In addition, the mobile phone 6 has a GPS function for acquiring current position information of its own device and a communication function for sending and receiving mails to and from the earthquake early warning receiving device 5 via the Internet network 4.

  When an earthquake occurs at any location, the seismometer 1 closest to the epicenter first senses the seismic wave and transmits the observation data to the Japan Meteorological Agency 2. The Japan Meteorological Agency 2 analyzes the data with a computer and calculates an estimated value of the earthquake occurrence time, location, and scale (magnitude).

  The estimated time, location, and magnitude (magnitude) of the earthquake thus calculated are transmitted to broadcast stations and other organizations as emergency earthquake alerts. The earthquake early warning distribution server 3 of the information distributor registered as one of them is also sent to the earthquake early warning distribution server 3, and the earthquake early warning distribution server 3 receives the emergency earthquake early warning received from the Japan Meteorological Agency, It transmits to the earthquake early warning receiving device 5 via the Internet network 4.

  FIG. 2 is a block diagram showing a schematic configuration of the earthquake early warning receiving device 5 according to one embodiment of the present invention. The earthquake early warning receiving apparatus includes a control unit 10, a display unit 11, an operation unit 12, a memory 13, a communication unit 14, a voice processing unit 15, a speaker 16, and the like. The earthquake early warning receiving device 5 calculates a predicted seismic intensity and a postponement arrival time based on the emergency earthquake early warning distributed from the earthquake early warning distribution server 3 and the current location information registered in advance, and notifies the user by voice or display. Inform. The control unit 10 corresponds to the calculation unit of the present invention, the memory 13 corresponds to the current position information holding unit of the present invention, and the communication unit 14 corresponds to the current position information acquisition unit of the present invention.

  The control unit 10 is mainly composed of a microprocessor, and includes a memory such as a ROM and a RAM as in a general computer device, reads various control programs stored in the ROM, and stores a program storage area in the RAM. In response to the control program, various control processes of the earthquake early warning receiver are performed.

  The display unit 11 is a display unit composed of a liquid crystal panel or the like. Under the control of the control unit 10, various text data and image data such as emergency earthquake warning, earthquake information such as predicted seismic intensity and postponement arrival time are displayed on a liquid crystal screen. Display.

  The operation unit 12 includes various operation keys, and inputs various data by operating the operation keys. The input data is sent to the control unit 10. The memory 13 stores keywords (for example, “current position automatic registration”) that are added to the current position information and the current position information registration mail such as the latitude, longitude, and ground amplification factor of the point where the earthquake early warning receiver is installed. Etc.) are stored. The communication unit 14 is connected to the Internet network 4 and receives emergency earthquake bulletins distributed from the earthquake bulletin distribution server 3 in addition to transmission / reception of call data such as mail.

  The control unit 10 receives the mail analysis function for determining whether the subject or the body of the mail received from the mobile phone 6 includes a keyword indicating that the current position information registration mail is stored in the memory 13 in advance. And a location information registration function for registering location information accompanying the received email in the memory 13 based on the analysis result of the received email.

  Further, the control unit 10 calculates the predicted seismic intensity and the postponement time based on the emergency earthquake bulletin received from the earthquake bulletin distribution server 3 and the position information held in the memory 13. The calculated predicted seismic intensity and postponement arrival time are given to the display unit 11, the voice processing unit 15, and the like.

  The voice processing unit 15 converts the predicted seismic intensity and the arrival delay time calculated by the control unit 10 into a voice signal and outputs the voice signal from the speaker 17. In addition, the predicted seismic intensity and the arrival delay time calculated by the control unit 10 are also given to the display unit 11, and the display unit 11 displays them on the display screen.

  If the user manually inputs the current position information stored in the memory 13 of the earthquake early warning receiving device 5, it takes time and is likely to cause erroneous input. In addition, if the earthquake early warning receiving device 5 includes a self-position detecting means having a GPS function, or if a GPS device separate from the emergency earthquake early warning receiving device 5 is used, the cost increases.

  Therefore, in the present invention, the current position information is registered using the mobile phone 6 having a GPS function. Mobile phones are now widely used by people, and many mobile phones have built-in GPS functions, including mail functions and infrared communication functions. The latitude and longitude are measured at a proximity position of the breaking news receiving device 5 and transmitted to the emergency earthquake breaking news receiving device 5 by mail or infrared communication.

  Here, an operation when registering the current position using the mail function of the mobile phone will be described.

  FIG. 3 is a sequence diagram for explaining the operation of current position registration according to an embodiment of the present invention.

  First, in the earthquake early warning receiving device 5, in step S501, a keyword indicating that it is a current position information registration mail, for example, “current position automatic registration” using the operation unit 12 or the like, is set in the memory 3 in advance and waits. It becomes a state.

  In step S601, the mobile phone 6 that is initially in a standby state activates the GPS function based on the user's operation, and the current location information (latitude and longitude) of the mobile phone 6 in the proximity of the emergency earthquake warning receiver 5 is obtained. To get.

  Next, in step S602, the mail function is activated based on the user's operation, and the keyword “current position automatic registration” indicates that the mail is the current position information registration mail for the e-mail address of the earthquake early warning receiving device 5. Is included in the subject or text and the acquired current position information is attached, and the e-mail is transmitted via the Internet 4 in the next step S603.

  When the control unit 10 controls the communication unit 14 and the communication unit 14 receives an e-mail, the earthquake early warning receiving device 5 analyzes the received mail in step S502. That is, it is determined whether or not the keyword “current position automatic registration” preset in the memory 3 is included in the email received by the control unit 10. Since this e-mail includes the keyword “current position automatic registration” in the subject or text, the control unit 10 detects the keyword “current position automatic registration” from the subject or text of the e-mail.

  When the earthquake early warning receiving device 5 detects the keyword “current position automatic registration” from the received mail, in step S503, the control unit 10 extracts position information attached to the received mail and stores the emergency information in the memory 3. The current position information of the earthquake early warning receiver 5 is registered. On the other hand, if no keyword is detected from the received mail, the normal mail receiving process is performed and the process ends.

  In the above embodiment, when transmitting location information accompanying an e-mail, an emergency earthquake is generated by adding a keyword indicating that the e-mail is for current location information registration in the subject of the e-mail or in the e-mail text. Although the present location information registration process can be automated on the breaking news receiving device 5 side, the present invention is not limited to this, and the emergency earthquake breaking news receiving device 5 is configured by making the transmission mail itself a format unique to the current location information registration mail. The current position information registration process may be automated on the side.

  In this case, a unique identification code indicating that the current position information is registered is written in the header of the e-mail, and the control unit 10 of the earthquake early warning receiving device 5 analyzes the header of the received mail. If the identification code indicating that it is a mail for current position information registration is included in the header part, the position information attached to this received mail is extracted, and the earthquake early warning is received in the memory 3 The current position information of the device 5 is registered.

  Further, in the above embodiment, the position information is transmitted along with the e-mail using the mail function. However, the present invention is not limited to this, and the position information is transmitted to the earthquake early warning receiver 5 using the infrared communication function. It is good also as composition to do.

In addition, to calculate the predicted seismic intensity and grace time based on the earthquake early warning, not only the current position information but also the ground amplification factor is required, but the ground amplification factor is a value that is uniquely determined from longitude and latitude. Therefore, if the data of the ground amplification factor is stored in the memory 13 of the earthquake early warning receiving device 5 in correspondence with the longitude and latitude, the ground amplification factor at that point is obtained using the longitude and latitude at the current position as keys. can do.
However, if the data of the ground amplification factor is held in each earthquake early warning receiving device 5, the burden on the memory 13 of each earthquake early warning receiving device 5 becomes large. Therefore, the earthquake early warning distribution server 3 stores the data of the ground amplification factor corresponding to the longitude and latitude, and the ground amplification factor at that point is used as the key for the longitude and latitude at each current position. It is also possible to adopt a system configuration such as that obtained from 3. By doing so, the load on the memory 13 of each earthquake early warning receiver 5 is reduced.

  As described above, according to the emergency earthquake bulletin distribution system according to the present invention, when an earthquake early warning receiver is installed at home or the like, a general user can easily perform registration of current position information according to the installation location. In addition, the risk of erroneous input can be reduced by automating the position registration work as much as possible.

  In addition, when the current position information acquisition function using GPS or the like is incorporated in the earthquake early warning receiving device itself, the cost of the device is increased, and there is a possibility that positioning cannot be performed depending on the radio wave condition depending on the installation location in the house.

  However, in the present invention, the current location information is acquired by using the GPS function of the cellular phone that is being installed as standard, and transferred to the earthquake early warning receiver, so that the main body of the earthquake early warning receiver can be connected to a power source or a LAN. While the installation location is limited by the connection, it is possible to move to a location with good reception sensitivity such as a window or a veranda if it is a mobile phone, so this problem can also be avoided. Therefore, user convenience can be improved.

  In the above embodiment, the distribution of the emergency earthquake bulletin from the earthquake bulletin distribution server 3 to the emergency earthquake bulletin receiving device 5 is performed via the Internet network 4. However, the present invention is not limited to this. Other communication means such as a beacon that transmits traffic information to a passing vehicle may be used.

  The emergency earthquake bulletin receiving device 5 does not necessarily have to use a dedicated terminal, and is used by adding the function of the emergency earthquake bulletin receiving device to a device having other functions, for example, a cordless telephone or an answering machine. May be.
