Description

Underground buried management system and information processing method

The present invention relates to an underground buried material management system and a method of processing the information for positioning and managing underground buried material using a global navigation satellite system (GNSS) and a three-dimensional model. During construction, GNSS is used to measure construction location data and wirelessly transmit the measured location data to generate a three-dimensional model through an algorithm in the three-dimensional model unit, and manage the underground buried material through the generated three-dimensional model. It relates to a buried material management system and its information processing method.

As society is advanced and complicated, installation of water supply and sewage pipes, electric power and communication lines, city gas pipelines, oil pipelines, and branch pipes accompanying house construction is increasing rapidly.These facilities are protected from aesthetics and freezing. In order to do this, most of them are buried underground. As a result, underground underground installations installed in the basement are complicatedly installed in the underground space, so it is necessary to perform maintenance through accurate information on the installation location and layout. However, since the information on the location and depth of the underground buried material is not well prepared, it is difficult to grasp the location or shape of the underground buried material, and many difficulties arise in the maintenance of the underground buried material. When constructing a building, time and cost are increased to accurately identify the location of the existing underground works, and when it is not known correctly, the existing underground works are destroyed during construction or workers are at risk. Examples of such damages include Daegu city gas explosion, communication loss due to equipment under construction, and power disconnection, and huge property and human losses are expected when underground buried property is not properly managed.

Due to the above problems, the conventional methods of detecting the embedded position, depth, direction, etc. of underground buried materials have been mainly used, such as electric sensing, electronic sensing, exploration using surface transmission radar, position detection using magnetic marker, and the like.

The electrical sensing method is to install an electrode at a point to be measured and to detect underground buried material by a difference in specific resistance measured by flowing a current through the electrode. The electronic sensing method propagates an electromagnetic wave to a point to be measured and applies it to the underground buried material. The magnetic field by the eddy current induced by the eddy current is measured, and the detection method using the surface-transmitting radar is a kind of the electronic detection method, and is mainly used for the attachment detection of underground water meters using electromagnetic waves in the high frequency band of 10 MHz to several GHz.

In addition, the position detection method using the magnetic marker is to embed a certain permanent magnet in the underground buried ground at the time of maintenance or new installation of underground buried material, and then, by using the difference in the shape of the magnetic field according to the shape of the specific permanent magnet, How to find the buried position.

However, the conventional sensing method of the above-described electrical sensing method, electronic sensing method, surface permeation radar sensing method and magnetic sensing method has the following problems.

The electrical and electronic methods are required to install electrodes and magnetic coils on the ground, so it takes a lot of time when exploring a large area, and asphalt or cement paved to install the electrodes in areas paved with asphalt or cement. Since it takes a long time and wastes a lot of manpower has occurred.

In addition, the exploration method using the surface-transmitting radar is suitable for the exploration of a few meters of deep because it uses electromagnetic waves of high frequency band, but the deep exploration of more than 10m underground is difficult, and when there are facilities or devices that emit electromagnetic waves around the exploration area, there is disturbance. Or noise (noise) greatly affects the measurement results, so precise detection is impossible, and the location or depth of the underground buried material is analyzed by the hyperbola due to the diffraction phenomenon formed when the electromagnetic waves meet the underground buried material. Accurate judgment is difficult, and the location and depth were judged by experience, and the result was incorrect.

In addition, the exploration method using the magnetic marker must use a magnetic detection device that can recognize the magnetic field shape of the embedded permanent magnet when the location of the underground buried after the specific permanent magnet embedded with the underground buried is installed, the magnetic The detector is an expensive product and difficult to carry around, which may make the user feel uncomfortable.When there is an object that forms a strong magnetic field, such as a metallic object or other underground high voltage cable, on the ground or underground, When the magnetic marker is attached, a problem that it is difficult to accurately detect at the intersection of the plurality of conduits. In addition, it is difficult to grasp the depth and position of the tube at a specific position where the magnetic marker is not attached, resulting in a problem of low efficiency.
