Description
Technical field
The present invention relates to earthquake-capturing station, particularly relate to a kind of combined wireless and without the earthquake-capturing station of cable function.
Technical background
High accuracy number seismic detector is or earthquake signal artificial for record, then comes according to the record of these seismic signalsFind the exploration instrument for geology of oil, gas, coal and other mineral resources, and can be used for surveying earth ' s internal structure, carry out engineeringAnd geological hazards prediction etc.
Method of seismic exploration remains the Main Means at land and seafari oil and natural gas at present, is also other ore deposits simultaneouslyProduce the important exploitation method of resource, and be widely used in studying earth ' s internal structure, engineering exploration and detection, geological disaster is pre-Survey etc. aspect.
Can be divided three classes according to data transfer mode with the digital seismograph of mineral resources geophysical exploration: wire-link telemetry groundShake instrument, wireless telemetering seismic detector, without cable memory-type seismic detector.
The seismographic feature of wire-link telemetry is completely to be sent instruction and transmitted image data by wired system. Real in current fieldIn border application, occupy leading position, occupy most shares in seismic detector market, the world, conventional have a Sercel companySystemIV, the Scorpion of 408/428 series, ION company and AriesII system, German DMT companyThe UniQ system of Summit system, WestemGeco company of the U.S. etc.
The instrument that utilizes wireless system to send instruction and transmission image data is called wireless telemetering seismic detector, is generally used for distinguishinglyUnder surface condition, construct, also occupy certain market. The BOX system of Fairfield company and WirelessSeismic companyWirelessSeismic system is wireless telemetering digital seismograph. But these instruments all exist due to Wireless Data Transmission bandWide deficiency and limited the problems such as instrument road number, is used so less input is actual. Wireless telemetering seismic detector because of weightGently, lay simple and be subject to geophysical exploration expert's favor, but that its deadly defect is that wireless signal transmission can be subject to is variousThe impact of barrier (as trees, rock, mountain peak, building etc.), declines signal transfer capability, even greatlyInterrupt completely.
Be a kind of seismic detector of specific type without cable memory-type seismic detector, it is characterized in that: there is no large line, do not have earthquake number reportedlyDefeated; Each acquisition station receives blows out autostore after data, then by special data record system all data of blowing out from adoptingCollection takes out in station; There is part instrument to utilize wireless system to send and the order such as synchronously blow out acquisition station used, but do not receiveData, do not monitor the duty of acquisition station.
Summary of the invention
The object of the invention is to overcome the above-mentioned defect of prior art, provides one can be applied to various field occasion,Significantly improve instrument practicality combination wireless and without the earthquake-capturing station of cable function.
