Fig. 2 is the structure composition schematic diagram of the device of secondary of the present invention location wave detector.
Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the invention will be further described, can not be used for limiting the scope of the invention.
See Fig. 1, the present invention proposes the method for a kind of secondary location wave detector, preserve the geocoding of transponder in advance, the method comprises:
SPS (Shell processing support format for land 3d surveys) file in step 100, payout process in the auxiliary navigational system of extract real-time, becomes ASLAID file by the SPS file transform of extraction.
In this step, SPS file is the industry standard that petroleum prospecting association specifies, is the standard format of field seismic acquisition data recording geometry data record.Effect is, the shot point of the field acquisition of shooting crew and geophone station position data and relevant geophysics auxiliary data, to be sent to processing enter, namely can to shorten the cycle, can greatly reduce error rate again with a kind of general standard format.
In this step, auxiliary navigational system refers to the system be made up of the navigational system of each ship of subsea cable fleet.Auxiliary navigational system can be MVRS, is carried out the transmitting-receiving of data, signal between the navigational system of each ship by many communi-cation system.MVRS is combinationally used by the radio station of 2.4GHz and 11Mb bandwidth spread spectrum and the Free Wave radio station of 900MHz.Exchanges data is carried out by switch and auxiliary navigational system in 2.4GHz radio station, and the navigational system main frame of several ships is formed a LAN (Local Area Network), and communication is directly carried out with auxiliary navigational system by netting twine in 900MHz radio station.
In this step, microwave telecommunication system can be adopted to extract SPS file in auxiliary navigational system, and specific implementation belongs to the common practise of those skilled in the art, repeats no more here.
In this step, ASLAID file is become to comprise the SPS file transform of extraction:
Front 32 row retaining SPS file are constant; From the 33rd row, the S4027 in first row is changed to R4027, the 1R1 in secondary series is changed to 1HG, retain the third line constant to the 8th row.
Step 101, the ASLAID file importing pre-configured asset file in principle navigation system and be converted to; The position that secondary location obtains acoustics transponder is carried out to acoustics transponder.
In this step, asset file comprises serial number, acoustics transponder address number, acoustics transponder frequency number, acoustics transponder response time and is in the pile No. of wave detector of same position with acoustics transponder.
In this step, at principle navigation system co-ordinate Database nodec window selection ASLAID, in option, select to import, under respective path, select the file be converted to, select line in preplot before, paint name, line name is filled in ASLAID option, in vessel, select corresponding cable laying name of vessel, finally click import, ASLAID file is imported.
At existing principle navigation system co-ordinate Database nodec window selection ASSETS, select the ASLAID file imported, in option, select to import, under respective path, select ASSETS file, click import, import file.
