HIGH PRECISION AUGMENTED REALITY APPARATUS OF UNDERGROUND UTILITIES INFORMATION FOR EXPLORING A COMPOSITE PIPE USING RESISTIVITY, AND THE METHOD THEREOF}

The present invention relates to a device and a method for providing a high precision augmented reality of the underground buried information for exploring the composite pipeline using the electrical resistivity, and more particularly to the underground buried through the electrical resistivity distribution obtained by the potential difference for each location of the ground The present invention relates to a technology for acquiring pipeline information related to the augmented reality mode.

Due to inaccurate landfills of water, sewage, electricity, telecommunications, gas, oil, and heating pipelines, which are buried underground for city aesthetics and safety, communication failures are the main cause of pipeline damage when constructing buildings, subways, roads, etc. It causes secondary damage such as water shortage, power failure and gas leakage.

In the past, technologies such as magnetic markers, electromagnetic induction exploration, surface penetration radar, magnetic field communication, and electrical resistivity have been widely used for the exploration of seven underground underground facilities that have been complicated, but without the prior information of pipelines buried in a specific area It was impossible to obtain the whole information through the buried pipe.

Further, in order to carry out excavation work, it is necessary to survey existing spatial information data to grasp information of underground pipelines (or underground burial). However, in the past, the local government, the National Geographic Information Institute, and Korea Electric Power Co., Ltd. requested pipeline information of the relevant region and synthesized it into a three-dimensional CAD (Computer Aided Design) to analyze the pipeline information comprehensively. Equipment and service development was required.

Tunnel and underground buried exploration using electrical resistivity is based on the principle that when two probe rods are installed in different locations and voltage is applied to one probe rod, the current flowing from the probe rod is the same as the current flowing into the other probe rod. Based.

That is, the current density distribution in the state in which only soil constituting the general ground is present and the current density in the case where other materials, for example, an electric power pipe, a water pipe, a sewer pipe, and a heating pipe are included, are different from each other. By analyzing the current and resistance relations for two different combinations of probe rods, they are applied to the exploration method by extracting n different equations in order to obtain n variables.

Therefore, by using this method, it is possible to obtain the central position (x, y, z) of the pipeline embedded in the basement, the radius (r) of the pipeline, the material of the pipeline (m), the direction of the pipeline (d).

However, a large amount of calculation is required to calculate the simultaneous equation, and the calculation amount and the accuracy vary greatly depending on which pattern the plurality of probe rods are installed in.

Tunnel and underground buried exploration using existing electrical resistivity selects the general installation structure that installs two probe rods at intervals of 2 meters at intervals of 10 meters, but is reasonably reasonable in the absence of prior information of underground pipelines. In most cases, this square installation can be achieved with a combination of seven basic underground works (communication pipes, power pipes, water pipes, sewer pipes, heating pipes, gas pipes, oil pipes, etc.). It is almost impossible to explore pipeline information.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited or limited by the embodiments. Also, like reference numerals in the drawings denote like elements.

Also, the terminology used herein is a term used to properly express a preferred embodiment of the present invention, which may vary depending on a viewer, an operator's intention, or customs in the field to which the present invention belongs. Therefore, the definitions of the terms should be made based on the contents throughout the specification.

1 is a block diagram illustrating a detailed configuration of a device for providing a high precision augmented reality of underground information embedded in the underground to explore a complex pipeline using an electrical resistivity according to an embodiment of the present invention.

Referring to FIG. 1, an apparatus for providing a high precision augmented reality of underground buried information for exploring a composite pipe using an electrical resistivity according to an exemplary embodiment of the present invention may be provided in an underground buried material through an electrical resistivity distribution obtained by a potential difference for each location of the ground. Obtain relevant pipeline information and provide it in augmented reality mode.

To this end, the high-precision augmented reality providing apparatus 100 for underground buried information for exploring the composite pipe using the electrical resistivity according to an embodiment of the present invention is the measuring unit 110, the management unit 120, the pipe determination unit 130 ), The pipeline information acquisition unit 140 and the information providing unit 150.

The measuring unit 110 injects current into the plurality of probe rods installed on the ground, calculates the potential difference for each position of the ground, measures the distribution of the electrical resistivity of the ground, and measures the position information of the buried underground buried material.

For example, the measuring unit 110 generates a voltage signal according to a frequency and converts the current into a current, selectively injects a current into at least one selected pair of probe rods among a plurality of probe rods installed in an area to be probed, and not selects a probe rod. By measuring the induced voltage with respect to the current injected through the electrical resistivity distribution by the potential difference of the voltage can be measured.

More specifically, the electrical resistivity distribution obtained from a plurality of probe rods may include the center coordinates of the underground deposits, the radius of the underground deposits, the electrical conductivity of the underground deposits, the electrical lowness of the surrounding medium, the dielectric constant ratio, the radius of the probe rods, and the probe rods. It may be formed as a function of distance and number of probe rods. Among these, in case of performing field or indoor experiments, previously known variables may be the radius of the probe rod, the distance between the probe rods, the number of probe rods, and the electrical resistivity distribution value.

For this reason, the measurement unit 110 based on the electrical resistivity distribution, using the reverse analysis algorithm, the electrical conductivity of the underground buried, the electrical conductivity of the surrounding medium, the dielectric constant ratio, the center coordinate of the underground buried, the radius of the underground buried and the underground buried At least one or more of directions of may be predicted.

At this time, the measuring unit 110 may repeat the process of obtaining the electrical resistivity distribution from the plurality of probe rods by selecting different pairs from the plurality of probe rods.

Since the measuring unit 110 has eight variables to obtain, that is, the electrical conductivity of the underground buried material, the electrical conductivity of the surrounding medium, the dielectric constant ratio, the center coordinate of the underground buried material, the radius of the underground buried material, and the direction of the underground buried material, at least 8. Electrical resistivity distribution can be obtained.

The apparatus 100 for providing high precision augmented reality of underground buried information for exploring a complex pipeline using an electrical resistivity according to an embodiment of the present invention may include an inverse analysis algorithm (eg, a genetic algorithm, Monte Carlo) on the obtained electrical resistivity distribution. By obtaining a variable to predict by applying the method, etc., it is possible to obtain the location, size, direction and relative weakness of the underground buried. According to an embodiment, the process of obtaining the position, size, direction, and relative weakness of the underground deposit by applying the inverse analysis algorithm to the electrical resistivity distribution is performed by the measuring unit 110 according to the embodiment of the present invention. It may be, but may be performed by the pipeline information acquisition unit 140.

The probe rod must be grounded to the ground and can be connected wirelessly between points. Further, the arrangement and spacing of the probe rods may be set according to the exploration resolution (precision) and the terrain conditions. For example, probe rods can be used in a Wener array, Schlumberger array, Pole-Pole array, Pole-Dipole array, or Dipole-Dipole array. It may be installed by at least one arrangement method, and the distance and the number may be different according to the arrangement method and the terrain conditions.

According to an embodiment, the measurement unit 110 may measure the distribution of electrical resistivity of the buried underground buried material by using vertical or horizontal survey, or simultaneously using vertical and horizontal surveys.

The vertical exploration is a concept corresponding to horizontal electric exploration and is an exploration method for acquiring water component guns from the basement to the core while increasing the interval of the probe rod at a specific position. In addition, the horizontal exploration is an exploration method for investigating horizontal changes in the underground structure. The horizontal exploration is performed along a predetermined side line and can be detected while maintaining the arrangement interval and the transmission / reception interval of the probe rods in electric and electronic exploration.

The measuring unit 110 analyzes the positioning data of the underground underground material from the electrical resistivity distribution, and uses the positioning data and the external coordinate data received from the external high-precision positioning module 10 to determine the absolute coordinates of the buried underground buried material. Can be converted.

At this time, the high-precision positioning module 10 may be a positioning receiver that improves positioning accuracy by minimizing a distance from a mobile station (ROVER) by interlocking its own base station and continuously using correction information.

For example, the user may move the area to be explored using the high precision positioning module 10, and external positioning data on the buried underground buried material obtained by the high precision positioning module 10 may be a virtual reference station (VRS) system. Can be sent to. Accordingly, the measurement unit 110 of the apparatus 100 for providing high precision augmented reality of underground information for exploring the complex pipeline using the electrical resistivity according to an embodiment of the present invention is an area to be explored from a VRS (Virtual Reference Station) system. May receive location data for.

In addition, the measurement unit 110 receives the external positioning data from the VRS system or the high precision positioning module 10 moving the exploration target area, and obtains the high-precision position information for the underground buried material using the external positioning data and the positioning data. can do.

At this time, the measurement unit 110 may obtain high-precision position information for the underground buried material by continuous correction of data according to the movement of the user adjusting the external high-precision positioning module 10. The location information of the high precision may include at least one or more of the pipeline size of the underground buried, pipeline connection information, pipeline direction, pipeline location and depth of the pipeline.

The water supply pipe is buried at a depth of 1m to a depth of 50m underground, so it is difficult to detect the buried position of the water supply pipes buried in the ground by the existing detection technology, but the composite pipe is used by using the electrical resistivity according to the embodiment of the present invention. The exploration depth of the high precision augmented reality providing device 100 of the underground buried information for exploration is possible to 12m, up to 20m is suitable for exploration.

The manager 120 learns the measurement result information including the electrical resistivity distribution and the position information in the database DB 160.

The database 160 may store and maintain at least one or more information of pipeline type, pipeline material, pipeline size, pipeline connection information, pipeline direction, pipeline location, and depth of pipeline embedded in underground burial by area and location. have. In addition, the database 160 measures the measurement result information measured by the measuring unit 110 of the apparatus 100 for providing high precision augmented reality of underground information for exploring the composite pipe using the electrical resistivity according to an embodiment of the present invention. In addition, at least one or more of a pipe type, a pipe material, a pipe size, a pipe connection information, a pipe direction, a pipe location, and a buried depth of the pipe may be learned.

Underground soil structures and pipeline information have many cases, which can be learned based on numbers obtained through experience. Experience can be obtained through actual surveys of various ground structures and landfill pipelines through actual measurements, but as more of these actual data accumulate, the database 160 for learning is sufficient, enabling machine learning for more accurate exploration. .

For example, when the medium property of a water pipe, which is a cast iron pipe, is 1, the medium property of a sewage pipe, which is a concrete pipe, is 2, and the medium property of a power pipe, which is a PVC pipe, is 4, the medium information between any two points is 5. If obtained, it is possible to infer that a water pipe and a power pipe pass between these two points. Of course, even if one water pipe and two sewer pipes are obtained as 5, it can be assumed that it is extremely rare that two sewer pipes simultaneously pass. In this case, by narrowing two points from the analogy that two pipes flow, a single pipe can be traced by trial and error until the medium information is 1 or 4 is obtained. That is, according to the present invention, when the measurement value is known, the pipeline information embedded in the basement can be predicted by tracing back the components constituting the measurement value.

The apparatus 100 for providing high precision augmented reality of underground buried information for exploring complex pipelines using electrical resistivity according to an embodiment of the present invention performs the above-described trial and error in an automated manner, thereby obtaining a more accurate probability of obtaining pipeline information. Can be improved.

Thus, it is possible to determine a complex pipeline or a single pipeline of underground burial according to the measurement result information in the exploration target area.

The pipeline determining unit 130 may determine a single conduit including a single conduit or a complex conduit including different buried conduit information on a plurality of underground burials embedded in an exploration target area.

The pipeline information acquisition unit 140 acquires pipeline information related to the underground buried material according to the result determined by the pipeline determination unit 130.

The pipeline information acquisition unit 140 may obtain the position, size, direction, and relative weakness of the underground buried material by applying an inverse analysis algorithm to the electrical resistivity distribution measured by the measurement unit 110. In addition, the pipeline information acquisition unit 140 may infer the electrical resistivity distribution, and may infer the position and direction of the underground buried material on the ground surface by applying the resistance value and the reverse analysis technique measured indoors or in the field.

The method of FIG. 6 is performed by the apparatus for providing high precision augmented reality of underground buried information for exploring a composite pipe using an electrical resistivity according to an embodiment of the present invention shown in FIG. 1.

Referring to FIG. 6, in operation 610, current is injected into a plurality of probe rods installed in the ground, the potential difference for each position of the ground is calculated, the electrical resistivity distribution of the ground is measured, and the position information of the buried underground buried material is measured. .

Step 610 may be a step of selectively injecting a current in at least one selected probe rod of the plurality of probe rods, measuring the voltage through the non-selected probe rod, and measuring the electrical resistivity distribution by the potential difference according to the measured voltage .

Step 610 generates a voltage signal according to the frequency and converts it into a current, selectively injects current into at least one selected pair of probe rods of the plurality of probe rods installed in the area to be probed, and applies a current to the current injected through the unselected probe rods. The electrical resistivity distribution may be measured by measuring the induced voltage, and the electrical resistivity distribution due to the potential difference of the voltages may be measured.

More specifically, the electrical resistivity distribution obtained from a plurality of probe rods may include a center coordinate of underground burial, a radius of underground burial, electrical conductivity of underground burial, electrical lowness of surrounding medium, permittivity ratio, radius of probe rod, and probe rods. It may be formed as a function of distance and number of probe rods. Among these, in case of performing field or indoor experiments, previously known variables may be the radius of the probe rod, the distance between the probe rods, the number of probe rods, and the electrical resistivity distribution value.

For example, step 610 obtains an electrical resistivity distribution from a plurality of probe rods installed that are larger than the range of roughly expected underground deposits. In this case, step 610 may repeat the process of obtaining the electrical resistivity distribution from the plurality of probe rods by selecting different pairs from the plurality of probe rods.

Thereafter, in step 610, at least eight electrical resistivities are obtained because eight variables are acquired: electrical conductivity of underground embedding, electrical conductivity of surrounding medium, permittivity ratio, central coordinate of underground embedding, radius of underground laying, and direction of underground laying. It may be a step of obtaining a distribution.

In addition, step 610 interprets the positioning data for the underground buried ground from the electrical resistivity distribution, converts the absolute coordinates of the buried underground buried using the positioning data and the external positioning data received from the external high-precision positioning module, It may be a step of obtaining the high-precision position information for the underground buried material by the continuous correction of the data according to the user's movement to adjust the external high-precision positioning module.

At this time, the high-precision positioning module may be a positioning receiver that minimizes the distance to the mobile station (ROVER) by interlocking its own base station to improve positioning accuracy and continuously utilize correction information.

In operation 620, the measurement result information including the electrical resistivity distribution and the position information is learned in the database DB.

In operation 630, the measurement result information is analyzed based on the database to determine a complex pipeline or a single pipeline of underground burial.

Step 630 uses machine learning based on artificial intelligence (AI) based on a database or deep learning (Deep Learning) to provide information about measurement results in an area to be explored. It may be a step of determining a complex pipeline or a single pipeline according to the underground buried.

In step 640, pipeline information related to the underground burial is obtained according to the determined result of the complex pipeline or the single pipeline.

In operation 640, a reverse analysis algorithm may be applied to the electrical resistivity distribution measured in operation 610 to obtain the position, size, direction, and relative weakness of the underground deposit. In addition, step 640 may theoretically derive the electrical resistivity distribution, and may infer the location and direction of the underground buried material on the ground surface by applying the resistance value and the reverse analysis technique measured indoors or in the field.

As a result, step 640 may be performed in the area to be explored, the pipe type, pipeline material, pipeline size, pipeline connection information, pipeline direction, pipeline location and embedding depth of the pipeline, either a single pipeline or a single pipeline for underground burial of the measurement target. It may be a step of obtaining pipeline information including at least one of the above.
