[0002] As a vital component of infrastructure, bridges play a critical role in modern society. However, as bridge service life increases, structural health monitoring and damage detection become increasingly important. Traditional bridge monitoring methods typically use sensors to measure parameters such as stress, displacement, and vibration, and then analyze the data to assess the structural health of the bridge.

[0003] However, traditional methods have some limitations and challenges: (1) Traditional sensors can usually only measure physical parameters at local locations and cannot achieve comprehensive monitoring of the entire bridge structure; (2) Traditional methods are interfered by noise and environmental factors, resulting in limited measurement sensitivity and accuracy, especially for monitoring small structural changes; (3) Because traditional methods require offline data collection and complex analysis, real-time monitoring of the health status of the bridge becomes difficult.

[0051] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute a separate or alternative embodiment that is mutually exclusive of other embodiments.

[0052] The embodiments of the present invention provide a bridge monitoring method, system, structural condition monitoring device and storage medium, which are described below respectively.

[0053] FIG1 is a flow chart of an embodiment of a bridge monitoring method provided by the present invention. As shown in FIG1 , the bridge monitoring method includes:

[0054] S101, obtaining at least one quantum bit pair in a quantum entangled state;

[0055] S102, establishing a coupling relationship between the quantum bit pair state of at least one quantum bit pair and the physical parameters of the bridge;

[0056] S103. Monitor the quantum bit pair state of at least one quantum bit pair, and determine the structural state of the bridge based on the quantum bit pair state and the coupling relationship.

[0057] Compared with the prior art, the bridge monitoring method provided by the embodiment of the present invention first obtains at least one quantum bit pair in a quantum entangled state, and then monitors the structural state of the bridge based on the at least one quantum bit pair. The special correlation of the quantum entangled state means that the state change of one quantum bit will immediately affect the state of another quantum bit, which is not affected by distance. Therefore, it is possible to monitor the entire range of the bridge and bridges with larger spans, and the monitoring results are more comprehensive. Furthermore, the embodiment of the present invention utilizes the non-classical properties of quantum bits to capture tiny structural changes and achieve high-sensitivity monitoring of the bridge. Furthermore, since the quantum bit pair state of the quantum bit pair can be obtained in real time, real-time monitoring of the bridge can be achieved.

[0058] It should be noted that the bridge monitoring method proposed in the embodiment of the present invention can also be applied to monitor the structural status of structures such as roads and tunnels.

[0059] In a specific embodiment of the present invention, the coupling relationship in step S102 can be the relationship between the energy splitting of the qubit and physical parameters such as bridge stress, bridge temperature, and bridge vibration. It can also be the relationship between the transition frequency of the qubit and physical parameters such as bridge stress, bridge temperature, and bridge vibration. In other words, by measuring the energy splitting or transition frequency of the qubit, physical changes such as bridge stress can be determined through the coupling relationship, thereby enabling monitoring of the bridge structure's condition.

[0060] It should also be noted that: in order to achieve real-time monitoring of the structural status of the bridge, the specific method of monitoring the quantum bit pair state of at least one quantum bit pair in step S103 is: equip a special quantum measurement device for real-time monitoring of the quantum bits. The quantum measurement device should have the characteristics of high precision and high speed to capture changes in the quantum bit state.

[0061] It's important to note that after acquiring the qubit pairs, they need to be fixed to the bridge to monitor the bridge's structural status. Specifically, at least one qubit is fixed to the bridge's target location using a sensor. The sensor can be a superconducting coil or a micro-nanomechanical structure.

[0062] It should be noted that: since quantum bits are sensitive to external noise and environmental influences, in order to avoid the impact of external noise and environment on the monitoring results, in some embodiments of the present invention, when fixing at least one quantum bit to the bridge, it is packaged using superconducting packaging, vacuum chamber, etc. to reduce external interference and further improve the accuracy of the determined structural state of the bridge.

[0063] Since the quantum bit pairs in the embodiment of the present invention are installed at part of the bridge, that is, the location where the quantum bit pairs are installed is monitored to represent the structural status of the entire bridge, the rationality of the selection of the installation location is closely related to the accuracy of the monitoring of the bridge structure status. Therefore, the installation location should be determined according to the design and structural characteristics of the bridge.

[0064] In a specific embodiment of the present invention, the installation location may be a key node, a support, a beam-column connection, etc. of a bridge.

[0065] In some embodiments of the present invention, step S101 is specifically as follows:

[0066] At least two initial quantum bits are obtained, and a quantum gate operation is performed on the at least two initial quantum bits to obtain at least one quantum bit pair in a quantum entangled state.

[0067] It should be noted that in order to improve the reliability of the monitored bridge structure state, the initial quantum bit should be a quantum bit with stable quantum performance. Specifically, the initial quantum bit is any one of a superconducting quantum bit, an ion trap quantum bit, etc.

[0068] In some embodiments of the present invention, the at least two initial qubits include at least one initial qubit pair, the initial qubit pair includes a first initial qubit and a second initial qubit, and the quantum gate operation includes a controlled NOT gate operation and a Hadamard gate operation. As shown in FIG2 , performing a quantum gate operation on the at least two initial qubits to obtain at least one qubit pair in a quantum entangled state includes:

[0069] S201, performing a controlled-not (CNOT) gate operation on the initial qubit pair to obtain an associated qubit pair, where the associated qubit pair includes a first associated qubit and a second associated qubit;

[0070] S202. Perform a Hadamard gate operation on the first associated quantum bit or the second associated quantum bit to obtain at least one quantum bit pair in a quantum entangled state.

[0071] The expression of the controlled NOT gate in step S201 is:

[0072] Where |0> is the first initial quantum bit in the ground state; <0| is the second initial quantum bit in the ground state; is the Kronecker product operator; I is the identity matrix; |1> is the first initial quantum bit in the excited state; <1| is the second initial quantum bit in the excited state; X is the Pauli X matrix, that is, the quantum NOT gate matrix.

[0073] The purpose of the Hadamard gate operation in step S202 is to make the first associated quantum bit or the second associated quantum bit enter the average state from the ground state, so as to make it entangled with the other quantum bit.

[0074] Specifically, taking the average state of the first correlated quantum bit as an example, the expression of the average state |+> is: |+>=(|0>+|1>) / √2

[0075] It should be noted that the method for controlling whether the first initial quantum bit and the second initial quantum bit are in the ground state or the excited state can be: by applying several light pulses to the first initial quantum bit and the second initial quantum bit in the excited state, the first initial quantum bit and the second initial quantum bit are controlled to be placed in the ground state.

[0076] Since the particularity of the quantum entangled state between quantum bit pairs is utilized when monitoring the bridge, that is, the stronger the correlation of the quantum entangled state, the more accurate the monitoring result, therefore, in a specific embodiment of the present invention, the quantum entangled state between the quantum bit pairs is a Bell state.

[0077] To ensure that the quantum entangled state of the obtained quantum bit pair actually exists, and to ensure the feasibility of monitoring the bridge, in some embodiments of the present invention, after step S101, the following is further included:

[0078] The correlation between the first quantum bit and the second quantum bit is measured, and whether the quantum entangled state exists is confirmed based on the correlation. When the quantum entangled state does not exist, the quantum gate operation is re-performed on the quantum bit pair.

[0079] The embodiment of the present invention can ensure the existence of quantum entanglement in the generated quantum bit pairs by confirming whether the quantum entanglement state of the obtained quantum bit pairs exists, thereby ensuring the feasibility and accuracy of monitoring the bridge through the quantum bit pairs.

[0080] Measuring the correlation between the first qubit and the second qubit may specifically include measuring the Bell inequality or the density matrix of the first qubit and the second qubit, thereby obtaining the correlation.

[0081] Due to the influence of quantum noise and installation errors, the coupling relationship between the constructed quantum bit pair state and the physical parameters of the bridge may be inaccurate. To address this technical problem, in some embodiments of the present invention, as shown in FIG3 , the bridge monitoring method further includes:

[0082] S301, obtaining a reference structural state of the bridge, and determining whether the coupling relationship needs to be adjusted based on the reference structural state and the structural state;

[0083] S302. When the coupling relationship needs to be adjusted, adjust the qubit parameters and / or the position parameters of the qubit to obtain optimized parameters, and obtain an optimized coupling relationship based on the optimized parameters.

[0084] The embodiment of the present invention optimizes the coupling relationship according to the reference structural state and the structural state to obtain an optimized coupling relationship, thereby ensuring the accuracy of the coupling relationship, thereby improving the accuracy of the structural state determined by the coupling relationship, that is, improving the accuracy of the bridge monitoring method and achieving high-precision monitoring.

[0085] The reference structural state may be a structural state with reference significance determined through simulation or multiple experiments.

[0086] It should be noted that the qubit parameters include quantum gate operation parameters, initialization parameters, etc. The position parameter of the qubit refers to the position where the qubit is installed on the bridge.

[0087] In some embodiments of the present invention, the qubit pair state includes the quantum state of the first qubit and / or the second qubit and the quantum entangled state of the qubit pair, and the coupling relationship includes a first coupling relationship between the quantum state and a physical parameter of the bridge and a second coupling relationship between the quantum entangled state and the physical parameter of the bridge; then monitoring the qubit pair state of at least one qubit pair in step S103 includes:

[0088] monitoring the quantum state of the first qubit and / or the second qubit, and determining the structural state of the bridge based on the quantum state and the first coupling relationship;

[0089] and / or,

[0090] The quantum entangled state of the quantum bit pair is monitored, and the structural state of the bridge is determined based on the quantum entangled state and the second coupling relationship.

[0091] It should be noted that monitoring the quantum entangled state of the quantum bit pair can specifically be monitoring the quantum state density matrix of the quantum bit pair.

[0092] Embodiments of the present invention propose determining the structural state of a bridge by monitoring the quantum state of qubits and / or the quantum entangled state of qubit pairs, thus achieving a diverse approach to determining the structural state of the bridge. Furthermore, this combination of methods can identify potential structural issues within the bridge, improving the reliability and accuracy of bridge status monitoring. Furthermore, combining the determination of the structural state of the bridge using both quantum states and quantum entangled states enables highly sensitive and high-resolution monitoring of the bridge structure, providing critical information for bridge maintenance and repair, ensuring bridge safety.

[0093] It should be understood that before monitoring begins, a baseline measurement is performed to record the initial state of the qubits. This serves as a reference point for comparing subsequent measurements. Specifically, the qubit states obtained from real-time measurements are compared with the baseline measurement results. By comparing the changes in the qubit states, changes in the bridge structure, such as stress distribution and damage locations, can be analyzed.

[0094] In order to more intuitively see the structural status of the bridge, in some embodiments of the present invention, as shown in FIG4 , the bridge monitoring method further includes:

[0095] S401, obtaining the time characteristics and position characteristics of the structural state;

[0096] S402: Determine a visualization template based on the time feature and the location feature, and visualize the structural state based on the visualization template.

[0097] This embodiment of the present invention determines a visualization template based on the temporal and locational characteristics of the acquired structural state. This improves the compatibility of the visualization template with the structural state data, thereby enhancing the intuitiveness of the visualized structural state display. Furthermore, visualization can transform abstract data into intuitive images, making it easier to identify patterns, trends, and anomalies in the data. Through visualization, we can better understand changes in bridge structures, identify anomalies and trends, and make appropriate decisions to guide maintenance and repair work.

[0098] In a specific embodiment of the present invention, the time sequence of structural state changes can be determined according to time characteristics, and the bridge structure data can be presented in a visual manner based on visualization templates in the form of graphs, line graphs, etc., to help staff observe the trends, periodic changes, etc. of the bridge structure data; when the number and scale of time characteristics and location characteristics are large, the data distribution and changes of the structural state data can be displayed based on visualization templates such as heat maps to discover spatial and temporal changes; a dynamic demonstration visualization template can also be created to show the changes of data over time, which can help observe the evolution process of structural changes and discover instantaneous changes and trends; visualization templates such as scatter plots and scatter matrices can also be used to display the relationships and correlations between multidimensional data to reveal potential structural information; if the bridge involves multiple geographical locations, Geographic Information System (GIS) technology can be used to display the data results on a map to gain spatial insights.

[0099] It should be noted that, for easier viewing, interactive visualization tools can also be created to allow users to freely explore the data, zoom in, zoom out, and select parts of interest.

[0100] To ensure the safety of the bridge, in some embodiments of the present invention, as shown in FIG5 , the bridge monitoring method further includes:

[0101] S501, determining whether an abnormality occurs in the bridge based on the structural state;

[0102] S502. When an abnormality occurs in the bridge, an alarm message is generated; the alarm message includes an alarm signal, the location of the abnormality, and the abnormality level.

[0103] The embodiment of the present invention quickly generates an alarm message when an abnormal situation in the bridge is monitored, and the alarm signal in the alarm message can be used by operators or maintenance personnel to be informed of the bridge abnormality in the first time, ensuring that quick action can be taken to maintain the safety of the bridge when the bridge structure is threatened.

[0104] Furthermore, the occurrence location in the alarm information can enable maintenance personnel to accurately know the location where the abnormality occurred, so that maintenance personnel can quickly reach the location where the abnormality occurred, thereby improving maintenance and repair efficiency.

[0105] Furthermore, the abnormality level in the alarm information can provide guidance for subsequent maintenance and repair of the bridge, thereby improving maintenance and repair efficiency.

[0106] The alarm signal may be an audible or visual alarm signal.

[0107] It should be noted that the abnormality levels include but are not limited to minor abnormality, moderate abnormality and severe abnormality. Minor abnormality may be slight deformation of the bridge structure, moderate abnormality may be a dent in the bridge, and severe abnormality may be misalignment or fracture of the bridge.

[0108] In order to ensure that the normal use of the bridge is not affected after an abnormality occurs, in some embodiments of the present invention, as shown in FIG6 , the bridge monitoring method further includes:

[0109] S601: Generate a bridge maintenance plan based on the alarm information, and maintain the bridge based on the bridge maintenance plan to obtain a maintained bridge;

[0110] S602, determining a maintenance structure status of a bridge based on at least one quantum bit pair;

[0111] S603: Determine the effectiveness of the bridge maintenance plan based on the maintenance structure status.

[0112] The embodiment of the present invention generates a bridge maintenance plan based on the alarm information, eliminating the need for maintenance personnel to manually formulate a maintenance plan, thereby improving maintenance efficiency. After the maintenance is completed, the status of the quantum bits will be monitored again. By comparing the monitoring results before and after maintenance, it can be confirmed whether the structure has returned to normal and the effectiveness of the maintenance measures.

[0113] It should be noted that the bridge maintenance plan may involve temporary reinforcement, repair or other maintenance methods depending on the level of abnormality.

[0114] High-quality data is the foundation of data processing and analysis. Any data distortion or loss may affect the final monitoring results. By ensuring the accuracy, real-time, and security of the state data of the quantum bit pair, a reliable data source can be provided for the subsequent determination of the bridge structure status, thereby achieving a deeper understanding and analysis of bridge structural changes.

[0115] Therefore, in some embodiments of the present invention, after monitoring the qubit pair state of the at least one qubit pair in step S104, the method further includes:

[0116] The state data of the quantum bit pair state are sequentially subjected to denoising, interpolation and normalization.

[0117] The embodiments of the present invention can remove noise and outliers by sequentially denoising, interpolating, and normalizing the state data of the quantum bit pair state, making the data more analytical. Missing values ​​in the state data can be filled by interpolation to maintain the continuity and consistency of the data. Normalization can make different feature data comparable, ensuring the accuracy and effectiveness of subsequent analysis.

[0118] Among them, the denoising method can be to perform denoising through a filtering algorithm or a smoothing algorithm, or to determine and eliminate outliers in the state data based on a statistical analysis algorithm or a machine learning algorithm.

[0119] It should be noted that feature extraction can also be performed on the state data of the quantum bit pair state to extract meaningful features and eliminate redundant or irrelevant features, thereby improving monitoring efficiency and accuracy.

[0120] The specific process of feature extraction involves selecting appropriate features based on the physical parameters of the bridge. These features can be numerical, spectral, or time-domain, depending on the nature of the data and the analysis objective. The values ​​of the selected features are then calculated based on the raw data. This process may involve statistical calculations, signal processing techniques, and mathematical modeling.

[0121] Through feature extraction, we can transform data into a more compact and understandable form, extracting information relevant to the analysis goal. This not only improves the efficiency of data processing and analysis, but also makes the analysis results more intuitive and meaningful.

[0122] Furthermore, for high-dimensional data, dimensionality reduction may be necessary to reduce the number of features and improve data processing efficiency and analysis speed. Extracted features should be standardized to ensure comparability between different features. This helps improve the accuracy of analysis results. For excessive features, feature selection may be necessary to select features that are more relevant to the analysis objective to reduce redundant information. Based on the actual problem, feature engineering can be performed to design new features or combine features to better reflect the essence of the data.

[0123] In summary, a bridge detection and monitoring method proposed in an embodiment of the present invention utilizes the entanglement relationship of quantum bits to achieve high-sensitivity and high-resolution monitoring of the structural state of the bridge. By preparing the entangled state of quantum bits and deploying them at key locations on the bridge, it is possible to capture tiny structural change signals in real time, thereby promptly discovering and identifying potential abnormalities. By monitoring the changes in the quantum bit state in real time, combined with data processing and analysis algorithms, detailed information on bridge structural changes can be obtained and converted into practical and useful monitoring data. These data can be used to predict structural health, identify abnormalities, and guide maintenance and repair decisions. This method has significant advantages in monitoring subtle changes and remote locations that traditional monitoring methods cannot cover.

[0124] Furthermore, this invention provides an innovative and forward-looking solution for bridge structural health monitoring, which is not only theoretically significant but also holds broad promise for practical application. This method will play a significant role in promoting the safety and sustainability of urban infrastructure, providing strong support for the construction and development of modern cities.
