Description

Technical Field

[0001] This invention relates to the field of design optimization technology, and specifically to an intelligent auxiliary design method, device and system for component assembly. Background Technology

[0002] In prefabricated building construction, precast wall panels and other components are typically fixed to the main concrete structure using post-anchoring connectors. The effective load-bearing capacity of the anchoring points directly determines the safety and durability of the connection joint. Current design methods are based on Building Information Modeling (BIM), which relies on a priori, idealized micromechanical assumption: the concrete substrate in the local area where the anchoring point is located is homogeneous and continuous. However, in actual engineering, concrete exhibits significant spatial heterogeneity in its internal mechanical properties due to material segregation, inadequate compaction, or the development of microcracks. Therefore, the dynamic mechanical interaction between the drill bit and the substrate during drilling is essentially a direct reflection of the energy transfer and dissipation process in a heterogeneous medium. The true load-bearing capacity of the anchoring point substrate is highly dependent on the integrity and stability of this energy transfer path. However, this energy transfer path and its obstructed state are hidden within the concrete and cannot be directly and quantitatively assessed through conventional construction monitoring or post-construction testing methods.

[0003] Existing methods for judging the quality of the foundation based on a single statistical quantity such as average torque or peak torque during the drilling process cannot decouple and quantify the diverse energy transfer obstruction characteristics caused by different microscopic defect mechanisms, such as encountering isolated hard points, entering cavitary and loose areas, or dense microcrack areas. This leads to a serious disconnect between construction judgment and the physical reality of the foundation, which may result in the misjudgment of anchorage points located in high-risk defect areas as qualified, or unnecessary alarms for high-strength uniform foundations. For example, a high torque reading may originate from an ideal concrete foundation or from unfavorable conditions such as the drill bit getting stuck in microcracks. In other words, the accuracy and reliability of existing technologies for auxiliary design of component anchorage points based on a single torque statistic are low. Summary of the Invention

[0004] To address the low accuracy of existing technologies that rely on a single torque statistic for auxiliary design of anchorage points in structural components, this application aims to provide an intelligent auxiliary design method, device, and system for structural components. The specific technical solution adopted is as follows:

[0005] The first aspect of this application provides an intelligent auxiliary design method for component assembly, including:

[0006] The process data of drilling at each anchorage point of a concrete component at a prefabricated building construction site is obtained. The process data includes the instantaneous drilling torque and spindle angular velocity of the electric drill at each sampling moment. Based on the temporal relative changes of the instantaneous drilling torque and spindle angular velocity, the system response stiffness at each sampling moment is determined.

[0007] The moments when the drill bit is obstructed and the moments when the motor increases torque are selected based on the temporal variation of the instantaneous drilling torque; the corresponding degree of energy transfer obstruction is determined based on the temporal difference between each moment when the drill bit is obstructed and each moment when the motor increases torque, the system response stiffness fluctuation deviation, and the neighborhood variation deviation of the instantaneous drilling torque.

[0008] Based on the distribution of energy transfer resistance between the times when each drill bit is obstructed and the times when each motor increases torque, a pair of obstructed torque-increasing times is determined; each pair of obstructed torque-increasing times includes one drill bit obstruction time and one motor torque-increasing time; based on the overall magnitude of the energy transfer resistance of each pair of obstructed torque-increasing times, the overall transmission resistance is determined; based on the consistency of the time interval between each drill bit obstruction time and the corresponding matched torque-increasing time, the response delay consistency is determined.

[0009] The component auxiliary design is carried out based on the consistency between the overall transmission resistance and the response delay.

[0010] Furthermore, the process of obtaining the system response stiffness includes:

[0011] The change in drilling torque at each sampling moment is determined based on the difference between the instantaneous drilling torque at each sampling moment and the instantaneous drilling torque at the previous sampling moment.

[0012] The change in angular velocity at each sampling moment is determined based on the difference between the principal axis angular velocity at each sampling moment and the principal axis angular velocity at the previous sampling moment;

[0013] The system response stiffness at each sampling moment is determined based on the changes in drilling torque and angular velocity.

[0014] Furthermore, the process of selecting the moment when the drill bit is obstructed and the moment when the motor increases torque based on the temporal variation of the instantaneous drilling torque includes:

[0015] Arrange the instantaneous drilling torque at all sampling times in chronological order to determine the instantaneous drilling torque sequence;

[0016] Using the instantaneous drilling torque sequence as input to the peak detection algorithm, the time corresponding to each output peak is taken as the time when the drill bit is obstructed;

[0017] The difference between the instantaneous drilling torque at each sampling moment and the instantaneous drilling torque at the previous sampling moment is taken as the torque difference value at each sampling moment; the torque difference values ​​at all sampling moments are arranged in chronological order to determine the drilling torque difference sequence; the drilling torque difference sequence is used as the input of the peak detection algorithm, and the moment corresponding to each peak value is taken as the moment of motor torque increase.

[0018] Furthermore, the process of obtaining the energy transfer resistance includes:

[0019] Each moment when the drill bit is obstructed is taken as the target obstruction moment, and each moment when the motor increases torque is taken as the target torque increase moment.

[0020] When the moment when the target is blocked occurs after the moment when the target increases torque:

[0021] The time interval between the moment when the target is blocked and the moment when the target increases torque is normalized and used as the torque increase and blockage time delay parameter; the variance of the system response stiffness at all sampling moments between the moment when the target is blocked and the moment when the target increases torque is normalized to determine the ripple of the transmission interval.

[0022] Arrange the instantaneous drilling torque of all sampling moments within the time window of the target obstruction moment in chronological order to determine the target obstruction local sequence; arrange the instantaneous drilling torque of all sampling moments within the time window of the target torque increase moment in chronological order to determine the target torque increase local sequence; and determine the corresponding waveform distortion weight by performing a positive correlation mapping value on the DTW distance between the target obstruction local sequence and the target torque increase local sequence.

[0023] The corresponding reference transmission resistance is determined based on the sum of the torque increase resistance delay parameter and the transmission interval fluctuation; the energy transmission resistance between the target resistance time and the target torque increase time is determined based on the product of the reference transmission resistance and the waveform distortion weight.

[0024] When the moment when the target is blocked is before the moment when the target increases torque or belongs to the same sampling moment, the degree of energy transfer obstruction between the moment when the target is blocked and the moment when the target increases torque is set to the preset obstruction coefficient.

[0025] Furthermore, the process of obtaining the matched pair at the moment of resisted torque increase includes:

[0026] Establish a base transmission resistance matrix; wherein, the rows of the base transmission resistance matrix represent the torque increase times of each motor, the columns of the base transmission resistance matrix represent the resistance times of each drill bit, and each element of the base transmission resistance matrix is ​​the degree of energy transmission resistance between the torque increase time of the motor in the corresponding row and the resistance time of the drill bit in the corresponding column.

[0027] The basis transmission obstruction matrix is ​​input into the Hungarian algorithm, which outputs all obstructed torque-increasing time matching pairs corresponding to the minimum cost.

[0028] Furthermore, the process of obtaining the overall transmission resistance includes:

[0029] The overall transmission resistance is determined by the average of the energy transfer resistance of the matched pair at all times of torque increase under resistance.

[0030] Furthermore, the process of obtaining the response latency consistency includes:

[0031] By negatively correlating the variance of the energy transfer resistance of all time-matched pairs under the obstructed torque increase, the consistency of response delay is determined.

[0032] Furthermore, the process of assisting in component design based on the consistency between the overall transmission resistance and the response delay includes:

[0033] When the overall transmission resistance and the response delay consistency meet the qualification conditions, the anchorage point corresponding to the concrete component is used as a qualified anchorage point for auxiliary design; wherein, the qualification conditions include: the overall transmission resistance is less than or equal to the preset standard resistance threshold, and the corresponding response delay consistency is greater than the preset consistency threshold.

[0034] When the overall transmission resistance and the response delay consistency do not meet the qualification conditions, the corresponding qualified anchor points are marked as unqualified anchor points, and anchor points that meet the qualification conditions are determined in the neighborhood of the unqualified anchor points as qualified anchor points for auxiliary design.

[0035] Secondly, this application provides an intelligent auxiliary design system for component assembly, the system comprising:

[0036] The data acquisition and preprocessing module is used to acquire process data during drilling operations at each anchoring point of a concrete component at a prefabricated building construction site. The process data includes the instantaneous drilling torque and spindle angular velocity of the electric drill at each sampling moment. Based on the temporal relative changes of the instantaneous drilling torque and spindle angular velocity, the system response stiffness at each sampling moment is determined.

[0037] The first determining module is used to filter out the time when the drill bit is obstructed and the time when the motor increases torque based on the temporal variation of the instantaneous drilling torque; and to determine the corresponding degree of energy transfer obstruction based on the temporal difference between each time when the drill bit is obstructed and each time when the motor increases torque, the system response stiffness fluctuation deviation, and the neighborhood variation deviation of the instantaneous drilling torque.

[0038] The second determining module is used to determine the resistance-increasing torque timing matching pair based on the distribution of energy transfer resistance between each drill bit resistance moment and each motor torque increasing moment; the resistance-increasing torque timing matching pair includes one drill bit resistance moment and one motor torque increasing moment; the overall transmission resistance is determined based on the overall magnitude of the energy transfer resistance of each resistance-increasing torque timing matching pair; and the response delay consistency is determined based on the consistency of the time interval between each drill bit resistance moment and the corresponding matching torque increasing moment.

[0039] The auxiliary design module is used to perform auxiliary design of components based on the consistency between the overall transmission resistance and the response delay.

[0040] Thirdly, this application provides an intelligent auxiliary design device for component assembly, including a memory and a processor. The memory is used to store computer program code, and the processor is used to call and run the computer program code from the memory to perform the method as described in the first aspect of this application or any embodiment of the first aspect.

[0041] Fourthly, this application provides a computer program product comprising computer program code, which, when executed, performs the method as described in the first aspect of this application or any embodiment thereof.

[0042] Fifthly, this application provides a computer-readable storage medium that stores computer program code, which, when executed, performs the method as described in the first aspect of this application or any embodiment thereof.

[0043] This application has the following beneficial effects:

[0044] This application first obtains the instantaneous drilling torque and spindle angular velocity during drilling operations at each anchorage point of a concrete component at a prefabricated building construction site. Based on the temporal relative changes in the instantaneous drilling torque and spindle angular velocity, the system response stiffness at each sampling moment is determined. Then, based on the temporal changes in the instantaneous drilling torque, the drilling bit obstruction moment (characterized by significant resistance encountered by the drill bit) and the motor torque increase moment (characterized by a rapid increase in the motor's active output torque) are determined. Furthermore, considering the complex potential causal relationship between the drilling bit obstruction moment and the motor torque increase event, the energy transfer obstruction degree is determined based on the temporal difference between the two, the system response stiffness fluctuation deviation, and the neighborhood change deviation of the instantaneous drilling torque. Based on the energy transfer obstruction degree distribution among all event pairs, the optimal assignment method is used to determine the matching pairs for obstructed torque increase moments. Finally, the overall energy transfer resistance is determined based on the overall energy transfer resistance of the matching pair set, and the response delay consistency is determined based on the consistency of the time intervals of each matching pair. Thus, the auxiliary design of the matching components is carried out based on the two decoupled dimensions of overall energy transfer resistance and response delay consistency, which makes the auxiliary design of the anchoring points of the matching components more accurate.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0051] The following description, in conjunction with the accompanying drawings, details the specific solutions of the intelligent auxiliary design method, equipment, and system for component assembly provided by the present invention.

[0052] This application provides an intelligent auxiliary design method for component assembly. Please refer to [link to relevant documentation]. Figure 1 The diagram illustrates a flowchart of an intelligent auxiliary design method for component assembly according to an embodiment of the present invention. The method includes:

[0053] Step S101: Obtain process data when drilling at each anchor point of the concrete component at the prefabricated building construction site. The process data includes the instantaneous drilling torque and spindle angular velocity of the electric drill at each sampling moment. Based on the temporal relative changes of the instantaneous drilling torque and spindle angular velocity, determine the system response stiffness at each sampling moment.

[0054] The scenario corresponding to this invention is an auxiliary design method for in-situ evaluation of the foundation condition of anchorage points during component installation drilling. Its core lies in transforming standard anchorage drilling operations into an in-situ, quantitative detection process of the foundation's mechanical properties. To this end, initial data collection is first required.

[0055] At each anchorage point of the concrete components on the prefabricated building construction site, the operator uses a smart electric drill integrated with a Hall effect current sensor and a rotary encoder to perform a complete drilling operation. At each sampling moment during the drilling operation, the instantaneous current of the motor drive winding and the instantaneous angular velocity of the spindle (i.e., the spindle angular velocity) are collected. Then, the motor torque constant and the motor no-load current are obtained. The motor torque constant and the motor no-load current are both pre-calibrated through a one-time standard dynamometer experiment on the electric drill equipment used in this embodiment of the invention. Then, based on the instantaneous current at each sampling moment, combined with the motor torque constant and the motor no-load current, the instantaneous drilling torque is converted. Specifically, the difference between the instantaneous current at each sampling moment and the motor no-load current is used as the drilling current difference; the instantaneous drilling torque at each sampling moment is determined by multiplying the drilling current difference by the motor torque constant. In one specific implementation of this embodiment of the invention, the sampling frequency is set to 100Hz, which can be adjusted according to the specific implementation environment.

[0056] To ensure that the embodiments of the present invention only analyze the effective drilling process, the sampling times where the drilling current difference is less than a preset difference threshold are taken as no-load times. In a specific implementation of the embodiments of the present invention, the process of obtaining the preset difference threshold includes: before the drilling operation begins, collecting no-load current data at 30 sampling times during the no-load state after the electric drill starts; using three times the standard deviation of all no-load current data as a no-load correction parameter; determining the no-load current boundary value based on the sum of the mean of all no-load current data and the no-load correction parameter; and determining the preset difference threshold based on the difference between the no-load current boundary value and the motor no-load current. No-load times correspond to the sampling times when the electric drill is in a no-load state and do not belong to the effective drilling process. Therefore, to improve the accuracy of subsequent analysis, all no-load times in the time sequence are further discarded, and other sampling times are merged. That is, no-load times are not included in all sampling times in the embodiments of the present invention. It should be noted that the mean of all no-load current data can also be used as the motor no-load current for analysis in the embodiments of the present invention, which will not be further elaborated here.

[0057] Since the measured change in instantaneous drilling torque is the result of the combined effect of the base load and the response characteristics of the electric drill drive system itself, in order to accurately distinguish between the two in subsequent analysis, an index that can quantify the drive system's ability to resist load disturbances and maintain stable rotational speed, namely system response stiffness, is further established. Preferably, in some possible implementations of the embodiments of the present invention, the process of obtaining system response stiffness includes:

[0058] The drilling torque change value at each sampling moment is determined based on the difference between the instantaneous drilling torque at each sampling moment and the instantaneous drilling torque at the previous sampling moment; the angular velocity change value at each sampling moment is determined based on the difference between the spindle angular velocity at each sampling moment and the spindle angular velocity at the previous sampling moment; and the system response stiffness at each sampling moment is determined based on the drilling torque change value and the angular velocity change value. It should be noted that, considering that a sampling moment does not have a preceding sampling moment, this embodiment sets the ratio between the drilling torque change value and the angular velocity change value at the first sampling moment as a default constant. This default constant can be obtained by averaging the system response stiffness at all other sampling moments, which will not be elaborated further here. Furthermore, it should be noted that the difference in this embodiment essentially represents the absolute value of the difference, which will not be elaborated further here.

[0059] In one specific implementation of this invention, the ratio between the drilling torque change value and the angular velocity change value is used as the system response stiffness at each sampling moment. When the angular velocity change value at a certain sampling moment is 0, the minimum value of the angular velocity change value at all sampling moments with non-zero angular velocity change value is used to replace the angular velocity change value at the corresponding sampling moment in the calculation, so as to avoid the problem of the denominator being 0. If the angular velocity change value at all sampling moments is 0, then 1 is used as the denominator to avoid the problem of the denominator being 0 in this extreme case. Determining the system response stiffness by using the ratio between the drilling torque change and the angular velocity change allows the system response stiffness to characterize the degree of influence of instantaneous torque change on instantaneous speed change. This system response stiffness characterizes the dynamic stiffness characteristics of the electric drill drive system in maintaining a preset speed under external load disturbances. It is used to decouple and quantify the influence of the system's own dynamics on the torque signal in the time domain. This enables the subsequent identification of events corresponding to increased motor torque and drill bit obstruction, as well as the calculation of energy transfer path characteristics, to be based on a purer base load signal that has been stripped of the inherent response influence of the system. This significantly improves the detection sensitivity and diagnostic accuracy of abnormal torque waveforms caused by defects inside concrete.

[0060] Step S102: Filter out the times when the drill bit is obstructed and the times when the motor increases torque based on the temporal changes of the instantaneous drilling torque; determine the corresponding degree of energy transfer obstruction based on the temporal difference between each time the drill bit is obstructed and each time the motor increases torque, the system response stiffness fluctuation deviation, and the neighborhood change deviation of the instantaneous drilling torque.

[0061] Step S101 determines the time series of instantaneous drilling torque characterizing the macroscopic resistance of the substrate and the time series of system response stiffness used to isolate the dynamic effects of the system. However, the magnitude of the instantaneous drilling torque value still has inherent ambiguity: a high torque value may correspond to an ideal high-strength substrate or a failure condition of being stuck in a microcrack. This indicates that relying solely on a continuous torque sequence after system decoupling is insufficient to fundamentally distinguish the diverse physical processes of energy transfer obstruction triggered by different microscopic defect mechanisms. To decouple and quantify the microscopic dynamic characteristics reflecting different physical mechanisms inherent in the macroscopic torque signal, this embodiment of the invention considers that the morphological changes in the torque sequence are essentially a direct reflection of the degree of obstruction in the energy transfer path. Since a complete energy transfer process necessarily includes two distinct stages—excitation and response—the invention further filters out the drill bit obstruction moment and the motor torque increase moment to deconstruct the continuous torque observation at the physical mechanism level. This allows the motor torque increase moment corresponding to the excitation point representing energy input and the drill bit obstruction moment corresponding to the response point representing abnormal energy dissipation to be separated and identified. This provides a data foundation for subsequent analysis of the time delay, waveform distortion, and other relationships between "torque increase-obstruction" event pairs, i.e., obstruction-torque increase moment matching pairs.

[0062] Preferably, in some possible implementations of the embodiments of the present invention, the process of selecting the moment when the drill bit is obstructed and the moment when the motor increases torque based on the temporal variation of the instantaneous drilling torque includes:

[0063] The instantaneous drilling torque at all sampling moments is arranged in chronological order to determine the instantaneous drilling torque sequence. This sequence is used as input to a peak detection algorithm, and the moment corresponding to each output peak is taken as the moment the drill bit encounters resistance. Since the moment of drill bit resistance typically corresponds to the drill bit encountering significant resistance and the torque instantaneously reaching a local maximum, the moment of drill bit resistance can be determined by detecting the local peaks in the drilling torque sequence. Similarly, the moment of motor torque increase typically corresponds to a rapid increase in torque output. Therefore, the moment of motor torque increase can be determined by the temporal variation of drilling torque. In this embodiment, the difference between the instantaneous drilling torque at each sampling moment and the instantaneous drilling torque at the previous sampling moment is taken as the torque difference value at each sampling moment. All torque difference values ​​at sampling moments are arranged in chronological order to determine the drilling torque difference sequence. This sequence is used as input to a peak detection algorithm, and the moment corresponding to each output peak is taken as the moment the motor increases torque.

[0064] It should be noted that, considering that there is no previous sampling time at the first sampling time, in order not to affect the integrity of the embodiments of the present invention, the torque difference value at the first sampling time is set as the torque difference value at the second sampling time in the embodiments of the present invention, which will not be further elaborated here.

[0065] After determining the motor torque increase moment, which characterizes the energy input excitation point, and the drill bit resistance moment, which characterizes the abnormal energy dissipation response point, it is further necessary to determine the motor torque increase moment and the matched drill bit resistance moment belonging to the same "torque increase-resistance" event. For each "torque increase-resistance" event, it usually corresponds to the characteristics of a complete energy transfer process from the motor to the substrate. This energy transfer process is modulated by the non-homogeneity of the concrete substrate, resulting in no natural, explicit one-to-one correspondence between the observed torque increase event set and the resistance event set. Instead, it constitutes a many-to-many potential correlation network. If the pairings most likely to reflect the true physical causality cannot be selected, accurate quantitative analysis of the energy transfer process is impossible. Therefore, in order to further determine the most important causal relationship, this embodiment of the invention determines the corresponding degree of energy transfer obstruction based on the timing difference between each drill bit obstruction moment and each motor torque increase moment, the system response stiffness fluctuation deviation, and the instantaneous drilling torque neighborhood change deviation. Thus, based on the degree of energy transfer obstruction, the comprehensive degree of obstruction of the energy transfer path between the corresponding drill bit obstruction moment and the motor torque increase moment is quantified, providing a data basis for subsequent selection of obstruction and torque increase moment matching pairs.

[0066] Preferably, in some possible implementations of the embodiments of the present invention, the process of obtaining the energy transfer resistance includes:

[0067] Each moment when the drill bit is obstructed is taken as the target obstruction moment, and each moment when the motor increases torque is taken as the target torque increase moment. Based on causal relationships, in the same "torque increase-obstruction" event, i.e., in subsequent obstruction-torque increase moment matching pairs, the target obstruction moment should be chronologically after the target torque increase moment. Therefore, in this invention, when the target obstruction moment is chronologically before the target torque increase moment or belongs to the same sampling moment, the energy transfer obstruction degree between the target obstruction moment and the target torque increase moment is set to a preset obstruction degree coefficient. In a specific implementation of this invention, the preset obstruction degree coefficient is set to 100, which can be adjusted according to the specific implementation environment, but it needs to be significantly larger than the range of energy transfer obstruction degree corresponding to when the target obstruction moment is chronologically after the target torque increase moment, to avoid affecting the determination process of the obstruction-torque increase moment matching pairs. Further details are omitted here.

[0068] When the moment of target obstruction is after the moment of target torque increase in time: normalize the time interval between the moment of target obstruction and the moment of target torque increase as the torque increase obstruction delay parameter; normalize the variance of the system response stiffness at all sampling moments between the moment of target obstruction and the moment of target torque increase to determine the ripple of the transmission interval.

[0069] A larger torque-increase delay parameter indicates a slower energy transfer process between the target torque-increase moment and the target torque-increase moment. Therefore, based on the principle that energy transfer efficiency decreases and response delays occur when the path is blocked or the medium is inhomogeneous, the degree of energy transfer obstruction between the target torque-increase moment and the target torque-increase moment should also be greater. Conversely, greater volatility within the transfer interval indicates a more unstable system dynamic between the target torque-increase moment and the target torque-increase moment. Since stable system dynamics are a prerequisite for efficient and predictable energy transfer, and high volatility indicates random disturbances or unstable path characteristics, the degree of energy transfer obstruction between the target torque-increase moment and the target torque-increase moment should also be greater.

[0070] The instantaneous drilling torque at all sampling moments within the neighborhood time window of the target obstruction moment is arranged in chronological order to determine the target obstruction local sequence; the instantaneous drilling torque at all sampling moments within the neighborhood time window of the target torque increase moment is arranged in chronological order to determine the target torque increase local sequence; the DTW distance between the target obstruction local sequence and the target torque increase local sequence is positively correlated and mapped to determine the corresponding waveform distortion weight. In a specific implementation of this invention, the process of obtaining the neighborhood time window includes: taking the average value of the spindle angular velocity at all sampling moments as the average angular velocity; taking the ratio between twice pi and the average angular velocity as the average time period according to the period calculation principle; and taking the product of the average time period and a preset period multiple as the width of the neighborhood time window; wherein, the preset period multiple is set to 2, which can be adjusted to other positive integers according to the specific implementation environment, so that the width of the neighborhood time window is equal to an integer multiple of the average time period, so that the analysis scale is adapted to the actual rotation process of the borehole, and the size of the neighborhood time window can also be adjusted according to the specific implementation environment, which will not be further elaborated here.

[0071] According to the principle of dynamic time warping algorithm, the smaller the DTW distance between the target obstructed local sequence and the target torque-increasing local sequence, the more similar the shapes of the two torque waveform segments are, and the lower the degree of shape distortion of the corresponding energy waveform after propagation through the concrete medium. Based on the principle that the waveform characteristics are well preserved when energy is transmitted in a homogeneous and continuous medium, but significant distortion occurs when transmitted in a medium with defects or inhomogeneity, the degree of energy transmission obstruction at the time of target obstruction and the time of target torque increase should also be smaller.

[0072] Finally, based on the correlation between the torque-increase delay parameter and the sum of the transmission interval fluctuations, the corresponding reference transmission resistance is determined; based on the product of the reference transmission resistance and the waveform distortion weight, the energy transfer resistance between the target resistance moment and the target torque-increase moment is determined. In a specific implementation of this invention, when the target resistance moment is after the target torque-increase moment in time sequence, the process of obtaining the energy transfer resistance is expressed by the formula: ;in, When the target is blocked Increase torque with target The degree of obstruction to energy transfer between them; When the target is blocked Increase torque with target The time interval between; When the target is blocked Increase torque with target The variance of the system response stiffness at all sampling times between; It is a minimum-maximum normalization function; When the target is blocked Increase torque with target The time delay parameter between the torque-increasing resistance parameters; When the target is blocked Increase torque with target The volatility of the transmission range between them; When the target is blocked The corresponding target obstruction local sequence and target torque increase time The corresponding DTW distance between the target torque-increasing local sequences; When the target is blocked Increase torque with target The waveform distortion weights are mapped positively to ensure that waveform distortion always acts as a penalty on the reference transmission obstruction degree, amplifying its impact. Finally, based on the target obstruction time... Increase torque with target The energy transfer resistance between the two points is calculated by taking the target resistance time after the target torque increase time in time.

[0073] Step S103: Determine the matching pairs of obstructed torque increase times based on the distribution of energy transfer resistance between the obstruction time of each drill bit and the torque increase time of each motor; each obstructed torque increase time matching pair includes one drill bit obstruction time and one motor torque increase time; determine the overall transmission resistance based on the overall magnitude of the energy transfer resistance of each obstructed torque increase time matching pair; determine the response delay consistency based on the consistency of the time interval between each drill bit obstruction time and the corresponding matching torque increase time.

[0074] To accurately quantify the energy transfer process, it is necessary to further screen out the pairs that are most likely to reflect the true physical causality. In step S102, the energy transfer obstruction degree, which characterizes the severity of the obstruction of the potential path, has been determined between the time when the drill bit is obstructed and the time when each motor increases torque. The corresponding energy transfer obstruction degree directly quantifies the "cost" of interpreting the specific "torque increase-obstruction" event pair as a real and effective energy transfer path. The smaller the value, the higher the probability that the pair is a real causal relationship. Therefore, in this embodiment of the invention, the obstructed torque increase time matching pair is determined according to the distribution of the energy transfer obstruction degree between each time the drill bit is obstructed and each time the motor increases torque.

[0075] Preferably, in some possible implementations of the embodiments of the present invention, the process of obtaining the matching pairs of hindered torque increase times includes: establishing a base transmission hindering matrix; wherein, the rows of the base transmission hindering matrix represent the torque increase times of each motor, the columns of the base transmission hindering matrix represent the hindered times of each drill bit, and each element of the base transmission hindering matrix is ​​the degree of energy transmission hindering between the motor torque increase time in the corresponding row and the drill bit hindered time in the corresponding column; inputting the base transmission hindering matrix into the Hungarian algorithm, and outputting all the matching pairs of hindered torque increase times corresponding to the minimum cost.

[0076] The Hungarian algorithm is a classic combinatorial optimization algorithm for solving the assignment problem. Therefore, the minimum cost output represents the total "hindrance cost" of the pair that minimizes the overall energy transfer obstruction among all possible matching schemes. In other words, the matching pairs with obstructed torque-increasing moments corresponding to the matching results obtained based on the minimum cost essentially constitute the "torque-increasing obstruction" event sequence that is most likely to reflect the real physical causal relationship in a mathematically optimal sense. It should be noted that, considering the Hungarian algorithm requires the input to be a square matrix, and the possibility that the number of drill bit obstruction moments and motor torque-increasing moments may differ (e.g., the number of drill bit obstruction moments is less than or greater than the number of motor torque-increasing moments), the base transfer obstruction matrix needs to be expanded to make the number of columns equal to the number of rows, and all the supplemented elements are set to 100 to avoid the influence of the supplemented elements on the optimal matching result.

[0077] After identifying the matching pairs of hindered torque-increasing moments that represent the most significant causal relationship, this invention extracts features from the set of such matching pairs to further refine macroscopic indicators that can comprehensively and quantitatively assess the base risk level of the entire drilling process. Specifically, although each matching pair contains hindered information for a specific path, a single pair cannot reflect the overall base condition, and the differences between pairs contain important stability information. Therefore, it is necessary to perform macroscopic statistics on the energy transfer hindered degree corresponding to all matching pairs to determine the overall energy transfer hindered degree that comprehensively reflects the base's overall obstruction to energy transfer; simultaneously, the consistency of the time intervals corresponding to all matching pairs is analyzed to determine the response delay consistency that reflects the temporal reliability of the energy transfer process. Thus, a quantifiable and comparable comprehensive assessment basis for the base condition is provided in terms of both the overall hindered severity and the delay fluctuation.

[0078] Therefore, in this embodiment of the invention, the overall transmission resistance is first determined based on the overall magnitude of the energy transmission resistance of the matching pair at each time of resistance and torque increase; then, the response delay consistency is determined based on the consistency of the time interval between each drill bit resistance time and the corresponding matching torque increase time.

[0079] Preferably, in some possible implementations of the embodiments of the present invention, the process of obtaining the overall transmission resistance includes: determining the overall transmission resistance based on the average energy transmission resistance of all matched pairs at the time of torque increase during the entire drilling process. For all matched pairs at the time of torque increase during the entire drilling process, the greater the corresponding overall transmission resistance, the stronger the average comprehensive resistance experienced by the motor output energy when it reaches the base and causes a response.

[0080] Preferably, in some possible implementations of the embodiments of the present invention, the process of obtaining response latency consistency includes:

[0081] By negatively correlating the variances of the energy transfer resistance degrees of all matched pairs of time-limited torque-increasing events, the consistency of response delays is determined. For all matched pairs of time-limited torque-increasing events, the greater the consistency of their corresponding response delays, the smaller and more stable the time interval fluctuations between "torsion increase" and "resistance" in each energy transfer event, reflecting a highly predictable temporal pattern in the energy transfer process in the substrate.

[0082] In one specific implementation of this invention, the process of obtaining response latency consistency includes: ;in, For anchoring points Consistency of response delay during drilling operations. For anchoring points The variance of the energy transfer resistance of the matching pair at all moments of torque increase during drilling operations.

[0083] Step S104: Perform component auxiliary design based on the overall transmission resistance and response delay consistency.

[0084] When a drill bit drills into a uniform and dense concrete matrix, it typically exhibits a clear energy transfer path and stable and predictable resistance. Therefore, the smaller the overall energy transfer resistance and the greater the consistency of response delay, the more the corresponding anchor point conforms to the homogeneous and continuous base conditions assumed in the ideal design. Consequently, the actual load-bearing capacity and reliability of the anchor point better meet the original structural safety design requirements. Therefore, the auxiliary design of the components is finally carried out based on the overall energy transfer resistance and the consistency of response delay.

[0085] Preferably, in some possible implementations of the embodiments of the present invention, the process of auxiliary design of components based on the consistency of overall transmission resistance and response delay includes:

[0086] When the overall transmission resistance and response delay consistency meet the qualification criteria, the anchor points corresponding to the concrete components are used as qualified anchor points for auxiliary design. The qualification criteria include: the overall transmission resistance is less than or equal to a preset standard resistance threshold, and the corresponding response delay consistency is greater than a preset consistency threshold. Since drilling in a uniform, dense concrete matrix typically corresponds to a smaller overall transmission resistance and a larger time delay consistency, using an overall transmission resistance less than or equal to the preset standard resistance threshold and a response delay consistency greater than the preset consistency threshold as qualification screening conditions ensures that qualified anchor points correspond to a uniform, dense concrete matrix, improving the accuracy and reliability of the auxiliary design of component anchor points.

[0087] In one specific implementation of this invention, the process of obtaining the preset standard resistance threshold includes: conducting multiple drilling experiments on a batch of healthy, homogeneous concrete standard test blocks in a laboratory environment; calculating the average value of the overall transmission resistance when drilling all anchor points of all concrete standard test blocks, as the first reference average value; taking three times the standard deviation of the overall transmission resistance when drilling all anchor points of all concrete standard test blocks, as the first reference standard deviation; and taking the sum of the first reference standard deviation and the first reference average value as the preset standard resistance threshold.

[0088] In one specific implementation of this invention, the process of obtaining the preset consistency threshold includes: calculating the mean of the response delay consistency of all anchor points of all concrete standard test blocks during drilling operations, as a second reference mean; taking three times the standard deviation of the response delay consistency of all anchor points of all concrete standard test blocks during drilling operations, as a second reference standard deviation; and determining the preset consistency threshold based on the difference between the second reference mean and the second reference standard deviation. The threshold selected by this method conforms to the quality control principle of establishing statistical control limits based on known good samples, and will not be further elaborated here.

[0089] Among all anchor points that do not meet the qualification conditions: For anchor points where the response delay consistency is greater than the preset consistency threshold but the overall transmission resistance is greater than the preset standard resistance threshold, the corresponding energy transmission resistance is high, but the response delay remains consistent. This corresponds to the drill bit encountering one or a few large, high-strength aggregates, causing a sudden surge in torque, but the overall material of the base remains relatively uniform, i.e., the drill bit encountering isolated hard points. For anchor points where the overall transmission resistance is less than or equal to the preset standard resistance threshold but the response delay consistency is less than or equal to the preset consistency threshold, the corresponding energy transmission resistance is low, but the response delay is extremely unstable. This corresponds to the drill bit entering an unconstrained cavity or an extremely loose area, causing the load torque to be intermittent, and the causal relationship between the motor torque increase and the drill bit resistance becomes chaotic and inconsistent, i.e., the drill bit entering a cavity or an uncompacted area. For anchor points where the overall transmission resistance is greater than the preset standard resistance threshold and the response delay consistency is less than or equal to the preset consistency threshold, the energy transmission resistance is high and the response delay is unstable. This corresponds to the drill bit drilling in an extremely uneven region composed of hard aggregate and soft mortar or microcracks, resulting in a drilling process that is both laborious and unstable.

[0090] When the overall transmission obstruction and response delay consistency do not meet the qualification conditions, the corresponding qualified anchor points are marked as unqualified anchor points. Within the neighborhood of the unqualified anchor points, anchor points that meet the qualification conditions are identified as qualified anchor points for auxiliary design. Specifically: when the current anchor point is an unqualified anchor point, a geometric constraint search is performed within a preset search radius centered on the current anchor point, generating a candidate point grid within the corresponding circular search area, for example, with a grid spacing of 10 mm. For each candidate point on the grid, the system performs a safety check. A location is considered safe only if it simultaneously meets the following two conditions: First, the minimum distance between its drilling path and the centerline of all designed reinforcing bars is greater than a safety gap, which is equal to the reinforcing bar radius plus the concrete cover thickness required by the specification; Second, the center distance between its location and the currently known unqualified anchor points and other adjacent anchor points meets the minimum spacing required by the specification. In this embodiment, the preset search radius is set to 150 mm, and the minimum spacing required by the specification is set to 60 mm, which can be adjusted according to the specific implementation environment. Candidate points that meet the safety verification criteria are used as candidate anchor points for iterative calculation of overall transmission resistance and response delay consistency. If multiple candidate anchor points meet the qualification criteria, the candidate anchor point closest to the current anchor point is selected as the qualified anchor point for auxiliary design. If no qualified anchor point is found within the preset search radius, the search radius is expanded in 10mm increments until a qualified anchor point is obtained.

[0091] In summary, an intelligent auxiliary design method for prefabricated building components first acquires process data during drilling operations at each anchorage point of the concrete component at the prefabricated building construction site. Based on the temporal relative changes in instantaneous drilling torque and spindle angular velocity, the system response stiffness at each sampling moment is determined. Then, based on the temporal changes in instantaneous drilling torque, the drill bit obstruction moment (characterized by significant resistance encountered by the drill bit) and the motor torque increase moment (characterized by a rapid increase in the motor's active output torque) are determined. Furthermore, considering the complex potential causal relationship between the drill bit obstruction moment and the motor torque increase event, the energy transfer obstruction degree is determined based on the temporal difference between the two, the system response stiffness fluctuation deviation, and the neighborhood change deviation of the instantaneous drilling torque. Finally, based on the distribution of energy transfer obstruction degree among all event pairs, the optimal assignment method is used to determine the matching pairs for obstructed torque increase moments. Finally, the overall energy transfer resistance is determined based on the overall energy transfer resistance of the matching pair set, and the response delay consistency is determined based on the consistency of the time intervals of each matching pair. Thus, the auxiliary design of the matching components is carried out based on the two decoupled dimensions of overall energy transfer resistance and response delay consistency, which makes the auxiliary design of the anchoring points of the matching components more accurate.
