However, persons skilled in the art will understand that the present application can be practiced without these specific details.

[0031] In the description of the present application and the appended claims, the terms "first", "second", "third", etc. are used only to distinguish descriptions, and cannot be understood as indicating or implying relative importance.

[0032] In the present application, the reference "one embodiment" or "some embodiments" means that the specific features, structures or characteristics described in connection with the embodiment are included in one or more embodiments of the present application. Therefore, the statements "in one embodiment", "in some embodiments", "in other some embodiments", "in further some embodiments" and the like appearing in different places in the present specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized. The terms "include", "contain", "have" and their variants mean "include but not limited to", unless otherwise specifically emphasized.

[0033] In order to illustrate the technical solutions described in the present application, specific embodiments are described below.

[0034] Please refer to Figure 1 , Figure 1 is a flowchart of a real-time control method based on a continuous roll-to-roll carbon paper production line provided in an embodiment of the present application. In this embodiment, the execution subject of the real-time control method is a terminal device. It can be understood that the types of the terminal device include but are not limited to a mobile phone, a tablet computer, a notebook computer, an Ultra-Mobile Personal Computer (UMPC), a netbook, a Personal Digital Assistant (PDA), etc., and the specific type of the terminal device is not limited in the embodiments of the present application.

[0035] Please refer to Figure 1 The real-time control method provided in the embodiments of the present application includes but is not limited to the following steps:

[0036] In S100, the protruding peak information of the target workpiece at the discharge place of the extrusion device is acquired.

[0037] Specifically, the real-time control method can be applied to a carbon paper production line, wherein the carbon paper production line includes a roll-off device, a dipping device, an extrusion device and a roll-up device sequentially connected from the first end to the last end. The roll-off device is used to roll out the carbon paper, the dipping device is used to dip the carbon paper, the extrusion device is used to extrude the carbon paper, and the roll-up device is used to roll up the processed carbon paper. The carbon paper is first rolled out by the roll-off device, then enters the dipping device from the inlet of the dipping device, then leaves the dipping device from the outlet of the dipping device, then enters the extrusion device from the inlet of the extrusion device, then leaves the extrusion device from the outlet of the extrusion device, and then is rolled up by the roll-up device.

[0038] Without loss of generality, the carbon paper is composed of many carbon fiber tows, and there may be accumulation at the positions where different carbon fiber tows interweave. Since the gap between the accumulated carbon fiber tows is small and the density is high, the dipping liquid of the dipping device needs a certain time to penetrate into the carbon fiber tows. When the dipping liquid of the dipping device does not fully penetrate into each carbon fiber of the carbon paper, for example, does not penetrate into the accumulated carbon fiber tows, the dipping liquid cannot firmly bond the accumulated position and the surrounding carbon fiber tows together, resulting in that the carbon fiber tows at the accumulated position are separated from the surrounding carbon fiber tows during the extrusion processing of the extrusion device, forming protrusions and unable to form a relatively flat surface.

[0039] Specifically, in order to facilitate subsequent determination of a sizing time that can meet the requirement of the sizing liquid to fully penetrate into each carbon fiber of the carbon paper and maximize the production efficiency, the operator can first preset the sizing time as a shorter time value, which is less than the current conventional conservative sizing time, for example, the preset sizing time can be half or one third of the current conventional conservative sizing time, thereby achieving the reduction of the total production time and the improvement of the production efficiency.

[0040] Specifically, the terminal device can obtain protrusion peak information corresponding to the target workpiece at the discharge of the extrusion device, wherein the protrusion peak information is used to describe the height of the highest protrusion of the target workpiece, and the target workpiece is carbon paper, which can be named carbon fiber paper, carbon cloth or carbon fiber cloth.

[0041] In some possible implementation manners, in order to facilitate accurate determination of the protrusion, please refer to Figure 2 , step S100 includes but is not limited to the following steps:

[0042] In S110, based on the industrial camera, high-precision image information of the target workpiece is obtained.

[0043] Without loss of generality, the target workpiece is in a horizontal state and leaves the extrusion device from the discharge of the extrusion device, and the carbon paper production line can be pre-installed with an industrial camera, which is located at the discharge of the extrusion device in the carbon paper production line, and the industrial camera and the target workpiece are located on the same horizontal plane, the photographing axis of the industrial camera is perpendicular to the direction of movement of the target workpiece, and the photographing axis is the direction of the central axis of the lens of the industrial camera.

[0044] Specifically, the terminal device can first obtain high-precision image information of the target workpiece based on the industrial camera, and the high-precision image information is used to describe the image obtained by the industrial camera when the target workpiece at the discharge of the extrusion device is photographed.

[0045] In S120, based on the preset contour extraction algorithm, top surface contour line information and bottom surface contour line information of the target workpiece are determined.

[0046] Without loss of generality, the preset contour extraction algorithm can be an edge detection algorithm based on a Sobel operator, an edge detection algorithm based on a Laplacian operator or an edge detection algorithm based on a Hough transform.

[0047] Specifically, the terminal device can determine the top surface profile line information and the bottom surface profile line information of the target workpiece based on a preset profile extraction algorithm, wherein the top surface profile line information is used to describe the profile line of the top surface of the target workpiece, the top surface is the upper surface, the top surface profile line information includes a plurality of top surface profile point information, the top surface profile line information is composed of the plurality of top surface profile point information, the bottom surface profile line information is used to describe the profile line of the bottom surface of the target workpiece, the bottom surface is the lower surface, the bottom surface profile line information includes a plurality of bottom surface profile point information, and the bottom surface profile line information is composed of the plurality of bottom surface profile point information. For example, refer to the dots marked as "A1", the dots marked as "B1" and the dots marked as "C1" in Figure 3 , Figure 3 , the dots marked as "A1", the dots marked as "B1" and the dots marked as "C1" in Figure 3 , the dots marked as "A2", the dots marked as "B2" and the dots marked as "C2" in

[0048] In S130, the profile line distance set information is generated according to the top surface profile line information and the bottom surface profile line information.

[0049] Without loss of generality, the profile line distance set information includes a plurality of profile line distance information, and the profile line distance information is used to describe the distance between the top surface profile point information and the bottom surface profile point information located on the same vertical plane. For example, refer to the distances corresponding to D1, the distances corresponding to D2 and the distances corresponding to D3 in Figure 3 , Figure 3 , the distances corresponding to D1, the distances corresponding to D2 and the distances corresponding to D3 in

[0050] Specifically, the terminal device can determine the distance between each pair of top surface profile point information and bottom surface profile point information located on the same vertical plane according to the top surface profile line information and the bottom surface profile line information, and generate the profile line distance set information. For example, the terminal device can first determine a group of profile points of the top surface profile point information and the bottom surface profile point information located on the same vertical plane, and then perform the following processing on each group of profile points: determining the Euclidean distance between the top surface profile point information and the bottom surface profile point information according to a preset Euclidean distance calculation formula, the Euclidean distance being the profile line distance information, and generating the profile line distance set information according to all the profile line distance information after the terminal device determines the profile line distance information corresponding to each group of profile points.

[0051] In S140, the maximum distance information is determined based on the profile line distance set information.

[0052] Specifically, the maximum distance information is used to describe the maximum profile line distance information in the profile line distance set information, and the terminal device can determine the maximum distance information based on the plurality of profile line distance information in the profile line distance set information. For example, refer to the distances corresponding to D1, the distances corresponding to D2 and the distances corresponding to D3 in Figure 3, Figure 3 The profile line spacing information corresponding to the middle D3 is maximum spacing information.

[0053] In S150, the maximum spacing information is determined as the convex peak value information.

[0054] Specifically, after the terminal device determines the maximum spacing information, the terminal device can determine the maximum spacing information as the convex peak value information.

[0055] In S200, the convex peak value information is compared with preset convex limit value information.

[0056] Specifically, the terminal device can compare the convex peak value information with the preset convex limit value information, the convex limit value information is used as a limit value for judging whether the target workpiece has a convex that does not meet the production requirements, the convex limit value information can be preset by an operator, and the convex peak value information greater than the convex limit value information indicates that the target workpiece has a convex that does not meet the production requirements, and the convex peak value information less than or equal to the convex limit value information indicates that the target workpiece does not have a convex that does not meet the production requirements.

[0057] In S300, if the convex peak value information is greater than the convex limit value information, the unwinding device is controlled according to a first deceleration instruction, and the winding device is controlled according to a second deceleration instruction.

[0058] Specifically, the first deceleration instruction is used to instruct the unwinding device to slow down the unwinding speed to a first target speed value, and the second deceleration instruction is used to instruct the winding device to slow down the winding speed to a second target speed value. If the convex peak value information is greater than the convex limit value information, the terminal device can control the unwinding device according to the first deceleration instruction, and control the winding device according to the second deceleration instruction.

[0059] In some possible implementations, in order to enable the impregnating solution to have sufficient time to penetrate into each carbon fiber of the carbon paper and improve production efficiency, please refer to Figure 4 , the step S300 includes but is not limited to the following steps:

[0060] In S310, if the convex peak value information is greater than the convex limit value information, first real-time unwinding speed information of the unwinding device is obtained, and first real-time winding speed information of the winding device is obtained.

[0061] Specifically, if the convex peak value information is greater than the convex limit value information, the terminal device can obtain the first real-time unwinding speed information of the unwinding device, and simultaneously obtain the first real-time winding speed information of the winding device, wherein the first real-time unwinding speed information is used to describe the real-time unwinding speed of the unwinding device, and the first real-time winding speed information is used to describe the real-time winding speed of the winding device.

[0062] In S320, a first target speed value is determined according to the first real-time unwinding speed information and preset deceleration constant information, and a second target speed value is determined according to the first real-time winding speed information and the deceleration constant information.

[0063] Specifically, the deceleration constant information is a fixed value, the first target speed value is used to describe a difference between the first real-time unwinding speed information and the deceleration constant information, and the second target speed value is used to describe a difference between the first real-time winding speed information and the deceleration constant information. The terminal device can determine the first target speed value according to the first real-time unwinding speed information and the preset deceleration constant information, and determine the second target speed value according to the first real-time winding speed information and the deceleration constant information. For example, when the first real-time unwinding speed information is 50 cm per minute and the deceleration constant information is 5 cm per minute, the first target speed value is 45 cm per minute.

[0064] In S330, a first deceleration instruction is generated based on the first target speed value, and a second deceleration instruction is generated based on the second target speed value.

[0065] Specifically, the terminal device can generate the first deceleration instruction based on the first target speed value, and generate the second deceleration instruction based on the second target speed value.

[0066] In S340, the unwinding device is controlled according to the first deceleration instruction, and the winding device is controlled according to the second deceleration instruction.

[0067] Specifically, after the terminal device generates the first deceleration instruction, the terminal device can control the unwinding device according to the first deceleration instruction, and after the terminal device generates the second deceleration instruction, the terminal device can control the winding device according to the second deceleration instruction.

[0068] In S400, the following steps are repeatedly performed: obtaining protruding peak information of the target workpiece at the discharge of the extrusion device, comparing the protruding peak information with preset protruding limit value information, if the protruding peak information is greater than the protruding limit value information, generating a first deceleration instruction and a second deceleration instruction, and if the protruding peak information is greater than the protruding limit value information, controlling the unwinding device according to the first deceleration instruction and controlling the winding device according to the second deceleration instruction, until the protruding peak information is less than or equal to the protruding limit value information.

[0069] Specifically, the terminal device can cyclically execute the step S100, the step S200 and the step S300 until the convex peak value information is less than or equal to the convex limit value information, thereby prolonging the time of the target workpiece in the impregnating solution and enabling the impregnating solution to fully penetrate into each carbon fiber of the carbon paper. Since the initially preset impregnating time is already significantly shorter than the currently conventional conservative impregnating time, the total production time can still be significantly shorter than the total production time of the current conventional process, thereby improving the production efficiency.

[0070] In S500, the unwinding device is controlled according to the preset first constant-speed instruction, and the winding device is controlled according to the preset second constant-speed instruction.

[0071] Specifically, the first constant-speed instruction is used to instruct the unwinding device to maintain the unwinding speed at the first target speed value, and the second constant-speed instruction is used to instruct the winding device to maintain the winding speed at the second target speed value; the terminal device can control the unwinding device according to the preset first constant-speed instruction and control the winding device according to the preset second constant-speed instruction.

[0072] In some possible implementations, in order to facilitate other continuous roll-to-roll carbon paper production lines to refer to the production parameters of the continuous roll-to-roll carbon paper production line, reduce the link of initially determining the impregnating time that can both enable the impregnating solution to fully penetrate into the carbon paper and improve the production efficiency, and enable the other continuous roll-to-roll carbon paper production lines to directly start production at a higher production efficiency, please refer to Figure 5 After the step S500, the method further includes but is not limited to the following steps:

[0073] In S600, the second real-time unwinding speed information of the unwinding device is acquired, and the second real-time winding speed information of the winding device is acquired.

[0074] Specifically, the second real-time unwinding speed information is used to describe the real-time unwinding speed of the unwinding device after the terminal device controls the unwinding device according to the first constant-speed instruction, and the second real-time winding speed information is used to describe the real-time winding speed of the winding device after the terminal device controls the winding device according to the second constant-speed instruction. The terminal device can acquire the second real-time unwinding speed information of the unwinding device and the second real-time winding speed information of the winding device.

[0075] In S610, the first production reference data packet information is generated according to the second real-time unwinding speed information and the second real-time winding speed information.

[0076] Specifically, the terminal device can generate the first production reference data packet information according to the second real-time unwinding speed information and the second real-time winding speed information.

[0077] In some possible implementations, to further facilitate other carbon paper production lines to directly start production at a higher production efficiency, please refer to Figure 6 After step S610, the method further includes but is not limited to the following steps:

[0078] In S620, the use duration information and the proportion information of the sizing liquid of the sizing equipment are acquired.

[0085] Specifically, the terminal device can generate the second production reference data packet information according to the second real-time unwinding speed information, the second real-time winding speed information, the use duration information of the sizing liquid, the proportion information of the sizing liquid, the viscosity information of the sizing liquid, and the temperature information of the sizing liquid.
