[0053] An output module is configured to weigh the detection container when the pouring is stopped, and determine the actual continuous adsorption amount of the adsorbent according to the weighing result.
[0054] Compared with the prior art, the beneficial effect of the present invention lies in that the present invention can more accurately capture the diffusion rate and adsorption state of the adsorbent at different time points by real-time acquisition and analysis of images during the adsorption process, thereby generating an accurate actual diffusion curve. Compared with the traditional method, the image-based real-time monitoring method can reduce human errors and improve the accuracy and reliability of the test; the initial pouring rate is dynamically adjusted according to the analysis result of the first actual diffusion curve to obtain the first actual pouring rate, and pouring is performed at this rate in the subsequent process; the dynamic adjustment mechanism can ensure that the adsorption process is carried out under optimal conditions, improve the adsorption efficiency, and avoid the adsorption surplus or failure to reach adsorption saturation; when the second actual adsorption parameter reaches the preset standard adsorption saturation condition, the pouring is stopped, ensuring that the adsorbent can fully reach its adsorption capacity, avoiding excessive or insufficient pouring, thereby ensuring the accuracy and effectiveness of the test results; the entire test process is significantly reduced by automated control and real-time analysis, and the test efficiency is improved; by performing continuous pouring and real-time image acquisition in stages, the test of multiple detection points can be completed in a short time, further improving the overall test efficiency; and the accuracy of measuring the continuous adsorption amount is guaranteed.
[0055] In particular, by identifying and calculating the actual adsorption area in the first adsorption image, and calculating the real-time diffusion rate based on the area difference and the initial time interval, the accuracy of the diffusion rate measurement is significantly improved; the entire process from image recognition to diffusion rate calculation is automated, reducing human intervention, thereby reducing data deviations caused by human errors. Automated processing not only improves efficiency, but also ensures data consistency and repeatability; in order to address problems such as insufficient edge clarity, incomplete contours, abnormal contour shapes, or insufficient contour symmetry that may appear in the image, a contour correction mode is introduced; by adjusting the brightness difference inside and outside the contour of the marked area, the contour features of the image are improved, so that the actual adsorption area identified is more accurate, and the reliability of the diffusion rate calculation is further improved; it can process images of different qualities, including those with noise, blur or deformation; through the contour correction mode, even if the image quality is poor, relatively accurate diffusion rate measurement results can be obtained, reflecting the strong adaptability and robustness of the method; calculations are performed based on the adsorption image acquired in real time, so that real-time monitoring of the diffusion process can be achieved, and the measurement accuracy is improved.
[0056] In particular, by monitoring the diffusion rate in real time and comparing it with the preset standard diffusion rate, the adsorption capacity of the adsorbent can be evaluated instantly; it enables rapid response and timely adjustment of the pouring rate to prevent the adsorption surplus from occurring when the adsorbent continues to be poured at the initial pouring rate; and it is possible to quickly identify changes in the performance of the adsorbent; when the absolute value of the difference between the real-time diffusion rate and the standard diffusion rate reaches or exceeds the preset first evaluation value, it is determined that a first actual diffusion curve is generated, and the real-time diffusion rate at this time is used as the end point of the curve; this process actually provides an early warning for a possible decrease in adsorption capacity; this early warning mechanism helps to take measures in advance, such as adjusting operating conditions (adjusting the pouring rate), to prevent negative consequences caused by excessive or insufficient pouring.
[0057] In particular, by accurately identifying and analyzing the endpoint slope (first actual slope) of the first actual diffusion curve and its maintenance time, the actual state of the pouring process can be judged more accurately, thereby achieving fine adjustment of the pouring rate. The data-driven method is more accurate and reliable than the traditional empirical adjustment; the pouring rate can be dynamically adjusted according to the real-time changes in the diffusion curve rather than a fixed preset value; by timely adjusting the pouring rate, excessive pouring due to too fast pouring can be avoided, preventing the adsorbent from being unable to be fully adsorbed; or inaccurate measurement of the continuous adsorption amount of the adsorbent due to insufficient pouring can be avoided.
[0058] In particular, by simultaneously considering the endpoint slope of the second actual diffusion curve (the second actual slope) and its maintenance time (the second slope maintenance time) as the basis for determining the standard adsorption saturation condition, the saturation state of the adsorption process can be evaluated more accurately, which can better reflect the comprehensive effect of the adsorption process than a single indicator (such as only considering the slope or time); by setting a reasonable first standard slope and standard time as thresholds, it can be ensured that the pouring is stopped when the adsorption process has indeed reached the saturation state; avoiding insufficient adsorption due to premature stopping, or inaccurate measurement due to late stopping.
[0059] In particular, by evenly dividing the detection container and combining it with the acquisition module to collect adsorption images in real time, comprehensive and high-precision monitoring of the adsorption process is ensured. The refined monitoring method helps to capture subtle changes in the adsorption process and improve the accuracy and reliability of the data; the first analysis module and the second analysis module use advanced image processing and analysis technology to perform real-time analysis on the collected adsorption images, quickly and accurately determine the real-time diffusion rate and generate the actual diffusion curve. The intelligent analysis method not only improves work efficiency, but also reduces human errors and ensures the accuracy of the analysis results; according to the analysis results of the first actual diffusion curve, the initial pouring rate is dynamically adjusted to adapt to changes in the adsorption process, accurately judge whether the adsorption process reaches the preset standard adsorption saturation condition, and control the timing of stopping pouring accordingly, thereby ensuring the accuracy of measuring the continuous adsorption amount of the adsorbent.

[0077] The initial time interval is 2s;
[0078] The initial time interval is 1 / 10 of the total adsorption time of the adsorbent based on the historical test process.
[0079] Specifically, the embodiment of the present invention can more accurately capture the diffusion rate and adsorption state of the adsorbent at different time points by real-time acquisition and analysis of images during the adsorption process, thereby generating an accurate actual diffusion curve. Compared with traditional methods, the image-based real-time monitoring method can reduce human errors and improve the accuracy and reliability of the test; the initial pouring rate is dynamically adjusted according to the analysis results of the first actual diffusion curve to obtain the first actual pouring rate, and pouring is performed at this rate in the subsequent process; the dynamic adjustment mechanism can ensure that the adsorption process is carried out under optimal conditions, improve the adsorption efficiency, and avoid the adsorption surplus or failure to reach adsorption saturation; when the second actual adsorption parameter reaches the preset standard adsorption saturation condition, the pouring is stopped, ensuring that the adsorbent can fully reach its adsorption capacity, avoiding excessive or insufficient pouring, thereby ensuring the accuracy and effectiveness of the test results; the entire test process is significantly reduced by automated control and real-time analysis, and the test efficiency is improved; by performing continuous pouring and real-time image acquisition in stages, the test of multiple detection points can be completed in a short time, further improving the overall test efficiency; the accuracy of measuring the continuous adsorption amount is guaranteed.
[0080] Specifically, see Figure 2 As shown, it is a flow chart for determining the real-time diffusion rate, wherein the process of analyzing each first adsorption image and determining a plurality of real-time diffusion rates according to the analysis results includes:
[0081] Step S311, for any first adsorption image, identifying a shadow portion in the first adsorption image to obtain an actual adsorption area;
[0082] Step S312, calculating the area difference of the actual adsorption area in the first adsorption images acquired at adjacent initial time intervals, and calculating the real-time diffusion rate according to the area difference combined with the initial time interval;
[0083] Wherein, the real-time diffusion rate=area difference / initial time interval.
[0084] Specifically, the process of identifying the shadow portion in the first adsorption image to obtain the actual adsorption area in this embodiment includes:
[0085] Identifying a number of actual grayscale values in the first adsorption image, and marking an area where the actual grayscale value is less than a preset standard grayscale value to obtain a marked area;
[0086] Analyze the marked area to obtain contour features of the marked area, and determine whether to start a contour correction mode according to the contour features;
[0087] Based on the contour correction mode, differentially adjust the brightness inside and outside the contour of the marked area to obtain the target area;
[0088] Identifying the target area to obtain the actual adsorption area;
[0089] Wherein, based on the fact that the edge clarity of the contour feature is insufficient, it is determined to start the contour correction mode.
[0090] Optionally, when the adsorbent is cat litter, the cat litter is evenly spread in the detection container, any initial detection point in the detection container is selected as the target detection point, the target detection point is continuously poured at the initial pouring rate in the first process, and at an initial time interval, a first adsorption image of the cat litter in the target detection point is collected according to the image capture device, each actual grayscale value in the first adsorption image is identified, each actual grayscale value is analyzed, and an area where the actual grayscale value is less than a preset standard grayscale value is marked to obtain a marked area, and contour feature recognition is performed on the marked area to determine whether the contour feature has insufficient edge clarity, and when the contour feature is insufficient in edge clarity, the contour correction mode is turned on, and the brightness on both sides of the contour edge of the marked area is adjusted to enhance the contrast of the image, thereby making the contour edge clearer to obtain the target area, and the target area is the shadow part;
[0091] The specific process of contour correction of the marked area includes: using an edge detection algorithm to find the contour edge in the image. The edge detection algorithm can select Sobel operator, Canny edge detection, Prewitt operator, etc., as long as it can achieve the acquisition of the contour edge. This embodiment does not specifically limit the specific edge detection algorithm; when the contour edge is detected, the image is histogram equalized to improve the contrast of the image and make the edge more obvious, and then a local contrast enhancement technology, such as adaptive histogram equalization (such as CLAHE), is used to enhance the contrast near the edge, and then a sharpening filter, such as Laplacian or Sobel filter, is applied to enhance the clarity of the edge; finally, the edge is further enhanced by adjusting the brightness and contrast of the image; and the brightness difference on both sides of the edge is made more obvious.
[0092] Specifically, the embodiment of the present invention significantly improves the accuracy of diffusion rate measurement by identifying and calculating the actual adsorption area in the first adsorption image, and calculating the real-time diffusion rate based on the area difference and the initial time interval; the entire process from image recognition to diffusion rate calculation is automated, reducing human intervention, thereby reducing data deviations caused by human errors, and automated processing not only improves efficiency, but also ensures data consistency and repeatability; in order to address problems such as insufficient edge clarity, incomplete contours, abnormal contour shapes, or insufficient contour symmetry that may occur in images, a contour correction mode is introduced; by adjusting the brightness difference inside and outside the contour of the marked area, the contour features of the image are improved, so that the actual adsorption area identified is more accurate, and the reliability of diffusion rate calculation is further improved; it can process images of different qualities, including those with noise, blur or deformation; through the contour correction mode, even if the image quality is poor, a relatively accurate diffusion rate measurement result can be obtained, which reflects the strong adaptability and robustness of the method; calculations are performed based on the adsorption image acquired in real time, so that real-time monitoring of the diffusion process can be achieved, and measurement accuracy is improved.
[0093] Specifically, see Figure 3 As shown, it is a flow chart of determining whether to generate a first actual diffusion curve, wherein the process of determining whether to generate a first actual diffusion curve according to the real-time diffusion rate includes:
[0094] Step S321, calculating a first difference absolute value according to any of the real-time diffusion rates combined with a preset standard diffusion rate;
[0095] Step S322, determining whether to generate the first actual diffusion curve based on the first difference absolute value combined with a preset first evaluation value;
[0096] The absolute value of the first difference=|real-time diffusion rate-standard diffusion rate|;
[0097] Wherein, based on the absolute value of the first difference being greater than or equal to the first evaluation value, it is determined that the first actual diffusion curve is generated; and the real-time diffusion rate is determined to be the first curve end point of the first actual diffusion curve;
[0098] In a specific implementation process, the real-time diffusion rate obtained at each initial time interval is collected, and when the absolute value of the first difference corresponding to any real-time diffusion rate is greater than or equal to the first evaluation value, the first actual diffusion curve is generated according to the data of each collection point before the real-time diffusion rate (including the data of the collection point corresponding to the real-time diffusion rate);
[0099] The first actual diffusion curve is a curve showing a change of the real-time diffusion rate over time, the abscissa of the first actual diffusion curve is time, and the ordinate of the first actual diffusion curve is a specific value of the real-time diffusion rate;
[0100] In this embodiment, the standard diffusion rate is used to measure the adsorption capacity of the adsorbent; the first evaluation value is used to measure whether the adsorption capacity of the adsorbent decreases. When the absolute value of the first difference is greater than or equal to the first evaluation value, it is determined that the adsorption capacity of the adsorbent is abnormal, and the first actual diffusion curve is generated for further analysis.
[0101] Specifically, the embodiments of the present invention can instantly evaluate the adsorption capacity of the adsorbent by monitoring the diffusion rate in real time and comparing it with a preset standard diffusion rate; enable rapid response and timely adjustment of the pouring rate to prevent adsorption surplus from occurring when the adsorbent continues to be poured at the initial pouring rate; and achieve rapid identification of changes in adsorbent performance; when the absolute value of the difference between the real-time diffusion rate and the standard diffusion rate reaches or exceeds a preset first evaluation value, determine that a first actual diffusion curve is generated, and use the real-time diffusion rate at this time as the end point of the curve; this process actually provides an early warning for a possible decrease in adsorption capacity; this early warning mechanism helps to take measures in advance, such as adjusting operating conditions (adjusting the pouring rate) to prevent negative consequences caused by excessive or insufficient pouring.
[0102] Specifically, the process of determining whether to adjust the initial pouring rate based on the analysis result of the first actual diffusion curve in this embodiment includes:
[0103] Step S410, identifying the first actual diffusion curve to obtain a first actual slope corresponding to an end point of the first curve;
[0104] Step S420, determining whether the first actual slope meets a single adjustment condition according to the first actual slope combined with a preset standard slope evaluation interval;
[0105] Wherein, when the first actual slope is less than or equal to the second standard slope and greater than the first standard slope, it is determined that the first actual slope meets the single adjustment condition; the first standard slope is the upper limit value of the standard slope evaluation interval; the second standard slope is the lower limit value of the standard slope evaluation interval;
[0106] Step S430, based on the first actual slope meeting the single adjustment condition, obtaining a first slope maintenance time corresponding to the end point of the first curve;
[0107] Step S440, determining whether the first slope maintenance time meets the single adjustment condition according to the first slope maintenance time combined with a preset standard time;
[0108] Wherein, based on the first slope maintenance time being greater than or equal to the standard time, it is determined that the first slope maintenance time meets the single adjustment condition;
[0109] Step S450, determining the number of items in the first actual slope and the first slope maintenance time that meet the single adjustment condition;
[0110] Step S460, when the number of items is equal to 2, it is determined to adjust the initial pouring rate to obtain the first actual pouring rate;
[0111] Wherein, the first actual pouring rate = initial pouring rate × [1-(second standard slope-first actual slope) / second standard slope-(first slope maintenance time-standard time) / standard time];
[0112] In the specific implementation process, the first standard slope is used to measure the fluctuation rate of the real-time diffusion rate corresponding to different acquisition time intervals, and the first standard slope is set to 0-0.09; the second standard slope is set to 0.3-0.5; the standard time is set to 4s; and adaptive selection and adjustment are performed according to the actual measurement accuracy; the actual measurement accuracy required in this embodiment needs to reach more than 80%; for example, the first standard slope is set to 0.03, and the second standard slope is set to 0.4, then the standard slope evaluation interval is [0.03, 0.4], if the first actual slope obtained is 0.25, then within the standard slope evaluation interval, it is determined that the single adjustment condition is met, then the timing is started, and the corresponding first slope maintenance time is obtained, based on the first slope maintenance time being greater than or equal to 4s, it is determined that the first actual slope and the first slope maintenance time both meet the single adjustment condition, that is, the number of items is equal to 2, then it is determined that the initial pouring rate is adjusted to obtain the first actual pouring rate.
[0113] Specifically, the embodiment of the present invention can more accurately judge the actual state of the pouring process by accurately identifying and analyzing the endpoint slope (first actual slope) of the first actual diffusion curve and its maintenance time, thereby achieving fine adjustment of the pouring rate. The data-driven method is more accurate and reliable than the traditional empirical adjustment; the pouring rate can be dynamically adjusted according to the real-time changes in the diffusion curve, rather than a fixed preset value; by timely adjusting the pouring rate, excessive pouring due to too fast pouring can be avoided, preventing the adsorbent from being unable to be fully adsorbed; or avoiding inaccurate measurement of the continuous adsorption amount of the adsorbent due to insufficient pouring; and by further determining and analyzing the maintenance time of the first slope when the first actual slope meets a single adjustment condition, accidental events in the adsorption process can be avoided, making the measurement and adjustment results more accurate.
[0114] Specifically, in this embodiment, when the second actual adsorption parameter corresponding to the second actual diffusion curve reaches the preset standard adsorption saturation condition, the process of stopping pouring includes:
[0115] Step S610, identifying the second actual diffusion curve to obtain a second actual slope corresponding to an end point of the second curve;
[0116] Step S620, obtaining a second slope maintenance time corresponding to the end point of the second curve;
[0117] Step S630, when the second actual slope is less than or equal to the first standard slope and the second slope is maintained for a time greater than or equal to the standard time, it is determined that the second actual adsorption parameter reaches the standard adsorption saturation condition;
[0118] The second actual adsorption parameter includes: the second actual slope and the second slope maintenance time.
[0119] Specifically, the embodiment of the present invention can more accurately evaluate the saturation state of the adsorption process by simultaneously considering the endpoint slope (second actual slope) and the maintenance time (second slope maintenance time) of the second actual diffusion curve as the basis for determining the standard adsorption saturation condition, and can better reflect the comprehensive effect of the adsorption process than a single indicator (such as only considering the slope or time); by setting a reasonable first standard slope and standard time as thresholds, it can ensure that the pouring is stopped when the adsorption process has indeed reached the saturation state; avoiding insufficient adsorption due to premature stopping, or inaccurate measurement due to late stopping.
[0120] Specifically, the process of weighing the detection container and determining the actual continuous adsorption amount of the adsorbent according to the weighing result in this embodiment includes:
[0121] Step S710, weighing the detection container when pouring is stopped to obtain the actual weight;
