Description
Technical field
The present invention is to be related to a kind of damping device, concretely relate to one kind can generate waveform go offset earthquake marble
The seismic shock wave of waveform is alarmed and damping device.
Background technique
Earthquake becomes because of the characteristics of its is sudden and destructive and endangers one of major natural disasters of human life.About
Research in terms of seismic monitoring emerges one after another, and people are also higher and higher to the required precision of seismic monitoring.Currently, prediction earthquake side
There are many method, through data show as earth magnetic field survey shake method, electric field, gravitational field, crustal stress, tilt survey shake method, level of ground water become
Change and method is shaken in the surveys such as chemical composition change and various animals and plants abnormal responses.But existing various forecast instruments will receive from
Piling when influencing such as explosion, construction of various factors, coal mining accident, train shake, and when warning instrument or equipment produce
When raw larger reaction, earthquake source reaches close in earth's surface, and forecast at this moment is perhaps meaningless, and if generated
The reaction of very little will cause the suspicion of wrong report again, and the purpose of early warning is almost not achieved.And above method is technically still continuous
It explores, the defects of that there are sensitivity is not high for facility, poor reliability, anti-interference ability is weak, can not be competent at demanding to accuracy rate
Shake task is surveyed, causes to predict an earthquake as world-famous puzzle.
However the method that a variety of pairs of seismic signals are handled, earthquake are had existed in seismic signal analysis field at present
Signal is the combined harmonic being superimposed by different-energy, seismic wavelet of different shapes.Wherein multiple wavelet decomposition and reconstruction skill
Art can decompose signal, and a series of collection of wavelet sequences is resolved into according to the characteristics of attributes such as its frequency, amplitude, energy
It closes, then obtained wavelet is rebuild according to certain rule, these wavelets have different dominant frequency, different wavelet breadths and not
Same time location.By these wavelets be superimposed can the original seismic signal of Exact recovery to be used for seismic signal analysis.
The research of multiple wavelet decomposition and reconstruction technology has important practical significance and application value.Match tracing technical application in recent years
Into seismic data processing, a seismic wave is resolved into a series of wavelets, these wavelets are referred to as in wavelet Time-frequency Decomposition
Time-frequency unit.During match tracing, in order to reasonably characterize continuous wavelet, need using following five parameters: amplitude A,
Time shift u, scale (time shaft length) σ, average frequency ω and phase.Conventional matching pursuit algorithm is one pretty troublesome
Iterative process needs to select the wavelet of suitable parameters from a large amount of small echo dictionaries abundant.Then it is excited by manual method
Seismic wave, ground generate vibration signal and propagate in the earth formation, which can generate arbitrary waveform generator, generate
Achieve the purpose that damping with the waveform of seismic wave wavelet waveforms opposite in phase for offsetting the part wavelet of seismic wave.It will be this
Seismic shock wave damping device is placed in the underground of residential quarter, when shear wave and standing wave pass to fast ground when an earthquake occurs, because
To seismic wave wave cancellation, so that the fluctuation for being transmitted to ground reduces, this allows for the reduction of the earthquake magnitude above device, makes the rolling in house
It is dynamic to weaken, the further injures and deaths for reducing personnel.
Summary of the invention
Object of the present invention is to overcome deficiency in the prior art, a kind of novel seismic processing mode is provided, is jumped out
The bottleneck of earthquake monitoring system research and development, inventing a kind of instrument can be realized earthquake wave decomposition, and provide alarm in the short time.
To which the earthquake magnitude of seismic wave be effectively reduced.People's injures and deaths are avoided the occurrence of, ensure the security of the lives and property of people.
In order to solve the above-mentioned technical problem, the present invention is achieved through the following technical solutions:
1, it monitoring device group: is made of electromagnetic wave measurement instrument 1, seismic detector 2, signal receiver 3, electromagnetic wave measurement instrument 1 and earthquake
Instrument 2 monitors earthquake conditions, and signal is transmitted to signal receiver 3 in real time.
2, it warning device group: is made of signal processor 4, power amplifier 5, buzzer 6, signal processor 4 is to signal
Receiver 3 is transmitted through the signal come and is handled, and amplifies through power amplifier 5, buzzer 6 is connected to signal and alarms.
3, damping device group: being made of shear wave standing wave drainage device 7, match tracing device 8, electromagnetic wave attenuation device 9, horizontal
Wave standing wave drainage device 7 drains seismic wave, and electromagnetic wave attenuation device 9 is generated by match tracing device 8 and seismic wave
The waveform of wavelet waveforms opposite in phase, to offset seismic wave.
Compared with prior art, the beneficial effects of the present invention are:
Present apparatus collection seismic monitoring, alarm, damping, can effectively weaken influence of the earthquake to the mankind, reduce house because
For the manufacturing cost of antidetonation, can also reduce by piling when being influenced from various factors such as explosion, construction, thing on coal mine
Therefore train shakes.More effectively avoid earthquake bring disaster.
