Description

TECHNICAL FIELD

[0001] Embodiments of the present specification relate to the technical field of deviation correction control, in particular to a width measurement and deviation correction method. BACKGROUND

[0002] In the existing deviation correction application scenarios, the online width measurement device usually attaches a material to the surface of a light source, places a linear array CCD industrial camera at a certain height, adjusts the angle, and the material is imaged on the CCD photosensitive element. Then, the accurate width size is obtained through calculation and processing, and the current material width is displayed on a large screen or a PLC industrial computer. However, the CCD camera has certain instability factors. Before the industrial CCD camera is adjusted, the appropriate focal length and aperture need to be selected according to different working scenarios. In addition, the detection light source selection and the light source installation environment also have an impact on the accuracy. After being used for a certain period of time, the CCD lens surface will be attached with a layer of difficult-to-clean oil stains due to long-term work in high temperature and other harsh environments.

Depending on the context, the word "if' as used herein can be interpreted as "when" or "upon" or "in response to determining".

[0054] In the present specification, a width measurement correction method is provided, and the present specification also relates to a width measurement correction device, a computing device, and a computer-readable storage medium, which are described in detail one by one in the following embodiments.

[0055] Referring to Figure 1 , Figure 1 A flowchart of a width measurement correction method according to one embodiment of the present specification is shown, which specifically includes the following steps.

[0056] Step 101: setting a web detection range of the correction sensor based on width information of the web to be measured.

[0057] The web detection range is an ideal shielding range of the web to be measured within the detection range of the correction sensor.

[0058] The correction sensor can be a high-precision infrared correction sensor, a high-precision laser correction sensor, or a high-precision photoelectric correction sensor.

[0059] In addition, at least one correction sensor is arranged at a first side of the web to be measured, at least one correction sensor is arranged at a second side of the web to be measured, and a correction controller corresponding to the correction sensor is arranged, wherein the first side can be understood as the left side of the web to be measured, and the second side can be understood as the right side of the web to be measured.

[0060] Specifically, the width information of the web to be measured is determined, and then the web detection range of the web to be measured within the field of view range of the correction sensor of the edge of the web to be measured is set based on the width information.

[0061] In one possible embodiment, when the width information of the web to be measured is determined to be 100, the web detection range corresponding to the at least one correction sensor at the first side of the web to be measured can be set to 20, and the web detection range corresponding to the at least one correction sensor at the second side of the web to be measured can be set to 20, wherein the web detection ranges of the correction sensors at the first side and the second side of the web to be measured can be the same or different.

[0062] And after setting the web detection range of the deviation correction sensor according to the width information of the to-be-measured web, the area where the web is not detected can be determined based on the web detection range, and the real-time web width of the to-be-measured web can be determined based on the aforementioned area information, and the specific implementation manner is as follows:

[0063] The method comprises the following steps of:

[0064] The method comprises the following steps of:

[0065] The web middle range can be understood as the area on the to-be-measured web that is not detected by the deviation correction sensor except the web detection range.

[0066] Specifically, after setting the web detection range of the deviation correction sensor based on the width information of the to-be-measured web, the web middle range that is not detected by the deviation correction sensor can be obtained by subtracting the sum of the web detection ranges of each deviation correction sensor from the width information of the to-be-measured web.

[0067] For example, when the width information of the to-be-measured web is determined to be 100, and the web detection ranges of the at least two deviation correction sensors located on both sides of the to-be-measured web are both 20, the web middle range can be calculated as 60 by subtracting the sum of the web detection ranges of the at least two deviation correction sensors, i.e. 40, from the width information 100.

[0068] Referring to Figure 2 , Figure 2 A web detection range schematic diagram of a width measurement and deviation correction method according to an embodiment of the present disclosure is shown.

[0069] As shown in the figure, Figure 2 a1 in the figure can be understood as the web detection range of the deviation correction sensor corresponding to the first side of the to-be-measured web, a2 can be understood as the web detection range of the deviation correction sensor corresponding to the second side of the to-be-measured web, and b can be understood as the web middle range that is not detected by the deviation correction sensor except a1 and a2. The value can be input by the controller according to the input of the width of the web on site minus the detection ranges of the two deviation correction sensors. If the to-be-measured web is a web of different models, the sensor with a larger detection range of the deviation correction sensor can be selected for width measurement. The controller can also reserve a change interface or communicate with the PLC, and a1+a2+b=the width information of the to-be-measured web.

[0070] Step 102: performing deviation correction detection on the to-be-measured web based on the web detection range, and generating a real-time web width value of the to-be-measured web based on the detection result.

[0071] Specifically, the roll material is detected based on the roll material detection range and the set deviation correction sensor, a detection result is determined based on the shielding range of the roll material in the detection field of view of the deviation correction sensor, and a real-time roll material width value of the roll material is generated based on the detection result.

[0072] In a possible implementation, after the roll material middle range is determined in the foregoing process, the roll material is detected in real time based on the roll material middle range and the deviation correction sensor, and a real-time roll material width value of the roll material is determined, so as to facilitate subsequent judgment of whether the roll material deviates based on the roll material width value. The specific implementation is as follows:

[0073] The deviation correction detection is performed on the roll material based on the roll material detection range, and a real-time roll material width value of the roll material is generated based on a detection result, and the method comprises the following steps of:

[0074] The roll material is detected based on the deviation correction sensor and the roll material detection range, a real-time shielding range of the roll material in the detection range corresponding to the deviation correction sensor is determined, and the method comprises the following steps of:

[0075] A real-time roll material width value of the roll material is generated based on the real-time shielding range and the roll material middle range.

[0076] Specifically, the roll material is detected based on the deviation correction sensor located on both sides of the roll material and the roll material detection range set by the deviation correction sensor, a real-time shielding range of the roll material in the detection range corresponding to the deviation correction sensor is determined, and a real-time roll material width value of the roll material is generated based on the real-time shielding range and the roll material middle range calculated in the foregoing process.

[0077] For example, it is determined that the shielding range of the roll material is 20 through the deviation correction sensor located on both sides of the roll material, and a real-time roll material width value of the roll material is determined to be 100 based on the roll material middle range 60.

[0078] Step 103: It is judged whether the roll material deviates based on the real-time roll material width value and the width information, and the deviation correction controller is controlled to perform centering deviation correction in a case where it is determined that the roll material deviates.

[0079] Specifically, it is judged whether the roll material deviates based on the real-time roll material width value calculated in the foregoing process and the width information of the roll material, and the deviation correction sensor is controlled to perform centering deviation correction in a case where it is determined that the roll material deviates.

[0080] In a possible implementation, when judging whether the to-be-tested web material is deviated, the real-time web material width value can be scaled proportionally, so as to reduce the calculation amount of data and improve the efficiency of generating the calculation result, and the specific implementation method is as follows:

[0081] The method further includes:

[0082] scaling the real-time web material width value proportionally to generate a target real-time web material width value;

[0083] judging whether the target real-time web material width value is equal to the width information.

[0084] For example, when it is determined by calculation that the real-time web material width value of the to-be-tested web material is 11000, the real-time web material width value is scaled proportionally to obtain a target real-time web material width value 110, and then the target real-time web material width value is compared with the width information of the to-be-tested web material to judge whether the to-be-tested web material is deviated.

[0085] In a possible implementation, after the target real-time web material width value is calculated, the target real-time web material width value is compared with the width information of the to-be-tested web material, so as to further judge whether the to-be-tested web material is deviated by preparing to identify the width information of the to-be-tested web material, and the specific implementation method is as follows:

[0086] The method further includes:

[0087] In a case where the target real-time web material width value is greater than or less than the width information, the deviation controller is controlled to perform the centering deviation correction based on the real-time web material width value.

[0088] In a possible embodiment, as described in the foregoing embodiments, in a case where the target real-time web material width value of the to-be-tested web material is 110, it is judged that the target real-time web material width value is greater than the width information 100 of the to-be-tested web material, and the deviation controller is controlled to perform the centering deviation correction.

[0089] In addition, after the real-time web material width value is generated, not only can the judgment of whether the to-be-tested web material is deviated be automatically performed based on the width information, but also the real-time web material width value and other information can be transmitted to a target object, and the target object judges whether the centering deviation correction is needed based on the real-time web material width value and performs the specific implementation of the centering deviation correction, and the specific implementation method is as follows:

[0090] The method further includes:

[0091] feedback the real-time coil width value and the width information to a target object, and display the real-time coil width value and the width information.

[0092] The target object can be a PLC terminal device (i.e., Programmable Logic Controller) or other terminal device capable of displaying data.

[0093] Specifically, after calculating the real-time coil width value, the real-time coil width value and the width information of the coil to be measured are fed back to the target object, and the real-time coil width value and the width information are displayed, so as to facilitate data viewing and analysis by relevant personnel.

[0094] Furthermore, after feeding back the real-time coil width value and the width information to the target object, corresponding centering and correction operations can be performed based on the instructions fed back by the target object, and the specific implementation mode is as follows:

[0095] The method further comprises the following steps:

[0096] In response to the centering and correction instructions of the target object for the real-time coil width value and the width information, the centering and correction controller is controlled to perform centering and correction.

[0097] Specifically, after receiving the real-time coil width value and the width information, the target object can view and analyze the real-time coil width value and the width information, and generate centering and correction instructions based on the above data. The centering and correction instructions carry corresponding centering and correction execution information, and the centering and correction controller is controlled to perform centering and correction based on the centering and correction instructions.

[0098] The width measurement and correction method provided by one embodiment of the present specification sets at least one correction sensor on the first side of the coil to be measured, sets at least one correction sensor on the second side of the coil to be measured, and sets a correction controller corresponding to the correction sensor. The coil detection range of the correction sensor is set based on the width information of the coil to be measured, wherein the coil detection range is the shielding range of the correction sensor for the coil to be measured. The coil to be measured is detected based on the coil detection range, and a real-time coil width value of the coil to be measured is generated based on the detection result. Whether the coil to be measured has deviated is determined based on the real-time coil width value and the width information, and the correction controller is controlled to perform centering and correction in the case where it is determined that the coil to be measured has deviated, thereby realizing accurate detection of the coil to be measured under different field widths.

[0099] Corresponding to the method embodiments described above, the present specification also provides a width measurement and deviation correction device embodiment, Figure 3 A structural diagram of a width measurement and deviation correction device is shown according to an embodiment of the present specification.
