Description

The present invention relates to an earthquake monitoring system for monitoring an earthquake,
In particular, it relates to an earthquake monitoring system that can also create simulation data for training observers.

[Conventional technology]

Conventionally, an earthquake monitoring system has a telemeter as a detection means for detecting an earthquake waveform, a waveform recording means for recording the earthquake waveform from this telemeter as an actual earthquake waveform data on a recording medium, and an earthquake waveform from the telemeter in real time. It is provided with an earthquake monitoring means for monitoring and outputting the monitoring result to a pen recorder and recording the monitoring result data in the recording medium.

By the way, in the earthquake monitoring system having such a configuration, simulation data for training the observer when various kinds of earthquakes occur is created by the procedure shown in FIG. That is, the actual seismic waveform detected by the telemeter is a pen recorder (waveform recording means).
The actual seismic waveform recorded on the recording paper (recording medium) is copied onto the copying paper to collect seismic waveforms of various amplitudes. Next, the seismic waveforms copied above are combined according to the earthquake power supply and magnitude set for training, and the seismic waveforms are clipped to create seismic waveform records for training. Then, at the time of training, the seismic waveform record for the training is used, and it is read by the digitizer and given to the processing device to calculate the power supply and the like.

[Problems to be Solved by the Invention]

However, in the conventional earthquake monitoring system, the output of the seismic waveform is the pen recorder output, and the pen recorder must always be on standby for the actual earthquake, and the seismic waveform for training can be output in real time. In addition, when the past seismic waveform output is used, the output is the same as the pen recorder output, and there is a problem that it is not easy to change the amplitude by changing the amplitude.

The present invention has been made to solve the above-mentioned problems, and it is possible to appropriately select a previously selected actual earthquake waveform without interrupting the continuous earthquake monitoring process performed in real time online. The purpose is to provide an earthquake monitoring system that can easily create and display in real time a training seismic waveform whose amplitude has been converted to a large scale, and can perform training by the same operation as the actual seismic monitoring process. To do.

Example of Invention

FIG. 1 is a configuration block diagram of an earthquake monitoring system according to an embodiment of the present invention. In the figure, 1 is a telemeter as a detecting means for detecting the seismic waveform, 2 is a waveform recording means for recording the seismic waveform from the telemeter 1 as actual seismic waveform data 4 on a recording medium, and 3 is the seismic waveform from the telemeter 1. It is an earthquake monitoring means for monitoring in real time and displaying the monitoring result on the terminal device 5 and recording the monitoring result data 6 in a recording medium. 7 is an arbitrary seismic waveform extracted from the actual seismic waveform data 4 and the seismic waveform is multiplied by a training waveform creation parameter (a scaling factor parameter for enlarging / reducing the amplitude of the waveform) input from the terminal device 8. The seismic waveform data 9 for training of the observer is created, the monitoring result data corresponding to the arbitrarily selected seismic waveform is extracted from the monitoring result data 6, and the training monitoring result corresponding to the seismic waveform data 9 for training. It is a training data creating means for creating the data 10. 11

A training seismic monitoring means for displaying a training seismic waveform on the terminal device 12 in real time using 10.

Next, the operation will be described. The seismic waveform constantly input from the telemeter 1 is recorded in the recording medium as the actual seismic waveform data 4 by the automatically operating waveform recording means 2. The input seismic waveform is given to the seismic monitoring means 3 for analysis, etc., and the result is displayed on the terminal device 5 (graphic display of the seismic monitoring means) and also as actual seismic monitoring result data 6 on a recording medium. It will be recorded. In the training seismic waveform creation process, the training data creation means 7 extracts an arbitrary seismic waveform (seismic waveform selected by the observer) from the past actual seismic waveform data 4 and inputs the seismic waveform from the terminal device 8. The training seismic waveform data 9 is created by multiplying the scale factor parameters and the like (parameters selected by the observer). The training seismic waveform data 9 has its amplitude expanded or contracted according to a magnification parameter or the like. Further, the training data creation means 7 creates the training monitoring result data 10 by modifying the actual earthquake monitoring result data 6 according to the amplitude change of the training earthquake waveform data 9 and the training implementation date and time. The training earthquake monitoring means 11 displays the training earthquake waveform on the terminal device 12 in real time using the training earthquake waveform data 9 and the training monitoring result data 10. The training earthquake monitoring process operates in the same manner as the actual earthquake monitoring process except for displaying the training earthquake waveform data.

As described above, in the above-described embodiment, it is possible to monitor in real time vibrations such as ground vibrations due to any cause, ground fluctuations due to crustal movements, and sea surface fluctuations due to tidal tides. However, since the actual earthquake waveform is still displayed, the earthquake monitoring training can be performed without interrupting the actual earthquake monitoring process.

Although three terminal devices are provided in the above embodiment, one terminal device may display the actual seismic waveform and the training seismic waveform at the same time.

〔The invention's effect〕

As described above, according to the present invention, the training seismic waveform data is created by multiplying the training seismic waveform creation parameter by multiplying the arbitrary seismic waveform extracted from the actual seismic waveform data to the training seismic waveform data. Since the corresponding training monitoring result data is created and the training seismic waveform is displayed in real time using both of the above-mentioned data, the continuous seismic monitoring process that is performed online and in real time must be interrupted at all. Instead, you can easily create a training seismic waveform that has been amplitude-converted so that the pre-selected actual seismic waveform will have an appropriate scale, and can display it in real time. The effect that it can be obtained is obtained.
