Description
Technical field:
The utility model relates to a kind of geophysical prospecting equipment, especially a kind of high-density electric instrument receiving magnetoelectricity signal.
Background technology:
Electrical measuring instrument, is widely used in water detection, looks for ore deposit, the aspect such as Electromagnetic Survey of Underground Pipelines and engineering quality detection, at theoretical method, method and technology all defines the system of comparative maturity.Resistivity prospecting mainly contains DC electrical method, AC electrical method and electromagnetic method three parts.Be under the jurisdiction of time domain respectively, frequency field and alternating electromagnetism method.Create again many different surveying instruments in each resistivity prospecting branch, adopt different measuring methods for different exploration objects respectively.Nearly decades, emerging high-density electric instrument development was particularly rapid, and relative research is all being weeded out the old and bring forth the new.High density electric survey originates from Britain and the Japan of the seventies and eighties in last century, a kind of new geoelectrical work method that the method mainly combines at present program control technology in computer technology and disk storage technology and derives on the basis of DC electrical method, belongs to a branch of DC electrical method.The working method that it compares the artificial race pole in Traditional DC electrical method and manually completes measurement has had very much progress, and it changes the pattern of traditional substep cloth pole manual measurement into disposable cloth pole, and disposablely under program control completes surveying work.Comparing traditional resistivity method, be characterized in arranging larger site density, automatically realizing multiple electrode spread and parameter measurement, is that current collection depth measurement and useful resistivity send out the combination method of exploration with many devices integrally, multipole distance.Observed result can be expressed as the form of two-dimensional cross-section figure, accurately can reflect the change of geoelectric cross section along survey line and the degree of depth.Because the method completes whole measuring process under program, electrode die opening urine makes final plan geoelectric cross section figure resolution high in addition.Because reflection geological information is abundant, directly perceived, datum processing is simple, Be very effective in the detection of electrically uneven geologic body.And as efficient exploration means easily, the numerous areas such as high-density electric detects at engineering geological investigation, Hydraulic and Hydro-Power Engineering, metal and a point mineral metal products, tectonic structure, archaeology and disaster geology obtain wide application, achieve good geological effect and economic results in society.But its weak point has also obviously been felt at our application practice in recent years.
CN102520449B discloses one " enhanced electrode conversion device ", any random coded waveform can be gathered, triple channel 24 three-channel simulating signals of high-speed a/d synchronous change-over circuit synchronous acquisition, once the acquisition channel measuring AB electrodes voltage was added, improve the dirigibility that any random coded waveform launched by transmitter, improve the precision of Data Analysis Services, set up the interface of ABMN electrode acquisition channel, can arrange flexibly, combine various electrical method acquisition method and deepen the investigation depth in the finite space.But under the geographical conditions of Special complex, electrode MN cannot be placed in underground, directly cause electrode cannot normal power supply, cause high-density electric instrument normally to work.
CN103837898A discloses one " high-density electric near-end dipole method for electromagnetically measuring " and makes high-density electric to carry out great deep exploration, compensate for the deficiency of electromagnetic method in shallow exploration precision; The extremely program control continuous reception of one substandard cloth, without the need to manually running pole; Based on pseudo random signal or white Gaussian noise, mixing reshaping signal is emissive source, in addition mixing coded excitation, drastically increases the diversity of multi-electrode resistivity imaging survey and the adaptability to place.The patent proposes a kind of electromagnetic exploration method of high-density electric, but just set forth specific implementation method, measurement means and the mode in magnetic field is not described.
In May, 2008 Jilin University's Master's thesis " magnetometer design based on mistor " proposes the magnetometer design scheme based on anisotropy magnetosensitive resistance, three-dimensional measurement can be carried out to magnetic field, there is the features such as composition is simple, compact, cost are lower, safe and reliable.But this design proposal is just simple measures three-component magnetic field, and seldom considers concrete practical application, also has no the bibliographical information that three-component magnetic field is applied at high-density electric.
In June, 2010 Jilin University's Master's thesis " development of large degree of depth three-dimensional high-density resistivity sending/receiving device and experiment " although reduce the receiving system of high-density electric instrument noise, reduce volume, save power consumption, increase investigation depth, but in engineering geology work progress, there is the more difficult situation maybe can not squeezing into electrode, as on hard road, the exposed rocky zone on earth's surface, still can not give full play to its effect.
The measuring accuracy of high-density electric instrument novel at present obtains large increase, be mainly reflected in the raising of A/D precision, and have employed the power supply technique that stepping powers, fraction highly dense large line is adopted to make theoretic highly dense large line can " endless ", but the large line of distributed high density is power consuming device, even if add additional supply between large line, its length is also limited.Utilize and on main frame, add the mode that the way of extension set and different frequency power make highly dense electrical method carry out in good time three-dimensional measurement.Bipolar electrode invention makes direct current high-density electric cannot carry out induced-polarization measurement or is history.Having introduced frequency measurement mode makes high-density electric can obtain the such as parameter such as complex resistivity and percent frequency effect.
Although above-specified high density electrical survey system is fairly perfect, but highly dense resistivity prospecting is the work that a practicality is very strong, its basic demand is the ability and the ability that can note abnormalities in much degree of depth and the degree of reliability that note abnormalities, and detection accuracy that is dark near the length increasing large line and raising instrument is not well positioned to meet above-mentioned basic demand.
