Therefore, in order to efficiently solve the technical issues of warning information accuracy is difficult to ensure in the prior art, the present invention
Embodiment provides a kind of earthquake early-warning system based on acceleration transducer and seismologic parameter acquisition methods.
Please refer to Fig. 1, the earthquake early-warning system 1 based on acceleration transducer that first embodiment of the invention provides, comprising:
Control device 10 and multiple detection devices 20.Multiple 20 distributions of detection device are laid in seismic monitoring region.Wherein, earthquake is supervised
Survey region is Latent focal region region.It should be noted that the quantity of detection device 20 is only to illustrate in Fig. 1, this system is not limited
The particular number of middle detection device 20, the particular number of detection device 20 are arranged according to actual needs.
As shown in Figure 1, each detection device 20 includes (corresponding respectively to according to three probe units of preset interval distribution
223) and the data processing unit 210 of neighbouring three probe units setting 221 in Fig. 1,222 and.Each detection device 20

In each detection device 20, probe unit is used to obtain seismic data by acceleration transducer, and seismic data is sent
To corresponding data processing unit 210；Data processing unit 210 is for handling three corresponding with the data processing unit 210
The seismic data that probe unit is sent, obtains earthquake information, earthquake information is sent to control device 10, wherein earthquake letter
Breath includes P wave TRANSFORMATION RATIO, P wave-amplitude data, the first hypocentral location and the first earthquake magnitude size.Control device 10 is used for according to pre-
If rule chooses object detecting device from multiple detection devices 20, and is obtained based on the earthquake information that object detecting device is sent
Seismologic parameter, seismologic parameter include the second hypocentral location and the second earthquake magnitude size.It should be noted that preset rules can basis
Different early warning demand settings.For different seismic events and different early warning demands, it is chosen to be object detecting device
The number of detection device 20 can be different.
At this point, the data processing unit 210 of neighbouring three probe units setting can be quick in each detection device 20
The seismic data for handling the acquisition of these three probe units, tentatively obtains earthquake information, then obtained earthquake information is sent to
Control device 10, so there is no need to alleviate over long distances in real time to a large amount of earthquake initial data of 10 real-time Transmission of control device
Latency issue brought by data packing and network transmission is shaken, to be conducive to increase pre-warning time.And for different ground
Shake event, control device 10 can adaptively choose several object detecting devices according to preset rules, according to selected
The earthquake information that object detecting device is sent obtains relatively more accurate seismologic parameter, is generated with further according to seismologic parameter pre-
Alert information is conducive to improve the accuracy of warning information in view of pre-warning time limitation.
Further, in practical applications, often since non-seismic events lead to detection device near detection device
Wrong early warning occurs, data processing unit of the present invention can pass through the shocking waveshape of three probe units belonging to analysis thus
Correlation, to exclude non-seismic interference signal, when related coefficient be greater than threshold value when think seismic events detection effectively, be less than threshold
It is then considered external interference signal when value, the accuracy of earthquake detection can be improved in this way.
Specifically, setting the waveshape output signal of first probe unit as x1 (t), y1 (t), z1 (t), second detection is single
The waveshape output signal of member is x2 (t), y2 (t), z2 (t), and the waveshape output signal of third probe unit is x3 (t), y3
(t), z3 (t), wherein x (t), y (t) component are the output signals in two direction of trunnion axis, and z (t) component is the defeated of vertical axis
Signal out improves efficiency of algorithm to reduce the calculation amount of signal cross correlation algorithm, increases pre-warning time, selects x-axis and z-axis
Output calculate cross-correlation coefficient, formula difference it is as follows:
Wherein, γ is the global cross-correlation coefficient of normalized three probe units, and x1 (t), x2 (t), x3 (t) are respectively
The x-axis output signal of three probe units, z1 (t), z2 (t), z3 (t) are respectively the z-axis output signal of three probe units,WithRespectively its corresponding average value.
It should be noted that in order to simplify detection device 20 and obtain earthquake information as early as possible, in the present embodiment, each detection
Device 20 is provided with three probe units.Data processing unit 210 is obtained according to three collected seismic datas of probe unit
To P wave TRANSFORMATION RATIO, P wave-amplitude data, the first hypocentral location and the first earthquake magnitude size.Certainly, in other implementations of the invention
In example, three or more probe units are also can be set in each detection device 20.
Fig. 2 shows the schematic diagrames of earthquake pre-warning principle.Assuming that A indicates hypocentral location in Fig. 2, B indicates seismic wave acquisition
The position of point, C indicate the position of early warning target area, and D indicates epicentral location, s1Indicate distance of the earthquake centre to collection point, s2Indicate shake
In arrive early warning target area distance, h indicate the depth of focus.At the beginning of A when an earthquake occurs, P wave and S wave are issued around, it is assumed that P wave
Speed be vp, the speed of S wave is vs, earthquake early-warning system collects the time t of P waveABAre as follows:Assuming that from earthquake
From at the time of early warning system collects P wave, processing obtains the time of seismologic parameter as processing time tc.It should be noted that by
In electromagnetic wave propagation speed be 300,000 km/s, can to the time required for early warning target area by Electromagnetic Wave Propagation warning information
To ignore.Therefore, hedging time, i.e. pre-warning time T before the shake of early warning target area can be left for are as follows:
The time t of earthquake early-warning system acquisition P wave it can be seen from above formulaABAnd processing time tcIt is to influence in advance
The key factor of alert time.
In the prior art, the laying distance of two neighboring strong-motion instrument will be generally greater than or equal to 100km.Inventor sends out through research
Laying mode existing, that existing earthquake early-warning system can most detect seismic events fastly and trigger are as follows: earthquake is just deposited when occurring
Epicentral location, the second strong-motion instrument and third strong-motion instrument are laid in using the first strong-motion instrument as the center of circle in the first strong-motion instrument, and 100km is
On the circle of radius.At this point, choose most fast spread speed 7km/s of the P wave in the earth's crust to calculate, compared to the first strong-motion instrument, the
The time that two strong-motion instruments and third strong-motion instrument collect seismic wave at least can evening 14.29s.The ground of such first strong-motion instrument acquisition
Through long distance transmission to after being located at the warning center of distal end, warning center at least needs to wait 14.29s or more seismic wave graphic data
Time could calculate earthquake source position.That is, earthquake early-warning system collects the time t of P waveABIt is longer, while
So that processing time tcIt is longer, cause Time effect forecast poor, pre-warning time is reduced.
And in the present embodiment, since seismic monitoring regional scope is larger, in order to enable probe unit can collect ground as early as possible
Seismic wave, thus in the pre-warning time upper limit, increase pre-warning time as far as possible, in this earthquake early-warning system 1, the laying of detection device 20
Apart from relative close.For example, laying distance can be 30~50km, i.e., the distance of two neighboring detection device 20 is 30~
50km.And in the preferred embodiment, detection device 20 adds with specific reference to Seismic Intensity Zoning Map and earthquake motion peak value
Speed zoning map is laid, i.e. the high region of selection peak accelerator is laid.
In addition, earthquake information is quickly obtained in order to minimize the transmission range of the seismic data of probe unit transmission,
Three probe units of each detection device 20 are laid apart from relative close.Three probe units are advantageously reduced in this way to collect
The time of P wave, while above-mentioned processing time t can also be reducedc, to increase pre-warning time.For example, laying distance can be
1~5km, i.e., in each detection device 20, the distance of two neighboring probe unit is 1~5km.In presently preferred embodiments of the present invention
