Description

[0002] After manufacturing, aviation communication cables need to be wound onto spools for easy transport. To ensure the safety of these cables during transport, the regularity and tightness of the winding on the spools must meet certain requirements. Existing technologies adjust the rotation angle of pulley assemblies to allow the communication cable to be wound tightly onto the spool at a corresponding angle. However, existing pulley assemblies are typically set to a fixed angle. If set to a fixed angle, the cable may experience excessive tension at certain winding angles, potentially breaking or deforming the cable and causing damage. Alternatively, operators can manually adjust the rotation angle of the pulley assembly based on experience to match the winding angle of the communication cable. However, this method is labor-intensive, and operators cannot precisely and in real-time adjust the rotation angle, affecting the quality of the winding on the spools. Therefore, existing technologies suffer from the inability to efficiently adjust the winding angle of the communication cable. Summary of the Invention

[0034] Please see Figure 1 and Figure 2 , Figure 1 This is a flowchart illustrating the automatic adjustment method for the take-up pulley of an aviation communication cable provided in an embodiment of the present invention. Figure 2 This is a schematic diagram illustrating an application scenario of the automatic adjustment method for the take-up pulley of an aviation communication cable provided in an embodiment of the present invention. The automatic adjustment method for the take-up pulley of the aviation communication cable is applied in a control terminal 10. The control terminal 10 is communicatively connected to an image acquisition device 20 and a rotary drive device 30 to transmit data information. The drive shaft of the rotary drive device 30 is fixedly connected to the pulley assembly 40. Figure 3 and Figure 4 As shown, the pulley assembly 40 includes two parallel take-up pulleys 41. The aviation communication cable 1 passes between the parallel take-up pulleys 41 and is wound around the surface of the reel 2. The pulley assembly 40 is rotatably mounted on the bracket 3. The rotation drive device 30 is fixedly mounted on one side of the bracket, and the image acquisition device 20 is fixedly mounted on the side of the bracket facing the reel 2. The specific positions of the rotation drive device 30 and the image acquisition device 20 are as follows: Figure 5 As shown; the drive shaft of the rotary drive device 30 passes through the bracket 3 and is fixedly connected to the pulley assembly 40. The rotary drive device 30 drives the pulley assembly 40 to rotate relative to the bracket 3 via the drive shaft. The aviation communication cable 1 is composed of at least two even-numbered strands twisted together. The automatic adjustment method for the take-up pulley of this aviation communication cable is executed by application software installed in the control terminal 10. The control terminal 10 is the terminal device used to execute the automatic adjustment method for the take-up pulley of the aviation communication cable to automatically adjust the rotation angle of the pulley assembly 40. The control terminal 10 can be a desktop computer, laptop computer, tablet computer, or server terminal, or an MCU control chip, FPGA logic circuit, etc., integrated on one side of the rotary drive device 30. Figure 1 As shown, the method includes steps S110 to S150.

[0035] S110. Upon receiving the start command, the cable image acquired by the image acquisition device is obtained.

[0036] The control terminal can receive start commands input by the user, which include information such as the operator's identification (ID), command generation time, and cable type. After receiving the start command, the control terminal acquires the cable image captured by the image acquisition device. Since the image acquisition device is positioned facing the cable reel, it can capture the image of the communication cable extending from the pulley assembly to the cable reel. To increase the viewing angle for image acquisition, the image acquisition device can be a wide-angle camera.

[0037] S120. The cable image is parsed according to a preset parsing strategy to obtain the corresponding cable take-up position information.

[0038] Furthermore, the cable image can be analyzed according to the analysis strategy, thereby converting the cable image containing image information into cable reel position information represented by numerical features. The cable reel position information includes the target reel position and the reel direction. The target reel position is the specific position where the communication cable is currently in contact with the reel; for aviation communication cables, this means the cable is in contact with the reel and begins to wind around the reel at the contact point. The reel direction is the specific direction in which the aviation communication cable extends towards the reel.

[0039] In one embodiment, step S120 specifically includes the following sub-steps: dissolving pixels in the cable image according to the image dissolving parameters in the parsing strategy to obtain a corresponding image contour; filtering the image contour according to the contour filtering rules in the parsing strategy to obtain a corresponding target contour; obtaining the intersection point of the target contour and the preset contact surface in the parsing strategy as the cable take-up target position; obtaining the contour azimuth angle corresponding to the target contour as the cable take-up azimuth; and combining the cable take-up target position and the cable take-up azimuth to obtain the corresponding cable take-up position information.

[0040] Specifically, the image can be pixel-dissolved according to the image dissolving parameters in the analysis strategy. This allows for the calculation of the pixel difference coefficient between each pixel and its surrounding pixels. For example, the difference between a given pixel and its eight surrounding pixels in the red (R), green (G), and blue (B) channels is calculated, and the average of these eight differences is taken as the pixel difference coefficient. The pixel difference coefficient reflects the pixel difference between a given pixel and its surrounding pixels; the greater the pixel difference, the larger the pixel difference coefficient.

[0041] The cable image is pixel-dissolved based on the image dissolution parameter and the pixel difference coefficient of each pixel. This means removing pixels with smaller pixel difference coefficients and retaining only those with larger coefficients. For example, if the pixels in the cable image are sorted according to their pixel difference coefficients, with larger coefficients appearing first, and the image dissolution parameter is 0.2, then the top 20% of the sorted pixels are retained, and the remaining pixels are dissolved and removed. The retained pixels are then binarized (set to "1" for retained pixels and "0" for dissolved pixels) to obtain the corresponding image outline.

[0042] The image contours are further filtered according to the contour filtering rules in the analysis strategy to obtain the target contour corresponding to the aviation communication cable. The target contour includes two adjacent straight lines. The centerline corresponding to the two straight lines can be determined based on the target contour. The intersection of this centerline and the preset contact surface in the analysis strategy is obtained as the cable take-up target position. The cable take-up target position includes the three-dimensional coordinate value of the intersection point. The preset contact surface is the contact surface corresponding to the surface of the cable reel, which is a vertical section passing through the axis of the cable reel. During the cable take-up process of the aviation communication cable, the intersection point in the cable take-up target position moves from the left side to the right side of the cable reel. After completing the winding of one layer of cable, it moves from the right side of the cable reel to the left side to complete the winding of a new layer of cable, and so on.

[0043] Furthermore, based on the centerline of the two straight lines in the target contour, the angle between this centerline and the horizontal axis is determined as the corresponding contour azimuth angle, which is also the cable take-up direction. The horizontal axis is the horizontal line connecting the center point of the pulley assembly and the center point of the cable reel. Combining the target take-up position with the take-up direction yields the cable take-up position information corresponding to the cable image.

[0044] In one embodiment, the step of filtering the image contours according to the contour filtering rules in the parsing strategy to obtain the corresponding target contours includes: filtering out contour lines in the image contours whose consecutive pixel count is less than the number threshold according to the number threshold in the contour filtering rules; calculating the angle between each contour line in the image contour and a preset baseline to obtain the corresponding contour angle; filtering the contour angles of each contour line according to the angle interval in the contour filtering rules to obtain contour lines that match the angle interval as candidate contour lines; obtaining the angle difference between adjacent contour lines in the candidate contour lines; and obtaining the two adjacent contour lines with the smallest angle difference in the candidate contour lines as the corresponding target contours.

[0045] An image contour contains multiple contour lines. The steps for filtering the contour lines in an image contour are as follows: First, determine the number of consecutive pixels for each contour line in the image contour. The number of consecutive pixels is the total number of pixels contained in an uninterrupted combination of pixels in a single contour line. Then, filter out contour lines whose number of consecutive pixels is less than a threshold in the contour filtering rules. For example, if the threshold is set to "10", contour lines with fewer than 10 consecutive pixels are filtered out, and only contour lines with more than 10 consecutive pixels are retained. Next, calculate the angle between each contour line and a preset baseline as the contour angle. Each contour line can then have a corresponding contour angle calculated. This baseline can be the horizontal line connecting the center point of the pulley assembly and the center point of the coil.

[0046] Further filtering is performed on the included angles of each contour line according to the included angle range in the contour filtering rules, thereby obtaining contour lines whose included angles fall within the included angle range as candidate contour lines. For example, the included angle range can be set to [22°, -22°]. The angle difference between adjacent contour lines in the candidate contour lines is then obtained. Since the outer contours on both sides of the aviation communication cable are almost parallel, the angle difference between adjacent contour lines in the candidate contour lines can be calculated, and the corresponding target contour can be obtained based on this angle difference. Specifically, the two adjacent contour lines with the smallest angle difference among the candidate contour lines can be obtained as the target contour, and the two straight lines in the target contour are nearly parallel.

[0047] S130. Set the take-up angle value corresponding to the start command and the cable take-up position information according to the preset angle setting rules.

[0048] The take-up angle value can be set according to the angle setting rules, corresponding to the start command and cable take-up position information. This take-up angle value is used to control the rotation angle of the pulley assembly.

[0049] In one embodiment, step S130 includes the following steps: obtaining basic cable information corresponding to the cable type in the start command; performing angle analysis on the basic cable information and the take-up orientation in the cable take-up position information according to the angle analysis function in the angle setting rule to obtain the corresponding basic angle value; adjusting the tension of the take-up target position and take-up orientation in the cable take-up position information according to the tension adjustment function in the angle setting rule to obtain the corresponding adjustment coefficient; adjusting the basic angle value with the adjustment coefficient to obtain the corresponding take-up angle value.

[0050] Specifically, the basic cable information corresponding to the cable type in the startup command can be obtained. The basic cable information includes basic parameters related to aviation communication cables, such as communication frequency, cable outer diameter, and number of cable strands.

[0051] The cable foundation information and cable take-up orientation are analyzed using the angle analysis function to obtain the corresponding foundation angle value. The angle analysis function can be expressed by formula (1):

[0052] (1);

[0053] Where r0 is the radius of the take-up pulley in the pulley assembly (the radii of the two take-up pulleys in the pulley assembly are equal), d is the outer diameter of the cable in the cable basic information, L0 is the distance between the centers of the two take-up pulleys in the pulley assembly; β is the angle between the line connecting the centers of the two take-up pulleys in the pulley assembly and the centerline corresponding to the two straight lines in the target contour; α is the angle value in the take-up orientation. If the aviation communication cable extends to the left of the cable reel, α is a positive value; if the aviation communication cable extends to the right of the cable reel, α is a negative value; π / 2 is the radian value, corresponding to an angle of 90°. M is the basic angle value obtained from the analysis. When M is 0°, the line connecting the centers of the two take-up pulleys is perpendicular to the baseline, that is, the pulley assembly is in the initial position; when M is not 0°, the line connecting the centers of the two take-up pulleys rotates counterclockwise by the angle value M from the initial position. The specific geometric relationship of the angle value is as follows: Figure 6 As shown.

[0054] Furthermore, in order to straighten the communication cable during winding on the reel, a certain tension needs to be provided between the pulley assembly and the reel. This tension must be appropriate. If the tension is too high, the communication cable may break and be damaged. If the tension is too low, the communication cable will sag due to gravity between the pulley assembly and the reel, affecting the tightness of the winding of the communication cable on the reel. The tension can be adjusted by the tension adjustment function in the angle setting rules to adjust the target position and orientation of the winding, thereby obtaining the corresponding adjustment coefficient. Specifically, the tension adjustment function can be expressed by formula (2):

[0055] (2);

[0056] S t The adjustment coefficient is calculated as follows: h is the vertical height calculated based on the coordinates of the intersection point in the target position of the cable take-up (the vertical height of the intersection point of the communication cable and the preset contact surface from the surface of the cable reel); r is the radius of the central cylinder of the cable reel (the cable reel consists of a central cylinder and circular baffles at both ends); α is the angle value in the take-up orientation; π is pi; and "||" is the absolute value operator.

[0057] Further adjustments are made to the base angle value based on the adjustment coefficients obtained from the analysis, thereby obtaining the corresponding take-off angle value. The process of adjusting the base angle value can be expressed as (1+S) t If the result is )×M, then the final take-up angle value is the value corresponding to the start command and cable take-up position information.

[0058] S140. Set the deflection speed corresponding to the cable take-up position information according to the preset deflection setting rules.

[0059] Furthermore, a deflection speed corresponding to the cable winding position information is set according to the deflection setting rules. This deflection speed is used to control the rotation speed of the pulley assembly over a future period of time. As the number of layers of aviation communication cable on the reel increases during cable winding, the time required to wind one turn of cable on the reel increases when the cable conveying speed remains constant. Therefore, it is necessary to control the rotation speed of the pulley assembly to match the cable winding speed.

[0060] In one embodiment, step S140 includes the following steps: calculating the deflection coefficient corresponding to the cable take-up target position in the cable take-up position information according to the deflection function in the deflection setting rule; multiplying the deflection coefficient by the base speed in the deflection setting rule to obtain the corresponding deflection speed.

[0061] Specifically, the deflection coefficient corresponding to the target position can be calculated based on the deflection function in the deflection setting rules. The process of obtaining the deflection coefficient can be expressed as r / (h+r), and the result is the deflection coefficient. Here, r is the radius of the central cylinder of the spool, h is the vertical height calculated based on the coordinates of the intersection point in the target position, and the obtained deflection coefficient is a value no greater than 1.

[0062] Multiply the deflection coefficient by the base speed in the deflection setting rules, and add the corresponding sign to the result value according to the direction of movement of the intersection point at the target position to obtain the deflection speed; for example, if the direction of movement of the intersection point at the target position is "from left to right", the sign is "+"; if the direction of movement is "from right to left", the sign is "-". If the base speed is 2° / min, the base speed means that the pulley assembly needs to rotate 2° per minute, and the obtained deflection speed is not greater than this base speed.

[0063] S150. Send the corresponding rotation control command to the rotation drive device according to the take-up angle value and the deflection speed.

[0064] Based on the take-up angle and deflection speed, a corresponding rotation control command is sent to the rotation drive device, thereby controlling the rotation drive device to adjust the angle of the pulley assembly according to the rotation control command.

[0065] In one embodiment, step S150 includes the following steps: configuring the initial command with parameters according to the take-up angle value and the deflection speed to generate a corresponding rotation control command; sending the rotation control command to the rotation drive device to control the rotation drive device to adjust the angle of the pulley assembly according to the rotation control command.

[0066] Specifically, the initial command can be configured with parameters based on the take-up angle and deflection speed. The initial command includes multiple parameters, with the three parameters corresponding to the take-up angle and deflection speed being empty. The values ​​of the take-up angle and deflection speed can be obtained and the corresponding parameter values ​​in the initial command configured. The parameter value corresponding to the rotation direction is configured according to the sign of the deflection speed: a positive sign indicates clockwise rotation, and a negative sign indicates counter-clockwise rotation. After parameter configuration, the corresponding rotation control command is generated. This generated rotation control command is sent to the rotation drive device, which then controls the pulley assembly to adjust its angle according to the command. The rotation drive device controls the pulley assembly to rotate to the corresponding angle based on the take-up angle parameter in the rotation control command, and then controls the pulley assembly to rotate clockwise or counter-clockwise at the corresponding speed based on the deflection speed parameter in the rotation control command.

[0067] In one embodiment, after step S150, the method further includes the following steps: determining whether the interval time corresponding to the rotation control command exceeds a preset time threshold; the interval time is the time interval between the sending time of the rotation control command and the current time; if the interval time exceeds the time threshold, then returning to the step of obtaining the cable image acquired by the image acquisition device.

[0068] Furthermore, it can be determined whether the interval time corresponding to the rotation control command exceeds a preset time threshold. This interval time is the time interval between the sending time of the rotation control command and the current time; for example, the time threshold can be set to 1 second. If the interval time exceeds the time threshold, then return to step S110, that is, to acquire the cable image again and parse it to generate a new rotation control command; if the interval time does not exceed the time threshold, then return to the step of determining whether the interval time corresponding to the rotation control command exceeds the preset time threshold.

[0069] In the automatic adjustment method for take-up pulleys of aviation communication cables provided in this embodiment of the invention, the method includes: receiving a start command, then acquiring a cable image acquired by the image acquisition device; parsing the cable image according to a preset parsing strategy to obtain corresponding cable take-up position information; setting a take-up angle value corresponding to the start command and the cable take-up position information according to a preset angle setting rule; setting a deflection speed corresponding to the cable take-up position information according to a preset deflection setting rule; and sending a corresponding rotation control command to the rotation drive device according to the take-up angle value and the deflection speed. Through the above method, the rotation angle of the pulley assembly can be accurately and in real-time adjusted based on the position information of the communication cable, significantly improving the reliability of take-up aviation communication cables.
