Description

TECHNICAL FIELD The present invention relates to a method and apparatus for managing underground facilities,

The present invention relates to a facility management method and apparatus, and more particularly, to a method and apparatus for managing an underground facility.

Today, in addition to expanding the infrastructure of the city, the integrated management of various underground facilities information is being promoted in order to construct an efficient spatial information system. In Korea, the underground facilities computerization project started to systematically manage the location information of underground facilities with the gas explosion accident of Seoul Hyun-dong in Seoul in 1994 and Daegu subway in 1995 and spread to the military area in 2015, .

According to the Ministry of Land, Transport and Maritime Affairs (Apr. 12, 2011), the data integration work on the underground facilities (waterworks, sewerage, electricity, communication, gas, oil, heating)

On the other hand, most of the existing underground facilities database (DB) are classified into metal pipes, non-metal pipes and cables according to the types and materials of underground facilities by using the exploration drawings and underground exploration equipment in the surface after completion of construction. There is a limit to obtaining accurate location information on facilities in an indirect way of exploring the location. If the allowable range of the sampling error is less than 3m, the permissible range of the plane (± 20cm) and the depth (± 30cm) for the metal pipe is flat (± 20cm) Of the depth of buried depth. If the buried depth is more than 3m, the permissible range is 20% of the depth of buried metal pipes and nonmetallic pipes. Therefore, .

Therefore, the Ministry of Land, Transport and Maritime Affairs recently revised the Road Law (submission and management of the completion plan of Article 21 of the Enforcement Decree of the Road Act, application for confirmation of the completion of the construction work of Article 22 and restoration of the original state) (Drawings of underground facilities) to be submitted as electronic drawings. This suggests precise position measurement by performing three-dimensional survey with the buried pipe exposed before burial location of underground buried material is lifted.

As a result, 3 - D surveys were carried out to obtain the property information DB for the underground facilities before they were returned to the site for the underground facilities. This can improve the accuracy and the accuracy of the survey data, but it is necessary for the surveyor to stay in the field according to the three dimensional survey, which leads to increase of the surveying cost.

 Therefore, there is a need for a method for effectively determining the precise location of such underground facilities and for conveying more accurate underground facilities information to the operator.

Referring to FIG. 5, the 3D image of the pipeline may include information on the pipeline located in the basement.

As described above, the QR code may be displayed as the underground facility identification information to acquire information on the underground pipe.

When providing information on the 3D image, the 3D image information 520 for each channel can also be provided. For example, when it is desired to obtain information on a specific pipeline (city gas pipeline), it is possible to request only information on the pipeline as a 3D image. Also, according to an embodiment of the present invention, pipeline overlap pipeline information 540 may also be provided.

For example, when work for a specific pipeline is to be performed, only the pipeline information on the work pipeline can be separately provided as the pipeline pipeline information 540.

It may also provide information about the work location 500 for work on a particular pipeline. For example, when a gas pipe is required, a water pipe or a gas pipe is buried in the same vertical space and is buried, the underground facility information service server does not select the vertical position where the gas pipe is located, You can select it as your work location.

That is, the underground facility information service server not only provides information on the work location, but also provides information on the dangerous work area in the field work.

The information about the recommendation work area is provided as an augmented reality image, and work can be performed on the recommended work area represented by the augmented reality image.

FIG. 6 discloses a method for setting up a danger zone and a boundary zone according to an embodiment of the present invention.

FIG. 6 illustrates a method of setting a danger zone and a boundary zone when an abnormal situation occurs in a pipeline based on feature information of the channel.

Referring to FIG. 6, when an abnormal situation occurs in the pipeline, the danger zone and the boundary zone may be set differently according to the channel characteristic information 600.

For example, if a pipeline transports gas, a hazardous area can be set by predicting the expected area of gas spouting. Hazardous areas may be established based on the nature of the gas (gas diffusion properties) and the depth of penetration of the pipeline.

As another example, if the pipeline carries contaminated water, a hazardous area may be established based on the nature of the liquid and the depth of the pipeline.

The boundary zone (640) and the hazard zone (660) may be adaptively changed according to the time when the abnormal situation occurs. As the jetted time becomes relatively longer, the boundary zone 640 and the danger zone 660 can be relatively increased.

A control point 680 for solving the abnormal situation of the pipeline can be set based on the pipeline configuration information 620. [ For example, a control point 680 may be set for replacing the conduit based on the connection of the conduit. At this time, a control point 680 to be excavated can be determined first among the first control point or the second control point by guessing an area where an abnormal situation occurs in the pipeline.

For example, the first control point or the second control point can be determined as the control point 680 to perform the excavation first, and the excavation from the corresponding area can be determined Recommended. It is also possible to predict the location of the liquid or gas ejection and to provide information about the hazardous work area during field work for that area.

Also, according to the embodiment of the present invention, the underground facilities information service server may recommend the buried position of the pipeline based on the existing pipeline information when the new pipeline is installed.

For example, the depth of burial can be determined by taking into account the nature of the new channel, and the location of the channel can be recommended so that it does not overlap with the existing channel location.

In addition, the underground facilities information service server can analyze whether the sensor can directly affect the pipeline when performing work on the relevant area. Specifically, the sensor can sense an impact transmitted to a pipeline, and can analyze whether an impact reaching a plurality of pipelines is equal to or greater than a critical magnitude. Such a critical dimension can be determined in consideration of the depth of the pipeline buried. If the magnitude of the impact is equal to or greater than the threshold value, the pipeline is expected to be damaged. Accordingly, the operator can transmit an instruction to prohibit further work. Or whether the magnitude of the impact is increased even if the magnitude of the impact exceeds the critical size, and if the magnitude of the impact increases during the critical time, it is determined that an abnormal situation has occurred in the pipeline, It is possible to re-determine that it is not an abnormal situation.

The above-described methods may be implemented in an application or may be implemented in the form of program instructions that may be executed through various computer components and recorded on a computer-readable recording medium. The computer-readable recording medium may include program commands, data files, data structures, and the like, alone or in combination.

The program instructions recorded on the computer-readable recording medium may be those specially designed and configured for the present invention and may be those known and used by those skilled in the computer software arts.

Examples of computer-readable recording media include magnetic media such as hard disks, floppy disks and magnetic tape, optical recording media such as CD-ROMs and DVDs, magneto-optical media such as floptical disks, media, and hardware devices specifically configured to store and execute program instructions such as ROM, RAM, flash memory, and the like.
