Description

Technical Field

[0001] The present invention relates to the technical field of data processing, and in particular to an optimization method, equipment and medium for a sensor of a resistive flexible fabric. Background Art

[0002] Agricultural haul hoses frequently bend during service. When bent to their limit, they can become kinked, a sharp, irreversible deformation smaller than their diameter. This irreversible deformation causes the hose's PU and polyester reinforcement layers to separate, leading to stress concentration in the outer covering and increased wear and leakage. Since hoses aren't constantly measured for bending radius during farm use to prevent kinking, existing technologies employ embedded sensors with external signal output terminals to provide real-time visibility of bending conditions and extend the hose's service life. For example, the paper "Design and Analysis of Flexible Strain Sensors Based on Woven Structures" published in the Journal of Sensor Technology, Vol. 21, No. 7, July 2008, demonstrates this approach. This approach integrates sensors with water hoses, directly embedding sensing elements within plain or twill woven fabrics to avoid post-processing damage to the mechanical properties of both the fabric and the hose. However, this approach also presents technical challenges: Only series or parallel resistor fabric sensors can be embedded within the woven fabric, and the accuracy of angle prediction for deformation types varies depending on the resistor fabric connection method. Summary of the Invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: According to a first aspect of the present invention, a method for optimizing a resistive flexible fabric sensor is provided.

[0011] Example 1 The first embodiment of the present invention provides a method for optimizing a sensor of a resistive flexible fabric, such as Figure 1 As shown, the method is used to detect the curvature change of a hose in which a sensor of a target resistance flexible fabric is embedded, and the method comprises the following steps: S001, when the target resistive flexible fabric sensor is a parallel resistive flexible fabric sensor, execute S002.

[0012] Specifically, the series-type resistive flexible fabric sensor is constructed as follows: the odd-numbered weft yarns of the woven fabric are conductive elastic yarns, the even-numbered weft yarns and all the warp yarns are insulating elastic yarns, and the leading and trailing ends of the conductive elastic weft yarns are serially connected to form a continuous yarn. The parallel-type resistive fabric sensor is constructed as follows: all weft yarns and the first and nth warp yarns of the woven fabric are conductive elastic yarns, and the remaining n-2 warp yarns, excluding the first and nth warp yarns, are insulating elastic yarns. The leading or trailing end of each conductive elastic weft yarn is connected to the first or nth warp yarn, with a total of n warp yarns.

[0013] In one embodiment of the present invention, Figure 2 As shown, the parallel resistance fabric sensor has weft yarns in the horizontal direction and warp yarns in the vertical direction. The dotted lines represent conductive elastic yarns, while the solid lines represent insulating yarns. All weft yarns (i.e., W1 to Wm) and the first and nth warp yarns (i.e., J1 and Jn) of the woven fabric are conductive elastic yarns, while the remaining n-2 warp yarns (i.e., J2, J3, ..., Jn-1) are insulating elastic yarns. The leading or trailing end of each conductive elastic weft yarn is connected to the first warp yarn (i.e., J1) or the nth warp yarn (i.e., Jn), with a total of n warp yarns. This parallel resistance fabric sensor forms part of a fabric.

[0014] In one embodiment of the present invention, Figure 3As shown in the figure, in a series-type resistive fabric sensor, the horizontal direction is weft yarn, and the vertical direction is warp yarn. The dotted lines represent conductive elastic yarns, while the solid lines represent insulating yarns. Wi represents the i-th weft yarn, where i ranges from 1 to m, and m is the number of weft yarns. Jj represents the j-th warp yarn, where j ranges from 1 to n, and n is the number of warp yarns. The odd-numbered weft yarns (i.e., W1, W3, W5, etc.) of the resistive fabric (i.e., W1, W3, W5, etc.) are conductive elastic yarns, while the even-numbered weft yarns (i.e., W2, W4, W6, etc.) of the resistive fabric (i.e., W2, W4, W6, etc.) are insulating elastic yarns. All warp yarns are insulating elastic yarns. The leading and trailing ends of each conductive elastic weft yarn are serially connected using a folded edge to form a continuous yarn.

[0015] Specifically, a parallel-type resistive fabric sensor comprises: all weft yarns of the resistive fabric are conductive elastic yarns; the first and nth warp yarns of the resistive fabric are conductive elastic yarns; and the n-2 warp yarns other than the first and nth warp yarns are insulating elastic yarns. The leading or trailing end of each conductive elastic weft yarn is closely connected to the first or nth conductive elastic warp yarn. In one embodiment of the present invention, the leading or trailing end of each conductive elastic weft yarn is bonded to the first or nth conductive elastic warp yarn using conductive adhesive.

[0016] S002: Apply a constant current source to the target resistance flexible fabric to obtain a specified output voltage of the target resistance flexible fabric. It can be understood that when bending occurs, the conductive yarn is strained, the resistance changes, and the specified output voltage changes.

[0017] S003: Determine the initial parallel curvature change at the designated bend of the hose based on the designated output voltage of the target resistance flexible fabric. Those skilled in the art will appreciate that any prior art method for determining the initial parallel curvature change based on the designated output voltage falls within the scope of the present invention.

[0018] S004: When the bending type of the designated bending position is axial single-point deformation, the initial parallel curvature change is used as the target parallel curvature change.

[0019] S005: When the bend type at the designated bend is radial unilateral deformation, an intermediate bend angle is determined based on the initial parallel curvature change, and a target parallel curvature change is determined based on the initial parallel curvature change and the radial-parallel-serial correction value corresponding to the intermediate bend angle. It will be appreciated that the detection of radial unilateral deformation by a parallel-type resistive flexible fabric sensor is less accurate than that by a series-type resistive flexible fabric sensor. Therefore, the initial associated curvature change is compensated for based on the radial-parallel-serial correction value corresponding to the intermediate bend angle to determine the target parallel curvature change.

[0020] Specifically, based on the initial parallel curvature change and the radial-parallel-serial correction value corresponding to the intermediate bending angle, the target parallel curvature change is determined, specifically including: The target parallel curvature change is equal to the sum of the initial parallel curvature change and the radial-parallel-serial correction value corresponding to the intermediate bending angle.

[0021] In summary, when the sensor of the target resistance flexible fabric is a parallel resistance flexible fabric sensor, a constant current source is applied to the target resistance flexible fabric to obtain the specified output voltage of the target resistance flexible fabric, and the initial parallel curvature change of the specified bend of the hose is determined based on the specified output voltage of the target resistance flexible fabric. When the bending type of the specified bend is axial single-point deformation, the initial parallel curvature change is used as the target parallel curvature change. When the bending type of the specified bend is radial unilateral deformation, the intermediate bending angle is determined based on the initial parallel curvature change. Based on the initial parallel curvature change and the radial-parallel correction value corresponding to the intermediate bending angle, the target parallel curvature change is determined. The present invention can more accurately obtain the target parallel curvature change under the parallel resistance flexible fabric sensor.

[0022] Specifically, in S005, the radial-parallel-serial correction value corresponding to the intermediate bending angle is determined through the following steps: S051. Obtain designated training data, where the designated training data includes a first radial curvature change list B1={B11, B12, …, B1g, …, B1m} and a second radial curvature change list B2={B21, B22, …, B2g, …, B2m}, where B1g is a curvature change determined by a voltage output by a constant current source applied to a first hose embedded with a parallel resistor flexible fabric at g real bending angles of radial unilateral deformation; and B2g is a curvature change determined by a voltage output by a constant current source applied to a second hose embedded with a series resistor flexible fabric at g real bending angles of radial unilateral deformation. The value range of g is 1 to z, where z is the number of real bending angles.

[0023] S052 , obtaining a third radial curvature change list B0 = {B01, B02, …, B0g, …, B0m}, where the third radial curvature change B0g = B2g − B1g.

[0024] S053, setting a designated sliding window with a fixed bending angle. When only one designated sliding window meets the preset smooth condition, the designated sliding window is used as the designated angle interval; when several adjacent designated sliding windows all meet the preset smooth condition, the angles covered by the several adjacent designated sliding windows are used as the designated angle interval.

[0025] The designated sliding window satisfies a preset stationary condition, specifically: an average value of the third radial curvature change within the designated sliding window is less than a preset threshold.

[0026] S054: Obtain an average value t0 of the third radial curvature changes of all real bending angles in the specified angle range.

[0027] S055: If the intermediate bending angle is within the specified angle range, the radial-parallel-serial correction value corresponding to the intermediate bending angle is t0.

[0028] In summary, designated training data is obtained, a list of third radial curvature changes is obtained, and a designated sliding window with a fixed bending angle is set. When only one designated sliding window meets the preset stability condition, the designated sliding window is used as the designated angle interval; when several adjacent designated sliding windows all meet the preset stability condition, the angles covered by the several adjacent designated sliding windows are used as the designated angle interval, and the average value t0 of the third radial curvature changes of all real bending angles in the specified angle interval is obtained. If the middle bending angle is in the specified angle interval, the radial-parallel-serial correction value corresponding to the middle bending angle is t0. The present invention uses the difference between the parallel resistance flexible fabric and the series resistance flexible fabric under radial unilateral deformation. When the difference is stable within a certain range, the difference is used as the compensation value, so that the radial-parallel-serial correction value is more accurate.

[0029] Furthermore, S055 further includes: when the intermediate bending angle is not within the specified angle range, and there is only one specified angle range, executing the following steps: When the middle bending angle is smaller than the left endpoint of the specified angle range, the radial-parallel correction value corresponding to the middle bending angle is the product of the first weight factor and t0, and the first weight factor is equal to the quotient of the first specified difference and the left endpoint, and the first specified difference is the difference between the left endpoint and the middle bending angle.

[0030] When the middle bending angle is greater than the right endpoint of the specified angle range, the radial-parallel correction value corresponding to the middle bending angle is the product of the second weight factor and t0, the second weight factor is equal to the quotient of the second specified difference and the right endpoint, and the second specified difference is the difference between the middle bending angle and the right endpoint.

[0031] Furthermore, S055 further includes: when the intermediate bending angle is not within the specified angle range, and the number of the specified angle ranges exceeds one, executing the following steps: Calculate the distance between the middle bending angle and the left and right endpoints of each specified angle interval, and obtain the endpoint corresponding to the minimum distance, which is the specified endpoint.

[0032] Obtain the radial-parallel-serial correction value corresponding to the intermediate bending angle. The radial-parallel-serial correction value is the product of the third weight factor and t0. The third weight factor is equal to the quotient of the third specified difference and the specified endpoint. The third specified difference is the absolute value of the difference between the intermediate bending angle and the specified endpoint.

[0033] In summary, the weight is determined by the difference between the intermediate bending angle and the specified angle range, so as to more accurately determine the radial-parallel-serial correction value.

[0034] Example 2 A second embodiment of the present invention provides a method for detecting sensor parameters of a resistive flexible fabric. When the target resistive flexible fabric sensor is a series resistive flexible fabric sensor, S200 is executed.

[0035] S200: Apply a constant current source to the target resistance flexible fabric to obtain a target output voltage of the target resistance flexible fabric. It can be understood that when bending occurs, the conductive yarn is strained, the resistance changes, and the target output voltage changes.

[0036] S300: Determine the initial series curvature change at the target bend of the hose based on the target output voltage of the target resistance flexible fabric. Those skilled in the art will appreciate that any prior art method for determining the initial series curvature change based on the target output voltage falls within the scope of the present invention.

[0037] S400: When the bend type at the target bend is radial single-point deformation, the initial series curvature change is used as the target series curvature change. It can be understood that a series-type resistive flexible fabric sensor is relatively more accurate in detecting radial single-point deformation, while a parallel-type resistive flexible fabric is relatively more accurate in detecting axial single-point deformation. Therefore, when the series-type resistive flexible fabric detects radial single-point deformation, the initial series curvature change is directly used as the target series curvature change.

[0038] At step S500, when the bend type at the target bend is axial unilateral deformation, an initial bend angle is determined based on the initial series curvature change, and a target series curvature change is determined based on the initial series curvature change and the axial series-parallel correction value corresponding to the initial bending angle. It will be appreciated that detection of axial unilateral deformation using a series-type resistive flexible fabric sensor is less accurate than detection of axial unilateral deformation using a parallel-type resistive flexible fabric sensor. Therefore, an axial series-parallel correction value corresponding to the initial bending angle is determined to compensate for the inherited series curvature change.

[0039] The target series curvature change is determined based on the initial series curvature change and the axis series correction value corresponding to the initial bending angle, specifically including: The target series curvature change is equal to the sum of the initial series curvature change and the axis series correction value corresponding to the initial bending angle.

[0040] In summary, when the sensor of the target resistive flexible fabric is a series resistive flexible fabric sensor, a constant current source is applied to the target resistive flexible fabric to obtain the target output voltage of the target resistive flexible fabric, and the initial series curvature change of the target bend of the hose is determined based on the target output voltage of the target resistive flexible fabric. When the bending type of the target bend is radial single-point deformation, the initial series curvature change is used as the target series curvature change. When the bending type of the target bend is axial unilateral deformation, the initial bending angle is determined based on the initial series curvature change. Based on the initial series curvature change and the axial series-parallel correction value corresponding to the initial bending angle, the target series curvature change is determined. Based on the type and bending angle of the resistive flexible fabric sensor, the accuracy of the target series curvature change is improved.

[0041] Specifically, in S500, the axis string correction value corresponding to the initial bending angle is determined through the following steps: S510. Obtain target training data, where the target training data includes a first axial curvature change list A1={A11, A12, …, A1g, …, A1m} and a second axial curvature change list A2={A21, A22, …, A2g, …, A2m}, where A1g is a curvature change determined by applying a voltage output by a constant current source to a first hose embedded with a parallel resistor flexible fabric at g real bending angles of axial unilateral deformation; A2g is a curvature change determined by applying a voltage output by a constant current source to a second hose embedded with a series resistor flexible fabric at g real bending angles of axial unilateral deformation; the value range of g is 1 to z, and g is the number of real bending angles.

[0042] S520 , obtaining a third axial curvature change list A0={A01, A02, …, A0g, …, A0m}, where the third axial curvature change A0g=A1g−A2g.

[0043] S530, set a target sliding window with a fixed bending angle. When only one target sliding window meets the preset smooth condition, the target sliding window is used as the smooth angle interval; when several adjacent target sliding windows all meet the preset smooth condition, the angles covered by the several adjacent target sliding windows are used as the smooth angle interval.

[0044] The target sliding window satisfies a preset stability condition, specifically: the average value of the third axial curvature change within the target sliding window is less than a preset stability threshold.

[0045] S530: Obtain an average value k0 of the third axial curvature changes of all real bending angles in the stable angle range.

[0046] S540: If the initial bending angle is in a stable angle range, the axis string correction value corresponding to the initial bending angle is k0.

[0047] Specifically, if there is more than one stable angle interval, the average value k0 of the third axial curvature changes of all real bending angles in the stable angle interval is calculated.

[0048] In summary, target training data is obtained, a list of third-axis curvature changes is obtained, and a target sliding window with a fixed bending angle is set. When only one target sliding window meets the preset stability condition, the target sliding window is used as the stable angle interval; when several adjacent target sliding windows all meet the preset stability condition, the angles covered by several adjacent target sliding windows are used as the stable angle interval, and the average value of the third-axis curvature changes of all real bending angles in the stable angle interval is obtained. If the initial bending angle is in the stable angle interval, the axial series-parallel correction value corresponding to the initial bending angle is k0. The difference between the series resistance flexible fabric sensor and the parallel resistance flexible fabric sensor under axial unilateral deformation is taken. When the difference is stable within a certain range, the difference is used as the compensation value to make the axial series-parallel correction value more accurate.

[0049] Furthermore, S540 further includes: when the initial bending angle is not in the stable angle interval and there is only one stable angle interval, executing the following steps: When the initial bending angle is smaller than the left endpoint of the stable angle range, the axis string correction value corresponding to the initial bending angle is the product of the first weight coefficient and k0, the first weight coefficient is equal to the quotient of the first target difference and the left endpoint, and the first target difference is the difference between the left endpoint and the initial bending angle.

[0050] When the initial bending angle is greater than the right endpoint of the stable angle range, the axis string correction value corresponding to the initial bending angle is the product of the second weight coefficient and k0, the second weight coefficient is equal to the quotient of the second target difference and the right endpoint, and the second target difference is the difference between the initial bending angle and the right endpoint.

[0051] Furthermore, S540 further includes: when the initial bending angle is not in the stable angle interval, and when the number of stable angle intervals exceeds one, executing the following steps: Calculate the distance between the initial bending angle and the left and right endpoints of each stable angle interval, and obtain the endpoint corresponding to the minimum distance as the target endpoint; Obtain the axis serial-parallel correction value corresponding to the initial bending angle. The axis serial-parallel correction value is the product of the third weight coefficient and k0. The third weight coefficient is equal to the quotient of the third target difference and the target endpoint. The third target difference is the absolute value of the difference between the initial bending angle and the target endpoint.

[0052] In summary, the weight is determined by the difference between the initial bending angle and the stable angle range, and the axis serial-parallel correction value is further determined to more accurately obtain the axis serial-parallel correction value when the initial bending angle is not in the stable angle range.

[0053] Example 3 A third embodiment of the present invention provides a sensor detection method for a resistive flexible fabric, the method further comprising: S101: Determine a first accuracy of the parallel sensor connection based on a number of target parallel curvature changes a and the actual parallel curvature changes b corresponding to each target parallel curvature change. Specifically, if a is within [bx, b+x], a is used as a first positive sample. The first accuracy is the ratio of the number of first positive samples to the number of target parallel curvature changes.

[0054] S102: Determine a second accuracy of the serial sensor connection based on a number of target serial curvature changes c and the actual serial curvature changes d corresponding to each target serial curvature change. If c is within [dy, d + y], use x as a second positive sample. The second accuracy is the ratio of the number of second positive samples to the number of target serial curvature changes.

[0055] Furthermore, after S102, the following steps are also included: S110 , applying a constant current source to the resistive flexible fabric to obtain an output fabric voltage of the resistive flexible fabric.

[0056] S120 , determining a first fabric curvature change at a fabric bend of the hose based on a fabric voltage of the resistive flexible fabric.

[0057] S130, when the fabric bend is circumferentially deformed, based on the first fabric curvature change and the first sensor connection mode of the resistive flexible fabric in the hose, determine the second fabric curvature change of the hose in the second sensor connection mode, the sensor connection mode being a parallel resistive flexible fabric sensor or a series resistive flexible fabric sensor, and the first sensor connection mode is different from the second sensor connection mode.

[0058] Specifically, if the first sensor connection method is a parallel resistance flexible fabric sensor, then the second sensor connection method is a series resistance flexible fabric sensor; if the first sensor connection method is a series resistance flexible fabric sensor, then the second sensor connection method is a parallel resistance flexible fabric sensor.

[0059] S140 , determining a target fabric change curvature based on the first fabric change curvature, the second fabric change curvature, the first accuracy rate, and the second accuracy rate.

[0060] Specifically, S140 also includes: S141, if the first sensor connection mode is a parallel resistive flexible fabric sensor, the target fabric change curvature is equal to the weighted sum of the first fabric change curvature and the second fabric change curvature, and the weight ratio of the first fabric change curvature to the second fabric change curvature is equal to the ratio of the second accuracy rate to the first accuracy rate.

[0061] S142, if the first sensor connection mode is a series resistive flexible fabric sensor, the target fabric change curvature is equal to the weighted sum of the first fabric change curvature and the second fabric change curvature, and the weight ratio of the first fabric change curvature to the second fabric change curvature is equal to the ratio of the first accuracy rate to the second accuracy rate.

[0062] In summary, a constant current source is applied to the resistive flexible fabric, the output fabric voltage of the resistive flexible fabric is obtained, and the first fabric curvature change at the fabric bend of the hose is determined based on the fabric voltage of the resistive flexible fabric. When the fabric bend is a circumferential deformation, the second fabric curvature change of the hose in the second sensor connection mode is determined based on the first fabric curvature change and the first sensor connection mode of the resistive flexible fabric in the hose. Based on the first fabric change curvature, the second fabric change curvature, the first accuracy rate and the second accuracy rate, the target fabric change curvature during circumferential deformation is more accurately determined.
