Leakage management system and leakage location prediction method using same

Abstract

The present invention relates to a leakage management system and a leakage location prediction method. The leakage management system, according to the present invention, comprises: detection units (100-N) which are installed on a pipe and acquire and detect a skywave RF and a vibration sound wave; a management server (200) which learns data on the variation of the vibration sound wave according to the change in time, and outputs pipe state information and vibration sound wave location information; and a terminal (300) which visually provides a detection mark in accordance with the pipe state information and the vibration sound wave location information. The leakage location prediction method, according to the present invention, comprises the steps of: acquiring a leakage model by learning collected leakage data (S100); receiving a skywave RF and a vibration sound wave from detection units (S200); by using the leakage model, outputting pipe state information from the received vibration sound wave (S300); and outputting vibration sound wave location information from the received skywave RF and vibration sound wave (S400).

Description

technical field [0001] The invention relates to a water leakage management system and a method for predicting a water leakage location based on detected vibration and sound waves. Background technique [0002] With the improvement of living standards, water consumption increases year by year. The tap water pipes used for water supply are generally buried underground, and the buried tap water pipes leak due to various factors such as impact and aging. Although much effort and research has been done to find where a water leak occurs, it is not easy to pinpoint exactly where a water leak occurs. [0003] As a method for finding a water leak location, there are acoustic detection methods, correlation detection methods, and the like. The correlation detection method is a method of finding the location of the water leakage by installing acoustic sensors on both sides of the water pipe and calculating the arrival time difference of the water leakage sound detected by the sensors ...

Problems solved by technology

[0004] However, due to various factors such as the material of the water pipe, the amount of water in the water pipe, the state of the soil around the water pipe, and the connection port of the water pipe, the propagation speed of the sound of the water leak varies, so it is difficult to find the exact location of the water leak.
