Description

  The present invention relates to a mobile terminal device such as a mobile phone, a PHS, a PDA, and a portable personal computer having a communication function, and more particularly to a mobile terminal device and an emergency assistance notification method for expanding functions added to the communication function. About.

  Mobile terminal devices such as mobile phones, PHS (Personal Handy-phone System), and PDA (Personal Digital Assistant) are different from communication terminals that are shared by multiple people, such as fixed telephones. It is used as a thing to manage. For this reason, in addition to the original communication function, various functions such as a schedule management function are incorporated, and it is the most representative thing that an individual always carries. In particular, recently, it has become possible to purchase products using vending machines and use transportation even without having to carry a wallet or commuter pass, and it has become increasingly impossible to give up mobile terminal devices.

  By the way, in recent years, natural disasters such as earthquakes, tsunamis, and heavy snow have occurred frequently, and interest in disaster prevention and emergencies is increasing. The mobile terminal device exerts great power when a disaster occurs due to its communication function. In other words, by using the communication function, it is possible to ask for help in the surroundings and to teach others where to be. In particular, in the case of a portable terminal device equipped with a GPS (Global Positioning System) function, it is possible to quickly find and help those who are confined or lost their place due to a disaster by incorporating the location of the sender in the mail. become able to.

  However, the portable terminal device is a wireless terminal that is premised on communicating with a desired counterpart via a wireless base station. For this reason, for example, when a wide-area disaster such as an earthquake or a wide-area fire occurs, the radio base station itself is often destroyed or lost, and the function cannot be performed. In such a case, the wireless communication function as the original function of the communication terminal input device cannot be utilized. Therefore, a mobile terminal device that can notify the user of his / her whereabouts even when radio cannot be used in an emergency has been proposed as a first proposal (see, for example, Patent Document 1).

  The portable terminal device according to the first proposal is provided with a horn device that emits a horn sound by blowing into the top of the antenna rod. Therefore, for example, when a building collapses and is buried alive due to an earthquake, for example, it is possible to notify other people of his / her whereabouts using a horn. However, according to the first proposal, it is necessary for the user to blow into the horn means strongly every time the horn sound is emitted. The work of breathing consumes a relatively large amount of energy. Also, a lot of water is discharged from the body with breathing. Therefore, there is a problem that the physical strength is rapidly consumed.

Therefore, a second proposal is to incorporate an alarm buzzer into a mobile phone (see, for example, Patent Document 2). This second proposed alarm generation unit is set to be driven when a predetermined switch is turned on. Further, the alarm generation unit includes a speaker, and generates an alarm sound of 80 dB (decibel) or 100 dB or more therefrom. Therefore, according to the second proposal, it is possible to prevent the occurrence of violent crimes against weak people such as children and women by flowing an announcement such as “Please help” from the speaker at a loud volume, earthquakes, etc. In the event of a disaster, you can be alerted to your presence.
Japanese Patent Laying-Open No. 2003-298710 (paragraph 0009, FIG. 1) Japanese Patent Laying-Open No. 2003-060752 (Nos. 0021, 0042, 0044, FIG. 2)

  By the way, in the second proposal, a sound of at least 80 dB or more is generated in order to prevent a crime such as a molester. Therefore, it is very effective in some cases to use the proposed mobile phone at the site of burying. However, since an alarm is generated with a loud sound, it is very difficult for a user of a mobile phone to listen to the sound continuously for a long time in a closed space. In addition, when a plurality of objects are buried alive and a sick person or an infant is included, the person is shocked each time a warning sound is generated with loud sound. For this reason, the alarm sound can be output only occasionally. In addition, there is a problem that when a warning sound is output, it is impossible to find a location unless there is a person who is performing a rescue operation in the vicinity.

  Accordingly, an object of the present invention is to provide a portable terminal device that can notify the user of his / her presence without hesitation when he / she is isolated from the outside, for example, when he / she is buried or confined.

For this reason, even in an environment in which the battery is normally discharged and communication cannot be performed, wireless communication can be performed to notify the presence of the user to the outside.

  In the present invention, (a) power generation means for generating power by hand, (b) charging means for charging with power generated by the power generation means, and (c) dog whistle using power charged by the charging means. The portable terminal device is provided with a dog whistle generating means for generating an ultrasonic wave having a frequency corresponding to the above, (d) a switch for driving the dog whistle generating means, and (e) a wireless communication means for performing wireless communication.

  That is, in the present invention, since the portable terminal device itself is provided with power generation means for generating power by turning, the power generated by the power generation means is charged by the charging means, and when the notification is necessary, the dog whistle generating means is performed by the switch. Or wireless communication can be performed by wireless communication means.

  Further, according to the present invention, (b) emergency assistance request means for generating an emergency assistance request, and (b) wireless communication with a predetermined contact address when the emergency assistance request means generates an emergency assistance request. A wireless communication availability determination means for determining whether an emergency assistance request is possible; and (c) communication of an emergency assistance request with predetermined contents when the wireless communication availability determination means determines that wireless communication is possible. And (d) the dog whistle after the emergency assistance request communication by the emergency assistance request communication means is performed and when the wireless communication availability determining means determines that wireless communication is impossible. And a dog whistle generating means for generating an ultrasonic wave having a frequency corresponding to

  That is, in the present invention, when the emergency assistance request means including a switch that can be operated by the user generates an emergency assistance request, the wireless communication availability determination means can request emergency assistance by radio to a predetermined contact address. It is decided to determine whether it is. Then, the emergency assistance request communication means communicates an emergency assistance request with predetermined contents when the wireless communication availability determination means determines that wireless communication is possible. The dog whistle generating means has a frequency exceeding the frequency corresponding to the dog whistle after the emergency help request communication is performed by the emergency help request communication means and when the wireless communication enable / disable determining means determines that wireless communication is impossible. Generates sound waves. Therefore, it is possible to make a request for emergency assistance by both wireless communication and dog whistle when wireless communication is possible, and by dog whistle when wireless communication is impossible. In particular, dog whistle responds to this, so when the request for wireless assistance is in a geographically distant location, the occurrence of a dog whistle can be a major force in requesting emergency assistance. obtain.

It is decided at the step of determining whether or not wireless communication is possible. When it is determined that the wireless communication of the emergency assistance request is possible, the emergency assistance request communication is performed with the contents predetermined in the emergency assistance request communication step, and further the communication is performed in the emergency assistance request communication step. When it is determined that wireless communication is not possible in the wireless communication enable / disable determination step, an ultrasonic wave having a frequency corresponding to the dog whistle is generated in the dog whistle generation step. Therefore, it is possible to make a request for emergency assistance by both wireless communication and dog whistle when wireless communication is possible, and by dog whistle when wireless communication is impossible. In particular, dog whistle responds to this, so when the request for wireless assistance is in a geographically distant location, the occurrence of a dog whistle can be a major force in requesting emergency assistance. obtain.

  As described above, according to the present invention, since the portable terminal device outputs an ultrasonic wave such as a dog whistle by operating the switch, the presence of oneself can be communicated to others via an animal or a measuring instrument without bothering the surroundings. You can be notified. Therefore, the original communication function of the mobile terminal device can be supplemented. In particular, when the communication function does not function during a disaster or the like, the output of ultrasonic waves such as a dog whistle is a great force for confirming the presence of the sender.

  Further, in the present invention, since the power generation means for generating electric power by hand is provided, it is possible to easily eliminate the situation where wireless communication is impossible due to battery exhaustion or ultrasonic output such as a dog whistle is impossible.

  Hereinafter, the present invention will be described in detail with reference to examples.

  FIG. 1 shows a mobile phone as a mobile terminal device according to a first embodiment of the present invention as viewed from the front side. The device main body 102 of the cellular phone 101 has an elongated rectangular parallelepiped shape that is large enough to be held by a user with one hand. On the front side (front side) of the apparatus main body 102 shown in this figure, a speaker 104 is arranged on the upper end side (right side in the figure) where the antenna 103 exists, and on the lower end side (left side in the figure). 105 is arranged. These correspond to a handset handset and a handset of a fixed telephone (not shown). Between the speaker 104 and the microphone 105, a display unit 106 made up of a liquid crystal display or an organic EL (Electro Luminescence) display and an operation unit 107 made up of various keys (not shown) such as numeric keys are arranged. The speaker 104, the microphone 105, the display unit 106, and the operation unit 107 have a life waterproof function together with the apparatus main body 102. This is to ensure that the normal operation is ensured as much as possible even when the mobile phone 101 is stored in a user's pocket or the like in a severe environment such as a disaster.

  FIG. 2 is a view of the cellular phone from the back side. A dog whistle switch 111 that generates an ultrasonic wave that functions as a dog whistle is attached in the vicinity of the antenna 103 on the back side (back side) of the device main body 102 of the mobile phone 101. Further, in the vicinity of the dog whistle switch 111, a dog whistle output unit 112 for outputting the ultrasonic wave of the dog whistle from the inside of the apparatus main body 102 to the outside is disposed. The same control as when the dog whistle switch 111 is pressed may be performed by a combination of pressing keys (not shown) of the operation unit 107. When the dog whistle switch 111 and a key (not shown) of the operation unit 107 are pressed in combination, pressing the dog whistle switch 111 may be validated. This is to prevent inconvenience to a third party due to the dog whistle switch 111 being erroneously pressed.

  FIG. 3 shows a circuit configuration of the mobile phone according to the first embodiment. The cellular phone 101 includes a CPU (Central Processing Unit) 131 for various controls. The CPU 131 is connected to each unit via a bus 132 such as a data bus. Among these, the control program storage unit 133 is configured by a ROM (Read Only Memory) in which a control program for controlling each unit of the mobile phone 101 is stored. Of course, it may be constituted by other storage media. The work memory 134 is constituted by a RAM (Random Access Memory) that stores various data temporarily required when the CPU 131 executes the control program. The communication control unit 135 is a circuit part for performing communication control such as a call and detecting an incoming call by performing wireless communication with a wireless base station (not shown). The speaker 104 and the microphone 105 shown also in FIG. 1 are connected to the bus 132 via an output circuit or an input circuit such as an amplifier circuit (not shown). The display unit 106 and the operation unit 107 are also connected to the bus 132 via a display control circuit (not shown) or an operation key input circuit.

  The ultrasonic generator 137 is an apparatus that generates an ultrasonic wave corresponding to a dog whistle under a predetermined condition when the dog whistle switch 111 shown in FIG. 2 is pressed. The dog whistle generated by the ultrasonic generator 137 has a frequency of 12000 Hz to 30000 Hz, for example. The dog whistle having such a frequency does not need to be output continuously, and is output at a constant interval such as being output for 1 second and turned off for 3 seconds in order to suppress battery consumption (not shown) of the mobile phone 101. On / off may be repeated for a predetermined time.

  The emergency communication content storage unit 138 is a memory that stores content to be communicated in an emergency, and is configured by a nonvolatile memory. Two types of contents are stored here. One is an emergency voice message and its destination. The voice message may be prepared in advance by the manufacturer of the mobile phone 101 such as “Please help me”, or may be the content edited by the user himself using the microphone 105. The destination may be the phone number of a family member or close friend, but in the event of an earthquake or a traffic accident, the family member or close friend may be affected at the same time. Therefore, in this embodiment, two types of voice message transmission destinations are set. In other words, in addition to registering family and close friends as the first registration destination, register the police, local disaster relief center or fire department as the second registration destination, and the first registration destination cannot respond by voice Only occasionally, a voice message is transmitted to the second registration destination. By setting the two-stage transmission destination in this way, even when the dog whistle switch 111 is mistakenly pressed, it is possible to prevent the harmful effect that the public organization is confused by this. If the e-mail address is stored together with the telephone number, it is possible to correspond to e-mail transmission.

  When the family designated as the destination of the voice message is affected at the same time and the family responds, the caller can confirm the safety of the family. In that case, it is possible to request rescue from a public organization such as the police by further changing the transmission destination and making a call. If the family does not respond, a voice message is automatically sent to the two-stage destination, so that a rescue can be requested from a public organization such as the police at that time.

  FIG. 4 shows an outline of the control of the mobile phone when it becomes necessary to ask the user for help from another person. This will be described with reference to FIG. For example, when the user of the mobile phone 101 is confined or buried alive, the user presses the dog whistle switch 111 when seeking rescue. When the dog whistle switch 111 is pressed (step S201: Y), the CPU 131 checks the communication control unit 135 to determine whether communication with a radio base station (not shown) is impossible, that is, out of service ( Step S202). If it is not out of service area (N), the CPU 131 reads out the voice message and its transmission destination from the emergency communication content storage unit 138 (step S203), and performs outgoing call control (step S204).

FIG. 5 shows the specific contents of this transmission control. This will be described with reference to FIG. The CPU 131 controls the communication control unit 135 to transmit to the first registration destination (step S221). After the call processing, it is determined whether or not an incoming call is made with the registered partner within a predetermined time t ₁ (steps S222 and S223). If the incoming call is made (step S222: Y), a voice message is sent to the callee. It is output (step S224). Therefore, when the user of the mobile phone 101 is confined, the situation cannot be explained by voice, or the mobile phone 101 is moved close to the mouth due to the presence of an obstacle at the time of burying an earthquake or the like. Even in a situation where it is impossible, a preset voice message can be transmitted to the first registration destination. Thereafter, the display unit 106 displays that the contact by the voice message is successful (step S225), and the process is ended (END).

On the other hand, when the registration destination does not respond to the call within the predetermined time t ₁ (step S223: Y), the CPU 131 controls the communication control unit 135 to make a call to the second registration destination. (Step S226). If an incoming call is made (step S227: Y), a voice message is sent to the call destination (step S224). Subsequently, the display unit 106 displays that the contact by the voice message is successful (step S225), and the process is ended (END).

On the other hand, when the registration destination does not respond to the call within the predetermined time t ₂ (step S228: Y), the CPU 131 gives up outputting the voice message and contacts the display unit 106 with the voice message. Is displayed (step S229), and the process is terminated (END). The time t ₂ may be the same as the time t ₁ or may have a different time length.

Returning to FIG. 4, the description will be continued. When the transmission control as shown in FIG. 5 is performed in step S204, the dog whistle is output by the ultrasonic generator 137 by repeating the above-described on / off for a predetermined time (step S205). This dog whistle is output to the outside from the dog whistle output unit 112 shown in FIG. However, the sound of the dog whistle cannot be heard directly by humans. Therefore, during the time t ₃ when the dog whistle is sent out, the character display “During dog whistle output” is displayed on the display unit 106 (steps S205, S206, S207: N). When the time t ₃ is exceeded after the sending of the dog whistle is started (step S207: Y), all the processes are finished (end).

That is, when the user presses the dog whistle switch 111, it is within the range, and a pre-recorded voice message is transmitted to a pre-registered transmission destination, regardless of the success or failure of the transmission of this message. The dog whistle is output only for time t ₃ . Therefore, the location of the user seeking the rescue is limited to an area where the wireless base station can communicate as a result of communication between the mobile phone 101 possessed by the user and the wireless base station, and a dog such as a police dog by a dog whistle. It is possible to finally confirm the location by sensing the sound or using an ultrasonic receiver.

  Of course, if the mobile phone 101 of the embodiment uses a global positioning system such as GPS (Global Positioning System) or DGPS (Differential GPS), the detailed position of the user is communicated using the result of positioning by this. You can inform the other party. In particular, when the mobile phone 101 uses DGPS, it is possible to specify the position of the user within an error range of only a few meters.

On the other hand, if communication between the mobile phone 101 and the wireless base station is impossible (out of service area) in step S202 (Y), the process directly proceeds to step S205. Then, the dog whistle is output for the time t ₃ (step S205), and the character display “In dog whistle is being output” is displayed on the display unit 106 during that time (steps S206 and S207). Each time the user sees the display on the display unit 106 and the display of “outputting the dog whistle” disappears, or after a certain amount of time, the user presses the dog whistle switch 111 without blowing the actual dog whistle. You can repeat the ultrasonic transmission of the dog whistle. In addition, since it is determined in step S202 that the wireless base station is not in service, no power consumption required for wireless communication is required, and power can be effectively used for the output of the dog whistle.

  <Modification of the first embodiment>

  FIG. 6 shows an outline of the control of the mobile phone when the user needs to seek the rescue of another person in the modification of the first embodiment of the present invention. This will be described with reference to FIG. The same step numbers are assigned to the same parts as those in FIG. In this modification, in step S203A corresponding to step S203 in FIG. 4, the CPU 131 reads an e-mail message and its transmission destination from the emergency communication content storage unit 138. In step S204A corresponding to step S204, e-mail transmission control is executed.

  In the e-mail transmission control in step S204A, the e-mail may be simultaneously transmitted not only to the family and close friends, but also to the police, the local disaster relief center or the fire department. However, in this case, there is a possibility that a request for rescue is suddenly sent to a public organization such as the police due to a user's operation error. Therefore, in the body of the e-mail for family members and close friends, the e-mail was sent to the public authorities such as the police, and the telephone numbers of the contacts of these public institutions were recorded. It is preferable to write the telephone number of the contact information of the family or the like who sent the email at the same time in the body of the email. As a result, it is possible to prevent the public institution from being fooled by this when an email is transmitted due to some mistake. Of course, in the case of a person who becomes unclear due to an earthquake or confinement, it is natural that public institutions can take action immediately without checking with their family members.

  FIG. 7 shows the folded state of the cellular phone as the portable terminal device in the second embodiment of the present invention as seen from the back side. In the cellular phone 301, a generator / charger unit 304 is incorporated as an optional component on the back surface 303 side of the first housing 302 in a folded state, and in a case where the battery is normally stored. Yes. That is, a device part that is normally combined with a built-in battery and a back panel (not shown) constitutes a surface part by a part of the back panel 305 and the hand-powered power generation unit 306, and is slightly inside the remaining part of the hand-powered power generation unit 306. The apparatus has a configuration in which a small internal battery 307 is incorporated. The surface portion of the hand-powered power generation unit 306 includes a disk-shaped protrusion 306A and a hand-arm arm 308 in which the base 308A side is disposed in a groove 306B that bisects the protrusion 306A.

  A rotating shaft 309 is attached to the end of the hand turning arm 308 opposite to the base 308A side. When the generator / charger unit 304 is not used, the rotation is made in the notch 313 located at the end opposite to the hinge unit 312 that opens and closes the first housing 302 and the second housing 311. The shaft 309 is accommodated. As a result, when the cellular phone 301 is accommodated in or removed from a pocket such as a business suit, the hand turning arm 308 and the rotating shaft 309 are not caught in the pocket, and smooth processing is possible. In addition, since the generator / charger unit 304 is an optional part, a person carrying a spare battery pack does not use the generator / charger unit 304 as usual, but assigns it to the generator / charger unit 304. It is also possible to incorporate only the battery pack in the provided part.

  FIG. 8 shows a state in which charging by power generation is performed in the mobile phone of the second embodiment. When a user puts the tip of a finger (not shown) on the notch 313 and pulls up the side of the hand turning arm 308 with the rotation shaft 309 upward in FIG. 7, the base 308A rotates and the hand turning arm 308 is shown in FIG. Reversing from the state, the state shown in FIG. 8 is obtained. In this state, the user grasps the rotation shaft 309 with a finger and rotates it in the direction of the arrow 321 (clockwise). As a result, the manual power generation unit 306 rotates.

  The manual power generation unit 306 is configured by a flat motor, and rectifies the electromotive force obtained by the rotation to charge the built-in battery 307. The built-in battery 307 is relatively small, but the hand arm 308 can be rotated between calls or during a call. As a result, it is possible to prevent the battery from running out, or to easily secure the current power even when the battery runs out. Therefore, the mobile phone 301 can always be used when there is a situation where it is buried alive with a space around it or when it is isolated from the outside with a body moving, such as when confined in a room. Can be kept in a state.

  Since the cellular phone 301 of the second embodiment does not have the possibility of exhaustion of electric power as described above, a high-intensity light emitting diode 323 is incorporated at the tip of the antenna 322 as one means of using this electric power. Can be pointed as necessary. Thereby, the mobile phone 301 can be used as a flashlight in a dark place. The slide switch 324 is a switch for turning on the high brightness light emitting diode 323. In this embodiment, continuous lighting for about 60 seconds is possible by sliding the slide switch 324 once in the right direction. To extend the lighting, slide rightward. By sliding the slide switch 324 leftward, the high brightness light emitting diode 323 is immediately turned off.

  FIG. 9 shows an outline of the circuit configuration of the mobile phone according to the second embodiment. However, the same parts as those in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted as appropriate. The cellular phone 301 of the second embodiment is connected to the bus whistle switch 111, the ultrasonic generator 137, and the emergency communication content storage unit 138 in the same manner as the first embodiment, and a new slide switch. 324, a high-intensity light emitting diode lighting control circuit 331 and a power supply voltage display control circuit 332 are connected. Here, the high brightness light emitting diode lighting control circuit 331 is connected to the high brightness light emitting diode 323. In addition, a generator / charger unit 304 is connected to the power supply voltage display control circuit 332 so that the display unit 106 is controlled to display the output voltage of the built-in battery 307 to be charged. .

  The control program storage unit 133A shown in FIG. 9 stores a control program for controlling each part of the mobile phone 301 of the second embodiment, which has more functions than the mobile phone 101 of the first embodiment. . However, since the control of the cellular phone by operating the dog whistle switch 111 is as described with reference to FIGS. 4 to 6, the description thereof is omitted.

  FIG. 10 shows an outline of display control of the power supply voltage display control circuit. The power supply voltage display control circuit 332 checks the output voltage of the built-in battery 307 via the generator / charger unit 304 shown in FIGS. 7 to 9 (step S401). Then, the detected output voltage is collated with a plurality of predetermined voltage ranges, thereby reflecting the current output voltage state on the battery mark displayed on the display unit 106 (step S402). For example, the remaining amount of the built-in battery 307 is displayed by changing the number of bar lines marked in the battery-shaped mark according to the output voltage.

Next, the power supply voltage display control circuit 332 determines whether or not the detected output voltage of the internal battery 307 is less than the voltage _VL corresponding to the upper limit value (highest voltage) at the lowest stage (step S403). If so, the power generation / charge warning display is displayed in a conspicuous color such as red on the display unit 106 (step S404). For example, a message “Please generate or charge” is displayed on the display unit 106. When a charger (not shown) is nearby, the user can use this to perform charging. When the charger is not nearby or when the set is troublesome, charging can be easily performed by turning the hand-turning arm 308 as shown in FIG.

  Therefore, if there is a situation where the body is alive and buried in a state where the surrounding space is secured or the body is moving and isolated from the outside, such as when confined in the room, the internal battery 307 is concerned about the exhaustion. It is possible to repeatedly issue a request for rescue to the outside with a dog whistle or the like. Further, the high-intensity light-emitting diode 323 at the tip of the antenna 322 can be easily used as a flashlight in a dark place such as a night road.

  Of course, the mobile phone 301 according to the second embodiment did not have a function as a television or a radio. However, when the mobile terminal device has these functions, the mobile phone 301 does not have to worry about the depletion of the battery. These functions can be actively used to gather external information. Therefore, the present invention has the advantage that the functions of the television and GPS can be utilized to the fullest without worrying about the consumption of the battery, not only in the case of an emergency requesting the assistance of another person but also in the normal time.
