Description

[0001] The present invention relates to a mobile underground facility monitoring system using smart markers,

The present invention relates to a system to which a mobile underground facility monitoring method using smart markers is applied in the field of geodetic surveying technology, more specifically to a system including information of underground facilities and information of ground indicators and underground facilities installed on the ground, By monitoring the underground facilities' base information, location information, terrain information and property information by using smart markers, RFID tags, Wi-Fi devices, etc., a number of underground indicators embedded in the underground facilities together with the facilities, And a system to which a mobile underground facility monitoring method using a smart marker capable of preventing a large accident occurring during construction due to unknown location information of underground facilities is applied.

Natural disasters such as gas pipe explosion, city gas explosion, pipeline rupture, and stability of special underground facilities buried underground such as sewage, gas, electric power, communication, heating, Together, continuous maintenance is becoming important.

However, since the types of underground facilities are not uniform, burial conditions are not standardized, and they are buried underground in a complicated form. Therefore, not only the safety management such as confirmation and inspection is insufficient, but also, It is difficult to do so, which can lead to a great loss of human and material due to unexpected accidents.

In order to prevent accidents occurring in underground facilities, a management system that can systematically and comprehensively manage underground facilities is needed.

In order to manage the underground facilities, firstly, the survey should be done to acquire the topographical map, the cross / cross section, and the underground facility map. In particular, for the design of large accident by underground facilities and construction of other underground facilities, information related to underground facilities should be accurately represented on the topographical map.

Underground facilities to be considered in the design of underground facilities include water and sewage pipes, power distribution lines, communication lines, and city gas pipelines. The attributes of the underground facilities to be recorded on the topographic map are the material of the pipe, the length of the pipe, the diameter of the pipe, the number of pipes, the depth of the pipe, and the location of the pipe.

By constructing the GIS using the precise location and information of the underground facilities, it is possible to prevent large accidents when constructing underground facilities and to identify the scope and location of accidents in case of accidents, have.

Underground facilities for underground facility management are also provided with numerical mapping and underground facility management system. Waterworks management, sewage management, pipe network analysis, water / sewage diagram management and output, water / sewage facility statistics, distance and area measurement function / buffer zone zone, and area), and so on.

In addition, it is impossible to know whether or not the design drawings of the underground facilities are in agreement with the actual construction locations and specifications. Therefore, it is not possible to confirm until the location is directly parsed.

There is a great demand for a system that can easily input and confirm such information, but it does not support it so far. In addition, if the system that can manage this information is combined with information such as GPS, accuracy and scalability of the information can be greatly increased. Therefore, a comprehensive management system is required for underground facilities such as gas pipelines, gas pipelines, and oil pipelines have.

In order to meet this need, Korean Patent Registration No. 10-1122185 (Feb. 23, 2012) "Underground Facility Management System Using Information Recognition Means and Method" has been disclosed as an improved prior art.

However, the above-mentioned registered patent according to the prior art uses a magnetic marker as a means necessary for providing information, and it is difficult to confirm the attribute information including the type of pipe, depth of burial, and, incidentally, various methods such as QR mark are utilized, Since the amount of information is limited because processing is required, there is a need for improvement.

In addition, existing magnetic markers are largely affected by external environments such as spawning and electronic devices, are not semi-permanent, are sensitive to changes, are difficult to maintain, and can not be edited in real time.

In addition, since the existing magnetic markers are simple buried type, they are liable to be damaged by the earth pressure, and are liable to be lost due to poor stability.

However, the present invention is characterized in that the additional embodiment portion which improves a specific constituent part in order to achieve the object of the constitution disclosed in the above-mentioned Japanese Patent No. 1122185 is the most essential constitutional feature.

Therefore, the device configuration, characteristics, and operation relationship described below will be described with reference to the main features of the present invention while partially citing the contents of the above-mentioned Japanese Patent No. 1122185.

As shown in FIG. 1, the system according to the present invention is installed on a plurality of points where there is almost no place movement, and the base information, the location information, and the information of the underground facility 200 embedded in the vicinity A plurality of ground indicators 10-1, 10-2, ..., 10-n including; A plurality of underground facilities 200 including information of underground facilities 200 included in the plurality of ground indicators 10-1, 10-2, ..., 10-n, Indicators 20-1, 20-2, ..., 20-n; And acquires information from the plurality of ground indicators 10-1, 10-2, ..., 10-n and the plurality of underground indicators 20-1, 20-2, ..., 20- A user terminal 30 for acquiring location information of a location where a plurality of ground indicators and underground indicators are installed, location information, and location information of an underground facility 200 buried nearby; A communication network (40) for providing communication between the user terminal (30) and the location information server (50); 10-2, ..., 10-n and the underground indicators 20-1, 20-2, ..., 20-n in the user terminal 30 through the communication network 40, ..., 10-n) and the underground indicators (20-1, 20-2, ..., 20-n) and a location information server 50 for decrypting the information included in the user information and transmitting the information to the user terminal 30.

At this time, the unrecorded reference numeral 60 is a server of the national geographic information source, and provides the geographical information of the area requested by the location information server 50.

2, the location information server 50 is connected to the control center through an intranet or the Internet as a concept of a WAS server, communicates information necessary for the control, and receives a web-based GIS service .

The geographical information server 60 corresponds to the related institutions 1, 2, ..., n in FIG. 2, and functions to confirm and provide necessary map information and coordinate information to enable processing of the GIS service of the WAS server do.

In particular, the control center is configured to be capable of real-time monitoring of information through bidirectional communication, and the user terminal 30 means a mobile field system.

In this case, the mobile can be various forms such as a smart phone, a PDA, and a tablet PC.

Others The business DB server and the like shown in FIG. 2 are means supplementarily included for storing, updating, or processing information.

In addition, the landmark 10-1, 10-2, ... 10-n included in the mobile field system includes a marker detector 310 (see Figure 3) and a reader 320 (see Figure 3) and a Wi-Fi device , And the underground indicators 20-1, 20-2, ... 20-n are preferably smart markers 300 (see FIG. 3).

Here, the smart marker 300 has a unique identification number (ID), and is a type of indicator used to divide the frequency according to the type of underground buried object and to detect burial depth.

Such a smart marker 300 can modify, edit, and manage the type, depth, ID, and attribute information of the tube, and provides the frequency for each marker. Therefore, the smart marker 300 is not affected by the external environment, It is semi-permanent, light and hard, easy to maintain, and has real-time drawing editing capability.

Such a smart marker 300 may have a ring shape or a ball shape, as shown in the example of FIG.

Thus, when the underground facilities 200 are buried, the smart markers 300 are attached and embedded at predetermined intervals.

At this time, the position value (x, y, z) of the smart marker 300, that is, the three-dimensional coordinate value, is measured when the smart marker 300 is embedded.

In this case, the three-dimensional coordinate value can be checked by using the user terminal 30, the communication network 40, the position information server 50, or the like.

When the position value of the smart marker 300 is confirmed, the ID information of the smart marker 300 is used as a basic key to input the measurement data and other attribute information related to the underground facility 200 through the user terminal 30.

Then, the ID value is stored and managed through the location information server 50 in a state including various kinds of information.

At this time, the information may include drawing information.

Thereafter, when the underground facility 200 is maintained or excavated, the smart marker 300 is detected through the reader 320 using the detector 310.

The detector 310 detects the presence or absence of the smart marker 300 and when the smart marker 300 is detected, the reader 320 reads the ID value of the detected smart marker 300 and transmits the ID value of the smart marker 300 to the user terminal 30 through the Wi- Lt; / RTI >

The user terminal 30 accesses the location information server 50 through the communication network 40 to inquire information on the underground facility 200 on the screen of the user terminal 30 and edit the information if necessary.

Meanwhile, as shown in FIG. 4 in addition to the above-described configuration, the system according to the present invention further includes a smart marker protector 400.

The smart marker protector 400 is added to enhance the durability of the smart marker 300 embedded in the underground facility 200 to achieve longevity and to eliminate the risk of losing the smart marker 300.

The smart marker protector 400 includes a base plate 410 on a disk.

A plurality of fastening holes 412 are formed at intervals in the circumferential direction of the base plate 410.

The fastening hole 412 is a means for fastening and fixing the underground facility 200 using a bolt nut when the underground facility 200 is not a pipe, that is, a tubular body.

However, since most of the underground facilities 200 are typically tubular bodies such as water pipes, sewage pipes, and conduits, the main structure is that they can be attached to them.

In addition, a cylindrical coupling end 414 having a hollow inside is protruded from the lower center of the base plate 410, and a thread is formed on the inner peripheral surface.

A plurality of exhaust holes 416 are formed in the coupling end 414 at intervals in the circumferential direction.

An outer cylinder 418 is integrally formed on the upper surface of the base plate 410 and a smart marker 300 is installed in the outer cylinder 418.

In this case, the illustrated example is merely an example that the smart marker 300 is a ring-shaped one, and it is also applicable to a case where the smart marker 300 is a spherical one.

In addition, a cushion pad 422 is seated on the upper surface of the smart marker 300, and the cushion pad 422 has a donut shape.

Therefore, the smart markers 300 do not interfere with communication at all.

In addition, the open top of the outer cylinder 418 is configured such that the cover 420 is hooked and sealed.

Accordingly, the buffer pad 422 is closed and fixed in the outer cylinder 418 in a state of being trapped by the cover 420.

On the other hand, the coupling end 424 is screwed to the coupling end 414.

At this time, an exhaust passage 426 having a predetermined radius is formed in the coupling end 424, and a check valve 428 is fixed on the exhaust passage 426.

The check valve 428 is a known valve which is opened only to the side of discharging air and is hermetically closed on the side of suction.

A suction plate 430 is integrally formed at the lower end of the coupling end 424 so as to be hemispherical. The suction plate 430 has a hollow portion 432 to fill the inside of the suction plate 430, It is preferable to be made of a urethane resin having excellent adhesiveness.

Here, the attracting plate 430 may be provided with a plurality of holes having different radii. However, the engaging tabs 424 should be formed identically and be removably attached to the engaging tabs 414.

In addition, a rubber magnet 434 is integrally fixed to the bottom surface of the adsorption plate 430.

Thus, when the underground facility 200 is a tubular, non-magnetic PVC pipe, it presses the attracting plate 430 with a strong force.

Since the air inside the hollow portion 432 is exhausted through the exhaust passage 428 and the exhausted air is discharged to the outside through the exhaust hole 416 through the check valve 428, Thereby firmly adhering to the outer circumferential surface of the underground facility 200.

Particularly, since the attracting plate 430 has high adhesiveness, it is not easily pushed, moved or dropped.

Since the attracting plate 430 has various shapes according to the size of the tube of the underground facility 200, it is possible to assemble the same suitably.

If the tube is made of a metal material adsorbed by magnetic force, the attraction force is further increased by the rubber magnet 434.

Then, when the coupling end 414 is fastened to the fastening end 424, it is possible to stably fix the smart marker 300 while preventing the leakage of the smart marker 300.

Particularly, since the cover 420 and the buffer pad 422 prevent the smart marker 300 from being damaged from the earth pressure at the time of embedding, the life span of the smart marker 300 is also improved.
