Description

 The invention is intended to search and determine the location on the earth's surface of zones caused by anomalies in the distribution of aquifers and layers with different chemical compositions, and adversely affecting the health, well-being and behavior of humans and animals, which can lead to pathological conditions and diseases, and can be used in various sectors of the economy, in particular - in medicine and agriculture.

 There are various methods for determining soil properties, described, for example, in USSR author's certificates N 298915, MKI G 01 V 3/04 on "Method of geoelectrical exploration", dated 16.03.1971 and N SU 1233078, MKI G 01 V 3/18 on "Device for measuring the magnetic susceptibility and conductivity ", from 05.23.1986.

 According to these technical solutions, an MS-08 grounding meter is used, with the help of which the resistivity of high-resistance rocks between two points of the earth's surface is determined. Or in the environment they induce a magnetic field. The result of the interaction of the magnetic field with the soil substance is judged on the magnetic susceptibility of the soil in this area.

 A common drawback of analogues is the measurement of the local conductive properties of a plot of the earth's surface, which does not allow one to find out the direction to the geopathic zone and organize its search and localization.

 Closest to the claimed technical solution is the device according to the author's certificate of the USSR N 1004938 dated 03/15/1983, MKI G 01 V 3/02 on "Method for measuring the potential difference of an electric field". The essence of this technical solution lies in the fact that at two points between which it is necessary to measure the potential difference of the electric current excited in the earth by pulses of direct current introduced through the supply electrodes, two receiving electrodes are installed. For this configuration, the location of the supply and receiving electrodes determines the position of the equipotential lines passing through the receiving electrodes. Having determined the position of two equipotential lines, they install systems of at least three receiving electrodes connected to each other through a summing operational amplifier, or through voltage followers, and measure the difference of the total potentials between these lines.

 The known solution has a number of significant drawbacks, which are as follows.

 Since the supply electrodes are placed separately from the receiving electrodes in the soil, each rule of mutual configuration requires its own rule for determining equipotential lines. Therefore, the structure of blocks implementing each new calculation algorithm should be determined and implemented again for each selected configuration of the arrangement of electrodes.

 Since there are only two receiving electrodes, it is not possible in all cases to determine the position of equipotential lines.

 To determine the position of two equipotential lines, it is necessary to conduct preliminary measurements twice, moving the position of the electrodes and the configuration of the location of the supply and receiving electrodes.

 Determining the potential difference between two equipotential lines does not always indicate the direction of the gradient of the change in soil properties.

 The main disadvantage of the described method is that it measures only the characteristics of the soil, stimulated by external pulsed exposure. At the same time, the heterogeneity of the chemical composition of the soil can generate its own internal soil currents, which are not measured by the described method, but which serve as an indication of the direction to the geopathic zone.

 In addition, the known solution does not separately measure the properties of the soil when exposed to an external electric current at different frequencies. At the same time, soils of different chemical composition react differently to currents of different frequencies, having their own frequency response, and the possible measurement modes for them may vary.

 The above disadvantages indicate that using the prototype it is difficult to conduct a reliable search for soil with anomalous properties and determine the position of geopathic zones.

 The problem solved by the invention is to increase the accuracy and convenience of searching and determining the location of geopathic zones.

 This problem is solved by the fact that in the device containing the first, second, third and fourth electrodes, a square frame is introduced with first, second, third and fourth electrodes fixed at its corners, as well as a first subtraction unit, the inputs of which are connected to the first and third electrodes , a second subtraction block, the inputs of which are connected to the second and fourth electrodes, a third subtraction block, whose inputs are connected to the outputs of the first and second subtraction blocks, a fourth subtraction block, whose inputs are connected to the outputs of the first of the second and second memory elements, and the fifth subtraction block, the inputs of which are connected to the outputs of the third and fourth memory elements, and the outputs of the fourth and fifth subtraction blocks - with the inputs of the second indication block, an adder whose inputs are connected to the outputs of the first and second subtraction blocks, and the output through the first analog-to-digital converter to one of the inputs of the first display unit, the output of the third subtraction unit through the second analog-to-digital converter is connected to another input of the first display unit, and the control input Both analog-to-digital converters are connected to one of the outputs of the control unit, its other output is connected to the sweep generator, and its third output is to the control inputs of all memory and switch elements, the other switch input is connected to one of the sweep generator outputs, the third the input is with the output of the current meter, and the first, second, third and fourth outputs of the switch are with the corresponding electrodes, the other output of the sweep generator is connected to the input of the current meter, and the other output of the current meter through the third analog-to-digital converter azovatel - to the inputs of all memory elements.

 This embodiment of the device for the search for geopathic zones allows you to quickly determine the direction to the geopathic zone using the frame, as well as process measurement information in a complex of electronic blocks for convenient presentation on the screen.

 Variants of the image created on the screen allow you to conveniently present the measurement results in various modes.

 Localization of geopathic zones using the proposed device makes it possible to highlight places that adversely affect the health and behavior of people and animals. This allows you to adjust the placement of residential buildings and other structures in order to reduce the impact of negative factors.

 The drawings show: in Fig. 1 is a structural diagram of a device for searching for geopathic zones.

 Figure 2 is a plot explaining the principle of operation of the device.

 The device consists of the first 1, second 2, third 3 and fourth 4 electrodes, square frame 5, first 6, second 7, third 8, fourth 9 and fifth 10 blocks of subtraction, first 11, second 12 and third 13 analog-to-digital converters, the first 14, second 15, third 16, fourth 17 memory elements, switch 18, sweep generator 19, current meter 20, first 21 and second 22 display units, control unit 23 and adder 24.

 The electrodes 1-4 are mounted in the corners of the square frame 5, the frame is horizontally placed in the selected area, the electrodes 1-4 are brought into contact with the soil. In blocks of subtraction 6-10, the output voltage is proportional to the difference in voltage at the inputs. In the adder 24 is proportional to the sum of the input voltages. Analog-to-digital converters 11-13 translate the continuous value of the input signal (in analog form) into the output digital code. The memory elements 14-17 memorize a digital code arriving at their inputs, and store it until a control signal arrives at their control inputs. At the time of its arrival, the new value of the input digital signal is stored and stored until the next control signal arrives.

 The switch 18 connects two of its input signals to two of its four outputs. The connection option is determined by the control signal supplied to the control input of the switch. Sweep generator 19 is a generator of sinusoidal signals with a varying (in a certain interval) frequency. Frequency tuning is triggered by an input control signal. The current meter 20 measures the current that flows from its input to the output and a signal is generated at the other output that is proportional to this flowing current. The first display unit 21 has visual display means in the form of a screen on which a mark is formed. Label deviation along two perpendicular axes is controlled by the input signals of the first 11 and second 12 analog-to-digital converters. The second display unit 22 also has a screen with a label, the deviation of which along the two perpendicular axes is controlled by the input signals of the fourth 9 and fifth 10 units of subtraction. The measurement process is divided into two stages.

 In the first stage, the direction and magnitude of the soil currents in a selected surface area are measured.

 In the second stage, measure the magnitude and direction of the conductivity gradient in the selected area at different frequencies.

 The work in the first and second stages is controlled by the control unit 23. In the first stage, the switch 18 is closed and the sweep generator 19 is disconnected from the electrodes.

 Differences in the chemical composition of the soil leads to the appearance of a potential difference at different points on the surface and soil currents. These potential differences fall on the electrodes 1-4. In the first block of subtraction 6, the potential difference between the first 1 and fourth 4 electrodes is determined and amplified, in the second block of subtraction 7, the potential difference between the second 2 and third 3 electrodes is determined and amplified. In the third block of subtraction 8, the difference is determined, and in the adder 24, the sum of the output voltages of the first 6 and second 7 blocks of the subtraction. After converting to digital form, these two digital codes fall on the first display unit 21. It has a screen that is rigidly oriented relative to frame 5. If the digital codes correspond to zero voltages at the inputs of blocks 11 and 12, the mark remains in the center of the screen. If there are currents in the soil, then the mark on the screen of block 21 is shifted from the center in the direction of flow of these currents and by a distance proportional to their value, which is the purpose of measurement at this stage.

 In the second stage, the control unit 23 turns off the analog-to-digital converters 11 and 12 and includes a switch 18. It also includes a sweep generator 19 and memory elements 14-17. The frequency of the sweep generator 19 varies smoothly or discretely in the range from low frequencies, for example, from tens of hertz, close in properties to a constant voltage, to high frequencies, for example, to hundreds of kilohertz. The rate of change of frequency is set such (for example, kilohertz per second) to have time to measure the direction and magnitude of the resistance gradient.

 Two poles of the sweep generator 19 through a current meter 20 are connected to the switch 18. In accordance with the control signal of the control current 23, the switch 18 connects the voltage of the generator 19 in series to the electrodes 1-2, to 2-4, to 1-3, to 2-4 . In each of the four states, current is measured by meter 20. Its value is converted from analog form to digital using the third analog-to-digital converter 13. Digital codes corresponding to the result of measuring the current in each of the states are stored in memory elements 14-17. The storage mode in each of the memory elements 14-17 is activated by the control signal of the control unit 23. In this case, the measurement result in each of the four states of the switch 18 is fixed in one of the four memory elements 14-17. In the fourth block of subtraction 9, there is the difference between the numbers encoded by the digital codes of blocks 14 and 15, and in the fifth block of subtraction 10, by the codes of blocks 16 and 17. The codes of blocks 9 and 10 are supplied to the second display unit 22 and control the position of the mark on its screen. The signals of blocks 9 and 10 are used to shift the mark in two perpendicular directions by an amount proportional to the conductivity of the soil and in the direction of its gradient.

 The principle of searching for geopathic zones using the proposed device is as follows. From the starting point, the search is performed by a step-by-step procedure. At each step, the device measures the direction of soil currents. If the magnitude of the soil currents is negligible, then determine the direction of the gradient of soil conductivity at different frequencies. In the direction where the gradient is most pronounced, the operator moves a certain distance to carry out the next step of the procedure. Here the whole operation is repeated, the direction for the next movement is determined, etc.

 Thus, the operator shifts towards the geopathic zone, which is an anomaly in the form of a spot or “fault line”.

The measurement process in each step is based on the following. At the first stage, the direction of soil currents is determined by the combination of potentials on the electrodes (Fig. 2). Current I, flowing through the soil with finite resistance, creates a potential difference at various points on the surface. Let the current direction I be oriented relative to the frame 5, as shown in FIG. 2 (the X and Y axes are directed along the sides of the frame). Potentials at electrodes 1-4 - U ₁ -U ₄ . Then the ratio of potential differences U ₃₁ = U ₃ -U ₁ and U ₃₄ = U ₃ -U ₄ is equal to the ratio of the projections of the current I _y and I _x on two perpendicular axes directed along the sides of the square frame 5.

To improve accuracy, the potential difference is measured twice: U ₃₁ and close to it in magnitude U ₄₂ = U ₄ -U ₂ , as well as U ₃₄ and close to it in magnitude U ₁₂ = U ₁ -U ₂ . Indicated close values add up. Thus, the ratio I _x : I _y , which determines the orientation of the current direction I relative to the frame, is determined by measuring the voltage ratio (U ₁ -U ₂ + U ₃ -U ₄ ): (U ₃ -U ₁ + U ₄ -U ₂ ), or, which is the same thing, [(U ₃ -U ₂ ) + (U ₁ -U ₄ )]: [(U ₃ -U ₂ ) - (U ₁ -U ₄ )]. The values of (U ₁ -U ₄ ) and (U ₃ -U ₂ ) are determined in blocks 6 and 7, respectively. A value proportional to I _x is generated at the output of the adder 24 and the analog-to-digital converter 11. The value conducting I _y is generated at the output of the third subtraction unit 8 and the second analog-to-digital converter 12. These values control the mark offset on the screen of the first display unit 21 along the respective axes. Since the screen is rigidly connected with the frame, the operator will know the direction of the current I in the soil relative to the frame.

The conductivity gradient is measured in the second stage. The current meter 20 sequentially measures the current between the electrodes 1 - 2, 3 - 4, 1 - 3.2 - 4, created after connecting the voltage of the sweep generator 19 to these electrodes. The output voltage of the sweep generator 19 is kept constant, therefore, the measured current is proportional to the conductivity of the soil between the respective electrodes. The measurement results are digitized in block 13 and sequentially recorded in blocks 14-17. They are values proportional to the conductivities G ₁₂ , G ₃₄ , G ₁₃ , G ₂₄ , where the indices indicate the numbers of the electrodes.

Next is the gradient by comparing the corresponding conductivities. If the Y axis is directed from electrode 3 to electrode 1, and the X axis is directed from electrode 3 to electrode 4, then the projection of the conductivity gradient on the X axis will be proportional to ΔG _x = G ₁₃ -G ₂₄ , and the projection on the Y axis ΔG _y = G ₁₂ -G ₃₄ . Thus, the digital code at the output of block 9 contains information about ΔG _y , and the code at the output of block 10 contains information about ΔG _x . These signals are supplied to the second display unit 22 and are used to offset the mark on its screen along the corresponding axes. The screen of the block 22 is also rigidly connected to the frame 5 and the direction and magnitude of the soil conductivity gradient (uniquely related to the resistance) at a given frequency can be determined by the position of the mark on it. If the conductivity is different at different frequencies, the operator observes the graph in polar coordinates and can shift the frame in the next step in the direction of the largest radius vector.

 The screens of both display units 21 and 22 can be structurally 2 combined, and the labels corresponding to the marks of currents and gradients differ in color. Color may vary for clarity and marks corresponding to measurements at different frequencies of the sweep generator 19.
