An object of the present invention is to provide a portable water pipe water leak sound collecting device and a leak sound management operating system using the same, since it can be used by mounting the terminal.
상수도 배관은 지중에 매설되어 운영되는데, 지진, 침하, 상부 압박 등에 의해 파손되어 누수가 발생된다. 특히 이러한 상수도 배관은 도로의 밑에 위치되는 경우가 많으므로, 차량의 통행에 따라 지속적으로 압박을 받게 되어 파손되는 문제가 있었다.Waterworks pipelines are operated underground, but they are damaged due to earthquakes, subsidence, and upper pressure, resulting in leakage. In particular, since these waterworks pipes are often located under the road, they are constantly under pressure according to the passage of vehicles, and thus there is a problem of damage.
이러한 상수도 배관의 누수는 수자원의 낭비 뿐만 아니라, 누수 지역의 지반 약화 등 다양한 문제가 있으므로, 누수 부위를 신속하게 보수하는 것이 중요하다.Since such a water leak in the water supply pipe has various problems, such as not only waste of water resources, but also weakening of the ground in the leaking area, it is important to repair the leaking part quickly.
그러나, 상수도 배관은 대부분 지중에 매설되어 있으므로, 종래에는 막대형의 청음봉 일단을 지면에 접촉시키고 타단을 귀에 꽂아 청음봉을 타고 전파되는 지중의 소음을 통해 누수 여부를 확인하였다.However, since most of the waterworks pipes are buried underground, in the prior art, one end of a rod-shaped listening rod was placed in contact with the ground and the other end was inserted into the ear to check for leakage through the underground noise propagating through the listening rod.
그러나, 이러한 청음봉을 이용한 방식은 작업자의 숙련도에 따라 오탐율이 10% 내지 80%가 되는 등 숙련된 작업자가 반드시 필요한 문제가 있었다.However, the method using such a hearing rod has a problem that a skilled worker is necessarily required, such as a false positive rate of 10% to 80% depending on the skill level of the operator.
따라서, 비전문가도 누수 탐사 업무를 수행할 수 있고, 누수음의 분석을 정확하게 할 수 있는 시스템의 개발이 필요로 하게 되었다.Therefore, it is necessary to develop a system that allows non-experts to perform leak exploration work and accurately analyze leak sound.

휴대용 단말(200)은, 누수음 수집 장치(100)로부터 음파 센서의 측정값을 전송받아 누수의 발생 여부를 판별하는 역할을 한다. 이를 위한 휴대용 단말(200)은 누수음 수집 장치(100)의 통신부와 블루투스 또는 와이파이 통신이 가능하고, 원격지의 서버와 상용 이동통신 회선을 통해 통신 가능하며, 누수음 판별을 위한 소프트웨어의 탑재가 가능하고 정보 처리 결과를 디스플레이할 수 있는, 통상의 스마트폰 또는 태블릿PC가 그 대상이 될 수 있다. 또한, 이러한 휴대용 단말(200)은 측정 장소의 위치 좌표를 생성할 수 있도록 GPS 모듈이 구비된다.The portable terminal 200 receives the measurement value of the sound wave sensor from the water leak sound collection device 100 and determines whether water leakage occurs. For this purpose, the portable terminal 200 is capable of Bluetooth or Wi-Fi communication with the communication unit of the water leak sound collecting device 100, and can communicate with a remote server through a commercial mobile communication line, and it is possible to install software for water leak detection And a normal smartphone or tablet PC that can display the information processing result can be the target. In addition, the portable terminal 200 is provided with a GPS module to generate the location coordinates of the measurement location.
휴대용 단말(200)은, 음파 센서의 측정값을 주파수 데이터로 변환한 후, 주파수 데이터로부터 패턴을 추출하여, 추출된 패턴과 과거 누수음 데이터를 기반으로 설정된 누수 의심 주파수 패턴을 비교하여 유사도가 설정 비율 이상이면 누수가 발생된 것으로 판별한다.The portable terminal 200 converts the measurement value of the sound wave sensor into frequency data, extracts a pattern from the frequency data, compares the extracted pattern with a leak suspicious frequency pattern set based on past leak sound data, and sets the similarity If it is more than the ratio, it is determined that a leak has occurred.
이러한 휴대용 단말(200)의 누수 발생 여부 판별 과정을 살펴보면, 우선 휴대용 단말(200)은 누수음 수집 장치(100)로부터 음파 센서의 측정값 또는 그로부터 생성된 음성 파일을 전송받는다. 이때, 휴대용 단말(200)에 전송된 데이터는 음파 센서로부터 측정된 소리의 데이터이므로 시계열로 가변되는 파형 형태를 갖는다. 이러한 시계열 파형은 잡음 성분이 누수음 성분에 더해져 파형의 왜곡이 발생하므로, 이를 잡음 성분과 누수음 성분으로 분리하고, 또한, 특정 패턴을 추출하기가 어려우므로, 이를 주파수 계열 파형으로 변형할 필요가 있다. 이러한 주파수 계열의 변환을 위하여 고속 푸리에 변환(FFT: Fast Fourier Transform)이 활용된다. FFT는 주파수가 서로 다른 사인파가 중첩된 파형에서 각 사인파의 주파수별로 진폭을 특정할 수 있으며, FFT의 수행 방법은 널리 알려진 공지의 기술이므로 상세한 수식은 생략하도록 한다.Looking at the process of determining whether a water leak has occurred in the portable terminal 200 , first, the portable terminal 200 receives a measurement value of the sound wave sensor or a voice file generated therefrom from the water leakage sound collecting apparatus 100 . At this time, since the data transmitted to the portable terminal 200 is data of sound measured by the sound wave sensor, it has a waveform shape that varies in time series. In such a time series waveform, since a noise component is added to a leaky sound component and distortion of the waveform occurs, it is separated into a noise component and a leaky sound component, and it is difficult to extract a specific pattern, so it is not necessary to transform it into a frequency series waveform have. A Fast Fourier Transform (FFT) is used to transform the frequency series. The FFT can specify the amplitude for each frequency of each sine wave in a waveform in which sine waves of different frequencies are superimposed. Since the FFT method is a well-known technique, detailed formulas will be omitted.
휴대용 단말(200)은 전송된 측정값으로부터 FFT를 수행하여 시계열 데이터를 주파수 데이터로 변환한다. 그리고 주파수 데이터로부터 패턴을 추출하고, 추출된 패턴과 과거 누수음 데이터를 기반으로 설정된 누수 의심 주파수 패턴을 비교하여 유사도가 설정 비율 이상이면 누수가 발생된 것으로 판별한다.The portable terminal 200 converts time series data into frequency data by performing FFT on the transmitted measurement value. Then, a pattern is extracted from the frequency data, and the extracted pattern is compared with a leak suspicious frequency pattern set based on past leak sound data, and if the similarity is greater than or equal to a set ratio, it is determined that a leak has occurred.
배관에 누수가 발생되었을 때에는 배관 내에 정상적으로 물이 흐를때와 다르게 특정 주파수 대역의 피크가 높게 형성되는데, 이러한 누수시의 피크가 형성된 주파수 대역의 주파수, 피크값 등이 패턴 형성의 대상이 된다. 따라서, 측정 위치에서 측정되어 변환된 주파수 패턴이 과거에 누수가 실제 발생되었던 사례들의 주파수 패턴과 유사한 경우 누수가 발생된 것으로 판별하는 것이다. 이때 유사도의 계산은 어느 주파수 대역에서 어떠한 피크값을 갖는지, 해당 주파수 대역이 다른 주파수 대역보다 몇 배 큰 피크값을 갖는지 등을 비교하여 비교 대상이 되는 주파수 대역 대비 조건을 만족하는 주파수 대역의 총 비율로서 확인하는 방법이 그 일례가 될 수 있다.When a water leak occurs in a pipe, a peak in a specific frequency band is formed to be high, unlike when water normally flows in the pipe. The frequency and peak value of the frequency band where the peak is formed at the time of leakage become the target of pattern formation. Therefore, when the frequency pattern measured and converted at the measurement location is similar to the frequency pattern of cases in which the leak has actually occurred in the past, it is determined that the leak has occurred. At this time, the similarity is calculated by comparing which frequency band has which peak value and how many times larger peak value than that of other frequency bands, etc. An example of this may be a method of confirming as .
그러나, 상수도 배관은 지중에 매설되는 경우가 대부분이고, 또한, 배관은 합성수지, 금속 등의 다양한 재질로 형성되며, 배관이 매설된 주변의 지질, 도로 포장 상태, 근처의 대형 건물의 유무 등에 의해 누수 발생시의 주파수 패턴이 측정 위치에 따라 천차 만별일 수 있다.However, in most cases, the water supply pipe is buried underground, and the pipe is formed of various materials such as synthetic resin and metal, and it leaks due to the surrounding geology, the road pavement condition, the presence or absence of a large building nearby, etc. The frequency pattern at the time of occurrence may be very different depending on the measurement location.
예를 들어, A도시의 도심 지형, 20층 이상 고층 빌딩 10개소, 주변 상가 100개소인 종래의 측정값 패턴 및 누수음 정보가 있는 상태에서, B도시의 도심 지형, 20층 이상 고층 빌딩 9개소, 주변 상가 80개소인 신규 측정 위치가 있는 경우, A도시의 측정값 패턴 및 누수음 정보를 B도시에도 초기에 유사하게 적용할 수 있는 것이다. 만일, 이러한 초기 패턴 정보 또는 누수음 정보 없이 B도시를 신규 측정하는 경우, B도시의 관로가 이미 누수가 발생된 후라면, 누수가 발생중인 음을 측정하여 패턴을 형성하고 향후로도 이 패턴을 활용하여 누수 여부를 판별해야 하기 때문에, 누수 부위에 변동이 발생하지 않는 한 누수 여부를 판별하기 어렵기 때문이다.For example, with the urban topography of city A, 10 high-rise buildings with 20 stories or more, and the conventional measurement value pattern and water leak information of 100 surrounding shopping malls, the urban topography of city B, 9 high-rise buildings with 20 stories or more , if there is a new measurement location of 80 nearby shopping malls, the measurement value pattern and leak sound information of city A can be similarly applied to city B at the beginning. If city B is newly measured without such initial pattern information or leak sound information, if the pipeline in city B has already leaked, a pattern is formed by measuring the leaking sound, and this pattern will be used in the future as well. This is because it is difficult to determine whether there is a leak unless there is a change in the leaking part because it must be used to determine whether there is a leak.
또한, 이러한 위치 정보 및 시설물 정보에 근거한 초기 패턴 및 누수음 정보는 측정 사례가 거듭될수록 더욱 세분화되고 정밀해져, 신규 측정 위치에서의 측정도 더욱 정밀해지는 효과를 갖게 된다.In addition, the initial pattern and leak sound information based on the location information and facility information become more subdivided and precise as the measurement cases are repeated, so that the measurement at the new measurement location also has the effect of becoming more precise.
이때, 측정값 패턴은 관종 또는 시설물이 서로 유사한 경우에도 관로가 매설된 깊이, 관로가 매설된 지점의 지질 등에 따라 변수가 다양하기 대문에, 신규 측정 위치에서는 우선 해당 지역에 누수가 이미 발생되었는지의 여부를 확인하는 것에 초점을 맞추는게 바람직하다. 관로의 평상시 소음에 비해 누수음은 그 주파수 스펙트럼 패턴이 비교적 특징적으로 나타나기 때문에, 신규 측정 위치에서는 기 누수의 여부만을 판별하고, 새로이 측정되는 측정값으로부터 해당 위치만의 측정값 패턴을 형성할 수 있도록 하는 것이 바람직하다. 이를 위하여, 서버는 어느 측정 위치에서 누수가 발생된 것으로 판별되면, 해당 측정 장소의 위치 정보 및 시설물 정보를 토대로 해당 위치에서의 관종별 또는 시설물별 누수음 정보를 보정하여 저장하고, 신규 측정 위치에서의 누수 판별시에 신규 측정 위치의 시설물 정보를 토대로 추출된 관종 또는 시설물에 대응되는 누수음 정보의 초기 패턴으로 적용하게 된다. 이때의 휴대용 단말(200)은 신규 측정 위치에서의 측정값이 초기 패턴으로 저장된 누수음 패턴과 유사도가 설정 비율 이상인 경우 해당 측정값을 누수가 발생된 것으로 판별하게 된다.At this time, since the measured value pattern varies according to the depth at which the pipe is buried, the geology of the point where the pipe is buried, etc., even if the pipe type or facilities are similar, first of all, at the new measurement location, it is necessary to determine whether a leak has already occurred in the area. It is better to focus on checking whether or not Since the frequency spectrum pattern of the leak sound is relatively characteristic compared to the normal noise of the pipeline, it is possible to determine only whether there is a leak at the new measurement location, and to form a measurement value pattern only for that location from the newly measured values. It is preferable to do To this end, when it is determined that a leak has occurred at a certain measurement location, the server corrects and stores the leak sound information for each pipe type or facility at the location based on the location information and facility information of the measurement location, and stores it at the new measurement location. When determining the leak of , it is applied as an initial pattern of leak sound information corresponding to the pipe type or facility extracted based on the facility information of the new measurement location. At this time, the portable terminal 200 determines that the measured value has leaked when the similarity with the leak sound pattern stored as the initial pattern is greater than or equal to the set ratio of the measured value at the new measuring position.
따라서, 이를 정리해보면, 휴대용 단말(200)은 음파 센서의 측정값의 전송시에 음파 센서의 측정값이 생성된 장소의 위치 좌표를 서버에 전송한다. 그리고, 휴대용 단말(200)에는 현재 측정하려는 장소의 위치 좌표에 대응되는 관종 정보 또는 시설물 정보가 기 저장되거나, 또는, 서버로부터 해당 위치 좌표에 대응되는 관종 정보 또는 시설물 정보가 전송되어 저장되며, 측정되어 추출된 주파수 패턴과 관종 정보 또는 시설물 정보에 대응되는 누수 의심 주파수 패턴을 비교하여 누수 여부를 판별하게 되는 것이다.Therefore, to summarize, the portable terminal 200 transmits the location coordinates of the place where the measurement value of the sound wave sensor is generated to the server when the measurement value of the sound wave sensor is transmitted. In addition, the portable terminal 200 pre-stores information on the type of office or facility information corresponding to the location coordinates of the place to be currently measured, or transmits and stores information on the type or facility of the facility corresponding to the location coordinates from the server. By comparing the extracted frequency pattern with the suspected leak frequency pattern corresponding to the pipe type information or facility information, it is determined whether there is a leak.
그리고, 서버는, 측정값이 생성된 위치 좌표에 대응되는 지점에서 실제 누수가 발생된 것으로 보고되면, 측정되어 추출된 패턴을 이용하여 관종 정보 또는 시설물 정보에 대응되는 누수 의심 주파수의 패턴을 보정하여 저장하게 된다. 또한, 이러한 사례가 반복될수록, 해당 지역에서의 누수 의심 주파수의 패턴이 정확해질뿐만 아니라, 어느 지질, 어느 관종, 어느 매설 깊이, 어느 시설물 근처 등의 보다 세분화된 파라미터들에 대해서도 충분한 데이터를 축적할 수 있으며, 이를 통해 신규 지역에서 처음 측정을 하는 경우에도 해당 신규 지역의 조건에 부합하는 누수 의심 주파수 패턴을 제공할 수 있게 되는 것이다.And, when it is reported that an actual leak has occurred at a point corresponding to the location coordinates where the measured value is generated, the server uses the measured and extracted pattern to correct the pattern of the suspected leak frequency corresponding to the pipe type information or facility information. will be saved In addition, the more these cases are repeated, the more accurate the pattern of suspected leak frequencies in the area will be, and sufficient data will be accumulated for more detailed parameters such as which geology, which type of pipe, which burial depth, and which facility is near. Through this, even when the first measurement is performed in a new area, it will be possible to provide a frequency pattern with a suspected leak that meets the conditions of the new area.
휴대용 단말(200) 또는 서버의 모니터링 장치에는 누수 여부를 측정한 장소가 지도상에 표시가 되고, 해당 지점을 선택하면 누수음을 청음할 수 있거나 누수 데이터의 주파수 계열 패턴을 확인할 수 있다.In the portable terminal 200 or the monitoring device of the server, the location where the leak is measured is displayed on the map, and when the corresponding point is selected, a leak sound can be heard or a frequency sequence pattern of the leak data can be checked.
또한, 휴대용 단말로부터 누수가 발생된 것으로 판별된 결과가 출력되면, 해당 측정 위치의 주변에 설정 간격으로 추가 측정이 이루어지고, 추가 측정 지점들 중 패턴의 피크값이 가장 큰, 즉, 누수음이 가장 크게 발생되는 지점의 도출이 가능해지게 되고, 해당 지점의 위치 좌표가 서버에 전송되면, 서버에는 누수음이 가장 크게 발생되는 지점의 시설물 정보 또는 관종 정보에 대응하여 누수 발생 위치를 특정하고 해당 지점의 굴착, 실제 누수 확인 및 보수 공사가 이루어지게 된다.In addition, when the result determined that water leakage has occurred is output from the portable terminal, additional measurements are made at set intervals around the corresponding measurement location, and the peak value of the pattern among the additional measurement points is the largest, that is, the leak sound. It becomes possible to derive the point where the biggest occurrence occurs, and when the location coordinates of the point are transmitted to the server, the server specifies the location of the leak in response to the facility information or the pipe type information of the point where the leak sound is the most and identifies the location of the point. excavation, actual leak check and repair work will be carried out.

또한, 본 발명은, 측정값을 관종 정보 또는 시설물 정보에 매칭하여 저장하므로, 신규 측정 위치에서 이미 누수가 진행중인 경우에도 유사한 관종 정보 또는 시설물 정보를 갖는 지역의 누수음 데이터를 이용하여 누수 여부를 판별할 수 있는 효과가 있다.In addition, since the present invention stores the measured value by matching it with pipe type information or facility information, even if water leakage is already in progress at the new measurement location, it is determined whether water leaks by using water leak data from an area having similar pipe type information or facility information. There is an effect that can be done.
또한, 본 발명은, 휴대용인 누수음 수집 장치(100) 및 휴대용 단말(200)을 이용하여 위치 정보에 대응되는 위치에서 측정만 진행하여도 측정값의 누적 및 누수 여부의 판별이 가능하므로, 모든 지중 관로마다 측정 장치를 구비하지 않아도 되는 효과가 있다.In addition, according to the present invention, since it is possible to determine the accumulation and leakage of measured values by only performing measurement at a location corresponding to location information using the portable water leak sound collecting device 100 and the portable terminal 200, all There is an effect that it is not necessary to provide a measuring device for each underground pipe.
또한, 본 발명은, 누수음 수집 장치(100)에 휴대용 단말(200)을 거치하여 활용 가능하므로, 파지가 용이하고 측정자의 손을 자유롭게 사용할 수 있는 효과가 있다.In addition, since the present invention can be utilized by mounting the portable terminal 200 on the leak sound collecting device 100 , it is easy to hold and the hand of the measurer can be freely used.
