[0055] An automatic rubber tree tapping monitoring method, comprising the following steps:

[0056] S1, the box body 1 is fixed on the trunk of the rubber tree through the clamping assembly, and the rubber tree is cut to form a rubber mark, and the flow guide groove is inserted at the bottom end of the rubber mark, and the bottom end of the flow guide groove is located directly above the rubber collecting bowl 18;

[0057] S2, the formation and dripping process of the latex droplet in the rubber tree tapping process are dynamically monitored through the monitoring assembly, and the image / video data is transmitted to the external controller;

[0058] S3, the monitoring data transmitted by the monitoring assembly is recorded by the external controller, and then the formation time of a single latex droplet, the tapping time of a single tapping, the total tapping amount of a single tapping, and the length and diameter of the latex droplet are calculated by the external controller.

[0059] Further optimization scheme, in step S3, the formation time of a single latex droplet is calculated by the following formula:

[0060] t n = t n始 -t n止

[0061] Wherein, t n is the dripping time of the n-th latex, t n始 is the initial time of the dripping of the n-th latex droplet, and t n止 is the time when the n-th latex droplet is broken and the dripping is terminated.

[0062] Specifically, referring to Figure 4 , the initial time of the dripping of the latex droplet is set as the time when the latex droplet starts to form, and the time when the latex droplet is broken is set as the termination time of the dripping of the latex droplet.

[0063] Further optimizing the scheme, in step S3, the formula for calculating the glue removal time for a single tapping is:

[0064] t f =t n止 -t 1止

[0065] Among them, t f t represents the time for rubber discharge during a single tapping operation. 1止 t is the time it takes for the first drop of latex to fall. n止 This refers to the moment when the last drop of latex falls.

[0066] To further optimize the scheme, in step S3, the calculation steps for the total amount of rubber discharged in a single tapping are as follows:

[0067] S31. Calculate the sum of the volumes of all latex droplets;

[0068] S32. Multiply the sum of the volumes of the latex droplets by the density of the latex;

[0069] S33. Calculate the total amount of rubber discharged in a single tapping.

[0070] Reference Figure 7 The method for calculating the size of latex droplets is as follows: Extract the region of interest (ROI) of a single complete latex droplet to obtain an image of the single complete latex droplet, and calculate the pixel ratio of the latex droplet in the image to calculate its size.

[0071] The size (pixel percentage) and total number of all droplets in a single tapping process of a rubber tree are sequentially identified and calculated. Then, the average droplet size (pixel percentage) in a single tapping is calculated, and a functional relationship between the average droplet size (pixel percentage) and the actual average droplet volume is established. Based on the average droplet size (pixel percentage), the latex droplet volume can be predicted, and the total volume of latex discharged in a single tapping can be calculated. Multiplying this volume by the latex density gives the latex yield of a single tapping of the rubber tree.

[0072] Further optimizing the scheme, in step S3, the calculation method for the latex droplet length and diameter is as follows:

[0073] S34. First, extract the contour of one side of the wire drawing image and the coordinates of each point on the contour curve, and sort them in the y-axis direction;

[0074] S35. Solve for the upper and lower limits of the derivatives of the coordinate points of the contour curve. After removing the absolute value, find the two points with the largest difference. The point with the larger Y value is the highest point of the latex droplet forming a string, and the point with the smaller Y value is the lowest point of the latex droplet forming a string.

[0075] S36. Calculate the length and diameter of the latex droplet based on the coordinates of the highest and lowest points of the latex droplet.

[0076] Specifically, refer to Figures 5-6 First, the region of interest (ROI) is extracted from the image acquired by the camera to obtain image data of latex droplet stretching. Ignoring environmental disturbances, the latex droplet stretching image exhibits left-right symmetry. To determine the position of the highest point of the latex droplet stretching... Figure 6 Point a) and the location of the lowest point (as shown) Figure 6 As shown at point b), we first use image recognition technology to extract the contour of one side of the wire drawing image and the coordinates (x, y, y) of each point on the contour curve. i y i And sort them along the y-axis, then solve for the upper and lower limits of the derivatives of the coordinate points of the contour curve:

[0077] Formula for solving the upper limit:

[0078]

[0079] Δx=|x i-1 -x i |

[0080] Formula for solving the lower limit:

[0081]

[0082] Δx=|x i+1 -x i |

[0083] For each point in the coordinate system, calculate the upper and lower limits, then take the absolute value. Find the two points with the largest difference in absolute value; the point with the larger y-value is the highest point. Figure 6 Point a (as shown), the point with the smaller y-value is the lowest point. Figure 6 Point b shown)

[0084] The upper limit corresponds to the highest point of the latex droplet forming a string. Figure 6 Point a shown), the lower limit corresponds to the lowest point of the latex droplet forming a string (as shown in the figure). Figure 6 If we consider point b as an example, then the perpendicular distance between point a and point b is the wire length, calculated using the following formula:

[0085] L s =y a -y b

[0086] The midpoint between point a and point b ( Figure 6The width of the c point and the d point shown is the diameter of the latex droplet fiber drawing, and the calculation formula is as follows:

[0087] D s = x d -x c

[0088] Similarly, according to the above method, the fiber drawing length and fiber drawing diameter values at different times in the latex droplet fiber drawing formation process can be calculated, and the time function between the fiber drawing length and the fiber drawing diameter and the time t is established respectively, so as to dynamically monitor and analyze the formation process of the latex droplet fiber drawing. The dynamic changes of the latex droplet fiber drawing length and the fiber drawing diameter are closely related to the latex components, which are important characteristics reflecting the viscoelastic properties and rheological properties of the latex, and are also important potential indicators for evaluating the quality of the latex.

[0089] Example 2

[0090] Reference Figure 8 The difference between this embodiment and example 1 is that the latex droplet size calculation method in this embodiment is as follows: in the case of ignoring environmental disturbance, the latex droplet presents a regular shape of left-right symmetry, and it can be considered that the geometric body of the latex droplet is formed by rotating a curved surface around the central axis of the vertical direction of the droplet. Therefore, after obtaining the image data of a single complete latex droplet by ROI region extraction, taking the vertex of the two-dimensional cross section of the droplet in the vertical direction as the origin, an xoy plane coordinate system is established, and the coordinates of the latex droplet cross section are x∈[a, b] y∈[c, d]. By finding several coordinate points (note: due to the particularity of the droplet, the selected coordinate points x, y cannot be repeated), the corresponding curve equation can be obtained by fitting:

[0091] y = f(x)

[0092] In the spatial coordinate system, it can be written as follows: f(x, y) = 0

[0093] Ignoring the deformation caused by environmental disturbance, we can consider that the droplet is formed by rotating the above curve around the y-axis. From y = f(x), we can deduce: Then the area formula of the rotating surface is:

[0094]

[0095] The area of the rotating surface is the surface area of the latex droplet. Further, the volume formula of the rotating surface can be used to calculate the volume of the latex droplet, and the formula is as follows:

[0096]

[0097] The method for calculating the single tapping yield of rubber tree using the surface area of the latex droplet is as follows: identify and calculate the surface area S of all the droplets in the whole tapping process of the single tapping of the rubber tree in turni Given the total number of droplets n, calculate the average droplet surface area per tap. Establish the average droplet surface area and the true average droplet volume Functional relationship: Therefore, the volume of latex droplets can be predicted based on the average droplet surface area, and then the total volume of latex discharged in a single tap can be calculated. Multiplying this by the latex density gives the latex yield of a single tap of a rubber tree.

[0098] Furthermore, the area of ​​the cross-section (vertical profile) of the latex droplet, which is also the area of ​​the xoy plane, is calculated using the following formula:

[0099]

[0100] The method for calculating the yield of a single tap using the cross-sectional area of ​​latex droplets is as follows: Identify and calculate the cross-sectional area S′ of all droplets during the entire latex discharge process of a single tap on a rubber tree. i Given the total number of droplets n, calculate the average droplet cross-sectional area per single rubber tapping operation. Establish the functional relationship between the average droplet cross-sectional area and the true average droplet volume: Therefore, the volume of latex droplets can be predicted based on the average droplet cross-sectional area, and then the total volume of latex discharged in a single tap can be calculated. Multiplying this by the latex density will give the latex yield of a single tap of a rubber tree.

[0101] For latex droplets, surface area and volume reflect droplet size. Droplet size is related to droplet surface tension, which in turn is related to droplet composition. Latex composition is an important determinant of latex quality. Therefore, monitoring the differences or changes in the surface area and volume of latex droplets is beneficial for studying the formation and change patterns of rubber tree latex quality.

[0102] Example 3

[0103] In this embodiment, the method for calculating the yield of a single tapping operation using latex droplet volume is as follows: Samples are identified and the volume of sample droplets is calculated throughout the entire latex discharge process of the rubber tree, and the average droplet volume is calculated accordingly. Multiplying this by the total number of latex droplets (n) in a single tapping operation yields the total volume of latex discharged in that single tapping operation. The latex yield per tap of a rubber tree can be obtained by multiplying the total volume of latex by the latex density.

[0104] Example 4

[0105] In this embodiment, the method for calculating the yield of a single tap using latex droplet volume is as follows: The sum of the volumes of all droplets during the entire latex discharge process of a single tap is identified and calculated sequentially; this is the total volume of latex discharged in a single tap. Multiplying by the latex density gives the latex yield of a single tapping of a rubber tree.
