Description
Technical field
The present invention relates to ocean bottom seismic data acquisition technique field, and in particular to the data acquisition of IMF-OBS a kind of is extracted
Method.
Background technology
IMF-OBS is interactive multiband ocean bottom seismic data reception device, what earthquake or man-made explosion were produced
Seismic wave can be got off, data sink is adopted by the reflection on seabed and stratum by geological data reception device acquisition and recording
The data of collection directly by existing main flow seismic processing software can handle and then extract the geological data of collection again；For
Realize data acquisition and the abstraction function of above-mentioned geological data reception device, it is necessary to design a set of and interactive multiband seabed
The data acquisition extracting method of geological data reception device matching.
The content of the invention
In view of the shortcomings of the prior art, the present invention is intended to provide a kind of matching is interactive multiband suitable for IMF-OBS
Ocean bottom seismic data reception device gathers and extracted the IMF-OBS of ocean bottom seismic data data acquisition extracting method.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of data acquisition extracting method of IMF-OBS, including data acquisition, file header are obtained and data extract three steps；
Wherein, data acquisition flow is：1st, the gathered data function of selection IMF-OBS collectors is started；The 2nd, the data of collector are set
Acquisition parameter, such as delay duration, collection duration；3rd, send and start acquisition to collector, gathered data is started by sending
Wrap and realized to collector；4th, collector receives acquisition, starts gathered data；5th, acquisition state is sent to application by collector
System, and acquisition state is shown in daily record print zone by application system, complete gatherer process；
File header obtains flow：1st, application system takes file header button to send acquisition file header command code to collection by clicking on
Device；2nd, application system receives the File header information Date bag that collector is replied；3rd, system judges the number of File header information Date bag
According to validity, whether File header information Date bag is four-way；4th, the data of File header information Date bag effectively then extract head text
Part full detail；5th, the data invalid of File header information Date bag does not extract detection gain, detection sample rate then；6th, to file header
The header file full detail extracted when the data of information packet are effective is preserved and shows extraction data, completes file header
Acquisition；
Data extract flow：1st, command code is extracted by taking data button to send data to collector, and opens timer；2、
Receive the gathered data bag that collector is replied；3rd, the validity of data is judged；5th, data effectively then preserve data to once delivering
Name Documents are pressed from both sides, Off Timer after data are preserved successfully；6th, after the completion of all data are preserved, point out data to extract and terminate and close
Close timer；If the 7, data invalid, number of times is automatically extracted by what timer was set, then number is extracted by Timer Controlling
According to extraction is extracted again automatically when failing, and then points out to extract data failure when extracting failure 3 times and Off Timer terminates to carry
Take；8th, progress is extracted by system interface display data and current data extracts byte number.
The present invention has the advantages that：
A kind of IMF-OBS data acquisition extracting method of the present invention, can be matched suitable for the i.e. interactive multiband seabeds of IMF-OBS
Geological data reception device gathers and extracted ocean bottom seismic data.
Brief description of the drawings
Fig. 1 is a kind of data acquisition flow figure of IMF-OBS of the invention data acquisition extracting method；
Fig. 2 obtains flow chart for a kind of file header of IMF-OBS of the invention data acquisition extracting method；
Fig. 3 extracts flow chart for a kind of data of IMF-OBS of the invention data acquisition extracting method.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the invention will be further described, in order to be more clearly understood that this
The claimed technological thought of invention.
A kind of IMF-OBS of the invention data acquisition extracting method as Figure 1-3, including data acquisition, file header are obtained
Take and extract three steps with data；Wherein, data acquisition flow is：1st, the gathered data work(of selection IMF-OBS collectors is started
Energy；The 2nd, the data acquisition parameters of collector, such as delay duration, collection duration are set；3rd, send and start acquisition to collector,
Realized by sending startup gathered data bag to collector；4th, collector receives acquisition, starts gathered data；5th, collector
Acquisition state is sent to application system, and acquisition state is shown in daily record print zone by application system, gatherer process is completed；
File header obtains flow：1st, application system takes file header button to send acquisition file header command code to collection by clicking on
Device；2nd, application system receives the File header information Date bag that collector is replied；3rd, system judges the number of File header information Date bag
According to validity, whether File header information Date bag is four-way；4th, the data of File header information Date bag effectively then extract head text
Part full detail；5th, the data invalid of File header information Date bag does not extract detection gain, detection sample rate then；6th, to file header
The header file full detail extracted when the data of information packet are effective is preserved and shows extraction data, completes file header
Acquisition；
Data extract flow：1st, command code is extracted by taking data button to send data to collector, and opens timer；2、
Receive the gathered data bag that collector is replied；3rd, the validity of data is judged；5th, data effectively then preserve data to once delivering
Name Documents are pressed from both sides, Off Timer after data are preserved successfully；6th, after the completion of all data are preserved, point out data to extract and terminate and close
Close timer；If the 7, data invalid, number of times is automatically extracted by what timer was set, then number is extracted by Timer Controlling
