Thereby, as described above, the audio signal is transmitted to the external communication device of the communication partner via the telephone line 7 by the signal control unit 3s.

  In addition, the second command control unit 5b detects whether or not the wireless communication state of the second wireless communication unit 5a (that is, the wireless communication state between the child device 5 and the parent device 3) is a communication disconnection.

  More specifically, the second command control unit 5b transmits a predetermined signal (that is, a detection signal for detecting whether or not communication is interrupted) from the second wireless communication unit 5a to the first wireless communication unit 3n. . When the second wireless communication unit 5a receives the response signal to this transmission from the first wireless communication unit 3n, the second command control unit 5b detects that the communication is not disconnected (that is, communication is connected). .

That is, the first command control unit 3p of the base unit 3 detects from the first wireless communication unit 3n to the second wireless communication unit 5a a predetermined signal (that is, whether or not communication is interrupted) at a first predetermined time interval. Detection signal). When the second wireless communication unit 5a receives the predetermined signal from the first wireless communication unit 3n at the first predetermined time interval, the second command control unit 5b On the other hand, if the second wireless communication unit 5a does not receive the predetermined signal from the first wireless communication unit 3n for a second predetermined time longer than the first predetermined time, the second command control unit 5b detects that the communication is interrupted.

  The charging unit 5c is a non-contact charging unit (for example, a non-contact type such as an electromagnetic dielectric method, an electric field coupling method, a radio wave method, or an electric field resonance method). The charging unit 5c includes a power receiving unit (not shown) that receives power supplied from the charging base 9 in a non-contact manner using electromagnetic interaction (for example, electromagnetic dielectric, electric field coupling, radio wave, or electric field resonance), and the power receiving unit A storage battery (not shown) that is charged with the power received by the unit. When the charging unit 5c is arranged on the charging stand 9, it is charged by being fed from the charging stand 9 in a non-contact manner.

  The charging stand 9 is a non-contact charger that is the same as the charging unit 5 c and operates with electric power from an external power source (commercial power source here) 13. When the handset 5 is placed on the charging stand 9, the electric power is supplied to the charging unit 5c of the handset 5 in a non-contact manner using electromagnetic interaction to charge the charging unit 5c.

  In addition, since the charging stand 9 operates with the external power supply (commercial power supply) 13, at the time of a power failure, the external power supply 13 is turned off and the charging stand 9 stops. Therefore, at the time of a power failure, the charging unit 5c of the child device 5 stops the power supply from the charging stand 9 and stops charging (that is, charging is interrupted).

  Here, the charging unit 5c and the charging base 9 are non-contact type, but may be a connection type in which the charging unit 5c and the charging unit 9 are terminal-connected.

  The charging state detection unit 5e determines whether the charging unit 5c is being charged by the charging base 9 based on, for example, the charging / discharging current and charging / discharging voltage of the storage battery of the charging unit 5c (that is, whether the charging is disconnected). ) Is detected.

  The acceleration sensor 5f is disposed in the housing of the child device 5 in which the respective constituent elements 5a to 5k, 5m, 5n, and 5p to 5r are accommodated and detects the acceleration of the housing. 5 acceleration is detected. Here, instead of the acceleration sensor 5f or together with the acceleration sensor 5f, an angular velocity sensor that detects the rotation speed of the slave unit 5 may be used.

  The light emitting unit 5g is composed of a light emitting element such as an LED (light emitting diode), for example, and functions as an emergency light during a power failure.

  The second display unit 5h is a non-light emitting display unit (here, a liquid crystal display unit). The 2nd illumination part 5i is a backlight part which irradiates illumination light from the back of the 2nd display part 5h, for example, and illuminates the 2nd display part 5h. A transflective plate is disposed between the second display unit (ie, the liquid crystal display unit) 5h and the second illumination unit (ie, the backlight unit) 5i, and when the second illumination unit is turned off, The second display section 5h is illuminated with the reflected light from the transflective plate of external light incident on the front surface of the second display section 5h.

  When a call request operation is input to the second operation unit 5p, the second display control unit 5j displays information on the destination (for example, a telephone number) on the second display unit 5h. In addition, when the second command control unit 5b receives the incoming notification signal from the base unit 3 via the second wireless communication unit 5a, the second display control unit 5j displays the information (for example, telephone number) of the incoming call source. 2 Display on the display 5h.

  The second speaker 5m outputs a sound signal according to the control of the second main control device 5q, in addition to outputting a sound signal according to the control of the second sound control unit 5n.

  The second audio control unit 5n decodes the audio signal received by the second wireless communication unit 5a and outputs the audio signal from the second speaker 5m under the control of the second command control unit 5b. In addition, the second voice control unit 5n encodes the voice signal acquired from the second microphone 5k under the control of the second command control unit 5b, and transmits the encoded voice signal from the second wireless communication unit 5a to the parent device 3.

  The second main controller 5q controls each of the components 5a to 5k, 5m, 5n, 5p, and 5r so as to operate as described above.

  Further, the second main controller 5q detects whether or not a change has occurred in the detection value of the acceleration sensor 5f (that is, the acceleration of the slave unit 5). When the detection result is affirmative (that is, there is a change), each detection value of the acceleration sensor 5f for a predetermined time from the time when the change occurrence is detected is stored in the second data storage unit 5r in time series.

  In addition, the second main control device 5q detects (e1) the second command control unit 5b that the wireless communication state of the second wireless communication unit 5a is disconnected, and (e2) the charge state detection unit 5e. When it is detected that the charging unit 5c is disconnected, the detection values of the acceleration sensor 5f during the predetermined time stored in the second data storage unit 5r in time series immediately before the detection are detected. Based on the above, the type of power outage (earthquake power outage and normal power outage) is distinguished and the occurrence of power outage is detected.

  When at least one of (e1) and (e2) is not detected, the second main controller 5q does not detect the occurrence of a power failure (that is, detects that a power failure has not occurred).

  More specifically, the second main controller 5q detects a detected value of a certain level or more based on each detected value of the acceleration sensor 5f during the predetermined time stored in the second data storage unit 5r in time series. It is determined whether or not (acceleration) exists (more specifically, whether or not a detected value of a certain level or more is continuously present for a certain time or more). If the determination result is affirmative, the second main controller 5q determines that an earthquake power failure has occurred (that is, detects the occurrence of an earthquake power failure), and on the other hand, if the determination result is negative, The second main controller 5q determines that a normal power failure has occurred (that is, detects the occurrence of a normal power failure).

  Based on the detection result of the occurrence of the power outage, the second main controller 5q is a target of the operation of the slave unit 5 (that is, the light emission operation of the light emitting unit 5g, the ringing operation of the second speaker 5m, and the power saving operation). Control the operation mode of the component operation.

  Note that the components that are targets of the power saving operation include at least the second display unit 5h, the second display unit (backlight unit) 5i, the second wireless communication unit 5a, and the charging unit 5c.

  Moreover, as an operation mode of the subunit | mobile_unit 5, the normal mode, the normal power failure mode, and the earthquake power failure mode are set, for example.

  The normal mode is an operation mode when the occurrence of a power failure is not detected. In the normal mode, the component that is the target of the power saving operation is operated in the first power saving operation mode. Specifically, in the first power saving operation mode, as shown in FIG. 3, for example, the second display unit 5h is turned off, the second illumination unit 5i is turned off, and the second wireless communication unit 5a is operated. The charging unit 5c is turned on, and the other target components are turned on.

  In the normal mode, the light emitting unit 5g and the second speaker 5m are operated in the first power failure operation mode. Specifically, in the first power failure operation mode, as shown in FIG. 3, the light emitting unit 5g is turned off and the second speaker 5m is stopped (that is, the notification sound is turned off).

  The normal power failure mode is an operation mode when the occurrence of a normal power failure is detected, and is an operation mode for returning the handset 5 as a telephone as soon as possible. In the normal mode, the component that is the target of the power saving operation is operated in the second power saving operation mode. Specifically, in the second power saving operation mode, as shown in FIG. 4, for example, the second display unit 5h is turned on, the second illumination unit 5i is turned off, and the second wireless communication unit 5a is operated. The charging unit 5c is turned on and the other target components are turned off.

  In the normal power failure mode, the light emitting unit 5g and the second speaker 5m are operated in the second power failure operation mode. Specifically, in the normal power failure mode, as shown in FIG. 4, the light emitting unit 5g is turned on and the second speaker 5m is stopped (that is, the notification sound is turned off).

  Here, in the normal power failure mode, the light emitting unit 5g is turned on, but may be blinked.

  The earthquake power failure mode is a power saving mode when the occurrence of an earthquake power failure is detected, and is an operation mode for keeping the light emission time of the light emitting unit 5g as long as possible. In the earthquake power failure mode, the component that is the target of the power saving operation is operated in the third power saving operation mode. Specifically, in the third power saving operation mode, as shown in FIG. 5, for example, the second display unit 5h is turned off, the second illumination unit 5i is turned off, and the second wireless communication unit 5a is operated. The charging unit 5c is turned on, and the other target components are turned off.

  In the earthquake power failure mode, the light emitting unit 5g and the second speaker 5m are operated in the third power failure operation mode. Specifically, in the third power failure operation mode, as shown in FIG. 5, the light emitting unit 5g blinks (for example, SOS blinks), and a notification sound is emitted from the second speaker 5m (that is, the notification sound is turned on). ).

  Here, in the earthquake power failure mode, the light emitting unit 5g blinks, but may be lit. In addition, it is desirable for the light emission pattern of the light emission part 5g to differ by earthquake power failure mode and normal power failure mode. For example, when lighting in normal power failure mode, it is preferable to blink in earthquake power failure mode, or when blinking in normal power failure mode, it is desirable to blink in earthquake power failure mode or blinking pattern different from that in normal power failure mode. .

  More specifically, as shown in FIG. 3, the second main controller 5q controls the operation of the slave unit 5 to the normal mode when the occurrence of a power failure is not detected (that is, in the normal time).

  In the normal state, as shown in FIG. 3, the power supply of the main unit 3 is turned on (that is, the power supply state from the external power supply 11), and the power supply of the charging base 9 is turned on (ie, the power supply state from the external power supply 13). ) Therefore, the charging state of the charging unit 5c of the child device 5 is being charged, and the wireless communication state of the second wireless communication unit 5a of the child device 5 is a communication connection state. Further, the detected value of the acceleration sensor 5f of the slave unit 5 is not changed (that is, the acceleration is not changed).

  In addition, as shown in FIG. 4, the second main controller 5 q controls the operation of the slave unit 5 to the normal power failure mode when the occurrence of a normal power failure is detected (that is, in the case of a normal power failure).

  In the case of a normal power failure, as shown in FIG. 4, the power source of the master unit 3 is turned off (that is, the power is cut off), and the power source of the charging stand 9 is turned off (that is, the power is turned off). Therefore, the charging state of the charging unit 5c of the child device 5 is disconnected, and the wireless communication state of the second wireless communication unit 5a of the child device 5 is disconnected. Further, the detected value of the acceleration sensor 5f of the slave unit 5 is not changed (that is, the acceleration is not changed).

  In the normal power failure mode state, the second command control unit 5b detects that the wireless communication state of the second wireless communication unit 5a is a communication connection state, or the charging state detection unit 5e is charging the charging unit 5c. Is detected, the second main controller 5q determines that the normal power failure has been restored, and returns the operation of the slave unit 5 to the normal mode.

  In addition, as shown in FIG. 5, the second main controller 5 q controls the operation of the slave unit 5 in the earthquake power failure mode when the occurrence of the earthquake power failure is detected (that is, at the time of the earthquake power failure).

  In the case of an earthquake power failure, as shown in FIG. 5, the power source of the main unit 3 is turned off (that is, the power is cut off), and the power source of the charging stand 9 is turned off (that is, the power is turned off). Therefore, the charging state of the charging unit 5c of the child device 5 is disconnected, and the wireless communication state of the second wireless communication unit 5a of the child device 5 is disconnected. Further, the detection value of the acceleration sensor 5f of the slave unit 5 is changed (that is, the acceleration is changed).

  When the charging state detection unit 5e detects that the charging unit 5c is being charged in the earthquake power failure mode state, the second main controller 5q determines that the earthquake power failure has been restored, and the slave unit 5 is returned to the normal mode.

<Description of operation>
Based on FIG. 6, the main operation of the handset 5 will be described. FIG. 6 is a flowchart for explaining the main operation of the handset 5.

  In step S1, the handset 5 is placed on the charging stand 9 and is in a standby state at the normal time without a power failure. In this standby state, the communication connection state of the second wireless communication unit 5a of the handset 5 is the communication connection state, and this communication connection state is detected by the second command control unit 5b. The charging state of the charging unit 5c of the slave unit 5 is being charged, and this charging state is detected by the charging state detection unit 5e. Based on these detection results, the second main controller 5q detects that a power failure has not occurred (that is, the normal time), and the operation mode of the slave unit 5 is controlled to the normal mode. .

  In this normal time, the power source of the main unit 3 and the power source of the charging stand 9 are each in an on state (that is, during power feeding from the external power sources 11 and 13). Then, the process proceeds to step S2.

  In step S2, whether or not a change has occurred in the detection value of the acceleration sensor 5f is detected by the second main controller 5q. As a result of this detection, when a change occurs in the detection value of the acceleration sensor 5f (YES), the process proceeds to step S3. On the other hand, when no change occurs in the detection value of the acceleration sensor 5f (NO), The process proceeds to step S4.

  In step S3, each detected value of the acceleration sensor 5f for a predetermined time from the time when the second main controller 5q detects that the detected value of the acceleration sensor 5f has changed is second data in time series. It is stored in the storage unit 5r. Then, the process proceeds to step S4.

  In step S4, whether or not the charging unit 5e is disconnected is detected by the charging state detection unit 5e. As a result of the detection, when the charging unit 5e is not disconnected (NO), the process returns to step S1, while when the charging unit 5e is disconnected (YES), the process proceeds to step S5.

  In step S5, the second command control unit 5b detects whether or not the wireless communication state of the second wireless communication unit 5a (that is, the wireless communication state between the child device 5 and the parent device 3) is a communication disconnection. . As a result of this detection, when the wireless communication state of the second wireless communication unit 5a is not disconnected (NO), the process returns to step S1, while the wireless communication state of the second wireless communication unit 5a is disconnected. In (YES), the process proceeds to step S6.

  In step S6, the second main controller 5q detects a certain level or more based on each detected value of the acceleration sensor 5f during the predetermined time stored in the second data storage unit 5r in time series in step S3. It is determined whether or not there is a value (acceleration) (more specifically, whether or not a detected value of a certain level or more is continuously present for a certain period of time). When the determination result is affirmative (YES), it is determined by the second main controller 5q that an earthquake power failure has occurred, and the process proceeds to step S7. On the other hand, when the determination result is negative (NO), it is determined by the second main controller 5q that a normal power failure has occurred, and the process proceeds to step S9.

  In step S7, the operation mode of the handset 5 is shifted to the earthquake power failure mode by the second main controller 5q. Then, the process proceeds to step S8.

  In step S8, whether or not the charging unit 5c is being charged is detected by the charging state detection unit 5e. As a result of the detection, when the charging unit 5c is not charging (NO), the second main controller 5q determines that the earthquake power failure has not been recovered, and the process returns to step S7. On the other hand, if the charging unit 5c is being charged as a result of the detection (YES), the second main controller 5q determines that the earthquake power failure has been restored, and the process returns to step S1 to perform the second main control. The operation of the slave unit 5 is returned to the normal mode by the device 5q.

  In step S9, the operation mode of the handset 5 is shifted to the normal power failure mode by the second main controller 5q. Then, the process proceeds to step S10.

  In step S10, whether or not the charging unit 5c is being charged is detected by the charging state detection unit 5e. If the charging unit 5c is being charged as a result of this detection (YES), the second main controller 5q determines that the normal power failure has been restored, the process returns to step S1, and the second main controller 5q Thus, the operation of the slave unit 5 is returned to the normal mode. On the other hand, if the charging unit 5c is not charging as a result of the detection (NO), the second main controller 5q determines that the normal power failure has not been restored, and the process proceeds to step S11.

  In step S11, the second command control unit 5b detects whether or not the communication connection state of the second wireless communication unit 5a is a communication connection state. As a result of the detection, when the communication connection state of the second wireless communication unit 5a is not the communication connection state (NO), the second main control device 5q determines that the normal power failure has not been recovered, and the process proceeds to step S9. Return to. On the other hand, as a result of the detection, when the wireless communication state of the second wireless communication unit 5a is the communication connection state (YES), the second main controller 5q determines that the normal power failure has been restored, and the process is stepped. Returning to S1, the operation of the handset 5 is returned to the normal mode by the second main controller 5q.

  Next, based on FIG. 7, the content (earthquake blackout mode) of step S7 of FIG. 6 is demonstrated. FIG. 7 is a flowchart for explaining the contents of step S7 in FIG.

  In step S7-1, the second main controller 5q determines whether or not the constituent element that is the target of the power saving operation has been shifted to the third power saving operation mode. If the determination result is affirmative (YES), the process proceeds to step S7-6, and if the determination result is negative (NO), the process proceeds to step S7-2.

  In step S7-2, the second main controller 5q turns off the second illumination unit 5i via the second display control unit 5j. In step S7-3, the second main control unit 5q turns off the operation of the second display unit 5h via the second display control unit 5j. In step S7-4, the second main communication device 5q turns off the operation of the second wireless communication unit 5a via the second command control unit 5b. In step S7-5, the second main controller 5q turns off the other components that are the targets of the power saving operation. Then, the process proceeds to step S7-6.

  In step S7-6, the second main controller 5q determines whether or not the light emitting unit 5g and the second speaker 5m have already been shifted to the third power failure operation mode. If the determination result is affirmative (YES), the operation is completed. On the other hand, if the determination result is negative (NO), the process proceeds to step S7-7.

  In step S7-7, the light emitting unit 5g is blinked (for example, SOS blinks) by the second main controller 5q. In step S7-8, the second main controller 5q outputs (generates) a notification sound from the second speaker 5m. This completes the operation.

  Next, based on FIG. 7, the content of step S9 in FIG. 6 (normal power failure mode) will be described. FIG. 7 is a flowchart for explaining the contents of step S9 in FIG.

  In step S9-1, the second main controller 5q determines whether or not the constituent element that is the target of the power saving operation has been shifted to the second power saving operation mode. If the determination result is affirmative (YES), the process proceeds to step S9-4. If the determination result is negative (NO), the process proceeds to step S9-2.

  In step S9-2, the second main controller 5q turns off the second illumination unit 5i via the second display control unit 5j. In step S9-3, the second main control device 5q turns off the operation of other components that are the targets of the power saving operation. Then, the process proceeds to step S7-6.

  In step S9-4, the second main controller 5q determines whether or not the light emitting unit 5g and the second speaker 5m have already shifted to the second power failure operation mode. If the determination result is affirmative (YES), the operation is completed. On the other hand, if the determination result is negative (NO), the process proceeds to step S9-5.

  In Step S9-5, the light emitting unit 5g is turned on by the second main controller 5q. This completes the operation.

<Main effects>
According to the fixed telephone system 1 configured as described above, (a) the charge state detection unit 5e detects that the charge is disconnected, and (b) the second command control unit 5b (communication state detection unit). In the first state in which it is detected that communication is interrupted and (c) the acceleration sensor 5f has detected an acceleration of a certain level or higher, it is determined that a power failure due to an earthquake has occurred. The occurrence of a power failure due to an earthquake can be detected without a function (such as a LAN-compatible function) for receiving an emergency earthquake warning.

  In particular, the occurrence of a power failure is detected by (a) and (b), and the occurrence of an earthquake is detected by the condition of (c). From the above, it is possible to detect the occurrence of a power outage due to an earthquake without using the emergency earthquake bulletin.

  In more detail, in the case of the first state, when it is determined by the acceleration sensor 5f that acceleration of a certain level or more has continued for a certain period of time, it is determined that a power failure due to an earthquake has occurred. Even if the acceleration is above a certain level, one-off ones are eliminated, so that it is possible to prevent erroneous detection of the occurrence of an earthquake.

  When it is determined that a power failure due to an earthquake has occurred, the light emitting unit 5g is lit or blinked, so that the light emitting unit 5g can be automatically lit or blinked. Moreover, since the charging part 5c (namely, power supply) is provided, the light emission part 5g can be utilized as an emergency light at the time of a power failure.

  When it is determined that a power failure due to an earthquake has occurred, a notification sound is output from the second speaker 5m (speaker), so that a power failure due to an earthquake can be notified to the surroundings with a notification sound. In the event of a power outage, the rescue team can be notified that there are people here.

  In the case of the first state, the second wireless communication unit 5a (wireless communication unit) is further turned off, so that the power consumption of the charging unit 5c (that is, the power source) can be reduced and the light emitting unit 5g. It is possible to ensure a long lighting or blinking time. That is, since it takes time to recover from a power failure due to an earthquake, the charging unit 5c can be preferentially used for lighting or blinking the light emitting unit 5g.

  In the case of the first state, the second display unit 5h (display unit) is further turned off and the second illumination unit 5i (illumination unit) is turned off. ) Can be reduced, and the lighting or blinking time of the light emitting part 5g can be secured for a long time. That is, since it takes time to recover from a power failure due to an earthquake, the charging unit 5c can be preferentially used for lighting or blinking the light emitting unit 5g.

  Also, a second state in which it is detected that the charge is cut off by the charge state detection unit 5e, and that the communication is cut off by the second command control unit 5b, and an acceleration of a certain level or more is not detected by the acceleration sensor 5f. In the case of, it is determined that a power outage not caused by an earthquake has occurred. For example, even if there is no function (for example, a LAN-compatible function) that receives emergency earthquake warnings distributed by the Japan Meteorological Agency, a power outage not caused by an earthquake occurs. Can be detected.

  In more detail, in the case of the second state, if it is not detected by the acceleration sensor 5f that acceleration of a certain level or more has continued for a certain period of time, it is determined that a power failure not caused by an earthquake has occurred. Even if the acceleration is above a certain level, the one-shot ones are excluded, so that it is possible to prevent erroneous detection of the occurrence of an earthquake.

  Further, when it is determined that a power outage not caused by an earthquake has occurred, the light emitting unit 5g is lit or blinked, so that the light emitting unit 5g can be automatically lit or blinked. Moreover, since the charging part 5c (namely, power supply) is provided, the light emission part 5g can be utilized as an emergency light at the time of a power failure.

  In the case of the second state, since the second wireless communication unit 5a is turned on, the communication function of the second wireless communication unit 5a can be promptly restored at the time of recovery from a power failure not caused by an earthquake. That is, since a power failure not caused by an earthquake such as a planned power failure is restored immediately, the second wireless communication unit 5a is turned on so that the communication function can be quickly restored at the time of restoration.

  Further, in the case of the second state, since the second illumination unit 5i is turned off, the power consumption of the charging unit 5c (that is, the power source) can be reduced correspondingly, and the lighting or blinking time of the light emitting unit 5g is lengthened. It can be secured.

  In addition, the communication terminal device according to the present invention is a base unit 3 that is connected to the telephone line 7 and operates by power feeding from the external power source 11, and a base unit 3 that is wirelessly connected via the second radio communication unit 5a. The handset 3 can be used as the communication terminal device.

  Moreover, the subunit | mobile_unit 3 of the fixed telephone system 1 provided with the main | base station 3, the subunit | mobile_unit 5, and the charger 9 can be used as the said communication terminal device.
