However, it should be clear to those skilled in the art that the present disclosure may 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 obstructing the description of the present disclosure with unnecessary details.

[0013] In order to make the purpose, technical solutions and advantages of the present disclosure more clear, specific embodiments will be described below in conjunction with the accompanying drawings.

[0014] Please refer to Figure 1 , Figure 1 A schematic diagram of a method for ultrasonic strength testing of building concrete provided in an embodiment of the present disclosure, the method comprising: S101: Determine environmental parameters of a target device, where the target device is a device that transmits and receives ultrasonic signals.

[0015] 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.

[0016] Ultrasonic testing of the strength of building concrete is one of the important means of evaluating concrete quality. Through this non-destructive testing method, engineers can effectively monitor and evaluate the strength and integrity of concrete structures, thereby ensuring the safety and service life of the structure. Ultrasonic signals are severely affected by ambient temperature and the physical properties of the target device.

[0017] In this embodiment, environmental parameters (ambient temperature) are collected, processed and analyzed to evaluate their impact on the propagation and reception of ultrasonic signals, and the operating parameters of the target device are adjusted accordingly, thereby ensuring the accuracy and reliability of ultrasonic detection.

[0018] Environmental parameters have a significant impact on the propagation and reception of ultrasound. Different environmental conditions can cause attenuation, scattering, refraction and other phenomena of ultrasonic signals, which in turn affect the strength and quality of the signal. Among them, temperature is an important environmental parameter. Changes in temperature can cause changes in the physical properties of the medium. If the detection environment is at a high temperature, the propagation speed of ultrasound will increase, which may affect its propagation time and energy distribution in concrete. If there is a large amount of water vapor around, the energy of the ultrasound will be absorbed and scattered, which will affect the strength and characteristics of the final received signal.

[0019] S102: Determine a signal strength of a first ultrasonic signal based on an environmental parameter, where the first ultrasonic signal is an ultrasonic signal emitted by a target device.

[0020] In one embodiment of the present disclosure, determining the signal strength of the first ultrasonic signal based on the environmental parameter includes: Determine the signal strength of the first ultrasonic signal by using a first formula; The first formula is:

[0021] in, It is represented as the signal strength of the first ultrasonic signal, Expressed as the efficiency of the target device, Expressed as the power supply of the target device, Expressed as current temperature and reference temperature The difference, Expressed as a temperature-dependent attenuation factor, It is expressed as the attenuation coefficient of the ultrasonic signal in the concrete to be tested. It is expressed as the propagation distance from the target device to the concrete surface to be tested, Expressed as the density of the concrete to be tested, It is expressed as the influence coefficient of the roughness of the concrete surface to be tested on the reflection efficiency of the ultrasonic signal. Expressed as the roughness of the concrete surface to be tested.

[0022] In this embodiment, the first ultrasonic signal refers to an ultrasonic signal directly emitted by the target device before passing through any medium.

[0023] After determining the environmental parameters, the first ultrasonic signal is emitted according to these parameters. The setting of the signal strength needs to comprehensively consider the impact of the environment on ultrasonic propagation to ensure that the signal can penetrate the concrete to be tested and generate a reflection signal of sufficient strength. The selection of signal strength should ensure that the signal can penetrate the concrete, but also avoid being too strong to cause signal distortion or damage to the receiving equipment.

[0024] In this embodiment, the signal strength of the first ultrasonic signal is determined by the first formula, and the efficiency of the target device is Is a coefficient related to the target device, which indicates the efficiency of the target device in converting the mains power into ultrasonic energy. Different devices may have different efficiencies. It is the power used by the target device when emitting ultrasound. The greater the power, the greater the intensity of the emitted ultrasonic signal.

[0025] The effect of temperature on the ultrasonic signal intensity is shown, among which, Expressed as current temperature and reference temperature The difference, Expressed as a temperature-dependent attenuation factor, as the temperature changes, the propagation speed and attenuation of ultrasound in the air will also change, thus affecting the signal strength. The influence of concrete surface roughness on the reflection efficiency of ultrasonic signals is considered. is the influence coefficient of surface roughness on reflection efficiency, It is the roughness of the concrete surface. The surface roughness affects the reflection and scattering of ultrasonic signals, thus affecting the received signal strength.

[0026] For example, suppose we want to detect a concrete wall with a thickness of 2 cm. The efficiency of the target device is 0.8, power supply power 100W, reference temperature The current temperature is 25℃ At 35°C, the temperature-dependent attenuation factor is 0.02, the attenuation coefficient of the ultrasonic signal in the concrete to be tested is The propagation distance from the target device to the concrete surface to be tested is 0.05 per centimeter. is 10cm, the density of the concrete to be tested The influence coefficient of the roughness of the concrete surface on the ultrasonic signal reflection efficiency is 2500 kg / m3. is 0.03, the roughness of the concrete surface The above value is then substituted into the first formula to determine the signal strength of the first ultrasonic signal.

[0027] In practical applications, the strength of the first ultrasonic signal can be accurately set according to specific environmental parameters and concrete characteristics to ensure that the strength of the concrete can be effectively detected while avoiding problems caused by too strong or too weak signals. For example, if the calculated signal strength is insufficient, it may be necessary to adjust the power supply of the device or replace the target device with a more efficient one; if the signal strength is too high, it may be necessary to reduce the power supply or add some attenuation devices to protect the receiving device.

[0028] 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, the ambient temperature, the attenuation of the ultrasonic wave in the concrete, and the roughness of the concrete surface, etc. This can improve the accuracy and reliability of ultrasonic detection, especially under complex environmental conditions.

[0029] S103: Analyze the strength of the concrete to be tested based on the second ultrasonic signal, where the second ultrasonic signal is a reflection signal of the first ultrasonic signal after passing through the concrete to be tested.

[0030] In one embodiment of the present disclosure, analyzing the strength of the concrete to be tested based on the second ultrasonic signal includes: preprocessing the second ultrasonic signal to obtain a fourth ultrasonic signal; The strength of the concrete to be tested is analyzed based on the fourth ultrasonic signal.

[0031] In this embodiment, when the first ultrasonic signal encounters the concrete to be tested, 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 interface (such as the interface between aggregate and cement paste, cracks, etc.), forming a second ultrasonic signal (reflected signal). This reflected signal is received and recorded by the target device.

[0032] The second ultrasonic signal is the reflected signal of the first ultrasonic signal after passing through the concrete to be tested, and carries information about the internal structure and characteristics of the concrete. However, in the actual acquisition process, the second ultrasonic signal will be interfered and affected by various factors, resulting in noise, distortion or other abnormalities in the signal. 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 intensity analysis. The preprocessing process can include the following operations: Filtering: Remove high-frequency or low-frequency noise components to make the signal smoother and clearer.

[0033] Amplify or attenuate: Adjust the amplitude of a signal to emphasize important features or bring it within a suitable range for analysis.

[0034] Remove outliers: Identify and remove data points that are obviously abnormal due to sudden external interference or equipment failure. The fourth ultrasonic signal obtained after preprocessing can truly reflect the internal situation of the concrete. The strength of the concrete to be tested is analyzed based on the fourth ultrasonic signal.

[0035] 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.

[0036] If the propagation time of the fourth ultrasonic signal is significantly shorter than expected, and has a large amplitude and a regular waveform, it indicates that the strength of the concrete to be tested 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.

[0037] From the above, it can be concluded that this embodiment detects and determines the environmental parameters of the target device that transmits and receives ultrasonic signals to evaluate its impact on the ultrasonic propagation characteristics. Subsequently, based on these environmental parameters, the signal strength of the first ultrasonic signal is accurately set to ensure that the signal can effectively penetrate the concrete to be tested, while avoiding distortion or equipment damage caused by excessive signal strength. When the first ultrasonic signal encounters concrete, part of the energy is reflected back to form a second ultrasonic signal. Finally, the strength of the concrete is analyzed by the second ultrasonic signal. Through this non-destructive detection process, the mechanical properties of concrete can be accurately evaluated, providing reliable protection for the safety and durability of building structures.

[0038] In one embodiment of the present disclosure, analyzing the strength of the concrete to be tested based on the second ultrasonic signal includes: Determine the target test area of ​​the concrete to be tested; The strength of the concrete to be tested is analyzed based on the second ultrasonic signal of the target test area.

[0039] In one embodiment of the present disclosure, determining a target test area of ​​concrete to be tested includes: Determine a target test area of ​​the concrete to be tested based on the third ultrasonic signal, and use the third ultrasonic signal in the target test area as the second ultrasonic signal; The third ultrasonic signal is a reflection signal of the first ultrasonic signal after passing through the concrete to be tested.

[0040] In one embodiment of the present disclosure, determining a target test area of ​​the concrete to be tested based on the third ultrasonic signal includes: The signal strength of the third ultrasonic signal is obtained, and an area of ​​the concrete to be tested having a signal strength greater than that corresponding to the first signal strength is determined as a target test area.

[0041] In the detection of large-area concrete walls, due to the diffusion and attenuation characteristics of ultrasound, the first ultrasonic signal (initial ultrasonic wave) emitted directly often cannot evenly cover the entire wall surface, and the signal strength decreases with increasing distance. Therefore, the intensity of the reflected third ultrasonic signal (that is, the ultrasonic wave reflected after passing through the concrete) will also be affected accordingly. In order to accurately evaluate the strength of concrete, it is necessary to determine an effective target test area where the intensity of the reflected ultrasonic signal is strong enough to reflect the true strength characteristics of the concrete.

[0042] In this embodiment, a first signal strength is set as a threshold. This threshold can be calculated based on experience, experimental data or a specific algorithm to distinguish between valid reflection signals and invalid or weak reflection 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, 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 the area is considered valid, and therefore the area is determined as the target test area.

[0043] For example, suppose we want to detect a concrete wall that is 20 meters long and 10 meters high. The coverage range of the first ultrasonic signal emitted by the target device on the concrete wall is a circular area with a radius of 2 meters. The ultrasonic signal strength at the center is the strongest and gradually weakens toward the edge. The set first signal strength is 80 units. During the detection, starting from the upper left corner of the wall, the target device is vertically aimed at the wall to emit the first ultrasonic signal each time. When a certain position is detected, the third ultrasonic signal strength obtained is 70 units, which is less than the first signal strength of 80 units, then the area is not determined as the target test area. Continue to detect other positions. The third ultrasonic signal strength obtained at another place is 90 units, which is greater than the first signal strength of 80 units. Then the circular area with a radius of 2 meters centered on this position is determined as the target test area. During the entire wall detection process, repeat the above operation, only focus on the areas where the reflected ultrasonic signal strength is greater than or equal to 80 units, and use the third ultrasonic signals in these areas as the second ultrasonic signals to analyze the strength of the concrete to be tested. Finally, by analyzing the second ultrasonic signals of multiple target test areas, a comprehensive assessment is made as to whether the strength of the front concrete wall meets the requirements.

[0044] It can be concluded from the above that this embodiment effectively improves the accuracy and efficiency of large-area concrete wall strength detection by setting a signal strength threshold and determining the target test area based on the strength of the reflected ultrasonic signal (third ultrasonic signal). It ensures that only areas with sufficiently strong signal strength are included in the analysis range, thereby being able to more truly reflect the strength characteristics of the concrete wall and avoiding interference of weak reflected signals on the evaluation results.

[0045] In one embodiment of the present disclosure, analyzing the strength of the concrete to be tested based on the fourth ultrasonic signal includes: Analyze the strength of the concrete to be tested by the second formula; The second formula is:

[0046] in, It is expressed as the strength of the concrete to be tested. is represented as the propagation time of the fourth ultrasonic signal, is represented as the reference propagation time of the fourth ultrasonic signal, is represented by the peak power of the fourth ultrasonic signal, is represented as the reference peak power of the fourth ultrasonic signal, is represented by the intensity of the fourth ultrasonic signal, is represented as the reference intensity of the fourth ultrasonic signal, , and Both are expressed as adjustment coefficients.

[0047] In this embodiment, the strength of the concrete to be tested can be analyzed by the second formula. Taking into account the change in the propagation speed of ultrasound in concrete, the faster the speed (i.e. the shorter the propagation time), the denser and stronger the concrete. Reference propagation time It can be measured in concrete of known strength or under standard conditions. It reflects the energy loss of ultrasonic signals during propagation in concrete. The smaller the energy loss (i.e., the higher the peak power), the less the concrete absorbs and scatters the ultrasonic waves, and the more uniform the internal structure. The change in ultrasonic signal strength is taken into account. The higher the strength, the less resistance the ultrasonic wave encounters when propagating in concrete, and the better the concrete quality. Adjustment coefficient , and It is used to properly adjust and calibrate the influence of various parameters to adapt to different test conditions and concrete types. Expressed as the propagation time ratio The adjustment factor, Peak power ratio The adjustment factor, Expressed as the intensity logarithm The adjustment factor.

[0048] Adjustment factor , and The determination can be made through a large amount of experimental data and practical experience. A series of ultrasonic testing experiments are conducted on concrete samples with known strength. In these experiments, the propagation time of the fourth ultrasonic signal corresponding to a large number of concrete samples with different strengths is collected. , Peak Power ,strength Then, statistical analysis methods, such as regression analysis, are used to fit the known intensities of these samples with the various ultrasonic parameters obtained through experiments. , and , so that the calculated intensity value Through comprehensive analysis and repeated verification of various situations, we finally determined the most accurate method for evaluating the concrete strength under specific testing conditions. , and The value of .

[0049] For example, suppose a strength test is performed on a concrete pier of a newly built bridge. During the test, the relevant parameters obtained are as follows: The propagation time of the fourth ultrasonic signal The reference propagation time is 45 microseconds is 50 microseconds.

[0050] The peak power of the fourth ultrasonic signal 75 watts, reference peak power is 65 watts.

[0051] The strength of the fourth ultrasonic signal The reference intensity is 110 units. It is 90 units.

[0052] Adjustment factor After a lot of early experiments and data analysis, it was determined to be 0.7; is 0.5; is 15.

[0053] Substituting these values ​​into the second formula, we get value, thereby evaluating whether the strength of the pier concrete meets the design requirements.

[0054] It can be concluded from the above that this embodiment can efficiently and accurately evaluate the strength of the concrete to be tested by accurately measuring the propagation time, peak power and intensity of the fourth ultrasonic signal in the concrete to be tested, and performing comparative calculations with reference data. 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 engineering construction.
