Description

  The present invention calculates the predicted seismic intensity, the postponement time of arrival, etc. at a plurality of notification target points including the current position based on emergency disaster bulletins such as emergency earthquake bulletins delivered by the Japan Meteorological Agency, and notifies the user by voice or display. The present invention relates to an emergency disaster bulletin receiving device.

  2. Description of the Related Art Recently, an earthquake early warning receiving device having a function of receiving an earthquake early warning for advanced users provided by the Japan Meteorological Agency and notifying a user of a predicted seismic intensity and a postponement arrival time has been developed. In this emergency earthquake early warning receiver for advanced users, the earthquake information (latitude, longitude, depth, magnitude) included in the telegram data of emergency earthquake early warnings for advanced users provided by the Japan Meteorological Agency and pre-registered in its own device From the target point information (latitude, longitude, ground amplification), the predicted seismic intensity and the arrival delay time at the target point are immediately calculated, and the user is notified before reaching the main motion.

  Further, this emergency earthquake warning system for advanced users can technically calculate not only the current position where the receiving device is installed, but also the predicted seismic intensity and grace time at any point. For example, Patent Document 1 (Japanese Patent Laid-Open No. 2007-133642) below proposes a disaster information distribution method that can quickly obtain disaster information at a point where a user is or a desired point.

  In this disaster information distribution method, if the location information of a specific point is registered in advance in the information terminal, the disaster information of the specific point is calculated in the information terminal based on the basic information about the disaster transmitted from the disaster information transmission center, The calculated disaster information of the specific point is displayed on the information terminal.

  In this way, the user can quickly obtain disaster information at his or her desired location regardless of day or night, regardless of where he / she is, so that he can immediately respond to disasters and prevent secondary disasters. It becomes possible.

JP 2007-133642 A (paragraph [0023], FIG. 4)

  However, in the conventional disaster information transmission system, the display method when a plurality of target points are simultaneously notified is not specifically considered, and thus is not necessarily highly convenient for the user. It was.

  For example, emergency earthquake warnings for advanced users place the utmost importance on promptness, and are announced several times (for example, about 5 to 10 times) within a few seconds to 1 minute after the earthquake detection, and gradually from the first report. A number of pieces of information are announced while improving accuracy, and when the accuracy is almost stabilized, a final report as final information is announced, and the provision of a series of emergency earthquake warnings for the earthquake ends.

  Here, since the grace time to be obtained by the earthquake early warning is a short time of several seconds to several tens of seconds, the prediction calculation for the current position of the user directly linked to the safety of the user is performed as quickly as possible, The result needs to be immediately notified to the user using voice or screen display.

  However, as described above, emergency earthquake warnings for advanced users release multiple pieces of information for a single earthquake in a short time. There is a concern that the load will increase and the prediction calculation processing and notification processing targeting the current position of the user, which is the original application, will be hindered. In particular, in an embedded device having inferior processing capability compared to a personal computer or the like, the influence cannot be ignored.

  The inventor of the present application has conducted various studies to solve the above-described problems. As a result, the prediction calculation result for the current position where the device is installed is intended to cope with the seismic motion approached by the user of the device. However, the prediction calculation results for areas other than the current location are used to confirm the impact of the earthquake on family members who live far away. Focusing on the fact that the current position is not high, the prediction calculation for the current position is performed for all information (from the first report to the final report) included in the emergency earthquake warning for advanced users. The present invention has been completed by conceiving that the above-mentioned problems can be solved if the target prediction calculation is executed only once using only the final report, which is definite information.

  That is, the present invention has an object to solve the above-mentioned problems, and a plurality of points including the current position can be obtained without hindering the prediction calculation process and the notification process for the current position as the original application. The purpose is to make the target prediction calculation feasible.

  In order to solve the above-mentioned problem, the invention according to claim 1 of the present application is an emergency disaster bulletin receiving device that receives distribution of emergency disaster bulletins announced in a plurality of stages via a network. Registration means (for example, corresponding to the operation unit 16 in the following embodiment) for registering position information of a plurality of notification target points including the current position of the device, and holding means for holding position information registered by the registration means ( For example, in the following embodiment, it corresponds to the storage unit 15), receiving means for receiving the emergency disaster bulletin via the network (for example, in the following embodiment, corresponding to the communication control unit 14), and held in the holding means On the basis of the positional information being made and the emergency disaster bulletin received by the receiving means, calculating means for calculating disaster information at each notification target point (for example, in the following embodiment, Control unit 11), notification means for notifying the user of the disaster information calculated by the calculation means by voice or display (for example, in the following embodiment, corresponds to the display unit 17 and the voice output unit 18), When calculating the disaster information by the calculation means, it is determined whether or not the emergency disaster bulletin received by the reception means is an emergency disaster bulletin at a predetermined stage, and the notification target held in the holding means according to the determination result Control means (for example, it corresponds to control part 11 in the following example) which controls to calculate disaster information for a predetermined point among points is provided.

  The invention according to claim 2 of the present application is the emergency disaster bulletin receiving device according to claim 1, wherein the control means determines that the received emergency disaster bulletin is other than the final report in the information determination stage. Is controlled to calculate disaster information only for the position of the own device among the notification target points held in the holding means.

  Further, in the invention according to claim 3 of the present application, in the emergency disaster bulletin receiving device according to claim 1 or 2, the control means determines that the received emergency disaster bulletin is a final report at an information confirmation stage. In this case, control is performed so that disaster information is calculated for all notification target points held in the holding unit.

  The emergency disaster bulletin receiving device of the present invention has the following effects. That is, in the invention according to claim 1, when a plurality of target points including the current position of the user's own device desired by the user can be pre-registered and an emergency disaster bulletin announced in multiple stages is received, It is determined whether or not the received emergency disaster bulletin is an emergency disaster bulletin at a predetermined stage, and a prediction calculation process for a predetermined registration point is performed according to the determination result to perform an appropriate notification process.

  According to such a configuration, according to the stage of the emergency disaster bulletin, the prediction calculation of the disaster information only for a predetermined registration point is performed, or the prediction calculation of the disaster information for all the registration points is performed. By doing so, it is possible to perform an appropriate notification process that minimizes the load of the prediction calculation process.

  Further, in the invention according to claim 2, in the emergency disaster bulletin receiving device according to claim 1, when it is determined that the received emergency disaster bulletin is other than the final bulletin at the information confirmation stage, the registered notification target The disaster information is calculated only for the position of the own device among the points.

  According to such a configuration, a plurality of points including the current position are targeted without impeding the prediction calculation process and the notification process for the position (current position) of the own apparatus that the user needs most. Prediction calculation can be realized.

  Further, in the invention according to claim 3, in the emergency disaster bulletin receiving device according to claim 1 or claim 2, if it is determined that the received emergency disaster bulletin is the final report in the information finalizing stage, it is registered. Disaster information is calculated for all notification target points.

  According to such a configuration, with respect to the registration point other than the current position, by performing the calculation only once using only the final report that is the confirmation information, the load of the prediction calculation process is minimized, Prediction calculation for a plurality of points including the current position can be realized without hindering the prediction calculation process and the notification process for the position of the user's own device (current position) that is most needed by the user. A highly convenient emergency disaster bulletin receiving device can be provided.

  Hereinafter, specific examples of the present invention will be described in detail with reference to examples and drawings. However, the embodiment described below exemplifies an emergency disaster bulletin receiving device for embodying the technical idea of the present invention, and is intended to specify the present invention as this emergency disaster bulletin receiving device. Instead, the present invention can be equally applied to the emergency disaster bulletin receiving apparatus of other embodiments included in the scope of claims.

  FIG. 1 is a diagram showing a schematic configuration of an emergency earthquake bulletin distribution system according to an embodiment of the present invention. The earthquake early warning distribution system includes a fixed telephone 1 and cordless telephone devices 2 and 3, and the fixed telephone 1 and the base unit 2 of the cordless telephone apparatus are connected via an Internet network 4. . Here, the fixed telephone 1 and the base 2 of the cordless telephone apparatus are IP telephones having a function of receiving emergency disaster warnings such as emergency earthquake warnings via the Internet network 4. The earthquake early warning is distributed from the earthquake early warning distribution server 7 of a specific distributor. Here, an emergency earthquake bulletin distribution system will be described.

  When an earthquake occurs at any location, the seismometer 5 closest to the epicenter among the many seismometers installed in each location senses the seismic wave first and transmits the observation data to the Japan Meteorological Agency 6. The Japan Meteorological Agency 6 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 7 of the information distributor registered as one of them is also sent to the earthquake early warning distribution server 7, and the earthquake early warning distribution server 7 contracts the emergency earthquake early warning received from the Japan Meteorological Agency 6. Distribution is made via the Internet 4 to telephones (in FIG. 1, the fixed telephone 1 and the cordless telephone apparatuses 2 and 3).

  When the fixed telephone 1 and the cordless telephone devices 2 and 3 receive the earthquake early warning from the earthquake early warning distribution server 7, based on the received emergency earthquake early warning, at a plurality of target points including the current position registered in advance. The predicted seismic intensity and the postponement arrival time are calculated and notified to the user by voice or display.

  Next, the configuration of the fixed telephone according to the embodiment of the present invention will be described.

  FIG. 2 is a block diagram showing a schematic configuration of the fixed telephone 1 according to the embodiment of the present invention. The fixed telephone 1 includes a control unit 11, an audio input / output unit 12, an audio signal processing unit 13, a communication control unit 14, a storage unit 15, an operation unit 16, a display unit 17, an audio output unit 18, and the like. .

  The control unit 11 corresponds to the control unit and the calculation unit of the present invention, the communication control unit 14 corresponds to the reception unit of the present invention, the storage unit 15 corresponds to the holding unit of the present invention, and the operation unit 16 corresponds to the main unit. The display unit 17 and the audio output unit 18 correspond to the notification unit of the present invention.

  Further, the present embodiment shows a fixed telephone as an emergency disaster bulletin receiving apparatus, but is not limited to this, and a terminal having an IP telephone function such as the cordless telephone apparatuses 2 and 3 and answering machine shown in FIG. It may be a device.

  The control unit 11 is mainly composed of a microprocessor, and includes a ROM and a RAM (not shown) as in a general computer device. The control unit 11 reads various control programs stored in the ROM, develops them in a program storage area in the RAM, and performs various control processes of the fixed telephone 1 according to the control programs.

  The voice input / output unit 12 inputs a transmitted voice via a microphone during a call or outputs a received voice via a speaker. The voice signal processing unit 13 processes the received voice signal from the communication control unit 14 and outputs it via the voice input / output unit 12, or processes the transmitted voice input via the voice input / output unit 12. Then, it is converted into an audio signal and sent to the communication control unit 14.

  The communication control unit 14 is connected to the Internet network 4, and controls incoming calls from the IP telephone line and outgoing calls to the telephone line to transmit / receive telephone call data, as well as an emergency distributed from the earthquake early warning distribution server 7. Receives earthquake early warnings and sends / receives emails to / from fixed telephones (for example, cordless telephone devices 2 and 3).

  The storage unit 15 can store setting conditions for various functions of the fixed telephone 1 and can also store registration information such as a telephone book and a speed dial that the user inputs from the operation unit 16. In this telephone directory, position information can be stored together with personal information such as name, telephone number, mail address, and address. Furthermore, in this invention, the memory | storage part 15 is present position information, such as the latitude of the point in which the fixed telephone 1 is installed as an object point which alert | reports earthquake information, such as a predicted seismic intensity and a grace time, and a ground amplification factor, Location information of other points desired by the user, for example, telephone numbers such as family residences and friend residences registered in advance from the operation unit 16 and regional information (location information) corresponding to those area codes and their regions Is stored in a notification target table for storing the ground amplification factor together with the priority order of notification targets.

  FIG. 3 shows an example of the notification target table stored in the storage unit 15. As shown in FIG. 3, the registration point position information and the ground amplification factor are stored in association with each other in descending order of the priority of the notification target.

  Specifically, for example, in the first priority order, the current position information of the home where the fixed telephone 1 used by the user is installed is “35 ° 11′N, 134 ° 14” which is latitude / longitude information. “E” and “1.aa” which is the ground amplification factor at the position are stored, and the second priority is “0790−” which is the telephone number of the child's residence as the family residence (location information). 42-*** ”,“ Kasai City ”which is the municipality corresponding to the area code, and“ 1.bb ”which is the ground amplification factor of the area are stored.

  The current position information stored in the storage unit 15 may be input by the user from the operation unit 16, or the fixed telephone 1 is provided with a self-position detecting unit having a GPS function and automatically registered. Also good. In addition, the area information (position information) and the ground amplification factor of other points may be searched and set by connecting to various information providing servers via the Internet network 4.

  The operation unit 16 includes a numeric keypad for inputting numbers and characters, a call key for operating a call and starting a call, a call end key for operating a call end, and a phone book for registering / searching a phone book. It consists of keys, mode setting keys that perform operations to set various modes, etc. Operate numeric keys and operation keys to select various functions such as input of various data such as phone number and mail input and call operation Also used when setting. The input data is sent to the control unit 11. Furthermore, the operation unit 16 is used for registering position information of a point desired by the user as a target point for notifying earthquake information and for specifying a priority order.

  The display unit 17 is a display unit composed of a liquid crystal panel or the like. Under the control of the control unit 11, the other party's phone number and name, call duration, call charge, received mail, etc. read from the phone book are displayed. In addition, in the present invention, as will be described later, the communication control unit 14 performs control based on the earthquake early warning received from the earthquake early warning distribution server 7 and the location information stored in the emergency earthquake early warning and the storage unit 15. The earthquake information calculated by the unit 11 (predicted seismic intensity, arrival time delay, etc.) can also be displayed.

  The voice output unit 18 converts the earthquake information calculated by the control unit 11 into a voice signal based on the emergency earthquake bulletin received from the earthquake bulletin distribution server 7 and the position information held in the storage unit 15 and converts it into a voice signal (see FIG. (Not shown).

  Here, emergency earthquake warnings for advanced users are confirmed information when the accuracy is almost stabilized after multiple information is announced with gradually increasing accuracy from the first report within a few seconds to 1 minute after earthquake detection. In the fixed telephone 1 of the present invention, the first received by the control unit 11 from the earthquake early warning distribution server 7 is announced. The predicted seismic intensity and the postponement arrival time are calculated based on all the earthquake early warnings from the first report to the final report and the current position information in the first priority stored in the storage unit 15. The calculated predicted seismic intensity and arrival delay time are given to the display unit 17 or the voice output unit 18.

  Further, when receiving the final emergency earthquake warning, the control unit 11 of the present invention uses the location information for each area code after the second priority stored in the storage unit 15. The predicted seismic intensity and the postponement time for the area corresponding to the area code of other points registered as notification targets are also calculated and given to the display unit 17 or the voice output unit 18.

  Here, the earthquake early warning distribution server 7 is a mode in which the fixed telephone 1 can discriminate between the final emergency earthquake early warning and the other emergency early warnings from the first to the last final report, for example, at least the final emergency earthquake. An identifier to that effect is added to the bulletin so that the fixed telephone 1 can detect it, and each emergency earthquake bulletin is distributed to the fixed telephone 1.

  The display unit 17 calculates earthquake information such as predicted seismic intensity and grace time at each point calculated by the control unit 11 based on the earthquake early warning received from the earthquake early warning delivery server 7 and the position information held in the storage unit 15. Is displayed on the display screen with a message with different contents depending on the distance from the epicenter. Here, when displaying the earthquake information of the final report, it is preferable to display the earthquake information in consideration of the priority order of the notification target.

  FIG. 4 is a diagram showing an example of a display screen at the time of earthquake information notification according to the embodiment of the present invention. That is, as shown in FIG. 4 (a), the first priority is given to the earthquake early warning from the first report to immediately before the final report (FIG. 4 (b) shows the first earthquake early warning). Earthquake information at the point (home) where the fixed telephone 1 is installed is displayed. Specifically, assuming that an earthquake has occurred off Tottori Prefecture, the point where the fixed telephone 1 registered in the storage unit 15 is installed is close to this epicenter, and is calculated by the control unit 11. Based on the predicted seismic intensity and the postponement time, the message “A large earthquake off Tottori Prefecture has occurred. After 20 seconds, a seismic intensity of less than 4 will sway.” Is displayed. At this time, it is preferable that the voice output unit 18 converts earthquake information such as predicted seismic intensity and arrival delay time calculated by the control unit 11 into a voice signal and outputs the voice signal from a speaker (not shown).

  In this way, the calculation of the earthquake information at the point where the fixed telephone 1 registered with the highest priority is installed is prevented from being hindered by the calculation of the earthquake information at other points, and more quickly. Prediction calculation processing and notification processing for the current position can be performed.

  Also, in FIG. 4B, the final earthquake early warnings at each point are listed in descending order of priority. Specifically, since the epicenter, the magnitude of the earthquake, etc. could be observed accurately, the calculated predicted seismic intensity and grace time at the point where the fixed telephone 1 registered with the highest priority is installed. Based on the above, the message “An earthquake occurred in the eastern coast of Tottori Prefecture. After 10 seconds, the earthquake will have a seismic intensity of over 5” will be displayed, and the child's residence registered as the next highest priority will be calculated. Based on the predicted seismic intensity and the postponement time, a message “Shakes with seismic intensity of less than 4 after 10 seconds” is displayed.

  In addition, as shown in FIG. 4 (b), the earthquake at the point where the fixed telephone 1 registered with the highest priority is installed so that the earthquake information at the highest priority point is easily visible. Preferably, the information is displayed in a large space in about two-thirds of the display screen area, and earthquake information for other priority points is displayed in about one-third of the remaining display screen area.

  In this way, it is possible to prevent the display of earthquake information at the highest priority point (here, the home where the fixed telephone 1 is installed) from being disturbed by the display of earthquake information at other points. Since the space for displaying earthquake information of other priorities is small, when many points of other priorities are registered and cannot be displayed on one screen, they are divided and displayed on a plurality of display screens.

  Moreover, the audio | voice output part 18 converts earthquake information, such as the predicted seismic intensity and arrival delay time which the control part 11 calculated, into an audio | voice signal, and makes it output from a speaker (not shown). At this time, preferably, the control unit 11 gives only the earthquake information at the point where the fixed telephone 1 registered with the highest priority is installed to the voice output unit 18 and displays the earthquake information at other points. If it is made to give to the part 17, grasping | ascertainment of alerting | reporting content will become easy for a user.

  Next, a method for notifying the earthquake early warning of the fixed telephone according to the present embodiment will be described.

  FIG. 7 is a flowchart showing the operation of the fixed telephone according to the embodiment of the present invention. Note that the processing shown in FIG. 7 is realized by executing a control program stored in a ROM provided in the control unit 11.

  First, in step S51, when the control unit 11 waiting for receiving the earthquake early warning receives the earthquake early warning from the earthquake early warning distribution server 7 by the communication control unit 14, in step S52, the control unit 11 includes the emergency earthquake early warning. If the received earthquake early warning is the final report, the process proceeds to step S53 if it is not the final report. On the other hand, if the received earthquake early warning is the final report Then, the process proceeds to step S55.

  In the process of step S53, the control unit 11 determines the current location based on the location information at the point where the fixed telephone 1 registered as the first priority in the storage unit 15 is installed and the received earthquake early warning. Calculate the predicted seismic intensity and grace time at the location.

  In step S54, the earthquake information such as the predicted seismic intensity calculated by the control unit 11 and the postponed arrival time is displayed on the display unit 17, and the sound information is output via the audio output unit 18 to notify the earthquake information about the current position. And return to step S51.

  On the other hand, in the process of step S55, the control unit 11 calculates the predicted seismic intensity and the arrival delay time at all registered positions based on the position information at each point registered in the storage unit 15 and the received earthquake early warning. Calculate.

  In step S56, the earthquake information such as the predicted seismic intensity and the postponement time calculated by the control unit 11 for all the registered points is displayed on the display unit 17 and output via the audio output unit 18. As a result, the earthquake information for all registered positions is notified, and the process is terminated.

  As described above, according to the emergency disaster bulletin receiving device according to the present invention, when a plurality of points including the current position are registered as notification targets, a series of announcements for a registered point other than the current position are made a plurality of times. In this emergency earthquake early warning, only the final report, which is definite information, is used to perform the calculation only once, thereby minimizing the load of the prediction calculation process. As a result, even for devices such as embedded devices that do not have high processing capabilities, it is possible to target multiple points including the current position without interfering with the prediction calculation processing and notification processing for the current position, which is the original application. Therefore, the convenience for the user can be improved.

  In the above embodiment, the fixed telephone 1 identifies the target point for which the prediction calculation process is performed depending on whether the final earthquake early warning is received or the other emergency earthquake early warning is received. However, the present invention is not limited to this, and the target point on which the prediction calculation process is performed may be specified depending on whether or not the earthquake early warning is in a predetermined stage other than the final report, for example, the first earthquake early warning.

  Further, in the above embodiment, when the fixed telephone 1 receives the earthquake early warning other than the final report, the fixed telephone 1 registered as the first priority in the storage unit 15 is installed as a point where the prediction calculation process is performed. However, depending on the calculation processing capability of the control unit 11, a plurality of points may be targeted. In this case, a flag for identifying a plurality of target points may be stored in the storage unit 15 together with the position information of each point.

  In the above embodiment, the fixed telephone 1 is an IP telephone connected to the Internet network 4. However, the present invention is not limited to this, and the present invention is not limited to the fixed telephone or mobile telephone connected to a normal telephone line. It is also applicable to. In that case, the distribution of the emergency earthquake bulletin from the earthquake bulletin distribution server 3 is performed via a general telephone network or a wireless telephone network.
