More particularly, the present invention relates to a data processing method and apparatus for determining a leakage position of a watercourse structure.

Electrical resistivity survey is one of the physical exploration methods used in various fields. Electrical resistivity survey is effective for relative detection of faults such as faults and fractures, and is one of the basic geophysical exploration methods for evaluating the stability of watershed structures such as dams. The electrical resistivity is a proportional constant, which is useful for detecting anomalies within a homogeneous object as a value representing the electrical characteristics of the object regardless of the shape and size of the object. The electrical resistivity is a proportional constant and represents the electrical characteristics of the object regardless of the shape and size of the object. They are very effective in detecting anomalies within a homogeneous object.

Conventionally, a fixing electrode as shown in Fig. 1A is used for determining an abnormal region of the water-side structure by using electrical resistivity or electric potential value. More specifically, the ten portions shown in FIG. 1A of the fixing electrode are fixed at one point on the bottom of the steel or the lake, and the potentials measured by shifting the position of the T-shaped electrode are analyzed through the equipotential line distribution. The abnormal region was judged.

However, there is an inconvenience in that the potential measurement using the conventional fixing electrode requires that the fixing electrode be directly moved to another position after measurement at one point and fixed again.

Therefore, detecting an area showing an equipotential between the upstream and the downstream and generating an equipotential line requires very precise potential value detection.

-D-Lux electric field survey method

The D-Lux electric field survey method is an electric field survey method to detect the abnormal position of a three-dimensional structure waterfront structure. Specifically, current is supplied to a line source installed by installing a line source around the waterfront structure, and a plurality of electrodes are installed in the waterfront structure in a specific arrangement. Then, it measures the potential value of the installed electrodes, the potential difference between the electrodes, the electric field, etc., and explores the abnormal position according to the measurement result.

In the D-Lux electric field probe method, the D-Lux Direct method for measuring the potential difference between adjacent potential electrodes included in an electrode line composed of a plurality of electrodes, There are several types of D-Lux electric field probing methods according to the arrangement of electrodes and the method of measuring potential difference between electrodes, such as D-Lux Parallel method for measuring the potential difference between viewing potential electrodes.

-D-Lux Tomography Electric Field Exploration Method

The D-Lux Tomography electric field probe method, which is one of the D-Lux electric field probe methods, measures the electric potential difference between the electrodes included in one electrode line and all the electrodes included in the other electrode line in two parallel electrode lines . Specifically, as shown in FIG. 1B, one of the electrodes a1, a2, ... provided at regular intervals in the upstream line source of the waterfront structure and each of the electrodes b1, b2, ... provided at regular intervals in the downstream line source of the waterfront structure, And the like.

In the embodiment of the present invention, the potential difference of each electrode is measured in the D-Lux Tomography electric field probe method, and the coordinate plane is generated by setting the horizontal and vertical axes of the plane as the electrode numbers provided on the upstream electrode line and the downstream electrode line, A D-Lux image (D-Lux Imaging View) is created by displaying the coordinate areas (cells) having the same potential difference in the same color. This makes it possible to more intuitively and precisely grasp the position of the leaking water in the waterfront structure.

FIG. 2 is a schematic view for explaining a method and an apparatus for determining a leak position of a waterfront structure according to an embodiment of the present invention.

2 (a), a leakage localization method according to an embodiment of the present invention includes one of the electrodes a1, a2, ... installed at predetermined intervals in a line source line Line1 of a waterside structure, Can be performed in the D-Lux Tomography exploration method for measuring the potential, the potential difference and the electric field with each of the electrodes (b1, b2, ...) provided at regular intervals in the downstream line source (Line2).

In the embodiment, the potential difference between the electrodes measured by the D-Lux Tomography scanning method is mapped to another color according to the measured potential difference value, and the mapped color is displayed on the two-dimensional plane shown in part (b) do. According to the embodiment, the equipotential lines can be inferred through the D-Lux imaging (D-Lux imaging) generated by representing the potential difference in color. In addition, information on an abnormal region of the waterfront structure can be more intuitively provided using the color image shown in (b) of FIG.

3 is a view showing a D-Lux image (D-Lux Imaging View) according to an embodiment of the present invention.

Referring to FIG. 3, the D-Lux image (D-Lux image) according to the embodiment has an abscissa axis set to an electrode number installed on an upstream line source Line1 of the waterside structure, And set to the electrode number provided on the line source (Line 2). When the axis is set, the coordinates of the two-dimensional plane are generated. Further, the two-dimensional plane is divided into the respective coordinate regions (cells) according to the generated coordinates. In the embodiment, since 16 electrodes are provided in the upstream line source Line 1 and the downstream line source Line 2, a total of 256 (16 × 16) coordinates and a coordinate region corresponding to the coordinates are generated. Then, the color mapped to the potential difference value between the electrodes corresponding to the respective electrode numbers of Line 1 and Line 2 is displayed in the coordinate area (cell) of the two-dimensional plane.

According to the embodiment of the present invention, by displaying the potential difference information between electrodes on a coordinate plane in color, a portion having a large potential difference can be more intuitively confirmed through color, and the position of the electrode corresponding to the coordinates of a specific color region can be grasped , It is possible to estimate the vicinity of the detected electrode as an abnormal region. This makes it possible to further improve the accuracy of grasping the water leakage position of the waterfront structure.

Hereinafter, a method of locating a water level structure leaking water according to an embodiment of the present invention will be described in detail with reference to the flowcharts.

4 is a flow chart of a method of locating a leaky water level structure according to an embodiment of the present invention.

In step S100, a potential difference between the upstream line source and the downstream line source is measured using the D-Lux Tomography method to acquire the potential difference data.

Thereafter, in step S200, color mapping is performed according to the potential difference of each of the measured electrodes. The larger the potential difference, the higher the likelihood of leakage, so it is possible to map a color that makes it more intuitive to identify areas where water leaks are likely to occur. In general, red signals tend to be recognized as dangerous signals. Therefore, for example, if the potential difference between electrodes is greater than or equal to a specific value, red is mapped. If the potential difference is less than a specific value, It can be intuitively provided through color.

In step S300, an axis is set for generating coordinates on the two-dimensional plane. For example, the horizontal axis of the two-dimensional plane may be set to an electrode number provided on the upstream line source, the vertical axis of the two-dimensional plane may be set to the electrode number provided on the downstream line source, or the horizontal and vertical axes may be set to reverse. When the axis is set by the electrode number, the two-dimensional plane is divided into the coordinate area (cell).

In step S400, a process of displaying the mapped colors according to the potential difference between the upstream line source electrode and the downstream line source electrode corresponding to the coordinates of the two-dimensional graph on the respective coordinate areas included in the two-dimensional plane is performed. The process performed in S400 will be described in more detail with reference to FIGS. 5A to 5D.

5A to 5D are diagrams illustrating an example of generating a D-Lux image (D-Lux Imaging View) according to an embodiment of the present invention.

5A is a diagram showing an ideal situation where there is no leakage in the waterfront structure. Since the potential difference between the electrode A and the electrode B, the electrode A and the electrode C, and the electrode A and the electrode D are the same, Color (blue).

5B is a view showing the shape of the equipotential line when the resistivity of the waterfront structure is low and the D-Lux image (D-Lux Imaging View).

It is possible to compare the magnitude of the potential difference between the electrodes based on the red equipotential line shown in FIG. 5B. The potential difference magnitude shown in FIG. 5B is expressed by Equation (1).

[Equation 1]

Therefore, the coordinate areas of the electrodes A and D are displayed in a blue color sequence, the coordinate areas of the electrodes A and C are displayed in green, and the coordinate areas of the electrodes A and B are displayed on the basis of the color mapping according to the voltage difference. Are displayed in a red color series.

FIG. 5C is a view showing the shape of the equipotential line when the resistivity of the left side of the waterfront structure is low and the D-Lux image (D-Lux image) accordingly. FIG. 5D is a diagram showing the shape of the equipotential line when the resistivity inside the body is low, -Lux image (D-Lux Imaging View). The D-Lux imaging view shown in FIGS. 5C and 5D is basically the same as the D-Lux imaging view shown in FIG. 5A, so that a duplicate explanation will be omitted.

FIG. 6 is a flowchart illustrating a waterline structure leakage detection process (S500) according to an embodiment of the present invention in more detail.

 In step S510, the shape of the curve that appears according to the color distribution or the color distribution displayed on the two-dimensional plane is analyzed to determine the leakage position. For example, as shown in FIG. 5D, a hyperbolic curve appears on the left and right due to the color distribution in the D-Lux image (D-Lux image) when the resistivity inside the article is low. In the embodiment, the process of collecting data based on the determination of an abnormal region of the waterfront structure is performed by extracting characteristic points (e.g., inflection point, hyperbolic point, etc.) of the curve shown in step S520. Alternatively, the distribution color of the D-Lux image (D-Lux Imaging View) is analyzed to determine the maximum potential difference and the minimum potential difference to collect data based on the abnormal region determination.

Thereafter, in step S530, the electrode position is determined through the extracted coordinate information and the data based on the abnormal region determination, and the leakage position of the water-side structure is determined based on the detected electrode position.

Hereinafter, an apparatus for detecting a leaky water level structure according to an embodiment of the present invention will be described. Since the function (function) of the waterfront structure leakage location apparatus according to the embodiment of the present invention is essentially the same as the function of the waterfront structure leakage location method, a description overlapping with those of FIG. 2 to FIG. 6 will be omitted.

FIG. 7 is a schematic block diagram of an apparatus for detecting water leakage in a waterfront structure according to an embodiment of the present invention.

 Referring to FIG. 7, the waterfront structure localization apparatus according to the embodiment may include a conversion module 100, a D-Lux image generation module 200, and an analysis module 300.

The conversion module 100 converts the potential difference data of each of the electrodes provided at predetermined intervals into the upstream line source and the downstream line source of the waterside structure measured by the D-Lux-Tomography scanning method into color data. For this, the conversion module 100 may include a potentiometer operation unit 110 and a color mapping unit 130.

The potential difference calculation unit 110 calculates the potential difference values between the electrodes by calculating each potential data obtained by the D-Lux Tomography probe method. The color mapping unit 130 maps the colors according to the obtained inter-electrode potential difference values. For example, the color mapping unit 130 may map the saturation or lightness of the same color according to a potential difference value according to a user setting, or may include a warning message if the potential difference is more than a predetermined value so as to more intuitively provide the potential difference information You can also map it to red if less than a certain value.

The D-Lux image generation module 200 displays the mapped colors according to the potential difference to generate a D-Lux image (D-Lux Imaging View). For this, the image generation module 200 may include an axis setting unit 210 and an image generation unit 230.

The axis setting unit 210 sets the horizontal axis of the two-dimensional plane to an electrode number provided in the upstream line source of the waterfront structure and the vertical axis of the two-dimensional plane graph to the electrode number of the downstream line source. The opposite is also possible. When the axis is set by the axis setting unit 210, the two-dimensional plane is divided into coordinate areas according to the number of electrodes. Then, the image generator 230 displays the colors mapped to the electrode potential differences corresponding to the respective coordinate areas included in the two-dimensional plane on the respective coordinate areas based on the information transmitted from the conversion module 100. According to the embodiment, for example, a color mapped to the potential difference value between the 7th upstream line source electrode and the 9th downstream line source electrode in the (7, 9) coordinate region is displayed in the coordinate region of (7, 9).

The analysis module 300 analyzes the color according to the electrode potential difference displayed on the image generated by the D-Lux image generation module 200 to grasp the leakage position of the water-side structure. For this, the analysis module 300 may include an equipotential line generating unit 310, an abnormal region determining unit 330, and a leakage position detecting unit 350.

The equipotential line generating unit 310 generates equipotential lines between the upstream and downstream of the waterfront structure. According to the embodiment, an equipotential line as shown in Fig. 8 can be generated. For example, the equipotential line generating unit 310 generates an equipotential line by grasping a potential value by a position of the waterfront structure based on the potential difference information of each electrode represented by hue in the generated D-Lux image (D-Lux Imaging View).

9 is a diagram showing an example of isoelectric potential generation in the embodiment of the present invention. The D-Lux image (D-Lux Imaging View) is created based on the potential difference data. Then, an equipotential line image as shown in (b), (d) and (f) of FIG. 9 can be obtained. 9 (b) is an equipotential line obtained by analyzing the D-Lux imaging image (a) of the left side of the waterside structure, and FIG. 9 (d) FIG. 9 (f) is an equipotential line obtained by analyzing the D-Lux Imaging View (c) of FIG. 9 (a) to be.

In an embodiment, the abnormal region determination unit 330 and the leaked position detection unit 350 of the analysis module 300 may analyze the shape of the generated equipotential lines to determine the leakage position of the water-side structure. For example, as shown in FIGS. 9 (b), 9 (d), and 9 (f), if the flow rate is increased due to the leakage phenomenon, the potential value changes accordingly, so that the equipotential lines become concave or convex. The abnormal region determination unit 330 and the leaked position detection unit 350 of the analysis module 300 analyze the density of the equipotential line or the region where the equipotential line is rapidly changed in the generated equipotential line image to determine the leakage position of the waterfront structure .

The abnormal region determination unit 330 analyzes the shape of the curve that appears according to the color distribution or the color distribution displayed in the generated image to calculate the range of the abnormal region including the leakage position. The abnormal region determination unit 330 analyzes a shape of a curve that appears according to a color distribution or a color distribution displayed in the D-Lux image acquired from the D-Lux image generation module 200. [ The abnormal region determining unit 330 can extract the minutiae coordinates of the analyzed curve and determine the leakage position of the water-side structure through the extracted coordinate information.

For example, as shown in FIGS. 10A and 10C, when a hyperbolic curve image appears on the left or right or up and down according to the color distribution of the D-Lux image, It is possible to determine a specific area (Area 1, Area 3) bounded by the hyperbola included as an abnormal region. The abnormal area determined on the D-Lux image (D-Lux Imaging View) can be confirmed on the image showing the equipotential line, so that the leakage position can be grasped more accurately.

Also, in the embodiment, the correlation between the two images can be grasped by comparing the ideal region determined on the D-Lux image (D-Lux Imaging View) with the image represented by the equipotential line. For example, a range (Area 1) determined as an ideal region in FIG. 10A is similar to a width (Area 2) of a concave portion in the equipotential line in FIG. 10B. The area (Area 3) determined as an abnormal region in FIG. 10 (c) is similar to the width (Area 4) of the concave portion in the equipotential line in FIG. 10 (d).

In addition, the analysis module 300 may generate an equipotential line image to identify an abnormal region of the watercourse structure. For example, the analysis module 300 generates an equipotential line of the watercourse structure by grasping the potential value by position based on the potential difference information of each electrode represented by hue in the generated image, and outputs the equipotential line form , It is possible to calculate the range of the abnormal region including the leakage position of the waterfront structure.
