Description

  The present invention relates to a communication device that communicates by being connected to a wide area communication network, and in particular, receives an earthquake early warning distributed by the Japan Meteorological Agency, and responds to the length of predicted time until the main motion of the earthquake arrives. The present invention relates to a communication device that 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 provided in such a communication device, there is a function for receiving an emergency earthquake bulletin distributed by the Japan Meteorological Agency when an earthquake occurs. Earthquake early warning is an information distribution service that will be implemented from October 1, 2007 AD. 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.

For example, when the predicted time is 20 seconds, the user can take an evacuation action with some margin. However, if the estimated time is as short as 3 seconds, the minimum evacuation action can be taken, such as hiding under the desk.

  In the conventional communication device, since the standard message is used, the evacuation action corresponding to the situation cannot be instructed as described above.

For this reason, for example, the master unit can send an estimated time to the slave unit once, and can issue an evacuation instruction corresponding to the passage of time on the slave unit side. Therefore, in carrying out the present invention, it is possible to implement only by adding functions on the slave unit side without adding new functions on the master unit side, and versatility is enhanced.

As shown in FIG. 7A and FIG. 7B, the guidance table of this embodiment is composed of two columns, an “estimated time” column and a “guidance” column, in order from the left.

  The “predicted time” column is obtained by dividing the predicted time until reaching the main motion into a plurality of ranges by a predetermined value. For example, in the example shown in FIG. 7A, two ranges of “10 seconds or more” and “less than 10” are set with a prediction time of 10 seconds as a boundary. In the example shown in FIG. 7B, three ranges of “20 seconds or more”, “10 seconds to 19 seconds”, and “0 seconds to 9 seconds” with the prediction time of 10 seconds and the prediction time of 20 seconds as boundaries. Is set.

  The “guidance” column is a column showing guidance (= evacuation instruction content) corresponding to the range shown in the “estimated time” column. In the example shown in FIG. 7A, two types of guidance are included, and in the example shown in FIG. 7B, three types of guidance are included. For example, in FIG. 7A, when the predicted time is 15 seconds, the guidance “Check the source of the fire and hide under the desk” in the row where the “Predicted time” column is “10 seconds or longer”. Will be used.

Based on this guidance, the evacuation instruction unit 11c and the evacuation instruction unit 21b display, for example, the content of the guidance as a character image or output it as synthesized speech. Or the form which displays the pictogram which confirms the origin of a fire, or the pictogram hidden under a desk may be sufficient. Note that which guidance table in FIGS. 7A and 7B is used can be appropriately changed depending on the form of operation. Further, a form in which part or all of the values included in the “estimated time” field and the “guidance” field can be changed by the operation unit 13 or the operation unit 23 may be employed.
<1-6. 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 the flow diagram and the table diagram of FIG.

  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 process, the earthquake information calculation unit 11a determines whether or not an emergency earthquake warning has been received from the Internet 62 by the communication control unit 15 in step S110.

  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 the reception of the earthquake early warning is detected, the earthquake information calculation unit 11a performs an analysis process of a message included in the emergency earthquake early warning in step S120. Thereby, various parameters included in the electronic message, for example, a predicted seismic intensity calculation parameter and a predicted time calculation parameter are acquired.

  Next, in step S130, the earthquake information calculation unit 11a performs a calculation process using the acquired parameters and latitude / longitude information recorded in advance in the memory 12. Thereby, the predicted seismic intensity in the area where the base unit 1 is installed and the predicted main motion arrival time are calculated.

  Next, in step S140, the earthquake information calculation unit 11a calculates a predicted time until the main motion is reached. For example, the current time is acquired from a clock circuit (not shown), and the predicted time is calculated by calculating the difference from the predicted main movement arrival time calculated in step S130.

  Next, in step S150, the earthquake information transmitting unit 11b receives the earthquake information including the predicted seismic intensity calculated by the earthquake information calculating unit 11a, the predicted main motion arrival time, and the predicted time until the main motion is reached, the communication control unit 15 and the antenna device. 16 is transmitted to one or a plurality of slave units 2.

  Next, in step S160, the evacuation instruction unit 11c reads out and refers to the guidance table shown in FIG. In step S170, the guidance corresponding to the current predicted time is determined from the predicted time value and the guidance table. Then, using the display unit 13 and the speaker 18, a voice message, a character message, a pictogram, or the like corresponding to the guidance is output.

  For example, when the predicted time is 15 seconds and the content of the guidance table is the configuration shown in FIG. 7A, the voice message corresponding to the guidance “Check the source of the fire and hide under the desk.” , And text messages are output. If the display unit 13 has a function of displaying a pictogram, a pictogram indicating that the source of the fire is extinguished or hidden under the desk is displayed.

  Next, in step S180, the evacuation instruction unit 11c updates the predicted time when a predetermined time has elapsed. For example, every time 1 second elapses, updating is performed to reduce the estimated time by 1 second. When the current time exceeds the predicted arrival time, the predicted time value is negative. In step S190, it is determined whether the current prediction time is 0 or more. When it is 0 or more, it transfers to step S160 again and outputs the evacuation instruction according to prediction time.

  At this time, if it is necessary to change the content of the evacuation instruction, for example, in the example shown in FIG. 7A, when the predicted time changes from 10 seconds or more to less than 10 seconds, Interrupt and output new evacuation instructions. Therefore, even in the middle of an evacuation instruction according to the guidance “Check the source of the fire and hide under the desk.” The guidance “For under the desk.” Switch to evacuation instructions.

  In step S190, when the current predicted time is less than 0, that is, minus, this process is terminated. At this time, the evacuation instruction being output may be stopped, or the main power supply of the communication device may be stopped.

  Next, the processing flow in the subunit | mobile_unit 2 is demonstrated, using the flowchart of FIG. The processing flow shown in FIG. 5 can be started at an arbitrary timing when the handset 2 is in a standby state and wireless communication with the base unit 1 is possible. After the start of this process, the earthquake information acquisition unit 21a determines in step S210 whether or not the antenna device 26 has received the earthquake information related to the occurrence of the earthquake from the parent device 1.

  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 earthquake information acquisition unit 21a extracts the predicted time to reach the main motion from the earthquake information received from the base unit 1 in step S220. The extracted predicted seismic intensity and predicted time are given to the evacuation instruction unit 21b.

  Next, in step S230, the evacuation instruction unit 21b reads and references the guidance table shown in FIG. In step S240, the guidance corresponding to the current predicted time is determined from the predicted time value and the guidance table. Then, using the display unit 23 and the speaker 28, a voice message, a text message, a pictogram, or the like corresponding to the guidance is output.

  Next, in step S250, the evacuation instruction unit 21b updates the predicted time when a predetermined time has elapsed. In step S260, it is determined whether the current prediction time is 0 or more. When it is 0 or more, it transfers to step S240 again and outputs the evacuation instruction according to prediction time.

  In step S260, when the current prediction time is less than 0, that is, minus, this process is terminated. At this time, the evacuation instruction being output may be stopped, or the main power supply of the communication device may be stopped.

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>
The components are the same as those in the first embodiment, but the functions of the earthquake information transmitting unit 11b and the evacuation instruction unit 11c are partially different from those in the first embodiment. The earthquake information transmission unit 11b of the present embodiment updates the predicted time until the arrival of the main motion given from the earthquake information calculation unit 11a using a timer (not shown) every predetermined time, for example, every second.

  And whenever prediction time is updated, the newest prediction time is transmitted to the subunit | mobile_unit 2 using the communication control part 15. FIG. However, when a new prediction time is calculated by the earthquake information calculation unit 11a, the prediction time is updated based on the new prediction time. At this time, the data regarding the old predicted time is discarded. Moreover, the form which notifies a user that the prediction time was changed by transmitting the signal which shows that the new prediction time was calculated to the subunit | mobile_unit 2 may be sufficient.

Moreover, the evacuation instruction | indication part 11c of this embodiment discriminate | determines the guidance used for an evacuation instruction | indication using a predicted seismic intensity in addition to the prediction time to the main motion arrival given from the earthquake information calculation part 11a. A specific example of the guidance table will be described later.
<2-3. About the internal structure of the slave unit>
The components are the same as those in the first embodiment, but the function of the evacuation instruction unit 21b is partially different from that in the first embodiment. Unlike the first embodiment, the evacuation instruction unit 21b of the present embodiment does not update the predicted time every predetermined time. Therefore, whenever the estimated time is given from the earthquake information acquisition unit 21a, the evacuation instruction unit 21b determines the type of guidance to be used and outputs an evacuation instruction.

Moreover, the evacuation instruction | indication part 21b of this embodiment is the content of the guidance output by prediction earthquake intensity in addition to the prediction time to the main movement arrival given from the earthquake information acquisition part 21a similarly to the evacuation instruction | indication part 11c of the main | base station 1. Is determined.
<2-4. External structure of slave unit>
Since it is the same content as Embodiment 1, description is abbreviate | omitted here.
<2-5. Guidance table structure>
FIG. 8 is a guidance table in which the predicted time until the arrival of the main motion, the predicted seismic intensity, and the guidance corresponding to the predicted time and the predicted seismic intensity are associated. As shown in FIG. 8, the guidance table of the present embodiment is composed of three columns of a “predicted time” column, a “predicted seismic intensity” column, and a “guidance” column in order from the left.

  The “predicted time” column and the “guidance” column have the same contents as those in the first embodiment, and thus description thereof is omitted. The difference between the guidance table of FIG. 8 and Embodiment 1 is the “predicted seismic intensity” column. The “predicted seismic intensity” column is obtained by dividing the predicted seismic intensity of the main motion into a plurality of ranges by a predetermined value. For example, in the example shown in FIG. 8, two ranges of “less than seismic intensity 5” and “greater than seismic intensity 5” are set with the predicted seismic intensity 5 as a boundary.

Therefore, the “guidance” column does not have a one-to-one correspondence with the “predicted time” column, and is uniquely identified by determining two values of “predicted time” and “predicted seismic intensity”. For example, when the predicted time is 15 seconds and the predicted seismic intensity is 4, the guidance “Check the source of fire and hide under the desk.” On the third line from the top is used. As in the first embodiment, some or all of the values included in the “predicted time” column, “predicted seismic intensity” column, and “guidance” column can be changed by the operation unit 13 or the operation unit 23. May be.
<2-6. About Evacuation Instruction Processing>
Here, regarding the evacuation instruction processing 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 FIGS. 1 to 3 and the table of FIG. This will be described with reference to the flowcharts of FIGS. 9 and 10. In addition, about the process of the same content as Embodiment 1, description is abbreviate | omitted by adding the same step number.

  FIG. 9 is a processing flow of the base unit 1 prepared for the earthquake early warning. The processing flow shown in FIG. 9 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 S160 have the same contents as those in the first embodiment, and thus description thereof is omitted.

  In step S160, after reading and referring to the guidance table recorded in the memory 12, in step S175, the evacuation instruction unit 11c calculates the current predicted time and the predicted time from the predicted time, the predicted seismic intensity value, and the guidance table. Determine guidance corresponding to seismic intensity. Then, using the display unit 13 and the speaker 18, a voice message, a text message, a pictogram, or the like corresponding to the guidance is output.

  For example, when the predicted time is 5 seconds, the predicted seismic intensity is 6, and the content of the guidance table is the configuration shown in FIG. 8, it corresponds to the guidance “Hide under the desk” in the bottom row. Voice messages and text images are output. If the display unit 13 has a function of displaying a pictogram, a pictogram indicating that it is hidden under the desk is displayed.

  Next, in step S180, the evacuation instruction unit 11c updates the predicted time when a predetermined time has elapsed. In step S195, it is determined whether the current prediction time is 0 or more. When it is 0 or more, it transfers to step S150 again, and outputs the notification of the estimated time to a subunit | mobile_unit, and the evacuation instruction | indication continuously.

  Next, the processing flow in the subunit | mobile_unit 2 is demonstrated, using the flowchart of FIG. Step S210 has the same contents as those in the first embodiment, and thus description thereof is omitted. When the reception of the earthquake information is detected in step S210, the earthquake information acquisition unit 21a extracts the predicted seismic intensity and the predicted time to reach the main motion from the earthquake information received from the base unit 1 in step S225. The extracted predicted seismic intensity and predicted time are given to the evacuation instruction unit 21b.

  Next, in step S230, the evacuation instruction unit 21b reads and references the guidance table shown in FIG. In step S245, the guidance corresponding to the current predicted time and the predicted seismic intensity is determined from the predicted time and the predicted seismic intensity value and the guidance table. And after outputting images, such as a voice message according to guidance, a character message, or a pictogram, using the display part 23 and the speaker 28, this process is complete | finished.

At this time, if an evacuation instruction corresponding to any of the guidances has already been performed and the guidance determined in step S245 is the same as the current guidance, the current evacuation instruction process is continued and a new No evacuation instruction processing is performed. As a result, it is possible to prevent unnecessary processing such as re-outputting a voice message or the like from the beginning although there is no change in the guidance.
