[Prior art]
By providing warning information that warns of the arrival of a large earthquake before a major earthquake arrives, human and material damage can be minimized. Therefore, various attempts have been made in the past to detect warnings of earthquakes and issue alarms.
However, most of these earthquake warning systems are still at the experimental level, and few have been put into practical use. In addition to reliably detecting the arrival of earthquakes, we have provided warning information to warn of the arrival of earthquakes. There is still no earthquake warning system that can be reliably transmitted to people and individuals.

A system for estimating the scale and epicenter has been developed and is being put into practical use as a safety measure for railways. For example, the Japan Railway Technical Research Institute has reported the alarm system “Yuredas” (see JSCE Proceedings I [Reprint], JOURNAL OF STRUCTURAL MECHANICS AND EARTHQUAKE ENGINEERING No.531 / I-34 1996-1). .
In this alarm system “Yuredas”, it is possible to detect the initial motion of the P wave of the earthquake, estimate the magnitude, epicenter position, and depth, and send the alarm to the required area within 4 seconds.

DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, the earthquake warning system according to the present inventionThe fruitThe embodiment will be described.
  First,Reference example of earthquake warning systemWill be described.
  As shown in Figure 1Reference exampleThe earthquake warning system 1000 of the observation device 1 for observing earthquakes by fixed point observation0 andThe analysis device 20 that analyzes the observation information of the earthquake observed by the earthquake observation device 10, the alarm device 30 that sends out a predetermined earthquake alarm according to the analysis result of the analysis device 20, and the warning device 30 Line 4 for transmitting earthquake warnings0 and, And an operating facility 50 that performs a predetermined operation in response to an earthquake alarm received via the line 40.
[0012]
  The observation device 10 detects various characteristics such as the period and amplitude of the P wave transmitted by the occurrence of the earthquake, and the incident direction.SaThe detection signals from these sensors are output to the analysis device 20 via the dedicated line 10A.
  The analysis device 20 includes an information processing device such as a personal computer or a workstation, and an estimation unit 20 that estimates the location and size of the earthquake.A andThe determination unit 20 that determines the necessity of an alarm for the operating facility 50 from the estimation result of the estimation unit 20A.B andHave
  The estimation unit 20 </ b> A estimates the location and size of the earthquake based on detection signals detected by various sensors of the earthquake observation apparatus 10. For example, the magnitude (magnitude) of the earthquake is estimated from the period of the P wave, and the orientation of the epicenter is estimated based on the incident angle of the P wave. Furthermore, the epicenter distance is estimated from the maximum value of the P wave initial motion. Then, the location of the epicenter can be estimated from the orientation of the epicenter and the epicenter distance.
[0013]
Moreover, the determination part 20B determines separately the necessity of the warning with respect to the some operation equipment 50 from the estimation result of the estimation part 20A, and determines the presence or absence of the alarm to each operation equipment 50, and the alarm content.
In other words, in this example, the plurality of operating facilities 50 are located at different locations and have different operating targets, and therefore the necessity of alarm is determined under different conditions.
[0014]
Therefore, in the determination part 20B, the necessity for the warning with respect to the some operating equipment 50 is determined by parallel processing from a different estimation condition from the estimation result of the estimation part 20A.
For example, the degree of seismic intensity at the location of each operating facility 50 is determined from the magnitude of the earthquake and the location of the epicenter, and it is determined whether an alarm is necessary. Moreover, the transmission time (margin time) of the earthquake with respect to each operation equipment 50 is calculated from the location and the epicenter position of each operation equipment 50.
Then, the determination unit 20 </ b> B creates earthquake alarm data corresponding to each operating facility 50 based on such determination, and sends it to the alarm device 30.
[0015]
The determination in the determination unit 20B can be performed by setting a registration table in which the determination conditions for each operating facility 50 are registered in advance in the memory and referring to the registration table.
Further, since the estimation in the estimation unit 20A includes a certain error, the error included in the estimation in the estimation unit 20A is determined from, for example, past statistical data in the determination of the margin time or the like in the determination unit 20B Based on the above, it is determined that the maximum margin is included, and the determination is made so that the actual margin time is not smaller than the estimated margin time, for example.
[0016]
Further, the alarm device 30 realizes alarm transmission means for generating earthquake alarm information based on the earthquake alarm data from the determination unit 20B and transmitting it to each operating facility 50 via the line 40. The alarm device 30 includes a database 52 that stores connection data necessary for accessing each operating facility 50 in order to access each operating facility 50 via the line 40.
The line 40 can be a dedicated line or a public line. Moreover, not only a wired line but a part including a wireless line may be included. Further, the line 40 may include the Internet.
[0017]
The operation facility 50 receives the earthquake warning information transmitted from the warning device 30 via the line 40, and executes a predetermined earthquake countermeasure operation based on the content of the earthquake warning information.
Here, the operation facility 50 is a device whose original function is hindered by the arrival of an earthquake, for example, a computer, a financial system, an elevator facility, a factory facility, or the like.
The earthquake countermeasure operation is a data maintenance operation in a computer or a financial system, an emergency stop operation to the nearest floor in an elevator facility, or an emergency stop operation of a machine in a factory facility.
Further, the operating facility 50 includes an alarm output unit 52 that executes a predetermined alarm operation, and performs an alarm operation to warn of the arrival of an earthquake based on the content of the earthquake alarm information.
[0018]
The alarm output unit 52 can be composed of a speaker, a display panel, a normal telephone, a private telephone, a facsimile, a display panel, and the like. The warning operation is an operation of making a warning announcement using a speaker, warning of an earthquake coming by telephone or facsimile, or displaying a warning on a display panel.
[0019]
As the alarm output unit 52, a wireless transmitter and a wireless receiver can be used. In this case, the wireless transmitter is configured to output a predetermined warning signal as a wireless signal based on the earthquake warning information received via the line 40, and the wireless receiver receives the warning signal, so that the voice is received. If the radio receiver is carried by an operator in the operating facility, an alarm will be triggered by the alarm action of the radio receiver. It is possible to minimize human damage by quickly knowing and taking action such as evacuation.
For example, a commercially available radio can be used as the radio receiver, and a radio transmitter capable of transmitting a radio signal receivable by the radio as a predetermined alarm signal can be provided.
[0020]
