[0102] Embodiment 1

[0103] Figure 1The flowchart of a method for arranging an ultrasonic thickness sensor provided by an embodiment of the present invention. This embodiment is applicable to the situation of arranging an ultrasonic thickness sensor in a pipeline. This method can be executed by the ultrasonic thickness sensor arranging device in the embodiment of the present invention, and the device can be implemented in a software and / or hardware manner, such as Figure 1 As shown, the method specifically includes the following steps:

[0104] S110, obtain the temperature parameters and geometric parameters of the pipeline to be detected.

[0105] In this embodiment, the temperature parameters of the pipeline to be detected include at least one of the operating temperature, design temperature, ambient temperature, internal temperature of the pipeline, actual temperature limit, and standard temperature limit. The operating temperature can be collected by a temperature sensor, and the operating temperature includes the operating time and the pipeline temperature corresponding to the operating time. The design temperature is the normal working temperature set during pipeline design and can be obtained by querying the pipeline design document or operation manual. The ambient temperature is the real-time temperature at the location of the pipeline. The ambient temperature can be collected by a temperature sensor arranged at the location where the pipeline is located.

[0106] In this embodiment, the geometric parameters include at least one of the wall thickness, diameter, and radius of curvature.

[0107] In this embodiment, the way to obtain the temperature parameters of the pipeline to be detected can be: obtain the operating temperature, design temperature, and ambient temperature of the pipeline to be detected; determine the internal temperature of the pipeline to be detected according to the operating temperature, design temperature, and ambient temperature of the pipeline to be detected. Determine the actual temperature limit according to the internal temperature of the pipeline. Determine the standard temperature limit according to the sound velocity-temperature linear graph.

[0108] In this embodiment, the way to obtain the geometric parameters of the pipeline to be detected can be: determine the wall thickness of the pipeline to be detected according to the sound velocity-temperature linear graph, the internal temperature of the pipeline, the standard temperature limit, and the real-time detection time. The way to obtain the geometric parameters of the pipeline to be detected can also be: directly measure the diameter and radius of curvature of the pipeline to be detected.

[0109] Optionally, the temperature parameters include: the internal temperature of the pipeline, the actual temperature limit, and the standard temperature limit;

[0110] Obtaining the temperature parameters of the pipeline to be detected includes:

[0111] Obtain the operating temperature, design temperature, and ambient temperature of the pipeline to be detected.

[0112] In this embodiment, the operating temperature includes: the operating time and the pipeline temperature corresponding to the operating time. The design temperature is the normal operating temperature set during pipeline design. The ambient temperature is the real-time temperature at the location where the pipeline is located.

[0113] Determine the internal temperature of the pipeline to be detected according to the operating temperature, design temperature and ambient temperature of the pipeline to be detected.

[0114] In this embodiment, the method for determining the internal temperature of the pipeline to be detected according to the operating temperature, design temperature and ambient temperature of the pipeline to be detected may be: draw a temperature-time curve according to the operating temperature of the pipeline to be detected; determine the initial temperature of the pipeline to be detected according to the temperature-time curve; determine the internal temperature of the pipeline to be detected according to the initial temperature, design temperature and ambient temperature of the pipeline to be detected.

[0115] Determine the actual temperature limit according to the internal temperature of the pipeline and the temperature limit adjustment amount.

[0116] In this embodiment, the setting of the temperature limit adjustment amount is related to factors such as the material of the pipeline and / or historical data, etc. The temperature limit adjustment amount can be a fixed value or a dynamic value that changes according to specific conditions.

[0117] In this embodiment, the method for determining the actual temperature limit according to the internal temperature of the pipeline and the temperature limit adjustment amount may be: obtain the maximum value of the internal temperature of the pipeline within a time period, and use the sum of the maximum value of the internal temperature of the pipeline and the temperature limit adjustment amount as the actual temperature limit.

[0118] In this embodiment, set the temperature limit adjustment amount according to factors such as the material of the pipeline or / and historical data, etc. The temperature limit adjustment amount can be a fixed value or a dynamic value that changes according to specific conditions. Within a certain time period, find the maximum value of the internal temperature of the pipeline. This maximum value represents the highest temperature that the pipeline may reach under normal operating conditions. Use the sum of the maximum value of the internal temperature of the pipeline and the set temperature limit adjustment amount as the actual temperature limit of the pipeline to be detected. This temperature limit will be used in the subsequent temperature monitoring and alarm system. When the internal temperature of the pipeline exceeds this limit, the system will issue an alarm to prompt relevant personnel to take corresponding measures. Through the above steps, the temperature limit of the pipeline to be detected can be effectively determined to ensure that the pipeline operates within a safe temperature range and avoid safety accidents caused by excessive temperature.

[0119] In this embodiment, by setting the temperature limit adjustment amount, the detection accuracy and flexibility can be improved.

[0120] Use the temperature intercept of the sound velocity-temperature linear graph as the standard temperature limit.

[0121] In this embodiment, the sound velocity - temperature linear graph is used to characterize the corresponding relationship between temperature and sound velocity.

[0122] In this embodiment, the method for obtaining the sound velocity - temperature linear graph is as follows: Use a sample ultrasonic thickness sensor to measure a pipeline sample (the actual wall thickness of the pipeline sample is known), record the ultrasonic propagation time at different temperatures and the sample detection time at different temperatures, and obtain the ultrasonic sound velocity at different temperatures according to the ultrasonic propagation time at different temperatures and the actual wall thickness of the pipeline sample; draw the sound velocity - temperature linear graph based on the ultrasonic sound velocity at different temperatures. It should be noted that the detection range of the sample ultrasonic thickness sensor covers all specifications of the pipeline to be detected.

[0123] Optionally, determining the internal temperature of the pipeline to be detected according to the operating temperature, design temperature, and ambient temperature of the pipeline to be detected includes:

[0124] Draw a temperature - time curve according to the operating temperature of the pipeline to be detected.

[0125] In this embodiment, the operating temperature of the pipeline to be detected is collected in real - time, and a temperature - time curve is drawn according to the operating temperature.

[0126] Determine the initial temperature of the pipeline to be detected according to the temperature - time curve.

[0127] In this embodiment, the initial temperature is the temperature of the pipeline when it is not affected by the environment.

[0128] In this embodiment, pre - process the temperature - time curve. The pre - processing includes delimiting a time interval and determining sampling time points; set the function expression of the temperature - time curve graph as f(t); determine the initial temperature of the pipeline to be detected corresponding to the sampling time points according to the sampling time points and the time interval;

[0129] The initial temperature is calculated according to the following formula:

[0130]

[0131] where, W t is the initial temperature of the pipeline to be detected at the sampling time point t, and Δt is the time interval.

[0132] In this embodiment, the intervals on the time axis of the temperature-time curve are determined, and the intervals are related to the acquisition frequency or specific requirements of the experimental design. For example, if the acquisition frequency is once per second, the time interval can be set to 1 second or longer, depending on the volatility of the data and the required analysis accuracy. Key time points on the temperature-time curve are selected for sampling. The key time points can basically represent the overall trend of the temperature change. The functional expression of the temperature-time curve graph is set as f(t), where t represents time and f(t) represents the temperature at time t. According to the selected sampling time points and time intervals, by integrating the time within half of the time interval before and after the sampling time point and determining the ratio of the integral value to the time interval, this ratio is determined as the initial temperature of the pipeline to be detected at time t.

[0133] The technical solution provided in this embodiment improves the pertinence and effectiveness of data analysis by delimiting the time interval and determining the sampling time points, and can accurately capture the temperature change trend. Setting the functional expression of the temperature-time curve graph facilitates mathematical modeling and computer processing, and improves the data processing efficiency. The initial temperature is obtained through integral calculation, increasing the detection accuracy. The above technical solution can adapt to data with different acquisition frequencies and volatility, improving the applicability and flexibility. It helps to better understand the temperature change law inside the pipeline and provides a basis for subsequent temperature control and optimization.

[0134] It can be understood that the functional expression in this embodiment can be processed and fitted by a computer to obtain an expression that matches the temperature-time curve graph. By using mathematical modeling software or statistical and numerical analysis libraries in programming languages, curve fitting analysis can be performed on experimental data. For example, the least squares method can be used to determine the best fit curve, which can minimize the difference between the actual data points and the fit curve.

[0135] According to the initial temperature, design temperature, and ambient temperature of the pipeline to be detected, determine the internal temperature of the pipeline to be detected.

[0136] In this embodiment, the method for determining the internal temperature of the pipeline to be detected according to the initial temperature, design temperature, and ambient temperature of the pipeline to be detected can be: taking the product of the difference between the ambient temperature and the design temperature and the ambient temperature influence coefficient as the correction temperature; taking the sum of the initial temperature of the pipeline to be detected and the correction temperature as the internal temperature of the pipeline to be detected.

[0137] Optionally, determining the internal temperature of the pipeline to be detected according to the initial temperature, design temperature, and ambient temperature of the pipeline to be detected includes:

[0138] Take the product of the difference between the ambient temperature and the design temperature and the ambient temperature influence coefficient as the corrected temperature.

[0139] In this embodiment, if the ambient temperature is greater than the design temperature, the corrected temperature is positive; if the ambient temperature is less than the design temperature, the corrected temperature is negative.

[0140] Take the sum of the initial temperature of the pipeline to be detected and the corrected temperature as the internal temperature of the pipeline to be detected.

[0141] In this embodiment, the internal temperature of the pipeline is determined according to the following formula;

[0142]

[0143] Where, W n is the internal temperature of the pipeline, a is the ambient temperature influence coefficient, W h is the ambient temperature, W s is the design temperature, W t is the initial temperature.

[0144] In this embodiment, the initial temperature is corrected according to the ambient temperature to obtain a more accurate internal temperature of the pipeline. In a specific example, obtain the design temperature of the hot oil transported by the pipeline. The design temperature is the normal operating temperature set during pipeline design and can be obtained by querying the pipeline design document or operation manual. Measure the current ambient temperature, that is, the real-time temperature at the location of the pipeline. Calculate the temperature difference between the ambient temperature and the design temperature. The influence of the ambient temperature on the internal temperature of the pipeline can be determined according to the temperature difference between the ambient temperature and the design temperature. Determine the corrected temperature according to the temperature difference. The corrected temperature is calculated based on the difference between the ambient temperature and the design temperature and is used to adjust the initial temperature. Compare the ambient temperature with the design temperature. If the ambient temperature is higher than the design temperature, it means that the influence of the ambient temperature on the internal temperature of the pipeline is positive, that is, the ambient temperature will increase the internal temperature of the pipeline. If the ambient temperature is greater than the design temperature, the corrected temperature is positive, and the initial temperature is corrected positively. This means that the initial temperature needs to be added with the corrected temperature to obtain a more accurate internal temperature of the pipeline. If the ambient temperature is less than the design temperature, the corrected temperature is negative, and the initial temperature is corrected negatively according to the corrected temperature to obtain a more accurate internal temperature of the pipeline. Through the above steps, the corrected internal temperature of the pipeline can be obtained, so as to more accurately evaluate the operating condition of the pipeline and the transmission efficiency of the hot oil.

[0145] In this embodiment, the initial temperature is corrected by the ambient temperature of the pipeline to be detected in real time to obtain the internal temperature of the pipeline to be detected, which can enhance the accuracy of temperature detection and ensure the safety and efficiency of the pipeline. By comparing and correcting the ambient temperature with the designed temperature, the stability and safety of the pipeline under variable environments are improved.

[0146] Optionally, the geometric parameters of the pipeline to be detected include: the wall thickness of the pipeline to be detected;

[0147] Obtain the geometric parameters of the pipeline to be detected, including:

[0148] Take the slope of the sound speed-temperature linear graph as the sound speed influence coefficient.

[0149] In this embodiment, the sound speed-temperature linear graph can be obtained in the following way: Use a sample ultrasonic thickness sensor to measure a pipeline sample (the actual wall thickness of the pipeline sample is known), record the ultrasonic propagation time at different temperatures and the sample detection time at different temperatures, and obtain the ultrasonic sound speed at different temperatures according to the ultrasonic propagation time at different temperatures and the actual wall thickness of the pipeline sample; Draw a sound speed-temperature linear graph based on the ultrasonic sound speed at different temperatures. It should be noted that the detection range of the sample ultrasonic thickness sensor covers all specifications of the pipeline to be detected.

[0150] In a specific example, determine the sample wall thickness of the pipeline sample; Use a sample ultrasonic thickness sensor to measure a pipeline sample (the actual wall thickness of the pipeline sample is known), record the ultrasonic propagation time at different temperatures and the sample detection time at different temperatures, and determine the ultrasonic sound speed of the sample ultrasonic thickness sensor according to the sample wall thickness, the sample detection time and the ultrasonic propagation time at different temperatures; Draw a sound speed-temperature linear graph based on the ultrasonic sound speed. Determine the slope and temperature intercept of the sound speed-temperature linear graph, set the slope as the influence coefficient of temperature on the ultrasonic sound speed, and set the temperature intercept as the standard temperature limit.

[0151] In this embodiment, to determine the influence coefficient of temperature on the ultrasonic sound velocity, it is first necessary to determine the sample wall thickness of the pipeline sample: measure the actual wall thickness of the pipeline sample to ensure the accuracy of the data. Use an ultrasonic thickness sensor to measure the pipeline sample and record the ultrasonic propagation time at different temperatures. According to the ultrasonic propagation speed formula in the material, calculate the ultrasonic sound velocity at different temperatures. Plot the sound velocity data points at different temperatures on a coordinate graph, with the horizontal axis being temperature and the vertical axis being sound velocity. Through linear regression analysis, fit the best linear relationship curve. Determine the slope and temperature intercept of the sound velocity-temperature linear graph: the slope represents the change in sound velocity when the temperature changes by 1 degree, that is, the influence coefficient of temperature on the ultrasonic sound velocity. The temperature intercept represents the reference value of the sound velocity at the standard temperature (usually room temperature). Set the slope and temperature intercept: set the slope as the influence coefficient of temperature on the ultrasonic sound velocity to describe the specific influence of temperature change on the sound velocity. Set the temperature intercept as the standard temperature limit value to determine the reference value of the sound velocity at the standard temperature. Through the above steps, the influence coefficient of temperature on the ultrasonic sound velocity and the reference value of the sound velocity at the standard temperature can be obtained. These data are of great significance for the calibration and temperature compensation of ultrasonic measurement equipment.

[0152] It can be seen that this technical solution helps to more accurately evaluate the propagation characteristics of ultrasonic waves in the pipeline by determining the sample wall thickness of the pipeline sample. Determine the sample ultrasonic sound velocity of the sample ultrasonic thickness sensor through the sample wall thickness and detection time, providing a data basis for the subsequent study of the sound velocity-temperature relationship. Draw a sound velocity-temperature linear graph to visually show the law of sound velocity changing with temperature, which helps to understand and predict the influence of temperature on the ultrasonic sound velocity. Determine the slope and temperature intercept of the sound velocity-temperature linear graph, and set the slope as the influence coefficient of temperature on the ultrasonic sound velocity, providing theoretical support for practical applications. Set the temperature intercept as the standard temperature limit value, which helps to control the influence of temperature on the ultrasonic sound velocity during actual operation and ensure the safe operation of the pipeline.

[0153] Obtain the ultrasonic sound velocity corresponding to the standard temperature limit value in the sound velocity-temperature linear graph.

[0154] In this embodiment, take the ordinate corresponding to the standard temperature limit value in the sound velocity-temperature linear graph as the ultrasonic sound velocity corresponding to the standard temperature limit value.

[0155] Determine the real-time ultrasonic sound velocity according to the ultrasonic sound velocity corresponding to the standard temperature limit value, the sound velocity influence coefficient, the internal temperature of the pipeline, and the standard temperature limit value.

[0156] In this embodiment, the real-time ultrasonic sound velocity is determined according to the following formula:

[0157] V s =V0 + b·(W n-W0);

[0158] Among them, V s is the real-time ultrasonic sound speed, V0 is the ultrasonic sound speed corresponding to the standard temperature limit, b is the sound speed influence coefficient, and W n is the internal temperature of the pipeline, and W0 is the standard temperature limit.

[0159] In this embodiment, the real-time ultrasonic sound speed is: the wave speed corresponding to the internal temperature of the pipeline.

[0160] Determine the wall thickness of the pipeline to be detected according to the detection time corresponding to the internal temperature of the pipeline and the real-time ultrasonic sound speed.

[0161] In this embodiment, the detection time is the real-time time detected by the sensor when the temperature is the internal temperature of the pipeline, that is, the ultrasonic round-trip time.

[0162] In this embodiment, it is necessary to understand the relationship between the sound speed influence coefficient and the ultrasonic sound speed. The sound speed influence coefficient is usually related to factors such as the properties of the material and the temperature, which will affect the propagation speed of ultrasonic waves in the material. Through experiments or theoretical calculations, correction formulas or correction coefficients for ultrasonic sound speed under different conditions can be obtained. According to the current environmental conditions and material characteristics, using these formulas or coefficients, the real-time ultrasonic sound speed can be calculated. Determine the wall thickness of the pipeline to be detected according to the real-time ultrasonic sound speed and the real-time detection time. The basic principle of ultrasonic thickness measurement is to determine the thickness of the material by measuring the time for ultrasonic waves to propagate in the material. Specifically, ultrasonic waves are emitted from the sensor to the surface of the material and then reflected back to the sensor, and the total round-trip time is recorded. Since the propagation speed of ultrasonic waves in the material is known, the thickness of the material can be calculated by the following formula: wall thickness = (ultrasonic propagation speed × round-trip time) / 2; where the round-trip time refers to the total time for ultrasonic waves to be emitted from the sensor to the surface of the material and then reflected back to the sensor. Since the propagation speed of ultrasonic waves in the material changes in real time, it is necessary to use the real-time ultrasonic sound speed to calculate the wall thickness to ensure the accuracy of the measurement results. Through the above steps, the wall thickness of the pipeline to be detected can be monitored and determined in real time using an ultrasonic thickness sensor, so as to evaluate and monitor the health status of the pipeline.

[0163] In this embodiment, the method for determining the wall thickness of the pipeline to be detected according to the detection time corresponding to the internal temperature of the pipeline and the real-time ultrasonic sound speed can be: taking the ratio of the product of the detection time corresponding to the internal temperature of the pipeline and the real-time ultrasonic sound speed to the first value as the wall thickness of the pipeline to be detected.

[0164] It can be seen that this technical solution ensures that the measurement result is consistent with the actual wall thickness by improving the accuracy of the ultrasonic thickness measurement technology, realizes the real-time monitoring of the wall thickness of the pipeline to be detected, improves the detection efficiency, reduces the human measurement error, improves the reliability of the detection data, optimizes the use effect of the ultrasonic sensor, and prolongs the service life.

[0165] Optionally, determining the wall thickness of the pipeline to be detected according to the detection time corresponding to the internal temperature of the pipeline and the real-time ultrasonic sound velocity includes:

[0166] Taking the ratio of the product of the detection time corresponding to the internal temperature of the pipeline and the real-time ultrasonic sound velocity to the first value as the wall thickness of the pipeline to be detected.

[0167] In this embodiment, the first value is a preset value. For example, the first value can be 2.

[0168] In this embodiment, the wall thickness of the pipeline to be detected is determined according to the following formula:

[0169]

[0170] where H is the wall thickness of the pipeline to be detected, V s is the real-time ultrasonic sound velocity, and T s is the real-time detection time.

[0171] S120. Determine the target ultrasonic thickness sensor according to the temperature parameter and geometric parameter of the pipeline to be detected.

[0172] In this embodiment, the temperature parameter includes: the actual temperature limit value, and the geometric parameter includes: the wall thickness and the diameter.

[0173] In this embodiment, the method for determining the target ultrasonic thickness sensor according to the temperature parameter and geometric parameter of the pipeline to be detected may be as follows: Obtain the specification parameters of each sensor in the initial set of ultrasonic thickness sensors, compare the temperature limit, wall thickness, and diameter with the specification parameters of each sensor, and select the sensor that matches as the target ultrasonic thickness sensor. The specification parameters include at least one of the working temperature range, size, shape, measurement accuracy, and response time. The method for determining the target ultrasonic thickness sensor according to the temperature parameter and geometric parameter of the pipeline to be detected may also be as follows: Obtain the initial set of ultrasonic thickness sensors; screen the initial set of ultrasonic thickness sensors based on the actual temperature limit of the pipeline to be detected to obtain a first set of ultrasonic thickness sensors, where the working temperature ranges of the sensors in the first set of ultrasonic thickness sensors all cover the actual temperature limit of the pipeline; screen the first set of ultrasonic thickness sensors based on the wall thickness of the pipeline to be detected to obtain a second set of ultrasonic thickness sensors, where the measurement upper limit of the sensors in the second set of ultrasonic thickness sensors is higher than the wall thickness of the pipeline to be detected, and the measurement lower limit of the sensors is lower than the wall thickness of the pipeline to be detected; screen the second set of ultrasonic thickness sensors based on the diameter of the pipeline to be detected to obtain at least one target ultrasonic thickness sensor.

[0174] In this embodiment, compare the temperature limit, wall thickness, and diameter of the pipeline to be detected with the specification parameters of the sensors available in the market, and screen out the target ultrasonic thickness sensor that can withstand the highest temperature and is suitable for the wall thickness and diameter.

[0175] In a specific example, compare the temperature limit, wall thickness, and diameter of the pipeline to be detected with the specification parameters of the sensors available in the market, and according to the comparison results, select the sensor that most conforms to the pipeline parameters. Ensure that the temperature range of the selected sensor covers the highest working temperature of the pipeline, and the size of the sensor is suitable for the wall thickness and diameter of the pipeline.

[0176] Optionally, the geometric parameters of the pipeline to be detected include: the wall thickness and diameter of the pipeline to be detected;

[0177] Determining the target ultrasonic thickness sensor according to the temperature parameter and geometric parameter of the pipeline to be detected includes:

[0178] Obtain the initial set of ultrasonic thickness sensors.

[0179] In this embodiment, the initial set of ultrasonic thickness sensors includes multiple ultrasonic thickness sensors. The specifications of each ultrasonic thickness sensor are different.

[0180] Screen the initial ultrasonic thickness sensor set based on the actual temperature limit of the pipeline to be detected, and obtain the first ultrasonic thickness sensor set.

[0181] In this embodiment, the operating temperature ranges of the sensors in the first ultrasonic thickness sensor set all cover the actual temperature limit of the pipeline.

[0182] Screen the first ultrasonic thickness sensor set based on the wall thickness of the pipeline to be detected, and obtain the second ultrasonic thickness sensor set.

[0183] In this embodiment, the measurement upper limit of the sensors in the second ultrasonic thickness sensor set is higher than the wall thickness of the pipeline to be detected, and the measurement lower limit of the sensors is lower than the wall thickness of the pipeline to be detected.

[0184] Determine the target sensor type according to the diameter of the pipeline to be detected.

[0185] In this embodiment, the target sensor types include: the first type, the second type, and the third type. The sensors of the first type are sensors with a small size and a probe shape. For example, ultrasonic thickness sensors with a micro probe or a needle probe, so as to be able to closely fit the pipeline surface and ensure the effective transmission of ultrasonic signals. The sensors of the first type have a higher frequency. Because when high-frequency ultrasonic waves propagate in a small-diameter pipeline, the energy is concentrated and the resolution is high, which can measure the wall thickness more accurately. However, the attenuation of high-frequency signals is relatively large, so it is necessary to consider comprehensively according to the pipeline material and the measurement range. For example, for small-diameter metal pipelines, sensors with a frequency of 5 MHz or higher can be selected. The sensors of the second type are conventional ultrasonic thickness sensors. They can be general-purpose sensors, so as to be flexibly set according to different pipeline materials, wall thicknesses, and measurement requirements. The sensors of the second type are sensors with a medium frequency (for example, 2 - 5 MHz), which can achieve a good balance between measurement accuracy and signal propagation distance. For the measurement of medium-diameter pipelines with high accuracy requirements, sensors with an accuracy of up to ±0.1 mm can be selected. The sensors of the third type are ultrasonic thickness sensors with a wide beam or a variable-angle probe. The sensors of the third type are sensors with signal enhancement and compensation functions.

[0186] In this embodiment, the method for determining the target sensor type according to the diameter of the pipeline to be detected may be: determining the type of the pipeline to be detected according to the diameter of the pipeline to be detected, and determining the target sensor type according to the type of the pipeline to be detected. The types of pipelines to be detected include: small-diameter pipelines, medium-diameter pipelines, and large-diameter pipelines. If the diameter of the pipeline to be detected is less than or equal to the second value, it is determined that the type of the pipeline to be detected is a small-diameter pipeline. If the diameter of the pipeline to be detected is greater than the second value and less than the third value, it is determined that the type of the pipeline to be detected is a medium-diameter pipeline. If the diameter of the pipeline to be detected is greater than the third value, it is determined that the type of the pipeline to be detected is a large-diameter pipeline. The sensor of the target sensor type in the second ultrasonic thickness sensor set is used as the target ultrasonic thickness sensor.

[0187] Optionally, determining the target sensor type according to the diameter of the pipeline to be detected includes:

[0188] If the diameter of the pipeline to be detected is less than or equal to the second value, it is determined that the target sensor type is the first type.

[0189] In this embodiment, the second value is a preset value. For example, the second value may be 100 mm.

[0190] In this embodiment, the sensor of the first type is a sensor with a small size and a probe shape. The sensor of the first type has a higher frequency.

[0191] If the diameter of the pipeline to be detected is greater than the second value and less than the third value, it is determined that the target sensor type is the second type.

[0192] In this embodiment, the third value is a preset value, and the third value is greater than the second value. For example, if the second value is set to 100 mm, the third value may be set to 500 mm.

[0193] In this embodiment, the third value is greater than the second value.

[0194] In this embodiment, the sensor of the second type is a conventional ultrasonic thickness sensor, and the sensor of the second type is a sensor with a medium frequency.

[0195] If the diameter of the pipeline to be detected is greater than the third value, it is determined that the target sensor type is the third type.

[0196] In this embodiment, the sensor of the third type is an ultrasonic thickness sensor with a wide beam or a variable angle probe. The sensor of the third type is a sensor with signal enhancement and compensation functions.

[0197] In this embodiment, if the diameter of the pipeline to be detected is greater than the third value, it is determined that the pipeline to be detected is a large-diameter pipeline. Since the measurement of a large-diameter pipeline needs to consider the probe angle and beam characteristics of the sensor to ensure that the ultrasonic wave can cover the entire pipeline wall thickness and reflect well on the inner surface of the pipeline. An ultrasonic thickness sensor with a wide beam or variable angle probe can be selected to obtain more accurate measurement results on a large-diameter pipeline. Since the ultrasonic signal may be attenuated significantly in a large-diameter pipeline, a sensor with signal enhancement and compensation functions needs to be selected to improve the reliability of the measurement. Some high-end ultrasonic thickness sensors have functions such as automatic gain control and sound speed compensation, which can meet the measurement requirements of large-diameter pipelines.

[0198] In this embodiment, when screening the sensor, a sensor with more accurate detection accuracy is selected, and the detection range is narrowed according to the parameters of the pipeline to be detected.

[0199] S130. Determine the installation elements of the target ultrasonic thickness sensor according to the geometric parameters of the pipeline to be detected.

[0200] In this embodiment, the geometric parameters include: the radius of curvature, and the installation elements include: the installation position and / or the installation method.

[0201] In this embodiment, according to the radius of curvature of the pipeline to be detected, determine the installation position and installation method of the target ultrasonic thickness sensor.

[0202] It should be noted that the installation position and installation method of the sensor should ensure that the sensor can accurately measure the temperature of the pipeline surface, and at the same time avoid affecting the performance of the sensor or causing damage due to the bending of the pipeline.

[0203] In this embodiment, plan the installation position of the sensor according to the radius of curvature of the pipeline. If there is a bent part in the pipeline, it is necessary to ensure that the sensor can fit the pipeline surface while maintaining good heat conduction. During the layout process, special installation brackets or fixtures may be needed to fix the sensor.

[0204] In this embodiment, the geometric parameters of the pipeline to be detected include at least one of the wall thickness, diameter, radius of curvature, and material of the pipeline to be detected.

[0205] In this embodiment, the installation elements include: the installation position and / or the installation method. Select a suitable installation method according to the actual situation of the pipeline and the installation space. Common installation methods include magnetic adsorption type, adhesive type, flange installation, etc. For situations that require frequent movement or temporary measurement, magnetic adsorption installation is more convenient; for pipelines with long-term fixed monitoring, adhesive type or flange installation is more reliable.

[0206] Optionally, the installation elements include: installation location and installation method, and the geometric parameters of the pipeline to be detected include: the radius of curvature of the pipeline to be detected;

[0207] Determine the installation elements of the target ultrasonic thickness sensor according to the geometric parameters of the pipeline to be detected, including:

[0208] If the radius of curvature of the pipeline to be detected is greater than or equal to the first radius of curvature threshold, determine the installation location of the target ultrasonic thickness sensor as the top of the pipeline, and the installation methods include: magnetic adsorption installation or bolt fixed installation.

[0209] In this embodiment, the first radius of curvature threshold is a preset value, for example, it can be 1 meter.

[0210] In this embodiment, if the radius of curvature of the pipeline to be detected is greater than or equal to the first radius of curvature threshold, it means that the pipeline to be detected is a pipeline with a large radius of curvature. The sensor is installed in the flat area at the top or bottom of the pipeline, and a stable measurement reference can be obtained, which is convenient for installation and maintenance. If the pipeline has a thermal insulation layer, a position where the thermal insulation layer is easy to disassemble and restore can be selected to reduce damage to the thermal insulation structure. Avoid areas such as the welds, valves, and pipe fittings connections of the pipeline, where stress concentration, material inhomogeneity, or surface unevenness may exist, which will affect the measurement accuracy.

[0211] In this embodiment, magnetic adsorption installation: suitable for ferromagnetic pipelines, easy to install, and the position can be adjusted at any time. Using a strong magnetic chuck, it can firmly adsorb on the pipeline surface, and the sensor can be flexibly moved when performing multi-point measurements. Bolt fixed installation: For occasions that require long-term fixation and high precision requirements, an installation seat can be welded on the pipeline, and the sensor is fixed by bolts to ensure a stable installation and reduce vibration interference.

[0212] If the radius of curvature of the pipeline to be detected is less than the first radius of curvature threshold and greater than the second radius of curvature threshold, determine the installation location of the target ultrasonic thickness sensor as the side of the pipeline, and the installation methods include: adhesive installation or hoop installation, and the first radius of curvature threshold is greater than the second radius of curvature threshold.

[0213] In this embodiment, the second radius of curvature threshold can be a preset value less than the first radius of curvature threshold. For example, when the first radius of curvature threshold is 1 meter, the second radius of curvature threshold is set to 0.3 meter.

[0214] In this embodiment, if the radius of curvature of the pipeline to be detected is less than the first radius-of-curvature threshold and greater than the second radius-of-curvature threshold, it indicates that the pipeline to be detected is a pipeline with a medium radius of curvature. It is preferably installed at a position about 45° from the horizontal direction on the side of the pipeline, which can not only ensure good contact between the sensor and the pipeline surface, but also make the ultrasonic propagation path relatively stable, reducing the refraction and reflection errors caused by the pipeline curvature. For pipelines with tracing, installation near the tracing device should be avoided to prevent heat from affecting the sensor performance and measurement accuracy.

[0215] In this embodiment, for adhesive installation: when the pipeline surface is flat, a special adhesive can be used to paste the sensor on the pipeline. This installation method is simple and can ensure close fitting between the sensor and the pipeline, which is applicable to non-ferromagnetic pipelines or situations where magnetic adsorption installation is not convenient. For hoop installation: the sensor is fixed on the pipeline through a customized hoop, and the hoop can be adjusted according to the radius of curvature of the pipeline, which can adapt to the changes in different pipe diameters, and the installation and disassembly are relatively convenient.

[0216] If the radius of curvature of the pipeline to be detected is less than the second radius-of-curvature threshold, the installation position of the target ultrasonic thickness sensor is determined to be the straight section area or the end of the pipeline, and the installation methods include: customized fixture installation or strap installation.

[0217] In this embodiment, if the radius of curvature of the pipeline to be detected is less than the second radius-of-curvature threshold, it indicates that the pipeline to be detected is a pipeline with a small radius of curvature. The straight section of the pipeline is selected. If there is no obvious straight section, an area with relatively gentle curvature change can be selected on the pipeline circumference to ensure that the sensor probe can fit the pipeline surface as much as possible. Due to the limited space of pipelines with a small radius of curvature, the installation position should be convenient for operation and cable connection to avoid interference between the sensor and other surrounding devices or pipelines.

[0218] In this embodiment, for customized fixture installation: due to the particularity of pipelines with a small radius of curvature, special fixtures are usually required to install the sensor. The fixture should be designed to closely surround the pipeline and can be adjusted through an adjustment mechanism to adapt to different radii of curvature, ensuring good contact between the sensor and the pipeline surface. For strap installation: an elastic strap is used to fix the sensor on the pipeline. This method can automatically adjust the fitting degree according to the curvature of the pipeline and is applicable to some pipelines with a small radius of curvature that require high installation convenience and diverse pipeline materials, but attention should be paid to the tightening degree of the strap to avoid affecting the measurement accuracy of the sensor.

[0219] In a specific example, the operating temperature of the pipeline to be detected is collected in real time, a temperature-time curve is generated based on the operating temperature, and the temperature-time curve is analyzed to determine the initial temperature of the pipeline to be detected. The ambient temperature of the pipeline to be detected is obtained in real time, and the initial temperature is corrected according to the ambient temperature to obtain the internal temperature of the pipeline to be detected. The temperature limit value of the pipeline to be detected is determined according to the internal temperature of the pipeline. A sample ultrasonic thickness sensor is used to detect pipeline samples at different temperatures, the sample detection time is obtained, and the influence coefficient of temperature on the sound velocity of ultrasonic waves is determined according to the sample detection time. The sample ultrasonic thickness sensor is used to detect the pipeline to be detected, the real-time detection time is obtained, and based on the sound velocity influence coefficient, the wall thickness of the pipeline to be detected is determined according to the real-time detection time. The diameter and curvature radius of the pipeline to be detected are measured, the type of the sensor is selected according to the temperature limit value, wall thickness and diameter, and the layout elements of the selected sensor are determined according to the curvature radius.

[0220] The technical solution provided in this embodiment can accurately determine the initial temperature of the pipeline to be detected by collecting and analyzing the operating temperature data in real time. And by correcting the influence of the ambient temperature, the internal temperature of the pipeline to be detected is accurately calculated to ensure the accuracy of the detection data. The sample ultrasonic thickness sensor is used to measure the pipeline sample, the ultrasonic wave propagation time at different temperatures and the sample detection time at different temperatures are recorded, and according to the ultrasonic wave propagation time at different temperatures and the actual wall thickness of the pipeline sample, the ultrasonic sound velocity at different temperatures is obtained; a sound velocity-temperature linear graph is drawn according to the ultrasonic sound velocity at different temperatures, and the sound velocity influence coefficient is determined according to the sound velocity-temperature linear graph to improve the detection accuracy. Based on the sound velocity influence coefficient and the real-time detection time, the wall thickness of the pipeline to be detected is accurately measured. The appropriate type of sensor is selected according to the temperature limit value, wall thickness and diameter, and the layout elements of the sensor are determined according to the pipeline curvature radius to optimize the sensor layout and improve the detection efficiency.

[0221] It should be noted that after the layout is completed, the installation and testing of the sensor are carried out to ensure that the sensor can work normally and the measurement data is accurate and reliable.

[0222] The technical solution of this embodiment can ensure that the sensor specifications match the conditions of the pipeline to be detected, improve the accuracy and reliability of thickness monitoring; optimize the sensor layout scheme, reduce the monitoring blind area, and enhance the comprehensiveness of thickness detection; simplify the sensor selection and layout process, and reduce the work difficulty and cost.

[0223] The technical solution of this embodiment is to obtain the temperature parameters and geometric parameters of the pipeline to be detected; determine the target ultrasonic thickness sensor according to the temperature parameters and geometric parameters of the pipeline to be detected; and determine the installation elements of the target ultrasonic thickness sensor according to the geometric parameters of the pipeline to be detected, which can ensure that the selected sensor is suitable for the thickness monitoring requirements of the pipeline to be detected and can be correctly arranged on the pipeline to be detected to achieve effective thickness monitoring.

[0230] The technical solution of this embodiment can accurately determine the initial temperature and internal temperature of the pipeline by collecting the operating temperature and ambient temperature of the pipeline to be detected in real time and analyzing the temperature-time curve. By using these temperature data to correct the influence coefficient of the ultrasonic sound velocity, the measurement accuracy of the ultrasonic thickness sensor is greatly improved. By detecting pipeline samples under different temperature conditions, obtaining the sample detection time, and determining the influence coefficient of temperature on the ultrasonic sound velocity, it is ensured that the pipeline wall thickness can be reliably measured in different temperature environments. This method reduces the errors caused by temperature changes and improves the reliability of the detection results. The diameter and curvature radius of the pipeline to be detected are considered, and the appropriate type of sensor is selected according to these parameters, and the sensor is arranged according to the curvature radius. This enables the sensor to adapt to pipelines of different diameters and shapes, enhancing the versatility and applicability of the system. In addition, the sensor arranged based on the technical solution provided in this embodiment monitors the thickness of the pipeline to be detected, can timely detect changes in the pipeline wall thickness, provide immediate data support, facilitate the adoption of preventive maintenance measures, and avoid potential safety hazards. Through precise sensor arrangement and efficient data acquisition methods, unnecessary sensor usage and maintenance costs are reduced. At the same time, the measurement accuracy is improved, and the repair and replacement costs caused by misjudgment are reduced. Generally speaking, the standardized arrangement method of the ultrasonic thickness sensor proposed by the present invention not only improves the measurement accuracy and stability, but also reduces the complexity of sensor design and use, and has broad application prospects and important practical significance.
