Description

Technical Field

[0001] The present application relates to the field of cable processing technology, and in particular to a method and system for stabilizing the outer diameter of a data cable conductor. Background Art

[0002] As the requirements for data transmission stability and speed increase, the number of cables in the data cable conductor increases, and multiple cables need to be twisted.

[0003] In the related art, cables are twisted by a twisting machine to combine multiple cables of different types into one to obtain a data cable. The conductor outer diameter and resistance of the data cable are important parameters that affect signal attenuation. Especially for multi-core cables, the consistency of the conductor is the key to determining the signal transmission effect. Although the process parameters of the process cable conductors on the same twisting equipment are the same, it is difficult to know the inconsistency of the wire materials caused by some processing processes.

[0004] Regarding the above-mentioned related technologies, when the wire material is inconsistent, it is easy to have an adverse effect on the signal transmission reliability of the cable conductor, which needs to be improved. Summary of the invention

[0005] In order to solve the above-mentioned problems in the related art, the present application provides a method and system for stabilizing the outer diameter of a data cable conductor.

[0006] In a first aspect, the present application provides a method for stabilizing the outer diameter of a data cable conductor, which adopts the following technical solution:

[0007] A method for stabilizing the outer diameter of a data cable conductor, comprising:

[0008] Instructing a preset laser diameter measuring instrument to continuously detect the outer diameter of the data cable conductor when it is twisted, so as to determine the conductor twisted outer diameter parameters, wherein the twisted outer diameter parameters include the twisted outer diameter value and the outer diameter detection time;

[0009] Generate an outer diameter change line graph based on the twisted outer diameter value and the outer diameter detection time, and compare the outer diameter change line graph with a preset allowable outer diameter interval value;

[0010] When the outer diameter variation line graph exceeds the allowable outer diameter interval value, an analysis is performed based on the outer diameter detection time to determine the unstable position of the cable corresponding to the line graph;

[0011] Calculate the negative gain value of the twisted outer diameter value corresponding to the unstable position of the cable according to the preset negative gain value calculation strategy;

[0012] When the negative gain value is greater than a preset upper limit negative gain value, a preset wire twisting processing device is instructed to re-twist the data cable conductors.

[0013] By adopting the above technical solution, a laser diameter gauge with high measurement accuracy is used to detect the outer diameter of the cable conductor, and a corresponding outer diameter change line graph is generated for outer diameter analysis, so that the cable conductor that causes a large negative gain value of the outer diameter is re-twisted, so that the produced data cable has better outer diameter consistency and is not easily affected by the data signal transmission effect.

[0014] Optionally, the continuous detection of the outer diameter of the data cable conductor when it is twisted includes:

[0015] Collect the vibration frequency of the laser diameter gauge probe during the stranding process;

[0016] When the vibration frequency of the probe is greater than the preset allowable frequency, the cable processing parameters of the stranding processing equipment are collected, and the cable processing parameters include the number of core wires processed and the stranding speed;

[0017] Matching is performed according to the number of core wires processed and the preset basic processing speed matching database to determine the stranding speed range corresponding to the number of core wires processed;

[0018] Analyze the upper and lower processing speed limits of the stranding speed range, and compare and analyze them with the stranding speed to determine the range value that can be adjusted downward;

[0019] Calculating based on the adjustable interval value and the preset step-by-step decreasing ratio parameter to determine the adjusted strand processing parameters, the strand processing parameters including the processing speed and the corresponding number of reductions;

[0020] Instruct the preset stranding wire processing equipment to adjust the stranding wire speed according to the number of downward adjustments and the processing speed.

[0021] By adopting the above technical solution, the vibration frequency of the laser diameter gauge probe is detected, and the vibration impact of the stranded wire processing equipment on the laser diameter gauge is analyzed, so that the adjustable processing parameters can be adjusted downward. While maintaining good processing efficiency, the probability of errors in laser diameter gauge detection can be reduced, which helps to improve the accuracy of the outer diameter value of the cable conductor.

[0022] Optionally, when adjusting the stranding speed, it also includes:

[0023] Collect the vibration amplitude of the stranding equipment for analysis to determine the vibration amplitude change rate;

[0024] Conduct a trend analysis on the vibration amplitude change rate to determine the vibration amplitude change trend;

[0025] If the vibration amplitude change trend is consistent with the preset downward change trend, an adjustment hold prompt will be issued;

[0026] When the probe micro-motion amplitude falls within the preset stable jitter amplitude range, the stranding speed is marked to determine the reference stranding speed and a calibration prompt is issued;

[0027] Adjacent strand speeds are adjusted based on calibration prompts using a preset strand speed callback method to determine the optimum strand speed.

[0028] By adopting the above technical solution, when adjusting the stranding speed of the equipment, the stranding speed is adjusted according to the change trend of the vibration amplitude of the stranding processing equipment, so that after the initial adjustment of the stranding speed, the stranding speed can be feedback-adjusted again to select the optimal stranding speed, so that the stranding processing equipment can maintain a good stranding speed without affecting the detection accuracy of the laser diameter gauge.

[0029] Optionally, the stranding speed callback method includes:

[0030] Matching is performed according to the reference stranding speed and the preset dynamic callback database to determine the dynamic callback speed value that is slightly adjusted in accordance with the reference stranding speed;

[0031] Instruct the preset stranding wire processing equipment to increase the reference stranding wire speed according to the dynamic callback speed value, and monitor the probe micro-motion amplitude;

[0032] If the probe micro-motion amplitude is smaller than the preset stable jitter amplitude range, the stranding speed is increased based on the dynamic callback speed value, and the upper limit value of the stable jitter amplitude range is analyzed;

[0033] Calculate the upper limit of the probe micro-motion amplitude and the stable jitter amplitude range to determine the over-limit interval value;

[0034] When the over-limit interval value is equal to the preset approach interval value, the preset stranding wire processing equipment is instructed to stop adjusting the stranding wire speed, and the stranding wire speed is marked as the optimal stranding wire speed.

[0035] By adopting the above technical scheme, corresponding matching is performed according to the benchmark stranding speed to match the corresponding dynamic callback speed value for adjustment, and further analysis is performed on whether the probe micro-motion amplitude is still within the stable jitter amplitude range during the callback process, thereby reducing the probability of reducing the stranding speed too much in the process of lowering the stranding speed, so that the stranding processing equipment can maintain the stranding processing efficiency while not causing excessive vibration of the stranding processing equipment due to the fast stranding speed, thereby reducing the probability of the laser diameter gauge being affected by vibration and affecting the detection accuracy.

[0036] Optionally, when determining the optimal stranding speed, the following is also included:

[0037] Compare and mark according to the number of core wires processed to identify the same type of parameter stranding wire processing equipment with the same number of core wires processed;

[0038] Based on the association of similar parameter stranding processing equipment, the operation signals of the associated similar parameter stranding processing equipment during stranding processing are collected;

[0039] Based on the operation signal indicating the same parameter stranding processing equipment, the stranding speed is adjusted according to the optimal stranding speed.

[0040] By adopting the above technical solution, after adjusting and marking the optimal stranding speed, by analyzing the stranding processing equipment with similar parameters and the same number of core wires processed, and adjusting the stranding speed accordingly, multiple stranding processing equipment can maintain good consistency of processed products, so that data cables of the same specifications have similar signal transmission performance.

[0041] Optionally, the negative gain value calculation strategy is calculated using the following formula:

[0042] λ=α1·Δd1+α2·Δd2+α i ·Δd i ,

[0043] Δd i =(d a -d i ),

[0044] Among them, λ is the negative gain value, α1 is the first unstable position detected, and α i The i-th unstable position, Δd i It represents the difference between the twisted outer diameter value at the i-th unstable position and the allowable outer diameter interval value, d a Indicates the allowable outer diameter range, d i Indicates the twisted outer diameter value corresponding to the i-th unstable position of the cable.

[0045] By adopting the above technical solution, the negative gain values ​​caused by multiple unstable positions are calculated, so as to analyze whether the overall cable conductor has poor transmission performance when transmitting data signals, which helps to timely adjust the twisting of cable conductors with larger influence weight values, so that the cable conductors maintain good outer diameter consistency.

[0046] Optionally, when instructing a preset twisting wire processing device to re-twist the conductors of the data cable, it also includes:

[0047] Collect the core wire material of the data cable conductor for analysis to determine the core wire material category;

[0048] Compare the core wire material category with the preset repeatable twisted material table to determine whether the core wire material category corresponds to the material type in the repeatable twisted material table;

[0049] If they do not correspond, the outside diameter change difference is determined by calculation based on the turning point of the broken line and the allowable change range;

[0050] Match the difference influence coefficient corresponding to the outer diameter change difference in the preset outer diameter influence coefficient database;

[0051] When the difference influence coefficient is greater than the preset allowable influence coefficient, the cable conductor is marked as an unqualified conductor.

[0052] By adopting the above technical solution, the core wire material of the data cable conductor is analyzed to screen out the core wire material that can be re-twisted, and the cable conductors with unstable outer diameter positions are re-twisted. At the same time, the cable conductors that have a greater impact and are not convenient for re-twisting are marked, so as to identify unqualified cable conductor products.

[0053] Optionally, when generating a line graph of outer diameter variation, include:

[0054] Perform line overlap analysis based on the outer diameter variation line graph and mark the overlapping line segments;

[0055] If the twisted outer diameter value corresponding to the overlapping broken line segment is greater than the preset allowable outer diameter interval value, the outer diameter detection time corresponding to the overlapping broken line segment is extended by a preset unit time length to determine the optimized broken line segment;

[0056] A polyline overlap analysis is performed on the optimized polyline segments to determine the number of overlapping discounted segments, until the number of overlapping polyline segments is less than the preset number of non-overlapping discounted segments.

[0057] By adopting the above technical solution, the overlapping broken line segments of the outer diameter change line graph are adjusted so that the overlapping broken line segments can be unfolded and form optimized broken line segments with clear broken lines, thereby improving the broken line clarity of the outer diameter change line graph and helping to reduce the probability of unclear overlapping line segments when comparing the outer diameter values ​​with the allowable variation range.

[0058] In a second aspect, the present application provides a data cable conductor outer diameter stabilization system, which adopts the following technical solution:

[0059] A data cable conductor outer diameter stabilization system, comprising:

[0060] The acquisition and analysis module instructs a preset laser diameter measuring instrument to acquire the outer diameter value of the twisted conductor of the data cable conductor during the twisting process to determine the conductor twisting outer diameter parameter, wherein the conductor twisting outer diameter parameter includes the twisting outer diameter value and the acquisition time;

[0061] The outer diameter analysis module draws line segments according to the twisted outer diameter value and the acquisition time to determine the outer diameter change line graph;

[0062] Compare the turning points of the outer diameter change line graph with the preset allowable change range, and issue an unstable prompt when the turning point of the line is outside the preset allowable change range;

[0063] Mark turning points based on unstable cues to determine the location of unstable outer diameter;

[0064] The outer diameter stabilization module indicates that the preset stranding equipment performs re-twisting based on the unstable outer diameter position;

[0065] A memory for storing a program of any one of the methods for stabilizing the outer diameter of a conductor of a data cable;

[0066] The program in the memory can be loaded and executed by the processor to implement any one of the methods for stabilizing the outer diameter of a data cable conductor.

[0067] By adopting the above technical solution, the outer diameter value of the twisted conductor is measured with high precision, and the twisted conductor is continuously monitored during the twisting process to form an intuitive outer diameter change line graph for analysis. At the same time, the position where the outer diameter is unstable is re-twisted, so that the data cable conductors twisted by the twisting processing equipment have good consistency.

[0068] In summary, the present application includes at least one of the following beneficial technical effects:

[0069] 1. Use a laser diameter gauge with high measurement accuracy to detect the outer diameter of the cable conductor, and generate a corresponding outer diameter change line graph for outer diameter analysis, so as to re-twist the cable conductors with large negative gain values ​​on the outer diameter, so that the produced data cables have better outer diameter consistency and are not likely to affect the data signal transmission effect;

[0070] 2. Detect the vibration frequency of the laser diameter gauge probe and analyze the vibration effect of the stranded wire processing equipment on the laser diameter gauge, so as to adjust the processing parameters downward, which can maintain good processing efficiency while reducing the probability of errors in laser diameter gauge detection, and help improve the accuracy of the outer diameter value of the cable conductor;

[0071] 3. Match the number of new core wires processed during the twisting process of the data cable and the twisting speed range during the twisting process, and analyze the twisting speed interval value that can be adjusted down, so as to adjust the twisting speed accordingly to reduce the vibration impact caused by the faster twisting speed, thereby reducing the micro-motion amplitude of the probe of the laser diameter gauge.

[0079] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-7 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0080] The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0081] The embodiment of the present application discloses a method for stabilizing the outer diameter of a data cable conductor. The outer diameter of a twisted conductor of a data cable conductor is monitored during a twisting process by a high-precision laser diameter measuring instrument, and a line graph is drawn based on the monitored outer diameter parameters of the twisted conductor, so as to analyze whether the outer diameter change of the twisted conductor is unstable, and mark the position where the outer diameter of the conductor exceeds the allowable variation range, so as to perform corresponding re-twisting adjustment, so that the processed data cable conductor has better consistency.

[0082] Reference Figure 1 The method flow of the data cable conductor outer diameter stabilization method includes the following steps:

[0083] Step S100: instructing a preset laser diameter measuring instrument to continuously detect the outer diameter of the data cable conductor when it is twisted, so as to determine the conductor twisted outer diameter parameters, wherein the twisted outer diameter parameters include the twisted outer diameter value and the outer diameter detection time;

[0084] The laser diameter gauge can detect the outer diameter of the stranded conductor and collect the outer diameter value of the stranded conductor, and define it as the outer diameter value of the stranded conductor. The time of detecting the outer diameter value of the stranded conductor is recorded to form the conductor stranding outer diameter parameter.

[0085] Step S101: generating an outer diameter variation line graph based on the twisted outer diameter value and the outer diameter detection time, and comparing the outer diameter variation line graph with a preset allowable outer diameter interval value;

[0086] After collecting the conductor twist outer diameter parameters, the conductor twist outer diameter parameters are input into a preset automatic drawing model to generate a line graph of detection time-twisted conductor outer diameter value. The line graph is defined as an outer diameter change line graph for easy call in subsequent further analysis.

[0087] The allowable variation range is the deviation range of the conductor outer diameter value set by the staff according to the actual situation. The conductor outer diameter within this range has better signal transmission efficiency and lower signal attenuation. By comparing and analyzing the different inflection points in the broken line graph, it can be analyzed whether the outer diameter of the conductor exceeds the allowable variation range during the stranding process, and an unstable prompt signal will be issued when the turning point of the broken line exceeds the allowable variation range.

[0088] Step S102: when the outer diameter variation line graph exceeds the allowable outer diameter interval value, an analysis is performed according to the outer diameter detection time to determine the unstable position of the cable corresponding to the line graph;

[0089] When the outer diameter change line graph exceeds the allowable outer diameter interval value, it means that the twisted outer diameter value corresponding to the broken line on the outer diameter change line graph exceeds the set allowable interval value, and the outer diameter consistency of the cable conductor is poor at the unstable position. The axis corresponding to the outer diameter detection time is marked and defined as the cable unstable position time. By searching based on the unstable cable position time and the length of the cable conductor, the position of the unstable outer diameter on the cable conductor length can be found, and this position is defined as the cable unstable position.

[0090] Step S103: Calculate the negative gain value of the twisted outer diameter value corresponding to the unstable position of the cable according to a preset negative gain value calculation strategy;

[0091] The negative gain value calculation strategy is a formula used to calculate the negative gain of the twisted outer diameter value. The negative gain value indicates the negative impact value caused by the outer diameter consistency of the cable after twisting not meeting the requirements. The specific negative gain value calculation strategy uses the following formula for calculation:

[0092] λ=α1·Δd1+α2·Δd2+α i ·Δd i ,

[0093] Δd i =(d a -d i ),

[0094] Among them, λ is the negative gain value, α1 is the first unstable position detected, and α iThe i-th unstable position, Δd i It represents the difference between the twisted outer diameter value at the i-th unstable position and the allowable outer diameter interval value, d a Indicates the allowable outer diameter range, d i It indicates the twisted outer diameter value corresponding to the i-th unstable position of the cable. It should be noted that the larger the negative gain value, the worse the data transmission effect of the cable conductor after twisting, and vice versa.

[0095] Step S104: when the negative gain value is greater than a preset upper limit negative gain value, instruct a preset twisting wire processing device to re-twist the data cable conductors.

[0096] The upper limit negative gain value indicates the maximum negative gain value when good data transmission efficiency can be maintained. When the calculated negative gain value exceeds the upper limit negative gain value, it indicates that the twisted cable as a whole has many unstable cable positions, which makes the cable not have good data transmission efficiency. At this time, in order to keep the data cable able to meet the good data transmission requirements, the data cable conductor needs to be re-twisted. Then the cable processing equipment is controlled to rotate in the opposite direction and untwist the twisted single cable, and then re-twist it to change the twisted outer diameter value of the cable conductor. Usually, the outer diameter value generated when the cable conductor is twisted changes little. When re-twisting, the influence of the outer diameter difference of the cable conductor can be better corrected.

[0097] Reference Figure 2 , the continuous detection of the outer diameter of the data cable conductor when it is twisted includes:

[0098] Step S200: collecting the vibration frequency of the probe of the laser diameter measuring instrument during the processing of the stranded wire processing equipment;

[0099] Step S201: when the vibration frequency of the probe is greater than the preset allowable frequency, the cable processing parameters of the stranding processing equipment are collected, and the cable processing parameters include the number of core wires processed and the stranding speed;

[0100] The allowable frequency is the vibration frequency of the stranding processing equipment pre-set by the staff, indicating that the effective detection of the laser diameter gauge is not easily affected under this vibration frequency. By pre-installing a vibration frequency detector on the laser diameter gauge and allowing the vibration frequency detector to detect the probe, by comparing the vibration frequency with the allowable frequency, when the vibration frequency is greater than the allowable frequency, it means that the stranding processing equipment has a certain impact on the detection accuracy of the laser diameter gauge. At this time, the cable processing parameters composed of the number of core wires processed and the stranding speed are collected for further analysis.

[0101] Step S202: matching the number of core wires to be processed and a preset basic processing speed matching database to determine a stranding speed range corresponding to the number of core wires to be processed;

[0102] The stranding speed range is the speed value range that can stably strand the wires when stranding the wires according to the number of core wires processed. Different stranding speed ranges are used for stranding wires with different numbers of core wires processed. By pre-establishing a stranding speed range matching database, different core wire processing numbers are stored in the database, and the associated stranding speed ranges are stored. When the core wire processing speed is input, the corresponding stranding speed range can be matched and output.

[0103] Step S203: analyzing the upper processing speed and the lower processing speed of the stranding speed range, and comparing and analyzing them with the stranding speed to determine a downwardly adjustable interval value;

[0104] By analyzing the upper and lower limits of the stranding speed range, the upper limit is defined as the upper processing speed, and the lower limit is defined as the lower processing speed. By comparing the stranding speed of the current stranding processing equipment collected with the upper and lower processing speeds, it can be learned that the current stranding speed is adjusted down to an interval value between the lower line processing speed, and this interval value is defined as the downward adjustable interval value.

[0105] Step S204: performing calculation based on the downwardly adjustable interval value and the preset step-by-step decreasing ratio parameter to determine the downwardly adjusted stranded wire processing parameters, the stranded wire processing parameters including the processing speed and the corresponding downward adjustment times;

[0106] The gradually decreasing ratio parameter indicates the ratio calculated each time the stranding speed is lowered, wherein the ratio of each decrease will gradually decrease. For example, when the gradually decreasing ratio parameter is 0.3 for the first decrease, 0.25 for the second, and 0.2 for the third. By gradually decreasing, the stranding speed is not easily lowered too much, thereby maintaining a high processing speed while reducing the vibration effect on the laser diameter gauge. The gradually decreasing ratio parameter is pre-set by the staff, and the corresponding number of decreases and the reduced processing speed can be obtained by calculating the stranding speed and the stranding processing parameters.

[0107] Step S205: instructing the preset wire stranding processing equipment to adjust the wire stranding speed according to the number of downward adjustments and the processing speed.

[0108] After knowing the number of downward adjustments and the processing speed, the wire stranding processing equipment is instructed to make adjustments so that the wire stranding speed is gradually reduced within the downward adjustable range, thereby gradually reducing the vibration caused by the wire stranding processing equipment to no effect.

[0109] Reference Figure 3 , when adjusting the stranding speed, it also includes:

[0110] Step S300: collecting the vibration amplitude of the stranding processing equipment for analysis to determine the vibration amplitude change rate;

[0111] By calculating the vibration frequency generated by the stranding processing equipment within a set unit time, the amplitude change rate of the vibration frequency can be obtained, and this change rate is defined as the vibration amplitude change rate for further analysis and call later.

[0112] Step S301: performing a change trend analysis on the vibration amplitude change rate to determine the vibration amplitude change trend;

[0113] By analyzing the rise and fall of the vibration amplitude change rate over a continuous period of multiple unit times, the rising or falling trend of the vibration amplitude change rate can be determined.

[0114] Step S302: If the vibration amplitude change trend is consistent with the preset downward change trend, an adjustment maintenance prompt is issued;

[0115] By analyzing whether the vibration amplitude change trend is consistent with the downward trend, that is, whether the vibration amplitude change rate is gradually decreasing, when it is consistent with the downward trend, it means that by gradually reducing the stranding speed of the stranding processing equipment, the vibration can be effectively reduced. At this time, an adjustment maintenance prompt signal is issued to continue to adjust to the appropriate stranding speed.

[0116] Step S303: when the probe micro-motion amplitude falls within the preset stable jitter amplitude range, the stranding speed is marked to determine the reference stranding speed and a calibration prompt is issued;

[0117] The probe micromotion amplitude is the vibration frequency of the probe used by the laser diameter gauge to detect the outer diameter of the conductor when it vibrates, and the stable jitter amplitude range is the jitter range in which the laser diameter gauge can maintain accurate detection when affected by vibration. By comparing the probe micromotion amplitude with the preset stable micromotion amplitude range during the continuous adjustment of the stranding speed, it can be known whether the laser diameter gauge can stably detect the outer diameter of the conductor at this time. When the micromotion amplitude of the micromotion probe falls within the preset stable jitter amplitude range, it means that the adjustment of the stranding processing equipment is completed. At this time, the stranding speed is marked and recorded, and the stranding speed is defined as the reference stranding speed. At the same time, a calibration prompt signal is issued to make fine adjustments and calibrations to the reference foot wire speed.

[0118] Step S304: adjusting the speed of adjacent strands using a preset strand speed callback method based on the calibration prompt to determine an optimal strand speed.

[0119] The stranding speed callback method is a method for fine-tuning and calibrating the reference stranding speed and re-determining the optimal stranding speed, which will be further described in detail in the subsequent steps.

[0120] Reference Figure 4, the stranding speed callback methods include:

[0121] Step S400: matching the reference stranding speed with a preset dynamic callback database to determine a dynamic callback speed value that is slightly adjusted according to the reference stranding speed;

[0122] The dynamic callback database is a pre-established dynamic callback speed value matching database, which stores different reference stranding speeds and dynamic callback speed values ​​corresponding to the dynamic callback speed values. When the corresponding reference stranding speed is input, the dynamic callback speed value associated with the output can be automatically matched. The dynamic callback speed value is an adjustment value for increasing or decreasing the stranding speed based on the reference stranding speed. During the callback process, the probe micro-motion amplitude can be analyzed again to see if it is within the preset stable jitter amplitude range.

[0123] Among them, the reason why different reference stranding speeds have different dynamic callback speed values ​​is that the closer the reference stranding speed is to the lower limit processing speed, the smaller the adjusted stranding speed needs to be kept within the numerical range when performing dynamic callback, so that over-adjustment is not likely to occur when calibrating the callback stranding speed.

[0124] Step S401: instructing a preset stranding wire processing device to increase the reference stranding wire speed according to the dynamic callback speed value, and monitoring the probe micro-motion amplitude;

[0125] After matching the corresponding dynamic callback speed value, the stranding processing equipment is instructed to call back the stranding speed according to the dynamic callback speed value, and the probe micro-motion amplitude is monitored at the same time, so as to know the effect of the adjustment in time later.

[0126] Step S402: if the probe micro-motion amplitude is smaller than the preset stable jitter amplitude range, the stranding speed is increased based on the dynamic callback speed value, and the upper limit value of the stable jitter amplitude range is analyzed;

[0127] When the probe micro-motion amplitude is smaller than the stable jitter amplitude range, it means that when the wire stranding operation is carried out at the wire stranding speed, the vibration effect is reduced to the point where it will not affect the laser diameter gauge, but the wire stranding speed is greatly reduced, which is not conducive to increasing the wire stranding processing speed. At this time, the wire stranding speed is increased according to the dynamic callback speed value, and the upper limit value of the stable jitter amplitude range is further analyzed for the convenience of subsequent further adjustments.

[0128] Step S403: Calculate the upper limit of the probe micro-motion amplitude and the stable jitter amplitude range to determine the over-limit interval value;

[0129] By subtracting the value corresponding to the probe micro-motion amplitude from the upper limit value of the stable jitter amplitude range, the calculated value is defined as the over-limit interval value. The over-limit interval value indicates whether the probe micro-motion amplitude exceeds the stable jitter amplitude range during the process of increasing the stranding speed, so as to stop the adjustment in time.

[0130] Step S404: when the over-limit interval value is equal to the preset close interval value, the preset stranding wire processing equipment is instructed to stop adjusting the stranding wire speed, and the stranding wire speed is marked as the optimal stranding wire speed.

[0131] The close interval value represents the numerical range interval adjacent to the out-of-limit interval value, and is intercepted according to the preset ratio based on the range of the out-of-limit interval value. For example, if the value of the stable jitter amplitude range is 10-50, and the value of the probe micro-motion amplitude is 45, then the out-of-limit interval value is 45-50. When the out-of-limit interval value is compared with the close interval value, if the out-of-limit interval value and the close interval value are equal, it means that the stranding speed cannot be further adjusted at this time, which may easily affect the detection of the laser diameter gauge. In this case, the adjustment of the stranding speed is stopped, and the current stranding speed is defined as the optimal stranding speed.

[0132] Reference Figure 5 , when determining the optimal stranding speed, it also includes:

[0133] Step S500: comparing according to the number of processed core wires, marking to determine the same type of parameter stranding wire processing equipment with the same number of processed core wires;

[0134] By marking the stranded wire processing equipment with the same number of core wires, and defining them as stranded wire processing equipment with the same parameters, it is convenient to call them for further analysis later.

[0135] Step S501: Associating wire stranding processing equipment with similar parameters, and collecting operation signals of the associated wire stranding processing equipment with similar parameters when performing wire stranding processing;

[0136] Since the data cable conductors processed by the same parameter twisted wire processing equipment have the same specification parameter requirements, the corresponding twisted wire processing equipment needs to be processed according to the same parameters. At this time, the same parameter twisted wire processing equipment is associated to facilitate the subsequent same control. After associating the corresponding twisted wire processing equipment, it can be known which processing equipment is currently processing the twisted wire by collecting the operation signal.

[0137] Step S502: instructing the same-parameter stranding processing equipment to adjust the stranding speed according to the optimal stranding speed based on the operation signal.

[0138] By knowing the equipment that is about to perform corresponding wire stranding processing among multiple wire stranding processing equipment, and instructing these wire stranding processing equipment with similar parameters to adjust according to the optimal wire stranding speed, multiple wire stranding processing equipment can be quickly adjusted to the optimal processing state without the need for corresponding automatic adjustment, thereby maintaining the efficiency of effective wire stranding of cable conductors and will not affect the stable detection of the laser diameter gauge.

[0139] Reference Figure 6 , when instructing the preset twisting wire processing equipment to re-twist the data cable conductors, it also includes:

[0140] Step S600: collecting the core wire material of the data cable conductor for analysis to determine the type of the core wire material;

[0141] After detecting and marking the corresponding unstable outer diameter position, the type of the core wire material can be learned by collecting and analyzing the core wire material. Different types of core wire materials have different material types, which are defined as core wire material categories.

[0142] Step S601: comparing the core wire material category with a preset table of reproducible twisted materials to determine whether the core wire material category corresponds to the material type in the table of reproducible twisted materials;

[0143] The repeatable twisted material table is a pre-set material category database. Different core wire material categories are stored in the database and classified and stored according to different categories. When the core wire material category is input, the material type of the core wire material can be analyzed and found. The material types include repeatable twisted types and non-repeatable twisted types.

[0144] Step S602: If not, then calculate based on the turning point of the broken line and the allowable variation range to determine the outer diameter variation difference;

[0145] If the material type corresponds to a preset repeatable twisting type, a repeat twisting prompt signal is issued to control the stranding processing equipment to re-twist the unstable outer diameter position.

[0146] If they do not correspond, it means that the material of the core wire is not suitable for re-twisting. At this time, the difference between the value corresponding to the turning point of the broken line and the allowable variation range is calculated, and the difference is defined as the outer diameter variation difference, indicating that the outer diameter value at the unstable position of the outer diameter exceeds the allowable variation range.

[0147] Step S603: matching the difference influence coefficient corresponding to the outer diameter change difference in the preset outer diameter influence coefficient database;

[0148] When the outer diameter of the cable conductor exceeds the allowable variation difference, the signal transmission of the cable conductor has different effects, some of which are relatively low, and some are relatively high. The influence is related to the influence weight coefficient. The larger the influence weight coefficient, the higher the influence, and vice versa. The weight coefficient is defined as the outer diameter variation difference influence coefficient, which represents the influence coefficient value for the stability of data signal transmission of the conductor. By pre-establishing a stable influence weight database, different outer diameter variation difference influence coefficients are stored in the database, and the corresponding outer diameter variation difference is stored. When the variation difference is input, the outer diameter variation difference influence coefficient is automatically matched and output.

[0149] Step S604: When the difference influence coefficient is greater than the preset allowable influence coefficient, the cable conductor is marked as an unqualified conductor.

[0150] The qualified influence coefficient indicates that the outer diameter corresponding to the unstable outer diameter position of the twisted conductor can maintain the transmission of data signals. By comparing the outer diameter change difference influence coefficient with the pre-set qualified influence coefficient, when the outer diameter change difference influence coefficient is greater than the qualified influence coefficient, it means that the transmission efficiency of the cable conductor for data signals does not meet the requirements, the cable conductor is marked and defined as an unqualified conductor, so as to facilitate the subsequent recycling of the cable conductor.

[0151] Reference Figure 7 , when generating the outer diameter change line graph, include:

[0152] Step S700: performing overlapping analysis of broken lines according to the outer diameter variation broken line graph and marking overlapping broken line segments;

[0153] The outer diameter change line graph is formed by connecting multiple inflection points. When the acquisition speed is fast and the outer diameter cable conductor processing speed is slow, it is easy to cause the line segments of the outer diameter change line graph to overlap, which is not conducive to the comparison of the twisted outer diameter value and the allowable outer diameter interval value of the outer diameter change line graph. By comparing the outer diameter change line graph with the line segment, it can be found that there are overlapping line segments, and the line segment is defined as an overlapping line segment.

[0154] Step S701: if the twisted outer diameter value corresponding to the overlapping broken line segment is greater than the preset allowable outer diameter interval value, the outer diameter detection time corresponding to the overlapping broken line segment is extended by a preset unit time length to determine the optimized broken line segment;

[0155] By comparing the overlapping polyline segments with the allowed outer diameter interval values, the overlapping polyline segments can be known. By extending the corresponding positions of the overlapping polyline segments on the time axis according to the unit time length, that is, calculating and summing the corresponding time of the polyline segment's inflection points on the time axis, the position of the inflection points on the time axis is extended, thereby increasing the distance between two adjacent inflection points, making it less likely for the polyline segments with outer diameter changes to overlap, and the polyline segments obtained after the extension processing on the time axis are defined as optimized polyline segments. The unit time length is set by the staff according to actual needs, for example, two seconds or three seconds as the unit time length.

[0156] Step S702: performing a polyline overlap analysis on the optimized polyline segments to determine the number of overlapping discount segments, until the number of overlapping polyline segments is less than the preset number of non-overlapping discount line segments.

[0157] When there are many overlapping broken line segments in the outer diameter change broken line segment generation process, by performing broken line segment overlap analysis on the optimized broken line segment again, it can be known whether there is still broken line overlap. If so, the optimized broken line segment is continuously extended according to the set unit time length, and the number of overlapping broken line segments is analyzed. By comparing the number of overlapping broken line segments with the pre-set number of non-overlapping broken line segments, it can be known whether there are still overlapping broken line segments. If not, it means that no broken line segment adjustment is required. Among them, the number of non-overlapping broken line segments is one. When the number of overlapping broken line segments is less than the number of non-overlapping broken line segments, it means that there are no overlapping broken line segments.
