First, the Internet of Things will be briefly explained.

The Internet of Things (IoT) refers to the ability of everyday objects, other than computers and computer networks, to be readable, recognizable, localizable, addressable, and controlled via IoT communication networks (e.g., ad-hoc systems or the Internet). It is based on the idea that it is possible.

In other words, the Internet of Things (IoT) is a new information and communication basis that connects existing objects to the Internet and allows communication between humans and objects and between objects and objects anytime, anywhere.

The system according to the present invention uses the Internet of Things to check information on underground facilities, and confirms the actual buried location and shape of underground facilities through exploration equipment, so as to increase the precision through double surveying and exploration. It was done.

The system according to the present invention is intended to accurately retain location information of underground facilities (mainly oil pipes, gas pipes, water pipes, or communication pipes) by reflecting the construction status of the underground facilities on the map.

In particular, in the case of newly built underground facilities, buried information using IoT has already been displayed on the ground surface, so read it to check the information on the relevant underground facility, and check how and in what form it is buried through exploration equipment. Update this to the map information.

Also, in the case of existing underground facilities, there is no IoT information, so after confirming the buried location, burial depth, and type through exploration equipment, buried underground facility information is shared with the management company or the government agency in charge, and then processed to enable IoT. A marker is installed on the surface of the buried facility so that subsequent investigators can easily and conveniently detect it.

In this case, the present invention uses QR code for IoT utilization.

To this end, the system according to the present invention communicates with the management server 10, where underground facility information and map information is registered, as shown in Figures 1 and 2, and buried underground facility information. A QR reader (20) equipped with a display (22) that reads underground facility information from a recorded QR code sign and displays the reading information, detects the underground facility, and transmits the detected shape information to the management server (10) to determine the shape. It includes a detection unit 30 that confirms and transmits location information of the detected underground facility so that it is displayed on map information.

At this time, the QR reader 20 and display 22 are installed on the detection unit 30 so that the operator can directly check it with his or her eyes.

In particular, the QR reader 20 is a hand-held device and is used in the same form as a barcode reader so that the QR code can be read by holding it by hand and placing it on a QR code sign to be scanned.

In addition, the QR code information read by the QR reader 20 is displayed on the display 22, and the QR code information includes the type of buried object, the type of buried object, the buried depth, the buried date, the owner of the buried object, and the purpose of the buried object. , buried location (coordinate information), etc.

In addition, in the case of an existing underground facility without a QR code sign, after receiving information about the underground facility from the management server 10 based on the information detected by the detection unit 30, a QR code for the underground facility It would be even better if it included the work of creating, marking, and fixing it to the ground. To this end, the detection unit 30 may include a QR generator (not shown) in addition to the QR reader 20.

In addition, the detection unit 30 wirelessly communicates with a detection base unit (UT), a detection controller (C) mounted on the detection base unit (UT), and a management server 10 under the control of the detection controller (C). A wireless communicator (T), a GPS receiver (R) that communicates with a satellite under the control of the detection controller (C) and receives location information about the current detection point, and a buried underground facility under the control of the detection controller (C) It includes a GPR (Ground Penetrating Radar) detector (D) that detects at high frequencies, and a memory (M) that temporarily stores detection information, location information, and QR code scan information under the control of the detection controller (C).

At this time, the GPR detector (D) is a device that detects various structures and geological structures existing underground by using high-frequency electromagnetic waves and received signal processing methods to detect the location of objects. It was originally used for physical exploration purposes, but has recently been used. This is a well-known detection equipment used to detect the shape of underground facilities such as underground pipes.

And, when the underground facility is detected by the GPR detector (D), the detection controller (C) recognizes the shape and then transmits the shape to the management server (10) through the wireless communication device (T), and the management server ( 10) finds the corresponding shape information.

In addition, the detection controller (C) transmits the current location information received by the GPS receiver (R), that is, coordinate information, to the management server 10, and the management server 10 determines the location of the corresponding point in the map information. At the same time as displaying buried objects, information about their shape is also specified and displayed.

In this case, the display information is stored and managed in the map database, so it can be checked at any time.

At the same time, if there is information read by the QR reader 20, the detection controller C preferably transmits this information to the management server 10 so that it can be comprehensively managed.

In addition, it is more desirable to display the shape detected by the GPR detector (D) on one side of the display 22 so that the operator can confirm the exact location.

Meanwhile, as shown in the example of FIG. 2, the detector unit (UT) includes a wheel (W), a frame (31) axially fixed to the wheel (W) and obliquely extended, and horizontally extending from the top of the frame (31). a handle 32, a fixture 33 installed on the axis of the wheel W and rotatable supported on the ground to maintain the frame 31 in an erect state, and fixed to the frame 31 and A binding tool 34 for binding the fixing stand 33, a storage stand 35 protruding from the frame 31, a pneumatic tank 36 fixed to the storage stand 35, and the pneumatic tank 36. It includes a pump 37 that compresses and supplies air, and a pneumatic motor 38 that is rotated by receiving the air pressure from the pneumatic tank 36.

And, a control panel (P) is fixed to one side of the frame 31.

At this time, the control panel (P) is equipped with a detection controller (C), a memory (M), a GPS receiver (R), and a wireless communication device (T) in module form, and a GPS receiver (R) is installed at the top of the frame 31.
