in advance in the memory 105 of the mobile terminal 100 (step S207). On the other hand, when determining that the communication line can be used normally (step S206: No), the control unit 104 downloads the map data to the portable terminal 100 and selects the downloaded map data (step S208).

  Note that the map data stored in the memory 105 may be map data used in normal processing. However, the map data used in the normal processing may be limited to those around the current position when the map application is last used, and information at the time of receiving the emergency bulletin is held in the mobile terminal 100. It may not be. In addition, when the map data used in normal processing is map data in a range covering the whole of Japan, a considerable amount of memory capacity is consumed when the map data is always stored in the mobile terminal 100. Therefore, when the maximum capacity of the memory 105 of the portable terminal 100 is small, the entire map data cannot be stored in the memory 105.

  Further, the map data used when the mobile terminal 100 operates in the evacuation mode can make the user recognize the emergency evacuation site and the evacuation route from the current position to the emergency evacuation site. It is enough that the information is included. Further, the map data used when the mobile terminal 100 operates in the evacuation mode may not include data relating to general commercial facilities and the like as the map data used for normal processing. Therefore, it is preferable that the map data used when the mobile terminal 100 operates in the evacuation mode is relatively small-capacity map data that does not include data related to general commercial facilities.

  In addition, the advantage that the map data used when the mobile terminal 100 operates in the evacuation mode is the map data in a range that covers the whole of Japan, for example, a user who usually lives only in the vicinity of Tokyo, When you receive emergency bulletins when you visit Hokkaido or Okinawa, you can display emergency evacuation sites without downloading new map data.

  In order to reduce the capacity of the memory 105, it is also useful to simplify the map data used when the mobile terminal 100 operates in the evacuation mode compared to the map data specified in the normal processing. . The map data used when the mobile terminal 100 operates in the evacuation mode includes, for example, only map data from which information on color is deleted, and information on a required road (however, a road that touches an evacuation site is regarded as a required road). You may be comprised from the map data or the map data which handled all the road widths as fixed.

  Further, the memory 105 may store map data including only the data of the emergency evacuation site and the data of the evacuation route to the emergency evacuation site. And the control part 104 may be comprised so that the data regarding a general commercial facility etc. may be downloaded via a communication line and it may add to the map data which the memory 105 memorize | stores in a normal process. Thereby, the control unit 104 can use the same map data in the normal processing and the operation in the evacuation mode.

  Then, the control unit 104 selects either the map data stored in the memory 105 or the downloaded map data, and then from the emergency evacuation site and the current position of the mobile terminal 100 to the selected nearest emergency evacuation site. The evacuation route is displayed on the display unit 107 (step S209).

  FIG. 4 shows an example of a display screen 107 that displays one evacuation route 303 to one emergency evacuation site 302 according to the present embodiment.

  An evacuation route 303 from the current position 301 acquired using the GPS function of the mobile terminal 100 to the evacuation site 302 is displayed by the map application. For the sake of simplicity, other roads, terrain, buildings, etc. are not displayed in this figure, but it is needless to say that a map to the extent necessary for evacuation guidance should be displayed at the same time (hereinafter referred to as other It is the same in the figure of).

  The display unit 107 also displays an icon for operating the map application. In the example shown in FIG. 4, a cancel icon 304, a size adjustment icon 305 for enlarging / reducing the map, a scale icon 306, and a selection icon 307 are displayed. The cancel icon 304 is an icon for canceling the evacuation mode in which the evacuation route 303 to the emergency evacuation site 302 is displayed on the display unit 107.

  The display unit 107 and the operation unit 108 according to the present embodiment are digitizers arranged in a stacked manner on the surface of the mobile terminal 100, and a desired operation is executed by pressing an appropriate icon.

  The length and display unit of the scale icon 306 change according to the enlargement or reduction of the image displayed on the display unit 107.

  The vertical and horizontal movements of the screen can be automatically moved so that the current position 301 is the center, and the scale and arrangement are automatically adjusted so that the current position 301 and the evacuation site 302 are always displayed. It may be. It is also possible to configure the map to move in a direction in which the user presses and holds a specific point with a finger and slides the finger.

  Returning to FIG. 2, the control unit 104 determines whether or not a cancellation command has been issued to cancel the evacuation mode by the user (step S <b> 210). This release command is made when the user touches the release icon 304 displayed on the display unit 107. When determining that the release command has not been issued (step S210: No), the control unit 104 executes again the process of step S206 for determining whether or not the communication line is disconnected. This is because the state of the communication line with the base station changes depending on the location where the user has moved, or the base station that was available at the beginning of the disaster can no longer be used.

  The control unit 104 continues to display the evacuation route on the display unit 107 while repeatedly updating the current position of the mobile terminal 100 using the GPS function of the mobile terminal 100 by repeating the processing from step S206 to step S210.

  On the other hand, when a cancellation command is issued by the user (step S210: Yes), the control unit 104 ends the series of evacuation modes and returns to the process of step S201 for determining whether or not a new emergency bulletin has been received. At this time, the control unit 104 restores the operation of the other application that has been stopped.

  In the description with reference to FIG. 2, the description has been given of the configuration in which either the map data stored in the memory 105 or the downloaded map data is selected and the evacuation route is displayed. It is also possible to select only one of the map data to be downloaded and the downloaded map data and display the evacuation route.

  That is, when the portable terminal 100 is operating in the evacuation mode, the control unit 104 may use only the map data stored in the memory 105 and may not use the communication line at all. Alternatively, when the mobile terminal 100 is operating in the evacuation mode, the control unit 104 may use only downloaded map data.

  However, since the communication line may be interrupted immediately after receiving the emergency bulletin, map data used when the mobile terminal 100 operates in the evacuation mode is stored in the memory 105 of the mobile terminal 100 in advance. Is preferable from the aspect of crisis management.

  The map data stored in the memory 105 is preinstalled when the mobile terminal 100 is shipped, downloaded after the mobile terminal 100 is shipped, or updated sequentially when the mobile terminal 100 is used.

(Embodiment 2)
The mobile terminal 100 according to the present embodiment has a function of displaying on the display unit 107 when there are a plurality of emergency evacuation sites or when there are a plurality of evacuation routes.

  The display of the evacuation route shown in FIG. 4 of the first embodiment displays only one nearest emergency evacuation site, but in some cases, a plurality of emergency evacuation sites and / or a plurality of evacuation routes are displayed. In some cases, it is preferable that the user can select an evacuation route to be used by himself / herself.

  For example, when a bridge in the middle of a specific route collapses, or when a large obstacle is created on the road, a specific evacuation site or route cannot be used due to a fire. In such a case, the portable terminal 100 according to the present embodiment is more advantageous than that according to the first embodiment. The configuration of portable terminal 100 according to the present embodiment is the same as the configuration shown in FIG.

  5 and 6 are flowcharts showing an example of the operation of the mobile terminal 100 according to the present embodiment. In FIG. 5 and FIG. 6, the same reference numerals are assigned to the same processes as those in the first embodiment.

  As shown in FIG. 5, the control unit 104 determines whether or not there is a plurality of emergency evacuation site display commands for instructing to display a plurality of emergency evacuation sites after executing a series of processes from steps S201 to S205. Determination is made (step S401). When determining that there is no multiple emergency evacuation site display command (step S401: No), the control unit 104 selects one nearest emergency evacuation site according to a predetermined condition (step S402). On the other hand, when determining that there is a plurality of emergency evacuation site display instructions (step S401: Yes), the control unit 104 selects a plurality of emergency evacuation sites (step S403).

  Next, the control unit 104 executes a series of processes from steps S206 to S208. Subsequently, the control unit 104 causes the display unit 107 to display one or more emergency evacuation sites (step S404).

  Thereafter, the control unit 104 determines whether there is a command to display a plurality of evacuation routes for each emergency evacuation site (step S405). When it is determined that there is no instruction to display a plurality of evacuation routes (step S405: No), the control unit 104 selects one evacuation route according to a predetermined condition (step S406). On the other hand, when determining that there is a command to display a plurality of evacuation routes (step S405: Yes), the control unit 104 selects a predetermined number of evacuation routes (step S407).

  Next, the control unit 104 causes the display unit 107 to display one or more evacuation routes in a form of additionally displaying one or more emergency evacuation sites (step S408). Thereafter, the processing after step S210 is executed.

  In the above description, an example in which the control unit 104 selects a plurality of emergency evacuation sites or one emergency evacuation site depending on whether or not a command to display a plurality of emergency evacuation sites has been given in advance in the process of step S401. However, the processing content of step S401 is not limited to this. For example, instead of the process of step S401, the control unit 104 displays whether or not to display a plurality of emergency evacuation sites and options for the display on the display unit 107, and allows a plurality of emergency evacuation sites or one An emergency evacuation site may be selected. Specifically, for example, when the control unit 104 displays a character string “Display multiple evacuation sites?” On the display unit 107 and the user touches the release icon 304 or the selection icon 307, the control unit 104 responds accordingly. What is necessary is just to make it process. The same applies to the determination of whether to display a plurality of evacuation routes or one evacuation route for each emergency evacuation site in step S405.

  In addition, when the user displays one emergency evacuation place or one evacuation route on the display unit 107, the control unit 104 determines that the one emergency evacuation place or one evacuation route cannot be used. It is preferable that the emergency evacuation place or evacuation route can be set to be displayed on the display unit 107.

  Furthermore, in the present embodiment, the control unit 104 first displays the emergency evacuation place in the process of step S404 and then additionally displays the evacuation route in the process of step S408. However, the present invention is not limited to this. The control unit 104 may collectively display the emergency evacuation site information and the evacuation route information on the display unit 107. In particular, when preset so that the number of evacuation sites or the number of evacuation routes selected by the user is not changed, the evacuation sites and evacuation routes displayed on the display unit 107 are displayed substantially simultaneously. Become.

  FIG. 7 shows an example of a display screen that displays one evacuation route to a plurality of emergency evacuation sites according to the present embodiment.

  As shown in FIG. 7, emergency evacuation sites A, B, and C (501, 502, 503) and evacuation routes 504, 505, 506 from the current position 500 to each emergency evacuation site 501, 502, 503 are displayed on the display unit 107. It is displayed.

  FIG. 8 shows an example of a display screen that displays a plurality of evacuation routes according to the present embodiment.

  As shown in FIG. 8, a plurality of evacuation routes 602, 603, 604 from the current position 600 to the emergency evacuation site 601 are displayed on the display unit 107.

  Here, a modification of the display mode when the current position of the mobile terminal 100 moves from the position 600 to the position 605 will be described below.

  FIG. 9 shows an example of a display screen that displays a plurality of evacuation routes 603 and 607 to one emergency evacuation place 601 after the current position of the mobile terminal 100 moves from the position 600 to the position 605. . In FIG. 9, the same reference numerals as those in FIG. 8 are assigned to the same emergency evacuation sites and evacuation routes shown in FIG. An evacuation route 607 indicates an evacuation route after the current position 605 of the mobile terminal 100 in the evacuation route 602.

  As shown in FIG. 9, when the current position of the mobile terminal 100 is the position 605, the evacuation route 604 displayed on the display unit 107 when the current position is the position 600 is not displayed (although illustrated. The map information that has not been made remains as the background, and the same applies to FIG.

  By doing so, as the user approaches the emergency evacuation site 601, it is not necessary to see unnecessary information while recognizing evacuation route options.

  A technique used in a normal map application, such as displaying on the display unit 107 so that the traveling direction of the user holding the mobile terminal 100 is on the upper side of the display unit 107 is applied to the present embodiment. Also good.

  In the present embodiment, when the current position of the mobile terminal 100 moves from the position 600 to the position 605, only the evacuation route after the current position 605 of the mobile terminal 100 is displayed on the display unit 107 as shown in FIG. An example was described. However, the present invention is not limited to this. For example, as shown in FIG. 10, when the current position of the mobile terminal 100 moves from the position 600 to the position 605, from the evacuation route 604 and the position 600 when the current position is the position 600. The route followed by the mobile terminal 100 up to the current position 605 may be displayed on the display unit 107 with a broken line.

  In this way, the user can always recognize the evacuation route options as he approaches the emergency evacuation site 601. For example, when a user is moving on the evacuation route 602 and an inconvenience such as breakage of the evacuation route 602 is found, the user can return to the original position 600 and select the evacuation route 604. .

  Further, even when the control unit 104 specifies only three evacuation routes 602, 603, and 604 when the current position of the mobile terminal 100 is the position 600, the control unit 104 moves to the position 605. In some cases, a new evacuation route from the new current position 605 to the emergency evacuation site 601 may be specified. In this case, for example, as shown in FIG. 10, the current position of the mobile terminal 100 is added to the evacuation routes 602, 603, and 604 specified when the position 600 is reached, and the emergency evacuation site 601 is reached from the new current position 605. A new evacuation route 801 may be displayed on the display unit 107.

  Of the plurality of processes described with reference to FIG. 2 or FIG. 5 and FIG. 6, the selection of the process to be assigned to the evacuation mode application is a design matter. For example, in the process described with reference to FIG. 2, the basic OS software may be in charge of the processes in steps S201, S202, and S210, and the evacuation mode application may be in charge of the processes in steps S203 to S209. Alternatively, the evacuation mode application may be in charge of all the processing described in FIG. Among the processes described with reference to FIG. 2, various modifications can be made to the process handled by the evacuation mode application.

  What is important is that all or part of each step shown in FIG. 2 is embedded in software included in the mobile terminal 100, and the operation mode of the mobile terminal 100 is switched to the evacuation mode.

  In each embodiment, the example in which the current position detection function is realized by the GPS function unit 103 in the mobile terminal 100 has been described. However, if the current position of the mobile terminal 100 can be specified with a certain degree of accuracy, this is used. It is not limited.

  Moreover, although each embodiment demonstrated the example which displays an emergency evacuation place and an evacuation route on the display part 107 of the portable terminal 100, it is not limited to this, For example, an evacuation route is notified to a user with an audio | voice It may be configured to. In this case, for example, the memory 105 stores voice information instructing the traveling direction in advance, and the control unit 104 appropriately selects the voice information from the memory 105 based on the current position of the mobile terminal 100 and the evacuation map data, and the voice What is necessary is just to make it output to the input-output part 109. FIG.

  Furthermore, although the evacuation map data in each of the above embodiments has been described as including emergency evacuation sites located throughout Japan where emergency bulletins are transmitted from communication carriers, when the present invention is implemented overseas Of course, it should be within the range that can be reached by the urgent news of telecommunications carriers in that country, and as long as the amount of information stored in the mobile terminal 100 allows, data on emergency evacuation sites in multiple countries or around the world can be used. It can also be included.

  In addition, in each of the embodiments described above, the evacuation map data has been described as being separated from the general map data, but this is intended to reduce the constantly stored data in the mobile terminal 100, but the emergency It can also be integrated into general map data including evacuation sites.

  Furthermore, although the setting as to whether or not the control means according to the present invention activates the evacuation mode is determined in advance, it is also possible to set the evacuation mode to be activated at all times when an emergency early warning is received.

  Furthermore, the control unit 104 is illustrated as an example of stopping the operation of other applications until a cancellation instruction for instructing the user to cancel the evacuation mode is given. This is because the evacuation route to the emergency evacuation site is displayed even if it is lowered. Depending on the remaining battery level, it is possible to determine whether this operation is to be performed or not, or not to perform this power saving operation itself.
