$A=\underset{i=1}{\overset{N}{\mathrm{\Σ}}}\underset{j=1}{\overset{M}{\mathrm{\Σ}}}\left|a_{\mathrm{ij}}^2\right|---\left(1\right)$

A is certain big gun gross energy, and N is the total number of channels of certain big gun, and M is number of samples together, a_ijFor i road jth The sample value of individual sampling point.

Road energy calculation formula:

$A_{\mathrm{ij}}=a_{\mathrm{ij}}^2$

A_ijFor the energy of Mou Bao the i-th road jth sampling point, a_ijFor the sample value of i road jth sampling point, a_ijLogical Cross earthquake data acquisition instrument directly to gather.

2. the algorithm of signal to noise ratio:

If Seismic Traces is x_i(t)=s_i(t)+n_i(t) (i=1,2 ..., N), total N road, wherein, s_i(t) be The useful signal in earthquake record the i-th road, n_iT () is the i-th road noise signal, x_iT () is the resultant signal in the i-th road, T is the time, x_iT () is directly obtain from earthquake-capturing instrument.The Fourier that this Seismic Traces is corresponding It is transformed to x_iF (), f is seismic channel frequency.Utilize signal correction in adjacent seismic channel and noise is incoherent Principle can draw, the average power spectra of Seismic Traces is:

$\stackrel{-}{P}x\left(f\right)=\frac{1}{2N}[{\left|x_1\left(f\right)\right|}^2+\underset{i=1}{\overset{N-1}{\mathrm{\Σ}}}{\mathrm{Px}}_{i,i+1}\left(f\right)+{\left|x_N\left(f\right)\right|}^2]---\left(2\right)$

The power spectrum of signal is: $\stackrel{-}{P}s\left(f\right)=\frac{1}{2N-1}\underset{i=1}{\overset{N-1}{\mathrm{\Σ}}}{\mathrm{Ps}}_{i,i+1}\left(f\right)---\left(3\right)$

Wherein: ${\mathrm{Ps}}_{i,i+1}=x_i\left(f\right)\stackrel{\‾}{x_{i+1}\left(f\right)}+\stackrel{\‾}{x_i\left(f\right)}{x}_{i+1}\left(f\right);$

${\mathrm{Px}}_{i,i+1}={\left|x_i\left(f\right)\right|}^2+{\left|x_{i+1}\left(f\right)\right|}^2.$

In formulaIt is the conjugation of x (f), | x_i(f) | for Fourier transform value x_iF () delivery, then noise is flat All power spectrum are:

$\stackrel{\‾}{P}n\left(f\right)=\stackrel{\‾}{P}x\left(f\right)-\stackrel{\‾}{P}s\left(f\right)---\left(4\right)$

Then the signal to noise ratio of analyzed area is:

The amplitude spectrum frequency spectrum of window Nei Gedao when calculating with fast fourier algorithm FFT, if each in analyst coverage Channel amplitude spectrum is A_i(f), (i=1,2 ..., N), total N road.It is done normalized with following formula:

In formula, A_i0F () is the amplitude spectrum after the normalization of I road,It it is I channel amplitude The maximum of spectrum.The computing formula of resolution ratio VPRS is:

$\mathrm{VPRS}=\frac{1}{m}\underset{f=1}{\overset{m}{\mathrm{\Σ}}}\left[A_{i0}^2\left(f\right)\frac{\mathrm{Ps}\left(f\right)}{\mathrm{Px}\left(f\right)}\right]$

Ps (f) and Px (f) and formula (3) synonym in formula.

4. autocorrelation analysis algorithm

Use fast fourier algorithm (FFT) process as follows:

If seismic signal to be analyzed is { x_k, its discrete auto-correlation function is:

If { x_kFrequency spectrum be { X_j, then Corr (x)_jIt is equal toInverse discrete Fu In leaf transformation, wherein asterisk represents complex conjugate.

We with following steps calculate seismic channel auto-correlation:

Calculate { x_kDFT{x_k}.

Ask $Z_k=X_k{X}_k^{*}$

Seek Z_kInverse discrete Fourier transform obtain Corr (x)_j, wherein, Z_kRepresent seismic channel frequency spectrum convolution.

5. spectral analysis algorithm

Spectrum analysis uses fast fourier algorithm (FFT).

X (e in formula^jω) it is a continuous function, it is impossible to the most on computers Do digital operation.In order to realize spectrum analysis on computers, it is necessary to the frequency spectrum of x (n) is made discrete approximation. There is limit for length's discrete signal x (n), n=0,1 ..., the DFT (DFT) of N-1 is defined as

$X\left(k\right)={\mathrm{\Σ}}_{n=0}^{N-1}x\left(n\right)w_N^{-\mathrm{nk}}---\left(5\right)$

In formula, W_N=exp(-j2π/N),n=0,1,...,N-1.Its inverse transformation is defined as

$x\left(n\right)=(1/N){\mathrm{\Σ}}_{k=0}^{N-1}X\left(k\right)*W_N^{-\mathrm{nk}}---\left(6\right)$

Wherein, N is earthquake number of channels, and X (k) is referred to as DFT coefficient, and x (n) is one geological data.

Write the definition of DFT transform as matrix form, obtained X=A*x.The wherein conversion square of DFT Battle array A is,

$A=\left(\begin{array}{cccc}1& 1& ...& 1\\ 1& W_N^1& ...& W_N^{N-1}\\ .& .& & .\\ .& .& ...& .\\ .& .& & .\\ 1& W_N^{N-1}& ...& W_N^{{(n-1)}^2}\end{array}\right)---\left(7\right)$

Dominant frequency is frequency spectrum maximum, and frequency range is 30% about dominant frequency.

6. abnormal road algorithm

The energy method of comparison that this module is closed on according to calculating, if certain energy closed on surrounding together Difference is excessive, such as more than 90%, is the most tentatively set to abnormal road, then, marks for customer analysis. By the abnormal road of monitoring, monitor the duty of wave detector further.

2) monitoring SPS data

Along with the carrying out produced, every day updates output to SPS file, is used for being supplied to data processing centre and enters Row data interpretation, is also most useful most important file in output file simultaneously.SPS file and other shakes The destination file in source, is a set of normative document, exports shot point result at focus in constructing, and comprises every The distortion of every focus, phase place in once gathering, exert oneself, the various data such as coordinate；Receive some quality and Field unit class SPS file is respectively used to wave detector pulse, resistance result analysis and finds the field lost Unit (acquisition station, power station, cross-station etc.).

3) monitoring journal file

Journal file have recorded the step that earthquake-capturing instrument is the most important.To this end, can supervise Control SPS file import, amendment, derived information, can monitor acquisition instrument gather every big gun data time Status information, including the synchronous regime of blaster state, hypocentral location and state, encoder and decoder Etc..
