  Hereinafter, a guide device according to an embodiment of the present invention will be described. A guide device according to an embodiment of the present invention is any one of a first operation mode and a second operation mode in which some of the functions of the first operation mode are limited. An operation control unit that operates in a mode and a receiving unit that receives emergency information are provided. Then, the operation control unit switches from the first operation mode to the second operation mode when the reception unit receives the emergency information. In this way, when emergency information is received, it is possible to limit only operations related to emergency information. Therefore, for example, when emergency information related to an earthquake or tsunami is received, guidance suitable for the situation, such as guidance to an evacuation site, can be restricted by restricting guidance to a sightseeing spot.

  Moreover, you may further provide the present position acquisition part which acquires the information regarding a present position, and the display part which displays the guidance information which guides a user. By doing so, it is possible to display guidance information such as a route from the current position to the destination, information on tourist facilities, and information on facilities related to emergency information.

  The display unit displays facility guidance information regarding the facility when the current location acquired by the current location acquisition unit approaches within a predetermined range from the predetermined facility, and the operation control unit displays the second operation mode. When the operation is performed, the facility guidance information may be restricted from being displayed on the display unit when the current position approaches a predetermined range from the facility. In this way, in the first mode, it is possible to display only guidance information on facilities related to emergency information without displaying facility guidance information such as tourist guidance that can be displayed.

  In addition, the display unit displays a search result searched for facilities existing within a predetermined range from the current position acquired by the current position acquisition unit, and when the operation control unit operates in the second operation mode, A facility other than the facility related to the emergency information may be displayed on the display unit without being included in the search result. In this way, it is possible to display only the facilities that are desired to be displayed when receiving emergency information such as an evacuation site. Therefore, the evacuation site can be easily searched, and the display of the evacuation site and the route search can be easily performed.

  In addition, the guidance method according to the embodiment of the present invention includes any one of the first operation mode and the second operation mode in which some of the functions of the first operation mode are limited. And an operation control step for operating in any mode and a reception step for receiving emergency information. Then, the operation control step switches from the first operation mode to the second operation mode when the emergency information is received in the reception step. In this way, when emergency information is received, it is possible to limit only operations related to emergency information. Therefore, for example, when emergency information related to an earthquake or tsunami is received, guidance suitable for the situation, such as guidance to an evacuation site, can be restricted by restricting guidance to a sightseeing spot.

  Moreover, it is good also as a guidance program which performs the guidance method mentioned above by computer. In this way, when emergency information is received using a computer, it is possible to limit only operations related to emergency information. Therefore, for example, when emergency information related to an earthquake or tsunami is received, guidance suitable for the situation, such as guidance to an evacuation site, can be restricted by restricting guidance to a sightseeing spot.

  Further, the above-described guidance program may be stored in a computer-readable recording medium. In this way, the program can be distributed as a single unit in addition to being incorporated in the device, and version upgrades can be easily performed.

  A guide device according to an embodiment of the present invention will be described with reference to FIGS. A navigation device 50 as a guide device according to an embodiment of the present invention is arranged on a moving body and searches and guides a route from a predetermined position such as a current location to a destination. In the present embodiment, a bicycle is described as an example of the moving body, but other moving bodies such as an automobile, a motorcycle, and a pedestrian may be used. In short, the mobile body is not particularly limited as long as it is a device that guides the movement of the user.

  As shown in FIG. 1, the navigation device 50 can communicate with the server 100 via a network 101 such as a public network or the Internet. Note that the navigation device 50 and the network 101 communicate wirelessly via a base station, an access point, etc. (not shown).

Further, if necessary, a route to a predetermined position such as a destination input from the operation unit 55, a traveling direction, and the like are generated.

  The control unit 51 includes an operation control unit 51a. The operation control unit 51a controls the navigation device 50 in two modes, a normal mode and an emergency mode. The normal time mode as the first operation mode is a default operation mode, and a route from the current position output from the GPS receiver 52 or a point specified by the user to a destination specified by the user is searched. A route, a traveling direction, and the like are displayed, and recommended spot information received from the server 100 via the communication unit 58 is displayed on the display unit 56. Alternatively, the search result searched by the server 100 based on the keyword or genre specified by the user is displayed on the display unit 56. That is, the normal mode is a mode in which the functions of the navigation device 50 can be used without limitation.

  The emergency mode as the second operation mode is an operation mode that is switched when the emergency information described above is received. In the emergency mode, the operation control unit 51a requires the user to respond urgently based on the emergency information. Therefore, some of the functions operated in the normal mode are limited. That is, some of the functions of the normal mode are limited. As a specific example, facility information related to emergency information such as an evacuation site is displayed without displaying the recommended spot information. Also, when searching, facilities related to emergency information are displayed in the search results without including recommended spot information. Examples of facilities related to emergency information include evacuation sites (temporary shelters, wide-area shelters, etc.) designated by local governments, fire stations, police stations, convenience stores, and gas stations, depending on the content of emergency information. And the location of public telephones.

  A GPS receiving unit 52 as a current position acquisition unit receives radio waves transmitted from a plurality of GPS (Global Positioning System) satellites as known, and obtains current position information (current position information) to obtain a control unit. To 51. In the present embodiment, an example in which the GPS receiving unit 52 is provided integrally with the navigation device 50 is shown, but the GPS receiving unit 52 may be configured as a separate body and detachable from the navigation device 50. .

  For example, in the case of a bicycle, the sensor input unit 53 receives an input from a cadence sensor or a speed sensor that measures the number of crank rotations per minute, a heart rate sensor that measures a user's heart rate, or the like. Output. In the case of an automobile, when the current position cannot be calculated by the vehicle speed sensor, the acceleration sensor, or the GPS receiving unit 52, an input from a self-supporting sensor or the like that calculates the current position is made and output to the control unit 51.

  The storage device 54 is composed of, for example, a hard disk or a non-volatile memory, and stores map data to be displayed on the route search and display unit 56, programs and data for the control unit 51 to control the navigation device 50, and the like. Reading and writing are performed under the control of the control unit 51.

  The operation unit 55 includes input means such as buttons and a touch panel, and voice input means such as a microphone. The operation unit 55 performs various input operations of the navigation device 50, and outputs a control signal indicating the input operation to the control unit 51.

  The display unit 56 includes a liquid crystal display and a driver circuit that controls the liquid crystal display. The display unit 56 is a facility related to recommended spot information and emergency information, which will be described later, such as map data, various icons, operation buttons, a route to the destination, a traveling direction, etc. on the liquid crystal display under the control of the control unit 51. Guidance information such as information and facility search results are displayed.

  The audio output unit 57 includes a speaker and an amplifier that drives the speaker, and outputs guidance voices, confirmation sounds, and the like during operation under the control of the control unit 51.

  The communication unit 58 as a receiving unit includes a circuit, an antenna, and the like for communicating with the network 101 described above. The communication unit 58 receives emergency information, guidance information, search results, and the like, which will be described later, from the server 100, and transmits current position information, search keywords, and the like output from the GPS reception unit 52 to the control unit 51 to the server 100. .

  For example, when the network 101 is a mobile phone network, the communication unit 58 is configured by a circuit, an antenna, or the like corresponding to a communication method such as LTE (Long Term Evolution) or W-CDMA (Wideband Code Division Multiple Access). When the network 101 is the Internet, the network 101 is configured by a circuit, an antenna, or the like corresponding to a wireless LAN (Local Area Network) standard communication method such as IEEE (Institute of Electrical and Electronics Engineers) 802.11 series.

  Server 100 communicates with navigation device 50 via network 100. The server 100 transmits to the navigation device 50 recommended spot information such as tourist facilities and commercial facilities around the current position acquired based on the current position information acquired from the navigation device 50 during normal times. The recommended spot information includes the name of the spot, an outline description of the spot, or an appearance photograph. This recommended spot is not included in facilities related to emergency information. In addition, when the server 100 acquires emergency information to be described later, the server 100 transmits facility information related to emergency information such as an evacuation place around the current position to the navigation device 50. Further, the server 100 searches for information on the peripheral facility at the current position based on the keyword and genre information acquired from the navigation device 50 and transmits the information to the navigation device 50.

  Further, for example, when the emergency information that affects the current position of the navigation device 50 is acquired or inputted from the outside, the server 100 transmits the emergency information to the navigation device 50. As emergency information, in addition to information on weather such as earthquakes, tsunamis, tornadoes, etc., it is necessary to notify the user of the navigation device 50 such as an accident such as a fire and take some measures such as evacuation. The source of emergency information may be not only TV / radio broadcasts but also information issued by public authorities such as the Japan Meteorological Agency, firefighting / police and local government (telephone, facsimile, e-mail, SNS (Social Networking Service), etc.) . Further, emergency information such as emergency earthquake bulletin included in television broadcasting, emergency information may be automatically extracted from an e-mail, SNS, or the like, or may be transmitted manually.

  In the configuration shown in FIG. 2, the navigation device 50 has map data, but map data may be acquired from the server 100 via the communication unit 58. Further, not only the map data but also the route information to be guided may be searched by the server 100, and the navigation device 50 may acquire and display the route searched by the server 100. Further, the server that performs map data and route search may be a server different from the server 100 shown in FIG.

  Next, operations in the normal mode and the emergency mode of the navigation device 50 configured as described above will be described with reference to the flowcharts of FIGS. The flowcharts shown in FIGS. 3 and 4 are executed by the control unit 51. These flowcharts may be configured as software (computer program) operating on the CPU configuring the control unit 51, or may be configured as hardware.

  First, a flowchart of the display operation on the display unit 56 shown in FIG. 3 will be described. In step S11 of FIG. 3, it is determined whether or not emergency information has been received via the communication unit 58. If received (YES), the process proceeds to step S14, and if not received (NO). Proceed to step S12. That is, this step functions as a reception process.

  Next, in step S12, based on the current position information output from the GPS receiving unit 52, the recommended spot information transmitted from the server 100 is displayed on the display unit 56, and the process proceeds to step S13. That is, when the server 100 approaches a predetermined range from a facility whose current position is a recommended spot, the server 100 transmits recommended spot information regarding the facility. In the navigation device 50, the recommended spot information received by the communication unit 58 is displayed on the display unit 56 under the control of the operation control unit 51a. That is, the recommended spot information corresponds to facility guidance information.

  A display example in this step is shown in FIG. In FIG. 5, a map and a pop-up P are displayed on the display unit 56. The current position C is displayed on the map as a substantially arrow-shaped icon, and the vertex of the arrow indicates the traveling direction. When the current position C approaches the recommended spot, the recommended spot information is received from the server 100 and the name of the spot (XX Jingu) is displayed in the pop-up P. When the user performs a selection operation such as touching the pop-up P, an outline description of the spot, an appearance photograph, or the like may be displayed. Further, a button, an icon, or the like for setting the spot as a destination may be provided in the outline explanation or the appearance photograph.

  Next, in step S13, it is determined whether or not the use of the navigation device 50 is to be ended, and when it is ended by operating the power button or the like (in the case of YES), it is ended. ) Proceeds to step S16.

  On the other hand, in step S14, it is determined that the emergency information has been received in step S11. Therefore, the emergency mode is switched to step S15.

  Next, in step S15, based on the current position information output from the GPS receiver 52, the evacuation site around the current position transmitted from the server 100 is displayed on the display unit 56. A display example in this step is shown in FIG. In FIG. 6, information such as the name of an evacuation site around the current position C (for example, the nearest) is displayed in a pop-up P. When the user performs a selection operation such as touching the pop-up P, the location or telephone number of the evacuation site may be displayed. Further, a button, an icon, or the like that sets the evacuation site as a destination may be provided. Further, instead of the pop-up P, it may be displayed directly on the map as an evacuation place (an icon that can be recognized as an evacuation place may be used). In addition, although shown in FIG. 6 as an evacuation place, it is good also as a fire station, a police station, a convenience store, a gas station, the position of a public telephone, etc. not only that but as mentioned above. Or you may make it select suitably according to the content of emergency information.

  By doing so, in the emergency mode, even if the current position approaches the recommended spot, the recommended spot information is limited and is not displayed, and only facilities related to emergency information such as an evacuation place are displayed. That is, when operating in the emergency mode, the recommended spot information is not displayed on the display unit 56 when the current position approaches a predetermined range from the recommended spot. Therefore, steps S14 and S15 function as an operation control process.

  In step S16, the current operation mode is determined, and in the normal mode, the process returns to step S11, and in the emergency mode, the process returns to step S15.

  In the flowchart shown in FIG. 3, in the emergency mode, the server 100 limits the display of the navigation device 50 by transmitting information related to emergency information (evacuation site), but the navigation device 50 side It may be limited by. For example, in the emergency mode, the operation control unit 51a restricts the recommended spot information from being displayed even if it is transmitted from the server 100. For example, by including identification information indicating recommended spot information in the recommended spot information, identification on the navigation device 50 side becomes possible.

  Next, the flowchart of the search operation shown in FIG. 4 will be described. In step S21 of FIG. 4, it is determined whether or not emergency information has been received via the communication unit 58. If received (YES), the process proceeds to step S25, and if not received (NO). Proceed to step S22.

  Next, in step S22, a normal search is performed and the process proceeds to step S23. The normal time search is a search in the normal time mode, in which a keyword or a genre input by the operation unit 55 or the like is transmitted to the server 100 and searched by the server 100.

  Next, in step S23, a search result is displayed and it progresses to step S24. As the search result, either a normal search performed in step S22 or an emergency search result performed in step S26 described later is displayed.

  Next, in step S24, it is determined whether or not the use of the navigation device 50 is to be ended, and when it is ended by operating the power button or the like (in the case of YES), it is ended, and when it is not ended (in the case of NO) ) Proceeds to step S27.

  On the other hand, in step S25, since it is determined that the emergency information has been received in step S21, the emergency mode is switched to step S26.

  Next, in step S26, an emergency search is performed and the process proceeds to step S23. The emergency search is a search in the emergency mode. For example, only search buttons are displayed without displaying input fields such as keywords and genres, and the server 100 is searched only for information on facilities related to emergency information. That is. By not inputting a keyword or the like, it is possible to promptly guide to an evacuation site or the like. Or you may limit the keyword etc. which are searched to predetermined phrases (an evacuation place, a convenience store, etc.). That is, the search range is limited because the search cannot be performed freely as in the normal time search.

  A display example of the search result in step S23 described above will be described with reference to FIGS. FIG. 7 shows an example in which a list is displayed on the display unit 56. FIG. 7A shows an example of a search result of a normal search, and FIG. 7B shows an example of a search result of an emergency search. FIG. 7A is an example using a temple and shrine as a keyword, and a search result as shown in FIG. 7A is displayed. On the other hand, since no keyword can be set in the emergency mode, for example, an evacuation site is displayed as shown in FIG.

  FIG. 8 is an example in which the search result is displayed on the map displayed on the display unit 56. FIG. 8A shows an example of a search result of a normal time search, and FIG. 8B shows an example of a search result of an emergency search. In FIG. 8A, a recommended spot Sp is displayed. In FIG. 8B, an evacuation site Sh is displayed. As shown in FIG. 7 and FIG. 8, in this embodiment, when searching for facilities, the search range is limited in the emergency mode, so the facilities displayed in the normal mode are different.

  As shown in FIG. 7 and FIG. 8, when operating in the emergency mode, the display unit 56 is displayed so that facilities other than facilities related to emergency information are not included in the search results.

  In the flowchart shown in FIG. 4, in the emergency mode, the search range is limited to the facility (evacuation site) related to the emergency information by the server 100, but may be limited on the navigation device 50 side. For example, by including identification information or the like in the facility information related to the emergency information, it is possible to restrict on the navigation device 50 side.

  In the case of a list display as shown in FIG. 7, more search results may be displayed by scrolling. In addition, the evacuation site and the like may be included in the search results in the normal mode. That is, in the normal mode, since the search function is not limited, the result may be freely displayed according to the search condition.

  According to the present embodiment, the navigation device 50 includes an operation control unit 51a that operates in any one of a normal mode and an emergency mode in which some of the functions of the normal mode are restricted, And a communication unit 58 that receives emergency information. Then, when the communication unit 58 receives emergency information, the operation control unit 51a switches from the normal mode to the emergency mode. In this way, when emergency information is received, it is possible to limit only operations related to emergency information. Therefore, for example, when emergency information related to an earthquake or tsunami is received, guidance suitable for the situation, such as guidance to an evacuation site, can be restricted by restricting guidance to a sightseeing spot.

  Moreover, since the GPS receiving part 52 which acquires the information regarding a present position and the display part 56 which displays the guidance information which guides a user are provided, the guidance information to arbitrary places from a present position is displayed. Can do.

  In addition, when the current position acquired by the GPS receiving unit 52 approaches a predetermined range from the recommended spot, the display unit 56 displays a name, an outline description, an appearance photograph, and the like regarding the recommended spot, and the operation control unit 51a When operating in the emergency mode, when the current position approaches within a predetermined range from the recommended spot, the display section 56 is restricted from displaying the name, outline description, appearance photograph, etc. regarding the recommended spot. . By doing in this way, it is possible to display only guidance information such as facilities related to emergency information without displaying the name, outline description, appearance photograph, etc. regarding the recommended spot that can be displayed in the normal mode.

  The display unit 56 displays a search result searched for facilities existing within a predetermined range from the current position acquired by the GPS receiving unit 52. When the operation control unit 51a operates in the emergency mode, Since the facility other than the facility related to the information is displayed on the display unit 56 without being included in the search result, only the result that is desired to be displayed when receiving emergency information such as an evacuation site can be displayed. Therefore, the position of the evacuation site can be easily searched, and the display of the evacuation site and the route search can be easily performed.

  In the embodiment described above, the navigation device 50 communicates with the server 100 to obtain recommended spot information, evacuation locations, search results, and the like. However, the recommended spot information, evacuation locations, etc. are stored in the storage device 54 in advance. Or downloaded from a memory card or the like and stored, and recommended spot information and evacuation sites may be displayed or searched based on information stored in the storage device 54.

  In the above-described embodiment, among the functions (for example, pop-up display and search) that the navigation device 50 has, some of the functions are limited in the emergency mode. You may restrict | limit so that only a specific function can be used in the emergency mode among the functions which have. For example, only the route guidance function to the evacuation site can be used in the emergency mode.

  In the emergency mode, not only the name of the evacuation site and the like are displayed on the pop-up P, but also a message from a business operator or a local government that manages the server 100 may be displayed.

  In the above-described embodiment, only one navigation device 50 is shown, but it goes without saying that there are a plurality of navigation devices 50 and each can access the server 100. Further, a plurality of navigation devices 50 may be grouped. When grouped, a message or the like may be transmitted from one navigation device 50 in the group to another navigation device 50. For example, in the case of the emergency mode, it is possible to use information such as transmitting information on an evacuation site designated by a user of one navigation device 50 in the group to another navigation device 50 in the group.

  Further, the present invention is not limited to the above embodiment. That is, those skilled in the art can implement various modifications in accordance with conventionally known knowledge without departing from the scope of the present invention. Of course, such modifications are included in the scope of the present invention as long as the configuration of the guide device of the present invention is provided.
