[0002] Object deformation is a common phenomenon in everyday life, such as the tilt of buildings, the deformation of bridges, and the movement of mine slopes. Typically, object deformation does not occur suddenly, but rather accumulates from small amounts of deformation, resulting in a noticeable change at a certain moment. With the development of mobile communication systems such as Beyond 5th Generation (B5G) and Sixth Generation (6G), integrated communication and perception base stations will be widely deployed, capable of providing 24 / 7 communication services and ubiquitous perception services, providing convenient and efficient services for human life.

[0003] Utilizing the perception capabilities of mobile communication systems to continuously observe the deformation of objects in the environment during their deformation is crucial for analyzing their deformation state and guiding operations such as maintenance, management, and safe production. Currently, during this continuous observation process, sensing nodes must report all perceived data to the sensing network element, resulting in excessive system overhead and low observation efficiency.

[0028] The present application is described below in conjunction with the accompanying drawings and embodiments. It will be understood that the specific embodiments described herein are merely intended to explain the present application and are not intended to limit the present application. It should be noted that, unless there is a conflict, the embodiments and features within the embodiments of the present application may be combined with each other in any manner. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present application, not all structures.

[0029] FIG1 is a flow chart of a deformation sensing method provided by an embodiment, which can be applied to a first node. As shown in FIG1 , the method provided by this embodiment includes the following steps:

[0030] In step 110, a sensing instruction from the second node is received, where the sensing instruction includes information of the target to be detected.

[0031] In step 120, according to the sensing instruction, measurement data of the target to be measured is acquired by sending an integrated waveform to the target to be measured.

[0032] In step 130, the perception information of the target to be measured is reported to the second node.

[0033] When the first condition is met, the perception information includes the measurement data; when the second condition is met, the perception information includes deformation information determined based on the measurement data.

[0034] In this embodiment, both the first node and the second node have sensing capabilities. The first node can be used to obtain measurement data of the target and report the measurement data to the second node. The second node then processes the measurement data to analyze the deformation of the target. The first node can also be referred to as a sensing node, and the second node can also be referred to as a sensing network element.

[0035] The second node can send a perception instruction to the first node based on application requirements. The perception instruction can also be understood as a perception request, which is used to instruct or request the first node to measure and perceive the target to be measured. The target to be measured can refer to an object or area of ​​interest, that is, an object or area that needs to be measured. After receiving the perception instruction and completing the perception configuration, the first node can send an integrated waveform to the target to be measured to obtain the measurement data of the target to be measured. The integrated waveform can simultaneously meet the waveform requirements of communication and radar signals, completely or highly integrating communication and perception, and realizing information transmission and physical parameter measurement.

[0036] The first condition may mean that the first node is unsuitable for analyzing and calculating the measurement data, such as when the first node lacks or has poor computing power, when the first node has insufficient battery life, when the first node has insufficient memory, or when the second node has sufficient computing resources. If the first condition is met, the first node can report the measurement data to the second node, which then analyzes the deformation of the measured object based on the measurement data. In this case, deformation measurement and perception are primarily performed by the first node, while deformation calculation and analysis are primarily performed by the second node.

[0037] The second condition may refer to the first node supporting the analysis and calculation of the measurement data, such as the first node having computing power or strong computing power, the first node having sufficient remaining power, or the first node having sufficient remaining memory. When the second condition is met, the first node can determine the deformation information of the target to be measured based on the measurement data, and report the deformation information to the second node. In this case, the calculation and analysis of the deformation can also be completed or shared by the first node, which can reduce the processing pressure of the second node. For example, for scenarios where there are a large number of first nodes, a large number of targets to be measured, insufficient computing resources of the second node, or an overload on the second node, the first node can report the deformation information of the target to be measured.

[0038] In the deformation perception method of the embodiment of the present application, during the continuous observation of the target to be measured, the first node can flexibly report the perceived data to the second node. It can directly report the measurement data or report the deformation information obtained by calculating the measurement data. The first node and the second node cooperate to complete the measurement perception, which can meet the system overhead requirements and improve efficiency.

[0039] In addition, the second node can be configured with a preset deformation threshold. If the deformation information of the target to be measured exceeds the preset deformation threshold, the first node or the second node can send an early warning message to the application end (such as a user terminal such as a computer or mobile phone).

[0040] In addition, the first node or the second node can also predict the deformation trend of the target to be measured in the future based on the deformation information, and provide guidance for subsequent monitoring and maintenance work.

[0041] In one embodiment, the method further comprises:

[0042] S122: Calculate deformation information of the target to be measured based on the measurement data.

[0043] In this embodiment, the first node can determine the deformation information of the target to be measured based on the measurement data and report the deformation information to the second node. In one embodiment, the method further includes:

[0044] S140: Predicting a deformation trend of the target to be measured based on the deformation information.

[0045] In this embodiment, the first node can also predict the deformation trend of the target over a period of time based on the deformation information, thereby providing early warning of significant deformation that may occur in the future. Significant deformation can refer to deformation exceeding a preset deformation threshold or reaching a certain level of deformation that requires maintenance or management measures. In this case, the reported perception data can also include the predicted deformation trend.

[0046] In one embodiment, the deformation information includes at least one of the following:

[0047] Time series information, where each column of the time series information corresponds to the scattering information measured at each distance and each angle at the corresponding moment in the column;

[0048] Interference information, the interference information is obtained by sequentially conjugating the non-reference column with the reference column in the time series information. The reference column is the column corresponding to the reference time, and the non-reference column is the column corresponding to the time other than the reference time;

[0049] Interference phase information, where the interference phase information is determined according to the phase of the interference information;

[0050] Coherence information, the coherence information is determined by modulo the interference information;

[0051] Deformation variable information, the deformation variable information including the deformation variable at each time relative to the reference time except the reference time, the deformation variable information being determined based on the interference information or the interference phase information;

[0052] first deformation curve information, the first deformation curve information being determined according to deformation amount information of the designated target at different times relative to a reference time;

[0053] Second deformation curve information, the second deformation curve information includes deformation amounts of targets at the same angle but different distances at a specified time relative to a reference time;

[0054] Third deformation curve information, the third deformation curve information includes deformation amounts of targets at the same distance but different angles at a specified time relative to a reference time;

[0055] a first deformation trend, the first deformation trend being determined according to a deformation curve of a target distributed along a distance at a specified angle;

[0056] a second deformation trend, the second deformation trend being determined according to a deformation curve of a target distributed along an angle at a specified distance;

[0057] Vibration amplitude, the vibration amplitude is determined according to the deformation information;

[0058] Vibration frequency: The vibration frequency is determined based on the deformation information.

[0059] In this embodiment, the integrated waveform emitted by the first node is reflected by the target to be measured, and the first node receives the reflected echo from the target to be measured. By continuously observing the target to be measured, deformation information of the target to be measured can be obtained. The sensing node that transmits the integrated waveform and receives the reflected echo can be the same or different. The first node or the second node can obtain deformation information by analyzing the measurement data. The deformation information can be one or more of the following:

[0060] 1) Time series information of measurement data: expressed as t1, t2...t N N measurement moments can be represented as a two-dimensional image. Each column in the image contains scattering information at all target distances and angles. This scattering information can be (i.e., discontinuous) scattering information at a specific distance and angle, i.e., scattering information at the target to be measured. Figure 2 is a schematic diagram of time series information provided by one embodiment. Assuming there are M targets of interest, the size of the two-dimensional image is M*N.

[0061] 2) Interference Information: Multiply columns 2 through N of the two-dimensional image conjugately with column 1 to obtain a new two-dimensional image (denoted as I) of size M*(N-1). Note that column 1, corresponding to time t1, is selected here, where t1 is the reference time. The reference time can be the initial time or another time. Multiply each column except the column corresponding to the reference time conjugately with the column corresponding to the reference time to obtain the new two-dimensional image I.

[0062] 3) Interference phase information: The interference phase map can be obtained by taking the phase of the above two-dimensional image I, that is, in, represents an interference phase diagram, and Phase() represents a phase operation. FIG3 is a schematic diagram of an interference phase diagram provided by an embodiment.

[0063] 4) Coherence information: The coherence map can be obtained by taking the modulus of the above two-dimensional image I, that is, in, represents a coherence graph, and abs() represents a modulo operation. This process usually requires normalization according to the coherence calculation formula. FIG4 is a schematic diagram of a coherence graph provided by an embodiment.

[0064] In addition, the above coherence information can be used as a reference for confidence. If the coherence value is large, it means the confidence is high, and if the coherence value is small, it means the confidence is low.

[0065] 5) Deformation information: Using the interference information or the above-mentioned interference phase diagram, the deformation at different times relative to the reference time or the initial time can be calculated according to the deformation inversion formula. The calculation formula is as follows:

[0066] Among them, ΔR represents the size of the deformation, λ represents the wavelength of the synaesthesia integration signal, represents the measured phase difference, f c represents the carrier frequency of the synaesthesia integration signal, and c represents the speed of light.

[0067] 6) First deformation curve information: This is determined based on the deformation information of the specified target at different times relative to a reference time. This information is based on the deformation curves of the M targets obtained through inversion over time. A deformation curve for a specific target can also be drawn as needed. Figure 5 is a schematic diagram of first deformation curve information provided by one embodiment. As shown in Figure 5, the horizontal axis represents different times (Time), in seconds (s), and the vertical axis represents the deformation (Deformation or Displacement) of the specified target at different times relative to a reference time, in millimeters (mm).

[0068] 7) Second deformation curve information: According to the deformation curve of the target distributed along different distances at a certain angle, that is, the deformation of the target at the same angle and different distances at other times relative to the reference time, the deformation trend can be fitted based on this. In addition, the reliability of the target deformation at different distances can be judged in combination with the coherence. If the coherence of a certain distance is low, the deformation information is unreliable and the fitted curve is unreliable. Figure 6 is a schematic diagram of a second deformation curve information provided by an embodiment. As shown in Figure 6, the horizontal axis represents different distances (Range), the unit is meter (m), and the vertical axis represents the deformation (Deformation or Displacement) of the target at different distances relative to the reference time, the unit is millimeter (mm). The deformation in the area with a distance of about 2700 meters, such as the area marked with a circle in the figure, has a low coherence (needs to be judged in combination with the coherence diagram), and the deformation information fitted here is unreliable.

[0069] 8) Third deformation curve information: The deformation curve of the target distributed along different angles at a certain distance, that is, the deformation of the target at the same distance and different angles at other times relative to the reference time, can be used to fit the deformation trend. In addition, the reliability of the target deformation at different angles can be judged in combination with the coherence. If the coherence of a certain angle is low, the deformation information is unreliable, and the fitted curve is unreliable. Figure 7 is a schematic diagram of a third deformation curve information provided by an embodiment. As shown in Figure 7, the horizontal axis represents different angles (Angle), the unit is degree (°), and the vertical axis represents the deformation (Deformation or Displacement) of the target at different angles relative to the reference time, the unit is millimeter (mm).

[0070] 9) Vibration amplitude: The micro-deformation vibration amplitude of the target to be measured can be extracted based on the deformation information of the target.

[0071] 10) Vibration frequency: The micro-deformation vibration frequency of the target to be measured can be extracted based on the deformation information of the target.

[0072] In one embodiment, reporting the perception information of the target to be measured to the second node includes one of the following:

[0073] Periodically reporting the sensing information of the target to be measured to the second node, wherein the period for reporting the sensing information may be configured by the second node or determined by the first node;

[0074] Upon receiving a reporting request from the second node, reporting the perception information of the target to be measured to the second node;

[0075] Report when the deformation information exceeds the preset deformation threshold;

[0076] Report when the deformation trend contains deformation information exceeding the preset deformation threshold;

[0077] The preset deformation threshold is usually configured by the second node, and may also be determined by the first node.

[0081] S160: When the deformation trend includes deformation information exceeding a preset deformation threshold, a second warning message and a confidence level are sent to the application end.

[0082] In this embodiment, the confidence level may be used to indicate the reliability of the predicted deformation trend, or the credibility of the second warning message. It may also be understood as the probability that the deformation trend contains deformation information exceeding a preset deformation threshold.

[0083] In one embodiment, the confidence level is determined based on interference information in the deformation information.

[0084] In this embodiment, the confidence level may be determined based on interference information in the deformation information, for example, based on coherence information.

[0122] In one embodiment, the target to be detected includes a continuously distributed target or area, or a discretely distributed target or area.

[0123] In this embodiment, the target to be measured may be a continuously distributed target or area, or a discretely distributed target or area.

[0124] The deformation sensing method of the present application is exemplified below through some embodiments.

[0125] Example 1

[0126] In this embodiment, the first node is, for example, a sensing node, and the second node is, for example, a sensing network element. The sensing node does not have computing capabilities and may periodically report raw measurement data to the sensing network element. The target to be measured is an area, namely, a target area.

[0127] Based on application requirements, the sensing network element sends sensing instructions (or sensing requests) to the sensing node. After completing the sensing configuration, the sensing node sends an integrated waveform to the target area to obtain measurement data for the target area. To reduce system overhead, the sensing network element can inform the sensing node of the target area of ​​interest. Based on the target area information sent by the sensing network element, the sensing node periodically reports the measurement data of the target area to the sensing network element. The sensing node calculates the deformation information of the target area based on the received measurement data and predicts future deformation trends based on the calculated deformation information.

[0128] In addition, the perception network element can determine whether the current deformation information has exceeded the preset deformation threshold based on the preset deformation threshold. If it exceeds, a short message (i.e., a first warning message) can be sent to the application end for warning. If the predicted deformation trend also exceeds the preset deformation threshold, a short message (i.e., a second warning message) can be sent to the application end for warning. At the same time, the confidence level of the second warning message can also be sent to the application end. The above confidence level indicates the reliability of the predicted future deformation trend. The application end can provide guidance for the next step of work based on the warning message and confidence level issued by the perception network element.

[0129] Example 2

[0130] In this embodiment, the first node is, for example, a sensing node, and the second node is, for example, a sensing network element. The sensing node has computing capabilities and can periodically report raw measurement data to the sensing network element. The target to be measured is an area, namely, a target area.

[0131] Because the sensing node has computing power, it can process the measurement data and obtain deformation information of the target area. This deformation information is the preliminary perception information of the target area. The sensing node periodically reports this deformation information to the sensing network element. The sensing network element analyzes the deformation information and compares it with the preset deformation threshold to determine whether the current deformation information has exceeded the preset deformation threshold. If it exceeds the preset deformation threshold, it can send a short message (i.e., a first warning message) to the application end for warning. In addition, the sensing network element can also predict the deformation trend in the future based on the above deformation information. If the predicted deformation trend also exceeds the preset deformation threshold, it can also send a short message (i.e., a second warning message) to the application end for warning, and can also send a confidence level to the application end. The application end can provide guidance for the next step based on the warning message and confidence level issued by the sensing network element.

[0132] Example 3

[0133] In this embodiment, the first node is, for example, a sensing node, and the second node is, for example, a sensing network element. The sensing node has computing capabilities and reports deformation information to the sensing network element based on a triggering event. The triggering event may be: deformation information exceeding a preset deformation threshold. The target to be measured is an area, namely, a target area.

[0134] Because the sensing nodes possess computing power, they can process the measured data and derive deformation information from it. The sensing network element sends a preset deformation threshold to the sensing node. The sensing node directly analyzes this deformation information and compares it with the preset deformation threshold to determine whether the current deformation information exceeds the preset deformation threshold. If so, the sensing node reports the deformation information to the sensing network element; otherwise, the sensing node does not report the deformation information. If the current deformation information exceeds the preset deformation threshold, the sensing node or sensing network element can send a short message (i.e., a first warning message) to the application end as an early warning.

[0135] Furthermore, if the sensing network element receives deformation information reported by a sensing node, it can also request the application to send a short message (i.e., a second warning message) to issue a warning and also send a confidence level to the application. The application can then provide guidance for the next step based on the warning message and confidence level sent by the sensing network element.

[0136] Example 4

[0137] In this embodiment, the first node is, for example, a sensing node, and the second node is, for example, a sensing network element. The sensing node has computing capabilities and reports deformation information according to a reporting request from the sensing network element. The target to be measured is an area, namely, a target area.

[0138] Because the sensing node has computing capabilities, it can process the measured data and obtain deformation information of the target area. If the sensing node receives a reporting request from the sensing network element, it reports the deformation information to the sensing network element. Otherwise, it may report the deformation information in accordance with the methods described in the second or third embodiments. If the sensing network element receives the sensing information reported by the sensing node as requested, it may analyze the deformation information and compare it with a preset deformation threshold to determine whether the current deformation information exceeds the preset deformation threshold. If so, it may send a short message (i.e., a first warning message) to the application end to issue a warning. In addition, the sensing network element may also predict the deformation trend over a period of time based on the deformation information. If the predicted deformation trend also exceeds the preset deformation threshold, it may also send a short message (i.e., a second warning message) to the application end to issue a warning and may also send a confidence level to the application end. The application end may provide guidance for the next step based on the warning message and confidence level issued by the sensing network element.
