Description

Technical Field

[0001] This invention relates to the field of cable manufacturing technology, and in particular to a method and system for dynamic compensation of cable wrapping tape parameters. Background Technology

[0002] In the cable manufacturing process, the wrapping process of the wrapping tape around the cable core is a key step that determines the core performance of the cable terminal product. The stability and consistency of the wrapping quality directly affect the core indicators of the cable, such as insulation protection.

[0003] Current quality control technologies for cable wrapping tape generally suffer from significant bottlenecks: Firstly, existing technologies typically only passively address deviations that occur during the wrapping process, neglecting to assess the subsequent winding trend. This results in adjustments lagging behind actual operating condition fluctuations, making it difficult to meet the stringent requirements of high-speed continuous cable production. Secondly, insufficient environmental adaptability is a concern, as the wrapping tape material is susceptible to environmental factors. Temperature fluctuations during cable wrapping can cause thermal expansion and contraction of the tape, leading to unexpected deviations in the tape's fit with the cable, significantly reducing the process stability under complex conditions. Thirdly, adjustments to wrapping equipment lack coordination with the tape's winding state. Adjusting only a single piece of equipment can easily disrupt the wrapping tape's stability on the cable, thus affecting the consistency of wrapping quality.

[0004] Therefore, there is an urgent need for an optimized solution that adapts to the cable wrapping tape wrapping process to solve the related problems in the above-mentioned wrapping production process.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the general background of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

The real-time ambient temperature is obtained, and a secondary adjustment amount is obtained based on the real-time ambient temperature and the compensation amount. The wrapping parameters are then adjusted a second time based on the secondary adjustment amount.

[0008] Further, the wrapping parameters are initially adjusted, including: The initial adjustment amount of the wrapping speed is used as the initial adjustment amount, and the wrapping speed adjustment speed and the wrapping speed adjustment direction are obtained according to the wrapping speed and the initial adjustment amount of the wrapping speed.

The secondary adjustment amount of the wrapping speed is obtained by the relative deviation of the compensation tension and the preset adjustment step size; Based on the secondary adjustment amount and the preset adjustment ratio, the wrapping parameters are adjusted a second time in the same manner as the initial adjustment.

[0012] Furthermore, the compensation ratio will be retrieved, including: When the real-time ambient temperature is greater than the reference temperature, the temperature deviation trend is positive. When the real-time ambient temperature is lower than the reference temperature, the temperature deviation trend is negative. When the real-time ambient temperature is equal to the reference temperature, the compensation ratio is zero, or the temperature deviation trend is zero. The absolute value of the preset compensation ratio is retrieved based on the number of intervals, and the positive or negative relationship of the compensation ratio is obtained based on the temperature deviation trend.

[0018] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application. Attached Figure Description

[0019] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments recorded in the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0020] Figure 1 This is a flowchart illustrating a method for dynamic compensation of cable wrapping tape parameters. Figure 2 This is a schematic diagram of a dynamic compensation system for cable wrapping parameters. Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] 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. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] Example 1: like Figure 1 As shown, this application provides a method for dynamic compensation of cable wrapping tape parameters, the method including: Obtain the detection parameters of the wrapping tape, and based on the detection parameters, obtain the initial adjustment amount and target tension parameters of the wrapping parameters; the detection parameters include the initial wrapping angle and initial overlap rate of the wrapping tape, and the wrapping parameters include the wrapping speed of the wrapping machine and the height of the guide roller; The wrapping parameters are initially adjusted based on the initial adjustment amount to obtain the actual detection parameters, and the compensation amount is obtained based on the actual detection parameters. The real-time ambient temperature is obtained, and a secondary adjustment amount is obtained based on the real-time ambient temperature and the compensation amount. The wrapping parameters are then adjusted a second time based on the secondary adjustment amount.

[0024] Specifically, in one implementation, a high-precision vision sensor or laser goniometer is usually installed on the wrapping tape production line. When the wrapping tape is spirally wound on the cable core, the sensor captures the edge trajectory image of the wrapping tape in real time. Through image processing algorithms, the angle between the center line of the wrapping tape and the cable axis is identified. This angle is the wrapping angle. At the same time, the overlap rate of the wrapping tape is also identified. The wrapping speed refers to the rotational linear speed of the wrapping device in the wrapping machine that is responsible for pulling and winding the wrapped cable. This parameter is the core power parameter of the entire wrapping production line, which directly determines the production efficiency and the tension borne by the wrapping tape. When the wrapping speed increases, a pulling force is applied to the wrapping tape, increasing its tension; conversely, when the wrapping speed decreases, the tension of the wrapping tape will decrease accordingly. The guide wheel height refers to the vertical displacement of the guide wheel assembly on the wrapping machine, which is used to guide and position the wrapping tape, relative to the axis of the cable core wire. In operation, it is specifically manifested as the precise position of the guide wheel moving up and down in a plane perpendicular to the direction of the core wire's movement. Changes in the guide wheel height directly change the delivery path of the wrapping tape, thereby finely adjusting its winding geometry. In practice, the initial wrapping angle and initial overlap rate of the wrapping tape are first obtained through a visual inspection device or a measuring sensor. Based on the initial wrapping angle, initial overlap rate, and preset reference parameters, the initial adjustment amount of the wrapping parameters and the target tension parameters are calculated. Then, the wrapping speed and guide wheel height of the wrapping machine are adjusted synchronously according to the initial adjustment amount. After the initial adjustment, the actual wrapping angle and actual overlap rate of the wrapping tape are obtained again to calculate the compensation amount. Finally, the real-time ambient temperature of the current production environment is obtained. Based on the real-time ambient temperature and the compensation amount, the secondary adjustment amount is determined. Based on the secondary adjustment amount, the wrapping speed and guide wheel height are adjusted again to keep the wrapping state of the wrapping tape around the cable core wire stable.

[0025] The technical solution of this invention collects parameters such as wrapping angle, overlap rate and ambient temperature, calculates tension deviation and compensation amount, and adjusts wrapping speed and guide wheel height in a coordinated manner to achieve dynamic compensation and stable adjustment of cable wrapping state. This effectively solves the problem of insufficient wrapping quality consistency caused by the difficulty in dynamically and stably adjusting the wrapping state during the existing cable wrapping process.

[0026] Furthermore, the initial adjustments to the wrapping parameters include: The initial adjustment amount of the wrapping speed is used as the initial adjustment amount. The wrapping speed adjustment speed and the wrapping speed adjustment direction are obtained based on the wrapping speed and the initial adjustment amount of the wrapping speed. Based on the speed adjustment of the wrapping speed and the preset adjustment ratio, the guide wheel height adjustment speed and the guide wheel height adjustment direction are obtained. The guide wheel height adjustment direction is opposite to the wrapping speed adjustment direction. The wrapping speed and guide wheel height are adjusted synchronously based on the wrapping speed adjustment speed, wrapping speed adjustment direction, guide wheel height adjustment speed, and guide wheel height adjustment direction.

[0027] Furthermore, the compensation amount is obtained based on the actual detection parameters, including: The actual test parameters include the wrap angle and overlap rate after the initial adjustment; The changes in wrap angle and overlap rate after the initial adjustment are obtained based on the actual detection parameters. The ratio of the change in wrap angle to the initial wrap angle is taken as the wrap angle change ratio, and the ratio of the change in overlap rate to the initial overlap rate is taken as the overlap rate change ratio. The product of the wrap angle change ratio and the overlap rate change ratio is taken as the cooperative change ratio, and the compensation amount is obtained based on the target tension parameter and the cooperative change ratio.

[0028] Furthermore, obtaining the initial adjustment amount for the wrapping speed includes: Obtain the reference parameters for the wrapping tape, including the reference wrapping angle, reference overlap rate, and reference tension range; The relative deviation of the wrapping tape is obtained by comparing the reference parameters and the detection parameters; the relative deviation includes the relative deviation of the wrapping angle and the relative deviation of the overlap rate. The tension deviation coefficient is obtained based on the relative deviation and the preset deviation weight; When the tension deviation coefficient is greater than zero, the minimum value of the reference tension range is taken as the target tension parameter. When the tension deviation coefficient is less than zero, the maximum value of the reference tension range is taken as the target tension parameter. When the tension deviation coefficient is equal to zero, the reference tension value is retrieved as the target tension parameter; the midpoint of the reference tension range is the reference tension value. The product of the target tension parameter and the tension deviation coefficient is used as the real-time tension of the wrapping tape, and the relative tension deviation is obtained based on the reference tension value. The initial adjustment amount of the wrapping speed is obtained by comparing the relative deviation of the tension with the preset adjustment step size.

[0029] Furthermore, the wrapping parameters are adjusted a second time based on the secondary adjustment amount, including: The secondary adjustment amounts include the secondary adjustment amount for the wrapping speed and the secondary adjustment amount for the guide wheel height; Obtain the ambient temperature range, divide the ambient temperature range into continuous intervals, and obtain several ambient temperature sub-intervals; Set a temperature label and a reference temperature label for each ambient temperature sub-range; use the median value of the ambient temperature sub-range containing the reference temperature label as the reference temperature; The current temperature indicator is obtained based on the real-time ambient temperature. The number of intervals between the current temperature indicator and the reference temperature indicator is counted, and the temperature deviation trend is obtained. The compensation ratio is then calculated based on the number of intervals and the temperature deviation trend. The product of the compensation ratio and the compensation amount is used as the compensation tension, and the relative deviation of the compensation tension is obtained based on the compensation tension and the reference tension value. The secondary adjustment amount of the wrapping speed is obtained by compensating for the relative deviation of the tension and the preset adjustment step size; Based on the secondary adjustment amount and the preset adjustment ratio, the wrapping parameters are adjusted a second time in the same way as the initial adjustment.

[0030] Furthermore, the compensation ratio will be determined, including: When the real-time ambient temperature is greater than the reference temperature, the temperature deviation trend is positive. When the real-time ambient temperature is lower than the reference temperature, the temperature deviation trend is negative. When the real-time ambient temperature equals the reference temperature, the compensation ratio is zero, or the temperature deviation trend is zero. The absolute value of the preset compensation ratio is retrieved based on the number of intervals, and the positive or negative relationship of the compensation ratio is obtained based on the temperature deviation trend. The compensation ratio is obtained based on the positive / negative relationship and the absolute value of the compensation ratio.

[0031] As a preferred embodiment of the above embodiments, in one specific implementation, the initial adjustment amount of the wrapping speed is used as the initial adjustment amount; the process of obtaining the initial adjustment amount of the wrapping speed includes: Obtain the reference parameters for the wrapping tape, including the reference wrapping angle, reference overlap rate, and reference tension range; By observing and adjusting the wrapping tape's winding angle on the core wire, a stable angle value that ensures the wrapping layer is uniform, tight, and defect-free is found as the reference wrapping angle. The reference wrapping angle enables the wrapping tape to cover the core wire in the best way, avoiding gaps or uneven overlap, thereby ensuring the integrity and mechanical strength of the wrapping structure. The reference wrapping angle is usually a fixed value or a narrow angle range to adapt to the production needs of different product models. The covering effect of the wrapping tape during the winding process is analyzed to determine the optimal overlap ratio that achieves both sealing and protection as the baseline overlap rate. The baseline overlap rate ensures sufficient but not excessive overlap between adjacent wrapping tapes to prevent core wire exposure or material waste, while maintaining the flatness and consistency of the wrapping layer. The baseline overlap rate is generally expressed as a percentage and is allowed to fluctuate within a small range to accommodate normal variations in production. By assessing the material's behavior under tension, such as the risk of elongation, deformation, or breakage, a safe and effective tension range is established as the baseline tension range. This baseline tension range ensures the wrapping tape maintains appropriate tightness during winding; it is neither too loose, leading to loosening of the wrapping layer, nor too tight, causing material damage or performance degradation. The baseline tension range includes minimum and maximum tension values, providing clear upper and lower limits for production control. The relative deviation of the wrapping tape is obtained by comparing the reference parameters and the detection parameters; the relative deviation includes the relative deviation of the wrapping angle and the relative deviation of the overlap rate. ; in This represents the relative deviation around the wrap angle. Represents the initial wrap angle. Represents the reference wrap angle; ; in This represents the relative deviation of the overlap rate. Represents the initial overlap rate. Represents the baseline overlap rate; The tension deviation coefficient is obtained based on the relative deviation and the preset deviation weight: ; in Represents the tension deviation coefficient. and These represent the preset deviation weights; The deviation weights are determined based on the relative importance of the wrapping angle and overlap rate in the wrapping process to the final product quality. In practical applications, the weights are determined by analyzing historical production data. Specifically, if the deviation of the wrapping angle is more sensitive to the stability of the wrapping tape tension, the weight of the wrapping angle deviation will be set higher; conversely, if the deviation of the overlap rate has a more significant impact on product uniformity, the weight of the overlap rate deviation will be increased accordingly. The final specific values ​​of the weights need to be set according to product specifications and process requirements and kept stable during production to ensure the consistency of the control strategy. When the tension deviation coefficient is greater than zero, the minimum value of the reference tension range is used as the target tension parameter; when the tension deviation coefficient is less than zero, the maximum value of the reference tension range is used as the target tension parameter; the median value of the reference tension range is the reference tension value. When the tension deviation coefficient is equal to zero, the reference tension value is retrieved as the target tension parameter. A tension deviation coefficient greater than zero indicates that the current initial wrapping angle or initial overlap rate, or both, is larger than the reference value. In the wrapping process, this usually means that the wrapping tape is in a state of being too tight or over-wound. For example, a larger wrapping angle means tighter winding, and a larger overlap rate means more overlapping. In order to actively counteract this tendency to be too tight and prevent the tension from increasing further during the wrapping process, which could lead to material stretching or damage, the control system needs to preset a relatively loose tension environment. Therefore, the minimum allowable tension value within the reference tension range is selected as the target. Conversely, a tension deviation coefficient less than zero indicates that the current wrapping condition is too small, suggesting a tendency to be too loose. At this time, the wrapping is not tight and there is a risk of loosening. In order to actively prevent loosening that leads to poor wrapping, wrinkling, or performance degradation, a tighter tension environment needs to be preset. Therefore, the maximum allowable tension value within the reference tension range is selected as the target. A tension deviation coefficient of zero indicates that the current detection parameters perfectly match the reference parameters, and the system is in an ideal state of equilibrium. At this time, there is no obvious deviation trend of being too tight or too loose that needs to be corrected. Therefore, the most robust and balanced choice is to use the reference tension value. The reference tension value represents the optimal set point of the tension, which can provide sufficient buffer space for fluctuations while ensuring quality, so that the system operates in the center of the optimal range and remains stable. The product of the target tension parameter and the tension deviation coefficient is used as the real-time tension of the wrapping tape. ; in Represents real-time tension. Represents the target tension parameter. Represents the tension deviation coefficient; Real-time tension transforms the tension deviation coefficient, which reflects the deviation of the initial wrapping angle and initial overlap rate of the wrapping tape, into a specific tension control target; by multiplying the tension deviation coefficient by the target tension parameter, the control direction required to correct the deviation is amplified and locked. And the relative tension deviation is obtained based on the reference tension value: ; in This represents the relative deviation of tension. This represents the reference tension value; when the reference tension value is equal to the real-time tension, the relative tension deviation is equal to the tension deviation coefficient. When K is greater than zero, meaning the wrapping tape is in a slightly tight state, the minimum value of the reference tension range is selected as the loose target. Furthermore, through the amplification effect of 1+K, the tension increase command is further strengthened, aiming to more proactively and forcefully suppress the trend of continuously increasing tightness. Conversely, when K is less than zero, meaning the wrapping tape is in a slightly loose state, the system selects the maximum value of the reference tension range as the tension target while utilizing the reduction effect of 1+K to make the tension setting more gentle and cautious, avoiding unexpected risks caused by excessive tightening on a loose basis. The initial adjustment amount of the wrapping speed is obtained by adjusting the relative tension deviation and the adjustment step size: ; in This represents the initial adjustment amount for the wrapping speed. This represents adjusting the step size; The adjustment step size needs to be balanced between response speed and stability. Its value should be pre-calibrated and determined based on the dynamic response characteristics of the equipment and the process quality requirements. If the step size is too large, it will cause oscillation and overshoot in the adjustment process, which will destroy the stability of production. If the step size is too small, it will make the correction process slow and unable to offset the deviation in time, resulting in a delayed response. Therefore, setting an appropriate adjustment step size can ensure that the system can react quickly enough after detecting the deviation, and converge to the target state smoothly and without shock. The wrapping parameters are initially adjusted based on the initial adjustment amount to obtain the actual detection parameters, and the compensation amount is obtained based on the actual detection parameters. The initial adjustment process includes: The initial adjustment amount of the wrapping speed is used as the initial adjustment amount; based on the wrapping speed and the initial adjustment amount, the adjustment speed and direction of the wrapping speed are obtained: ; in This represents the speed adjustment for wrapping the package. This represents the preset adjustment time. This represents the initial adjustment amount of the wrapping speed; increasing the wrapping speed is taken as the positive direction of the wrapping speed adjustment, and decreasing the wrapping speed is taken as the negative direction of the wrapping speed adjustment; when the initial adjustment amount of the wrapping speed is greater than zero, the wrapping speed adjustment direction is positive, and vice versa. The guide wheel height adjustment speed and the guide wheel height adjustment direction are obtained by adjusting the speed according to the wrapping speed and the preset adjustment ratio; raising the guide wheel is taken as the positive direction of the guide wheel height adjustment, and lowering the guide wheel is taken as the negative direction of the guide wheel height adjustment. The direction of guide wheel height adjustment is opposite to the direction of wrapping speed adjustment; When it is necessary to increase the tension of the wrapping tape, the wrapping speed will be increased. However, if the height of the guide roller remains unchanged, the increase in wrapping speed will tend to reduce the wrapping angle, resulting in a tighter wrapping. To counteract this side effect and maintain the ideal wrapping angle, the height of the guide roller must be reduced to compensate. Conversely, when it is necessary to reduce the tension and reduce the wrapping speed, the height of the guide roller must be increased at the same time to prevent the wrapping angle from becoming too large. Therefore, the direction of adjustment of the guide roller height is always opposite to the direction of adjustment of the wrapping speed in order to maintain the stability of the wrapping geometry. The wrapping speed and guide wheel height are adjusted synchronously according to the wrapping speed adjustment speed, the wrapping speed adjustment direction, the guide wheel height adjustment speed, and the guide wheel height adjustment direction; The process of obtaining the compensation amount includes: The actual test parameters include the wrap angle and the overlap rate after the initial adjustment; The changes in wrap angle and overlap rate after the initial adjustment are obtained based on the actual detection parameters; the changes in wrap angle and overlap rate are non-negative; the ratio of the change in wrap angle to the initial wrap angle is taken as the wrap angle change ratio, and the ratio of the change in overlap rate to the initial overlap rate is taken as the overlap rate change ratio. The change ratio is calculated to eliminate the influence of the dimensions and absolute size of the initial values, and normalizes the degree of change of the wrap angle and overlap rate before and after the adjustment into a dimensionless relative proportion. The product of the wrap angle change ratio and the overlap rate change ratio is taken as the cooperative change ratio. The compensation amount is obtained based on the target tension parameter and the cooperative change ratio. ; in Represents the amount of compensation. Represents the target tension parameter. Represents the ratio of coordinated changes; As the product of the wrap angle and the overlap ratio, the synergistic change ratio comprehensively evaluates the synergistic effect of the initial adjustment; its value reflects the coupling effect of the changes in the two parameters: the closer the value is to 1, the more the adjustment effect meets expectations; a value deviating from 1 indicates insufficient or excessive effect. When the co-change ratio is 1, the deviation is zero and the compensation amount is zero, indicating that no adjustment compensation is needed; when the co-change ratio is less than 1, the deviation is positive and the compensation amount is positive, and additional compensation is added to correct insufficient adjustment; when the co-change ratio is greater than 1, the deviation is negative and the compensation amount is negative, and reverse compensation is performed to correct over-adjustment. The real-time ambient temperature is obtained, and the secondary adjustment amount is obtained based on the real-time ambient temperature and the compensation amount. The wrapping parameters are then adjusted again based on the secondary adjustment amount. The process of making secondary adjustments includes: The ambient temperature range is obtained, and the range is divided into continuous intervals to obtain several sub-intervals. Small, negligible temperature fluctuations are filtered out. Only when the temperature change is large enough to cross a sub-interval is it considered to have generated an effective temperature change that needs to be compensated. Set a temperature identifier and a reference temperature identifier for each ambient temperature sub-range; use the median value of the ambient temperature sub-range where the reference temperature identifier is located as the reference temperature; the temperature identifier maps continuous physical quantities to discrete logical states, which facilitates accurate logical judgment. The current temperature is obtained based on the real-time ambient temperature. The number of intervals between the current temperature and the reference temperature is counted, and the temperature deviation trend is obtained. The compensation ratio is calculated based on the number of intervals and the temperature deviation trend. The number of intervals quantitatively describes the degree of deviation of the current temperature from the reference temperature. The more intervals, the greater the deviation. The process of retrieving the compensation ratio includes: When the real-time ambient temperature is greater than the reference temperature, the temperature deviation trend is positive. When the real-time ambient temperature is lower than the reference temperature, the temperature deviation trend is negative. When the real-time ambient temperature equals the reference temperature, the compensation ratio is zero, or the temperature deviation trend is zero. The absolute value of the preset compensation ratio is retrieved according to the number of intervals, and the positive or negative relationship of the compensation ratio is obtained according to the temperature deviation trend; the compensation ratio is obtained based on the positive or negative relationship and the absolute value of the compensation ratio. The product of the compensation ratio and the compensation amount is used as the compensation tension, and the relative deviation of the compensation tension is obtained. A linear relationship between the compensation amount and the intensity and direction of temperature disturbance is realized. A positive trend, that is, higher temperature usually means material expansion and relaxation, which requires a positive compensation ratio, such as increasing the tension, to counteract it. A negative trend requires a negative compensation ratio, such as decreasing the tension. The secondary adjustment amount of the wrapping speed is obtained by compensating for the relative deviation of the tension and adjusting the step size; The secondary adjustment includes the secondary adjustment of the wrapping speed and the secondary adjustment of the guide wheel height; according to the secondary adjustment and the preset adjustment ratio, the wrapping parameters are adjusted a second time in the same way as the initial adjustment. For example, in one specific embodiment: Preset reference parameters: Reference wrapping angle 45°, as this angle allows the wrapping tape to evenly cover the core wire, avoiding gaps and uneven overlap; reference overlap rate 20%, balancing sealing performance and material saving, conforming to the optimal ratio of conventional processes; reference tension range 50N-70N, with an intermediate value of 60N (reference tension value), adapting to the tensile strength of common wrapping tape materials, preventing damage from being too loose or too tight; weighting of relative deviation of wrapping angle. =0.6, Weight of relative deviation of overlap rate =0.4, historical production data shows that the wrap angle is more sensitive to tension stability, therefore it is given a higher weight; adjust the step size. =0.5m / min, balancing response speed and stability, adapting to the dynamic characteristics of most wrapping machines; preset adjustment time of 2s, matching the mechanical response speed of the wrapping machine, ensuring smooth adjustment without impact; Preset environmental parameters: Ambient temperature range of 15℃-35℃, covering mainstream production environments; divided into 5 temperature sub-ranges: 15-19℃ (label 1), 19-23℃ (label 2), 23-27℃ (label 3), 27-31℃ (label 4), and 31-35℃ (label 5), filtering out minor temperature fluctuations; the reference temperature label is set to 3, with a reference temperature of 25℃, which is the suitable ambient temperature for the wrapping process; preset compensation ratio: absolute value of 0.1 when the interval is 1 unit and absolute value of 0.2 when the interval is 2 units. The greater the temperature deviation, the greater the impact on tension, and the compensation ratio must be linearly matched.
