Description

  The present invention relates to a communication device connected to a wide area communication network and performing communication, and more particularly to a communication device that receives an emergency earthquake bulletin distributed by the Japan Meteorological Agency and issues an evacuation instruction.

  In recent years, with the development of communication infrastructure, various additional services related to communication have become widespread. For example, telephone devices that can connect to a wide-area communication network such as an IP telephone network or the Internet and receive various services such as a data communication service have become widespread.

  As one of the functions of such a communication device, an emergency earthquake warning receiving function delivered by the Japan Meteorological Agency in the event of an earthquake has been put into practical use. Earthquake early warning is an information distribution service that has been implemented since October 1, 2007. The user can use this service by purchasing a communication device corresponding to the earthquake early warning and making a contract with a distribution service company for the earthquake early warning.

  A communication device that has received an earthquake early warning when an earthquake occurs uses local information recorded in advance in the communication device, for example, latitude / longitude information of the location where the communication device is installed, etc. Of earthquake motion, the part most felt by the human body (usually the S wave) is calculated.

  The calculation result is notified to the user, for example, by displaying an image on a liquid crystal panel or outputting sound through a speaker. Thus, the user can take an evacuation action such as hiding under the desk or extinguishing the source of the fire before the main motion arrives from the epicenter.

  Patent Document 1 discloses an image processing apparatus that can suppress the possibility of a secondary disaster such as a fire due to an earthquake as compared with the conventional apparatus as an apparatus capable of receiving the emergency earthquake warning as described above. The image processing apparatus includes a communication control unit that performs communication with an external device, and a power source control unit that changes an energization state inside the apparatus.

  Then, when the communication control means receives the earthquake early warning from the external device, the power supply control means is controlled to change the energization state. By controlling the power supply based on external information in this way, it is possible to prevent erroneous detection of earthquakes due to vibrations other than earthquakes, such as when working nearby or accidentally colliding with equipment, without compromising convenience. Safety can be ensured.

  In relation to the above, Patent Document 2 discloses a portable early earthquake warning device capable of collecting early earthquake information and determining whether or not it is necessary to call attention before reaching the main motion of the earthquake motion. . This portable early earthquake warning device has a position information receiving means, an emergency earthquake warning receiving means, a position information received by both receiving means, and an earthquake early warning, before the arrival of the main motion of the earthquake motion. Is provided with means for determining whether or not attention is required.

According to this, since warnings can be issued before the main motion of the earthquake motion reaches the railroad vehicles and automobiles, it is possible to take measures to stop the railroad vehicles and automobiles quickly, and the occurrence of great damage. Can be prevented.

As a result, when the user receives an earthquake early warning during a call on either the main unit or the sub unit, the main unit or sub unit on the call can output a high volume evacuation instruction voice or a high volume alarm. Sound is not output. Note that a normal evacuation instruction is performed on the side that is not in a call, for example, on the side of a slave unit when a call is on the base unit side.

  In order to achieve the above object, in the communication apparatus of the present invention, the first communication unit includes a wireless communication unit connectable to a wireless communication network, and the earthquake detection transmission unit includes a wireless communication unit included in the first communication unit. The earthquake information is transmitted to the sub-communication device using a communication unit, and the second communication unit includes a wireless communication unit connectable to a wireless communication network, the earthquake information receiving unit is configured to include the second communication unit.

In addition, an upper limit of the output volume of the difficult instruction voice is set.

  According to this configuration, when the earthquake early warning is received and the communication state determining unit determines that the call is being processed, the volume adjusting unit sets the call voice to the silent state. And the upper limit of the output volume of the evacuation instruction voice is set. For example, the evacuation instruction voice is limited to the same output volume as the call voice. Thereby, only the evacuation instruction voice can be heard from the speaker.

  In order to achieve the above object, the communication device of the present invention superimposes a call voice and the evacuation instruction voice when the communication state determination means determines that the communication device is processing a call. An audio superimposing means for outputting from the audio output unit is provided.

  According to this configuration, the voice superimposing means superimposes and outputs the call voice and the evacuation instruction voice when the earthquake early warning is received and the communication state determining means determines that the call is being processed. As a result, a call voice and an evacuation instruction voice can be heard simultaneously from the speaker.

  In order to achieve the above object, the communication device of the present invention instructs the first communication unit to disconnect the call when the communication state determination unit determines that the communication device is processing a call. In addition, after completion of the disconnection, the first communication means is used to transmit to the communication device that has performed the disconnection, and information indicating that the disconnection has been performed due to the reception of the earthquake early warning A communication disconnecting means for transmitting to the communication device is provided.

  According to this configuration, the communication disconnecting unit instructs the first communication unit to forcibly disconnect the call when the earthquake early warning is received and the communication state determining unit determines that the call is being processed. . Then, after the disconnection is completed, the transmission is performed again to the communication destination that has disconnected. When communication is reestablished by re-calling, information indicating that the call has been forcibly disconnected due to the reception of the earthquake early warning is transmitted to the communication destination. For example, a standard voice message recorded in advance in the recording unit is transmitted using the first communication means.

  According to the configuration of the present invention, if it is determined that the call is being processed when the earthquake early warning is received, the upper limit of the output volume of the audio output unit is set. Thereby, even if the user receives the earthquake early warning during a call, the output of the evacuation instruction message with a large volume and the output of a high volume alarm sound are not performed. For this reason, when the user is making a call with his ears close to the speaker, a suitable evacuation instruction can be given without causing any physical or mental disabilities due to the loud sound.

  Further, according to the configuration of the present invention, the output volume is limited only when the user receives an earthquake early warning while the user is talking without using the hands-free function. Therefore, during a call using the hands-free function, an evacuation instruction with the same loud volume as before is performed, and an evacuation instruction with a predetermined volume is performed only when a normal call, that is, a call with the ear close to the speaker. For this reason, it is possible to give an evacuation instruction at an optimum volume according to the situation.

  Further, according to the configuration of the present invention, the communication device is configured to include a parent device and a child device. The master unit includes a communication state determination unit and a volume adjustment unit.

  Further, according to the configuration of the present invention, the communication device is configured to include a parent device and a child device. Both the parent device and the child device include a communication state determination unit and a volume adjustment unit. For this reason, even when the user is in a call with either the parent device or the child device, an evacuation instruction can be given at an optimum volume when receiving the earthquake early warning. In addition, since the evacuation instruction is performed as usual on the side that is not in a call, different evacuation instruction methods can be used properly on the parent device side and the child device side.

  Moreover, according to the structure of this invention, the main | base station and the subunit | mobile_unit are equipped with the wireless communication part, and evacuate instruction | indication via a wireless communication network. For this reason, there is no need to connect the master unit and the slave unit via a wired communication network. Therefore, even when the user moves the slave unit and uses it, the evacuation instruction is issued with the optimum volume according to the call state. be able to.

  Further, according to the configuration of the present invention, when the earthquake early warning is received during a call, the call voice is silenced, and only the evacuation instruction voice can be heard from the speaker. For this reason, since the user can concentrate on listening to the evacuation instruction voice without being disturbed by the call voice, the evacuation instruction content can be confirmed more reliably.

  Further, according to the configuration of the present invention, when the earthquake early warning is received during a call, the call voice and the evacuation instruction voice are superimposed and output simultaneously. For this reason, the user can listen to the evacuation instruction voice while continuing the call. For this reason, for example, the contents of the evacuation instruction voice can be transmitted to the other party while maintaining the call state, so that convenience is improved.

  Further, according to the configuration of the present invention, when an emergency earthquake warning is received during a call, the call is forcibly disconnected. Then, after the disconnection is completed, the transmission is performed again to the communication destination that has disconnected. When communication is reestablished by re-transmission, information indicating that the call is forcibly disconnected due to the reception of the earthquake early warning is transmitted to the communication destination. For this reason, the user can concentrate on the evacuation behavior and can automatically notify the other party of the occurrence of the earthquake. Therefore, for example, even when the other party is not equipped with a device for receiving an earthquake early warning, the occurrence of an earthquake can be notified, so the functionality of the communication device of the present invention is improved.

The base unit 1 is an IP telephone device capable of voice communication via a telephone network by being connected to the wired LAN 41. The base unit 1 has a relay function for relaying communication between the wired LAN 41 and the wireless communication network 42. Accordingly, the slave unit 2 described later can perform a call via the IP telephone network 61 or the PSTN network 63 by relaying the master unit 1. The base unit 1 also has a function of receiving an emergency earthquake bulletin distributed by the Japan Meteorological Agency via the Internet 62. The details of the internal structure of base unit 1 will be described later.

  The handset 2 is connected to a wireless communication network 42, which will be described later, and communicates with the base unit 1 so that the handset 2 can perform voice communication with other telephone devices via the IP telephone network 61 and the PSTN network 63. It is a communication device. The details of the internal configuration of the slave unit 2 will be described later.

  The wired LAN 41 is a local network in which the parent device 1, the IP telephone router 51, the broadband router 52, the gateway 53, and the like are connected by wire. Each of the above devices can communicate with each other by being connected to the wired LAN 41. Examples of physical means constituting the wired LAN 41 include 10BASE-T (standardized as IEEE802.3i) and 100BASE-TX (standardized as IEEE802.3u) using a twisted pair cable.

  The wireless communication network 42 is a small-scale communication network in which the parent device 1 and the plurality of child devices 2 are wirelessly connected. Specifically, for example, communication is performed using a communication system based on FHSS-WDCT (Frequency Hopping Spread Spectrum-Worldwide Digital Cordless Telephone) using radio waves in a frequency band of 2.4 GHz (gigahertz).

  The IP telephone router 51 and the broadband router 52 are network relay devices for interconnecting a plurality of IP networks. Specifically, the transfer is performed by analyzing a part of the protocol of the network layer (third layer) and the transport layer (fourth layer) in the OSI (Open Systems Interconnection) reference model. In the present embodiment, the IP telephone router 51 has a role of connecting two IP networks of the wired LAN 41 and the IP telephone network 61 to each other.

<1-2. About the internal structure of the main unit>
FIG. 2 is a block diagram showing the inside of the base unit 1 according to the first embodiment of the present invention. The base unit 1 includes at least a control unit 11, a memory 12, a display unit 13, an input unit 14, a communication control unit 15 (= first communication means), an antenna device 16 (= wireless communication unit), an audio signal processing unit 17, and a speaker. 18 (= sound output unit) and a microphone 19 are included.

  The control unit 11 is a central processing unit for performing overall control of communication control processing (voice data transmission / reception, outgoing call execution, incoming call detection, etc.) by controlling each unit of the base unit 1. Moreover, the control part 11 is an earthquake information calculation part 11a (= earthquake information calculation means) and an earthquake information transmission part 11b (= earthquake) as a function part implement | achieved by running a program on the arithmetic processing apparatus with which the control part 11 is provided. An information transmission unit), an evacuation instruction unit 11c (= evacuation instruction unit), a communication state determination unit 11d (= communication state determination unit), and a volume adjustment unit 11e (= volume adjustment unit).

  The earthquake information calculation unit 11 a receives the emergency earthquake bulletin from the Internet 62 using the communication control unit 15. For earthquake early warning, earthquake detection time, earthquake identification number, epicenter name code, epicenter latitude and longitude, epicenter depth, magnitude, maximum predicted seismic intensity, data accuracy (system and processing method used for measurement, etc.) Etc. are included. However, the predicted seismic intensity included in the earthquake early warning and the predicted time to reach the main motion are rough, and it is necessary to calculate the detailed predicted seismic intensity for each region on the receiver side.

  There are two types of calculation processing: single observation point processing and multiple observation point processing. The single observation point process is a local one-point measurement process based on the assumption that an earthquake has occurred near the observation point, such as P-wave detection and level method. The multi-observation point process is for calculating the predicted seismic intensity and the main motion arrival time of a specific place using the results of the plurality of single measurement point processes. Typical processing methods include a territory method and a grid search method.

  The earthquake information calculation unit 11 a performs multiple observation point processing based on the single observation point processing result included in the emergency earthquake bulletin and the latitude / longitude information recorded in the memory 12. Specifically, for example, first, the three elements of the earthquake (the epicenter: X, Y, the time: T, the magnitude: M) are obtained from the processing results of a plurality of single observation points. Further, the sensitive radius R is obtained from the epicenter distance (distance from the epicenter X, Y to the specific location X0, Y0) D and the magnitude M of the earthquake. In addition, the specific place here means the latitude / longitude in which the parent device 1 exists.

  The earthquake information calculation unit 11a obtains a standard strength Sr at a specific location from the epicenter distance D, the magnitude M of the earthquake, and the depth H of the epicenter. Then, the amplification factor A at a specific location according to the geological condition is obtained, and the predicted intensity, maximum speed, maximum acceleration, maximum displacement, and predicted arrival time of the main motion (S wave) are obtained using the standard intensity Sr and the amplification coefficient A. Ask. Note that the calculation method used by the earthquake information calculation unit 11a is not limited to the above-described content, and can be changed as appropriate according to the operation mode and the data content included in the earthquake early warning.

  Furthermore, the earthquake information calculation unit 11a calculates a predicted time until the main motion arrives, that is, a grace time during which the user can take evacuation action, from the predicted main motion arrival time and the current time notified from a timer (not shown). To do. The calculation result is given to the next earthquake information transmission unit 11b and the evacuation instruction unit 11c. The earthquake information calculation unit 11a performs the calculation process every time a new emergency earthquake bulletin is received.

  When the earthquake information transmission unit 11b is given the calculation result from the earthquake information calculation unit 11a, the earthquake information transmission unit 11b performs communication control on the earthquake information including the calculated main motion arrival prediction time, the predicted seismic intensity, and the predicted time until the main motion arrival. It transmits to the subunit | mobile_unit 2 using the part 15. FIG.

  The evacuation instruction unit 11c outputs an evacuation instruction corresponding to the predicted time when the predicted time from the earthquake information calculation unit 11a to the arrival of the main motion is given. For example, the evacuation instruction voice is output using the voice signal processing unit 17 and the speaker 18. In addition, the display unit 13 is used to output an evacuation instruction image. Thereby, it is possible to give an evacuation instruction according to the predicted time to the user.

  The communication state determination unit 11d determines the call state of the base unit 1 when an emergency earthquake warning is detected by the earthquake information calculation unit 11a. Specifically, it is determined whether a voice call using the communication control unit 15 and the voice signal processing unit 17 is performed by the user. When it is determined that a call is in progress, it is determined whether the hands-free function is being executed. This determination can be performed by checking the processing state of the control unit 11.

  When it is determined that the call is being processed and the hands-free function is not executed, a volume restriction instruction is given to the next volume adjustment unit 11e. At this time, the evacuation instruction unit 11c may be prohibited from outputting the evacuation instruction image using the display unit 13.

  When receiving a volume restriction instruction from the communication state determination unit 11d, the volume adjustment unit 11e reduces the gain of the amplifier included in the speaker 18 to a predetermined value and limits the upper limit value. As the upper limit value, for example, the call volume during a normal call without using the hands-free function is used as the upper limit value. As a result, even if an earthquake early warning is received during a call, it is possible to prevent the output of an evacuation instruction message or alarm sound with a large volume.

  The memory 12 is a medium for temporarily recording various data held by the parent device 1, and is configured by, for example, a writable RAM (Random Access Memory). The memory 12 serves as a buffer memory for temporarily recording processing data when various control processes are performed by the control unit 11, instruction commands received from the user, and the like.

  The display unit 13 displays various information (for example, a caller telephone number at the time of incoming call) held by the parent device 1 to the user. The display unit 13 uses, for example, a small display device that consumes less power, such as a liquid crystal panel. The input unit 14 is for a user to perform various operations (for example, input of a telephone number of a partner with whom a call is made) for performing communication using the parent device 1. The input unit 14 is generally composed of a plurality of operation buttons such as numeric buttons and redial buttons.

  The communication control unit 15 is a communication interface for connecting the parent device 1 to the wired LAN 41. The communication control unit 15 can perform incoming call processing, outgoing call processing, and the like in the IP telephone system by communicating with a call control server (not shown) connected to the wired LAN 41. In addition, the communication control unit 15 controls wireless communication via the wireless communication network 42 by the antenna device 16.

  The antenna device 16 is a wireless communication device for transmitting and receiving wireless communication radio waves to and from the handset 2. The antenna device 16 performs wireless communication in accordance with a predetermined communication standard, for example, a communication system conforming to FHSS-WDCT (Frequency Hopping Spread Spectrum-Worldwide Digital Cordless Telephone). Thereby, voice communication, data communication, etc. can be performed with the subunit | mobile_unit 2. FIG.

The audio signal processing unit 17 performs a decoding process on the audio data input by the communication control unit 15 and provides the audio signal to the speaker 18. The audio signal processing unit 17 performs predetermined encoding processing on the audio signal input from the microphone 19 to generate audio data, and supplies the audio data to the communication control unit 15. As a result, the audio data is transmitted to another telephone device connected through the wired LAN 41, the wireless communication network 42, the IP telephone network 61, or the like.

  The control unit 21 is a central processing unit for performing overall control of communication control processing (voice data transmission / reception, outgoing call execution, incoming call detection, etc.) by controlling each unit of the slave unit 2. In addition, the control unit 21 includes an earthquake information receiving unit 21a (= earthquake information receiving unit) and an evacuation instruction unit 21b (= evacuation instruction) as functional units realized by executing a program on the arithmetic processing device included in the control unit 21. Means), a communication state determination unit 21c (= communication state determination unit), and a volume adjustment unit 21d (= volume adjustment unit).

  The earthquake information receiving unit 21a determines whether earthquake information is included in various types of information received from the base unit 1. When it is determined that earthquake information is included, a message indicating earthquake detection is given to the evacuation instruction unit 21b. The evacuation instruction unit 21b to the sound volume adjustment unit 21d have the same configuration as that of the evacuation instruction unit 11c to the sound volume adjustment unit 11e of the parent device 1, and thus the description thereof is omitted here.

  The memory 22 is a medium for temporarily recording various data held by the child device 2, and is configured by, for example, a writable RAM (Random Access Memory). The memory 22 serves as a buffer memory for temporarily recording processing data when various control processes are performed by the control unit 21, instruction commands received from the user, and the like.

  The display unit 23 displays various kinds of information (for example, a caller telephone number at the time of incoming call) held by the handset 2 to the user. As the display unit 23, for example, a small and low power consumption display device such as a liquid crystal panel is used. The input unit 24 is for a user to perform various operations (for example, input of a telephone number of a partner with whom a call is made) for performing communication using the handset 2. The input unit 24 is usually composed of a plurality of operation buttons such as numeric buttons and redial buttons.

  The communication control unit 25 controls wireless communication by the antenna device 26. Thereby, the subunit | mobile_unit 2 can communicate with the main | base station 1 connected to the wireless communication network 42. FIG. Further, it is possible to perform incoming processing, outgoing processing, etc. via the PSTN network 63 by relaying the base unit 1.

Since the antenna device 26 to the microphone 29 have the same configuration as the antenna device 16 to the microphone 29 of the parent device 1, description thereof is omitted here. The battery unit 30 is supplied with electric power from an external power source (not shown) and temporarily stores the electric power. For example, a rechargeable alkaline battery or a lithium ion battery is used.
<1-4. About Evacuation Instruction Processing>
Here, with respect to the evacuation instruction process at the time of receiving the earthquake early warning using the master unit 1 and the slave unit 2 in the first embodiment of the present invention, the block diagrams of FIGS. 1 to 3 and FIGS. This will be described with reference to a flow diagram.

  FIG. 4 is a processing flow of the base unit 1 that is waiting to receive the earthquake early warning. The processing flow shown in FIG. 4 can be started at an arbitrary timing in a state where the power source of the base unit 1 is activated and communication with the Internet 62 is possible. After the start of this processing, the breaking news receiving unit 11a determines in step S110 whether or not the emergency earthquake breaking news has been received from the Internet 62 by the communication control unit 15.

  If it is determined that the emergency earthquake bulletin has not been received, the process proceeds to step S110 again, and monitoring is continued until the emergency earthquake bulletin is detected. When reception of the emergency earthquake bulletin is detected, the bulletin reception unit 11a performs processing for analyzing a message included in the emergency earthquake bulletin in step S120.

  Specifically, various parameters included in the message, for example, a predicted seismic intensity calculation parameter and a predicted time calculation parameter are acquired. Then, calculation processing using the acquired parameters and latitude / longitude information recorded in advance in the memory 12 is performed. Thereby, the predicted seismic intensity in the area where the base unit 1 is installed and the predicted main motion arrival time are calculated. Then, the current time is obtained from a timer (not shown), and the difference from the calculated main movement arrival prediction time is calculated to calculate the predicted time until arrival.

  Next, in step S130, the earthquake detection / transmission unit 11b receives the earthquake information including the predicted seismic intensity calculated by the earthquake information calculation unit 11a, the predicted arrival time of the main motion, and the predicted time until the arrival of the main motion, the communication control unit 15 and the antenna device. 16 is transmitted to one or a plurality of slave units 2.

  Next, the communication state determination unit 11d confirms the call state of the base unit 1 in step S140. In the present embodiment, since the control unit 11 performs overall call control by software processing, the communication state determination unit 11d confirms the program execution status of the control unit 11 to determine the call state / non-call. It is possible to check the status internally.

  Next, in step S150, the communication state determination unit 11d branches based on the result of confirming the call state. When it is determined that the call is not in progress, the process proceeds to step S180 described later. If it is determined that the call is in progress, branching is performed by turning on / off the hands-free function in step S160. When it is determined that the hands-free function is used, the process proceeds to step S180 described later.

  When it is determined that the handsfree function is not used, the volume adjusting unit 11e adjusts the gain of the amplifier included in the speaker 18 to a predetermined value in step S170. At the same time, an upper limit value of the gain is set, and when audio exceeding the upper limit value is output, control is performed so that the output is reduced to a predetermined value.

  Next, in step S180, the evacuation instruction unit 11c displays an evacuation instruction image using the display unit 13 and outputs an evacuation instruction sound using the audio signal processing unit 15 and the speaker 18. Then, after giving an evacuation instruction until the main movement is reached, this process is terminated.

  Next, a processing flow of the slave unit 2 will be described with reference to FIG. The processing flow shown in FIG. 5 can be started at an arbitrary timing in a state where the power of the slave unit 2 is activated and communication with the master unit 1 is possible. After the start of this process, the earthquake information receiving unit 21a determines whether or not the communication control unit 25 has received the earthquake information from the parent device 1 in step S210. The earthquake information referred to here indicates information transmitted from the parent device 1 in step S130 of FIG.

  If it is determined that the earthquake information has not been received, the process proceeds to step S210 again, and monitoring is continued until the earthquake information is detected. When the reception of the earthquake information is detected, the process proceeds to step S220, but steps S220 to S250 have the same contents as steps S140 to S170 (FIG. 4) of the base unit 1, and thus description thereof is omitted here.

  After execution of step S250, the evacuation instruction unit 21b prohibits the display unit 23 from displaying the evacuation instruction image in step S260. This is because the user cannot use the display unit 23 because the user is using the handset 2 near the ear when the handset 2 is in a call processing and the hands-free function is not used.

  Next, in step S270, the evacuation instruction unit 21b displays an evacuation instruction image using the display unit 23 and outputs an evacuation instruction sound using the audio signal processing unit 25 and the speaker 28. However, if display of the evacuation instruction image is prohibited in step S260, only the evacuation instruction sound is output. Then, after giving an evacuation instruction until the main movement is reached, this process is terminated.

  According to the above processing flow, even if an earthquake early warning is received when the user is talking with the speaker 18 or the speaker 28 close to his / her ear, an evacuation instruction is issued without using a loud evacuation instruction voice. . For this reason, there is no obstacle to the mind and body due to sudden loud sound. Moreover, in the subunit | mobile_unit 2, since it exists in the position where the display part 23 cannot be visually recognized during a telephone call, it is possible to omit useless display processing and to reduce power consumption.

Next, a second embodiment of the present invention will be described with reference to the drawings.
[Embodiment 2]
<2-1. About the configuration of the telephone system>
Since it is the same content as Embodiment 1, description is abbreviate | omitted here.
<2-2. About the internal structure of the main unit>
Although the constituent members have the same contents as those of the first embodiment, as shown in FIG. 6, a sound superimposing unit 11f (= sound superimposing means) is provided instead of the volume adjusting unit 11e. The voice superimposing unit 11f sets the gain of the amplifier of the speaker 18 to a predetermined value when the communication state determining unit 11d determines that the call is in progress, and performs voice signal processing so as to superimpose the call voice and the evacuation instruction voice. The unit 17 is instructed. Thereby, both sounds are simultaneously output from the speaker 18.
<2-3. About the internal structure of the slave unit>
An audio superimposing unit 21e is provided in place of the volume adjusting unit 21d of the first embodiment. The voice superimposing unit 21e, like the voice superimposing unit 11f of the base unit 1, superimposes and outputs the call voice and the evacuation instruction voice. Other configurations are the same as those of the first embodiment, and thus description thereof is omitted.
<2-4. About Evacuation Instruction Processing>
Here, regarding the evacuation instruction process at the time of receiving the earthquake early warning using the master unit 1 and the slave unit 2 in the second embodiment of the present invention, the block diagram of FIG. 1 and FIG. 6, the flowchart of FIG. This will be explained using. In addition, about the process of the same content as Embodiment 1, description is abbreviate | omitted by adding the same step number as FIG.

  FIG. 7 is a processing flow of the base unit 1 that is waiting to receive the earthquake early warning. The processing flow shown in FIG. 7 can be started at an arbitrary timing in a state where the power source of the base unit 1 is activated and communication with the Internet 62 is possible. Steps S110 to S150 and S180 have the same contents as those in FIG.

  If it is determined in step S160 that the handsfree function is used, the process proceeds to step S175 described later. If it is determined that the hands-free function is not used, the audio superimposing unit 11f adjusts the gain of the amplifier and limits the upper limit value in step S170.

  Next, in step S175, the voice superimposing unit 11f instructs the voice signal processing unit 17 to superimpose the evacuation instruction voice output from the evacuation instruction unit 11c and the call voice input from the outside by the communication control unit 15. . The voice superimposing unit 11f controls the communication control unit 15 so that the call is not forcibly disconnected when the evacuation instruction unit 11c starts outputting the evacuation instruction voice.

  As a result, the call voice and the evacuation instruction voice are simultaneously output from the speaker 18. Note that the volume of the evacuation instruction voice whose upper limit is restricted in step S170 is preferably the same as that of the call voice. However, it may be in a form that can be specified to superimpose either one of the volumes larger than the other by setting in advance. The superimposed output process is continued until the predicted time of arrival of the main motion, and when the output is completed, this process is terminated.

  According to the above processing flow, even if an earthquake early warning is received while the user is talking with the speaker 18 close to his / her ear, the occurrence of an earthquake is notified by the evacuation instruction voice while the call state is maintained. . For this reason, there is no obstacle to the user's mind and body due to the loud evacuation instruction voice. Further, since the evacuation instruction can be given while continuing the call, it is possible to notify the other party of the occurrence of the earthquake.

  As for the processing flow of the slave unit 2 of the present embodiment, the evacuation instruction unit 21b to the voice superimposing unit 21e (not shown) are shown in FIG. 7 when the earthquake information receiving unit 21a receives the earthquake information from the master unit 1. Processing similar to that in steps S140 to S180 is executed. For this reason, explanation is omitted for details.

Next, a third embodiment of the present invention will be described with reference to the drawings.
[Embodiment 3]
<3-1. About the configuration of the telephone system>
Since it is the same content as Embodiment 1, description is abbreviate | omitted here.
<3-2. About the internal structure of the main unit>
The components are the same as those in the first embodiment, but the control unit 11 includes a communication disconnection unit 11g (= communication disconnection unit) in addition to the earthquake information calculation unit 11a to the sound volume adjustment unit 11e. The communication disconnection unit 11g forcibly communicates when the earthquake information calculation unit 11a detects the reception of the earthquake early warning and the communication control unit 15 is performing communication processing such as voice call or FAX transmission / reception. Disconnect. Then, after the disconnection, the communication control unit 15 is used to perform re-transmission to the disconnected communication destination. When the communication is established again, notification information indicating that the communication disconnection due to the reception of the earthquake early warning is performed is transmitted to the communication destination.

As the notification information to be transmitted, for example, a standard voice message recorded in the memory 12 in advance is used. Or when the main | base station 1 has a FAX function, the form which transmits a predetermined notification image by FAX communication may be sufficient. In addition, it is desirable that the re-transmission process after the disconnection is executed as a background process of the evacuation instruction process and is not recognized by the user. Thereby, the user can concentrate on evacuation action.
<3-3. About the internal structure of the slave unit>
Since it is the same content as Embodiment 1, description is abbreviate | omitted here.
<3-4. About Evacuation Instruction Processing>
Here, the evacuation instruction process at the time of receiving the earthquake early warning using the base unit 1 according to the third embodiment of the present invention will be described with reference to the block diagrams of FIGS. 1 and 8 and the flowchart of FIG. To do. In addition, about the process of the same content as Embodiment 1, description is abbreviate | omitted by adding the same step number as FIG.

  FIG. 8 is a processing flow of the base unit 1 that is waiting to receive the earthquake early warning. The processing flow shown in FIG. 8 can be started at an arbitrary timing in a state where the power source of the base unit 1 is activated and communication with the Internet 62 is possible. Steps S110 to S180 have the same contents as those in FIG.

  After adjusting the gain of the amplifier and setting the upper limit value in step S170, the communication disconnecting unit 11g instructs the communication control unit 15 to forcibly disconnect communication in step S190. As a result, the call state transitions to the non-call state without requiring a user operation. Next, in step S200, the evacuation instruction unit 11c displays an evacuation instruction image using the display unit 13, and outputs an evacuation instruction sound using the audio signal processing unit 15 and the speaker 18.

  Next, in step S210, the communication disconnecting unit 11g performs a re-transmission to the communication destination disconnected in step S190. The destination telephone number is acquired from the communication history or the disconnection history recorded in the memory 12 or the like. When communication is established, the communication disconnecting unit 11g reads a predetermined fixed message from the memory 12 and transmits it to the communication destination in step S220.

  As the standard message, for example, a voice message such as “The call was forcibly disconnected due to the reception of the earthquake early warning. Please evacuate promptly” is used. If there is no response to the re-call and the call cannot be established, it is desirable to repeat the call until the predicted arrival time of the main movement. And this process is complete | finished by arrival of the arrival prediction time of a main motion.

According to the above processing flow, even if an emergency earthquake warning is received during a call and the call is forcibly disconnected to give priority to the evacuation instruction, the reason for disconnection can be notified to the communication destination. In addition, it is possible to notify the communication destination that an earthquake early warning has been issued. For this reason, even when the communication destination does not have an emergency earthquake warning receiver, the user of the communication destination can recognize the occurrence of the earthquake and perform evacuation activities.
