Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a marker for detecting underground co-

The present invention relates to a marker for detection of underground coordinates, and more particularly, to a marker for detecting the coordinates of underground objects by more precisely adjusting the angles of the underground objects such as electric power, communication, waterworks, oil pipes and gas pipes The present invention relates to a marker for detecting a coordinate of a subterranean buried object.

Various methods have been implemented to detect the buried coordinates of underground objects such as electric, telecommunication, water, gas, oil pipes, etc., but various problems have been caused due to errors in detection of coordinates of underground objects .

Hereinafter, problems related to detection errors of coordinates of underground objects such as electricity, water, gas, communication, and oil pipes, and the related art related thereto will be described in detail.

First, one of the problems of coordinate errors of underground objects is; There is a problem that the underground objects are destroyed or damaged at the time of excavation work such as the lack of connection between the ground indicator for displaying the coordinates of the underground objects on the ground and the misalignment between the various facilities and the coordinates of the underground objects . (The above-mentioned ground indicator is known from Korean Patent Laid-Open Publication No. 10-2005-0122079.)

The problem of such a ground indicator is that the design cotton for the underground has not been shared or the location has not been provided precisely.

In order to solve the above problem, it is necessary to attach an embedding information magnetic marker or an RFID (Radio Frequency Identification) tag to a subterranean buried object and to identify the type and characteristics of a pipe or pipe buried in the ground using a detector (or a detector, (Hereinafter collectively referred to as "coordinates") are identified and Big Data is provided to systematically manage the management of underground objects.

Accordingly, it is possible to reduce damage or destruction of underground objects due to excavation work, and is useful for management and maintenance of underground objects, which is a drawing of underground objects providing more accurate coordinates.

Hereinafter, conventional technologies related to underground burial detection apparatuses and the like will be described.

Reference 1 discloses a method for recording, designating and searching an existing underground buried object or a new buried object by using GPS data, and Reference 2 discloses a method for transmitting a power line communication transmission using a non-contact type power line coupler An apparatus for detecting an underground cable line by transmitting / receiving a communication signal to / from a device is disclosed.

Reference 3 discloses an underground facility information providing system using RFID that receives RFID signals from an RFID tag including a unique identification ID for underground facilities and provides information on underground facilities, And a navigation map is displayed in the guide terminal together with the location and attribute information of the underground pipe installation facility.

Reference 5 discloses a method for detecting an underground cable including a signal cable for signal transmission and an auxiliary cable in which a check conductive line is covered inside a concentric neutral cable used for a transmission / distribution cable, 6 discloses an underground buried pipe detection system for accurately and stereoscopically grasping the position and state of a buried underground pipe such as a gas pipe, a power / communication pipe, and the like.

However, the detection structure of the underground buried object may fail to recognize the correct information if the magnetic marker or RFID tag providing the underground information is not correctly installed, thus losing reliability of the equipment.

For example, an accident that breaks a power line during the installation of an H beam for the installation of a subway elevator, etc. occurs frequently due to the substantial burial position of the track and the location detected by the detector, This indicates the importance of accurate detection of line coordinates.

Accordingly, various techniques for more accurately detecting the coordinates of underground objects have been developed.

Reference 7 discloses a system in which an RFID tag can be attached to an underground object to detect underground objects. Reference 8 discloses a system in which a magnetic marker is attached to an underground object to detect the underground object using the magnetic field of the magnetic marker System is disclosed.

Reference 9 discloses an apparatus for acquiring the underground channel position information by displaying the position of the underground channel in three dimensions in accordance with the reference quantity data obtained by accurately obtaining the two-dimensional coordinate data of the underground channel while traveling through the underground channel , And Reference Document 10 discloses an apparatus for providing a location identifier, which is a combination of an RFID antenna and a magnetic body, on the upper side of a subterranean underground and providing accurate recognition and location information of underground facilities through the location identifier.

In Reference Documents 11 and 12, a system is disclosed in which a magnetic marker / magnetic marker is attached to a subterranean underground, and the magnetic marker / magnetic marker is detected and the amount of the spot is detected to construct a DB and to manage underground facilities in connection with GIS. Reference 13 discloses a system in which a magnetic body used for amplifying a change in a magnetic field of the earth is attached to a pipe when attached to a cylindrical pipe, thereby managing the underground buried object.

Reference Document 14 discloses a device that includes an RFID chip and a GPS chip in a tubular body buried in the ground and installs a pipeline information module protruding from the body toward the ground so that the accurate burial position of the body buried in the ground can be grasped Lt; / RTI >

As a method for detecting the coordinates of the underground objects as described above, there is a method of detecting the information of the buried object using the magnetic field of the magnet and setting the RFID marker (RFIR tag) with the RFID chip installed A system for receiving and reading information according to the frequency band of radio waves, and the like, are known.

However, the two methods using the magnetic markers and the RFIR markers have a problem in that the magnetic markers are wound around the uppermost surface of the underground material such as a pipe line by winding the magnetic markers with tape or the like, And the position of the attached marker tends to fluctuate.

If the embedding information markers are not vertically positioned toward the ground (i.e., they are not positioned horizontally in parallel to the ground), horizontal adjustment (angle adjustment) with the above-described positional change is not possible, and the coordinates between the coordinates recognized by the detector and the actual embedding A large error is generated, which causes a problem that is detected and recognized incorrectly.

In other words, if the magnetic marker is described as an example, the magnetic field of the magnet comes out of the N pole and forms a closed curve that goes into the S pole. If the magnetic marker is not horizontally positioned along the ground surface, The magnetic field from the detector will form a magnetic field at an oblique angle, so that the detector will detect and recognize the magnetic field at an oblique angle.

Therefore, the tilted angle makes a larger error range according to the depth (the error range according to depth becomes C> B> A> order), and the error length becomes proportional to the tilted angle and depth, The RFID marker has a greater distance from the ground due to the tilted angle and a greater influence on the reception rate of the frequency along the depth (distant distance), so the detector does not correctly recognize the frequency of the RFID marker And a situation that can not be achieved occurs.
