  Embodiments according to the present invention will be described below with reference to the drawings. In addition, the structure which attached | subjected the same code | symbol in each figure shows that it is the same structure, The description is abbreviate | omitted.

  FIG. 1 is a block diagram showing an example of a configuration of an emergency call device using an emergency call method according to an embodiment of the present invention. An emergency call device 1 shown in FIG. 1 is configured as, for example, a mobile phone terminal device that can be easily carried by a user, and includes an antenna 2, a radio circuit unit 3 (wireless communication unit), a reception level measurement unit 4, and a report destination storage unit 5. , A control unit 6, a microphone 7 (audio acquisition unit), a speaker 8 (audio output unit), an audio monitor setting button 9, an emergency notification button 10, an automatic notification setting button 11, and a keyboard 12.

  The antenna 2 receives a radio signal transmitted from a radio base station. The radio circuit unit 3 demodulates a radio signal received by the antenna 2 and outputs the demodulated signal to the control unit 6, or modulates a signal output from the control unit 6 and transmits the signal from the antenna 2 as a radio signal. The radio signal received by the antenna 2 is output from the radio circuit unit 3 to the reception level measurement unit 4. The reception level measurement unit 4 measures the signal level of the radio signal received by the antenna 2 and outputs a signal indicating the signal level to the control unit 6.

  The microphone 7 acquires sound, generates a sound signal indicating the acquired sound, and outputs the sound signal to the control unit 6. The speaker 8 is an audio output unit that outputs audio based on a radio signal received from the radio base station by the radio circuit unit 3, and is connected to the control unit 6 via the switch SW1.

  The voice monitor setting button 9, the emergency notification button 10, the automatic notification setting button 11, and the keyboard 12 are operation switches that receive a user operation instruction and output a signal indicating the operation instruction to the control unit 6. The voice monitor setting button 9 is a switch for setting whether to enable or disable a voice monitor function to be described later. For example, a toggle switch is used. The emergency call button 10 is a switch for manually making an emergency call. The automatic notification setting button 11 is a switch for setting whether to enable or disable an automatic emergency call function, which will be described later. For example, a toggle switch is used. The keyboard 12 is used to input an emergency call destination telephone number, an e-mail address, and other operation instructions.

  The control unit 6 includes, for example, a CPU (Central Processing Unit) that executes predetermined arithmetic processing, a ROM (Read Only Memory) that stores a predetermined control program, and a RAM (Random Access Memory) that temporarily stores data. And a peripheral circuit and the like, and by executing a control program stored in the ROM, an audio signal transmission control unit 601, an audio output control unit 602, a notification processing control unit 603, a fading pitch detection unit 604, a moving speed acquisition unit 605, an emergency detection unit 606, a notification processing unit 607, and a notification destination setting processing unit 608 function.

  The fading pitch detection unit 604 detects the fading pitch from the signal level measured by the reception level measurement unit 4. Specifically, for example, the fading pitch detection unit 604 changes the signal level measured by the reception level measurement unit 4 using a bandpass filter that passes a signal level fluctuation frequency due to fading, for example, a frequency of about 1 Hz to 100 Hz. The fading pitch L is detected by taking out the frequency component resulting from fading as a fading frequency f and measuring the fading frequency f, that is, the reciprocal of the fading pitch.

  The movement speed acquisition unit 605 acquires the movement speed of the emergency call device 1 from the fading frequency f (reciprocal of the fading pitch L) detected by the fading pitch detection unit 604 and outputs the movement speed to the control unit 6. Specifically, for example, a LUT (Look Up Table) in which the relationship between the fading frequency f and the moving speed is associated in advance is stored in the ROM, and the moving speed acquisition unit 605 refers to the LUT so that fading is performed. The moving speed of the emergency call device 1 is acquired from the fading frequency f detected by the pitch detection unit 604.

  The emergency state detection unit 606 determines that an emergency has occurred when the movement speed detected by the movement speed acquisition unit 605 exceeds a preset threshold value Vth. In this case, the threshold value Vth is set to a speed that exceeds a user's assumed moving speed. For example, a speed at which a child may be taken by a transportation such as a car or a train for the purpose of kidnapping, for example, 40 km / h. Is preset. In addition, since the speed at which a person walks is generally considered to be 10 km / h or less, the threshold Vth is set to a value exceeding 10 km / h, for example, 15 km / h, and when moving by a method other than walking. It may be determined that an emergency has occurred.

  The report destination setting processing unit 608 displays a report destination for reporting the occurrence of an emergency when the emergency detection unit 606 determines that an emergency has occurred, for example, a contact number such as a telephone number or an e-mail address. Is received and stored in the report destination storage unit 5.

  The notification destination storage unit 5 is configured using, for example, an EEPROM (Electrically Erasable and Programmable Read Only Memory) which is a rewritable nonvolatile memory, and when the emergency detection unit 606 determines that an emergency has occurred In addition, information on a notification destination to be notified by wireless communication, such as a telephone number or an e-mail address, is stored in advance.

  When the emergency detection unit 606 determines that an emergency has occurred, the notification processing unit 607 causes the radio circuit unit 3 to transmit an emergency notification signal indicating the occurrence of the emergency from the antenna 2 to the radio base station.

  When the emergency detection unit 606 determines that an emergency has occurred, the audio signal transmission control unit 601 causes the radio circuit unit 3 to transmit the audio signal output from the microphone 7 from the antenna 2 to the radio base station. The audio output control unit 602 outputs an audio signal indicating audio to the speaker 8 based on the radio signal received from the radio base station by the radio circuit unit 3 and causes the speaker 8 to output audio. In addition, when the emergency detection unit 606 determines that an emergency has occurred, the audio output control unit 602 turns off the switch SW1 and prohibits the speaker 8 from outputting audio. As a result, a voice monitoring function is executed to prohibit voice output from the speaker 8 for the voice signal transmitted from the emergency call destination while transmitting the voice signal acquired by the microphone 7 to the emergency call destination.

  For example, when the emergency notification button 10 is pressed, the notification processing control unit 603 causes the notification processing unit 607 to transmit an emergency notification signal to the notification destination stored in the notification destination storage unit 5. The notification processing control unit 603 determines that an emergency has occurred by the emergency detection unit 606 when, for example, the automatic notification setting button 11 is turned on in response to an operation instruction received by the automatic notification setting button 11. In this case, the notification processing unit 607 causes the automatic emergency notification function to transmit an emergency notification signal indicating the occurrence of an emergency. On the other hand, for example, when the automatic notification setting button 11 is turned off, the notification processing control unit 603 prohibits the operation of the automatic emergency notification function.

  Next, operation | movement of the emergency call apparatus 1 comprised as mentioned above is demonstrated. FIG. 2 is a block diagram for explaining the operation of the emergency call device 1. An emergency call device 1 shown in FIG. 2 is, for example, a PDC (Personal Digital Cellular) mobile phone terminal device, and is configured to perform wireless communication with a PDC base station 21 (wireless station). The PDC base station 21 is connected to a center station 23 that is an emergency call destination via a public line network 22 such as a telephone line or the Internet. The center station 23 is, for example, a security company management center, the police, a user's home, or the like. Thus, the PDC base station 21 can communicate with the center station 23 via the PDC base station 21 and the public line network 22.

  FIG. 3 is a flowchart showing an example of the operation of the emergency call apparatus 1 shown in FIG. First, the user uses the keyboard 12 to input the telephone number and e-mail address of the center station 23 that is the emergency call destination. Then, the telephone number and the e-mail address accepted by the keyboard 12 are stored in the report destination storage unit 5 by the report destination setting processing unit 608 (step S1). Accordingly, the user can set the telephone number and e-mail address of the emergency call destination using the keyboard 12, so that the user is not limited to the center station 23, for example, a fixed telephone at home, a predetermined mobile phone, etc. The telephone number of the emergency call destination can be set or changed accordingly.

  Next, the voice output control unit 602 performs voice monitor function setting processing (step S2). Specifically, for example, when the sound monitor setting button 9 is turned on, the sound output control unit 602 turns off the switch SW1 to enable the sound monitor function, and the sound output from the speaker 8 is prohibited. For example, when the sound monitor setting button 9 is turned off, the sound output control unit 602 turns on the switch SW1 to disable the sound monitor function, and the prohibition of sound output by the speaker 8 is released.

  Note that the audio output control unit 602 may be configured to perform the setting process of the audio monitor function according to a control signal transmitted from the center station 23 via the public network 22 and the PDC base station 21, for example.

  Next, the notification processing control unit 603 confirms whether or not the emergency call button 10 has been pressed (step S3). If the emergency call button 10 has been pressed, the process proceeds to step S7 to make an emergency call. (YES in step S3) If the emergency call button 10 is not pressed, the process proceeds to step S4 to set whether to enable or disable the automatic emergency call function (NO in step S3). Thereby, when the user wants to make an emergency call intentionally, the emergency call can be made promptly by pressing the emergency call button 10.

  Next, in step S4, the notification processing control unit 603 checks whether or not the automatic notification setting button 11 is turned on (step S4), and the automatic notification setting button 11 is turned on and the automatic emergency notification function is set to be valid. If YES (YES in step S4), the process proceeds to step S5 to perform automatic detection processing of an emergency, while the automatic notification setting button 11 is turned off and the automatic emergency notification function is disabled. (NO in step S4), the process proceeds to step S2 and steps S2 to S4 are repeated. Thereby, for example, when the user carries the emergency call device 1 and goes out on a car or train, when it is known in advance that the moving speed V of the emergency call device 1 exceeds the threshold value Vth, the automatic notification setting is performed. By keeping the button 11 off, it is possible to avoid making an emergency call due to movement by a normal car or train.

  FIG. 4 is a flowchart showing an example of details of the emergency automatic detection process in step S5. First, a radio signal transmitted from the PDC base station 21 is received by the antenna 2, amplified by the radio circuit unit 3, and then output to the reception level measurement unit 4, and the signal level of the radio signal is received by the reception level measurement unit 4. Are measured, and the measured signal level is output to the fading pitch detector 604.

  FIG. 5A shows the signal level when the radio signal transmitted from the PDC base station 21 is received by the emergency call device 1 when the emergency call device 1 does not move, that is, measured by the reception level measuring unit 4. It is a graph which shows an example of a signal level. As shown in FIG. 5A, when the emergency call device 1 does not move, the reception level received by the emergency call device 1 hardly fluctuates.

  On the other hand, FIG. 5 (b) shows that the radio signal transmitted from the PDC base station 21 when the user carrying the emergency call device 1 is taken and moved, for example, by being kidnapped, is an emergency call device. 2 is a graph showing an example of a signal level when received by 1, that is, a reception level measured by a reception level measuring unit 4. As shown in FIG. 5B, when the emergency call device 1 is moving, the reception level fluctuates due to fading.

  It is known that the fluctuation of the reception level due to fading has periodicity. In FIG. 5B, the interval between valleys in the fluctuation of the reception level due to fading is the fading pitch L, and the reciprocal of the fading pitch L. Is a fading frequency f, it is known that there is a correlation between the fading frequency f and the moving speed V of the emergency call device 1.

For example, the interval between valleys in the variation of the reception level varies slightly, such as L ₁ , L ₂ , L ₃ , and L ₄ as shown in FIG. L ₁ , L ₂ , L ₃ , and L ₄ have a relationship of L ₁ ≈L ₂ ≈L ₃ ≈L ₄ , and L ₁ , L ₂ , L ₃ , and L ₄ may be directly used as the fading pitch L. For example, The fading pitch L may be an average value of intervals between a plurality of valleys, for example, an average value of L ₁ , L ₂ , L ₃ , and L ₄ may be a fading pitch L.

  Therefore, the fading pitch detection unit 604 measures the fading pitch L based on the signal level measured by the reception level measurement unit 4 to calculate the moving speed of the emergency call device 1 based on the fading frequency f, and calculates the reciprocal thereof. Then, the fading frequency f is measured and output to the moving speed acquisition unit 605 (step S101).

  Next, the moving speed acquisition unit 605 calculates the moving speed of the emergency call device 1 from the fading frequency f acquired by the fading pitch detection unit 604. FIG. 6 is an explanatory diagram in a tabular format showing an example of the correspondence relationship between the fading frequency f and the moving speed V of the emergency call device 1. As shown in FIG. 6, when the fading frequency f is fp or less, the moving speed V is 10 km / h or less, and when the fading frequency f is fp to 2 fp, the moving speed V is 10 km / h to 20 km / h, and the fading frequency f is 2 fp to If it is 3 fps, the moving speed V is 20 km / h to 30 km / h, and if the fading frequency f is 3 fps to 4 fp, the moving speed V is 30 km / h to 40 km / h, and if the fading frequency f is 4 fps or more, the moving speed V is 40 km / h or more. In this way, a proportional relationship is established between the fading frequency f and the moving speed V. For example, if the fading frequency f is 40 Hz, the moving speed V is 50 km / h, and if the fading frequency f is 80 Hz, the moving speed V is 100 km / h.

  Therefore, the moving speed acquisition unit 605 refers to, for example, the LUT indicating the correspondence between the fading frequency f and the moving speed V of the emergency call device 1 as described above, and from the fading frequency f acquired by the fading pitch detection unit 604. The moving speed V of the emergency call device 1 is calculated (step S102).

  Next, the emergency detection unit 606 compares the moving speed V calculated in step S102 with a preset threshold value Vth (step S103), and if the moving speed V is equal to or lower than the threshold value Vth (NO in step S103). ) It is determined that no emergency has occurred (step S104). On the other hand, if the moving speed V exceeds the threshold value Vth (YES in step S103), the duration T during which the moving speed V exceeds the threshold value Vth is measured using a timer circuit (not shown), for example (step S105). Then, the emergency state detection unit 606 checks whether or not the duration T exceeds a preset time Tth (step S105). If the duration T is less than the set time Tth (NO in step S105), the process proceeds to step S101 and the processes in steps S101 to S105 are repeated again. On the other hand, if the duration T reaches the set time Tth (step It is determined that an emergency has occurred (step S106), and the process proceeds to step S6.

  In this case, even if the moving speed V exceeds the threshold value Vth, if the duration T is less than the set time Tth, it is not determined that an emergency has occurred. For example, the moving speed may vary due to fading pitch variations or noise due to disturbance. When the calculated value of the moving speed V by the acquisition unit 605 exceeds the threshold value Vth, it is possible to reduce an accidental emergency call.

  If the emergency detection unit 606 determines that no emergency has occurred (NO in step S6), the process proceeds to step S2 and repeats steps S2 to S6 again, while an emergency has occurred. (YES in step S6), the process proceeds to step S7 to make an emergency call.

  Next, in step S7, the telephone number of the emergency report destination is read from the report destination storage section 5 by the report processing section 607, the radio circuit section 3 designates the telephone number as the destination, and the PDC base from the antenna 2 An emergency notification signal indicating the occurrence of an emergency situation is transmitted to the center station 23 via the station 21 and the public line network 22 (step S7). In this case, the emergency notification signal may be, for example, a notification of the occurrence of an emergency by arriving at the telephone of the center station 23, for example, a notification of the occurrence of an emergency by voice. Alternatively, the occurrence of an emergency situation may be notified using a DTMF (Dual Tone Multi-Frequency) signal.

  As described above, when the moving speed V of the emergency call device 1 reaches the moving speed of the transportation facility by the processing of steps S1 to S7, it can be determined that an emergency has occurred and an emergency call can be made. When a user who should not use is taken away using transportation, an emergency call can be made without the user performing an operation.

  Further, the e-mail address of the emergency call destination is read from the call destination storage unit 5 by the report processing unit 607, and the e-mail address is designated as the destination by the radio circuit unit 3 from the antenna 2 to the PDC base station 21 and Emergency call information indicating the occurrence of an emergency situation is transmitted to the center station 23 via the public network 22 (step S8). The emergency call information may include various information such as information indicating the current position of the emergency call device 1 obtained using a GPS (Global Positioning System) receiver, for example. Further, the emergency call information is not limited to electronic mail, and may be transmitted to the emergency call destination by other data communication such as packet communication.

  Thus, when it is determined that an emergency has occurred, detailed information such as current location information can be transmitted to the emergency call destination using data communication. In addition, if a plurality of communication addresses such as an e-mail address of an emergency call destination are stored in the report destination storage unit 5, an emergency call can be made to a plurality of emergency call destinations by e-mail or data communication in a short time. .

  Next, the switch SW1 is turned off by the sound output control unit 602, and sound output from the speaker 8 is prohibited (step S9).

  Next, the audio signal acquired by the microphone 7 is output to the radio circuit unit 3 in accordance with the control signal from the audio signal transmission control unit 601. Then, the audio signal is transmitted as a radio signal from the antenna 2 to the PDC base station 21 by the radio circuit unit 3, and is transmitted from the PDC base station 21 to the center station 23 via the public line network 22 (step S10).

  As described above, when it is determined by the processes in steps S9 and S10 that an emergency has occurred, the voice acquired by the microphone 7 by voice communication is transmitted to the emergency call destination. The sound around 1 can be monitored, that is, for example, it is easy to check the situation of the kidnapping site when the user is kidnapped, or to obtain information on the safety information of the user, the destination, etc. It becomes.

  Further, when it is determined that an emergency has occurred, the switch SW1 is turned off and the sound output from the speaker 8 is prohibited. For example, when the sound is output from the emergency notification device 1, the emergency notification device The emergency call device 1 is found by a person in the vicinity of the user carrying the phone 1, for example, a criminal who takes the user carrying the emergency call device 1 for the purpose of kidnapping, etc., and the emergency call is stopped. Can be avoided.

  When the user wants to make a voice call with the center station 23, for example, the voice output control unit 602 sets the voice monitor function to be invalid by turning off the voice monitor setting button 9. Accordingly, the switch SW1 is turned on, the audio signal transmitted from the center station 23 is output to the speaker 8, and the speaker 8 performs audio output, so that the user makes a two-way audio call with the center station 23. It can be carried out.

  In the center station 23, for example, when the voice around the emergency call device 1 is monitored by the voice monitor function, there is a case where it is desired to output the voice from the emergency call device 1 depending on the situation. In such a case, a control signal for invalidating the voice monitoring function is transmitted from the center station 23 to the emergency call apparatus 1 through the public network 22 and the PDC base station 21 by data communication, and the voice output control unit 602 The switch SW1 may be turned on.

  Alternatively, in the center station 23, when it is known that the user intentionally moves by transportation, the center station 23 sends the data to the emergency call device 1 via the public network 22 and the PDC base station 21. Alternatively, a control signal for disabling the automatic emergency call function may be transmitted so that an emergency call is not made even if the user moves by transportation.

  In addition, for example, the control signal using the DTMF signal is transmitted from the center station 23 to the emergency call device 1 via the public network 22 and the PDC base station 21 so that the operation of the emergency call device 1 is remotely controlled. It may be. For example, as shown in FIG. 7, when “10” is transmitted by the DTMF signal from the center station 23 to the emergency call device 1, the automatic emergency call function is set to be effective by the call processing control unit 603, and the DTMF signal is set. When “11” is transmitted, the automatic emergency call function is disabled by the message processing control unit 603, and when “20” is transmitted by the DTMF signal, the voice output control unit 602 sets the voice monitor function. When “21” is transmitted by the DTMF signal, the audio monitor function may be set to be invalid by the audio output control unit 602.

  Thereby, the operation of the emergency call device 1 can be set from the remote center station 23. For example, the child carrying the emergency call device 1 is a voice monitor setting button 9 or an automatic call setting button. Even when 11 cannot be operated appropriately, various function settings in the emergency call device 1 such as a voice monitor function and an automatic emergency call function can be performed from the remote center station 23. In addition, if the operation of the emergency call device 1 is remotely controlled using the DTMF signal, the voice monitoring function, the automatic emergency call function, etc., while performing voice communication between the emergency call device 1 and the center station 23, Various function settings in the emergency call device 1 can be performed.

  Further, by adopting a public wireless communication system, for example, a PDC system, as the radio system of the emergency call apparatus 1, the area where the emergency call apparatus 1 can make an emergency call is equal to a service area such as a mobile phone, and a service area such as a mobile phone. You can make emergency calls from anywhere.

  Further, if the telephone number of the emergency call destination is stored in advance in the report destination storage unit 5, the emergency call device 1, that is, the user of the device, can make an emergency call without being aware of the telephone number of the emergency call destination. Sometimes emergency calls can be made to the phone number. For example, an operator operating a business that provides an emergency call device 1 to a user and provides various services in response to an emergency call from the emergency call device 1, for example, a security company, calls a phone number that is desired to be an emergency call destination. If the emergency call device 1 is provided to the user by being stored in the storage unit 5 in advance, the user need not be aware of the telephone number of the emergency call destination.

  In addition, although the example where the emergency call destination is the center station 23 such as a security company has been shown, for example, as shown in FIG. 8, for example, the telephone number of the fixed telephone 24 at the user's home connected to the public network 22 By storing the telephone number and e-mail address of the mobile phone terminal device 25 in the report destination storage unit 5 as an emergency call destination, the fixed telephone 24 may be used as an emergency contact address or the mobile phone terminal device 25 as an emergency call destination. The emergency call device 1 may make an emergency call by voice signal or data communication to the mobile phone terminal device 25 via the PDC base station 21, the public line network 22, and the mobile phone base station 26.

  Further, the emergency call device 1 is not limited to a PDC mobile phone terminal device, but may be another communication method. Furthermore, the emergency call apparatus 1 should just be able to perform radio | wireless communication, and may not be a mobile telephone terminal device. For example, as shown in FIG. 9, the radio station is the emergency call destination 21a, and the telephone number and e-mail address of the mobile phone terminal device 25, the e-mail address of the personal computer 28 connected to the Internet 27, etc. By storing the emergency call destination in the call destination storage unit 5, the emergency call device 1 makes an emergency call to the emergency call destination 21 a by wireless communication using a preset communication frequency and communication address, and the emergency call destination. An emergency call is made by e-mail to the personal computer 28 connected to the Internet 27 via the Internet 27 connected to 21a, or the Internet 27, the public network 22 and the mobile phone base station connected to the emergency call destination 21a 26 to the mobile phone terminal device 25 by voice signal or data communication. It may be or perform sudden report.
