Description

Technical Field

[0001] The present application relates to the field of infrared detection, and in particular to a material winding direction detection method using an infrared sensor. Background Art

[0002] At present, the new coil equipment can operate in both directions of winding and unwinding. After unwinding, there is no need for the operator to unload the inner cylinder in the middle of the coil, which can be directly used for subsequent winding actions. It reduces the need for operators to enter the equipment, making it safer and more intelligent.

[0003] In the prior art, the infrared sensor is used for edge detection technology by collecting the current change generated by the infrared receiving end and then outputting the signal to the controller. Usually, the collected signal is output through a filtering algorithm in the algorithm, and the direction of the coil is not judged by the input signal and provided to the controller. This technology cannot define which end is the winding tension controller and the unwinding tension controller, so the corresponding control parameters cannot be used. Summary of the invention

[0004] In order to enable the tension controllers at both ends of the production line to realize the conversion between winding and unwinding functions, the present application provides a material winding direction detection method using an infrared sensor.

[0005] In a first aspect, the present application provides a material winding direction detection method using an infrared sensor, comprising the following steps: A plurality of current signals to be detected are generated based on the infrared sensor, and the plurality of current signals to be detected are input into a processing chip; The processing chip analyzes several current signals to be detected, extracts the fluctuating part of the current signals to be detected, and obtains the signal of the winding material direction; The processing chip transmits the signal of the winding material direction to the tension controller.

[0006] By adopting the above technical solution, the processing chip can identify whether the input signal change should trigger the signal to change the tension controller parameters, so that the tension controller can switch between the winding parameters and the unwinding parameters. The controller can issue execution action instructions more accurately, thereby achieving full automation without the need for an operator to unload the inner tube after unwinding.

[0007] Optionally, the infrared sensor generates a plurality of current signals to be detected, and before the plurality of current signals to be detected are input into the processing chip, the following steps are included: Call order data to obtain parameters for fluctuations in material defects; Based on the material fluctuation parameters, the infrared sensor threshold is set.

[0008] By adopting the above technical solution, if there is material blocking the sensing area of ​​the infrared sensor, the material fluctuates and the range is larger than the designed detection area, this situation will cause an erroneous output. Therefore, before setting the infrared sensor, the sensing threshold corresponding to the infrared sensor can be adjusted based on the material fluctuation parameters to adapt to larger irregular situations.

[0009] Optionally, setting the infrared sensor threshold based on the material fluctuation parameter includes the following steps: Adjust the distance between infrared sensors to obtain the maximum detection range parameters; If the maximum detection range parameter satisfies the material fluctuation parameter, confirm the setting of the infrared sensor threshold; If the maximum detection range parameter does not meet the material fluctuation parameter, add an infrared sensor and reset the infrared sensor threshold.

[0010] By adopting the above technical solution, when the maximum detection range parameters meet the material fluctuation parameters, it is only necessary to adjust the spacing between the infrared sensors to increase the overall detection range, thereby reducing the necessity of adding infrared sensors and indirectly saving costs.

[0011] Optionally, the processing chip analyzes a plurality of current signals to be detected, extracts a fluctuating portion of the current signals to be detected, and obtains a signal of the direction of the winding material, including the following sub-steps: Calibrate a number of current signals to be detected; Acquire a number of current signal parameters, pair the current parameters in pairs, and acquire a number of pairing groups; Calculating the differences between the current parameters in a plurality of paired groups to obtain a plurality of signal differences; When the difference values ​​of several signals are all smaller than the preset value, it is confirmed that the signal of the winding material direction is obtained, and the signal corresponding to the winding material direction is the original winding direction; If there is a signal difference greater than a preset value, the position information of the corresponding current signal to be detected is analyzed and obtained, and the signal of the direction of the winding material is obtained accordingly.

[0012] By adopting the above technical solution, the calibration and direction detection of the current signal are realized, allowing the winding and unwinding switching functions of the production line, which helps to reduce the risks of operators, improve the degree of automation and production efficiency, and provide a safe production line environment.

[0013] Optionally, if there is a signal difference greater than a preset value, analyzing and obtaining the position information corresponding to the current signal to be detected, and correspondingly obtaining the signal of the winding material direction, includes the following sub-steps: Based on the ratio between a plurality of signal differences and a preset value, a plurality of paired groups are extracted, and corresponding common features, that is, the current signal to be detected existing in each group, are obtained; Based on the ratio between a plurality of signal differences and a preset value, a plurality of pairing groups are extracted to obtain corresponding missing features, that is, the current signal to be detected that does not exist in each group; The common features and the missing features are compared. If the common features and the missing features are consistent, it is confirmed that the position information of the corresponding current signal to be detected is obtained, and the signal of the direction of the winding material is obtained accordingly.

[0014] By adopting the above technical solution, the above steps can relatively accurately locate and obtain the position information of the current signal to be detected, and then obtain the corresponding signal of the winding material direction. At the same time, the reliability and accuracy of the current signal detection can be improved.

[0015] Optionally, the method of calibrating a plurality of current signals to be detected comprises the following steps: The current signal to be detected with the smallest current sent into the receiving end of the infrared sensor is marked as a zero value; The current signal to be detected with the largest current sent into the receiving end of the infrared sensor is marked as the full-scale value; Several infrared sensors are placed at zero value and full scale value for comparison to achieve calibration.

[0016] Optionally, after the processing chip transmits the signal of the winding material direction to the tension controller, the following steps are included: Get the parameters of the tension sensor for switching between rewinding and unwinding; generating an alarm signal; Send alarm signals and location information to the administrator terminal.

[0017] By adopting the above technical solutions, the response speed, monitoring capability and problem handling efficiency in production work are improved, which helps to ensure the reliability and safety of the production process and reduce losses caused by potential problems.

[0018] In a second aspect, the present application provides a material winding direction detection system using an infrared sensor, which adopts the following technical solution: include: A current signal input module is used to generate a plurality of current signals to be detected based on an infrared sensor, and the plurality of current signals to be detected are input into a processing chip; The signal acquisition module in the winding material direction is used to process the chip to analyze a number of current signals to be detected, extract the fluctuating part of the current signal to be detected, and obtain the signal in the winding material direction; The signal sending module of the winding material direction is used for processing the chip to transmit the signal of the winding material direction to the tension controller.

[0019] By adopting the above technical solution, the processing chip can identify whether the input signal change should trigger the signal to change the tension controller parameters, so that the tension controller can switch between winding parameters and unwinding parameters. The controller can issue execution action instructions more accurately, thereby achieving full automation without the need for operators to unload the inner tube after unwinding, and improving production efficiency.

[0020] In a third aspect, the present application provides an electronic device, which adopts the following technical solution: An electronic device comprises a memory, a processor and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, the steps of the material winding direction detection method using an infrared sensor as described in any one of the above items are implemented.

[0021] In a fourth aspect, the present application provides a computer storage medium, which adopts the following technical solution: A computer storage medium comprises a memory, a processor and a computer program stored in the memory and executable on the processor, wherein when the processor executes the computer program, the steps of the material winding direction detection method using an infrared sensor as described in any one of the above items are implemented.

[0022] In summary, this application includes the following beneficial technical effects: The processing chip can identify whether the input signal change should trigger the signal to change the tension controller parameters, so that the tension controller can switch between winding parameters and unwinding parameters. The controller can issue execution instructions more accurately, thus achieving full automation without the operator unloading the inner tube after unwinding, and improving production efficiency. If the infrared sensor's sensing area is blocked by materials, or the material fluctuates and the range is larger than the area designed for detection, this will cause an erroneous output. Therefore, before setting up the infrared sensor, the corresponding sensing threshold of the infrared sensor can be adjusted based on the material fluctuation parameters to adapt to a variety of fluctuation situations; When the maximum detection range parameters meet the material fluctuation parameters, it is only necessary to adjust the distance between infrared sensors to increase the overall detection range, reducing the need to add infrared sensors and indirectly saving costs.

[0029] The following is combined with Figure 1-Figure 6 This application is described in further detail.

[0030] Reference Figure 1 The present application discloses a material winding direction detection method using an infrared sensor, comprising the following steps: S1: Generate a number of current signals to be detected based on the infrared sensor, and input the current signals to be detected into the processing chip.

[0031] It should be noted that the infrared sensor in the embodiment of the present application has a receiving end and a transmitting end. The current generated by the infrared receiving end is collected by the processing chip, and the current signal is collected into the processing chip through the ADC circuit.

[0032] By using processing chips and ADC circuits, the raw infrared signal can be converted into digital form, allowing for more complex signal processing and analysis. It helps to extract more information about the infrared signal, such as frequency, amplitude, and waveform, to meet the needs of different applications.

[0033] At the same time, the ADC circuit can better adjust the sampling rate, resolution and range of the signal in the direction of the winding material to meet the requirements of specific applications, providing greater flexibility and accuracy. Using the ADC circuit to convert analog signals into digital signals can reduce the complexity of the circuit. Digital signals are easy to process and integrate into digital systems, which helps to reduce costs and power consumption.

[0034] Furthermore, after step S1, the following steps are also included: S2: The processing chip analyzes a plurality of current signals to be detected, extracts the fluctuating part of the current signals to be detected, and obtains the signal of the winding material direction.

[0035] Reference Figure 2, step S2 includes the following sub-steps: S21: Calibrate a plurality of current signals to be detected.

[0036] Reference Figure 3 , step S21 includes the following sub-steps: S211: Mark the current signal to be detected with the smallest current sent to the receiving end of the infrared sensor as a zero value.

[0037] S212: Mark the current signal to be detected with the largest current sent into the receiving end of the infrared sensor as the full-scale value.

[0038] S213: several infrared sensors are placed at zero value and full scale value for comparison to achieve calibration.

[0039] In this embodiment, it is assumed that three groups of infrared sensors are used to detect foreign objects. The transmitting end of the infrared sensor uses three rows of infrared transmitting lamps, and the receiving end of the infrared sensor correspondingly uses three rows or infrared receivers. The receiving end of the processing chip can generate three current change values. Now assume that it is ordinary fluctuation detection, and the signals used are A, B and C respectively.

[0040] The corresponding calibration is as follows: After the processing chip can collect the signal, the first thing to do is to calibrate the A, B and C signals. That is, let the processing chip mark the zero position (the sensing area is completely blocked, the receiving end current is the minimum) and full scale (the sensing area is not blocked, the receiving end current is the maximum) of each group of signals.

[0041] Correspondingly, the signal to be detected with the smallest current amount received by the infrared sensor is marked as a zero-position value, and the zero-position value is matched with the actual current signal to ensure the accuracy of subsequent measurements.

[0042] At the same time, the signal to be detected with the largest current received by the infrared sensor is marked as the full-scale value, and the measurement range of the sensor is determined, so that the signal within the normal operating range can be accurately measured.

[0043] Therefore, it is ensured that the infrared sensor can accurately measure the current signal to be detected and correspond the measurement result to the actual signal strength.

[0044] Replay Figure 2 , step S2 also includes the following sub-steps: S22: Acquire a plurality of current signal parameters, and pair the plurality of current parameters in pairs to acquire a plurality of pairing groups.

[0045] S23: Calculate the differences between the current parameters in a plurality of paired groups to obtain a plurality of signal differences.

[0046] S24: When the differences of the plurality of signals are all smaller than the preset values, it is confirmed that the signal of the winding material direction is obtained, and the signal corresponding to the winding material direction is the original winding direction.

[0047] It should be noted that, taking the three signals A, B and C as an example, after corresponding calibration, three current values, namely a, b and c, are obtained, and the differences between the three values, namely ab, bc and ac, are compared accordingly, and then it is determined whether the material winding direction is from a to b to c, or from c to b to a.

[0048] Among them, when the difference between the three groups of signals a, b and c is very small, there is material blocking the sensing area of ​​the infrared sensor, the edge of the material is neat and has no fluctuations, and the material is in a 90-degree position relationship with the sensor without tilt or with a tilt that does not exceed the threshold. In this case, the direction of the material does not change, and the tension controllers for winding and unwinding maintain the existing parameters.

[0049] In addition, the following situations also exist: The infrared sensor's sensing area is blocked by material, the material fluctuates, and the range is larger than the area designed for detection. This situation will cause erroneous output.

[0050] Corresponding, refer to Figure 4 , before step S2, the following steps are also included to solve the above problems.

[0051] A1: Call the order data to obtain the parameters of the material defect fluctuation problem.

[0052] A2: Set the infrared sensor threshold based on the material fluctuation parameters.

[0053] Because the infrared sensor's sensing area is blocked by materials, the material fluctuates and the range is larger than the designed detection area, this situation will cause erroneous output. Therefore, before setting up the infrared sensor, the sensing threshold of the infrared sensor can be adjusted based on the material fluctuation parameters to adapt to larger irregular situations.

[0054] Reference Figure 5 , step A2 further comprises the following steps: A21: Adjust the distance between infrared sensors to obtain the maximum detection range parameters.

[0055] A22: If the maximum detection range parameter satisfies the material fluctuation parameter, confirm the setting of the infrared sensor threshold.

[0056] A23: If the maximum detection range parameter does not meet the material fluctuation parameter, add an infrared sensor and reset the infrared sensor threshold.

[0057] Therefore, when the maximum detection range parameters meet the material fluctuation parameters, it is only necessary to adjust the distance between the infrared sensors to improve the overall detection range, reducing the necessity of adding infrared sensors and indirectly saving costs.

[0058] Replay Figure 2 , step S2 also includes the following sub-steps: S25: If there is a signal difference greater than a preset value, the position information of the current signal to be detected is analyzed and obtained, and the signal of the winding material direction is obtained accordingly.

[0059] Reference Figure 6 , step S25 includes the following sub-steps: S251: extracting a plurality of pairing groups based on the ratio between a plurality of signal differences and a preset value, and correspondingly obtaining common features, that is, the current signal to be detected existing in each group.

[0060] S252: extracting a plurality of pairing groups based on the ratios between a plurality of signal differences and a preset value, and correspondingly obtaining missing features, that is, current signals to be detected that do not exist in each group.

[0061] S253: Compare the common features with the missing features. If the common features are consistent with the missing features, confirm that the position information of the current signal to be detected is obtained, and the signal of the direction of the winding material is obtained accordingly.

[0062] Correspondingly, the above steps can relatively accurately locate and obtain the position information of the current signal to be detected, and then obtain the corresponding signal of the winding material direction, and at the same time, can improve the reliability and accuracy of the current signal detection.

[0063] Similarly, taking the three sets of values ​​a, b and c as an example, the details are as follows: When the difference between the two groups of signals a and b and a and c is large, and the difference between b and c is small, the following situation will occur: There is material in the sensing area of ​​the infrared sensor, the material is fluctuating and the position is a.

[0064] When the difference between the two groups of signals a and b and b and c is large, and the difference between a and c is small, the following situation will occur: There is material in the sensing area of ​​the infrared sensor, the material is fluctuating and the position is b.

[0065] When the difference between the two groups of signals a and c and b and c is large, and the difference between a and b is small, the following situation will occur: There is material in the sensing area of ​​the infrared sensor, the material is in the direction of material winding and the position is c.

[0066] Corresponding sequence, if the fluctuation is from a to b to c, the material is winding in one direction. If the fluctuation changes from c to b to a, the material is winding in the other direction. Configure the winding and unwinding parameters of the tension controller line according to the direction of the material.

[0067] Correspondingly, after step S3, the following steps are also included: S4: Switch the parameters of the winding and unwinding tension sensors.

[0068] S5: Generate an alarm signal.

[0069] S6: Send the alarm signal and location information to the administrator terminal.

[0070] Correspondingly, the response speed, monitoring capability and problem handling efficiency in production work are improved, which helps to ensure the reliability and safety of the production process and reduce losses caused by potential problems.

[0072] The signal acquisition module in the winding material direction is used to process the chip to analyze a number of current signals to be detected, extract the fluctuating part of the current signal to be detected, and obtain the signal in the winding material direction.

[0073] The signal sending module of the winding material direction is used for processing the chip to transmit the signal of the winding material direction to the tension controller.

[0074] Correspondingly, the processing chip can identify whether the input signal change should trigger the signal to change the tension controller parameters, so that the tension controller can switch between winding parameters and unwinding parameters. The controller can issue execution action instructions more accurately, thereby achieving full automation without the need for operators to unload the inner tube after unwinding, and improving production efficiency.
