Abstract

PROBLEM TO BE SOLVED: To enable operation resumption to be expedited and inconvenience to be reduced by separating a stop section and a deceleration section for a train 102 when an earthquake occurs.SOLUTION: An earthquake disaster prevention apparatus 200 stores an alarm condition table 292 in which a stop condition value and a deceleration condition value lower than the stop condition value are determined. A seismometer data receiving section 210 receives measurements from seismometers 101. An alarm necessity determination section 220 compares the measurements received by the seismometer data receiving section 210 with the stop condition value and the deceleration condition value determined in the alarm condition table 292. When the alarm necessity determination section 220 determines that the measurements are equal to or more than the value stop condition value, an earthquake alarm transmission section 230 transmits a stop request for the train 102 to a predetermined power supply device 111. When the alarm necessity determination section 220 determines that the measurements are less than the stop condition value and equal to or more than the deceleration condition value, the earthquake alarm transmission section 230 transmits a deceleration request for the train 102 to the predetermined power supply device 111.

Description

  The present invention relates to an earthquake occurrence notification device, an earthquake occurrence notification program, and an earthquake occurrence notification method for stopping or slowing down a train when an earthquake occurs, for example.

Many seismometers are installed nationwide by the Japan Meteorological Agency and the National Research Institute for Earth Science and Disaster Prevention.
In the event of an earthquake, the Japan Meteorological Agency estimates the epicenter and magnitude of the earthquake (magnitude, seismic intensity) using seismometers installed nationwide, and provides the estimated information as an emergency earthquake bulletin.

  In addition, railway companies have installed seismometers along the lines of each route, and use the seismometers installed independently for train operation management in the event of an earthquake.

The form which notifies the stop area and deceleration area of a vehicle based on the measured value measured by the seismometer is demonstrated.

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 the earthquake disaster prevention apparatus 200 has a seismometer 101 that has measured a large shake, a route section in which the seismometer 101 is installed is connected to a train 102 (shinkansen, but may be a conventional line). The power supply apparatus 111 is notified as a stop section. In addition, when there is a seismometer 101 that measures a small shake, the power supply device 111 is notified of the route section in which the seismometer 101 is installed as a deceleration section of the train 102.
For example, when the seismometer 101a and the seismometer 101b installed between Tokyo station and Shinagawa station measure a large shake, the earthquake disaster prevention apparatus 200 uses the power supply apparatus as a stop section of the train 102 between Tokyo station and Shinagawa station. 111 is notified. In addition, when the seismometer 101c and the seismometer 101d installed between Shinagawa Station and Shin-Yokohama Station measure a small shake, the earthquake disaster prevention apparatus 200 uses the power supply device as a deceleration section of the train 102 between Shinagawa Station and Shin-Yokohama Station. 111 is notified.
(3) The power supply apparatus 111 stops the train 102 traveling in the stop section notified from the earthquake disaster prevention apparatus 200, and decelerates the train 102 traveling in the deceleration section notified from the earthquake disaster prevention apparatus 200. .
For example, when the stop section “Tokyo Station−Shinagawa Station” is notified from the earthquake disaster prevention apparatus 200, the power supply apparatus 111 stops the train 102a traveling between Tokyo Station and Shinagawa Station. Moreover, when the deceleration section “Shinagawa Station−Shin Yokohama Station” is notified from the earthquake disaster prevention apparatus 200, the power supply apparatus 111 decelerates the train 102b traveling between Shinagawa Station and Shin Yokohama Station.

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 power supply devices 111.

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 power supply device 111 (an example of a terminal device or a train control device) controls the travel (normal travel, stop, or deceleration) of each train 102 by adjusting the amount of power supplied to each train 102 on each route ( Computer).

  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 route (the power supply device 111 thereof).

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 stop condition value (for example, acceleration, SI value or seismic intensity) and a deceleration condition value smaller than the stop condition value are set.
For example, the alarm condition table 292 is data in which a route section of the train 102, the seismometer 101, a stop condition value, and a deceleration condition value 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 seismometer 101.
That is, the seismometer data receiving unit 210 receives measurement values from each seismometer 101.

The alarm necessity determination unit 220 (an example of a notification condition determination unit) compares the measurement value received by the seismometer data reception unit 210 with the stop condition value and the deceleration condition value set in the alarm condition table 292.
The alarm necessity determination unit 220 determines whether the measured value is a value greater than or equal to the stop condition value, a value less than the stop condition value, a value greater than or equal to the deceleration condition value, and a value less than the deceleration condition value.

For example, the alarm necessity determination unit 220 compares the measured value with the stop condition value and the deceleration condition value as follows.
The alarm necessity determination unit 220 selects, from the measurement value data 291, the maximum measurement value within a predetermined collection time as the measurement value of the seismometer 101, and compares the selected measurement value with the stop condition value and the deceleration condition value.
The alarm necessity determination unit 220 acquires the stop condition value and the deceleration condition value corresponding to the seismometer 101 that has measured the measurement value received by the seismometer data reception unit 210 from the alarm condition table 292, and acquires the acquired stop condition. The value and deceleration condition value are compared with the measured value.

The earthquake warning transmission unit 230 (an example of an earthquake occurrence notification unit), when the alarm necessity determination unit 220 determines that the measured value is a value equal to or greater than the stop condition value, An example of a stop notification for notifying that the vehicle stop condition is satisfied is transmitted to the power supply device 111 of the route.
When the alarm necessity determination unit 220 determines that the measured value is less than the stop condition value and greater than or equal to the deceleration condition value, the earthquake alarm transmission unit 230 receives earthquake alarm data (vehicle deceleration) that instructs the train 102 to decelerate. An example of a deceleration notification for notifying that the condition is satisfied is transmitted to the power supply device 111 of the route.

For example, if the alarm necessity determination unit 220 determines that the measured value is equal to or greater than the stop condition value, the earthquake alarm transmission unit 230 indicates the route section (stop section) of the train 102 corresponding to the stop condition value. Send earthquake warning data including route section information.
Moreover, the earthquake warning transmission part 230 is a train corresponding to a stop condition value and a deceleration condition value, when the alarm necessity determination part 220 determines that the measured value is less than the stop condition value and a value greater than or equal to the deceleration condition value. Earthquake warning data is transmitted including section information indicating the 102 route sections (deceleration sections).

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 route (power supply device 111).

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

“Section” indicates a section (identifier) in the route.
The “control type” indicates “stop” or “deceleration” of the train 102.
The “alarm condition” includes one or 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 the measured value of the seismometer Sa is 150 or more, the alarm condition of item number 1 is satisfied. 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 2 is satisfied.
When the measured value of the seismometer Sa is 100 or more and less than 150 and the measured value of the seismometer Sb is less than 70, the alarm condition of item number 1 or item number 2 is not satisfied, but item number 4 The alarm condition of meet.

For example, when at least one of the alarm conditions from No. 1 to No. 3 is satisfied, the earthquake disaster prevention apparatus 200 is a route section (hereinafter referred to as “stop section”) in which the train 102 needs to stop between Tokyo Station and Shinagawa Station. ) Is transmitted to the power supply device 111 of the route.
Further, when any of the alarm conditions from No. 1 to No. 3 is not satisfied and at least one of the alarm conditions from No. 4 to No. 6 is satisfied, the earthquake disaster prevention apparatus 200 has a train 102 between Tokyo Station and Shinagawa Station. Is transmitted to the power supply device 111 of the relevant route to notify that it is a route section that needs to be decelerated (hereinafter referred to as “deceleration section”).

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 route from the earthquake disaster prevention storage unit 290, and performs the processing from S140 to S152 for each acquired alarm condition table 292 (not shown).

  In S140, the alarm necessity determination unit 220 acquires the “stop” alarm condition for each route section from the alarm condition table 292, and sets the condition value of each seismometer 101 for each acquired “stop” alarm condition in S130. The measured value of each selected seismometer 101 is compared.

  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 condition “Sa (150)” of item number 1 from the alarm condition table 292 illustrated in FIG. 3.
The alarm necessity determination unit 220 acquires the measurement value of the seismometer Sa specified by the alarm condition from the measurement value 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 (150) of the alarm condition.

The alarm necessity determination unit 220 acquires the alarm conditions “Sa (100)” and “Sb (70)” of item number 2 from the alarm condition table 292.
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 S150, the process proceeds to S151.

  In S151, the alarm necessity determination unit 220 determines whether or not each “deceleration” alarm condition is satisfied based on the comparison result in S150.

For example, when the measured value of the seismometer Sa is “110 (≧ 100)”, the alarm condition “Sa (100)” of item number 4 shown in FIG. 3 is satisfied. When the measurement value of the seismometer Sa is “90 (<100)”, the alarm condition “Sa (100)” of item number 4 is not satisfied.
When the measurement value of the seismometer Sa is “90 (≧ 80)” and the measurement value of the seismometer Sb is “60 (≧ 50)”, the alarm condition “Sa” of item number 5 shown in FIG. (80) "" Sb (50) "is satisfied. When the measurement value of the seismometer Sa is less than “80” or the measurement value of the seismometer Sb is less than “50”, the alarm condition of item number 5 is not satisfied.

When at least one of the “deceleration” alarm conditions is satisfied (YES), the process proceeds to S152. For example, if the alarm condition of item number 4, 5, or 6 shown in FIG.
If none of the “deceleration” alarm conditions is satisfied (NO), the process returns to S110.

  In S152, the earthquake warning transmission unit 230 generates earthquake warning data indicating a route section (deceleration section) that satisfies the “deceleration” warning condition, and uses the generated earthquake warning data to control the traveling of the train 102 on the route. It transmits to the supply apparatus 111 (similar to S142).

  For example, when at least one of the alarm conditions of item No. 4 to item No. 6 shown in FIG. 3 is satisfied, the earthquake alarm transmitter 230 transmits the earthquake alarm data indicating the deceleration section “Tokyo Station-Shinagawa Station” to the route. To the power supply apparatus 111.

The power supply device 111 that has received the earthquake warning data decelerates the train 102 traveling in the deceleration zone by reducing the amount of power supplied to the deceleration zone indicated in the earthquake warning data (for example, by lowering the voltage). .
By reducing the amount of power supplied to the deceleration section and decelerating the train 102, the safety of train operation can be ensured. Further, by continuing to supply power, it is possible to ensure the convenience of passengers until the restart of operation (operation of an air conditioner and use of a toilet), and it is possible to quickly restart the operation when the earthquake has subsided.

  After S152, the process returns to S110.

  By the earthquake disaster prevention method described above, the earthquake disaster prevention apparatus 200 determines the stop section and the deceleration section based on the measurement values of each seismometer 101, stops the train 102 traveling in the stop section, and travels in the deceleration section.
