Both the two multi-frequency induced polarization instrument receivers are in two-way connection with the computer.
Description
Technical field
The present invention relates to suppress in a kind of electrical method geophysical prospecting equipment the device, particularly a kind of multi frequency induced polarization instrument system that suppresses phase drift and coupled noise of phase drift and coupled noise.
Background technology
At present, in the use procedure of electrical method geophysical prospecting equipment receiver, due to the variation of electric current in current supply circuit, the electromagnetic wave that is coupled to measuring circuit via the earth (or air) makes the observation signal of induced polarization measurement produce distortion, and this distortion can affect the sharp telecommunications breath of even falling into oblivion mineral matter; And, be proven, in the use of multi frequency induced polarization instrument receiver, in Land Environment, meeting produces some electricity, change effect because the signal pickup electrode of measuring junction is inserted, in signal is observed for a long time, these electricity, change effect can make phase parameter produce drift, thereby cause the erroneous judgement of underground mineral information disconnected.In more existing electrical method instruments, although taked some measures to suppress electromagnetic coupling effect, all can not obtain good effect, even can lose a part and swash the telecommunications breath; And, yet there is no a kind of effective solution for the inhibition problem of phase drift.
Summary of the invention
Technical matters to be solved by this invention is, not enough for prior art, a kind of multi frequency induced polarization instrument system that suppresses phase drift and coupled noise is provided, do not losing under the prerequisite that swashs the telecommunications breath, suppress well electromagnetic coupling effect, and solve in the situation that long-term observation, phase place produces the problem of drift.
for solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of multi frequency induced polarization instrument system that suppresses phase drift and coupled noise, comprise computing machine, two multi frequency induced polarization instrument receivers and a multi frequency induced polarization instrument transmitter, two transmitting terminals of described multi frequency induced polarization instrument transmitter and two receiving ends of the second multi frequency induced polarization instrument receiver respectively are connected to a ground-electrode that inserts the earth, be connected to a sample resistance between transmitting terminal of described multi frequency induced polarization instrument transmitter and coupled ground-electrode, two receiving ends of the first multi frequency induced polarization instrument receiver are the described sample resistance of access in parallel two ends respectively, described two multi frequency induced polarization instrument receivers all are connected with described computer bidirectional.
Compared with prior art, the beneficial effect that the present invention has is: the present invention can suppress electromagnetic coupling effect well not losing under the prerequisite that swashs the telecommunications breath, and solves in the situation that long-term observation, and phase place produces the problem of drift.
Description of drawings
Fig. 1 is one embodiment of the invention structural representation.
Embodiment
As shown in Figure 1, one embodiment of the invention comprises PC, two multi frequency induced polarization instrument receivers and a multi frequency induced polarization instrument transmitter, two transmitting terminals of described multi frequency induced polarization instrument transmitter and two receiving ends of multi frequency induced polarization instrument receiver 2 respectively are connected to a ground-electrode that inserts the earth, be connected to a sample resistance between transmitting terminal of described multi frequency induced polarization instrument transmitter and coupled ground-electrode, two receiving ends of multi frequency induced polarization instrument receiver 1 are the described sample resistance of access in parallel two ends respectively; Described two multi frequency induced polarization instrument receivers all are connected with described PC is two-way.
The ground-electrode of setting multi frequency induced polarization instrument transmitter transmitting terminal is A, B, and the ground-electrode of two receivers (receiver 1 and receiver 2) receiving end is M, N.Because electromagnetic coupling effect is that in current supply circuit, the variation of electric current causes, during construction, powerful sample resistance of the A utmost point (the perhaps B utmost point) series connection before the direct current that multi frequency induced polarization instrument transmitter transmitting terminal sends feeds the earth, the two ends of sample resistance are accessed respectively between the M utmost point and the N utmost point of receiver 1, and made receiver 1 normal operation; Simultaneously, at receiving end, two ground-electrodes are inserted the earth, and the two ends of electrode are accessed the M utmost point and the N utmost point of receiver 2 with wire, and make receiver 2 normal operations.Like this, receiver 1 has been preserved the measurement parameter that comprises coupled noise and phase drift, and receiver 2 has been preserved and comprised coupled noise, phase drift, and the measurement parameter of sharp telecommunications breath.After construction is completed, with the measurement parameter importing PC of receiver 1 and receiver 2 preservations, and concern that by the time the sharp telecommunications that correspondence is subtracted each other after namely being inhibited ceases parameter.
