Description

  The present invention relates to a disaster information receiving apparatus that receives and reports information on disasters, for example, earthquake early warnings distributed by the Japan Meteorological Agency and the like.

  In recent years, the Japan Meteorological Agency has started providing a service called Earthquake Early Warning. To explain this earthquake early warning in detail, the Japan Meteorological Agency places seismometers at multiple points, collects data from this seismometer when an earthquake occurs, and based on the collected data, the longitude, latitude, The depth of the epicenter and the magnitude (magnitude) of the earthquake are calculated, and the calculated data is notified to a specific terminal or business operator.

More specifically, a case will be described in which data is transmitted from the Japan Meteorological Agency to the terminal via the operator. In this case, the Meteorological Agency, a business operator, and a terminal are connected, and when an earthquake occurs, data relating to the earthquake is transmitted in order from the Meteorological Agency to the business operator and the terminal.
Specifically, when the meteorological agency sends data on the longitude, latitude, depth of the epicenter, and magnitude of the earthquake (magnitude) of the epicenter to the business operator, On the basis of the location information of the terminal that has joined the terminal, the time until the seismic intensity and shaking at the location where the terminal exists is immediately calculated, and these data are transmitted to the terminal.

In addition, there is a system in which information on the epicenter transmitted from the Meteorological Agency to the terminal from the business side is transmitted as it is, and the predicted seismic intensity is calculated on the terminal side. In this case, the terminal uses the regional information recorded in advance on the terminal, for example, the latitude / longitude information of the place where the terminal is installed, etc. The estimated time at which the portion (usually S wave) will reach is calculated.
The calculation result is notified to the user by, for example, 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.

In addition, in connection with such a terminal, the applicant of the present invention can establish a communication device that can carry out an emergency earthquake warning on a trial basis so that it can be simulated to experience what happens when an earthquake early warning comes. Proposed in Patent Document 1.
Japanese Patent Application No. 2007-334627

  However, in the technique described in Patent Document 1, when the real earthquake early warning is received while the earthquake early warning test is being performed, the notification form is the same. As a result, there is a problem that even if a real earthquake early warning is received, preparations for the earthquake cannot be made immediately.

The disaster information receiving apparatus according to claim 1 includes a disaster information receiving unit that receives disaster information, and a notification unit that notifies disaster information in response to the reception of disaster information by the disaster information receiving unit. The disaster information can be notified on a trial basis by the notification section, the notification form of the pilot disaster information notification by the notification section, and the notification of the disaster information according to the disaster information reception by the disaster information reception section It is characterized by making the form different.
The disaster information receiving apparatus according to claim 2 is the disaster information receiving apparatus according to claim 1, and the notification unit is a display unit that displays disaster information, and is used for notification of experimental disaster information. The display mode of the display unit is different from the display mode of the display unit when the disaster notification is performed on the display unit in response to the disaster information reception of the disaster information receiving unit.
The disaster information receiving device according to claim 3 is the disaster information receiving device according to claim 1 or 2, wherein the notification unit is a display unit that displays disaster information, and provides notification of experimental disaster information. The display color of the background of the display unit when performing and the display color of the background of the display unit when performing disaster notification in the display unit according to the reception of the disaster information of the disaster information receiving unit are different .
The disaster information receiving device according to claim 4 is the disaster information receiving device according to claim 1, wherein the notification unit notifies the disaster information with a voice message and performs experimental disaster information notification. The voice message is different from the voice message when performing disaster notification according to the disaster information reception of the disaster information receiving unit.
The disaster information receiving device according to claim 5 is a disaster information receiving unit that receives the disaster information, a notification unit that notifies the disaster information in response to the reception of the disaster information of the disaster information receiving unit, and the disaster information on a trial basis. When the disaster information receiving unit receives the disaster information while the disaster information is being reported on a trial basis, the information about the received disaster information is stopped when the disaster information is received. The notification form of the notification of the experimental disaster information by the notification unit is different from the notification form of the notification of disaster information according to the reception of the disaster information by the disaster information receiving unit. .

  According to the present invention, since the notification mode when the disaster information is notified on a trial basis is different from the notification mode when the disaster information is actually received and the disaster information is notified, the user can test the disaster information on a trial basis. Even if real disaster information arrives, the preparation for an earthquake can be made immediately without being confused with the test notification.

  According to the invention described in claim 2, since the display form when the disaster information is notified on a trial basis is different from the display form when the disaster information is actually received and the disaster information is notified, the user When conducting disaster information notification on a trial basis, even if true disaster information arrives, it is not confused with test notification, and can immediately prepare for an earthquake.

Moreover, the control part 21 is provided with the earthquake detection receiving part 21a and the earthquake early warning notification part 21b as a function part implement | achieved by running a program on the arithmetic processing apparatus with which the control part 21 is provided.

  The earthquake detection receiving unit 21a determines whether or not an emergency earthquake bulletin is included in various information received from the base unit 1. When it is determined that the earthquake early warning is included, a telegram indicating earthquake detection is given to the earthquake early warning notification unit 21b.

  The earthquake early warning notification unit 21b reads the earthquake early warning data recorded in the flash memory 30 when an electronic message indicating earthquake detection is given from the earthquake detection receiving unit 21a. Then, by outputting the read data using the display unit 23 and the speaker 28, earthquake early warning is performed.

  The flash memory 20 also stores a voice message output from the speaker 18 and message data to be displayed on the display unit 13 when an earthquake notification is made on a trial basis.

  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.

<1-4. Explanation of the operation of the apparatus of this embodiment>
Next, the operation of the embodiment apparatus to which the present invention is applied will be described with reference to the flowchart of FIG.

  FIG. 5 is a flowchart showing the operation of base unit 1. In step S01, if the control unit 11 determines that there has been an operation for instructing to perform earthquake notification from the input unit 14 on a trial basis (test mode), the process proceeds to step S02; otherwise, the process proceeds to step S03. To proceed.

  In step S02, the control unit 11 executes a test mode. Specifically, the test mode display data (FIG. 6A) stored in the flash memory 20 is read and displayed on the display unit 13. In the display data of FIG. 6A, the character color indicating seismic intensity is black and the background color is green. The display data is not limited to the letter indicating the seismic intensity, but may be a countdown display until the shaking comes (for example, 5 seconds until the shaking comes).

  Further, when executing the test mode, the control unit 11 sends a test mode voice message from the flash memory 20 (for example, “I will perform an emergency earthquake warning test. An earthquake with a seismic intensity of 5 will occur” or “Emergency We will test the earthquake early warning. An earthquake with a seismic intensity of 5 will be left for another 5 seconds. ”) Is read and output from the speaker 18.

  In step S03, when the control unit 11 determines that the communication control unit 15 has received the earthquake early warning, the process proceeds to step S04.

  In step S04, the control unit 11 determines from the received information such as the longitude and latitude of the epicenter, the depth of the epicenter, and the intensity of the earthquake, and the longitude and latitude information of the own device stored in advance in the memory. Calculate the magnitude of the earthquake and the time to shake. Next, the calculated magnitude of earthquake and time until shaking will be reported. Specifically, as shown in FIG. 6B, the control unit 11 displays characters indicating the magnitude of the earthquake in white and the background in red on the display unit 13. Also, an earthquake notification voice message (for example, “An earthquake early warning was received. An earthquake with a seismic intensity of 5 has arrived.” Or “Emergency earthquake early warning has been received. An earthquake with a seismic intensity of 5 is 5 seconds away.” Etc.) is output from the speaker 18.

  In this way, in the present embodiment device, the notification mode in the emergency earthquake warning test mode is different from the notification mode when the emergency earthquake warning is actually received, so the user can use the emergency earthquake warning test mode. Even if a real earthquake early warning is received during execution, it can be recognized as a real earthquake early warning. For this reason, it is possible to prepare for an earthquake immediately while the test mode is being executed.

  Subsequently, in step S05, if the control unit 11 determines that there is an instruction operation for canceling the test mode from the input unit 14, the process proceeds to step S06, and otherwise returns to step S03.

  In step S06, the control unit 11 interrupts the test mode and returns the display unit 13 to a normal standby screen (for example, a screen displaying time).

  In this embodiment, the operation is performed in the case of the parent device 1, but the same can be applied to the child device 2. In this embodiment, the cordless telephone that can receive the earthquake early warning is used. However, the facsimile apparatus, the cellular phone device that can receive the emergency earthquake early warning, the disaster information receiving apparatus that can receive only the emergency earthquake early warning, and the like. It can be implemented similarly.

  6 (A) and 6 (B), the background is green and the characters are black, and the background is red and the characters are white. However, the display is not limited to this, and each display is different. It would be good if
