Abstract
Description
Technical Field
[0001] This invention relates to the field of intelligent cable delivery technology, specifically to a high-temperature resistant superconducting cable and its intelligent cable connection delivery equipment. Background Technology
[0002] In the wiring operations of superconducting power systems, high-temperature resistant superconducting cables, due to their special material composition and structural characteristics, place extremely high demands on the conveying accuracy, clamping force control, and environmental adaptability during the wiring process. Traditional cable conveying equipment mostly adopts manual or semi-automatic methods, using upper and lower pressure rollers to clamp and convey the cable. The conveying speed and clamping pressure usually depend on the operator's experience to set, lacking the ability to adaptively adjust to real-time operating conditions such as cable diameter, material hardness, and working temperature.
[0003] In the existing technology, although some conveying equipment is equipped with motor drive and pressure regulation mechanism, its control method is mostly open loop or simple proportional control, which cannot dynamically correct the operating parameters according to the actual stress state of the cable, the conveying displacement error and the changes in ambient temperature. Especially in high temperature environment, the output efficiency of servo motor will decrease and the mechanical structure will have thermal expansion, which will cause the preset conveying parameters to deviate significantly from the actual operating state. This can easily cause fluctuations in cable clamping force, conveying slippage or increased cumulative displacement error, ultimately affecting the positioning accuracy of the connector and even damaging the core structure of the superconducting cable.
[0004] In addition, existing equipment generally lacks the ability to fuse and process multi-source physical quantities in real time. The data collected by different sensors, such as pressure, rotation speed, displacement, and temperature, have different dimensions and are difficult to use directly for unified intelligent decision-making. At the same time, after long-term operation, systematic errors such as mechanical wear and sensor zero-point drift cannot be effectively compensated, resulting in a decrease in the repeatability of the equipment and failing to meet the requirements of high reliability and high consistency for superconducting cable wiring operations.
[0005] Therefore, developing an intelligent superconducting cable connection and transmission device that can sense multi-source operating conditions in real time, intelligently correct transmission parameters, and adapt to high-temperature environments is a technical problem that urgently needs to be solved in this field. Summary of the Invention
[0006] To address the technical problems in the prior art, this application provides a high-temperature resistant superconducting cable and an intelligent cable connection and transmission device thereof.

[0009] Preferably, the multi-source physical quantity real-time acquisition module is used to acquire real-time physical quantities associated with the conveying equipment. The real-time physical quantities include at least the actual clamping pressure of the pressure roller, the real-time speed of the servo motor, the cable conveying displacement, the cable outer diameter, and the working environment temperature.
[0010] Preferably, the data normalization preprocessing module is used to perform minimum-maximum normalization processing on all acquired real-time physical quantities, map the original physical quantities into dimensionless parameters, and output the normalized parameter set to the feature parameter extraction module.

The clamping adaptation coefficient is used to characterize the matching degree between the current clamping pressure and the cable diameter, and the temperature influence coefficient is used to compensate for the influence of high temperature environment on the output efficiency of servo motor components and the thermal expansion of mechanical structure.
[0012] Preferably, the initial conveying parameter generation module generates an initial normalized target speed based on the clamping adaptation coefficient and the temperature influence coefficient, combined with a preset benchmark normalized speed.
[0013] Preferably, the clamping pressure real-time correction module is used to perform a first correction on the initial normalized target rotation speed based on the deviation between the current actual clamping pressure and the target clamping pressure, output the dimensionless target rotation speed after the first correction, and set a first correction threshold for validity determination.
[0014] Preferably, the conveying displacement PID correction module is used to perform a second correction on the dimensionless target speed after the first correction based on the error between the target conveying displacement and the actual conveying displacement using a position-type PID control algorithm, outputs the dimensionless target speed after the second correction, and has a second correction threshold for effectiveness determination.
[0015] Preferably, the preset database Euclidean distance comparison and confirmation module is used to calculate the spatial distance between the real-time running feature vector and the ideal standard vector in the database, and to confirm the final normalized rotational speed based on the comparison result with the database comparison threshold; if the spatial distance is greater than the comparison threshold, a weighted average strategy is used for smoothing correction.
[0016] Preferably, the speed inversion and mechanical execution output module is used to invert the final normalized speed into an actual physical speed command and send it to the driver of the servo motor assembly to drive the servo motor assembly to operate.
[0017] Preferably, the real-time closed-loop feedback module cyclically executes the multi-source physical quantity real-time acquisition module, data normalization preprocessing module, conveying characteristic parameter extraction module, initial conveying parameter generation module, clamping pressure real-time correction module, conveying displacement PID correction module, preset database Euclidean distance comparison and confirmation module, and speed inversion and mechanical execution output module at a fixed cycle, forming a closed-loop control of the cable conveying process.
[0018] In summary, this application includes at least one of the following beneficial technical effects:
[0019] 1. This invention, through the multi-source physical quantity real-time acquisition module and data normalization preprocessing module built into the control unit, can collect multi-dimensional physical quantities such as clamping pressure, motor speed, conveying displacement, cable outer diameter and ambient temperature in real time, and uniformly map them into dimensionless parameters. This eliminates the influence of different physical dimensions on subsequent algorithm fusion calculations, provides a standardized and highly compatible data foundation for intelligent control, and significantly improves the adaptability to different cable specifications and working conditions.
[0020] 2. This invention, through the synergistic effect of the characteristic parameter extraction module, the initial transport parameter generation module, and the clamping pressure real-time correction module, dynamically adjusts the target rotation speed based on the clamping adaptation coefficient and the temperature influence coefficient, and performs the first correction based on the deviation between the actual clamping pressure and the target pressure. This effectively avoids transport slippage caused by insufficient pressure or cable damage caused by excessive pressure, and achieves constant pressure adaptation transport of superconducting cables, ensuring the integrity of the cable and the stability of transport during the wiring process.
[0021] 3. This invention further introduces a conveying displacement PID correction module and a preset database Euclidean distance comparison and confirmation module. It uses a position-based PID control algorithm to correct the conveying displacement error for the second time, and performs a third weighted smoothing correction by comparing the spatial distance with the ideal standard vector in the database. This forms a three-level progressive control logic, which eliminates the cumulative displacement error and the systematic slow-change error generated by long-term operation, ensuring that the wiring terminal can accurately reach the work position, and greatly improving the repeatability and reliability of wiring positioning.
[0022] 4. This invention uses a real-time closed-loop feedback module to cyclically execute each acquisition, correction, and output module at a fixed period, forming a millisecond-level closed-loop control mechanism. This mechanism can automatically compensate for the impact of servo motor efficiency reduction and mechanical thermal expansion on transmission accuracy under high-temperature environments. It also has over-limit alarm and shutdown protection functions, realizing fully automated, high-precision, and high-safety control of the high-temperature superconducting cable wiring and transmission process.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The high-temperature resistant superconducting cable and its intelligent cable connection transmission device involved in the present invention are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] Please see Figures 1-4 The high-temperature resistant superconducting cable and its intelligent cable connection conveying device shown include a main unit housing 1, an upper conveying pressure roller assembly 2, a pressure roller pressure adjustment assembly 3, a lower conveying pressure roller assembly 4, a servo motor assembly 5, and a control component 6;
[0030] The main unit housing 1 serves as the mounting base for the entire device and is made of high-temperature resistant metal material, with internal space for accommodating various components.
[0031] The upper conveying pressure roller assembly 2 and the lower conveying pressure roller assembly 4 are arranged opposite each other on the same side of the main unit housing 1, forming a conveying channel for superconducting cables to pass through. The upper conveying pressure roller assembly 2 is equipped with a pressure roller pressure regulating assembly 3, which is used to regulate the pressure of the upper conveying pressure roller on the cable, thereby adapting to superconducting cables of different diameters or materials, ensuring stable conveying and not damaging the cable.
[0032] The servo motor assembly 5 is installed on the other side of the main unit housing 1 and is connected to the upper conveying pressure roller assembly 2 or the lower conveying pressure roller assembly 4 for transmission. In this embodiment, the output shaft of the servo motor assembly 5 is directly connected to the rotating shaft of the upper conveying pressure roller assembly 2 through a coupling or a pulley. At the same time, the upper conveying pressure roller assembly 2 and the lower conveying pressure roller assembly 4 are connected by a gear set for transmission, so that when the servo motor assembly 5 drives the upper conveying pressure roller to rotate, the lower conveying pressure roller rotates synchronously in the opposite direction, thereby realizing the stable clamping and bidirectional transmission of the superconducting cable.
[0033] It should be noted that the various components involved in this embodiment, including but not limited to the main unit housing 1, the upper conveying pressure roller assembly 2, the pressure roller pressure adjustment assembly 3, the lower conveying pressure roller assembly 4, the servo motor assembly 5, the gear set, and the external housing and mounting structure of the control component 6, are all conventional mechanical and electrical components in the art. Their specific materials, dimensions, models, connection methods (such as welding, bolt fixing, key connection, etc.), as well as the number of teeth and module of the gear set, are all existing technologies that can be directly selected by those skilled in the art based on actual application requirements or determined through limited experiments.
[0034] The control unit 6 is located on the outer wall of the main unit housing 1 and is used to receive external commands and control the start, stop, speed and direction of the servo motor assembly 5. The control unit 6 has built-in multi-source physical quantity real-time acquisition module, data normalization preprocessing module, conveying characteristic parameter extraction module, initial conveying parameter generation module, clamping pressure real-time correction module, conveying displacement PID correction module, preset database Euclidean distance comparison and confirmation module, speed inversion and mechanical execution output module and real-time closed-loop feedback module.
[0035] The multi-source physical quantity real-time acquisition module serves as the starting point for the control logic, acquiring real-time physical quantities associated with the conveying equipment. The acquired parameters include:
[0036] Actual clamping pressure of the pressure roller The pressure data is collected by the pressure sensor configured inside the pressure roller pressure regulating assembly 3, and the unit is Newton (N).

[0041] To eliminate the influence of different physical dimensions on subsequent algorithm fusion calculations, the data normalization preprocessing module performs minimum-maximum normalization on all acquired parameters, mapping the original physical quantities to dimensionless values in the interval [0, 1]. The normalization algorithm formula is as follows:

[0051] After the above calculations, a set of dimensionless parameters is output. , as input to the feature parameter extraction module;
[0052] The conveying feature parameter extraction module progressively uses the normalized parameters of the data normalization preprocessing module to extract core feature coefficients that reflect the characteristics of mechanical clamping and high-temperature working conditions.
[0053] Clamping adaptation coefficient The coefficient is used to characterize the matching degree between the current clamping pressure and the cable diameter, preventing excessive clamping force from damaging the cable or insufficient clamping force from causing slippage during transport; its calculation formula is:
[0054] ;
[0055] In the formula: molecule Increase or denominator Decrease all lead to Both of these will lead to an increase, indicating that the pressure per unit diameter is too high. It should be noted that... The normal operating range is [0.2, 0.8]; when the calculated value falls outside this range, the control component 6 will trigger an alarm to prompt the operator to adjust the pressure regulating component 3;
[0056] Temperature influence coefficient The coefficient is calculated to compensate for the decrease in output efficiency of servo motor component 5 and the impact of thermal expansion of mechanical structure on rotational speed under high-temperature conditions; its calculation formula is as follows:
[0057] ;
[0058] In the formula: This is the temperature attenuation coefficient; it was obtained through high-temperature performance aging tests on servo motor component 5. The specific test method involved testing the attenuation rate of the motor output torque-speed curve at room temperature (25℃) and different high-temperature points (50℃, 100℃, 150℃, 200℃) in a constant temperature chamber, and obtaining the coefficient from the slope of the linear regression fitting. In this embodiment, The value range is [0.05, 0.15];
[0059] Based on the above formula and coefficient range, The calculation result is located in the interval [0.85, 0.95], and is represented as a dimensionless attenuation gain coefficient;

[0061] ;
[0062] In the formula: This is the preset reference normalized rotational speed; this value is specified by default by the preset database based on the currently selected high-temperature superconducting cable type (such as Bi-2223 first-generation wire or YBCO second-generation tape), and the value range is [0.1, 0.9].
[0063] To eliminate the nonlinear loss of rotational speed and friction caused by clamping pressure fluctuations (due to mechanical vibration or wire diameter tolerances), the real-time clamping pressure correction module performs the first correction; the correction formula is:
[0064] ;
[0065] In the formula: The dimensionless target rotational speed after the first correction;
[0066] The target clamping pressure normalized value is obtained from a preset database based on the current cable diameter, and its calculation logic is as follows: ;
[0067] This is the normalized value of the current actual clamping pressure;
[0068] This is a pressure correction factor, obtained through a pressure-speed response test of the pressure roller. The specific method involves fixing the cable, changing the pressure, and recording the steady-state speed change rate. The value is the average of the slopes of multiple experimental groups. In this embodiment... ;
[0069] Correction logic:
[0070] when (Insufficient pressure, easy to slip) (Reduce engine speed to reduce the risk of slippage);
[0071] when (Excessive pressure may damage the cable) (Increase the rotation speed appropriately and shorten the cable pressure time);
[0072] when (No correction);
[0073] First correction validity determination: Set the first correction threshold This threshold is calibrated by a preset database based on the equipment's factory precision (allowing for speed fluctuations of 5%); if If the correction is deemed valid, output [the corrective action]. If the deviation exceeds the limit, it is considered that the sensor data is abnormal or mechanically stuck, and the control unit 6 will execute a command to re-acquire the data. The calculation is iterated until convergence or an alarm is triggered; if the limit is exceeded three times consecutively, an alarm will be triggered and the machine will be shut down.
[0074] To eliminate cumulative displacement errors during cable transport and ensure that the connectors arrive at the workstation precisely, a PID correction module for transport displacement is used progressively. A second correction is made by introducing a positional PID control algorithm; the correction formula is:
[0075] ;
[0076] Among them, error amount ; and All have been based on the maximum travel of the equipment. Normalize to [0,1];
[0077] Discretization implementation (sampling period) ):
[0078] ;
[0079] Coefficient values: All were tuned through step response testing;
[0080] Second correction validity determination: Set a second correction threshold ,like Then output Otherwise, continue iterating until three consecutive over-limit alarms trigger a shutdown.
[0081] In the formula: The second revised dimensionless target rotational speed;
[0082] The normalized target delivery displacement is preset by the spatial coordinates of the wiring station;
[0083] , , These are the proportional, integral, and derivative coefficients, respectively. This set of coefficients was obtained through fitting the displacement closed-loop step response test of this conveying equipment (tuned using the Ziegler-Nichols method), and their value ranges are as follows: ;
[0084] The sampling control period is set to [period] in this embodiment. (In discrete implementation, the integral term is accumulated.) Differential terms adopt ;
[0085] Second correction validity determination: Set a second correction threshold: This threshold is calibrated by a preset database and represents the maximum allowable relative displacement error; if the displacement error is fed back in real time... If the correction is deemed valid, output [the corrective action]. ;
[0086] To eliminate systematic, slowly varying errors such as mechanical wear and sensor zero-point drift after long-term equipment operation, a pre-set database Euclidean distance comparison and verification module is used for final verification and correction; the spatial distance between the real-time operating feature vector and the ideal standard vector in the database is calculated. :
[0087] ;
[0088] In the formula: This is a pre-defined database containing standard multidimensional parameter vectors corresponding to the current operating conditions (wire diameter, temperature range); this database was established through full-condition calibration tests before the equipment leaves the factory.
[0089] The threshold for database comparison is set to a value of [value]. This threshold is determined by the maximum permissible Mahalanobis distance during the equipment's factory calibration test;
[0090] Final revised rules:
[0091] like This indicates that the current operating status is highly consistent with the factory standard status, directly confirming the final normalized speed. ;
[0092] like This indicates the presence of a systematic bias. To prevent sudden parameter changes from causing transmission jitter, a weighted averaging strategy is used for smoothing correction. ;
[0093] The results obtained after the above three levels of correction To normalize the dimensionless values, the speed inversion and mechanical execution output module needs to invert the values into the actual physical speed commands that the servo motor component 5 can execute; the inversion formula is the inverse operation of the normalization algorithm:
[0094] ;
[0095] Substitute the preset extreme value Calculate the actual motor speed The unit is r / min; the speed inversion and mechanical execution output module sends this precise value to the driver of the servo motor assembly 5 via the fieldbus, driving the servo motor assembly 5 to operate;
[0096] During operation, the real-time closed-loop feedback module of this equipment executes the above-mentioned multi-source physical quantity real-time acquisition module, data normalization preprocessing module, conveying characteristic parameter extraction module, initial conveying parameter generation module, clamping pressure real-time correction module, conveying displacement PID correction module, preset database Euclidean distance comparison and confirmation module, and speed inversion and mechanical execution output module in 10ms cycles. Each cycle is calculated and corrected three times based on the latest sensor data, forming a millisecond-level precise control closed loop for the cable conveying process, ensuring that the high-temperature superconducting cable is subjected to uniform force and accurate positioning throughout the wiring process.
[0097] In summary, by deeply coupling the conveying equipment with the intelligent control algorithm, this invention not only provides the hardware foundation, but also solves the problems of difficult conveying parameter tuning and poor adaptability to changes in operating conditions in the prior art through specific normalization preprocessing, feature coefficient extraction, and three-level progressive correction confirmation logic.
