Description
Technical field
The utility model relates to a kind of geophysical survey (abbreviation physical prospecting) surveying instrument.
Background technology
The geophysical prospecting method of measuring the alternating electric field of different frequency in the earth is called natural alternative electric field frequency-selecting geophysical measurement method (being called for short the natural electric field frequency selection method), be the new a kind of geophysical measurement method that has grown up since nearly two more than ten years, it is effective to have been facts have proved in a large number.Its surveying instrument abbreviates " natural electric field frequency selector " as.
The potential electrode device of traditional natural electric field frequency selector (abbreviation electrode) has only two electrodes that are called M, N, as shown in Figure 1.What 86201631 patents " microcomputer select frequency automatically physical prospecting admeasuring apparatus " adopted is exactly this technical scheme.The electrode mode of this technical scheme has the following disadvantages in actual measurement:
1, surveyed the data of a measuring point after, need manual traveling electrode to measure to next measuring point, tend to cause measurement data inaccurate because change, the spread of electrodes of electrode moving direction are inaccurate, measuring error appears.
2, the measurement data of obtaining is few, and measure field can only show the single-measurement curve, and can not form more intuitive two dimension or three-dimensional picture.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned prior art deficiency, and a kind of high density natural electric field frequency-selecting physical prospecting admeasuring apparatus is provided.The measurement result of this surveying instrument accurately and reliably and intuitively.
In order to achieve the above object, high density natural electric field frequency-selecting physical prospecting admeasuring apparatus provided by the utility model is improved to the multi-electrode measurement pattern with the bipolar electrode measurement pattern of traditional natural electric field frequency selector, and this instrument comprises electrode group, electrode selection circuit, selective frequency amplifier circuit and controller.
An end of each electrode insertion the earth is used to measure natural alternative electric field in the electrode group; The quantity of electrode group electrode has two at least, and the quantity of electrode does not have the restriction of the upper limit in principle, can increase and decrease its quantity according to the actual detection situation.
Electrode selects circuit to adopt general " multiselect one " analog switch, and the input end of each switch is connected with a electrode in the electrode group by cable; And the output terminal of switch and selective frequency amplifier circuit join.
During measurement, electrode selects circuit to select two electrodes and selective frequency amplifier circuit conducting under the control of controller from the electrode group; Selective frequency amplifier circuit amplifies carried out frequency-selecting by the input signal of these two electrodes of gating.
The beneficial effects of the utility model are that the electrode group can unify before measurement to arrange that the change and the spread of electrodes that electrode direction therefore can not occur are inaccurate; In measuring process, select, can obtain more measurement data by the input that changes the electrode group; Measure scene, end back and can generate two dimension or three-dimensional picture.Therefore measurement result accurately and reliably and intuitively.
