Description

Technical Field

[0001] The present invention relates to the technical field of electrostatic spinning, and in particular to an electrostatic spinning production environment monitoring and early warning system and method. Background Art

[0002] The basic principle of the electrospinning process is to generate charges by applying high voltage to generate mutually repulsive forces to overcome the surface tension in the charged polymer liquid, and the thinning effect of the charged jet is mainly completed by the bending instability associated with the electrospinning jet. The voltage is applied between the spinneret and the collector, and the surface charge accumulates on the surface of the solution. When the electric field exceeds a certain value, the electrostatic repulsion of the surface charge overcomes the surface tension, and the charged fluid jet is ejected from the tip of the Taylor cone and forms fibers on the collecting substrate in the electrospinning device. In the electrospinning process, many factors including solution properties (such as viscosity, concentration, conductivity, etc.), processing conditions (such as voltage, flow rate, collection distance, etc.) and environmental conditions (temperature, humidity, atmosphere, pressure, etc.) have different effects on the diameter, organization / arrangement, surface morphology and wettability of the final product. By adjusting the electrospinning parameters, the desired nanofiber characteristics can be achieved.

[0003] At present, relevant research has proposed a technical solution to achieve the required spinning requirements by monitoring the electrospinning process to adaptively adjust the electrospinning parameters. For example, the patent document with publication number CN105442067A proposes a temperature and humidity automatically controlled electrospinning device chassis, including a box with a sliding door; a lighting device and an environmental control device are arranged in the box; the lighting device includes a lighting lamp installed inside the box and a switch installed inside the sliding door; and a running wheel is arranged at the bottom of the box. The sliding door includes a first door panel and a second door panel; two slideways are arranged in parallel on the front of the box, and the first door panel and the second door panel are respectively installed on one of the slideways. The left and right sides of the first door panel and the left and right sides of the second door panel are provided with inward buckle handles. In this technical solution, the temperature and humidity sensor will monitor the temperature and humidity in the box in real time, and the temperature and humidity of the box are automatically controlled to be suitable for spinning operations, with a high degree of automation. The exhaust module arranged on the box can ensure good ventilation in the box, and the exhaust process filters out impurities through the filter element, does not pollute the environment, and can avoid dust intrusion.

[0004] The above technical solution continuously monitors the spinning environment according to the established temperature and humidity parameters. However, intermittent small fluctuations in the spinning environment parameters will be ignored. The accumulation of such errors between the environmental parameters may cause quality impacts on the spinning process that cannot be determined by the electrospinning control system.

[0005] In addition, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making the present invention, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the present invention does not have the characteristics of these prior arts. On the contrary, the present invention already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology. Summary of the invention

[0006] In view of the deficiencies of the prior art, the present invention provides a production environment monitoring and early warning system and method for electrospinning. The system includes: a direct control module, which is used to regulate the environmental parameters of the production environment during the electrospinning process through at least one sub-control unit. The system includes: a monitoring module, which is used to monitor the environmental parameters of the production environment. The monitoring module is configured to: determine the imbalance time period information of at least one sub-control unit about at least one specified environmental parameter change information within the active monitoring duration. The monitoring module determines the spinning environment risk early warning coefficient of the direct control module in the real-time early warning coefficient evaluation stage based on at least the imbalance time period information of at least one specified environmental parameter change information obtained from at least one sub-control unit within the active monitoring duration.

[0007] The sub-control unit mentioned in the present application includes at least one of a temperature control system, a voltage control system, a humidity control system, a liquid supply control system, an air supply device, and a collection end control device. The direct control module coordinately controls the working parameters of all sub-control units to regulate the spinning production environment.

[0008] The active monitoring duration mentioned in this application may refer to a preset monitoring period, and the imbalance time period information is periodically collected. The specified environmental parameter change information may refer to a preset threshold value / threshold range of environmental parameters such as temperature and electric field strength. The imbalance time period information may refer to the degree and time of the detected real-time working data / environmental data deviation from the specified environmental parameter change information. Since the deviation of the working data / environmental data may be instantaneous, or continuous for a period of time, or intermittent multiple deviations, the imbalance time period information may include one or several time period information. The real-time early warning coefficient evaluation stage may refer to the early warning coefficient evaluation stage corresponding to the current moment.

[0009] In this application, the monitoring module acquires the environmental parameters of the production environment in real time, and performs real-time monitoring based on the monitoring conditions with higher trigger thresholds, and the monitoring module periodically conducts a comprehensive evaluation of the environmental parameters of the production environment over a period of time based on the active monitoring duration. This not only achieves the goal of real-time monitoring, but also periodically conducts a comprehensive evaluation of smaller parameter fluctuations that do not trigger real-time monitoring conditions, so as to adjust the spinning environment parameters in a timely manner and avoid sudden production environment fluctuations caused by the accumulation of errors.

[0010] Preferably, the monitoring module is also configured to enter the real-time early warning coefficient evaluation stage when it is determined that the current moment triggers the active monitoring stage related to the preset environmental parameters, and send the corresponding designated environmental parameter change information to at least one of its sub-control units according to the early warning coefficient of the direct control module in the previous early warning coefficient evaluation stage during the active monitoring duration. The designated environmental parameter change information in the current real-time early warning coefficient evaluation stage is determined based on the early warning coefficient of the previous early warning coefficient evaluation stage. The monitoring module is preset with basic designated environmental parameter change information. Each real-time early warning coefficient evaluation stage corresponds to the designated environmental parameter change information obtained by multiplying the basic designated environmental parameter change information with the proportion corresponding to the early warning coefficient of the previous early warning coefficient evaluation stage. When the early warning coefficient of the previous stage is high, the corresponding proportion value is relatively small, which makes the designated environmental parameter for monitoring in the current stage relatively smaller, thereby improving the monitoring level of the monitoring module in the current stage.

[0011] Preferably, the system further comprises an electrospinning device and a collecting end regulating device. The electrospinning device is used to make the spinning liquid detach from at least one of its sub-spinning parts in the form of a tiny jet under an electric field provided between the electrospinning device and the collecting end regulating device and be captured by the collecting end regulating device to form a spinning layer. If the imbalance time period information obtained in the real-time warning coefficient evaluation stage is within the range specified by the first specified environmental parameter change information and the second specified environmental parameter information, the monitoring module retrieves the detection information about the spinning layer within the active monitoring time and judges it based on the preset spinning layer conditions. The monitoring module determines that at least one sub-control unit corresponds to the first warning coefficient in the real-time warning coefficient evaluation stage in combination with the judgment result, and at least one sub-control unit instructs the monitoring module to send warning information to the mobile terminal operated by the production personnel according to the first warning coefficient. The specified environmental parameter change information can be an index value range, including the endpoint value of the first and second specified environmental parameter information.

[0012] When the unbalanced time period information is between the range specified by the first specified environmental parameter change information and the second specified environmental parameter information, the monitoring module obtains the detection information about the spinning layer, and further determines whether the unbalanced time period information affects the formation of the spinning layer. According to the influence of the unbalanced time period information on the formation of the spinning layer, the first warning coefficient can be determined accordingly. The warning coefficient can include preset levels such as level one, level two, level three, etc., and the warning information is issued to the production personnel accordingly, and the production personnel can determine the degree of risk.

[0013] When the imbalance time period information exceeds the range specified by the first specified environmental parameter change information and the second specified environmental parameter information, the monitoring module outputs a second warning coefficient corresponding to the imbalance time period information and sends a warning message to a mobile terminal operated by a production staff.

[0014] Preferably, the collecting end adjustment device at least includes a light control component, a first image acquisition component and a first data processing module, and the detection information about the spinning layer includes the first information and the second information respectively acquired by the light control component and the first image acquisition component. Wherein, in the case where the spinning solution contains photosensitive components, the spinning solution can be separated from at least one sub-spinning element under the electric field in the form of a tiny jet that carries photosensitive particles and at least overcomes the surface tension formed between the spinning solutions and is captured by the collecting end adjustment device to form a spinning layer, the light control component is configured to project regional light to the spinning layer captured by the collecting end adjustment device and leaving the electric field area with its collecting substrate, and the first image acquisition component performs image acquisition on the spinning layer.

[0015] Preferably, the collecting end regulating device comprises at least a first data processing module, and the first data processing module obtains spinning state information about at least one sub-spinning element based on at least detection information about the spinning layer.

[0016] Preferably, the light control component is configured to intermittently project regional light onto the spinning layer which is captured by the collecting end adjustment device and leaves the electric field area with the collecting substrate, so as to obtain regional density distribution information about the spinning layer based on the regional light and trigger the first image acquisition component to capture images of the spinning layer and identify and obtain local fiber distribution information about the spinning layer.

[0017] Preferably, the first data processing module has a first preset spinning condition regarding the density distribution of the spinning layer. When it is monitored that the regional density distribution information generated by the light control component triggers the first preset spinning condition, the first data processing module determines at least one sub-spinning component in the electrospinning device corresponding to the trigger in combination with the local fiber distribution information.

The system at least includes: a monitoring module, which is used to monitor the environmental parameters of the production environment. The monitoring module retrieves the detection information about the spinning layer within the active monitoring period and judges it based on the preset spinning layer conditions. The monitoring module determines that at least one sub-control unit corresponds to the first warning coefficient in the real-time warning coefficient evaluation stage in combination with the judgment result. At least one sub-control unit instructs the monitoring module to send warning information to a mobile terminal operated by a production personnel according to the first warning coefficient.

DETAILED DESCRIPTION

[0026] The present application is described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] This embodiment proposes an electrospinning control system. Without causing conflict or contradiction, the whole and / or part of the preferred implementation methods of other embodiments can be used as a supplement to this embodiment.

[0029] The system comprises a direct control module 1. The direct control module 1 is used to adjust environmental parameters of the production environment during the electrospinning process through at least one sub-control unit 2.

[0030] The system includes a monitoring module 3. The monitoring module 3 is used to monitor the environmental parameters of the production environment. The monitoring module 3 can determine the imbalance time period information of at least one sub-control unit 2 about at least one specified environmental parameter change information within the active monitoring duration. The monitoring module 3 determines the spinning environment risk warning coefficient of the direct control module 1 in the real-time warning coefficient evaluation stage based on at least the imbalance time period information of at least one specified environmental parameter change information of at least one sub-control unit 2 obtained within the active monitoring duration.

[0031] The sub-control unit 2 mentioned in the present application includes at least one of a temperature control system 4, a voltage control system 5, a humidity adjustment system 6, a liquid supply adjustment system 7, an air supply device 8, and a collection end adjustment device 9. The direct control module 1 coordinately controls the working parameters of all sub-control units 2 to regulate the spinning production environment.

[0032] The active monitoring duration mentioned in this application may refer to a preset monitoring period, and the imbalance time period information is periodically collected. The specified environmental parameter change information may refer to a preset threshold value / threshold range of environmental parameters such as temperature and electric field strength. The imbalance time period information may refer to the degree and time of the detected real-time working data / environmental data deviation from the specified environmental parameter change information. Since the deviation of the working data / environmental data may be instantaneous, or continuous for a period of time, or intermittent multiple deviations, the imbalance time period information may include one or several time period information. The real-time early warning coefficient evaluation stage may refer to the early warning coefficient evaluation stage corresponding to the current moment.

[0033] In this application, the monitoring module 3 acquires the environmental parameters of the production environment in real time, and performs real-time monitoring according to the monitoring conditions with higher trigger thresholds, and the monitoring module 3 periodically conducts a comprehensive evaluation of the environmental parameters of the production environment within a period of time based on the active monitoring duration. This not only achieves the goal of real-time monitoring, but also periodically conducts a comprehensive evaluation of smaller parameter fluctuations that do not trigger real-time monitoring conditions, so as to adjust the spinning environment parameters in a timely manner and avoid sudden production environment fluctuations caused by the accumulation of errors.

[0034] Preferably, the monitoring module 3 is also configured to enter the real-time warning coefficient evaluation stage when it is determined that the active monitoring stage related to the preset environmental parameters is triggered at the current moment, and send the corresponding designated environmental parameter change information to at least one of its sub-control units 2 according to the warning coefficient of the direct control module 1 in the previous warning coefficient evaluation stage during the active monitoring duration. The designated environmental parameter change information in the current real-time warning coefficient evaluation stage is determined based on the warning coefficient of the previous warning coefficient evaluation stage. The monitoring module 3 is preset with basic designated environmental parameter change information. Each real-time warning coefficient evaluation stage corresponds to the designated environmental parameter change information obtained by multiplying the basic designated environmental parameter change information with the proportion corresponding to the warning coefficient of the previous warning coefficient evaluation stage. When the warning coefficient of the previous stage is high, the corresponding proportion value is relatively small, which makes the designated environmental parameter for monitoring in the current stage relatively smaller, thereby improving the monitoring level of the monitoring module 3 in the current stage.

[0035] Preferably, the system further comprises an electrospinning device 12 and a collecting end regulating device 9. The electrospinning device 12 is used to make the spinning solution detach from at least one of its sub-spinning parts in the form of a tiny jet under the electric field provided between the electrospinning device 12 and the collecting end regulating device 9 and be captured by the collecting end regulating device 9 to form a spinning layer 13. If the imbalance time period information obtained in the real-time warning coefficient evaluation stage is within the range specified by the first specified environmental parameter change information and the second specified environmental parameter information, the monitoring module 3 retrieves the detection information about the spinning layer 13 within the active monitoring time and judges it based on the preset spinning layer 13 conditions. The monitoring module 3 determines that at least one sub-control unit 2 corresponds to the first warning coefficient in the real-time warning coefficient evaluation stage in combination with the judgment result, and at least one sub-control unit 2 instructs the monitoring module 3 to send warning information to the mobile terminal operated by the production personnel according to the first warning coefficient. The specified environmental parameter change information can be an index value range, including the endpoint value of the first and second specified environmental parameter information.

[0036] When the unbalanced time period information is between the range specified by the first specified environmental parameter change information and the second specified environmental parameter information, the monitoring module 3 obtains the detection information about the spinning layer 13, and further determines whether the unbalanced time period information affects the formation of the spinning layer 13. According to the influence of the unbalanced time period information on the formation of the spinning layer 13, the first warning coefficient can be determined accordingly. The warning coefficient can include preset levels such as level one, level two, level three, etc., and the warning information is issued to the production personnel accordingly, and the production personnel can determine the risk level.

[0037] When the imbalance time period information exceeds the range specified by the first specified environmental parameter change information and the second specified environmental parameter information, the monitoring module 3 outputs a second warning coefficient corresponding to the imbalance time period information and sends a warning message to a mobile terminal operated by a production staff.

[0038] The sub-control unit 2 mentioned in the present application includes at least one of a temperature control system 4, a voltage control system 5, a humidity adjustment system 6, a liquid supply adjustment system 7, an air supply device 8, and a collection end adjustment device 9. The direct control module 1 coordinately controls the working data / environmental data of all sub-control units 2 to regulate the spinning production environment.

[0039] In the present application, the temperature control system 4 can adjust the preset temperature according to the different temperature requirements of different polymer solutions. When the temperature of some components of the equipment is higher than the preset temperature, the temperature control system 4 generates an early warning message and feeds back to the direct control module 1 or the main control panel. In the present application, the voltage control system 5 can adjust the initial voltage according to the spinning requirements, and the voltage adjustment range is 5-50kv. When the voltage is unstable or there is an error between the actual voltage and the set voltage during the operation of the electrospinning equipment, an early warning message is generated and fed back to the direct control module 1 or the main control panel.

[0040] In the present application, the humidity adjustment system 6 is used to obtain the current production environment humidity. The humidity adjustment system 6 can determine the target production environment humidity according to the humidity adjustment instruction. The humidity adjustment system 6 can adjust the current production environment humidity to the target production environment humidity.

[0041] In the present application, in the liquid holding device for holding the polymer solution, the liquid supply regulating system 7 can stop adding liquid when it detects that the polymer solution has reached the maximum liquid holding range. If the polymer solution reaches the minimum liquid holding range, it will affect the spinning efficiency / effect. The liquid supply regulating system 7 can generate an early warning message when the polymer solution reaches the minimum liquid holding range and feed it back to the direct control module 1 / main control panel. The liquid supply regulating system 7 can adjust the volume of the polymer solution in the liquid holding device according to actual needs.

[0042] In the present application, the air supply device 8 is used to spray air in the spinning direction, that is, in the direction of the substrate, and the flow rate and temperature of the sprayed air can be adjusted. High temperature accelerates the solidification of the electrospun fiber, and low temperature reduces the temperature of the spinning equipment.

[0043] In the present application, the collecting end regulating device 9 can be used to control the conveying speed of the collecting end substrate. When the collecting end regulating device 9 detects that the substrate is pulled or torn on the conveying device, it generates an early warning message and feeds it back to the direct control module 1 or the main control panel, and stops the conveying of the substrate.

[0044] In the present application, the monitoring system further includes a smoke sensor. The smoke sensor is used to detect smoke in the production environment where the production system is located. When the smoke concentration exceeds a preset concentration threshold, the smoke sensor generates a smoke warning message and sends it to the direct control module 1 or the main control panel.

[0045] Example 2

[0046] This embodiment may be a further improvement and / or supplement to Embodiment 1, and repeated contents will not be repeated. In the case of no conflict or contradiction, the whole and / or part of the preferred implementation modes of other embodiments may be used as a supplement to this embodiment.

[0047] This embodiment proposes a collecting end regulating device 9. The collecting end regulating device 9 includes a collecting substrate. The collecting substrate continuously passes through both ends of the electrospinning device 12 in the first direction. Both ends of the collecting substrate are respectively rolled up. When spinning, the two ends of the rolls are rotated respectively, so that the collecting substrate gradually passes through the electrospinning device 12, and the micro jet formed in the electrospinning device 12 is collected on the collecting substrate and then taken away from the electrospinning device 12.

[0048] The collecting end adjustment device 9 includes a light control component 14 for projecting regional light.

[0049] This embodiment also proposes a light control component 14. The light control component 14 includes at least a light emitter and a light detector. The light emitter and the light detector may be separately arranged or integrally arranged. Further preferably, the light emitter may be arranged on the same side of the spinning layer 13 as the light detector or respectively arranged on both sides of the spinning layer 13. In the case where the light emitter and the light detector are arranged on the same side of the spinning layer 13, the collecting substrate is a reflection layer with high reflectivity, and the light projected from the light emitter to the spinning layer 13 is reflected back by the collecting substrate and received and detected by the light detector. In the case where the light emitter and the light detector are arranged on both sides of the spinning layer 13, the collecting substrate is a projection layer with low reflectivity, and the light projected from the light emitter to the spinning layer 13 passes through the collecting substrate and is received and detected by the light detector.

[0050] This embodiment also proposes an electrospinning monitoring system, which includes at least a first image acquisition component 10. The collecting end adjustment device 9 includes the first image acquisition component 10. The first image acquisition component 10 is arranged on the same side of the collecting substrate as the side where the light emitter is located. The first image acquisition component 10 is arranged on the side where the spinning layer 13 is located on the collecting substrate. The first image acquisition component 10 may include a camera module and an image processing module.

[0051] The collecting end adjustment device 9 also includes a substrate conveyor. The substrate conveyor is a structure such as a conveying roller 6 arranged between the two ends of the collecting substrate. Specifically, the substrate conveyor can be two conveying rollers arranged side by side in a direction perpendicular to the collecting substrate (second direction). A conveying gap is arranged between the two conveying rollers for carrying the collecting substrate of the spinning layer 13 through. As the rollers in the substrate conveyor roll, the collecting substrate is conveyed so that the collecting substrate continuously captures the tiny jets formed by the spinning solution in the first direction. The width of the conveying gap in the second direction, i.e., the conveying gap, is adjustable. The conveying gap is adjusted by adjusting the distance between the two conveying rollers in the second direction. Preferably, the conveying gap is not greater than the sum of the thickness of the collecting substrate and the spinning layer 13 in the second direction, so that the thickness of the spinning layer 13 output through the substrate conveyor changes with the change of the conveying gap. The change refers to the compression of the spinning layer 13 in the thickness direction due to the pressure exerted by the substrate transmission device on the originally fluffy spinning layer 13 to meet the specified spinning layer thickness requirement or the specified spinning fiber pore requirement.

[0052] The first image acquisition component 10 and the light control component 14 are arranged at a position closer to the electric field region in the moving direction of the collection substrate relative to the substrate conveyor. That is, the collection substrate after the electrospinning is processed by the first image acquisition component 10 and the light control component 14 before entering the substrate conveyor for compression. The first image acquisition component 10 and the light control component 14 process the spinning layer 13 that has just finished the electrospinning and has not yet been subjected to the pressure of the substrate conveyor.

[0053] This embodiment also proposes an electrospinning monitoring system, which includes at least a second image acquisition component. Preferably, the electrospinning device 12 includes at least one second image acquisition component. The second image acquisition component can be arranged in the spinning area / electric field area. The second image acquisition component is used to perform image acquisition and identification on a plurality of sub-spinning parts. The second image acquisition component is not in the image acquisition state at all times, but is selectively entered into the image acquisition state by the regulation of the first data processing module 11. The second image acquisition component does not perform image acquisition on all sub-spinning parts at the same time, but is selectively performed image acquisition on a certain sub-spinning part by the regulation of the first data processing module 11. Preferably, the second image acquisition component can be provided with a protective cover and a purge mechanism. Under this setting, even if the second image acquisition component is arranged in the spinning area, due to the substantial reduction in the frequency of image acquisition, the second image acquisition component can be in the protective cover for most of the time. When image acquisition is required, the protective cover is opened for image acquisition and then closed, and the second image acquisition component is cleaned by the purge mechanism. While achieving effective image acquisition, the manual maintenance frequency required for the second image acquisition component is greatly reduced, and the execution efficiency is higher, reducing the power consumption of the overall device.

[0054] Preferably, the first image acquisition component 10 is configured to use the camera component to capture and identify the spinning layer 13 in a manner that the camera component maintains the same motion state as the acquisition target when capturing images. The camera component can be set on a track so that it can maintain the same motion state as the acquisition target in a manner that follows the moving speed and moving direction of the spinning layer 13. Usually, the winding speed of the spinning layer 13 is slow, and the stationary first image acquisition component 10 can smoothly capture the required image of the spinning layer 13. Under the above-mentioned tracking shooting setting, the image quality of the first image acquisition component 10 can be further effectively improved.

[0055] Preferably, the first image acquisition component 10 includes at least two parallel tracks. A camera component is respectively arranged on the two parallel tracks. The first image acquisition component 10 is configured to use at least two camera components to alternately acquire images and identify the spinning layer 13 in a manner of maintaining the same motion state as the acquisition target when acquiring images. Different from image acquisition in a static state, two camera components are required to alternately acquire images during follow-up shooting. During the current shooting cycle, one camera component moves along the track from the proximal end of the electrospinning device 12 to the distal end of the electrospinning device 12, and the other camera component moves along the track from the distal end of the electrospinning device 12 to the proximal end, for the next shooting cycle. Preferably, a mark for indicating the interval position of the shooting cycle is preset on the collection substrate. A visual mark is arranged at a certain distance on the collection substrate, which can be collected and identified by the image acquisition component. When the camera component located at the proximal end of the electrospinning device 12 acquires the mark, it moves in a motion state corresponding to the acquisition target and acquires image data at a preset time point. Preferably, the acquired image data contains the mark. Therefore, the images respectively acquired by the two camera components can be used to identify the specific areas of the spinning layer 13 to which they correspond respectively according to the preset identification order. At the same time, the local spinning layer 13 in the length direction that the first data processing module 11 needs to process within a period of time is relatively short, and the data processing volume is small, which can effectively ensure the data processing efficiency. In addition, the processed data can be stored in the storage module in a one-to-one correspondence with different identifications, which is conducive to tracing the spinning process when necessary. Even if the spinning efficiency of the electrospinning device 12 is further improved in subsequent research and the moving speed of the collecting substrate is increased, the above-mentioned monitoring system proposed in this embodiment can also be well applied.

[0056] The collecting end regulating device 9 includes a first data processing module 11. The first data processing module 11 can exchange information with other controllable devices in the electrospinning device 12. The controllable devices include a third data processing module included in the light control component 14. The light control component 14 mentioned in this embodiment is configured to execute a certain instruction or method step, which can also be understood as its third data processing module being configured to execute a certain instruction or method step.

[0057] The light control assembly 14 is configured to intermittently project regional light to the spinning layer 13 captured by the collecting end adjustment device 9 and leaving the electric field area with the collecting substrate. The intermittent projection of regional light mentioned here can refer to a projection method with a short projection time interval similar to continuous projection, a projection method with a long projection time interval similar to intermittent projection, or a combination projection method of alternating the above two methods.

[0058] The light control component 14 is configured to obtain regional density distribution information about the spinning layer 13 based on the regional light. The light receiver can detect the regional light after it passes through the spinning layer 13 and transmit the detection data to the third data processing module for processing and analysis.

[0059] After being triggered to capture images of the spinning layer 13 , the first image acquisition component 10 can perform data recognition based on the image acquisition and obtain local fiber distribution information about the spinning layer 13 .

[0060] In a preferred embodiment, the local fiber distribution information mentioned in this embodiment may refer to the distribution of nanofibers formed in / derived from different sub-spinning parts in the spinning layer 13 within the monitoring area of ​​the first image acquisition component 10.

[0061] The spinning solution provided to at least one of the sub-spinning elements of the electrospinning device 12 contains a photosensitive component. Under the irradiation of the regional light, the fibers of the photosensitive component in the spinning layer 13 absorb energy and develop color.

[0062] In this embodiment, under the electric field arranged between the electrospinning device 12 and the collecting end adjusting device 9, when the spinning liquid contains photosensitive components, the spinning liquid can be separated from at least one sub-spinning element in the form of a tiny jet carrying photosensitive particles and at least overcoming the surface tension formed between the spinning liquids, and be captured by the collecting end adjusting device 9 to form a spinning layer 13.

[0063] In this embodiment, when irradiated by regional light, the photosensitive particles in the local spinning on the spinning layer 13 corresponding to the regional light absorb the light energy so that the contrast between them and the collecting substrate on the collecting end adjustment device 9 meets the preset contrast threshold.

[0064] In this embodiment, the preset contrast threshold mainly refers to the color with a certain contrast with the collecting substrate formed due to the color development of the photosensitive particles of local spinning. This allows the image acquisition component to better capture the color development. The problem of increasing the difficulty of image data processing due to the similarity between the color of the collecting substrate and the color after development is avoided. In this embodiment, by adding a photosensitive component that changes color with light to the spinning solution, it is attached to the collecting substrate as the spinning solution forms a spinning jet, and the color development presented by the photosensitive particles after absorbing the light energy can form a certain contrast with the collecting substrate, so that the first image acquisition component 10 can be quickly identified. At the same time, since the light control component 14 projects regional light to the spinning layer 13, the light causes the photosensitive component to develop color on the one hand, and on the other hand, the irradiation of visible light enhances the ambient brightness required for image acquisition, which is conducive to more efficient image acquisition and recognition.

[0065] In this embodiment, at least two sub-spinning parts correspond to different photosensitive components. Under the irradiation of the regional light, the fibers with different photosensitive components in the spinning layer 13 are colored respectively. The electrospinning device 12 can provide spinning solutions with different components to the at least two sub-spinning parts in the device respectively.

[0066] In this embodiment, the electrospinning device 12 also includes at least one auxiliary adding device provided on each sub-spinning element. The auxiliary adding device is connected to the liquid outlet channel of the corresponding sub-spinning element. The auxiliary adding device is used to provide photosensitive components to the spinning solution that is separated from the sub-spinning element through the liquid outlet channel. Under this setting, the photosensitive components provided in different auxiliary adding devices may be different from each other. In this embodiment, by separately providing corresponding auxiliary adding devices on different sub-spinning elements, the spinning jets formed from different sub-spinning elements can respectively carry different photosensitive components. Different photosensitive components form a certain contrast between the colors presented after absorbing light energy, and the contrast can be captured and identified by the first image acquisition component 10.

[0067] Preferably, the monitoring system configures the number of light control components 14 according to the number of camera components in the image acquisition component. When the image acquisition component is provided with two camera components, a light control component 14 is configured correspondingly, and the light control component 14 can be arranged on the track together with the camera component. The light control component 14 maintains a synchronous motion state with the camera component.

[0068] Preferably, the electrospinning device 12 has an output end for delivering the spinning layer 13 and a collecting substrate.

[0069] The first camera assembly of the image acquisition assembly is arranged at a first position outside the electrospinning device 12 close to the output end.

[0070] The first camera assembly is configured to monitor markings on a collection substrate transmitted from an output end of the electrospinning device 12 .

[0071] As the collecting substrate is conveyed, at the first moment when the first mark and the second mark appear simultaneously on the collecting substrate conveyed from the output end of the electrospinning device 12, the first camera component starts to accelerate along its track from the first position and maintains the current speed at the second moment when its speed is consistent with that of the collecting substrate.

[0072] As the collecting substrate is conveyed, at the first moment when the first mark and the second mark appear simultaneously on the collecting substrate conveyed from the output end of the electrospinning device 12, the first light control component 14 corresponding to the current first camera component is triggered to project regional light to the limited area between the two marks on the spinning layer 13 / collecting substrate with the first mark and the second mark as the boundary. At the same time, the first light control component 14 keeps synchronous movement with the first camera component.

[0073] As the collection substrate is transferred, at the third moment obtained by superimposing the preset time period at the first moment, the first camera component and the light receiver are triggered to enter the working state, and the first camera component takes and identifies the image of the spinning layer 13 at the second position at the third moment, and the light receiver detects the light in the area after it is projected through the spinning layer 13 and transmits the detection data to the third data processing module for processing and analysis. In this way, the information collection process of the spinning layer 13 within a single image collection cycle is completed. Preferably, triggering the first camera component and the light receiver to enter the working state can refer to triggering each of them to perform image collection or light detection. Before that, the first camera component and the light receiver can both be in a sleep state to reduce power consumption.

[0074] Among them, the third moment should not be earlier than the second moment. Since the moving speed of the collection substrate is obtainable and usually a constant speed, the second moment can be determined by pre-calculating the time required for the first camera component and the first light control component 14 to accelerate from the start to the moving speed of the collection substrate. Based on this, a preset time period can be set in advance so that the third moment is not earlier than the second moment.

[0075] The preset time period is preset in advance and is set according to the time required for the projected regional light to cause the photosensitive particles in the spinning layer 13 to undergo energy transition and develop color. Since the fibers in the spinning layer 13 are relatively thin, the specific surface area is relatively large, and the energy absorption rate is fast, the setting of the preset time period can usually cover the time required for the projected regional light to cause the photosensitive particles in the spinning layer 13 to undergo energy transition and develop color.

[0076] Among them, since the regional light is projected after the local spinning layer 13 corresponding to a single image acquisition cycle completely moves out of the electrospinning device 12, the duration of the local spinning layer 13 being irradiated by the regional light can be made substantially consistent, ensuring better comparability between different color developments formed on the local spinning layer 13. At the same time, by projecting regional light to the local spinning layer 13 to develop its color, the first camera assembly and the first light control assembly 14 start to accelerate along their tracks from the first position until their speed is consistent with that of the collection substrate, and by using the above-mentioned setting mode of tracking shooting, the image quality of the first image acquisition assembly 10 is further effectively improved, while also ensuring that the local spinning layer 13 has relatively sufficient time to achieve the expected color development.

[0077] The second camera assembly of the image acquisition assembly is arranged at a first position outside the electrospinning device 12 close to the output end.

[0078] The second camera assembly is configured to monitor markings on a collection substrate transmitted from an output end of the electrospinning device 12 .

[0079] As the collecting substrate is conveyed, at the fourth moment when the second mark and the third mark appear simultaneously on the collecting substrate transmitted from the output end of the electrospinning device 12, the second camera component starts to accelerate along its track from the first position and maintains the current speed at the fifth moment when its speed is consistent with that of the collecting substrate.

[0080] As the collecting substrate is transmitted, at the fourth moment when the second mark and the third mark appear simultaneously on the collecting substrate transmitted from the output end of the electrospinning device 12, the second light control component 14 corresponding to the current second camera component is triggered to project regional light to the limited area between the two marks on the spinning layer 13 / collecting substrate with the second mark and the third mark as the boundary, and the second light control component 14 keeps synchronous movement with the second camera component.

[0081] As the collection substrate is transferred, the sixth moment obtained by superimposing the preset time period at the fourth moment triggers the second camera assembly and the light receiver to start, and the second camera assembly takes and identifies the image of the spinning layer 13 at the second position or the third position at the sixth moment, and the light receiver detects the light in the area after it passes through the spinning layer 13 and transmits the detection data to the third data processing module for processing and analysis. In this way, the information collection process of the spinning layer 13 in the second image collection cycle is completed.

[0082] During the movement of the second camera assembly, the first camera assembly ends its corresponding first image acquisition cycle including the first mark and the second mark, and returns from the second position to the first position along its track, so that the two camera assemblies perform image acquisition alternately.

[0083] The intermittent projection of regional light mentioned in this embodiment may also refer to the two light control components 14 alternately projecting regional light in time, or may refer to the two light control components 14 projecting on different local spinning layers 13 in the projection area. When two adjacent marks appear on the collection substrate transmitted from the output end of the electrospinning device 12 at the same time, the light control component 14 corresponding to the current camera component is triggered to project regional light to the limited area between the two marks on the spinning layer 13 / collection substrate with the two adjacent marks as the boundary. In addition, during the time from the moment when the light control component 14 projects the regional light to the spinning layer 13 to the moment when the light control component 14 realizes synchronization with the transmission speed of the collection substrate, or in the time period from the first moment to the third moment, the light control component 14 projects the regional light to the spinning layer 13 in at least two different projection modes, and while providing energy light for the photosensitive components in the spinning layer 13 to develop color, the deviation between the projection direction and the preset projection direction is determined, and the deviation is corrected.

[0084] Since the collecting substrate between the electrospinning device 12 and the substrate conveyor is not absolutely in the horizontal plane, the outlet end of the electrospinning device 12 and the conveying gap of the substrate conveyor may not be in the same plane, and the collecting substrate is conveyed at a slightly inclined angle relative to the horizontal plane. In this case, whether it is the image acquisition component or the light control component 14, the image acquisition or light projection is proposed on the basis of assuming that the collecting substrate is parallel to the horizontal plane, ignoring the deflection angle error. In this regard, in order to further improve the detection accuracy, the applicant sets a test scheme in which the light control component 14 projects regional light to the spinning layer 13 in at least two different projection modes, determines the deviation between the projection direction and the preset projection direction, and corrects the deviation. The applicant compares it with the test scheme of assuming that the collecting substrate is parallel to the horizontal plane for light projection and image acquisition. Taking the spinning layer 13 formed by actual spinning, in a static state, on the basis of ensuring that the collecting substrate is parallel to the horizontal plane, the actual spinning information such as thickness, color development, density, etc. obtained by the industrial-grade camera is used as the preset evaluation standard. Further, the test first forms a certain area of ​​the test spinning layer 13 through the electrospinning device 12, simulates the normal situation with a certain projection deviation, transmits the collection substrate at a certain speed, and uses the light control component 14 and the image acquisition component to first obtain the test results of the comparison group 1. Then the applicant uses the same test spinning layer 13 to simulate the light control component 14 that projects regional light to the spinning layer 13 in at least two different projection modes, determines the deviation between the projection direction and the preset projection direction, and corrects the deviation, transmits the collection substrate at a certain speed, and uses the light control component 14 and the image acquisition component to first obtain the test results of the comparison group 2. After completing the tests of comparison groups 1 and 2, the applicant manually adjusts the test spinning layer 13 to be parallel to the horizontal plane using a horizontal measuring instrument, and at the same time adjusts the light control component 14 and the image acquisition component to be parallel to the horizontal plane, keeps the collection substrate in a static state, and first obtains the test results of the evaluation group as the preset evaluation standard using the light control component 14 and the image acquisition component. The applicant found that the average value of the deviation between the test results of the test scheme with corrected projection deviation and the preset evaluation standard was about 1%, and the average value of the deviation between the test results of the test scheme without corrected projection deviation and the preset evaluation standard was about 5%. The deviation between the test results of the test scheme with corrected projection deviation and the preset evaluation standard was significantly smaller.

[0085] The following is a technical solution for projecting regional light from the light control component 14 to the spinning layer 13 in at least two different projection modes, determining the deviation between the projection direction and the preset projection direction, and correcting the deviation. Non-spinning areas are pre-set on the collecting substrate and located on both sides thereof. The non-spinning areas will not be exposed to the space where the spinning jet is formed, so there is basically no spinning on the non-spinning areas coming out of the electrospinning device 12. Two different projection modes may refer to the light-emitting components at at least two different positions on the light control component 14 emitting light of different wavelengths in the same emission direction to the spinning layer 13, and detecting the light after passing through the spinning layer 13 and the collecting substrate, and determining the current deviation between the current projection direction and the collecting substrate according to the difference in the amount of received light of different wavelengths detected. The light-emitting components at two different positions may refer to two light-emitting components located in the same first direction. The preset projection direction may refer to a preset angle between the projection direction of the light control component 14 and the collecting substrate. According to the current deviation between the current projection direction and the collecting substrate, and the preset projection direction, the deviation between the projection direction and the preset projection direction is determined. Based on the deviation, the angles of the light control component 14 and the image acquisition component are rotated so that the deviation is eliminated.

[0086] Preferably, after rotating the angles of the light control component 14 and the image acquisition component, the light control component 14 again projects regional light to the spinning layer 13 in at least two different projection modes to determine whether the deviation between the projection direction and the preset projection direction is eliminated.

[0087] In addition, the plane formed by the collecting substrate itself may not only have a certain inclination angle with the horizontal plane in the vertical direction, but also have a certain inclination angle with the horizontal plane in the horizontal direction. In order to further reduce the error, the two different projection modes may refer to the light-emitting components at at least three different positions on the light control component 14 emitting light of different wavelengths to the spinning layer 13 in the same emission direction, and detecting the light after passing through the spinning layer 13 and the collecting substrate, and determining the current deviation between the current projection direction and the collecting substrate according to the difference in the amount of received light of different wavelengths detected. The current deviation at least includes the first inclination angle formed by the plane formed by the collecting substrate itself in the vertical direction relative to the horizontal plane, and the second inclination angle formed in the horizontal direction relative to the horizontal plane. The light-emitting components at three different positions may refer to two first light-emitting components and a second light-emitting component located side by side in the first direction, and a third light-emitting component located side by side with the first light-emitting component or the second light-emitting component in the third direction. The third direction refers to a direction perpendicular to the first direction and the second direction, that is, the length extension direction of the above-mentioned horizontal frame.

[0088] The projection of regional light triggers the image acquisition component to capture images of the spinning layer 13 and identify and obtain local fiber distribution information about the spinning layer 13. The projection of regional light triggers the image acquisition component, which does not mean that the image acquisition action of the first image acquisition component 10 is triggered as soon as the projection operation of the regional light is detected. The projection of regional light is only one of the necessary conditions for triggering the image acquisition action of the first image acquisition component 10. Based on the regional light, when the duration of the regional light projection meets the preset time period, the image acquisition component is triggered to capture and identify the spinning layer 13. By setting the trigger conditions, the amount of invalid image acquisition data is reduced, which is conducive to improving data processing efficiency. At the same time, by setting marks to divide each image acquisition cycle, it is conducive to avoiding a large amount of repeated and cumbersome image acquisition data between different image acquisition components, and data processing is simpler and more effective.

[0089] The light control component 14 is configured to project regional light onto the spinning layer 13 to obtain regional density distribution information about the spinning layer 13 based on the regional light.

[0090] The regional light mentioned in this embodiment can be monochromatic light or composite light. The region refers to the region of the spinning layer 13 located on the side where the output end of the electrospinning device 12 is located. Further, the region is the corresponding region on the spinning layer 13 determined according to different image acquisition cycles. The light at least includes light that can trigger the color change of the photosensitive component.

[0091] Among them, the regional density distribution information mentioned in this embodiment may refer to the density distribution of nanofibers in the spinning layer 13 in the area monitored by the first image acquisition component 10. By detecting the light passing through the spinning layer 13 or reflected by the spinning layer 13 through the light monitor, the change in the amount of light can be obtained, and the density distribution of the fibers on the spinning layer 13, that is, the regional density distribution information, can be determined based on the change in the amount of light. Among them, the working parameters of the electrospinning device 12 are usually set according to the expected spinning layer fiber density during spinning, that is, the expected spinning layer fiber density can be used to determine whether the regional density distribution information meets the requirements.

[0092] In this embodiment, after acquiring the image data, the image acquisition component may first extract the effective area corresponding to the mark on the image data. Since the diameter of the spinning layer fiber is relatively small, the effective area needs to be divided into several small areas for sequential or simultaneous processing. Therefore, when processing a single small area, each small area needs to be magnified by the same preset multiple to obtain the color distribution in each small area. Preferably, while processing the color distribution of each small area, fiber distribution data or image simulation data corresponding to different colors are obtained according to different colors, so that the local fiber distribution information can be determined.

[0093] Among them, since the spinning layer 13 is formed by ejecting the spinning jet formed by multiple rows of transverse frames onto the collecting substrate in sequence, that is, the position closer to the collecting substrate in the spinning layer 13 with a certain thickness is more of the first part of the fibers formed by the first transverse frame near its inlet end in the electrospinning device 12, and the fibers formed by the second transverse frame adjacent to the sub-spinning element are captured by the collecting substrate in a form similar to covering the first part of the fibers. That is, the first formed fibers will always be partially obscured by the later formed fibers. Therefore, for the collected image data, in order to ensure a more accurate color distribution, a proportional threshold for correcting the fiber distribution data or image simulation data is preset in advance. The proportional threshold can be stored in a manner in which the transverse frames corresponding to different numbers correspond to a preset value respectively. For example, the ratio threshold is Horizontal Frame No. 1: Horizontal Frame No. 2: Horizontal Frame No. 3 = 0.6: 0.8: 1, which means that the color rendering amount that can be reflected in the image data of Horizontal Frame No. 1 is 60% of the whole, which means that the color rendering amount that can be reflected in the image data of Horizontal Frame No. 2 is 80% of the whole, which means that the color rendering amount that can be reflected in the image data of Horizontal Frame No. 3 is the complete whole color rendering amount. To avoid redundancy, Lx is used to represent different horizontal frames, for example, L1 is horizontal frame No. 1, and L2 is horizontal frame No. 2.

[0094] Among them, the applicant designed relevant experiments to simulate the above situation, and obtained the spinning layers 13 of different comparison groups by setting the electrospinning device 12 under different working parameters. The different working parameters mainly refer to that only one transverse frame is spun at a time to obtain the first layer of spinning, and then the first layer of spinning is re-transmitted into the electrospinning device 12 to operate another transverse frame for spinning to obtain the second layer of spinning covering the first layer of spinning. By performing image recognition analysis on the two layers of spinning respectively, the coverage ratio can be determined. Similarly, the coverage ratio of the third layer of spinning to the second layer of spinning can be determined, that is, the above-mentioned preset ratio threshold. The applicant repeated the above operations and distributed the obtained ratio data to determine the preset ratio threshold when the number of transverse frames is not more than five. Specifically, when the number of transverse frames is three, L1:L2:L3=(0.4~0.7):(0.5~0.8):1. When the number of transverse racks is four, L1: L2: L3: L4 = (0.3-0.5): (0.4-0.7): (0.5-0.8): 1. When the number of transverse racks is five, L1: L2: L3: L4: L5 = (0.3-0.5): (0.3-0.5): (0.4-0.7): (0.5-0.8): 1. Preferably, when the number of transverse racks is three, L1: L2: L3 = 0.6: 0.8: 1. When the number of transverse racks is four, L1: L2: L3: L4 = 0.4: 0.6: 0.8: 1. When the number of transverse racks is five, L1: L2: L3: L4: L5 = 0.4: 0.4: 0.6: 0.8: 1.

[0095] Among them, the color development amount in the correction image data, or the correction fiber distribution data or image simulation data, is mainly corrected by multiplying the color development amount determined according to the image data with a preset ratio threshold. For example, the ratio obtained by analyzing the image data is L1′: L2′: L3′: ...: Lx′=Z1: Z2: Z3: ...: Zx, and the preset ratio threshold is L1: L2: L3: ...: L x=i1: i2: i3: ...: ix. The image acquisition component corrects the ratio obtained by analyzing the image data to obtain: L1″: L2″: L3″: ...: Lx″=Z1*i1: Z2*i2: Z3*i3: ...: Zx*ix. The color development distribution in each small area can be L1″: L2″: L3″: ...: Lx″=Z1*i1: Z2*i2: Z3*i3: ...: Zx*ix. The above Lx′ and Lx″ respectively represent the color rendering amount (proportional value) determined according to the image data and the color rendering amount (proportional value) obtained after correction.

[0096] Wherein, the image acquisition component may be to divide the effective area into several small areas according to the first area division rule for sequential or simultaneous processing to obtain the color distribution in each small area. After obtaining the color distribution in each small area, the image acquisition component may be to divide the effective area into several large areas according to the second area division rule for sequential or simultaneous processing. The area division rule may refer to several blocks formed by crisscross virtual lines, and the size of the block indicates the size of the divided area. The area of ​​the block in the second area division rule is larger than that of the block in the first area division rule. Wherein, the second area division rule may be to dynamically determine the size of the block according to the color distribution in each small area determined based on the first area division rule. In the color distribution in each small area determined based on the first area division rule, when multiple statistical data on the difference between the proportional values ​​corresponding to any two sub-spinning parts are lower than the first statistical difference threshold, the shape of the block in the second area division rule is determined by the first area. The first statistical difference threshold can be set to 0.1. The shape of the block can be specified in the initial setting. For example, a circle, a triangle, a square or a polygon. Similarly, in the color distribution in each small area determined based on the first area division rule, when multiple statistical data about the difference between the proportion values ​​corresponding to any two sub-spinning members are higher than the first statistical difference threshold and lower than the second statistical difference threshold, the shape of the block in the second area division rule is determined by the second area. The first area can be a larger value than the second area.

[0097] Although the above-mentioned processing adopted for the collected image data can achieve a detection effect with a high degree of accuracy, on the other hand, since it is necessary to divide the acquired image area into regions each time, and further analyze and detect the divided regions, for the spinning layer 13 with a large number of fibers, especially the spinning layer 13 with a fiber distribution density that can meet the preset distribution requirements, since the monitoring system does not need to perform additional processing on such spinning layer 13, the image processing and analysis process with a certain amount of data processing is equivalent to redundant processing and analysis within the system, and the temporary storage of such data also occupies a certain amount of running memory. Although the single data redundancy will not affect the monitoring system, long-term continuous use or monitoring will lead to the gradual increase of temporary files in the system, which will seriously affect the running speed of the data processing module in a certain uncertain time period, and the spinning has to be stopped for maintenance.

[0098] In this regard, it is further preferred that the image acquisition component proposed in this embodiment can perform color value display judgment on the image data based on the third preset spinning condition after acquiring the image data, and determine the effective area in the regional spinning layer 13 corresponding to the current image acquisition cycle that needs to be further processed for image data. That is, after acquiring the image data, a color value display judgment is first performed, and before performing the first area division, a preliminary color value display analysis is performed on the image data with a smaller magnification degree / detail display degree. The color value display analysis result can be displayed in the form of a heat map, and the color display difference on the heat map can distinguish the area that meets the third preset spinning condition from the area that does not meet the condition.

[0099] Therefore, only a simple color value display judgment is needed to exclude unnecessary data in the image data, especially the spinning layer 13 whose fiber distribution density can meet the preset distribution requirements, because the monitoring system does not need to perform additional processing on such spinning layer 13. Therefore, through the above preprocessing, the redundant processing and analysis in the system is reduced to a certain extent. In addition, since the above preprocessing is aimed at image data with relatively low clarity, small overall data processing volume, and before regional division, the color value display judgment is efficient and will not bring additional excessive data processing pressure to the monitoring system. In addition, due to the visibility of the color value display analysis results, production personnel can call up and view the approximate situation of the spinning layer 13 under the current image acquisition cycle at any time, which is conducive to the realization of two-way supervision between the system and personnel.

[0100] The effective area mentioned in this embodiment may refer to a certain area in the image data or a set of some discontinuous areas.

[0101] Among them, the third preset spinning condition can change with the change of the working parameters of the electrospinning device 12. The third preset spinning condition can be manually set and adjusted by the production personnel at the initial stage of the operation of the electrospinning device 12. The third preset spinning condition includes a color value display threshold range. Since there are multiple different colors in the local spinning layer 13, if the fibers of the spinning layer 13 are evenly distributed, the multiple colors affect each other in the image data with a smaller degree of magnification or detail display, and a relatively vague color value display threshold range is formed. Correspondingly, in the case where the color of the photosensitive components configured in different sub-spinning parts or different transverse frames is different, since the proportion of the color development amount that can be collected by each photosensitive component in the image data is different, the color value display threshold range can be adaptively adjusted.

[0102] As a preferred embodiment, the image acquisition component proposed in this embodiment is configured to acquire the first image data at the first trigger moment and perform color value display judgment on the first image data. When determining the effective area that needs to be further processed in the spinning layer 13 corresponding to the current image acquisition cycle, the current moment is determined to be the second trigger moment, and the second image data is acquired based on the effective area at the second trigger moment.

[0103] Wherein, based on the first region division rule and / or the second region division rule, the image acquisition component processes the second image data and obtains local fiber distribution information.

[0104] The first image data has a first spinning layer clarity, the second image data has a second spinning layer clarity, and the first spinning layer clarity is lower than the second spinning layer clarity.

[0105] Under this setting, the image acquisition component performs image acquisition of the spinning layer 13 twice. The first image acquisition is only a rough acquisition with low clarity, fast acquisition rate, small image acquisition data, and fast data processing rate. On this basis, the acquisition area corresponding to the second image acquisition is determined. Compared with the traditional single acquisition with high-definition image acquisition processing method, it will not bring additional excessive data processing pressure to the monitoring system, and reduce the size of the area that requires high-definition acquisition. The reduction of the area that requires high-definition acquisition greatly reduces the amount of data processing and further reduces the redundant processing and analysis in the system. To a certain extent, the reduction of the area corresponding to high-definition acquisition can promote the improvement of the image data processing efficiency of the monitoring system.

[0106] The first triggering moment and the second triggering moment are only used to distinguish the first moment and the second moment in expression, and do not absolutely represent a corresponding relationship or a completely non-corresponding relationship between the two.

[0107] As another preferred embodiment, the image acquisition component proposed in this embodiment is configured to acquire the third image data at the third spinning layer clarity at the third trigger moment. When the third image data is adjusted to the fourth spinning layer clarity, the third image data is judged for color value display. When determining the effective area that needs to be further processed in the regional spinning layer 13 corresponding to the current image acquisition cycle, the fourth image data corresponding to the effective area in the third image data is extracted as the third spinning layer clarity.

[0108] Wherein, based on the first region division rule and / or the second region division rule, the image acquisition component processes the fourth image data and obtains local fiber distribution information.

[0109] Among them, the clarity of the third spinning layer is greater than the clarity of the fourth spinning layer.

[0110] Under this setting, the image acquisition component only captures one image of the spinning layer 13, and this image acquisition is a high-definition and accurate acquisition, without the need to repeat the secondary image acquisition. And after obtaining the image data, the entire high-definition image is not processed immediately, but its clarity is first adjusted to convert it into a low-definition image with a smaller data processing volume, and a color value display analysis is performed on it, thereby eliminating unnecessary redundant processing and analysis of the spinning layer 13 in the entire image, especially the fiber distribution density that can meet the preset distribution requirements. In further high-definition data processing, the amount of data required for processing after the above preprocessing is greatly reduced, and the redundant processing and analysis in the system is further reduced. Due to the reduction of the area corresponding to high-definition acquisition, the image data processing efficiency of the monitoring system can be improved.

[0111] In addition, the first trigger moment / the second trigger moment and the third trigger moment are only used to distinguish different preferred embodiments in expression, and do not absolutely refer to completely different meanings from each other. Similarly, the first image data / the second image data and the third image data / the fourth image data are only used to distinguish different preferred embodiments in expression, and do not absolutely refer to completely different meanings from each other. Similarly, the first spinning layer clarity / the second spinning layer clarity and the third spinning layer clarity / the fourth spinning layer clarity are only used to distinguish different preferred embodiments in expression, and do not absolutely refer to completely different meanings from each other.

[0112] In this embodiment, the light control component 14 is used to project regional light onto the spinning layer 13 formed by the electrospinning device 12. The photosensitive components in the spinning layer 13 absorb the light energy and display color. The image acquisition component captures the image of the colored spinning layer 13 and determines the associated sub-spinning component based on image recognition.

[0113] The first data processing module 11 obtains spinning state information about at least one sub-spinning element based on at least the regional density distribution information and the local fiber distribution information.

[0114] After the image acquisition component obtains the local fiber distribution information about the spinning layer 13 through image recognition, the regional density distribution information indicates whether there is an abnormal density distribution and the area where the abnormal density distribution occurs. The local fiber distribution information can further indicate which sub-spinning component in such an area has an abnormal spinning state, which causes the abnormal fiber distribution in the area. Correspondingly, in the case of an area where there is no abnormal density distribution, the first data processing module 11 can use the regional density distribution information and the local fiber distribution information as the spinning state information of each sub-spinning component in a certain working time period.

[0115] The first data processing module 11 obtains spinning state information about at least one sub-spinning element based on at least the regional density distribution information and the local fiber distribution information.

[0116] The spinning state information of the sub-spinning element mentioned in this embodiment may refer to the difference between the current sub-spinning element and the preset spinning state. The preset spinning state changes with the change of the working parameters of the electrospinning device 12, which is specifically reflected in the number and distribution of nanofibers related to the sub-spinning element on the spinning layer 13. When there is no blockage at the outlet end of the sub-spinning element, such as residual spinning jets, the outlet end of the sub-spinning element can form a stable and predictable distribution of nanofibers in a certain area. Then, combined with the real-time information related to the spinning layer 13 obtained by the optical control component 14 and other equipment, such as regional density distribution information and / or local fiber distribution information, the spinning state information of the sub-spinning element can be determined. The spinning state information can be normal operation or abnormal operation. Production personnel can quickly determine the current spinning state of each sub-spinning element.

[0117] Preferably, the photosensitive component / photosensitive particles used in this embodiment are photochromic materials or photochromic polymer materials. The photochromic phenomenon refers to the phenomenon that when a material is irradiated with light of a certain wavelength and intensity, a specific chemical reaction may occur and the material may change from state 1 to state 2. At this time, the color of the material or the peak absorption of light may change due to structural changes, but under the action of heat or light of another wavelength, the material may be restored from state 2 to its original molecular structure and apparent color. The whole process is reversible. Such a material that can undergo a reversible color change under the action of light is called a photochromic material. Its optical properties can be adjusted by changing the structure of organic molecules. Most photochromic materials can be activated by ultraviolet light in the range of 200 to 400 nm. Photochromic materials usually have different physical and chemical properties in different states. By adjusting the two states with light, the material properties can be regulated. For example, photosensitive component A is colorless. After being irradiated by ultraviolet rays, the molecule opens into a cyanine structure and becomes photosensitive component B, which is blue. When the ultraviolet rays disappear, photosensitive component B returns to colorless photosensitive component A.

[0118] The photosensitive component can be an organic photochromic material, and its color change mechanism mainly includes the breaking and combination of double bonds (bond homolysis, bond heterolysis), isomer production (proton transfer tautomerism, cis-trans isomerism), acid-induced color change, pericyclic reaction and redox reaction, etc. At present, the main research is mainly diarylethenes, such as 1-(4'-N, N-dimethylaminophenylazo) anthraquinone I and 1,2-(4'-N, N-dimethylaminophenylazo) anthraquinone II and other azobenzene derivatives, naphthoxy derivatives, fulgide derivatives, spiropyran or spirooxazine derivatives.

[0119] The photosensitive component can also be an inorganic photochromic material, such as rare earth complexes, transition metal oxides such as MoO3, WO3, V2O5, TiO2, polyoxometalates, and metal halides.

[0120] The photosensitive component can also be an inorganic-organic hybrid photochromic material. Inorganic-organic hybrid photochromic materials can be divided into: coordinated covalent bond binding type, ionic bond binding type and weakly bonded intercalation and mesoporous type according to different bonding methods. The color change mechanism includes: redox electron transfer, intercalation space structure, and reversible change of T-electron conjugation characteristics of photochromic molecules.

[0121] Preferably, the regional light used in this embodiment is mainly a combination of visible light and light corresponding to the photosensitive component, such as ultraviolet light. Preferably, the color of the photosensitive components for different sub-spinning parts used in this embodiment under visible light is white or transparent.

[0122] According to a preferred embodiment, the first preset spinning condition regarding the spinning layer density distribution is preset in the first data processing module 11. Preferably, the first preset spinning condition can change with the change of the working parameters of the electrospinning device 12. Among them, the first preset spinning condition can be a preset spinning layer density. When the first data processing module 11 monitors the change of the working parameters of the electrospinning device 12 controlled by the production personnel, it determines whether the first preset spinning condition needs to be adjusted, and when it is determined to be necessary, the first preset spinning condition is adjusted to data corresponding to the current working parameters according to the pre-stored adjustment strategy.

[0123] When it is detected that the regional density distribution information generated by the light control component 14 triggers the first preset spinning condition, the first data processing module 11 determines at least one sub-spinning component in the electrostatic spinning device 12 corresponding to the trigger in combination with the local fiber distribution information. The triggering of the first preset spinning condition may be that the regional density distribution information is lower than the minimum value of the range of the first preset spinning condition or higher than the maximum value of its range. That is, the density distribution of a certain part of the monitored area on the spinning layer 13 is too sparse or too dense, triggering the first preset spinning condition. Then, the local fiber distribution information corresponding to the local area is obtained, and the further refined fiber distribution data corresponding to the sub-spinning components of the local area can be used to determine the sub-spinning components in the area with abnormal density distribution due to the lack of fibers corresponding to one or some sub-spinning components. This can better achieve accurate determination of sub-spinning components with spinning abnormalities.

[0124] Preferably, the monitoring system proposed in this embodiment may include wall slides installed on two inner walls opposite to each other and arranged in parallel along a third direction in the electrospinning device 12, and frame slides installed on the side of the transverse frame along the length extension direction of the transverse frame, i.e., the third direction, and a cleaning component. A plurality of frame slides extend along the third direction and their two ends are respectively connected to two wall slides opposite to each other. The cleaning component is slidably connected to the wall slides and can slide back and forth between the wall slides and the frame slides. When the cleaning component slides on the wall slides, it is in a standby state; when it slides on the frame slides, it is in a working state. The cleaning portion on the cleaning component can sweep from the top of the sub-spinning element or the nozzle to take away the residues such as spinning liquid remaining on the sub-spinning element that affect the spinning effect.

[0125] Usually, the electrospinning device 12 is provided with a large number of thresholds, and the thresholds are directly related to the working parameters of each device in the electrospinning process. The working parameter thresholds are set separately for each device. However, in fact, each device does not work independently. The changes in the working parameters of each device may not affect the electrospinning process after being superimposed on each other, and can still meet the electrospinning output requirements. Therefore, this setting is prone to frequent false alarms, increasing the workload of maintenance personnel and affecting the spinning efficiency. In this regard, the present embodiment directly monitors the spinning layer 13 obtained by spinning, and sets a preset spinning condition for the density distribution of the spinning layer. When the density distribution of the monitored area on the spinning layer 13 is too sparse or too dense, the preset spinning condition is triggered, and the sub-spinning parts that affect the spinning situation can be further determined in combination with the local fiber distribution information, which is conducive to maintenance personnel to perform equipment maintenance work more efficiently.

[0126] In this embodiment, when intermittently projecting regional light to the spinning layer 13 captured by the collecting end adjustment device 9 and leaving the electric field area with the collecting substrate, the light control component 14 can obtain regional thickness distribution information about the spinning layer 13 based on the regional light. The first data processing module 11 obtains the electric field state information about at least one sub-spinning element based on at least the regional thickness distribution information and the regional density distribution information. On the basis of setting the above-mentioned density abnormality trigger detection mechanism, this embodiment also superimposes the thickness abnormality trigger detection mechanism. By acquiring and analyzing the regional thickness distribution information, the spinning layer 13 can be analyzed from a higher acquisition dimension in combination with the regional density distribution information, especially when the spinning layer density is normal but the spinning layer thickness is abnormal, it can be determined whether there is abnormal fluctuation in the electric field related to at least one sub-spinning element. That is, the spinning layer 13 reflects whether there is a fluctuation in the electric field that really affects the spinning result, rather than just monitoring by setting an overly strict working parameter threshold. In the event of abnormal fluctuations in the electric field, the first data processing module 11 can directly point out that there are abnormal fluctuations in the electric field of one or some of the sub-spinning elements without having to check the electric field area in the entire electrospinning device 12, thereby improving production efficiency and reducing unnecessary workload for maintenance personnel.

[0127] In this embodiment, the regional thickness distribution information may refer to the thickness distribution of the nanofibers in the spinning layer 13 in the area monitored by the first image acquisition component 10. The regional thickness distribution information may be obtained by collecting light projected onto the spinning layer 13 and detecting and analyzing the light.

[0128] In this embodiment, the electric field state information may refer to whether the electric field fluctuates to affect the spinning process.

[0129] In this embodiment, the first data processing module 11 is preset with a second preset spinning condition regarding the thickness distribution of the spinning layer. When the second preset spinning condition is detected to be triggered by the regional thickness distribution information generated by the light control component 14, the first data processing module 11 determines at least one sub-spinning element in the electrospinning device 12 corresponding to the trigger in combination with the regional density distribution information. Preferably, the second preset spinning condition can change with the change of the working parameters of the electrospinning device 12.

[0130] In this embodiment, the second preset spinning condition regarding the thickness distribution of the spinning layer is preset in the first data processing module 11. Preferably, the second preset spinning condition may change with the change of the working parameters of the electrospinning device 12. Among them, the second preset spinning condition may be a preset spinning layer thickness. Furthermore, the second preset spinning condition should be set according to the thickness of the spinning layer 13 before it passes through the substrate conveyor, that is, just after the electrospinning is finished. When the first data processing module 11 monitors the change of the working parameters of the electrospinning device 12 controlled by the production personnel, it determines whether the second preset spinning condition needs to be adjusted. When it is determined to be necessary, the second preset spinning condition is adjusted to the data corresponding to the current working parameters according to the pre-stored adjustment strategy.

[0131] In this embodiment, the system also includes a secondary electrospinning device 12 and a second data processing module connected to the device. The collection substrate output by the above-mentioned electrospinning device 12 enters the secondary electrospinning device 12 with the spinning layer 13 for multi-layer electrospinning. The second data processing module can obtain regional density distribution information about the spinning layer 13 currently entering the secondary electrospinning device 12. The second data processing module adjusts the working parameters of at least one sub-spinning member in the secondary electrospinning device 12 accordingly. The second data processing module can be used to compensate for the non-uniform density distribution of the spinning layer 13.

[0132] In order to achieve a spinning layer 13 of a certain thickness, two or more electrospinning devices 12 are often used in series. The spinning layer 13 from the previous electrospinning device 12 enters the next electrospinning device 12 to continue spinning. However, the electrospinning devices 12 usually work according to the preset working parameters. When the spinning layer 13 outputted finally has uneven density or thickness problems, it is impossible to confirm which device or which link caused it. Moreover, due to the layer-by-layer spinning layer 13, it is impossible to make up for the large defects in the middle. In this regard, the monitoring system proposed in this embodiment is particularly suitable for the case where two electrospinning devices 12 are connected in series with each other. The spinning layer 13 outputted by the previous electrospinning device 12 is monitored and analyzed in real time through multiple components. The defects and defect conditions of the spinning layer 13 to be inputted into the next electrospinning device 12 can be better determined, so that the compensation scheme executed by the next electrospinning device 12 can be correspondingly determined, so as to timely discover the defect problems and timely feedback and solve them, which is more conducive to achieving the ideal spinning effect.

[0133] In this embodiment, the electrospinning device 12 can provide spinning solutions with different components to at least two sub-spinning parts in the device respectively. The second data processing module can obtain regional density distribution information about the spinning layer 13 currently entering the secondary electrospinning device 12. The second data processing module can obtain local fiber distribution information related to the regional density distribution information. The second data processing module adjusts the working parameters of at least one sub-spinning part in the secondary electrospinning device 12 accordingly to compensate for the non-uniform density distribution of different components in the spinning layer 13.

[0134] Example 3

[0135] This embodiment may be a further improvement and / or supplement to the above-mentioned embodiment, and repeated contents will not be repeated. In the case of no conflict or contradiction, the whole and / or part of the preferred implementation manner of other embodiments may be used as a supplement to this embodiment.

[0136] This embodiment proposes a system and method for monitoring the working state of a spinning element in electrospinning. The system at least includes a first data processing module 11 .

[0137] In this embodiment, the first data processing module 11 pre-stores the first to third preset spinning conditions, and the first data processing module 11 monitors and analyzes the regional density distribution of the spinning layer 13 based on the first preset spinning condition, and simultaneously or asynchronously monitors and analyzes the regional thickness distribution of the spinning layer 13 based on the second preset spinning condition. When the regional density distribution of the current local spinning layer 13 is lower than the minimum value of the range set in the first preset spinning condition, or when the regional density distribution of the current local spinning layer 13 is higher than the maximum value of the range set in the first preset spinning condition, regardless of the judgment result of the second preset spinning condition, at least one sub-spinning component with abnormal working state / abnormal fluctuation is determined, and the regional fiber distribution of the spinning layer 13 is monitored and analyzed based on the third preset spinning condition, and at least one sub-spinning component to be checked is determined. That is, when the density distribution of the spinning layer 13 deviates from the first preset spinning condition, regardless of the thickness of the spinning layer, it is necessary to determine at least one sub-spinning component that causes the deviation according to the third preset spinning condition.

[0138] When the regional density distribution of the current local spinning layer 13 is lower than the minimum value of the range set in the second preset spinning condition, the first preset spinning condition is judged. If the regional density distribution of the current local spinning layer 13 is not lower than the minimum value of the range set in the first preset spinning condition, at least one sub-spinning part corresponding to its position may have abnormal positive fluctuations in the electric field is determined. That is, when the thickness distribution of the spinning layer 13 is too thin, if the density of the spinning layer 13 at this time is sparser than the normal spinning density range, it means that the electric field has abnormal positive fluctuations. In this embodiment, the abnormal positive fluctuation of the electric field refers to the fluctuation of the originally stable voltage with an increasing trend. The increasing fluctuation of the voltage causes the force acting on the spinning layer 13 at a certain location to increase, so that the thickness of the spinning layer 13 at that location becomes abnormal, that is, thin.

[0139] When the regional density distribution of the current local spinning layer 13 is higher than the maximum value of the range set in the second preset spinning condition, the first preset spinning condition is judged. If the regional density distribution of the current local spinning layer 13 is not higher than the maximum value of the range set in the first preset spinning condition, at least one sub-spinning part corresponding to its position may have abnormal negative fluctuations in the electric field is determined. That is, when the thickness distribution of the spinning layer 13 is too thick, if the density of the spinning layer 13 at this time is denser than the normal spinning density range, it means that the electric field has abnormal negative fluctuations. In this embodiment, the abnormal negative fluctuation of the electric field refers to the fluctuation of the stable electric field voltage with a decreasing trend. The fluctuation of the voltage with a decreasing trend causes the force acting on the spinning layer 13 at a certain location to decrease, so that the thickness of the spinning layer 13 at that location is abnormal, that is, too thick.

[0140] In this embodiment, the thickness of the spinning layer 13 shall refer to the distance between the fibers which are farthest from each other in the third direction perpendicular to the collecting substrate when the spinning layer 13 having pores formed therein is not subjected to pressure from the substrate conveyor.
