Embodiment 1 FIG.
A mode for determining whether or not to notify the occurrence of an earthquake based on a plurality of measurement values measured by a plurality of seismometers and correctly notifying the occurrence of the earthquake will be described.

FIG. 1 is a schematic diagram of an earthquake disaster prevention system 100 according to the first embodiment.
The outline | summary of the earthquake disaster prevention system 100 in Embodiment 1 is demonstrated based on FIG.

(1) In the earthquake disaster prevention system 100, the plurality of seismometers 101a-d installed in various places measure the magnitude of ground shaking and transmit the measured value to the earthquake disaster prevention apparatus 200.

(2) When a plurality of seismometers 101 measure a shake greater than or equal to a predetermined magnitude, the earthquake disaster prevention apparatus 200 notifies the railway operator terminal 110 of a route section in an area where the shake greater than or equal to a given magnitude is measured. To do.
For example, when the seismometer 101a and the seismometer 101b installed between Tokyo station and Kawasaki station measure a shake of a predetermined magnitude or larger, the earthquake disaster prevention apparatus 200 determines the route section “between Tokyo station and Kawasaki station”. Notify the railway operator terminal 110.

(3) The railway operator terminal 110 stops (or decelerates) the train 102 traveling on the route section notified from the earthquake disaster prevention apparatus 200.
For example, when the “disaster between Tokyo and Kawasaki” is notified from the earthquake disaster prevention apparatus 200, the railway operator terminal 110 stops (or decelerates) the train 102a traveling between “between Tokyo and Kawasaki”.

FIG. 2 is a configuration diagram of the earthquake disaster prevention system 100 according to the first embodiment.
The structure of the earthquake disaster prevention system 100 in Embodiment 1 is demonstrated based on FIG.

  The earthquake disaster prevention system 100 includes an earthquake disaster prevention device 200, a plurality of seismometers 101, and a plurality of railway operator terminals 110.

A plurality of seismometers 101 are installed throughout the country.
For example, seismometers installed in various places by the Japan Meteorological Agency or National Research Institute for Earth Science and Disaster Prevention, or seismometers installed by railway companies along the lines of their own lines may be used as the plurality of seismometers 101.

  Each seismometer 101 measures the magnitude of shaking of the ground at the place where it is installed (for example, acceleration, SI (Spectrum Intensity) value or seismic intensity) at a predetermined measurement cycle (for example, 1/100 second interval), The seismometer data representing each measured value is transmitted to the earthquake disaster prevention apparatus 200 at a predetermined transmission cycle (for example, every 1 second).

  The railway operator terminal 110 (an example of a terminal device) is an apparatus (computer) for managing and controlling the traveling of each train 102 by each railway operator.

  The earthquake disaster prevention apparatus 200 (an example of an earthquake occurrence notification apparatus) includes a seismometer data reception unit 210, an alarm necessity determination unit 220, an earthquake alarm transmission unit 230, and an earthquake disaster prevention storage unit 290.

The earthquake disaster prevention storage unit 290 (an example of a condition value storage unit and a measurement value storage unit) stores data used by the earthquake disaster prevention apparatus 200.
For example, the earthquake disaster prevention storage unit 290 stores measurement value data 291 associated with each seismometer 101 and an alarm condition table 292 associated with each railway operator (its railway operator terminal 110).

The measured value data 291 is data in which measured values in the seismometer data received by the seismometer data receiving unit 210 within a predetermined collection time (for example, 30 minutes) are set.
That is, the measurement value data 291 is data including measurement values measured by the seismometer 101 within a predetermined collection time.

The alarm condition table 292 is data in which a plurality of condition values (for example, acceleration, SI value, or seismic intensity) are set.
For example, the alarm condition table 292 is data in which a plurality of seismometers 101 are associated with a plurality of condition values. Further, for example, the alarm condition table 292 is data in which a route section of the train 102, a plurality of seismometers 101, and a plurality of condition values are associated with each other.

The seismometer data receiving unit 210 (an example of a measurement value receiving unit) receives seismometer data periodically transmitted from each of the plurality of seismometers 101.
That is, the seismometer data receiving unit 210 receives a plurality of measurement values from the plurality of seismometers 101.

  The alarm necessity determination unit 220 (an example of a notification condition determination unit) compares a plurality of measurement values received by the seismometer data reception unit 210 with a plurality of condition values set in the alarm condition table 292, and It is determined whether or not a predetermined alarm condition (an example of a notification condition) is satisfied based on the comparison result.

For example, the alarm necessity determination unit 220 compares a plurality of measured values with a plurality of condition values as follows.
The alarm necessity determination unit 220 acquires a condition value corresponding to the seismometer 101 that measured the measurement value from the alarm condition table 292, and compares the acquired condition value with the measurement value.
The alarm necessity determination unit 220 selects, from each measurement value data 291, a maximum measurement value within a predetermined collection time as a measurement value of each of the plurality of seismometers 101, Compare

For example, the alarm necessity determination unit 220 determines whether the alarm condition is satisfied as follows.
The alarm necessity determination unit 220 determines that the alarm condition is satisfied when all of the plurality of measurement values are larger than the condition value.

The earthquake warning transmission unit 230 (an example of an earthquake occurrence notification unit) receives earthquake alarm data (an example of an earthquake occurrence notification for notifying an earthquake occurrence) when the alarm necessity determination unit 220 determines that the alarm condition is satisfied. Transmit to the railway operator terminal 110 of the operator.
For example, the earthquake warning transmission unit 230 includes section information indicating train route sections corresponding to a plurality of condition values compared with a plurality of measurement values when the alarm necessity determination unit 220 determines that the alarm condition is satisfied. Send earthquake warning data.

FIG. 3 is a diagram illustrating an example of the alarm condition table 292 according to the first embodiment.
An example of the alarm condition table 292 according to Embodiment 1 will be described with reference to FIG.

  For example, the alarm condition table 292 is provided for each railway operator (railway operator terminal 110).

  The alarm condition table 292 is data in which “route”, “section”, and “alarm condition” are associated with each other.

“Route” indicates a route name (identifier) of the railway operator.
“Section” indicates a section (identifier) in the route.
The “alarm condition” includes a plurality of “individual conditions” in which seismometers (identifiers) are associated with condition values. The alarm condition is met when all individual conditions are met. One or more alarm conditions are set for one section.

For example, when satisfying at least one of the alarm condition of item No. 1 and the alarm condition of item No. 2, the earthquake disaster prevention apparatus 200 has a train 102 between Tokyo station and Kawasaki station on the T line operated by the railway operator J. Earthquake warning data for notifying that the route section that requires traveling control (hereinafter also referred to as a warning section or a disaster prevention section) is transmitted to the railway operator terminal 110 of the railway operator J.
When the measured value of the seismometer Sa is 100 or more and the measured value of the seismometer Sb is 70 or more, the alarm condition of item number 1 is satisfied. In addition, when the measured value of the seismometer Sa is 80 or more, the measured value of the seismometer Sb is 60 or more, and the measured value of the seismometer Sc is 70 or more, the alarm of item number 2 Meet the conditions.

For example, when a trench-type earthquake occurs and a large measured value is detected by a seismometer near the coast far from the track, it is predicted that dangerous shaking will occur near the track inland. For this reason, the condition value of the seismometer 101 at a point away from the track is set higher than the condition value of the seismometer 101 along the track. In this case, the condition value is higher as the seismometer 101 is farther from the track.
However, in order to stop (or decelerate) the train 102 when an earthquake occurs at a relatively close point from the track, the condition value of the seismometer 101 along the track is higher than the condition value of the seismometer 101 at a point far from the track. It may be set. In this case, the condition value is higher as the seismometer 101 is closer to the track.
In addition, the condition value of each seismometer 101 may be set regardless of the distance from the track (or considering the distance from the track) based on the ease of ground shaking and empirical rules.

FIG. 4 is a flowchart illustrating the earthquake disaster prevention method of the earthquake disaster prevention apparatus 200 according to the first embodiment.
The earthquake disaster prevention method of the earthquake disaster prevention apparatus 200 in Embodiment 1 is demonstrated based on FIG.

In S110, each seismometer 101 measures the magnitude (for example, acceleration) of the ground at the place where it is installed at a predetermined measurement cycle (for example, every 1/100 second), Seismometer data representing the measurement time at which each measurement value is measured is transmitted to the earthquake disaster prevention apparatus 200 at a predetermined transmission cycle (for example, at intervals of 1 second).
The seismometer data receiving unit 210 receives seismometer data periodically transmitted from each seismometer 101.
It progresses to S120 after S110.

In S120, the seismometer data receiving unit 210 acquires each measurement value set in the seismometer data and the measurement time of each measurement value from the seismometer data of each seismometer 101 received in S110. The measurement value and the measurement time of each measurement value are associated and set in the measurement value data 291 of the seismometer 101 in addition.
It progresses to S130 after S120.

In S <b> 130, the alarm necessity determination unit 220 selects one measurement value from the measurement value data 291 of each seismometer 101 one by one. That is, the alarm necessity determination unit 220 selects one measurement value for each seismometer 101.
For example, the alarm necessity determination unit 220 acquires a plurality of measurement values measured from the current time to a past time before a predetermined collection time (for example, 30 seconds before) from the measurement value data 291 of each seismometer 101. Then, the maximum measurement value is selected from the plurality of acquired measurement values. However, the alarm necessity determination unit 220 may select the latest measured value.
It progresses to S140 after S130.

  The alarm necessity determination unit 220 acquires the alarm condition table 292 for each railway company from the earthquake disaster prevention storage unit 290, and performs the processes of S140 and S150 for each acquired alarm condition table 292 (not shown).

  In S140, the alarm necessity determination unit 220 acquires the alarm condition for each route section from the alarm condition table 292, and the condition value of each seismometer 101 and the measurement of each seismometer 101 selected in S130 for each acquired alarm condition. Compare the value.

For example, the alarm necessity determination unit 220 compares the condition value and the measurement value of each seismometer 101 as follows.
The alarm necessity determination unit 220 acquires the alarm conditions “Sa (100)” and “Sb (70)” of item number 1 from the alarm condition table 292 shown in FIG.
The alarm necessity determination unit 220 acquires the measured values of the seismometer Sa and the seismometer Sb specified by the alarm condition from the measured values of each seismometer 101 selected in S130.
The alarm necessity determination unit 220 compares the measured value of the seismometer Sa with the condition value (100) of the alarm condition, and compares the measured value of the seismometer Sb with the condition value (70) of the alarm condition.

  After S140, the process proceeds to S150.

  In S150, the alarm necessity determination unit 220 determines whether or not each alarm condition is satisfied based on the comparison result in S140. The alarm condition is satisfied when the measured value is greater than or equal to the condition value for all of the plurality of seismometers 101 indicated by the alarm condition, and the alarm condition is determined when the measured value of at least one of the seismometers 101 is less than the condition value. Do not meet.

For example, when the measurement value of the seismometer Sa is “110 (≧ 100)” and the measurement value of the seismometer Sb is “80 (≧ 70)”, the alarm condition “Sa of item number 1 shown in FIG. (100) "" Sb (70) "is satisfied.
On the other hand, when the measured value of the seismometer Sa is less than “100” or when the measured value of the seismometer Sb is less than “70”, the alarm condition of item number 1 is not satisfied.

When at least one of the alarm conditions is satisfied (YES), the process proceeds to S160.
If neither alarm condition is satisfied (NO), the process returns to S110.

  In S160, the earthquake warning transmission unit 230 generates earthquake warning data indicating a route section that satisfies the warning condition, and transmits the generated earthquake warning data to the railway operator terminal 110 of the railway operator that operates the route section. .

  For example, an address table in which the address of each railway operator terminal 110 is set is stored in the earthquake disaster prevention storage unit 290 in advance. The earthquake warning transmission unit 230 acquires the address of the railway operator terminal 110 corresponding to the alarm condition table 292 including the alarm condition from the address table, and transmits the earthquake alarm data using the acquired address as a transmission destination address.

  For example, when at least one of the alarm condition of item No. 1 and the alarm condition of item No. 2 shown in FIG. 3 is satisfied, the earthquake alarm transmission unit 230 displays an earthquake alarm indicating the T line between Tokyo station and Kawasaki station. Data is transmitted to the railway operator terminal 110 of the railway operator J.

Each railway operator terminal 110 manages the operation of each train 102. Hereinafter, data indicating a route section in which each train 102 is traveling is referred to as train management data.
The railway operator terminal 110 that has received the earthquake warning data specifies the train 102 that is traveling in the route section indicated by the earthquake warning data based on the train management data, and controls the traveling of the specified train 102.
For example, the railway operator terminal 110 notifies the cab device of the identified train 102 of a stop command (or deceleration command), and the cab device sounds an alarm lamp or an alarm sound that informs the stop command (or deceleration command) to drive. The person stops (or decelerates) the train 102 at a safe point.
The railway operator terminal 110 may stop (or decelerate) the train 102 (for example, the Shinkansen) by controlling the power supply device of the route. The power supply device is a device that controls the amount of power supplied to the train 102.

  After S160, the process returns to S110.

  By the earthquake disaster prevention method described above, the earthquake disaster prevention apparatus 200 stops (or decelerates) the train 102 running on a specific route section when a plurality of seismometers 101 measure a measured value equal to or greater than a predetermined condition value. .

  An application example of the earthquake disaster prevention system 100 described above will be described below.

(1) The alarm necessity determination unit 220 may determine that the alarm condition is satisfied when at least a predetermined number (two or more values) of individual conditions among three or more individual conditions included in the alarm condition is satisfied. .
For example, even if the measured value of the seismometer Sa is less than “80” with respect to the alarm condition “Sa (80)”, “Sb (60)”, “Sc (70)” of item number 2 shown in FIG. When the measured value of the seismometer Sb is “60” or more and the measured value of the seismometer Sc is “70” or more, the alarm necessity determination unit 220 determines that the alarm condition of item number 2 is satisfied.

(4) The earthquake disaster prevention apparatus 200 may transmit the earthquake warning data to a terminal apparatus other than the railway operator terminal 110.
For example, the earthquake disaster prevention apparatus 200 identifies the train 102 running on a route section that satisfies the alarm condition instead of the railway operator terminal 110, and transmits the earthquake alarm data to the identified cab device of the train 102 for operation. The trainer may be prompted to stop the train 102 or the like. Moreover, the earthquake disaster prevention apparatus 200 may stop the train 102 by transmitting earthquake alarm data to the power supply apparatus (train control apparatus).
Further, the earthquake disaster prevention apparatus 200 may transmit the earthquake alarm data to a management terminal provided in a building or a commercial facility.

(5) The earthquake disaster prevention system 100 may control vehicles other than the train 102 such as buses (automobiles) and amusement park vehicles. The earthquake disaster prevention device 200 controls the operation of the vehicle by transmitting earthquake alarm data to a control device that controls the vehicle to be controlled.

  In the first embodiment, for example, the earthquake disaster prevention system 100 having the following effects has been described.

The earthquake disaster prevention apparatus 200 determines whether or not an earthquake occurrence notification (earthquake alarm) is necessary based on the measured values of the plurality of seismometers 101.
As a result, it is possible to prevent an erroneous detection of the earthquake and correctly notify the occurrence of the earthquake.

For example, it is possible to prevent occurrence of confusion by notifying the occurrence of an earthquake when a certain seismometer breaks down and outputs an abnormal measurement value, or when a shake other than an earthquake is detected due to a lightning strike or the like. As a specific example, it is possible to prevent the operation of the train 102 from being hindered by stopping the train 102 that does not need to be stopped.
Also, if the epicenter is a shallow point far from the railroad, even if it shakes greatly near the epicenter, it does not shake much near the railroad far from the epicenter. In such a case, the seismometer 101 near the epicenter measures a large shake, but since the seismometer 101 near the track measures only a small shake, the earthquake disaster prevention apparatus 200 stops the train 102 that does not need to be stopped. I will not let you. Thereby, the operation of the train 102 is not hindered.
