In the process of urbanization and improvement of quality of life, roads, water and sewage, gas and electricity, and communication facilities, which are indirect capital of society, are being rapidly developed. These facilities are essential for life and industry, and tend to be unplanned with the natural development of the community in the early stages of urbanization and industrialization.

However, these facilities such as water supply and sewage, gas, electricity, and communication are spread over a large number of spaces, and in recent years, there is a demand for a plan for the installation of these facilities, especially in urban areas that require efficient use of space. Installation is becoming common. It is also often buried underground for the purpose of protecting the facilities.

However, many existing parts of the facility were unplanned, and not all of these facilities could be planned to the end. In addition, the installation route of the facility is often changed in accordance with partial special circumstances of the region where it is installed. In addition, because the basement is not a visible space, it is often difficult to accurately identify and manage various types of buried materials buried underground. In some cases, when constructing a new facility or building a building, the existing facilities are not accurately grasped, and as the construction proceeds, the facilities are destroyed, resulting in inconvenience and economic loss of life, and personal loss may occur.

Therefore, relevant government agencies and facility management organizations are making efforts to identify and systematically manage the installation situation of existing facilities in the existing situation. Recently, the focus of attention is focused on the Geographical Information System (GIS), which is a part of efforts to realize the ubiquitous environment through the computerization of infrastructure. The GIS is mainly conducted on the research on the ground geographic information system, but recently, the ground information as well as the information on the underground buried material have been studied.

Accordingly, there is a demand for an accurate method or device for underground burial. In addition, it is often necessary to accurately identify underground burials in a specific area to prevent inconvenience or risk without damaging the existing facilities before starting a new construction, even if not in terms of overall facility management.

In general, to survey the location of underground pipes, etc., to find the location of the pipelines using detection devices, etc., and then measure the coordinates using a separate surveying device at the point. After the coordinates are measured, the measured coordinates are compared with the design drawings, and the pipeline information embedded in the corresponding position is searched, and the position information of the measured pipelines is filled in, and then used for later construction.

However, the conventional survey method as described above has the following problems.

Since the device for detecting the position of the pipeline and the device for measuring the coordinates are separate, it is inconvenient to carry both equipments, and the work step is also divided into several steps such as detection, measurement, and comparison with the design drawings. There is a slow problem.

In addition, since the device for detecting the position of the conduit and the device for measuring the coordinates are separate, it is difficult to accurately position the device for measuring the coordinates at the detected position, which makes it difficult to accurately measure the coordinates of the detection point.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of this embodiment, the same name and the same reference numerals are used for the same configuration and additional description thereof will be omitted.

First, the pipeline measurement device of one embodiment of the present invention will be described.

1 to 3 show a pipeline survey device of one embodiment of the present invention.

As shown in FIG. 1, the pipeline measuring apparatus of the present embodiment may include a pole 110, an electromagnetic field detector 120, a position measuring unit, a connecting unit 158, and a console unit 150.

When the tube buried underground is made of a conductive material, an electromagnetic field is generated when current flows through the tube. As shown in FIGS. 1 and 3, the electromagnetic field detector 120 is a component that detects an electromagnetic field generated by the tube 10, and better detects an electromagnetic field generated by the tube 10 embedded in the ground. In order to detect, the electromagnetic field detector 120 is preferably provided at the lower end of the pole 110.

In addition, the position measuring unit is a component for measuring the current position of the pipe surveying apparatus 100, and may be provided on the pole 110.

In the pipeline measurement device 100 of the present embodiment, the position measuring unit includes at least one of a satellite position signal receiver 130 capable of measuring a position through a satellite signal and an optical wave receiver 140 capable of measuring a position using a total station. Either may be provided.

Here, at least one means that either one of the satellite position signal receiver 130 and the optical wave receiver 140 may be provided or both.

The satellite position signal receiver 130 will be briefly described. Recently, a satellite navigation system has been used to accurately track the position of a specific part of the earth as a signal generated from the satellite by floating several satellites on the earth orbit. The satellite navigation system includes a GPS (Global Positioning System) operated in the US, a Galileo project operated in Europe, and a Global Navigation Satellite System (GLONASS) operated in Russia.

Satellites mounted on the Earth's orbit as described above transmits a radio wave signal containing the current position and time to the ground. The terrestrial receiver receives these signals and calculates the time it takes for the radio wave to arrive to determine its current location.

In general, three satellite signals are required to simultaneously determine longitude, latitude, and height. In addition, four satellites can be mobilized because another satellite is needed for the signal to remove the time-to-satellite error and increase the accuracy of the position measurement.

On the other hand, because the position of the satellite is measured by measuring the travel time of radio waves with the speed of light, a high precision clock is installed inside the satellite, but since these satellite signals must pass through the ionosphere and the atmosphere to reach the ground, A slight difference may occur, and an error may occur in measuring the position of the measurement point. To reduce this error, various methods are introduced. In this description, the VRS system is used as an example, and the VRS will be described later.

The optical wave receiver 140 is a device capable of measuring a distance and an angle with the total station 180 (see FIG. 4) by measuring a signal transmitted from the total station 180.

The total station 180 is installed at a reference point that already knows exact coordinates, and the optical wave receiver 140 receives a signal transmitted from the total station 180 to determine the distance and angle from the optical wave receiver 140. By measuring, the coordinates of the position where the pipe surveying apparatus 100 is located can be measured.

In the description of this embodiment, the optical wave receiver 140 may be automatically rotated to automatically measure the distance and angle with the total station 180.

The satellite position signal receiver 130 and the optical wave receiver 140 may be selectively used according to the use conditions. That is, the satellite position signal receiver 130 is limited in use in an area where the sky is invisible or bad weather, in which case the position can be measured using the total station 180 and the optical wave receiver 140. .

Of course, the position measurement using the total station 180 and the optical wave receiver 140 is also impossible to measure when there is another object between the total station 180 and the optical wave receiver 140, in this case, the satellite The position signal receiver 130 may be used to measure the position.

Therefore, since the position measurement can be performed using any one of the satellite position signal receiver 130 and the optical wave receiver 140 according to the surrounding environment, the position measurement can be performed in more various environments.

The console unit 150 may include a display unit 152 and an input unit 154 as shown in FIG. 2.

The display unit 152 is configured to display the measured or received information to the user. In addition, the input unit 154 includes a keypad and the like to receive the user's information. Alternatively, the display unit 152 may be configured as a touch screen to receive a user input.

The display unit 152 may display coordinates 152a measured by the position measuring unit, an intensity 152c of the electromagnetic field measured by the electromagnetic field detector 120, and an exploration point 152b on a map.

In addition, the display unit 152 may be configured to alarm the user when the electromagnetic field strength measured by the electromagnetic field detector 120 exceeds a predetermined value. The alarm may be made of flickering or may be made to warn the user with a beep sound.

Here, the predetermined value of the detected electromagnetic field strength for which the alarm is made may be set by the user.

In addition, as shown in FIG. 2, the console unit 150 may include a connection unit 158 to which a transceiver 210 for transmitting and receiving to and from a server provided externally is connected. The transceiver 210 may be a mobile device connected to a server using a PDA or a mobile communication terminal and a wireless Internet network. In addition, the connection unit 158 may be a kind of port that is connected to the transceiver wired 230 or wirelessly.

In addition, the transceiver 210 may be connected to the server to transmit the coordinates measured by the position measuring unit, or receive a correction value for the position from the server, the electromagnetic field detection unit 120 or position measurement It can be made to send the pipeline information measured by the department to the server or to receive the design drawings and information about the pipeline from the server.

In addition, the console unit 150 may further include a memory coupling unit 156 to which the memory unit 220 may be detachably coupled. The memory unit 220 may be a type of memory device that is freely removable such as a USB memory, an SD card, or an external hard disk and does not lose data even without a power source.

In addition, the memory unit 220 may store a schematic diagram of a corresponding local pipeline, and also store information measured as the location measuring unit and the electromagnetic field detector 120 or received through the transceiver 210. have.

Hereinafter, one embodiment of a pipeline measurement method using the pipeline measurement device will be described.

The pipeline measuring method using the pipeline measuring device according to the present embodiment has a current applying step (S100), a detecting step (S200), a coordinate measuring step (S300), and a serial numbering step (S400) as shown in FIGS. And a search step (S500).

The current application step (S100) is a step of generating an electromagnetic field in the conduit by applying a current to the conduit 10 of the conductive material using a separate current applying device 300.

In addition, the detecting step (S200) is a step of detecting the electromagnetic field generated in the conduit as the electromagnetic field detector 120 of the pipeline surveying device 100. As shown in FIG. 3, the intensity of the electromagnetic field is the largest in the vicinity of the centerline of the conduit 10, so that the path and the position of the conduit can be grasped if the electromagnetic field moves while searching for the point where the electromagnetic field is the largest.

In addition, the serial numbering step (S400) is a step of assigning a serial number for each predetermined interval on the pipeline path measured by the electromagnetic field detector 120. That is, it is a step of assigning serial numbers to R0001, R0002 .., etc. at predetermined intervals along the path of the pipeline detected by the electromagnetic field detection unit 120.

The coordinate measuring step S300 is a step of measuring the position coordinates of the point to which the serial number is assigned. In describing the present coordinate measurement step (S300), the satellite positioning signal receiver 130 and the optical wave receiver 140 are both provided in the above-described pipe surveying apparatus.

As shown in FIG. 7, the coordinate measuring step may include a determining step S310, a measuring step S322, a transmitting step S330, a receiving step S340, and a calculating step S350.

The determination step S310 is a step of determining whether position coordinates using a VRS (Virtual Reference Station) can be measured. If it is possible to measure the position coordinates using the VRS according to the determination result in the determination step (S310), the position coordinates are measured using the VRS and the satellite signal receiver (S322), and the position coordinates using the VRS are not possible. In this case, a measurement step S324 of measuring the position coordinates using the total station 180 and the optical wave receiver 140 may be performed.

Here, the VRS will be briefly described with reference to FIGS. 4 and 7.

As described above, errors can occur due to various causes until the position signal of the satellite reaches the receiver on the ground. The VRS uses the constant observation station 510 to reduce this error.

The station 510 is distributed in several places throughout the country, is installed at a precisely measured reference position and receives the satellite position signal from the satellite for 24 hours and transmits the received result to the second server 500. The second server 500 is a position measurement server that calculates a correction value by comparing the position measurement result received from the station 510 and the reference position of the station 510.

In addition, the pipeline measurement device 100 transmits the coordinates measured by the satellite position signal receiver 130 to the second server 500 through the transceiver 210 connected to the console unit 150 by wire or wirelessly. (S330)

Then, the second server 500 calculates a correction value corresponding to the point at which the pipeline surveying device 100 is located based on the coordinates received from the pipeline surveying device 100 and the calculated correction value, and then again. Transmission to the pipeline surveying device (100).

After receiving the correction value from the second server 500 through the transceiver 210 (S340), the pipe surveying apparatus 100 calculates a more precise current position coordinate as the measured coordinates and the received correction value. (S350)

And, according to the pipeline measuring method using the pipe surveying device of the present form, the search step (S500) is a pipeline corresponding to the information and design diagram of the pipeline measured in the detection step (S200) and coordinate measurement step (S300). Searching by comparing the information.

In the search step (S500), the information of the conduit corresponding to the blueprint may be stored in the memory unit 220 coupled to the memory coupling unit 156, by comparing the measured information and the stored information The user may determine and select the information by searching the information of the pipeline or simultaneously displaying the measured information and the stored information on the display unit 152.

In addition, the search step (S500) is a transmission step (S510) for transmitting the measured information to the first server, as shown in Figure 6, and the information received from the first server 300 and stored on the schematic It may also be a comparison step (S520) for comparing the information. That is, the measured information such as the position coordinates is transmitted to the first server 300, and the information measured by the first server 300 is compared with the information on the design drawing. In addition, the receiving step of transmitting the information of the corresponding pipeline retrieved by the first server 300 to the transceiver 210 of the pipeline surveying device 100, and receives by the pipeline surveying device 100 may be further included.

If the reception step (S340) is further included as described above, it is possible to receive the data searched and compared in the first server 300 without comparing itself in the pipeline surveying device 100.

In addition, after the search step S500, the display step S600 for displaying the retrieved or measured information on the display unit 152 may be performed as shown in FIG. 8.

Hereinafter, one embodiment of a pipeline survey system using the pipeline survey device will be described with reference to FIGS. 1 and 4.
