Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The terms "unit", "module", "device", "terminal", "server", and "system" used in the embodiments may be a combination of hardware and software. The hardware may be a data processing device including a CPU or other processor, and the software may be a program running on the hardware.

The present invention relates to an apparatus for finding a broken position in an underground buried pipe, for example, a pipe buried underground.

The pipe according to the present invention may be a water supply pipe, a gas pipe, a communication line pipe, or the like. Hereinafter, a device for finding a leak location of a water pipe will be described as an example.

1 is a configuration diagram of the underground buried pipe position recognition device according to the present invention, Figure 2 is a schematic diagram showing the connection of the underground buried pipe position recognition device according to the present invention with a sensor.

The underground buried pipe position recognition device according to the present invention includes a terminal 300 carried by the field worker, and the management server 100 is connected to the communication terminal.

The management server provides the pipe setting information and the leak location information to the terminal.

The management server 100 according to the present invention includes a pipe setting beam storage unit 110, a leak location information acquisition unit 120, the control unit 130. In addition, the communication unit for transmitting data to the terminal may be further provided.

The pipe setting beam storage unit 110 stores the pipe setting beam displayed on the map data. The pipe buried setting information includes the coordinate information of the buried pipe, the buried pipe type information, and the material information of the buried pipe.

In one embodiment, the embedded pipe coordinates may be GPS coordinates.

As an embodiment, the type of the embedded pipe may be a water supply pipe, a gas pipe, a communication line pipe, or the like.

In an embodiment, the material of the embedded pipe may be steel, a copper pipe, a cast iron pipe, a plastic pipe, or the like.

Plumbing setting beam according to the present invention may include map data in which buildings, roads, railways and the like are displayed.

The leak location information acquisition unit 120 obtains leak location information based on vibration sound waves detected from the sensor. The leak location information may be a leak location coordinate, that is, a coordinate of a point where the leak occurs.

When the vibration sound waves detected from the sensor are vibration sound waves due to leakage, the leakage generation signal is output to the controller. Also, the leak position calculation unit calculates the leak position from the vibration sound waves.

The leak location may be calculated based on the pipe setting beam stored in the pipe setting beam storage unit.

For example, referring to FIG. 2, the A sensor S (A) and the B sensor S (B) are installed at positions separated from each other by a predetermined distance from the water supply pipe PW, and the A sensor and the B sensor. It is possible to detect the vibration sound waves due to the leakage occurring in between, that is, the leakage vibration sound waves.

When a leak occurs between the A sensor and the B sensor, the leak distances d1 and d2 from the A and B sensors are calculated based on the difference in the arrival time of the vibration sound waves generated by the leak.

As an example, the distance D between the A sensor and the B sensor may calculate the leak position CC by referring to the coordinate information of the buried pipe stored in the pipe setting beam storage unit.

In one embodiment, the transmission speed of the vibration sound wave may vary depending on the material of the pipe. The transmission speed of the vibration sound wave is obtained by referring to the material information of the embedded pipe stored in the pipe setting beam storage unit.

Subsequently, the leak position coordinates are acquired from the coordinate information of the buried pipe based on the coordinates of the A sensor, the B sensor, and the leak separation distance.

When the leak generation signal is transmitted from the leak location information acquisition unit, the controller 130 outputs a transmission request signal to the pipe setting information storage unit and the leak location information acquisition unit, respectively.

As an embodiment, the pipe setting beam storage unit transmits the pipe setting beam storage unit to the terminal according to the transmission signal of the controller, and the leak position information obtaining unit transmits the leaking position information to the terminal.

Such pipe sheet setting information and the leak location information can be transmitted to the terminal through the communication unit. The communication unit may be wired communication, wireless communication, 3G, 4G, or other communication method.

In one embodiment, the wired and wireless communication may be one or more communication methods selected from the group consisting of LAN, GSM, WCDMA, CDMA, Bluetooth, Zigbee, Wi-Fi, VoIP, LTE, and the like, and is not limited to these communication methods. .

In the present invention, the embodiment of the present invention transmits the pipe setting information and the leaking position information to the terminal in response to the leakage generation signal, but in another embodiment, the control unit transmits the pipe setting information to the terminal in advance, and the pipe setting setting information thus transmitted. May be stored in a storage space provided in the terminal. In this case, the controller may output a transmission request signal to the leak location information acquisition unit according to the leak generation signal. In addition, the control unit may transmit a leak occurrence signal to the management server manager according to the leak occurrence signal.

The terminal 300 according to the present invention receives pipe setting information and leakage location information from a management server, and provides detection probability information based on a point coordinate value input by a field operator.

The terminal according to the present invention includes a leakage area setting unit 310, a GPS module 320, an input area obtaining unit 330, a probability calculating unit 340, and a display unit 350. Additionally, the communication unit may receive a signal and data from the management server, and may further include a storage unit for storing information.

The leak area setting unit 310 sets a leak area based on the leak location information.

The leak location coordinates of the leak location information transmitted from the management server may not exactly match the location where the actual leak occurred. This is because the transmission speed of the vibration sound waves varies for various reasons such as the material of the pipe, the connecting member of the pipe, the number of connecting members, and the soil in which the pipe is buried.

The leak area setting unit sets a leak area having a predetermined estimated radius around the leak location coordinate.

Here, the estimated radius may be calculated according to the type of pipes and the number of pipes embedded in the corresponding leak position coordinates.

For example, if the water supply pipe, gas pipe, and communication line pipe are buried at the same leak location coordinates, the water pipe, gas pipe, and communication line can be set to have a larger area. If any one of the pipes is embedded, it can be set to have a narrower area.

3 is a view showing the plumbing pipe setting beam and the leak area shown on the screen of the terminal according to the present invention, the water supply pipe, gas pipe, communication line pipe is buried on the same line. By the way, it is shown that the water supply pipe in the upper side, the communication line pipe in the center, the gas pipe is buried in the lower side, it may be different from the actual buried state. For example, the gas pipe may be buried above, the communication line pipe may be buried below, and the communication line pipe may be buried below the gas pipe. It is difficult to know the location or arrangement of the underground until it is checked directly.

In the drawing, reference numeral LWA denotes a leakage region set according to the leakage position coordinate, and reference numeral CC denotes the leakage position coordinate.

The GPS module 320 receives a signal from the satellite and obtains the current position coordinates of the terminal. The location coordinates may be latitude and longitude coordinates.

The input area obtaining unit 330 receives GPS coordinates from a field operator and obtains an input area from the input GPS coordinates. In one embodiment, the input area may be a digging area for the site operator to find the leak location.

As an example, the field worker may input point coordinates according to an interface provided by the selected figure pattern. The figure pattern may be any one of a dot pattern, a line pattern, a quadrangle pattern, and a circle pattern.

As one embodiment, the point coordinates may be input through a touch input when the display unit 150 is a touch panel.

As an example, the point coordinates input by the field worker may be GPS coordinates.

The figure selection module receives a predetermined figure pattern. To this end, the figure selection module provides a figure button to the display unit. As an embodiment, the figure button may be any one of a dot button, a line button, a quadrangle button, and a circle button.

As an embodiment, the field worker may select one of the figure buttons from the figure buttons displayed on the display unit.

4 shows a figure selection window by the figure selection module. Referring to the drawings, a figure selection window shows a figure button that can be selected by the field worker.

The area acquisition module receives the point coordinates from the field worker and obtains an input area of the field worker.

As an embodiment, when the selected figure button is a point button, the first point coordinates may be input. In this case, the user input area may be first point coordinates. In this case, the first point coordinate may be used to find the leaking position coordinate.

As an embodiment, when the selected figure button is a line button, the first point coordinates may be input, and the second point coordinates spaced apart from the first point coordinates by a predetermined distance may be received. The input area of the user may be a line connecting the first point coordinates and the second point coordinates. In this case, a line connecting the first and second point coordinates may be used to check whether the pipe intersects the leaked pipe.

As an embodiment, when the selected button is a rectangular button, the first point coordinates may be input, and the second point coordinates spaced apart from the first point coordinates by a predetermined distance may be received. The user input area may be a rectangular area defined by using first point coordinates and second point coordinates as corner coordinates located on a diagonal of the rectangle. In this case, the blind spot may be used to check whether the leak location coordinates are included in the blind spot.

As an exemplary embodiment, when the selected button is a one button, the first point coordinates may be input, and the second point coordinates spaced apart from the first point coordinates by a predetermined distance may be received. The input area of the user may be a circle area having the first point coordinates as the center of the circle and the distance between the first point coordinates and the second point coordinates as a radius. In this case, the circle area may be used to check whether the leak location coordinates are included in the circle area.

5 illustrates receiving the point coordinates with a square button to obtain an input area corresponding to the square pattern.

In an embodiment, an input area corresponding to the rectangular pattern may be obtained from the first point and the second point coordinates.

Referring to the drawing, after the field operator selects the square button on the figure selection window, the terminal is stopped at the AA point and the touch point is input to the first point coordinate. Subsequently, the terminal is moved to the BB point and then touch inputs the second point coordinates at the BB point.

As such, when the first point coordinates and the second point coordinates are input, the area acquisition module of the terminal acquires a rectangular entry zone (WSA).

FIG. 6 illustrates that an input area corresponding to an original pattern is obtained by receiving point coordinates with a one button.

In an embodiment, an input area corresponding to the original pattern may be obtained from the first point and the second point coordinates.

Referring to the drawing, after the field worker selects the one button on the figure selection window, the terminal is stopped at the AA point and the touch point is input to the first point coordinate. Subsequently, the terminal is moved to the BB point and then touch inputs the second point coordinates at the BB point. At this time, the distance between the AA point and the BB point is a distance corresponding to the radius of the input area.

As such, when the first point coordinates and the second point coordinates are input, the area acquisition module of the terminal acquires a circular entry zone (WSA).

Hereinafter, the calculation of the probability of finding the leak location from the leak area and the input area will be described.

The probability calculator 340 calculates the probability of finding the leaked position in the digging work, that is, the estimated probability. The estimated probability is calculated as the ratio of the shared area of the input area to the leaked area. The probability calculator outputs the calculated estimated probability to the display.

The fault location coordinates used in the calculation of the leak area may have a predetermined error range. This is because it may occur for various reasons, such as the difference in the transmission speed of the vibration sound waves according to the medium, the delay time in the process of transmitting the detected vibration sound waves.

The probability calculation unit outputs an estimated probability that the field worker can find the actual leak in the area to be dug, that is, the input area, in consideration of the error range of the fault location coordinate.

As an example, when the output estimated probability is greater than or equal to a preset value, the digging operation may be started.

The display unit 350 displays a leak area, an input area, a leak location coordinate on a pipe buried map, and displays a calculated estimated probability. Here, the pipe buried map may be a map in which pipes are superimposed on the map. As an example, in order for an on-site worker to easily distinguish the types of pipes, respective pipes such as a water pipe, a gas pipe, a communication line pipe, and the like may be displayed in different colors, and may be displayed by dividing lines of different shapes.

Fig. 7 shows the estimation probability by setting the shared area from the leaked area and the input area. In the drawing, the actual leak position coordinate may be different from the actual leak point. The leak location coordinates displayed on the display unit mean a location predicted to be a leak point by a site worker.

In step S200, when a leak occurs in the pipe, the management server calculates the leak position coordinates from the vibration sound waves according to the leak, and transmits the leak position information including the leak position coordinates to the terminal. The terminal obtains the leak location coordinates from the leak location information.

Subsequently, in step S300, the terminal sets a leaking area having a predetermined estimated radius around the leaking position coordinate. As an example, the estimated radius may be calculated according to the type of pipes and the number of pipes buried close to the leaking position coordinate.

In an embodiment, an input area corresponding to a predetermined shape is obtained from point coordinates. In this case, the input area may be a digging area for the site worker to find the leak location point.

Finally, in step S400, the ratio of the shared area of the input area to the leaked area is calculated. The calculated ratio is then output to the display. The field worker may start digging to find the leak location point when the output rate is more than a predetermined rate.
