Description

Multi-diagnostic system and method for simultaneously measuring the degree of corrosion and water quality of drinking water supply pipes

[0001] The present invention relates to drinking water management, and more particularly, to a multi-diagnostic system and method for simultaneously measuring the degree of corrosion and water quality of drinking water supply pipes, which enables simultaneous pipe corrosion inspection and water quality inspection using a scanning ultrasonic microscope.

[0002] Typically, drinking water supply pipes are made primarily of metal, such as cast iron or steel.

[0003] In particular, cast iron pipes, the most commonly used in drinking water supply worldwide, age over time and corrode easily. This leads to the formation of iron oxide-like corrosion. This corrosion affects water quality, releasing iron oxide particles into the water, degrading its quality.

[0004] In this way, cast iron drinking water pipes corrode over time, causing iron oxide particles to flow into drinking water, lowering water quality and causing harm to the human body when consumed.

[0005] Therefore, a non-destructive and continuous method for testing corrosion and water quality in drinking water supply pipes is needed.

[0006] Non-Destructive Testing (NDT) is a non-destructive testing technology that finds defects without damaging the target and has been studied in various fields such as optics, ultrasonics, and sensors.

[0007] Iron oxide suspended in water supply pipes, which results from corrosion, contaminates the water inside the pipes, but there are not many technologies to detect the presence of contamination and the degree of water quality.

[0008] Therefore, there is a need to develop a new technology that can non-destructively and continuously monitor the degree of corrosion in drinking water supply pipes and the amount of iron oxide mixed in the water simultaneously.

[0009] The present invention is intended to solve the problems of conventional drinking water supply devices and drinking water management technologies, and provides a multi-diagnosis system and method for simultaneously measuring the degree of corrosion and water quality of drinking water supply pipes, which enable simultaneous pipe corrosion inspection and water quality inspection using a scanning ultrasonic microscope.

[0010] The purpose of the present invention is to provide a multi-diagnostic system and method for simultaneously measuring the degree of corrosion and water quality of a drinking water supply pipe, which enables non-destructive testing and continuous measurement using a scanning ultrasonic microscope that scans a certain range using high-frequency ultrasonic waves, obtains a large number of ultrasonic signals, and images them.

[0011] The present invention aims to provide a multi-diagnosis system and method for simultaneously measuring the degree of corrosion and water quality of a drinking water supply pipe, which can precisely check the degree of corrosion of a drinking water supply pipe using a scanning ultrasonic microscope and simultaneously measure water quality, thereby improving the efficiency of a drinking water supply device and drinking water management.

[0012] The present invention aims to provide a multi-diagnostic system and method for simultaneously measuring the degree of corrosion and water quality of drinking water supply pipes, which overcomes the limitations of non-destructive testing methods by measuring the thickness of the pipe using a sound-attenuating microscope (SAM) to determine the degree of corrosion, and classifies the concentration of iron oxide particles in water using integrated backscattered (IB) analysis to measure water quality, thereby enabling more accurate and reliable simultaneous pipe corrosion degree and water quality tests.

[0013] The present invention aims to provide a multi-diagnostic system and method for simultaneously measuring the degree of corrosion and water quality of drinking water supply pipes, thereby increasing the efficiency of water quality management and pipe corrosion prevention through precise corrosion measurement using ultrasonic waves and automatic classification of iron oxide particles through IB (integrated backscattered) analysis, and reducing the maintenance cost of drinking water supply systems and increasing the efficiency of water quality management by providing accurate and reliable data.

Therefore, the terms used in this disclosure should not be defined simply as names, but rather based on the meanings of the terms and the overall content of the disclosure.

The peripheral devices may include a data input device, a data output device, and a data storage device.

[0040] A multi-diagnostic system and method for simultaneously measuring the degree of corrosion and water quality of a drinking water supply pipe according to the present invention enables simultaneous pipe corrosion inspection and water quality inspection using a scanning ultrasonic microscope.

[0041] To this end, the present invention may include a configuration that enables non-destructive testing and continuous measurement using a scanning ultrasonic microscope that scans a certain range using high-frequency ultrasonic waves to obtain a large amount of ultrasonic signals and image them.

[0042] The present invention may include a configuration that enables precise detection of the degree of corrosion in a drinking water supply pipe using a scanning ultrasonic microscope and simultaneous measurement of water quality, thereby improving the efficiency of a drinking water supply device and drinking water management.

[0043] The present invention can include a configuration that overcomes the limitations of non-destructive testing methods by measuring the thickness of a pipe using a sound-attenuating microscope (SAM) to determine the degree of corrosion, and classifies the concentration of iron oxide particles in water using integrated backscattered (IB) analysis to measure water quality, and allows for more accurate and reliable pipe corrosion degree testing and water quality testing to be performed simultaneously.

[0044] In the description below, A-Scan is a window that represents the time (μs) for an ultrasonic wave to be reflected and returned on the horizontal axis and the signal amplitude (%) on the vertical axis, indicating the size and distance of the ultrasonic reflection signal, and B-Scan is a window that displays the Y (Scan) axis cross-section of the inspection target based on the ultrasonic signal data acquired by A-Scan.

[0045] A multi-diagnosis system for simultaneously measuring the degree of corrosion and water quality of a drinking water supply pipe according to the present invention comprises, as shown in FIG. 1, a pipe scanning unit (10) that sets measurement parameters for measuring the degree of corrosion and water quality of a drinking water supply pipe, performs a pipe scan using a scanning acoustic microscope, and outputs A-scan results and B-scan results, a pipe corrosion measurement module (20) that measures the degree of corrosion of a pipe by using the difference in acoustic parameters due to the difference in thickness between the pipe and the corroded portion using the B-scan results, and a water quality measurement module (30) that measures water quality by analyzing a signal reflected from an ultrasonic signal inside the pipe using the A-scan results.

[0046] Here, the multi-diagnosis system for simultaneously measuring the degree of corrosion and water quality of a drinking water supply pipe according to the present invention may further include a measurement result learning unit (40) that learns the measurement results of the pipe corrosion measurement module (20) and the water quality measurement module (30) to optimize the measurement parameters.

[0047] And the water quality measurement module (30) measures water quality by classifying the concentration of iron oxide (Fe304) particles in water using IB (integrated backscattered) analysis.

[0048] The scanning acoustic microscope used in one embodiment of the present invention is a device that obtains and images ultrasonic signals from all parts within the range by scanning a certain range at one time.

[0049] Since scanning acoustic microscopes use single-element ultrasonic transducers, high-frequency transducers can be used, and due to the nature of ultrasound, the higher the frequency of the transducer, the better the resolution.

[0050] Scanning acoustic microscopy is suitable for various analysis methods because it can obtain a lot of data at once, and it can obtain not only B-scans that visualize the obtained data, but also A-scans that can be used for data analysis.

[0051] The multi-diagnosis system for simultaneously measuring the degree of corrosion and water quality of a drinking water supply pipe according to the present invention photographs a water supply pipe using a scanning acoustic microscope, confirms the degree of corrosion of the pipe through B-scan, and simultaneously obtains ultrasonic reflection signals from the water in the pipe and classifies them through IB (integrated backscattered) to diagnose the water quality.

[0052] In this way, by simultaneously measuring pipe corrosion and water quality, it is possible to simultaneously determine when to replace the pipe and the quality of the drinking water currently flowing inside the pipe.

[0053] And the pipe corrosion measurement module (20) includes a pipe corrosion measurement unit (20a) that measures the degree of corrosion of a pipe by using the difference in acoustic parameters due to the difference in thickness between the pipe and the area where corrosion has occurred using the B-scan results, and a pipe corrosion result output unit (20b) that outputs the measurement results of the pipe corrosion measurement unit (20a).

[0054] And the water quality measurement module (30) includes an internal ultrasonic data acquisition unit (30a) that receives the A-scan result and acquires internal ultrasonic data, an IB (integrated backscattered) analysis unit (30b) that classifies the concentration of iron oxide (Fe304) particles in water using IB analysis, and a water quality measurement result output unit (30c) that outputs a water quality measurement result based on the classification result of the iron oxide (Fe304) particle concentration in water of the IB analysis unit (30b).

[0055] The detailed configuration of the pipe scan section (10) is as follows.

[0056] Figure 2 is a detailed configuration diagram of the pipe scan section.

[0057] The pipe scan unit (10) includes, as shown in FIG. 2, a parameter setting unit (10a) that sets measurement parameters for measuring the degree of corrosion and water quality of a drinking water supply pipe, a measurement parameter optimization unit (10b) that optimizes the measurement parameters by using the results learned from the measurement results of the pipe corrosion measurement module (20) and the water quality measurement module (30), a B-scan result output unit (10c) that outputs a B-scan result for measuring the degree of corrosion of a pipe by using the difference in acoustic parameters due to the difference in thickness between the pipe and the part where corrosion has occurred, and an A-scan result output unit (10d) that outputs an A-scan result for measuring water quality by analyzing a signal reflected from an ultrasonic signal inside the pipe.

[0058] The multi-diagnosis method for simultaneously measuring the degree of corrosion and water quality of a drinking water supply pipe according to the present invention is specifically described as follows.

[0059] Figure 3 is a flow chart showing a multi-diagnosis method for simultaneously measuring the degree of corrosion and water quality of a drinking water supply pipe according to the present invention.

[0060] A multi-diagnosis method for simultaneously measuring the degree of corrosion and water quality of a drinking water supply pipe according to the present invention comprises a pipe scanning step (S301) of setting measurement parameters for measuring the degree of corrosion and water quality of a drinking water supply pipe, performing a pipe scan using a scanning acoustic microscope to output A-scan results and B-scan results, a pipe corrosion measurement step (S302) of measuring the degree of corrosion of a pipe by using the difference in acoustic parameters due to the difference in thickness between the pipe and the corroded portion using the B-scan results, an internal ultrasonic data acquisition step (S303) of receiving the A-scan results and acquiring internal ultrasonic data, and a water quality measurement step (S304) of classifying the concentration of iron oxide (Fe3O4) particles in water using IB (integrated backscattered) analysis and outputting a water quality measurement result based on the classification result.

[0061] Here, a measurement result learning step may be further included to provide a method for optimizing measurement parameters by learning the pipe corrosion measurement result of the pipe corrosion measurement step and the water quality measurement result of the water quality measurement step.

[0062] And pipe corrosion measurement and water quality measurement are performed simultaneously.

[0063] And the pipe scan step (S301) includes a parameter setting step for setting measurement parameters for measuring the degree of corrosion and water quality of a drinking water supply pipe, a measurement parameter optimization step for optimizing the measurement parameters by using the results of learning the pipe corrosion measurement results and the water quality measurement results, a B-scan result output step for outputting a B-scan result for measuring the degree of corrosion of a pipe by using the difference in acoustic parameters due to the difference in thickness between the pipe and the part where corrosion occurred, and an A-scan result output step for outputting an A-scan result for measuring water quality by analyzing a signal reflected from an ultrasonic signal inside the pipe.

[0064] In the pipe corrosion measurement step (S302), one of the advantages of a scanning acoustic microscope is that it is possible to detect corrosion levels in the μm range using a single ultrasonic transducer.

[0065] The degree of pipe corrosion can be accurately detected by utilizing the difference in acoustic parameters between the pipe and the corroded area, and analyzed using a B-scan obtained from a scanning acoustic microscope.

[0066] In the internal ultrasonic data acquisition step (S303), when corrosion occurs in the pipe, the signal of iron oxide reflected from the internal ultrasonic signal of the pipe is analyzed by using the iron oxide (Fe3O4) particles that fall off from the corroded area.

[0067] One of the advantages of scanning acoustic microscopy is that it can acquire a large amount of data at once, so ultrasonic data inside the pipe is acquired using A-scan.

[0068] In the water quality measurement step (S304), IB analysis is performed using A-scan data. IB analysis is a method frequently used in ultrasonic signal analysis, and water quality can be measured by classifying the iron oxide concentration of water inside the pipe using this analysis.

[0069] The multi-diagnostic system and method for simultaneously measuring the degree of corrosion and water quality of a drinking water supply pipe according to the present invention described above enables simultaneous pipe corrosion inspection and water quality inspection using a scanning ultrasonic microscope. The thickness of the pipe is measured using a scanning ultrasonic microscope (SAM) to confirm the degree of corrosion, and the water quality is measured by classifying the concentration of iron oxide particles in water using integrated backscattered (IB) analysis, thereby overcoming the limitations of non-destructive inspection methods and enabling more accurate and reliable simultaneous pipe corrosion inspection and water quality inspection.

[0070] As described above, it will be understood that the present invention can be implemented in modified forms without departing from the essential characteristics of the present invention.

[0071] Therefore, the specified embodiments should be considered in an illustrative rather than a restrictive sense, and the scope of the present invention is indicated by the claims rather than the foregoing description, and all differences within the scope equivalent thereto should be construed as being included in the present invention.
