Description

Technical Field

[0001] This invention relates to a method and system for automatically reading residual torsion data of steel cord, belonging to the field of machine tool display technology. Background Technology

[0002] Currently, the torsion value read by the ATC device of our twisting machine is a direct reading value of the digital torsion value. The technical department requires that the torsion data must be recorded according to the interval control standard (e.g., if the torsion is between 0.00 and 0.24, record the torsion as 0.00; if it is between 0.25 and 0.49, record the torsion as 0.25). Therefore, when recording the torsion information of the product, employees need to calculate and record the actual torsion value according to the interval requirements of the technical department. During the implementation process, due to the large amount of data, the error rate of employees is high, reaching more than 5%, which does not meet the machine tool ATC control requirements and standards. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method and system for automatically reading residual torsion data of steel cord. This system automatically maps the actual torsion value with the torsion technical control standard parameters to form a technical parameter library that matches the actual torsion value. The system automatically calculates and adjusts the torsion range value and displays it on the operation panel, avoiding manual calculation and conversion based on technical requirements and improving the accuracy of torsion data calculation.

[0004] To achieve the above objectives, the present invention is implemented using the following technical solution:

[0005] In a first aspect, the present invention provides a method for automatically reading residual torsion data of steel cord, comprising:

[0006] Obtain the standard parameters for the torsion control technology of steel cord, and automatically map them into a technical parameter library based on the relevant parameters;

[0007] The pre-calculated actual torsion value is matched with the technical parameter library;

[0008] The actual torsion value is replaced with the fixed torsion value corresponding to the technical setting standard range where the match is successful, and transmitted as the torsion range value to the operation panel for display.

[0009] Furthermore, the technical parameter library includes 10 positive and 10 negative values ​​in each of the technical setting standard ranges and 20 corresponding torsional fixed values.

[0010] Furthermore, the process of matching the pre-calculated actual torsion value with the technical parameter library includes:

[0011] The actual torsion value is sequentially and cyclically matched with 20 technical setting standard intervals. The actual torsion value falling into the technical setting standard interval is considered a successful match. The actual torsion value corresponding to the technical setting standard interval is transmitted to the operation panel as the torsion interval value for display.

[0012] When the actual torsion value being matched exceeds the range of the technical standard interval, the technical standard interval with the largest value compared to the actual torsion value will be taken as the interval of successful matching; or the technical standard interval with the smallest value compared to the actual torsion value will be taken as the interval of successful matching.

[0013] Furthermore, the method for obtaining the actual value of the torsion includes:

[0014] The real-time analog value of the steel cord's torsion is obtained using a distance sensor and converted into a real-time digital value of the torsion.

[0015] The difference between the average value of the real-time torsion digital value and the torsion digital value without torsion is calculated, and 1% of the difference is selected as the actual torsion value; wherein, the torsion digital value without torsion is the midpoint of the range of real-time torsion digital values.

[0016] Furthermore, the real-time torsional digital value D n The conversion calculation formula is:

[0017]

[0018] Among them, the real-time torsion digital value D n The range is 0-1000; A represents the nth real-time torsional analog value A, with a frequency of 10 times per second.

[0019] Furthermore, the difference between the calculated average value of the real-time torsion digital quantity and the torsion digital quantity without torsion is calculated, and 1% of the difference is selected as the calculation formula for the actual torsion value M.

[0020]

[0021] Where M represents the actual value of torsion; (D n +D n+1 +D n+2 +...D n+9 ) / 10 represents the average of the sum of ten consecutive real-time torsional digital values ​​read per second; L represents the torsional digital value when there is no torsional movement.

[0022] Secondly, the present invention provides an automatic system for reading residual torsion data of steel cord, including an operation panel and a PLC control module;

[0023] The operation panel includes a setting interface for inputting standard parameters for the torsion control technology of the steel cord;

[0024] The PLC control module is used to acquire the torsion technology control standard parameters and automatically map them into a technical parameter library; match the pre-calculated actual torsion value with the technical parameter library; replace the actual torsion value with the torsion fixed value corresponding to the technical setting standard range in the matched technical parameter library; and transmit it as the torsion range value to the operation panel for display.

[0025] Furthermore, the specific operation of the PLC control module is as follows:

[0026] The actual torsion value is sequentially and cyclically matched with 20 technical setting standard intervals. The actual torsion value falling into the technical setting standard interval is considered a successful match. The actual torsion value corresponding to the technical setting standard interval is transmitted to the operation panel as the torsion interval value for display.

[0027] When the actual torsion value being matched exceeds the range of the technical standard interval, the technical standard interval with the largest value compared to the actual torsion value will be taken as the interval of successful matching; or the technical standard interval with the smallest value compared to the actual torsion value will be taken as the interval of successful matching.

[0028] Furthermore, it also includes a distance sensor; the PLC control module is connected to the distance sensor, and the PLC control module uses the distance sensor to obtain the real-time analog value of the steel cord's torsion.

[0029] Furthermore, the operation of the PLC control module to obtain the actual value of the torsion includes:

[0030] The real-time analog value of the steel cord's torsion is obtained using a distance sensor and converted into a real-time digital value of the torsion.

[0031] The difference between the average value of the real-time torsion digital value and the torsion digital value without torsion is calculated, and 1% of the difference is selected as the actual torsion value; wherein, the torsion digital value without torsion is the midpoint of the range of real-time torsion digital values.

[0032] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0033] This invention provides a method for dynamically reading residual torsion data of steel cord. It utilizes standard parameters for acquiring torsion control technology of the steel cord and automatically maps these parameters to form a technical parameter library. The pre-calculated actual torsion value is matched against the technical parameter library. The actual torsion value is then replaced with a fixed torsion value corresponding to the matched technical standard interval, which is transmitted as the torsion interval value to the operation panel for display. This method automatically adjusts the torsion data according to the technical standard interval to obtain the required torsion interval value, avoiding serious errors in manual reading, comparison, calculation, and recording processes due to excessive data volume. It significantly improves the torsion control standard and the accuracy of the torsion data. Attached Figure Description

[0034] Figure 1 This invention provides a flowchart of a method for automatically reading residual torsion data of steel cord.

[0035] Figure 2 for Figure 1 A detailed workflow diagram. Detailed Implementation

[0036] A steel cord (wire rope) of a specified length, with one end fixed and the other end rotating freely, has a number of rotations called residual torsion. The residual torsion is matched against a technically set standard range; the value corresponding to this range after matching is called the torsion fixation value.

[0037] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0038] Example 1:

[0039] See Figure 1 and Figure 2 This embodiment provides a method for automatically reading residual torsion data of steel cord, which specifically includes the following steps:

[0040] Step 1: Obtain the standard parameters for the torsion control technology of steel cord, and automatically map them into a technical parameter library based on the relevant parameters.

[0041] Step 2: Match the pre-calculated actual torsion value with the technical parameter library.

[0042] Step 3: Replace the actual torsion value with the fixed torsion value corresponding to the technical setting standard range where the match was successfully established, and transmit it as the torsion range value to the operation panel for display.

[0043] The technical parameter library, which is automatically mapped based on relevant parameters, includes 10 positive and 10 negative technical setting standard intervals. Each technical setting standard interval corresponds to a fixed torsional value. Therefore, it contains a total of 20 fixed torsional values, each corresponding to a technical setting standard interval.

[0044] Therefore, the implementation process of step two specifically includes:

[0045] (1) The actual value of the torsion is sequentially matched with 20 technical setting standard intervals in a step-by-step cycle.

[0046] (2) If the actual torsion value falls within a certain technical setting standard range, it is considered a successful match. The actual torsion value is transmitted to the operation panel as the torsion range value corresponding to the technical setting standard range for display.

[0047] When the matched actual torsion value exceeds the range of its various technical setting standard intervals, there are two situations: First, the largest technical setting standard interval compared to the actual torsion value is taken as the successfully matched interval (the actual torsion value is larger than the data in the largest technical setting standard interval). In this case, the fixed torsion value corresponding to the largest technical setting standard interval is selected and transmitted to the operation panel as the torsion interval value for display.

[0048] Second, the smallest technical setting standard range compared to the actual torsion value is taken as the successfully matched range (the actual torsion value is smaller than the data in the smallest technical setting standard range). At this time, the fixed torsion value corresponding to the smallest technical setting standard range is selected and transmitted to the operation panel as the torsion range value for display.

[0049] Optional methods for obtaining the actual value of the torsion include:

[0050] (1) Use a distance sensor to obtain the real-time analog value of the steel cord torsion and convert it into a real-time digital value of the torsion.

[0051] (2) The average value of the real-time torsion digital value is calculated and the torsion digital value without torsion is compared. 1% of the difference is selected as the actual torsion value. The torsion digital value without torsion is selected as the median value of the real-time torsion digital value range.

[0052] Real-time torsion of digital value D n The conversion calculation formula is:

[0053] Among them, the real-time torsion digital value D n The range is 0-1000; A represents the nth real-time torsional analog value A, with a frequency of 10 times per second.

[0054] The formula for calculating the difference between the average value obtained by calculating the real-time torsional digital quantity and the torsional digital quantity without torsion, and selecting 1% of the difference value as the actual torsional value M is:

[0055]

[0056] Among them, M represents the actual torsional value; (Dn + Dn+1 + Dn+2 +... Dn+9) / 10 represents the average value of the sum of ten consecutive real-time torsional digital quantities read per second; L represents the torsional digital quantity without torsion.

[0057] Example 2:

[0058] This embodiment provides a specific implementation plan, which is specifically referred to the following list.

[0059] In Table 1, the corresponding relationship between the real-time torsional analog quantity and the torsional digital quantity obtained by using the distance sensor is given. In formula (1), A is the analog signal quantity value received by the distance sensor (unit: V), D is the digital quantity value corresponding to the analog signal quantity value. According to formula (1) of Example 1, the torsional digital quantity values are calculated as shown in Table 2.

[0060]

[0061] Table 1

[0062] As follows, Table 2 gives the torsional digital quantity values sampled continuously 10 times per second and the torsional digital quantity value without torsion. According to formula (2) in Example 1, the actual torsional average value per second is calculated and defaulted as the actual torsional value. The torsional digital quantity value without torsion takes the middle value 500 of the real-time torsional digital quantity value range.

[0063]

[0064]

[0065] Table 2 is as follows, Table 3 shows the torsional interval values, including but not limited to the ranges in the table.

[0066]

[0067]

[0068] When the condition a < M < b holds, take the torsional fixed value I as the torsional interval value;

[0069] When the condition a < M < b does not hold, continue to match b < M < c. If it holds, take the torsional fixed value J as the torsional interval value;

[0070] When the above conditions are not met, loop and match until M C, and take the corresponding torsional fixed value of the torsional technology setting interval standard a, or take the corresponding torsional fixed value of the torsional technology setting interval standard c as the torsional interval value.

[0073] Operation panel: A setting interface for inputting the torsional technology control standard parameters of the steel cord.

[0074] PLC control module: Used to obtain the torsional technology control standard parameters, automatically map and form a technology parameter library according to the relevant parameters; match the pre-calculated actual torsional value with the technology parameter library; replace the actual torsional value with the torsional fixed value corresponding to the technology setting standard interval where the match is successful, and transmit it as the torsional interval value to the operation panel for display.

[0075] Specifically, the PLC control module operates as follows:

[0076] Match the actual torsional value step by step and loop with 20 of the technology setting standard intervals in sequence;

[0077] Regard the technology setting standard interval where the actual torsional value falls as a successful match. The actual torsional value will take the torsional fixed value corresponding to its technology setting standard interval, and transmit this torsional fixed value as the torsional interval value to the operation panel for display.

[0078] When the matched actual torsional value exceeds the range of all technology setting standard intervals, regard the largest technology setting standard interval compared with its actual torsional value as the successfully matched interval, and transmit the torsional fixed value of the largest technology setting standard interval as the torsional interval value to the operation panel for display. Or regard the smallest technology setting standard interval compared with the actual torsional value as the successfully matched interval, and transmit the torsional fixed value of the smallest technology setting standard interval as the torsional interval value to the operation panel for display.

[0079] Optionally, the automatic system for reading the residual torsional data of steel cord further includes a distance sensor. The PLC control module is connected to the distance sensor and is used to obtain the real-time torsional analog value of the steel cord obtained by the distance sensor.

[0080] The specific operation of the PLC control module to obtain the actual torsional value includes the following:

[0081] (1) The distance sensor obtains the real-time torsional analog value of the steel cord, which is obtained through the PLC control module and converted into a real-time torsional digital value.

[0082] (2) The PLC control module calculates the average value of the sum of ten consecutive real-time torsional digital values ​​received per second, and calculates the difference between this average value and the torsional digital value when there is no torsion, and selects 1% of the difference value as the actual torsion value. Among them, the torsional digital value when there is no torsion is the midpoint of the range of real-time torsional digital values.
