Meanwhile, the utility model has the advantages of fast speed of data transmission, high quality signals, low error code rate, and low power consumption, and is an advanced seismic exploration data acquisition device.
Description
Technical field:
The utility model relates to a kind of seismic exploration equipment, and the signal that particularly will be distributed in the wave detector on some points in the seismic prospecting process is transferred to the equipment at record center.
Background technology:
Method of seismic exploration remains the main means at land and seafari oil and natural gas at present.Its basic skills is to bury to put thousands of and even up to ten thousand seismic event sensors (being seismoreceiver) on the ground of exploration target area, at sea then be to float cable (floating cable), use explosive (on land) or high-pressure airgun (at sea) to excite artificial earthquake then every seismoreceiver of tens of meters parcels with the long sea of the several 1-2 kilometers of sea exploration vessel drag and drop.Seismic event is propagated to deep under ground, and the interphase that runs into the heterogeneity stratum will produce reflection, and seismoreceiver picks up reflection wave and converts thereof into analog electrical signal, converts digital signal record again to and gets off.Even up to ten thousand seismoreceivers also can only cover the sub-fraction area of whole exploration target area during practice of construction, must constantly move so bury the reception plane of putting seismoreceiver, and be accompanied by blowing out one by one to spread all over whole exploration target area area.The mass data that ground observation receives also will be taken indoor high-speed computer and carries out complicated signal Processing and just can obtain clear reliable underground structure imaging, finally determines the drilling well position and the degree of depth of recover petroleum and rock gas.
Because the seismic prospecting data collecting amount is big, traditional digital seismograph mostly adopts wire transmission.A typical digital seismics instrument system is noted down 1000 road signals usually, and with the data of 24 word lengths of sampling interval 1mS acquisition, data transfer rate is up to 24Mbit/S.External existing wireless digital seismograph few in number uses FSK narrow-band frequency modulation radio station to open data channel, owing to be subjected to the narrower restriction of radio station bandwidth, the data rate of wireless transmission channel can not satisfy the seismic exploration project demand of a large amount of multichannel datas of transmission fast, so the wireless digital seismograph all adopts multichannel structure and metadata cache technology.It is an acquisition station that several channels are compiled in collaboration with, each radio station of acquisition station configuration sends data to the center, adopt FDMA and record center to get in touch between each acquisition station, Box wireless digital seismograph with U.S. FairField company is an example: the Box system adopts FDMA, and all acquisition stations transmit data in the concurrent mode of multichannel to the center; Private 1 wireless channel of each acquisition station is finished the transmission of 8 road simple component data (i.e. 8 circuit-switched data signals), and the data transmission rate of acquisition station is 192Kbit/S on year-on-year basis; It is 1 unit that per 96 acquisition stations are compiled, and takies 96 wireless channels, can transmit 768 road simple component data; It is corresponding with the wireless channel in the radio station of 96 acquisition stations respectively that 1 receiving element at system record center need be opened 96 radio station, could receive 768 road simple component data, promptly finishes the data recording of 768 tunnel seismic prospectings.Obviously exist and take shortcomings such as more frequency resource and communication facilities be huge.
Along with electronic technology and fast development of computer technology, computing machine and software processes means have reached very advanced level.For example, the effect that the spread spectrum technic of the nearest CDMA that occurs uses in the CDMA digital mobile cellular telecommunication is fine, communication spectrum utilization factor height, and the cdma system capacity with power control is 20 times of FM mode, is 4 times of TDMA mode.Radio spread spectrum communication technology makes information data to be transmitted be modulated by pseudo-random code, realizes transmitting after the spread spectrum again and receiving.This communication is different with common narrow band communication, be with behind the narrow band signal spread-spectrum, with wide band system communication, using the pseudo-random code identical with transmitting terminal to make spread spectrum demodulation earlier at receiving end handles, revert to behind the narrow band signal demodulating data again, but have anti-interference, noise resistance, anti-multipath decline, can under the low-power spectral density, work, have series of advantages such as confidentiality multiple access multiplexing and random access discrete address.In addition, the ability of the intrinsic high speed transmission data of the broadband character of spread spectrum communication itself.But this advanced person's spread spectrum does not also find application in field of seismic exploration at present.
