[0001] APPARATUS AND METHOD FOR DETECTING WATER LEAKS [0002]

The present invention relates to a leakage detection apparatus and method, and more particularly, to a leakage detection apparatus and method for detecting a leakage based on data collected through at least one sensor and remotely controlling the flow rate through wireless communication .

Generally, tap water is treated in a water purification plant and then supplied through a large pipe in each case in the case of city. In each case, tap water is classified into small blocks and small blocks.

A water meter is installed between each dispensing point to measure the flow rate of tap water supplied to the dispensing area. Large-scale facilities such as apartment complexes are also equipped with water pipes to supply tap water at the same time through a large pipe.

In addition, in the case of general households and densely populated areas, a small pipe is connected to a large pipe buried under the road to supply tap water to the end use place. At this time, when a small pipe is referred to as a "branch," most leaks occur in the branch line. In other words, the branch wire has a large pressure due to a small tube, and in a dense housing area, it is connected by a joint or the like so that leakage is easily generated at the joint and the connection part.

It is known that about 20% or more of tap water as a whole is wasted due to leaking water when the leakage amount generated from each branch line is counted as a whole. As a result of such a large amount of tap water leaking, foreign substances, bacteria, heavy metals, etc. are introduced into the water pipe due to a change in pressure at the water leakage position as well as a waste of cost. Further, in order to check such leakage, the manager has to directly check the piping embedded in the underground.

Hereinafter, the terms are defined in consideration of donation in the present invention, which may vary depending on the intention of the user, the intention or the custom of the operator.

However, the present invention is not limited to the embodiments described below, but may be embodied in various forms. These embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art to which the present invention pertains.

Hereinafter, a wig washer according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a flowchart showing a flow control method in a flow control system according to an embodiment of the present invention. The flow control system includes a water leakage sensing device 110 and a monitoring device 130.

The water leakage sensor 110 collects data through the image sensor and the vibration sensor (S101). At this time, the image sensor collects data on the flow rate information and the surrounding state information by photographing the flow meter installed in the pipe and the surrounding, and collects data on the vibration information of the pipe through the vibration sensor.

The leakage sensing device 110 stores the collected data (S103), and extracts analysis data based on the stored data (S105). At this time, the analysis data is data necessary for determining whether or not the water leakage occurs. The data for the flow rate information and the surrounding state information and the data for the vibration information are synthesized by software. Specifically, the analysis data is obtained by checking the flow pressure, flow rate, and flow rate measurement information of the pipe through the data on the flow rate information and the surrounding state information, and the vibration amplitude, amplitude , And tone color information, respectively.

Thereafter, the water leakage sensing device 110 determines whether or not the water leakage occurs based on the extracted analysis data (S107). If it is determined that no water leakage has occurred, steps 101 to 107 are continuously repeated.

If it is determined that a leak has occurred, a leakage notification message is generated and the generated leak notification message is transmitted to the monitoring device 130 (S109).

When the monitoring device 130 receives the leak notification message from the leak detection device 110, the monitoring device 130 stores the leak notification message (S111). The leak notification message includes analysis data extracted from the leak detection device 110.

Thereafter, the monitoring device 130 generates a control value for controlling the flow rate based on the information included in the stored leak notification message (S113), and transmits the generated control value to the leakage detection device 110 (S115) .

When the water leakage sensing device 110 receives the control value for controlling the flow rate from the monitoring device 130, the received control value is stored to be used for the subsequent flow rate control (S117).

Here, the water leakage sensing device 110 and the monitoring device 130 transmit / receive data based on wireless communication, whereby the monitoring device 130 can remotely control the water leakage sensing device 110.

2 is a block diagram showing a configuration of a leakage detection device according to an embodiment of the present invention.

2, the water leakage sensing apparatus 110 mainly includes a transmission / reception unit 201, a collection unit 203, an extraction unit 205, a determination unit 207, a storage unit 209, and a control unit 211, .

The collecting unit 203 includes at least one sensor, and collects data about the piping and the periphery of the piping through each sensor. At this time, the at least one sensor may be an image sensor, a vibration sensor, a pressure sensor, a temperature sensor, a noise sensor, or the like.

The extracting unit 205 analyzes the data collected by the collecting unit 203 and extracts analysis data for determining whether or not to leak.

For example, when the image sensor and the vibration sensor are provided in the collecting unit 203, the collecting unit 203 collects data on the flow rate information and the surrounding state information through the image sensor, And the extracting unit 205 extracts the analysis data by separating the vibration amplitude, amplitude, and tone color information of the pipe based on the collected information.

The determination unit (207) determines whether or not to leak based on the analysis data extracted by the extraction unit (205). At this time, the determination unit 207 compares the analysis data with the previously stored information data, which is a criterion for determining whether or not the leak is leaked, to determine whether or not the leak is present. In this case, the determination unit 207 determines whether or not the change in the flow rate pressure and the tone color frequency pattern at the time of leakage included in the previously stored information data are identical to each other Thereby judging whether or not the leak occurs.

The storage unit 209 stores data collected through at least one or more sensors provided in the collecting unit 203, stores analysis data extracted based on the stored data, and further includes a leakage sensing device 110 And stores various data necessary for driving.

The control unit 211 extracts analysis data based on the collected data, and determines whether or not to leak based on the extracted analysis data and the previously stored information data. If it is determined that leakage has occurred, To the monitoring device, and controls to receive and store a control value for controlling the flow rate from the monitoring device in response to the analysis data.

Thereafter, the flow rate is controlled by the stored control value.

3 is a view showing a leakage detection method in the leakage detection device according to the embodiment of the present invention.

3, the collecting unit 203 collects the flow rate information and the surrounding state information by photographing the flow meter and the surrounding state through the image sensor (S301), and the extracting unit 205 extracts the flow rate information and the flow rate information The first analysis data is extracted based on the surrounding state information and stored in the storage unit 209 (S303).

Thereafter, the collecting unit 203 collects the vibration information through the vibration sensor and stores it in the storage unit 209 (S305). The extracting unit 205 extracts the second analysis data based on the first analysis data and the vibration information (S307).

At this time, the flow information and the surrounding state information include information on the flow pressure of the pipe, the flow rate, information on the flow rate measurement, and the state of the manhole, and the vibration information includes information on the vibration amplitude, .

The determination unit 207 determines whether or not the leaking water is leaked by comparing the change of the flow rate pressure included in the second analysis data with the leak sound color frequency pattern included in the stored information data (S309).

As a result of the determination, if the change in the flow rate of the flow rate does not match the leakage tone frequency pattern of the previously stored information data, it is determined that no leakage has occurred, and the flow returns to step S301, .

As a result of the determination, if the change in the flow rate pressure and the leakage sound frequency pattern match, it is determined that a leak has occurred and a leak notification message is generated. The transmitter / receiver 201 transmits the generated leak notification message to the monitoring device 130 (S311).

At this time, the leak notification message includes the second analysis data, and the administrator can check the status of the piping through the leak notification message received by the monitoring device 130. [

Thereafter, when the transmission / reception unit 201 receives the control value for controlling the flow rate in response to the leak notification message (S313), the received control value is stored in the storage unit 209 (S315).

This allows the flow rate to be controlled based on the stored control value.

It is to be understood by those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.
