  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing a first embodiment of a portable wireless communication terminal according to the present invention, wherein 9a is a mail processing unit, 9b is a voiceprint / voice recognition unit, 11a is a keyword / execution processing storage unit, Is a weak voice signal detection unit, and parts corresponding to those in FIG.

  In the figure, a microphone 7 is connected to a sound processing unit 6 via a weak sound signal detection unit 12, and a sound signal from the microphone 7 is amplified to a desired level by the weak sound signal detection unit 12. 6 is supplied. The weak sound signal detection unit 12 performs a function of detecting a weak sound signal from the microphone 7 and amplifying it to a desired level (hereinafter referred to as a weak signal amplification function) in a notification mode to be described later. In a call mode in which a call is made with the other party, a weak signal from the microphone 7 is cut as noise, and a function for amplifying a voice signal due to the call (hereinafter referred to as a normal amplification function) is executed.

  The call mode is set by a predetermined key input at the key input unit 10, and the call mode is automatically set when the call mode or the like ends and the portable wireless communication terminal is not used.

  In a call mode in which the key input unit 10 is operated to perform a normal call (outgoing / incoming) process, the weak voice signal detection unit 12 is in a state of executing a normal amplification function, and an input voice signal from the microphone 7 is set. Is amplified by the weak voice signal detection unit 12 and supplied to the voice processing unit 6 to perform a normal call. In addition, when a call termination operation is performed with the key input unit 10, a notification mode capable of automatically reporting such as an emergency call is set, and the weak voice signal detection unit 12 enters a state in which the weak signal amplification function is activated, A weak audio signal from the microphone 7 is detected, amplified, and supplied to the audio processing unit 6. Such control is performed by the control unit 9 in accordance with the operation of the key input unit 10.

  That is, the control unit 9 is configured so that the microphone 7 and the voice processing unit 6 are connected via the weak voice signal detection unit 12 (weak signal amplification function) in the notification mode other than the call mode during the call processing. Control.

  Here, an emergency call mode for making an emergency call is also set by a predetermined key operation of the key input unit 10, and as with the prior art, by reporting to a service center 206 such as a security company with location information. Then, an emergency call can be made to the portable radio communication terminal of the reporting partner by sending a map mapping the current position of the portable radio communication terminal. In this case, when a mail message for such an emergency call is registered in the memory 11, this mail message is processed by the mail processing when the mail message is input from the key input unit 10. An e-mail is processed by the unit 9a, and the mobile phone of the emergency call destination (the other party) whose e-mail address is registered in the memory 11 from the cellular phone antenna 2 via the signal processing unit 5 and the radio unit 3 It is transmitted to the wireless communication terminal using this mail address. In this case, a plurality of portable wireless communication terminals on the other side can be used.

  When the operation for ending the call mode is performed at the key input unit 10, the mode becomes a notification mode for notification such as an emergency call, and the weak voice signal detection unit 12 automatically enters the operating state of the weak signal amplification function. For this reason, the weak voice signal detection unit 12 may change its function between the call mode and the notification mode as described above, or the control unit 9 may replace the microphone 7 with the voice processing unit. Alternatively, the route directly connecting to the microphone 6 and the route connecting the microphone 7 to the sound processing unit 6 may be switched via the weak sound signal detection unit 12 in which the weak signal amplification function is always set.

  Such a modification of the first embodiment is shown in FIG. In FIG. 2, reference numeral 13 denotes a changeover switch, and reference numerals 14a and 14b denote paths. The parts corresponding to those in FIG.

  In the figure, a changeover switch 13 is provided between the microphone 7 and the weak sound signal detection unit 12, and the first from the microphone 7 to the sound processing unit 6 via the changeover switch 13 and the weak sound signal detection unit 12. Path 14a and a second path 14b from the microphone 7 via the changeover switch 13 to the sound processing unit 6 are formed. Here, the weak sound signal detection unit 12 has only a weak signal amplification function.

  The change-over switch 13 is switch-controlled by the control unit 9, and in the notification mode, the change-over switch 13 is closed to the weak audio signal detection unit 12 side in order to detect a weak notification signal. When the path 14a is established and the call mode is set, the changeover switch 13 is closed to the voice processing unit 6 side to establish the first path 14a, and the voice signal of the call from the microphone 7 is directly supplied to the voice processing unit 6.

  As another modification, the changeover switch 13 is provided between the weak sound signal detection unit 12 and the sound processing unit 6, and the changeover switch 13 detects the sound signal from the microphone 7 in the notification mode. The voice signal from the microphone 7 is routed through the selector switch 13 while avoiding the weak voice signal detector 12 during the call mode and the path supplied to the voice processor 6 via the unit 12 and the selector switch 13. Thus, a route supplied to the voice processing unit 6 may be established.

  Below, although 1st Embodiment shown in FIG. 1 is described, it is the same also about said modification.

  When the call mode is not set and the portable wireless communication terminal is not used for a call, the portable wireless communication terminal is stored in a user's bag or the like. At this time, the portable wireless communication terminal is in the notification mode, and the weak voice signal detection unit 12 is in the active state of the weak signal amplification function (in the modification shown in FIG. 2, the first path 14a is established). ) In such a situation, when an emergency situation or situation requiring contact with the other party occurs, it becomes necessary for the user to report to another portable wireless communication terminal. When it is set, if the user speaks a predetermined keyword for notification, the microphone 7 is separated from the user's mouth, but the voice of this keyword is read by the microphone 7 as a weak voice signal, The audio signal (hereinafter referred to as a notification audio signal) is amplified by the weak audio signal detection unit 12 and supplied to the audio processing unit 6, where predetermined processing is performed and then supplied to the control unit 9.

  The control unit 9 includes a mail processing unit 9a and a voiceprint / speech recognition unit 9b, which are set in an operating state. The mail processing unit 9a performs processing for mail transmission, and the voiceprint / speech recognition unit 9b operates in the report mode and is registered in the voiceprint in the report voice signal and the voiceprint / speech recognition unit 9b. Comparison with the user's voiceprint (voiceprint recognition) is performed to determine whether or not the report is made by the user. When the user's voiceprint is recognized, a keyword to be described later is recognized. Voice recognition is also performed.

  Further, the memory 11 stores information such as user data such as a local station address, a telephone number of a mobile phone of another user, a mail address of a report destination, a mail message used in a report mode, and a keyword / execution. A processing storage area 11a is provided in which keywords for various notifications such as emergency notifications and data of execution processing contents corresponding to the respective keywords are stored. Note that the number of destinations for emergency calls and contact notifications may be two or more. In this case, each mail address is registered in the memory 11.

  As keywords, for emergencies, words such as “scary” and “dangerous” are usually used in an unconscious manner when an emergency occurs. In addition, there are cases where you want to notify the other party without any hassle for making a call, such as informing your family about where you are, for example (notifying the contact). Keywords can be set. As an example of a keyword for such a situation, for example, a keyword such as “Arrive” or “Let's go home” can be used to inform the family of where to go when arriving at the destination or where to return. .

  Further, execution processing contents are set for such keywords, and the execution processing contents are processing means such as software for performing data processing necessary for emergency notification or notification notification. .

  Further, some keywords are assigned mail messages to be sent to the reporting partner, and such mail messages are also stored in the memory 11 as described above.

  Note that the key input unit 10 can additionally register information such as the above-described keywords and mail addresses in the memory 11, and can also change or modify already registered information.

  Therefore, when the notification voice signal processed by the voice processing unit 6 is supplied to the control unit 9 as described above in the emergency call mode or the contact notification mode, the control unit 9 causes the voice print / voice recognition unit 9b to Then, the voice print is recognized by comparing the voice print with the registered user's voice print from the report voice signal. When the voiceprint of the report voice signal substantially matches the registered user's voiceprint, the control unit 9 determines that the report is from the user of the portable wireless communication terminal that makes this emergency call (that is, the reporter). The speech recognition processing is performed, and the keyword stored in the keyword / execution processing content storage unit 11a is searched based on the recognition result. When the report voice signal is not a keyword, there is no keyword that matches the voice recognition result, but when a keyword that matches the voice recognition result is searched, it is stored in the keyword / execution processing content storage unit 11a. The execution process contents corresponding to the searched keyword are searched from the execution process contents being executed.

  And the control part 9 performs the control process for emergency call mode or contact notification mode based on this execution process content. In this control process, the control unit 9 reads the mail address of the other party (report destination) to be notified from the memory 11 and the mail address of the own station (the portable wireless communication terminal on the notification side to make an emergency call), and the GPS satellite 207. The position information representing the current position of the portable wireless communication terminal from (FIG. 10) is acquired from the position information detection unit 4. These e-mail addresses and position information are transmitted from the cellular phone antenna 2 to the service center 206 (FIG. 10) such as a security company through the signal processing unit 5 and the radio unit 3 under the control of the control unit 9. . This position information is repeatedly transmitted to the service center 206 every time it is acquired from the GPS satellite 207 from the position information detection unit 4. The service center 206 maps the current position on the map based on the position information indicating the current position of the own station, that is, the portable wireless communication terminal on the reporting side, as in the prior art. The map information is transmitted to the portable radio communication terminal of the report partner of the mail address acquired from the portable radio communication terminal on the reporting side, and an emergency call is made.

  At the same time, if the mail message corresponding to the keyword at this time is stored in the memory 11, the control unit 9 obtains the mail message and processes it by the mail processing unit 9a to create an emergency call e-mail. . Such an emergency call e-mail is sent from the mobile phone antenna 2 via the signal processing unit 5 and the radio unit 3 under the control of the control unit 9 to the portable type of the other party's e-mail address corresponding to the keyword at this time. It is transmitted to the wireless communication terminal.

  As a result, the portable wireless communication terminal of the reporting partner displays the current location of the reporting portable wireless communication terminal on the map and simultaneously displays the notification mail. In addition, this map showing the current location represents the current location that is sometimes sent from the reporting portable radio communication terminal, so even if the reporting portable radio communication terminal moves, the report is sent. The user of the receiving portable wireless communication terminal can always know the current position of the user of the reporting portable wireless communication terminal.

  In this way, in this first embodiment, since an emergency call can be made without direct operation by the user, the portable wireless communication terminal is placed in a bag or the like when a call is required. Thus, even when the user cannot directly operate the portable wireless communication terminal, it is possible to make an emergency call or contact notification to the desired portable wireless communication terminal.

  FIG. 3 is a flowchart showing the movement operation of the first embodiment.

  In the figure, when there is no operation of the emergency call key at the key input unit 10 ("N" in step S200), and when it is not in the notification mode (that is, not in the emergency call mode or the contact notification mode), steps S200 and S201 are performed. This determination procedure is repeated, and the notification is in a standby state.

  In this standby state, when an emergency key is operated on the key input unit 10 (“Y” in step S200), an emergency call is sent to the service center 206 (FIG. 10) and the GPS satellite 207 acquired from the position information detection unit 4 is sent. Each time the position information from FIG. 10 is acquired, an emergency call is transmitted to the service center 206. The service center 206 transmits a map mapping the current position based on the position information to one or more portable wireless communication terminals on the other party side together with an emergency call (step S206). If there is a mail message, the mail message is transmitted as an e-mail to the portable radio communication terminal on the other side (step S207).

  When in the notification mode (“N” in step S200, “Y” in step S201), the audio signal based on the input weak audio signal of the microphone 7 detected by the control unit 9 from the audio processing unit 6 to the weak audio signal detection unit 12 (“Y” in step S202), the voiceprint / speech recognition unit 9b performs voiceprint recognition by comparing the voiceprint of this voice signal with the registered voiceprint (step S203). Sometimes ("N" in step S204), it is determined that it is not by the user of this portable wireless communication terminal, and the process returns to step S200.

  When the voiceprint of the voice signal substantially matches the registered voiceprint (“Y” in step S204), it is determined that the voice signal is from the user of the portable wireless communication terminal, and the voiceprint / voice recognition unit Voice recognition is performed in 9b, a keyword registered in the keyword / execution processing storage unit 11a of the memory 11 is searched based on the recognition result, and if there is an emergency call keyword matching the recognition result (step S205). "Y"), the execution process content corresponding to this keyword is read, and this is executed and the position information from the GPS satellite 207 is received every time the position information is detected from the position information detector 4, and the The emergency call is transmitted from the unit 3 to the service center 206 (step S206). In the service center 206, as described above, a map in which the current location of the portable wireless communication terminal on the reporting side is mapped from the position information is transmitted to one or more counterpart portable wireless communication terminals together with an emergency call. To do. At the same time, when a mail message corresponding to this keyword is registered in the memory 11, the mail processing unit 9a processes the mail message to create an e-mail, and 1 to a plurality of counterpart portable radio communications. Transmit to the terminal (step S207).

  When a keyword for an emergency call that substantially matches the result of voice recognition by the voiceprint / voice recognition unit 9b is not searched in the keyword / execution processing storage unit 11a of the memory 11 ("N" in step S205), FIG. Whether or not there is a keyword other than the emergency call that matches the result of the voice recognition is searched, and if there is no keyword that substantially matches this (No in step S300), the process returns to step S200 in FIG. If there is a substantially matching keyword for the contact notification (“Y” in step S300), the same processing as in the case of emergency notification is performed, and the notification side is sent from the service center 206 to the portable wireless communication terminal on the notification partner side. A map in which the current position of the portable wireless notification terminal is mapped and a contact notification are transmitted (step S301).

  FIG. 5 is a block diagram showing a second embodiment of a portable wireless communication terminal according to the present invention, in which 15 is a short-range wireless communication transmitter, 16 is a transmission antenna, 17 is a short-range wireless communication receiver, Is a receiving antenna, and parts corresponding to those in the previous drawings are given the same reference numerals and redundant description is omitted.

The signal is detected and amplified by the unit 12 and further processed by the short-range wireless communication transmission unit 15 and transmitted from the transmission antenna 16. This transmission audio signal is received by the short-range wireless communication reception unit 17 by the reception antenna 18, subjected to reception processing, and then supplied to the audio processing unit 6.

  When the call mode is set by the key operation of the key input unit 10, the audio processing unit 6 takes in the audio signal from the call microphone 7a under the control of the control unit 9, and thereby, with other portable wireless communication terminals Make calls possible. Further, when the notification mode is set by a key operation such as the end of a call of the key input unit 10, the voice processing unit 6 takes in a voice signal output from the short-range wireless communication receiving unit 17 under the control of the control unit 9. As a result, as in the previous embodiment shown in FIGS. 1 and 5, an emergency report and a report report are made to other portable wireless communication terminals.

  With this configuration, the same effect as that of the previous embodiment can be obtained in this modification as well. However, in contrast to the second embodiment shown in FIG. The terminal device main body device is used by hand, but the notification microphone 7b provided with the weak sound signal detection unit 12 and the short-range wireless communication transmission unit 15 does not have to be used by hand. It can be left in place, such as inside.

  FIG. 7 is a block diagram showing a third embodiment of the portable wireless communication terminal according to the present invention. 19 is a weak signal output unit, 20 is a weak signal input unit, and corresponds to the part corresponding to the previous drawing. Are given the same reference numerals and redundant description is omitted.

  In the figure, in the third embodiment, the microphone 7 is separated from the main unit of the portable wireless communication terminal, and is connected to the weak signal output unit 19 via the weak audio signal detection unit 12. The input audio signal is supplied to the weak signal output unit 19 via the weak audio signal detection unit 12. The weak signal output unit 19 modulates the audio signal into a frequency carrier and outputs it as a weak modulated signal with suppressed amplitude. On the other hand, in the main unit of the portable wireless communication terminal, the weak signal input unit 20 is connected to the audio processing unit 6, and the weak modulation signal output from the weak signal output unit 19 is input. The weak signal input unit 20 amplifies the input weak modulation signal to a predetermined amplitude, demodulates it to the original audio signal, and supplies it to the audio processing unit 8.

  Here, as a communication path between the weak signal output unit 19 and the weak signal input unit 20, it is mainly assumed that a human body having a property of flowing a weak current or a property of charging is used. The electrode etc. which were comprised so that attachment to a human body, clothes, etc. were used for the output terminal of the weak signal output part 19 or the input terminal of the weak signal input part 20 are used. When the human body is used as a communication path, the output terminal of the weak signal output unit 19 and the input terminal of the weak signal input unit 20 are directly attached to the human body or via a medium such as clothing, and the output terminals, Make electrostatic coupling between the input terminals. As an example of this attachment method, the microphone 7 having the weak sound signal detection unit 12 and the weak signal output unit 19 is attached to a device such as a wristwatch, and the output terminal of the weak signal output unit 19 is connected to the wristband of the wristwatch. In the portable wireless communication terminal side, the input terminal of the weak signal input unit 20 is in direct contact with the human body or arranged near the human body.

  Thus, when sound is input from the microphone 7 and a weak modulation signal is output from the weak signal output unit 19, an electric field changes on the surface of the human body, and the output terminal of the weak signal output unit 19 and the weak signal input unit The 20 input terminals are electrostatically coupled, and a current flows from the input terminal to the output terminal. As a result, the weak modulation signal is transmitted from the weak signal output unit 19 to the weak signal input unit 20.

  Thus, in order to allow the human body to be used as a communication path, in order to set the signal level so that the weak output unit 17 does not affect the human body, the weak audio signal detection unit 12 The modulation signal of the audio signal is made weak.

  As described above, also in the third embodiment, the same effect as in the second embodiment can be obtained.

The weak signal input unit 20 is connected to the audio processing unit 6.

  The weak sound signal detection unit 12 has only a function corresponding to the weak signal amplification function in the weak sound signal detection unit 12 in FIG. 7, and the weak sound signal input from the notification microphone 7b is a weak sound signal. The signal is detected and amplified by the detection unit 12, supplied to the weak signal output unit 19, and transmitted to the weak signal input unit 20 as a weak modulation signal. The weak modulation signal received by the weak signal input unit 20 is demodulated into an audio signal, amplified, and supplied to the audio processing unit 6.

  The setting of the communication mode and the notification mode accompanying the end of the communication mode are performed by key operation of the key input unit 10 as in the previous embodiment.

  As described above, this modification can also obtain the same effects as those of the third embodiment.

However, the wireless communication terminal of the present invention is not limited to this, and is a portable personal computer. Other devices may be used.

  As another modification of the second embodiment shown in FIG. 5, for example, as shown in FIG. 9, the first path 21 a in which the microphone 7 and the short-range wireless communication transmitter 15 are directly connected, and these Is provided between the microphone 7 and the weak sound signal detection unit 12 (or, although not shown, the short sound signal detection unit 12 and the short distance). A changeover switch 13a for switching between the first and second paths a and 21b may be provided between the wireless communication transmission unit 15). In this case, the control unit 9 sends a signal for switching on / off of the change-over switch 13a via the antennas 18 and 16 according to whether the call mode or the notification mode, and switches the change-over switch 13a. That is, the control unit 9 controls the changeover switch 13a so as to establish the first route 21a in the call mode, and controls the changeover switch 13a so as to establish the second route 21b in the notification mode. Also by this, the same effect as said embodiment can be acquired.

  In this case, the short-range wireless communication receiver 19 has a transmission function for transmitting a switching control signal for the changeover switch 13a, and the short-range wireless communication transmitter 15 receives a switching control signal for the changeover switch 13a. It has a receiving function.

  Similarly, also in the third embodiment shown in FIG. 7 and its modification shown in FIG. 8, the first path in which the microphone 7 and the weak signal output unit 19 are directly connected, and these are the weak audio signals. A second path connected via the detection unit 12, and between the microphone 7 and the weak sound signal detection unit 12 or between the weak sound signal detection unit 12 and the weak signal output unit 19.
