Commonly, image acquisition devices are used to monitor the surface of roads and bridges in real time. The main body of roads and bridges is mostly reinforced concrete structure. There is a certain correlation between internal damage to reinforced concrete structures and external image information. However, relying solely on external image information cannot guarantee the accuracy of road and bridge monitoring information, resulting in unreliable damage monitoring results.

[0011] This application provides an intelligent monitoring method and system for road and bridge damage, which solves the technical problem of low accuracy in road and bridge damage detection information, leading to unreliable damage monitoring results. It achieves the technical effect of intelligently optimizing road and bridge detection schemes and improving the accuracy of damage monitoring results by combining material structural characteristics.

[0012] Example 1 like Figure 1 As shown, this application provides an intelligent monitoring method for road and bridge damage, wherein the method is applied to an intelligent monitoring system, the intelligent monitoring system being communicatively connected to an image acquisition device, a rebound hammer, and an ultrasonic pulse device, and the method includes: S100: Obtain material and structural information of roads and bridges through the intelligent monitoring system; S200: Based on the image acquisition device and combined with the material structure information, acquire image information of roads and bridges, and obtain feature image information; Specifically, the intelligent monitoring system integrates an information storage module, such as a register, which records relevant data about the road and bridge. Information is retrieved and extracted using identifiers to obtain the material structure information of the road and bridge. This material structure information includes structural diagrams of the road and bridge's construction process, steel reinforcement skeleton diagrams, steel types, concrete, and other relevant material structure information. The image acquisition device can be a camera or other imaging device. Based on the material structure characteristics, the main load-bearing locations are determined, and these locations are monitored closely. Image information of the road and bridge is collected, and characteristic image information is obtained to provide data support for subsequent data processing and ensure the effectiveness of the characteristic image information.

[0013] S300: The surface rebound value of the road bridge is obtained by performing a verification test using the rebound hammer. S400: Using the ultrasonic pulse device, a penetration method is employed to conduct verification tests and obtain the performance and structural parameter information of the road and bridge. Specifically, the rebound hammer has an embedded operation panel. The rebound value is read from the pointer on the panel. Simply put, by pressing and holding the rebound hammer, the pointer on the panel is read. Alternatively, by locking the rebound hammer with a latch, the pointer on the panel is locked, allowing direct reading of the surface rebound value of the road and bridge. The ultrasonic pulse device includes an ultrasonic transmitter and an ultrasonic receiver. It uses the penetration method for verification testing and evaluates parameters by receiving ultrasonic waves through reflection and reception to obtain the performance and structural parameter information of the road and bridge. This performance and structural parameter information includes the material performance parameters and other relevant characteristic parameters of the road and bridge, providing reliable data support for subsequent data analysis.

[0014] To elaborate further, during the entire process of operating the rebound hammer for verification testing, attention should be paid to the posture of holding the rebound hammer. One hand should hold the middle part of the rebound hammer to straighten it; the other hand should hold the tail of the instrument to apply pressure to the instrument and also to assist in straightening it, so as to avoid unreliable surface rebound values ​​due to improper operation.

[0015] Furthermore, step S400 includes: S410: Using the ultrasonic pulse device, a verification test is performed using the penetration method to obtain the ultrasonic received wave; S420: Based on the ultrasonic received wave, determine the sound propagation speed, the amplitude of the first wave, the frequency of the cosine wave component, and the waveform; S430: The internal performance of the road and bridge is verified and evaluated by using the sound propagation speed, first wave amplitude, cosine wave component frequency, and waveform, and the performance and structural parameter information of the road and bridge is obtained.

[0016] Specifically, the ultrasonic pulse device includes an ultrasonic transmitter and an ultrasonic receiver. Using the ultrasonic pulse device, a penetration method is employed for verification testing to obtain the received ultrasonic wave. Based on the received ultrasonic wave, the transmitted and received waveforms are compared to determine the sound propagation speed, initial wave amplitude, cosine wave component frequency, and waveform. Using the sound propagation speed, initial wave amplitude, cosine wave component frequency, and waveform, the internal performance of the road and bridge is verified and evaluated, obtaining the performance and structural parameter information of the road and bridge.

[0017] To further explain, the rebound hammer can perform surface rebound tests on the surface of the road and bridge, with a test depth generally not exceeding 3 cm. The ultrasonic pulse device can test the internal parameter information of the road and bridge, ensuring the comprehensiveness and effectiveness of the structural parameter information of the road and bridge.

[0018] S500: By comprehensively evaluating the surface rebound value and the performance structural parameter information, the structural strength information of the road and bridge is obtained; Furthermore, such as Figure 2 As shown, step S500 includes: S510: Based on the carbonation depth measuring instrument, test and obtain the carbonation depth information of the road bridge; S520: By comprehensively evaluating the performance structural parameter information and the surface rebound value, the rebound performance index information of the road bridge is obtained; S530: Based on the carbonation depth information and the resilience performance index information, obtain the structural strength information of the road and bridge through the concrete strength conversion table.

[0019] Specifically, the structural strength information of the road and bridge is obtained by comprehensively evaluating the surface rebound value and the performance structural parameters through cluster analysis. The cluster analysis method can include k-means, K-medoids, and other clustering algorithms. The carbonation depth measuring instrument can be used to detect the carbonation depth of the concrete structure. Concrete carbonation is a form of chemical corrosion. Based on the carbonation depth measuring instrument, the carbonation depth information of the road and bridge is obtained. The carbonation depth at different locations of the road and bridge may vary and needs to be determined through actual test results; no limiting statement is made here. The structural performance parameters and the surface rebound value are comprehensively evaluated, and the index parameter feature extraction training is performed using the backpropagation algorithm to obtain the rebound performance index information of the road and bridge. Based on the carbonation depth information and the rebound performance index information, the structural strength information of the road and bridge is obtained through a concrete strength conversion table, effectively ensuring the reliability of the structural strength information.

[0020] To further explain, the horizontal axis of the concrete strength conversion table represents the average carbonation depth of the concrete surface in that block, and the vertical axis represents the average rebound value of the concrete surface in that block. The average strength value of the concrete in that block is converted using these two axes. Generally, to ensure the reliability of the results during strength calculation, it is necessary to test the destructive force on the structure. However, destructive testing can lead to structural damage. Therefore, the preferred method is to use the concrete strength conversion table. Further refinement based on actual data is not detailed here.

[0021] S600: Determine whether the structural strength information has been verified. If it has, conduct a dynamic test on the road bridge to obtain dynamic test verification information. S700: Based on the feature image information and the dynamic test verification information, obtain the test verification feature results, which are used to verify and monitor road and bridge damage.

[0022] Furthermore, such as Figure 3 As shown, to determine whether the structural strength information has passed verification, step S600 further includes: S610: Determine whether the structural strength information has been verified. If not, combine the material structure information and use the pull-out method to avoid the load-bearing position to obtain the concrete pull-out force data of the road and bridge. S620: Based on the concrete pull-out force data, determine whether additional measurement correction is needed, and obtain the calculated value of the concrete pull-out force; S630: Based on the calculated value of the concrete pull-out force, determine the damage and defect information of the road and bridge accordingly; S640: Determine whether the damage defect information exceeds the limit. If it does not exceed the limit, repair the anchors and concrete in the concrete to obtain road and bridge damage information.

[0023] Specifically, the dynamic tests include, but are not limited to, vibration tests and fatigue tests. A comprehensive analysis of the stability and maximum load of the road and bridge is conducted to determine structural strength standards. These standards are then used to determine whether the structural strength information has passed verification. If it has, a dynamic test is performed on the road and bridge to obtain dynamic test verification information. Based on the feature image information and the dynamic test verification information, test verification feature results are obtained. These test verification feature results are used to verify and monitor road and bridge damage, effectively ensuring the rationality and effectiveness of the dynamic test verification information, ensuring that the test verification feature results can fully reflect road and bridge damage information, and improving the stability of the test verification feature results.

[0024] Specifically, the structural strength information is verified based on the structural strength standard. If it fails, the concrete pull-out force data for the road and bridge is obtained using a pull-out method, avoiding load-bearing locations, based on the material structure information. The accuracy of the concrete strength information obtained by the pull-out method is higher than that obtained by using a concrete strength conversion table, but the pull-out method causes some damage to the road and bridge structure. Based on the concrete pull-out force data, it is determined whether additional measurement correction is needed. If the pull-out force data is stable, it means that no additional measurement correction is needed. The specific determination is made comprehensively based on actual data information to obtain the concrete pull-out force data. The concrete pull-out force is calculated to determine the concrete strength information of the road and bridge, and correspondingly, the damage and defect information of the road and bridge is determined. It is then determined whether the damage and defect information exceeds the limit. If it does not exceed the limit, the structural damage caused by the pull-out test is repaired. The anchors and concrete in the concrete of the road and bridge are repaired, and the road and bridge damage information is obtained. If the structural strength information cannot meet the structural strength standard, the pull-out method can improve the accuracy of the strength data, provide reliable data reference for road and bridge damage repair, and ensure the stability of the road and bridge damage information.

[0025] Furthermore, determining whether the damage / defect information exceeds the limit, step S640 includes: S641: Determine whether the damage and defect information exceeds the limit. If it does, combine the material structure information and use the core drilling method to collect the test core sample of the road and bridge, avoiding the load-bearing position. S642: Based on multiple core samples mentioned above, perform compressive strength tests to obtain splitting strength and internal defect information; S643: By combining the splitting strength and the internal defect information, the damage defect information is optimized to obtain accurate damage information for roads and bridges, and the detected samples are repaired.

[0026] Specifically, using a gravity sensing testing device, the historical maximum load of the road and bridge is measured. This historical maximum load is not greater than the maximum load. A comprehensive analysis of the road and bridge's stability and the maximum load is performed to determine the structural strength. Based on the historical maximum load, a damage defect threshold is determined. This threshold is used to determine if the damage defect information exceeds the limit. If it does, core drilling is used in conjunction with material structure information. The accuracy of concrete strength information measured by core drilling is higher than that measured by pull-out method, but core drilling causes some damage to the road and bridge structure. Generally, the damage caused by core drilling to the road and bridge structure is greater than that caused by pull-out method. Therefore, load-bearing locations should be avoided. Core samples are collected from roads and bridges. Generally, the number of core samples is no less than 6. The actual number of core samples needs to be analyzed in conjunction with the structural volume of the road and bridge. Based on multiple core samples, compressive strength tests are performed to obtain multiple sets of splitting tensile strength and internal defect information. Combined with the sampling location of the core samples, data optimization and adjustment are performed to obtain splitting tensile strength and internal defect information. Through the splitting tensile strength and internal defect information, the damage defect information is optimized to obtain accurate damage information of the road and bridge. The detected samples are then repaired. By using the core drilling method, the accuracy of the strength data can be further improved, providing reliable data reference for road and bridge damage repair and further ensuring the accuracy of the accurate damage information.

[0027] Furthermore, a dynamic test is conducted on the road bridge to obtain dynamic test verification information. Step S600 includes: S610: Conduct vibration tests on the road and bridge using an accelerometer to verify and evaluate the vibration damage of the road and bridge, and obtain vibration test information; S620: Using the detection and maintenance log information of the intelligent monitoring system, perform fatigue analysis on the road and bridge, verify and evaluate the impact damage of the road and bridge, and obtain fatigue verification information; S630: The vibration test information and the fatigue verification information are weighted and fused to obtain dynamic test verification information.

[0028] Specifically, vibration tests are conducted on the road and bridge using accelerometers to verify and evaluate vibration damage. The magnitude of the acceleration from the accelerometer can be adjusted based on actual test conditions to obtain vibration test information. The inspection and maintenance log information is the data corresponding to the maintenance records of the road and bridge. This data is extracted through the integrated information storage module within the intelligent monitoring system to obtain the inspection and maintenance log information. Fatigue analysis is then performed on the road and bridge using this log information to verify and evaluate impact damage and obtain fatigue verification information. Finally, the vibration test information and the fatigue verification information are weighted and fused to obtain dynamic test verification information, ensuring the reliability of this information.

[0029] In summary, the intelligent monitoring method and system for road and bridge damage provided in this application have the following technical advantages: This application provides an intelligent monitoring method and system for road and bridge damage. It utilizes an intelligent monitoring system to acquire material and structural information of roads and bridges, image acquisition devices to collect image information and obtain feature image information, a rebound hammer to obtain surface rebound values, and ultrasonic pulse devices to perform penetration tests to obtain performance and structural parameter information. By combining the surface rebound value with these performance and structural parameter information, the structural strength information of the road and bridge is obtained. Once the structural strength information is verified, a dynamic test is conducted to obtain dynamic test verification information. Combined with this dynamic test verification information, test verification feature results are obtained, thus verifying and monitoring road and bridge damage. This application achieves the technical effect of intelligently optimizing road and bridge detection schemes and improving the accuracy of damage monitoring results by combining material and structural characteristics.

[0030] Since the structural strength information verification fails, the pull-out method is used in conjunction with the material structure information to obtain the concrete pull-out force data of the road and bridge by avoiding the load-bearing position. If no additional measurement correction is required, the concrete pull-out force calculation value is obtained to determine the damage and defect information of the road and bridge. If the damage and defect information does not exceed the limit, the anchors in the concrete and the concrete are repaired to obtain the road and bridge damage information. When the structural strength information cannot meet the structural strength standard, the pull-out method can improve the accuracy of the strength data, provide reliable data reference for road and bridge damage repair, and ensure the stability of road and bridge damage information.

[0031] By employing vibration tests on roads and bridges using accelerometers to verify and assess vibration damage, and obtaining vibration test information, fatigue analysis is performed on roads and bridges using the detection and maintenance logs from an intelligent monitoring system. This verifies and assesses impact damage and obtains fatigue verification information. Furthermore, by combining the vibration test information with weighted fusion and allocation, dynamic test verification information is obtained, ensuring the reliability of the dynamic test verification information.
