However, those skilled in the art should understand that the present disclosure can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present disclosure.

[0024] To make the objectives, technical solutions, and advantages of the present disclosure clearer, the following will be described through specific embodiments in conjunction with the accompanying drawings.

[0025] Please refer to Figure 1 , Figure 1 which is a schematic flowchart of a method for ultrasonic strength detection of building concrete provided by an embodiment of the present disclosure. The method includes:

[0026] S101: Determine the environmental parameters of the target device, where the target device is a device for transmitting and receiving ultrasonic signals.

[0027] In this embodiment, the target device refers to a device for transmitting and receiving ultrasonic signals, such as an ultrasonic transmitter and an ultrasonic receiver.

[0028] Detecting the strength of building concrete through ultrasonic waves is one of the important means for current concrete quality assessment. Through this non-destructive detection method, engineers can effectively monitor and evaluate the strength and integrity of concrete structures, thereby ensuring the safety and service life of the structures. Ultrasonic signals are severely affected by environmental temperature and the physical characteristics of the target device.

[0029] In this embodiment, by collecting, processing, and analyzing environmental parameters (environmental temperature), the impact on the propagation and reception of ultrasonic signals is evaluated, and the operating parameters of the target device are adjusted accordingly to ensure the accuracy and reliability of ultrasonic detection.

[0030] Environmental parameters have a significant impact on the propagation and reception of ultrasonic waves. Different environmental conditions will cause phenomena such as attenuation, scattering, and refraction of ultrasonic signals, thereby affecting the strength and quality of the signals. Among them, temperature is an important environmental parameter. Changes in temperature will cause changes in the physical characteristics of the medium. If the detection environment is in a high-temperature state, the propagation speed of ultrasonic waves will increase, which may affect the propagation time and energy distribution of ultrasonic waves in concrete. If there is a large amount of water vapor in the surrounding area, the energy of ultrasonic waves will be absorbed and scattered, thereby affecting the strength and characteristics of the finally received signals.

[0031] S102: Determine the signal strength of the first ultrasonic signal based on the environmental parameters, where the first ultrasonic signal is the ultrasonic signal transmitted by the target device.

[0032] In one embodiment of the present disclosure, determining the signal strength of the first ultrasonic signal based on environmental parameters includes:

[0033] Determining the signal strength of the first ultrasonic signal through a first formula;

[0034] The first formula is:

[0035]

[0036] Wherein, is expressed as the signal strength of the first ultrasonic signal, is expressed as the efficiency of the target device, is expressed as the power of the power supply of the target device, is expressed as the difference between the current temperature and the reference temperature of, is expressed as the attenuation factor related to temperature, is expressed as the attenuation coefficient of the ultrasonic signal in the concrete to be measured, is expressed as the propagation distance from the target device to the surface of the concrete to be measured, is expressed as the density of the concrete to be measured, is expressed as the influence coefficient of the roughness of the surface of the concrete to be measured on the reflection efficiency of the ultrasonic signal, is expressed as the roughness of the surface of the concrete to be measured.

[0037] In this embodiment, the first ultrasonic signal refers to the ultrasonic signal directly emitted by the target device before passing through any medium.

[0038] After determining the environmental parameters, the first ultrasonic signal is determined according to these parameters. The setting of the signal strength needs to comprehensively consider the influence of the environment on the propagation of ultrasonic waves to ensure that the signal can penetrate the concrete to be measured and generate a reflected signal with sufficient strength. The selection of the signal strength should not only ensure that the signal can penetrate the concrete, but also avoid being too strong, which may cause signal distortion or damage to the receiving device.

[0039] In this embodiment, the signal strength of the first ultrasonic signal is determined through the first formula, and the efficiency of the target device is a coefficient related to the target device, indicating the efficiency of the target device in converting the power of the power supply into ultrasonic energy. Different devices may have different efficiencies. is the power of the power supply used by the target device when emitting ultrasonic waves. The greater the power of the power supply, the greater the signal strength of the emitted ultrasonic signal.

[0040] Indicates the influence of temperature on the signal strength of the ultrasonic signal, wherein, is expressed as the difference between the current temperature and the reference temperature of, Denoted as the temperature-related attenuation factor, as the temperature changes, the propagation speed and attenuation degree of ultrasonic waves in the air also change, thus affecting the signal strength. The influence of the surface roughness of the concrete on the reflection efficiency of the ultrasonic signal is considered. Among them, is the influence coefficient of the surface roughness on the reflection efficiency, is the surface roughness of the concrete. The surface roughness will affect the reflection and scattering of the ultrasonic signal, thus affecting the received signal strength.

[0041] Exemplarily, assume that we want to detect a concrete wall with a thickness of 2 cm. The efficiency of the target device is 0.8, the power supply power is 100 W, the reference temperature is 25 °C, the current temperature is 35 °C, the temperature-related attenuation factor is 0.02, the attenuation coefficient of the ultrasonic signal in the concrete to be measured is 0.05 per centimeter, the propagation distance from the target device to the surface of the concrete to be measured is 10 cm, the density of the concrete to be measured is 2500 kg / m³, the influence coefficient of the surface roughness of the concrete on the reflection efficiency of the ultrasonic signal is 0.03, and the surface roughness of the concrete is 0.05. Then substitute the above values into the first formula to determine the signal strength of the first ultrasonic signal.

[0042] In practical applications, the intensity of the first ultrasonic signal can be accurately set according to specific environmental parameters and concrete characteristics to ensure effective detection of the concrete strength and avoid problems caused by over-strong or over-weak signals. For example, if the calculated signal strength is insufficient, it may be necessary to adjust the power supply power of the device or replace the target device with higher efficiency; if the signal strength is too large, it may be necessary to reduce the power supply power or add some attenuation devices to protect the receiving device.

[0043] In this embodiment, the first formula accurately calculates the signal strength of the first ultrasonic signal by comprehensively considering multiple factors such as the efficiency of the target device, the power supply power, the environmental temperature, the attenuation of ultrasonic waves in the concrete, and the surface roughness of the concrete. It can improve the accuracy and reliability of ultrasonic detection, especially under complex environmental conditions.

[0044] S103: Analyze the strength of the concrete to be measured based on the second ultrasonic signal, where the second ultrasonic signal is the reflected signal of the first ultrasonic signal after passing through the concrete to be measured.

[0045] In an embodiment of the present disclosure, analyzing the strength of the concrete to be measured based on the second ultrasonic signal includes:

[0046] Preprocessing the second ultrasonic signal to obtain a fourth ultrasonic signal;

[0047] Analyzing the strength of the concrete to be measured based on the fourth ultrasonic signal.

[0048] In this embodiment, when the first ultrasonic signal encounters the concrete to be measured, part of the energy will be absorbed by the concrete, part of the energy will penetrate the concrete and continue to propagate, and the remaining part will be reflected back by the concrete surface or internal interfaces (such as the interface between aggregate and cement paste, cracks, etc.) to form a second ultrasonic signal (reflection signal). This reflection signal is received and recorded by the target device.

[0049] As the reflection signal of the first ultrasonic signal after passing through the concrete to be measured, the second ultrasonic signal carries information about the internal structure and characteristics of the concrete. However, during the actual acquisition process, the second ultrasonic signal will be interfered and affected by various factors, resulting in signal noise, distortion or other abnormalities. Therefore, it is necessary to preprocess the second ultrasonic signal to improve the signal quality and provide a more accurate and reliable basis for subsequent strength analysis. The preprocessing process may include the following operations:

[0050] Filtering: Removing high-frequency or low-frequency noise components to make the signal smoother and clearer.

[0051] Amplification or attenuation: Adjusting the amplitude of the signal to highlight important features or bring it into a suitable analysis range.

[0052] Removing outliers: Identifying and removing obvious abnormal data points caused by external sudden interference or equipment failures. The fourth ultrasonic signal obtained through preprocessing can truly reflect the internal situation of the concrete. Analyzing the strength of the concrete to be measured based on the fourth ultrasonic signal.

[0053] In this embodiment, the thickness of the concrete and the general situation of the internal structure can be inferred by calculating the time difference from the emission to the reception of the fourth ultrasonic signal and the amplitude of the fourth ultrasonic signal.

[0054] If the propagation time of the fourth ultrasonic signal is significantly shorter than expected, and the amplitude is large and the waveform is regular, it indicates that the strength of the concrete to be measured is very high; on the contrary, if the propagation time is long, the amplitude is small and the waveform is disordered, it means that the concrete strength is insufficient or there are quality problems.

[0055] It can be concluded from the above that in this embodiment, the environmental parameters of the target device that emits and receives ultrasonic signals are detected and determined to evaluate their influence on the ultrasonic propagation characteristics. Subsequently, based on these environmental parameters, the signal intensity of the first ultrasonic signal is accurately set to ensure that the signal can effectively penetrate the concrete to be tested while avoiding signal distortion or equipment damage caused by excessive signal strength. When the first ultrasonic signal encounters the concrete, part of the energy is reflected back to form the second ultrasonic signal. Finally, the strength of the concrete is analyzed through the second ultrasonic signal. Through this non-destructive testing process, the mechanical properties of the concrete can be accurately evaluated, providing reliable guarantees for the safety and durability of the building structure.

[0056] In one embodiment of the present disclosure, analyzing the strength of the concrete to be tested based on the second ultrasonic signal includes:

[0057] Determining the target test area of the concrete to be tested;

[0058] Analyzing the strength of the concrete to be tested based on the second ultrasonic signal in the target test area.

[0059] In one embodiment of the present disclosure, determining the target test area of the concrete to be tested includes:

[0060] Determining the target test area of the concrete to be tested based on the third ultrasonic signal, and using the third ultrasonic signal in the target test area as the second ultrasonic signal;

[0061] The third ultrasonic signal is the reflected signal of the first ultrasonic signal after passing through the concrete to be tested.

[0062] In one embodiment of the present disclosure, determining the target test area of the concrete to be tested based on the third ultrasonic signal includes:

[0063] Obtaining the signal intensity of the third ultrasonic signal, and determining the area of the concrete to be tested corresponding to the signal intensity greater than the first signal intensity as the target test area.

[0064] In the inspection of large-area concrete walls, due to the diffusion and attenuation characteristics of ultrasonic waves, the directly emitted first ultrasonic signal (initial ultrasonic wave) often cannot evenly cover the entire wall, and the signal intensity weakens with the increase of distance. Therefore, the intensity of the reflected third ultrasonic signal (i.e., the ultrasonic wave reflected after passing through the concrete) will also be affected accordingly. To accurately evaluate the strength of the concrete, an effective target test area needs to be determined, where the intensity of the reflected ultrasonic signal is strong enough to reflect the true strength characteristics of the concrete.

[0065] In this embodiment, a first signal strength is set as a threshold value. This threshold value can be calculated based on experience, experimental data, or a specific algorithm, and is used to distinguish valid reflected signals from invalid or weak reflected signals. By obtaining the signal strength of the third ultrasonic signal and comparing it with the first signal strength, the target test area can be determined. That is to say, only when the signal strength of the reflected ultrasonic signal is greater than or equal to the first signal strength, the concrete strength information of this area is considered valid, and thus this area is determined as the target test area.

[0066] Exemplarily, assume that we want to detect a concrete wall surface that is 20 meters long and 10 meters high. The coverage area of the first ultrasonic signal emitted by the target device on the concrete wall surface is a circular area with a radius of 2 meters, and the ultrasonic signal strength at the center position is the strongest, gradually weakening towards the edge. The set first signal strength is 80 units. During the detection, starting from the upper left corner of the wall surface, each time the target device is vertically aligned with the wall surface to emit the first ultrasonic signal. When a certain position is detected, the signal strength of the third ultrasonic signal obtained is 70 units, which is less than the first signal strength of 80 units, then this area is not determined as the target test area. Continue to detect other positions. At another location, the signal strength of the third ultrasonic signal obtained is 90 units, which is greater than the first signal strength of 80 units. Then, a circular area with a radius of 2 meters centered at this position is determined as the target test area. During the entire wall surface detection process, repeat the above operations, only paying attention to the areas where the reflected ultrasonic signal strength is greater than or equal to 80 units, and using the third ultrasonic signals in these areas as the second ultrasonic signals to analyze the strength of the concrete to be measured. Finally, through the analysis of the second ultrasonic signals in multiple target test areas, comprehensively evaluate whether the strength of the front concrete wall surface meets the requirements.

[0067] It can be concluded from the above that in this embodiment, by setting the signal strength threshold and determining the target test area based on the strength of the reflected ultrasonic signal (the third ultrasonic signal), the accuracy and efficiency of the strength detection of large-area concrete wall surfaces are effectively improved. It ensures that only the areas with strong enough signal strength are included in the analysis scope, so as to be able to more truly reflect the strength characteristics of the concrete wall surface and avoid the interference of weak reflected signals on the evaluation results.

[0068] In an embodiment of the present disclosure, analyzing the strength of the concrete to be measured based on the fourth ultrasonic signal includes:

[0069] Analyzing the strength of the concrete to be measured through the second formula;

[0070] The second formula is:

[0071]

[0072] Wherein, is expressed as the strength of the concrete to be measured, is expressed as the propagation time of the fourth ultrasonic signal, is expressed as the reference propagation time of the fourth ultrasonic signal, is expressed as the peak power of the fourth ultrasonic signal, is expressed as the reference peak power of the fourth ultrasonic signal, is expressed as the intensity of the fourth ultrasonic signal, is expressed as the reference intensity of the fourth ultrasonic signal, 、 and are all expressed as adjustment coefficients.

[0073] In this embodiment, the strength of the concrete to be measured can be analyzed through the second formula. The propagation time ratio takes into account the change in the propagation speed of ultrasonic waves in concrete. The faster the speed (i.e., the shorter the propagation time), the denser and stronger the concrete. The reference propagation time can be measured in concrete with known strength or under standard conditions. The peak power ratio reflects the energy loss situation of the ultrasonic signal during propagation in concrete. The smaller the energy loss (i.e., the higher the peak power), the less absorption and scattering of ultrasonic waves by the concrete, and the more uniform the internal structure. The intensity logarithm term takes into account the change in the intensity of the ultrasonic signal. The higher the intensity, the smaller the obstacle encountered by the ultrasonic wave during propagation in the concrete, and the better the quality of the concrete. The adjustment coefficients 、 and are used to make appropriate weight adjustments and calibrations for the influence of various parameters to adapt to different detection conditions and concrete types. Among them, is expressed as the adjustment coefficient of the propagation time ratio , is expressed as the adjustment coefficient of the peak power ratio , is expressed as the adjustment coefficient of the intensity logarithm term .

[0074] The adjustment coefficients 、 and can be determined through a large amount of experimental data and practical experience. Conduct a series of ultrasonic detection experiments on concrete samples with known strength. In these experiments, collect the propagation time 、peak power 、intensity Parameters such as these. Then, using statistical analysis methods such as regression analysis, fit the known strengths of these samples to the various ultrasonic parameters obtained through experiments. During the fitting process, continuously adjust , and values so that the calculated strength value is as close as possible to the actual known strength of the sample. Through comprehensive analysis and repeated verification of multiple situations, finally determine the , and values that can more accurately evaluate the concrete strength under specific detection conditions.

[0075] Exemplarily, assume that the strength of the concrete pier of a newly built bridge is to be detected. During the detection, the following relevant parameters are obtained:

[0076] The propagation time of the fourth ultrasonic signal is 45 microseconds, and the reference propagation time is 50 microseconds.

[0077] The peak power of the fourth ultrasonic signal is 75 watts, and the reference peak power is 65 watts.

[0078] The intensity of the fourth ultrasonic signal is 110 units, and the reference intensity is 90 units.

[0079] Adjustment coefficient After a large number of previous experiments and data analysis, it is determined to be 0.7; is 0.5; is 15.

[0080] Substitute these values into the second formula, and after calculation, obtain the value, thereby evaluating whether the strength of the pier concrete meets the design requirements.

[0081] It can be concluded from the above that in this embodiment, by accurately measuring the propagation time, peak power, and intensity of the fourth ultrasonic signal in the concrete to be measured and comparing and calculating with the reference data, the strength of the concrete to be measured can be evaluated efficiently and accurately. This not only improves the accuracy and reliability of the detection, but also provides strong technical support for the quality control and safety assessment of concrete structures, ensuring the overall quality and safety of the engineering construction.
