Description

Technical Field

[0001] This utility model belongs to the field of servo motor zeroing, and in particular relates to a system for quickly detecting whether the plane on which the servo surface is located overlaps with the marking line and then making adjustments. Background Technology

[0002] Neutral adjustment is a crucial step in the calibration of remote-controlled models such as airplanes and boats. Its purpose is to ensure that when the servo motor is in the neutral position, the control surfaces (such as ailerons and rudder) maintain their initial, unbiased state. Inaccurate neutral adjustment can lead to problems such as yaw and pitch abnormalities during model flight / navigation.

[0003] Mechanical zeroing involves adjusting the physical positions of the servo arm and linkage to ensure the control surface is in a neutral state. First, install the servo arm vertically on the servo output shaft (90° position), ensuring that the arm is perpendicular to the servo axis when the servo is powered on and in the neutral position. Next, adjust the length of the push rod connecting the servo and the control surface to maintain no deflection of the control surface in its natural state. Simultaneously, check that the angle between the linkage, the servo arm, and the control surface rocker arm is close to 90° to reduce mechanical wear and play. If the control surface still deviates, manually adjust the linkage length or reinstall the servo arm to ensure the mechanical structure is symmetrical and secure.

[0004] Electronic zeroing utilizes the fine-tuning function of the remote control to correct the neutral position of the control surface. First, ensure all fine-tuning on the remote control is zeroed and set the servo channel travel to its default value. After powering on, observe if the control surface is centered. If there is a deviation, use the remote control to fine-tune the servo's neutral point until the control surface is completely centered. Additionally, check the symmetry of the control inputs: fully deflect the left or right, or up or down. If the deflection angle is inconsistent, adjust the control input limits or further optimize to ensure symmetrical and precise control surface movement. Electronic zeroing is suitable for correcting minor deviations; if the offset is too large, mechanical zeroing must be used in conjunction.

[0005] The traditional method of zeroing involves visually observing whether the four servo motor surfaces align with the markings to determine if the surfaces are at zero. If not, the angles are manually estimated and adjusted, and the servo motors are rotated to bring the surfaces to zero. This method suffers from problems such as large zeroing errors and long zeroing times.

[0006] Therefore, the existing technology has the following problems: (1) visual errors caused by the observation angle deviating from the vertical direction; (2) when repeatedly switching the observation target, the human eye needs to refocus, which may cause misreading due to fatigue and focus interference; (3) long-term observation can easily lead to eye muscle fatigue, which reduces the accuracy of continuous judgment and causes physiological fatigue; (4) the brain tends to "see the expected value" and ignores the actual deviation, which causes psychological misguidance; (5) the problem of large workload caused by workers needing to observe from four directions around the workbench. Summary of the Invention

[0007] The purpose of this invention is to provide a system for quickly detecting whether the plane on which the control surface is located overlaps with the marking line and then making adjustments accordingly. This solves the problem of large zeroing errors and long zeroing times caused by the human eye having to observe whether the control surfaces of the four servo motors overlap with the marking line to determine whether the control surface is at zero.

[0008] This utility model adopts the following technical solution: a system for quickly detecting and adjusting whether the plane where the control surface is located overlaps with the marking line, comprising: A photographic device used to capture images of the area where the servo motor's control surface and the markings are located. The acquisition module is used to acquire and send the detection images captured by the camera. The processing module contains a standard image of the plane where the control surface is located and the datum line are superimposed. The recognition module is used to receive the detection image and the standard image, and to identify the angle between the rudder markings in the standard image and the rudder markings in the detection image; it is also used to identify the angle between the plane containing the rudder surface in the standard image and the plane containing the rudder surface in the detection image. The judgment module determines that the rudder surface and the rudder surface coincide when the absolute value of the difference between the angle between the rudder marking and the angle between the rudder surface and the rudder surface is less than or equal to a predetermined value.

[0009] The beneficial effects of this utility model are: The present invention completes the zeroing of 4 control surfaces in less than 2 minutes, while the prior art requires about 30 repeated control surface adjustments and takes about 15 minutes to complete the zeroing of 4 control surfaces. According to the results of the re-inspection, this utility model may only have one case of adjustment exceeding the tolerance or being unable to be adjusted once every 50 rudder surfaces are adjusted; while in the prior art, the zero point position of one rudder surface will exceed the tolerance once every 10 rudder surfaces are adjusted. The photographing device of this utility model can take pictures of the area where the servo surface and the marking line are located through four photographing devices. Then, by analyzing the photographs, it can be determined whether the servo surface and the marking line overlap, and adjustments can be made to make the servo surface and the marking line overlap. The photographing device of this utility model has a fixing block that locks the mounting sleeve, thereby allowing the height of the mounting sleeve to be adjusted, and the height of the photographing device to be adjusted as well, so that it can be aimed at the area where the rudder surface and the marking line are located for taking pictures.

[0016] The judgment module 31 is also used to: when the absolute value of the difference between the rudder surface angle and the control surface angle is greater than a predetermined value, determine that the control surface and the rudder surface do not coincide, and send an adjustment signal and an adjustment value.

[0017] This utility model also includes: an adjustment module 32, which is used to receive adjustment signals and send adjustment values ​​to the control system of the servo motor, thereby causing the control system of the servo motor to adjust the angle of the control surface until the absolute value of the difference between the reticle angle and the control surface angle is less than or equal to a predetermined value.

[0018] Preferably, the predetermined value is 0.1 degrees.

[0019] The photographic device of this utility model, such as Figure 1 and Figure 2 As shown, it includes: a support base plate 10, four shooting support plates 11, four mounting sleeves 14, and four shooting devices 15.

[0020] The support base plate 10 is horizontally set and fixed on the horizontal platform surface; a servo motor 20 is vertically placed at the center of the support base plate 10.

[0021] Four shooting support plates 11 are horizontally arranged and evenly spaced around the support base plate 10. The bottom of the four shooting support plates 11 is fixed on the horizontal platform. Each shooting support plate 11 includes an integrally connected enlarged support plate 12 and a slender connecting plate 13. The inner end of each slender connecting plate 13 is integrally connected to the support base plate 10, and the outer end of each slender connecting plate 13 is integrally connected to the corresponding enlarged support plate 12. Each enlarged support plate 12 is provided with a mounting hole 21.

[0022] Four mounting sleeves 14 are respectively fitted into the corresponding mounting holes 21.

[0023] Four photographing devices 15 are fixed to the upper end of their respective mounting sleeves 14, thereby enabling the photographing devices 15 to take pictures of the positions of the four control surfaces of the servo motor 20 corresponding to the marking lines.

[0024] like Figure 3As shown, the expanded support plate 12 has fixing holes 22 on both sides of the mounting hole 21; a fixing block 16 is also provided on the upper side of the expanded support plate 12. A through hole 17 is provided in the center of the fixing block 16 for the mounting sleeve 14 to pass through. Insertion holes 18 are provided on both sides of the fixing block 16 at positions corresponding to the fixing holes 22. The insertion holes 18 are used for the first fixing member to be inserted. The first fixing member is used to first pass through the insertion hole 18 and then extend into the fixing hole 22, thereby fixing the mounting sleeve 14 through the fixing block 16, and thus adjusting the height of the mounting sleeve 14 in order to adjust the height of the photographing device 15.

[0025] The fixing block 16 is "C" shaped, with its two ends close to each other and horizontal holes 19. The two horizontal holes 19 are arranged correspondingly to each other, so that the second fixing member can be inserted and the mounting sleeve 14 can be fixed.

[0026] The mounting sleeve 14 is fixed to the expanded support plate 12 by the first fixing member, and then the mounting sleeve 14 is clamped and fixed by the second fixing member to prevent the mounting sleeve 14 from sliding left and right. Therefore, the first fixing member is to prevent the mounting sleeve 14 from moving vertically, and the second fixing member is to prevent the mounting sleeve 14 from swinging horizontally.

[0027] like Figure 4 As shown, a limiting ring 23 is fixedly connected at the center of the support base plate 10, where the servo motor 20 is placed. The limiting ring 23 is annular and horizontally arranged. The limiting ring 23 is used to place the servo motor 20. An opening 27 is provided on one side of the limiting ring 23 for the wire of the servo motor 20 to extend out. A retaining plate 24 is provided at the edge of the support base plate 10. The retaining plate 24 is used to fix the wire of the servo motor 20 to avoid affecting the upright state of the servo motor 20.

[0028] like Figure 5 As shown, a servo hole 25 is provided through the center of the support base plate 10 from top to bottom. Multiple locking blocks 26 are fixedly connected around the servo hole 25 on the support base plate 10. Each locking block 26 is used to extend into the servo 20 and thus lock the servo 20.

[0029] Preferably, the four shooting support plates 11 are respectively set to correspond to the four control surfaces of the servo motor 20.

[0030] The marking line of this utility model is a line marked on the servo housing during the production process of the servo 20. The marking line is set close to the control surface and coincides with the plane where the control surface is located after zeroing. Therefore, the four marking lines are evenly parallel to the axis of the servo housing.

[0031] The method of using this photographic device is as follows: Place the servo motor 20 inside the limiting ring 23, ensuring that the lower center of the servo motor 20 passes through the servo motor hole 25, and that each locking block 26 locks the lower end of the servo motor 20, thereby ensuring the vertical state of the servo motor 20. Then, lead the wire of the servo motor 20 out from the opening 27, and use the locking plate 24 to lock the wire at the edge of the support base plate 10. Then, by loosening the second fixing member and the first fixing member, make the photographing device 15 face the area where the servo surface and the marking line are located. Then, tighten the first fixing member and the second fixing member to fix the photographing device 15, and then turn on the photographing device 15 to take pictures of the area where the servo surface and the marking line are located.
