Description

The present invention relates to a seismic motion warning device, a seismic motion warning system, and a seismic motion warning method.

It is known that buildings with a long natural period, such as high-rise buildings, may shake significantly due to long-period ground motion. A long-period ground motion is a long-period ground motion caused by a large-scale earthquake that occurs in the distance.

For example, in the 2011 Great East Japan Earthquake, it is known that high-rise buildings and other high-rise floors shook more than the ground shook in the Tokyo metropolitan area and Osaka, which are far from the epicenter. Such a large shaking may give a feeling of fear to residents of high-rise buildings or the like, or may cause damage such as breakdown to various facilities or the like.

On the other hand, a technique for predicting the occurrence of long-period ground motion and issuing a warning is known (see, for example, Patent Document 1).

Here, in a building such as a high-rise building, the influence of long-period ground motion (magnitude of shaking, etc.) may differ depending on the floor. For example, the lower floors may have a smaller effect (smaller shaking), while the higher floors may have a larger effect (larger shaking). Even on the same floor, the magnitude of shaking may differ depending on conditions such as altitude, eaves height of the building, number of floors above ground of the building, number of basement floors of the building, and the like.

However, in the above-mentioned prior art, the floor of a building such as a high-rise building is not considered. Therefore, for example, it was not possible to give a warning according to the floor after predicting the influence of long-period ground motion according to the floor of a high-rise building.

The disclosed technology aims to warn of the occurrence of long-period ground motion, depending on the location.

The disclosed technology is a seismic motion warning device that is connected to one or more devices and outputs a warning indicating the occurrence of a long-period ground motion to the device, and includes device observation data indicating the observation result of the seismic motion observed by the device. , The effect of long-period ground motion at the installation position based on the basic characteristic data indicating the characteristics of the installation position where the equipment is installed and the earthquake information data acquired from the earthquake information providing server connected to the earthquake motion warning device. When the analysis means for creating the analysis data for predicting the occurrence of the earthquake and the earthquake flash report data indicating the occurrence of the earthquake are received from the earthquake information providing server, the analysis data created by the analysis means and the earthquake flash report data are combined. Based on the prediction means that creates the prediction result data showing the prediction value of the influence of the long-period ground motion at the installation position, and the prediction value at the installation position based on the prediction result data created by the prediction means. When the determination means for determining whether or not the predetermined threshold value is exceeded and the determination means determine that the predicted value exceeds the predetermined threshold value, the warning is given to the device installed at the installation position. It has a warning means to output.

Depending on the position, it is possible to warn of the occurrence of long-period ground motion.

<Details of processing>
Next, the details of the processing of the seismic motion warning system 1 according to the present embodiment will be described.

<< Storage processing of earthquake information data 500 >>
First, a process of acquiring the earthquake information data 500 from the earthquake information providing system 30 and storing it in the storage unit 110 will be described with reference to FIG. FIG. 12 is a sequence diagram showing an example of the storage process of the earthquake information data 500.

First, the earthquake information request unit 102 of the earthquake motion warning device 10 creates a disaster prevention information data acquisition request, for example, at a predetermined date and time (step S1201).

Next, the communication unit 101 of the earthquake motion warning device 10 transmits the acquisition request of the disaster prevention information data created by the earthquake information request unit 102 to the earthquake information providing system 30 (step S1202). Then, the communication unit 101 receives the disaster prevention information data 510 returned from the earthquake information providing system 30.

Next, the earthquake information request unit 102 of the earthquake motion warning device 10 creates a request for acquiring long-period ground motion observation data (step S1203).

Next, the communication unit 101 of the seismic motion warning device 10 transmits a long-period ground motion observation data acquisition request created by the seismic information requesting unit 102 to the seismic information providing system 30 (step S1204). Then, the communication unit 101 receives the long-period ground motion observation data 520 returned from the earthquake information providing system 30.

Next, the data management unit 105 of the earthquake motion warning device 10 stores the disaster prevention information data 510 and the long-period ground motion observation data 520 received by the communication unit 101 in the storage unit 110 as the earthquake information data 500 (step S1205). .. As a result, the disaster prevention information data 510 and the long-period ground motion observation data 520 are stored in the storage unit 110 as the seismic information data 500.

If the disaster prevention information data 510 and the long-period ground motion observation data 520 are not returned from the seismic information providing system 30, the data management unit 105 does not have to perform the process of step S1205.

<< Storage processing of equipment observation data 400 >>
Next, a process of storing the device observation data 400 received from the device 20 in the storage unit 110 will be described with reference to FIG. FIG. 13 is a sequence diagram showing an example of storage processing of the device observation data 400.

First, when a shaking (earthquake motion) occurs due to an earthquake, the observation unit 201 of the device 20 observes the shaking (step S1301). That is, the observation unit 201 measures the acceleration having three directions of the x-axis direction, the y-axis direction, and the z-axis direction as components by the acceleration sensor 27.

Next, the observation unit 201 of the device 20 creates the device observation data 400 indicating the observation result at the installation point of the device 20 (step S1302).

Next, the communication unit 203 of the device 20 transmits the device observation data 400 created by the observation unit 201 to the seismic motion warning device 10 (step S1303). In this way, the device 20 observes the shaking (earthquake motion) due to the earthquake and transmits the device observation data 400 indicating the observation result at the installation point of the device 20 to the seismic motion warning device 10.

When the data management unit 105 of the seismic motion warning device 10 receives the equipment observation data 400 by the communication unit 101, the data management unit 105 stores the equipment observation data 400 in the storage unit 110 (step S1304). As a result, the instrument observation data 400 is stored in the storage unit 110.

<< Processing to create analysis data 700 >>
Next, the process of creating the analysis data 700 based on the basic characteristic data 300, the instrument observation data 400, and the earthquake information data 500 stored in the storage unit 110 will be described with reference to FIG. FIG. 14 is a flowchart showing an example of the process of creating the analysis data 700. The process of creating the analysis data 700 shown in FIG. 14 is executed at preset predetermined time intervals (for example, weekly or monthly) or at preset dates and times.

First, the data management unit 105 of the earthquake motion warning device 10 acquires the earthquake information data 500 from the storage unit 110 (step S1401).

Next, the data management unit 105 of the seismic motion warning device 10 acquires one basic characteristic data 300 out of the basic characteristic data 300 stored in the storage unit 110 (step S1402).

Next, the data management unit 105 of the seismic motion warning device 10 acquires the equipment observation data 400 corresponding to the acquired basic characteristic data 300 from the storage unit 110 (step S1403). That is, the data management unit 105 acquires the equipment observation data 400 including the same installation point code as the acquired basic characteristic data 300 from the storage unit 110.

Next, the analysis unit 103 of the seismic motion warning device 10 creates analysis data 700 based on the acquired basic characteristic data 300, equipment observation data 400, and seismic information data 500 (step S1404). That is, the analysis unit 103 sets the virtual epicenter based on the basic characteristic data 300, the equipment observation data 400, and the earthquake information data 500, and then installs the installation point code included in the basic characteristic data 300. The analysis data 700 is created by calculating the predominant period, the natural period, the attenuation constant, the distance attenuation rate, the surface layer ground amplification factor, the regression coefficient, and the like at the points.

Next, the data management unit 105 of the seismic motion warning device 10 stores the analysis data 700 created by the analysis unit 103 in the storage unit 110 (step S1405). As a result, the analysis data 700 corresponding to the basic characteristic data 300 acquired by the data management unit 105 is stored in the storage unit 110.

Next, the data management unit 105 of the seismic motion warning device 10 determines whether or not there is the next basic characteristic data 300 (step S1406). That is, the data management unit 105 determines whether or not there is basic characteristic data 300 that has not yet been acquired among the basic characteristic data 300 stored in the storage unit 110.

If it is determined in step S1406 that the next basic characteristic data 300 does not exist, the seismic motion warning device 10 ends the process.

On the other hand, when it is determined in step S1406 that the next basic characteristic data 300 is available, the data management unit 105 of the seismic motion warning device 10 acquires the next basic characteristic data 300 from the storage unit 110 (step S1407). Then, the seismic motion warning device 10 performs the processes after step S1403.

As a result, analysis data 700 is created for each basic characteristic data 300 (that is, for each installation point code) and stored in the storage unit 110. If the analysis data 700 including the same installation point code is already stored in the storage unit 110, the data management unit 105 may overwrite the analysis data 700. However, in this case, the data management unit 105 may store the analysis data 700 as different analysis data 700 in the storage unit 110 without overwriting, for example, by adding a creation date.

≪Forecasting and warning processing of long-period ground motion≫
Next, when the Earthquake Early Warning data 900 is transmitted from the earthquake information providing system 30, the process of predicting the influence of long-period ground motion and outputting a warning from the device 20 according to the predicted influence is shown in FIG. This will be described with reference to 15. FIG. 15 is a sequence diagram showing an example of prediction of long-period ground motion and warning processing.

First, when an earthquake of a predetermined scale or larger occurs, for example, the earthquake information providing system 30 transmits emergency earthquake breaking news data 900 including information on the earthquake to the earthquake motion warning device 10 (step S1501).

Here, the details of the earthquake early warning data 900 transmitted from the earthquake information providing system 30 will be described with reference to FIG. FIG. 16 is a diagram showing an example of Earthquake Early Warning data 900.

As shown in FIG. 16, the Earthquake Early Warning data 900 includes the earthquake occurrence time, the epicenter code, the earthquake scale, the latitude / longitude of the epicenter, the epicenter depth, the expected area code, the expected seismic intensity, and the forecast. Includes arrival time.

The earthquake occurrence time is the time when the earthquake occurred. The epicenter code is identification information that identifies the epicenter of an earthquake that has occurred (that is, a point on the surface directly above the epicenter). The magnitude of an earthquake is an index value (magnitude) that indicates the magnitude of the energy generated by an earthquake that has occurred.

The latitude and longitude of the epicenter are the latitude and longitude of the epicenter. The epicenter depth is the depth of the epicenter in the earthquake that occurred. The predicted area code is information that identifies the area (for example, a city, ward, town, or village) for which the seismic intensity is predicted. The predicted seismic intensity is the predicted seismic intensity in the area indicated by the predicted area code. The predicted arrival time is the predicted time when the main movement arrives at the area indicated by the predicted area code.

As described above, the Earthquake Early Warning data 900 is data including various information regarding earthquakes observed by, for example, the Japan Meteorological Agency.

Return to FIG. When the data management unit 105 of the earthquake motion warning device 10 receives the earthquake early warning data 900 by the communication unit 101, the data management unit 105 acquires the analysis data 700 from the storage unit 110 (step S1502).

Next, the prediction unit 104 of the seismic motion warning device 10 predicts the influence of long-period ground motion at the installation point indicated by the installation point code included in the analysis data 700 based on the Earthquake Early Warning data 900 and the analysis data 700. To do. Then, the prediction unit 104 creates the prediction result data 800 indicating the prediction result (step S1503). That is, the prediction unit 104 creates the prediction result data 800 by calculating the absolute velocity response spectrum predicted value at the installation point based on the Earthquake Early Warning data 900. The absolute velocity response spectrum predicted value can be calculated by performing multiple regression analysis using the regression coefficient included in the analysis data 700.

Next, the data management unit 105 of the seismic motion warning device 10 stores the prediction result data 800 created by the prediction unit 104 in the storage unit 110 (step S1504).

Next, the warning determination unit 106 of the seismic motion warning device 10 warns the device 20 corresponding to the prediction result data 800 based on the prediction result data 800 and the threshold setting data 600 corresponding to the prediction result data 800. It is determined whether or not to notify (step S1505).

That is, for each prediction result data 800, the warning determination unit 106 sets the absolute velocity response spectrum predicted value included in the prediction result data 800 to the absolute velocity response spectrum threshold value included in the threshold setting data 600 having the same installation point code. Determine if it exceeds. Then, when the absolute velocity response spectrum predicted value exceeds the absolute velocity response spectrum threshold value, the warning determination unit 106 determines that the warning is notified to the device 20 at the installation point indicated by the installation point code.

If there is no device 20 determined to notify the warning in step S1505, the seismic motion warning device 10 ends the process.

On the other hand, in step S1505, when the device 20 determined to notify the warning exists, the warning notification unit 107 of the seismic motion warning device 10 creates a warning notification (step S1506).

The warning notification unit 107 may create a warning notification according to the difference between the predicted absolute velocity response spectrum value and the absolute velocity response spectrum threshold value. For example, when the difference between the absolute velocity response spectrum predicted value and the absolute velocity response spectrum threshold value is larger than a predetermined value, the warning notification unit 107 creates a warning notification for outputting a warning sound and turning on the warning light. .. On the other hand, for example, when the difference between the absolute velocity response spectrum predicted value and the absolute velocity response spectrum threshold value is equal to or less than a predetermined value, the warning notification unit 107 creates a warning notification for outputting a warning sound. Is.

Next, the communication unit 101 of the seismic motion warning device 10 transmits the warning notification created by the warning notification unit 107 to the device 20 determined to notify the warning by the warning determination unit 106 (step S1507).

When the warning output unit 202 of the device 20 receives the warning notification by the communication unit 203, it outputs a warning indicating the occurrence of long-period ground motion (step S1508). That is, the warning output unit 202 outputs, for example, a warning sound from the alarm 28 as a warning indicating the occurrence of long-period ground motion. Further, the warning output unit 202 may output a message such as "an earthquake has occurred. Please prepare for a large shaking" from the alarm 28 as a warning indicating the occurrence of long-period ground motion. Further, the warning output unit 202 may turn on a warning light or the like as a warning indicating the occurrence of long-period ground motion.

The warning output unit 202 may, for example, send an e-mail containing the message to a pre-registered e-mail address, or may send a fax containing the message to a pre-registered telephone number. ..
