Description
[technical field]
The present invention relates to geophysical exploration technology, be specifically related to a kind of fields such as oil, geology, coalfield, engineering exploration that are applied to, the wireless seismic detector system that can gather, store and transmit artificial or natural geological data.
[background technology]
Geophysical survey is to utilize seismoreceiver to obtain the seismic event information that vibroseis (or hypocenter of the explosion) produces, thereby carries out the technology that Treatment Analysis obtains ground end resource information then, and wherein, seismograph is its indispensable part.Seismograph is to utilize manual type to produce flexibly seismic wave, transmits to subsurface formations.When seismic event runs into the stratum of different wave impedance, will reflect, phenomenon such as refraction, receive, write down the data of elastic wave and be converted to high accuracy number sample streams by the surveying instrument of being installed on the ground this moment, gather the back and give analyzing and processing, thereby infer underground tectonic structure with computing machine.Seismograph must have functions such as high-precision data acquisition, time synchronized, recording storage.
At present, the data transfer mode of seismograph employing comprises wire transmission mode, wireless transmission method and data transfer mode wired, wireless mixing.
Traditional wired seismograph is that manually seismoreceiver to be given order according in advance design by the wire transmission cable in selected measured zone embedding.Vibration signal being changed into electric signal after wave detector receives seismic signal is transferred to acquisition station or central controller by transmission cable and gives layout and handle.Well imagine that heavy cable has brought the difficulty that be difficult to overcome as areas such as mountain region, marsh, rivers and lakes to investigation and prospecting at some, the area that has is had to rent the helicopter support and is produced.The wire cable mode also is subjected to the restriction of cable length simultaneously, causes measurement range to be limited to or the running program complexity.Cause so that labor intensity of operating staff is big, construction is complicated, expense is high.In addition, 3～4 years needs of every cover cable upgrade once, and expensive cable update cost and recovery cable expense make the maintenance of equipment expense increase, and impel production cost to increase significantly.Simultaneously, digital signal can be subjected in the process of wire transmission that signal between circuit disturbs and transmission course in the signal attenuation loss, thereby greatly reduce the authenticity of acquisition precision and measurement data, had influence on the final validity of wanting deal with data.
Adopt the form of acquisition station to realize in wired, the wireless seismograph that mixes mutually.Still adopt wired mode to give data acquisition between wave detector, collect the simulating signal of wave detector in suitable place by acquisition station and stored.A kind of implementation is that the acquisition station on-fixed is installed, and acquisition station can be collected the back and give taking back after wireless or wired mode uploads to the data of being handled or collecting with manual type acquisition station behind the central controller with central controller in short distance after data acquisition finishes.The real-time of this kind mode is relatively poor, if image data exists error bigger, needs the program of the sampling of earthquake once more comparatively complicated.Another kind of implementation is the acquisition station that installs and fixes repeater, receive the digital signal of seismoreceiver when repeater after, signal is transmitted to the receiving station of central controller by wireless mode.Because the installation site of repeater is fixed, so need repeater to have bigger emissive power, thereby cause repeater volume and power consumption bigger.Simultaneously, repeater does not possess the function of flexible route and optimization networking yet.Acquisition station and wave detector still adopt wired connection in the wired and wireless mode that combines of this kind, though the length of shortening transmission cable that can be suitable, this makes that the infield of acquisition station and wave detector lacks dirigibility and the overall data transmission path lacks the property optimized.
Present existing wireless seismic detector just mixes mutually with wired, wireless that the connected mode of acquisition station and wave detector changes wireless connections in the seismograph, by fixing route mode the analog signal transmission of wave detector is uploaded to the fixing route mode of central controller by wireless transmission to the acquisition station again and can not overcome the existing drawback of acquisition station.In addition, because the wireless transmission method that is adopted between wave detector and acquisition station does not possess the automatic network-building function of optimizing the path, itself and unresolved infield lack dirigibility and data transfer path lacks the difficult point of optimizing, in case the residing geographic location signal of some wave detector a little less than, can't finish the normal communication with acquisition station, then will lose the validity and the authenticity of the whole group of measurement point data influence measurement data.
