Description

  The present invention relates to a mobile communication device, and more particularly to an operation for outputting information in an emergency situation such as when an earthquake occurs.

  When an emergency situation occurs, for example, when a disaster occurs or is likely to occur, information related to the emergency situation, such as disaster prevention information such as details of the disaster and evacuation methods from the emergency situation, is output. A mobile communication device is desired. Since the mobile communication device is a portable device, it is desired to output useful information when evacuating on foot. Here, the mobile communication device may be a device having a broadcast receiving function, or may be a device not having the function.

  Regarding the occurrence of a disaster, a forecast of the occurrence of an earthquake or tsunami can be obtained by receiving an emergency alert broadcast that is performed in front of an emergency alert signal. Regardless of whether it is a digital system or an analog system, emergency alert broadcasting is performed by television broadcasting and radio broadcasting, and can be obtained by receiving these broadcasts. A method is known in which the operation of a device that automatically receives a broadcast is stopped and an operation is automatically started when an emergency warning signal is received when the device is in a standby state.

  Here, the digital television broadcast is a system using all 13 segments (sometimes referred to as full segment), or a system using a part of segments (sometimes referred to as one segment). It doesn't matter if it is. Digital radio broadcasts are sometimes referred to as 3 segments.

  Similarly, when an earthquake early warning is delivered by the Japan Meteorological Agency, regardless of whether the early warning is a digital method or an analog method, a method widely known by television broadcasting and radio broadcasting is known. In addition, a method is known in which earthquake early warning is notified from a mobile communication carrier by simultaneous broadcast delivery to a mobile phone contracted with the carrier or by sending an e-mail. Furthermore, information related to disasters other than earthquakes and tsunamis, such as forecasts of heavy rain, can be obtained by receiving broadcasts.

In addition to video signals and audio signals, digital television broadcasting includes a caption signal and a data signal described in BML (Broadcast Markup Language) language. Therefore, a mobile communication device having a digital television broadcast receiving function selects an appropriate part of the description in the BML language in addition to the television broadcast video signal, audio signal, and caption signal, and the BML. By obtaining the address of the web server device via the description in the language and accessing the address via the mobile communication network, more detailed information than the broadcasted information, for example, information depending on the location where the device exists Is known (see, for example, Patent Document 1).

  When it is detected that the disaster prevention information output control unit 21 has changed to an emergency situation, the following three types of disaster prevention information are displayed on the display unit 15 in accordance with the amount of power stored in the storage battery 31c of the power supply unit 31. The sound is displayed and the sound is output from the speaker 23. In addition, when the storage battery 31c is charging, it is considered that the said electric energy is large.

  First, when the power amount is medium, the disaster prevention information output control unit 21 operates the broadcast receiving unit 22 to display the digital television broadcast video signal and the caption signal on the display unit 15, and The sound signal of the broadcast is output from the speaker 23 as sound. Further, the browser unit 22g is operated according to the description in the BML language included in the broadcast. Information obtained by the broadcast receiving unit 22 is stored in the storage unit 25 as first disaster prevention information 25c.

  Secondly, when the amount of electric power is large, the disaster prevention information output control unit 21 operates the browser unit 24, and the disaster prevention information related to the position stored in the storage unit 25 as the current position information 25a is stored in the predetermined web server device SV. To get from. Then, the video signal of the obtained disaster prevention information is displayed on the display unit 15, and the audio signal of the information is output from the speaker 23. Information obtained when an emergency situation occurs by the browser unit 24 is stored in the storage unit 25 as second disaster prevention information 25d.

  3rdly, when the said electric energy is small, the disaster prevention information output control part 21 is output before the emergency situation generate | occur | produces, and makes the information memorize | stored in the memory | storage part 25 as the 3rd disaster prevention information 25e output. That is, the information video signal is displayed on the display unit 15, and the audio signal of the information is output from the speaker 23.

  The third disaster prevention information 25e obtained before the occurrence of this emergency and stored in the storage unit 25 is obtained by the disaster prevention information output control unit 21 operating the browser unit 24 in advance, or The information is stored before the device is shipped, and is stored in the storage unit 25 in association with the location of the disaster prevention information. Therefore, the disaster prevention information output control unit 21 outputs the third disaster prevention information 25e associated with the current position information 25a.

  The operation of each part of the broadcast receiving unit 22 will be described. The tuner unit 22b is activated by the control unit 11, selects a channel signal having a channel number designated by the control unit 11 from a high-frequency signal transmitted from the broadcast station BC and received by the antenna 22a. Then, the selected high-frequency signal is converted into an intermediate-frequency signal, and the converted signal is demodulated to obtain a digitally broadcast signal.

  The tuner unit 22b may include a connection unit (not shown), and may receive a high-frequency signal from the antenna 22a via a cable connected to the connection unit. The cable may be connected to a second broadcast receiving antenna (not shown).

  The DEMUX unit 22c receives the broadcasted signal obtained by the tuner unit 22b and separates the signal into a video signal, an audio signal, a caption signal, and a data signal. Then, the separated video signal and audio signal are transmitted to the decoder unit 22d, the separated caption signal is transmitted to the caption processing unit 22e, and the separated data signal is transmitted to the DSMCC unit 22f. Further, the DEMUX unit 22c detects whether or not an emergency warning signal has been received, and if it is detected that it has been received, notifies the control unit 11 to that effect.

  The decoder unit 22d receives and decodes the video signal and the audio signal. Then, the decoded video signal is displayed on the display unit 15. Further, the decoded audio signal is generated as audio from the speaker 23. Note that the video signal and the audio signal are encoded by, for example, an MPEG-2 encoding method and transmitted from the broadcasting station BC.

  Further, the decoder unit 22d analyzes the decoded video signal and audio signal to detect whether or not the earthquake early warning has been broadcast. When it is detected that the broadcast has been broadcast, the decoder unit 22d notifies the control unit 11 accordingly. To do. Furthermore, regardless of whether or not an earthquake early warning is broadcast, it is detected whether a disaster has occurred or whether it is predicted that a disaster will occur. 11 is notified of this.

  The caption processing unit 22e receives the caption signal and decodes it. Then, the decoded subtitle information is displayed on the display unit 15. The display by the decoder unit 22d and the display by the caption processing unit 22e are controlled by the control unit 11 so that they are not displayed at the same position on the display screen of the display unit 15.

  Also, the caption processing unit 22e detects whether or not the earthquake early warning has been broadcast by analyzing the decrypted caption information, and notifies the control unit 11 when it is detected that the broadcast has been broadcast. Furthermore, regardless of whether or not an earthquake early warning is broadcast, it is detected whether a disaster has occurred or whether it is predicted that a disaster will occur. 11 is notified of this.

  The DSMCC unit 22f receives and decodes the data signal. Then, the decrypted data signal is transmitted to the browser unit 22g. Also, an event signal included in the decoded data signal is detected. The decoded data signal is information described in BML (Broadcast Markup Language) language.

  The browser unit 22g is a BML browser, and stores the received information described in the BML language in the storage unit 25 as the first disaster prevention information 25c. The information includes a signal displayed on the display unit 15 or generated as sound from the speaker 23, and a signal indicating an event for controlling the display and sound generation, for example. Then, when the event is included in the received description in the BML language, the browser unit 22g performs an operation according to the event.

  The operation of the browser unit 22g according to the event is, for example, a predetermined portion (sometimes referred to as a page) in the description in the BML language stored in the storage unit 25 as the first disaster prevention information 25c. Is displayed on the display unit 15 and an audio signal included in the image is transmitted to the speaker 23 to generate audio. Another example is starting a script written in the BML language.

  Here, the video of information described in the BML language includes all those described as still images, moving images, and characters in the BML language. The display by the decoder unit 22d and the display by the browser unit 22g are controlled by the control unit 11 so that they are not displayed at the same position on the display screen of the display unit 15.

  Note that the information referred to by the browser unit 22g is not limited to the range of description in the received BML language. For example, an image of information described in HTML (HyperText Markup Language) language stored in the web server device SV is displayed on the display unit 15 via the transmission / reception unit 13 and the base station BS, and an audio signal of the information is displayed on the speaker 23. To generate sound.

  The broadcast receiving unit 22 may be placed in a standby state when the above operation is not performed. When placed in the standby state, the broadcast receiving unit 22 operates the tuner unit 22b and the DEMUX unit 22c, and when the DEMUX unit 22c detects that an emergency warning signal has been received, the DEMUX unit 22c The control unit 11 is notified to that effect.

  When placed in a standby state, the tuner unit 22b receives a channel having a channel number designated by the control unit 11. This channel is preferably a channel that broadcasts an emergency alert signal. Therefore, a channel broadcast by the Japan Broadcasting Corporation designated as a designated public institution based on the Disaster Countermeasure Basic Act is appropriate, but it is not limited to this channel. It may be a channel designated by a predetermined key operation of the input device 16. For example, it is a channel of a broadcasting station BC that includes a location where the mobile communication device MS exists in a broadcast target area and performs detailed broadcasting related to an emergency in that area.

  The browser unit 24 is activated by the control unit 11 in response to a predetermined key operation of the input device 16 or based on an instruction from the disaster prevention information output control unit 21, specifies a web page address, and the web server device SV To the information described in the HTML language stored in. Here, the web page address is obtained by a predetermined key operation of the input device 16 or by designation from the disaster prevention information output control unit 21.

  And the browser part 24 memorize | stores the information received from web server apparatus SV in the memory | storage part 25 as 2nd disaster prevention information 25d, and it is a video signal regardless of whether it is a still image or a moving image among the information. Is displayed on the display unit 15, and an audio signal is output from the speaker 23. And / or the browser part 24 memorize | stores the signal received from web server apparatus SV in the memory | storage part 25 as the 3rd disaster prevention information 25e. In this storage, information indicating the position where the mobile communication device MS exists, which is measured by the positioning unit 17, and the web page address from which the third disaster prevention information 25e is obtained are stored in association with each other.

  Next, the operation of the power supply unit 31 will be described with reference to FIG. The charger connection detection unit 31a measures the voltage of power supplied from the charger CH via the connector. Then, it is detected whether or not the charger CH is connected to the power supply unit 31 by supplying DC power that can charge the storage battery 31c.

  That is, the charger connection detection unit 31a starts the operation in response to an instruction from the control unit 11, and detects that the charger CH is connected if the measured voltage is equal to or greater than a predetermined chargeable voltage threshold value. If the voltage is less than the threshold value, it is detected that the charger CH is not connected. And it notifies the control part 11 whether the charger CH is connected.

  The switch 31b starts operating in response to an activation signal from the control unit 11, and electrically disconnects or turns on between a power terminal (not shown) supplied from the charger CH via a connector and the storage battery 31c. To do. The storage battery 31c is charged with DC power of a predetermined voltage supplied from the charger CH when the charger CH is connected and the switch 31b is turned on. The storage battery 31c supplies power to each operating part in the mobile communication device MS.

  The voltage measurement unit 31d starts operation in response to an activation signal from the control unit 11, and measures the voltage supplied by the storage battery 31c. Then, the control unit 11 is notified of the measured voltage. This voltage measurement is performed as a measurement of the amount of electric power stored in the storage battery 31c. This is because the measured voltage serves as an index of the amount of power stored in the storage battery 31c.

  Note that the measurement of the amount of power stored in the storage battery 31c is not limited to being performed by measuring the voltage supplied by the storage battery 31c. The power supply unit 31 may measure the amount of power stored in the storage battery 31c by measuring the amount of power charged in the storage battery 31c and the amount of power discharged from the storage battery 31c. For this measurement, the power supply unit 31 includes, for example, a dedicated circuit that measures the amount of power and a dedicated circuit that calculates the difference between the two amounts of power.

  Hereinafter, in the mobile communication device MS according to the embodiment of the present invention, a process of outputting information related to a disaster obtained by an appropriate method according to the amount of power stored in the storage battery 31c will be described.

(First operation, that is, processing when it is determined that there is no emergency)
If the emergency information output control unit 21 is not an emergency, that is, if the emergency information 25b is not stored as an emergency, the browser unit 24 outputs useful disaster prevention information when an emergency occurs at the location where the device exists. The useful disaster prevention information is stored in the storage unit 25 as the third disaster prevention information 25e. At the time of this storage, information indicating the position where the device is present and the web page address used for accessing the useful disaster prevention information are stored in association with each other.

  That is, the browser unit specifies the name of the local government, etc., including the position where the device that is measured by the positioning unit 17 and stored in the current position information 25a is included, and keywords such as “evacuation route” and “evacuation place” In the above-described position, information useful in the event of an emergency situation, for example, a map around the evacuation site and the evacuation route to the evacuation site are retrieved from the web information stored in the web server device SV. This search can be performed at a search site stored in the web server device SV.

  The search process consumes the electric power stored in the storage battery 31c. Therefore, the disaster prevention information output control unit 21 is measured when the charger CH is connected to the device by the charger connection detection unit 31a, or when the amount of electric power stored in the storage battery 31c by the voltage measurement unit 31d is large. Make it happen only.

  In addition, although it is desirable to store disaster prevention information that is useful in many locations and in the event of an emergency, a predetermined distance is required to reduce power consumption and storage capacity used by the storage unit 25. Store disaster prevention information when an emergency occurs at a remote location. The distance between the two positions is calculated by the latitude and longitude of each position. Furthermore, disaster prevention information is stored when an emergency occurs at a location where the device exists for a long time. The time for which the device exists is obtained by operating the positioning unit 17 at a predetermined time interval.

  In addition, disaster prevention information when an emergency occurs at a certain position may be updated. Therefore, the third disaster prevention information 25e stored in the storage unit 25 in the past exceeding the predetermined time is again searched for and stored in the browser unit 24. The predetermined time is several months, for example.

  Further, the disaster prevention information output control unit 21 sends useful disaster prevention information to the browser unit 24 when an emergency occurs at a position where the device exists based on a predetermined key operation of the input device 16. The useful disaster prevention information may be obtained and stored in the storage unit 25 as the third disaster prevention information 25e. At the time of this storage, information indicating the position where the device is present and the web page address used for accessing the useful disaster prevention information are stored in association with each other. This storage may be new storage or update storage.

(Second operation, that is, processing when it is determined that an emergency has occurred)
An operation of outputting information related to a disaster obtained by an appropriate method of the disaster prevention information output control unit 21 when it is determined that the situation has changed to an emergency will be described. FIG. 5 shows a flowchart of an operation of outputting information related to a disaster obtained by an appropriate method of the disaster prevention information output control unit 21. The disaster prevention information output control unit 21 is started when the mobile communication device MS is turned on and starts an operation of outputting information related to a disaster obtained by an appropriate method, and stores the information stored in the emergency information 25b. Erasing is performed (step S101).

  The disaster prevention information output control unit 21 determines whether or not an emergency situation has occurred (step S102). That is, in the following cases, the disaster prevention information output control unit 21 determines that an emergency has occurred, and stores the emergency information 25b in the storage unit 25 as emergency information 25b. In addition, the positioning unit 17 measures the latitude and longitude of the position where the device is present, and stores information indicating the position obtained by the positioning in the storage unit 25 as current position information 25a.

  First, when the DEMUX unit 22c notifies that an emergency warning signal has been received, the emergency warning signal is measured by the positioning unit 17 and there is a device stored in the current position information 25a. This is a case where the signal is for a region indicated by information indicating the position to be operated.

  In addition, when the position where the device exists is far away from the coast or estuary, and when the altitude of the position is equal to or higher than a predetermined value, the disaster prevention information output control unit 21 outputs the emergency warning signal related to the tsunami warning. It may not be determined that an emergency has occurred due to reception. This is because the risk of a tsunami disaster is very small.

  Secondly, the decoder unit 22d and / or the caption processing unit 22e is notified that an emergency earthquake bulletin has been broadcast. Third, the decoder unit 22d and / or the caption processing unit 22e is notified that a disaster has occurred or that a disaster is expected to have been broadcast.

  Fourthly, a case where a simultaneous broadcast distribution for notifying an emergency situation, for example, a simultaneous broadcast distribution for notifying an emergency earthquake warning, transmitted from the base station BS is received via the transmission / reception unit 13. This distribution may be in the form of an e-mail. Fifth, it is a case where a predetermined key operation of the input device 16 is performed.

  Thus, the disaster prevention information output control unit 21 uses the fact that the emergency warning signal has been received as one means for determining that the emergency has changed. Therefore, it is desirable for the disaster prevention information output control unit 21 to place the broadcast receiving unit 22 in a standby state when the broadcast receiving unit 22 is not operating.

  If it is determined by the operation for determining whether or not the emergency has occurred in step S102, the disaster prevention information output control unit 21 determines whether or not the emergency has occurred in step S102. The judgment operation is repeated.

  On the other hand, when it is determined that an emergency has occurred, the disaster prevention information output control unit 21 determines whether or not the charger CH is connected to the mobile communication device MS based on a notification from the charger connection detection unit 31a. Based on the notification from the unit 31d, it is determined whether or not the amount of power stored in the storage battery 31c is large, that is, whether or not it is larger than the first power amount threshold (step S103).

  If it is determined that the charger CH is connected to the mobile communication device MS or that the amount of power stored in the storage battery 31c is large, the disaster prevention information output control unit 21 instructs the browser unit 24 to The apparatus SV is accessed to a predetermined web page, and it is determined whether or not the access is possible (step S104).

  Here, when the distance between the mobile communication device MS and the base station BS is large, or there is an obstacle between them, and there is a failure in radio wave propagation between them, the web server device SV If the operation is not smooth, for example, when many accesses are concentrated, it becomes impossible to access the web server device SV.

  Here, the predetermined web page is a page identified by the web page address received by the broadcast receiving unit 22. The web page address is included in the video signal or the audio signal, is included in the address analyzed by the decoder unit 22d, the subtitle signal, is analyzed by the subtitle processing unit 22e, and is included in the description in the BML language. Either the address extracted by the DSMCC unit 22f or the address included in the description in the BML language and reached by execution of the browser unit 22g.

  When a plurality of these addresses are prepared and can be selected depending on the position where the mobile communication device MS exists, the disaster prevention information output control unit 21 instructs the positioning unit 17 to determine the latitude of the position where the mobile communication device MS exists. Then, the position corresponding to the position where the mobile communication device MS exists is selected by referring to the information indicating the position obtained by the positioning and positioning the longitude.

  Further, the web page address may be an address that is distributed along with the simultaneous broadcast distribution that notifies an emergency situation. Further, the web page address may be stored in the storage unit 25 in association with information indicating the position. For example, it is a case where an address for obtaining disaster prevention information related to the local government is stored for each local government.

  Further, the web page address is an address stored in the storage unit 25 in association with the third disaster prevention information 25e and information indicating the position where the mobile communication device MS exists, which is measured by the positioning unit 17. Also good. By referring to the position where the mobile communication device MS exists, the relationship between the web page address obtained in the past and the position of the mobile communication device MS when the address is obtained can be utilized.

  If access is possible in step S104, the disaster prevention information output control unit 21 instructs the browser unit 24 to access the web page of the web server device SV, and as a result, the web server device SV. Is stored in the storage unit 25 as the second disaster prevention information 25d, the video signal in the signal is displayed on the display unit 15, and the audio signal is output from the speaker 23 as audio. (Step S105), and the operation of outputting information related to the disaster obtained by an appropriate method is terminated (Step S106). Note that the end of the operation of the disaster prevention information output control unit 21 does not mean the end of the operation of the browser unit 24.

  The second disaster prevention information 25d stored in step S105 is used as a buffer related to communication with the web server device SV. In addition, it is used to continue displaying video signals and outputting audio signals when communication occurs with the web server device SV.

  The disaster prevention information output control unit 21 may store the signal received by the browser unit 24 in the storage unit 25 as the third disaster prevention information 25e. At the time of this storage, information indicating the position where the mobile communication device MS exists, which is measured by the positioning unit 17, and the web page address are stored in association with each other. As will be described later, the third disaster prevention information 25e is used when it is not appropriate to communicate with the web server device SV.

  If access is impossible in step S104, the disaster prevention information output control unit 21 stops the operation of the browser unit 24 and determines whether broadcast reception by the broadcast reception unit 22 is possible (step S107). . The channel received at this time is appropriately a broadcast channel by the Japan Broadcasting Corporation for the reasons described above, but is not limited to this channel.

  For example, priority may be given to a channel through which broadcast reception is possible. The determination of whether or not broadcast reception is possible is based on, for example, the strength of the radio wave received by the tuner unit 22b. Further, it depends on the ratio of video signals and audio signals in which transmission errors are detected during decoding by the decoder unit 22d.

  When the broadcast reception is possible, the disaster prevention information output control unit 21 operates the broadcast reception unit 22 (step S108), and ends the operation of outputting information related to the disaster obtained by an appropriate method (step S106). ). Note that the end of the operation of the disaster prevention information output control unit 21 does not mean the end of the operation of the broadcast receiving unit 22.

  Here, if the broadcast receiving unit 22 is operating in step S108, it is not necessary to operate it again. Further, as described in the operation of step S107, the channel selected by the tuner unit 22b is a broadcast channel by the Japan Broadcasting Corporation.

  In step S108, when a data signal which is a description in the BML language is received by the broadcast receiving unit 22, the signal is output by the execution of the browser unit 22g. When the description in the BML language consists of a plurality of parts and the browser unit 22g can select any part depending on the position where the mobile communication device MS exists, the disaster prevention information output control unit 21 includes the positioning unit 17 To determine the latitude and longitude of the position where the mobile communication device MS exists, and select the portion corresponding to the position where the mobile communication device MS exists based on the information indicating the position obtained by the positioning.

  If the broadcast reception is impossible in step S107, the disaster prevention information output control unit 21 stops the operation of the broadcast reception unit 22, instructs the browser unit 24, and is positioned by the positioning unit 17, and the mobile communication device The video signal of the 3rd disaster prevention information 25e linked | related with the information which shows the position where MS exists is displayed on the display part 15, an audio | voice signal is audio-outputted from the speaker 23 (step S109), and it was obtained by the appropriate method The operation of outputting information relating to the disaster is terminated (step S106). Note that the end of the operation of the disaster prevention information output control unit 21 does not mean the end of the operation of the browser unit 24.

  In step S103, when the charger CH is not connected to the mobile communication device MS and the amount of power stored in the storage battery 31c is not large (“NO” in step S103), the disaster prevention information output control unit 21 The controller 11 is instructed to determine whether or not the amount of power stored in the storage battery 31c is greater than the second power amount threshold value that is smaller than the first power amount threshold value described above (step S110).

  When the amount of power stored in the storage battery 31c is larger than the second threshold value ("medium" in step S110), the disaster prevention information output control unit 21 determines whether or not broadcast reception by the broadcast reception unit 22 in step S107 is possible. It moves to the operation after the operation of judging. When the amount of power stored in the storage battery 31c is smaller than the second threshold value (“low” in step S110), the disaster prevention information output control unit 21 instructs the browser unit 24 in step S109 to provide third disaster prevention information 25e. The video signal is displayed on the display unit 15 and the operation proceeds to the operation after the operation of outputting the audio signal from the speaker 23 as audio.

  Note that the disaster prevention information output control unit 21 is activated at a predetermined time interval after the operation ends, and even if the mobile communication device MS has moved during the time interval, the operation of step S104 or the operation of step S108 is performed. The browser unit 24 that started the operation or the broadcast receiving unit 22 that started the operation by the operation of step S107 always outputs information suitable for the position where the mobile communication device MS exists (not shown). That is, the disaster prevention information output control unit 21 instructs the positioning unit 17 to measure the latitude and longitude of the position where the mobile communication device MS exists. Then, the browser unit 24 or the broadcast receiving unit 22 is made to output information suitable for the position obtained by positioning.

  In addition, the disaster prevention information output control unit 21 is activated at a predetermined time interval after the operation is finished, and determines whether it is an emergency. That is, it is determined that there is no emergency when a predetermined time has elapsed after the decoder 22d and / or the caption processing unit 22e determines that the broadcast indicating the content of the emergency has ended. Then, after it is determined that the situation is not an emergency situation, the information stored in the emergency information 25b is deleted, and the operation after the operation of Step S102 is performed again (not shown).

  Before moving to the operation of step S102, the disaster prevention information output control unit 21 has the browser unit 24 started to operate by the operation of step S104 or the operation of step S108, or the broadcast receiving unit 22 started to operate by the operation of step S107. End the operation. However, this operation end may be performed based on a predetermined key operation of the input device 16.

  With the above operation, the disaster prevention information output control unit 21 instructs the browser unit 24 when the charger CH is connected to the mobile communication device MS or the amount of power stored in the storage battery 31c is large, and the web server device The latest and detailed disaster prevention information stored in the SV is output together with, for example, a detailed map and a display of an evacuation route on foot. For this operation, it is essential to operate the communication unit 12b and the transmission / reception unit 13 for communication with the web server device SV, and power consumption is large.

  Moreover, when the electric energy stored in the storage battery 31c is medium, the broadcast receiving unit 22 is instructed to output the latest disaster prevention information broadcast from the broadcast station BC. For this operation, it is essential to operate the broadcast receiving unit 22 and to decode the video signal and the audio signal, and the power consumption is medium.

  Further, when the amount of power stored in the storage battery 31c is small, the disaster prevention information output control unit 21 instructs the browser unit 24 to output the third disaster prevention information 25e stored in the storage unit 25. The power consumption of this operation is small. However, the information related to the disaster obtained by an appropriate method that matches the position where the mobile communication device MS exists is output.

  In the above description, the disaster is an earthquake or tsunami, but is not limited to this. In addition to natural disasters such as typhoons, heavy rains, and volcanic explosions, human disasters such as railway network accidents, road congestion, and fires are also acceptable. Moreover, although disaster prevention is information related to evacuation from a disaster, for example, presentation of an evacuation route, it is not limited to presentation of information related to condemnation. When a tsunami occurs, it may be general-purpose information such as that it should move to a higher position, or it may present a route that bypasses the position where an accident or traffic jam occurred. Moreover, the information which shows the detail of a disaster may be sufficient.

  In the above description, the disaster prevention information output control unit 21 is activated when the mobile communication device MS is turned on and operates continuously, although it is intermittent, it is not limited thereto. For example, it may be activated by a predetermined key operation of the input device 16.
