Description

Technical Field

[0001] The present invention relates to the technical field of component measurement, and in particular to a water source sampling, detection and analysis method and device used in animal husbandry. Background Art

[0002] Animal husbandry refers to the agricultural practice of raising livestock, poultry, and other animals to produce meat, milk, eggs, fur, and other by-products. Water is a crucial resource for animal husbandry, as livestock require it for survival. Water contains a large number of dissolved nutrients, which are essential for livestock's metabolic activities and digestion. However, chemicals and antibiotics used in animal husbandry can also contaminate water sources, impacting water safety. Therefore, regular water sampling and testing is necessary. Animal husbandry often involves free-range, outdoor farming. During actual water sampling and testing, impurities can interfere with the water source, clogging the sampling tube and impacting the required sampling and testing.

[0003] In some scenarios, in order to prevent debris from clogging the sampling tube during sampling, a motor is often used to drive multiple stirring rods around the nozzle of the sampling tube to pre-stir, dispersing impurities near the nozzle of the sampling tube to prevent debris from entering the sampling tube during the sampling process. However, using this method, the rotation of the motor will cause water disturbances, which will cause bottom sediments to float up. The disturbance of the lever during sampling by the water source detection equipment will also cause water sediments to suspend, affecting the accuracy of water source sampling and detection. In this way, the above method will result in a large error between the detection results of water source sampling and detection and the actual water source conditions, and the accuracy of the detection results of water source sampling and detection is low.

[0021] To further illustrate the technical means and effectiveness of the present invention in achieving its intended purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, describes in detail a method and apparatus for sampling, detecting, and analyzing water sources for livestock farming, including its specific implementation, structure, features, and effectiveness. In the following description, references to different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.

[0022] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0023] The following describes in detail a specific scheme of a water source sampling, detection and analysis method for animal husbandry provided by the present invention with reference to the accompanying drawings.

[0024] Example 1:

[0025] See also Figure 1 , which shows a flow chart of a water source sampling, detection and analysis method applied to animal husbandry provided by one embodiment of the present invention, including:

[0026] Step S101 , obtaining the livestock breeding density in the breeding area, the depth of the water source in the breeding area, and the relative elevation of the water body at the location of the sampling point in the water source.

[0027] Specifically, during the livestock breeding process, livestock activities, such as the infiltration of nitrogen and phosphorus in their excrement into the water, can impact the water source environment of the breeding area. Therefore, it is necessary to conduct necessary sampling and testing of the water source in the breeding area. In order to make the test results of the sampled water more accurate during the sampling process of the livestock breeding area, the embodiment of the present invention needs to analyze the scene characteristics of the sampling point. Therefore, the embodiment of the present invention collects information such as the livestock breeding density in the breeding area, the depth of each water body in the water source, the relative elevation of each water body, and the slope of the water body.

[0028] The livestock breeding density of a breeding area can be the ratio of the total number of livestock within the breeding area to the total area of the breeding area. The relative elevation of the water body at the sampling point within the water source refers to the elevation difference between the lowest point of the water body within the breeding area and the lowest point of the water source. Furthermore, the water body refers to the water in pools and ponds within the water source.

[0029] Step S102: determining the initial rotation speed of the water quality sampler according to the livestock breeding density and the adjustment parameters.

[0030] Specifically, the different depths of different water bodies result in differences in the concentrations of nitrogen and phosphorus sediments in the water during sampling. The different sediment concentration differences will interfere with the detection results of the collected samples due to the disturbance of the water body on the sediments when the water quality sampler is sampling, thereby affecting the accuracy of the inspection results. Therefore, the embodiment of the present invention analyzes the degree of interference with the nitrogen and phosphorus sediments at the bottom of the water body at different sampling depths, and adaptively adjusts the rotation speed of the rotating rod according to the location of the sampling point, so that when it performs water source sampling, it can ensure the sampling efficiency and reduce the interference of the floating bottom sediments on the detection results.

[0031] Furthermore, when the livestock density in the breeding area is greater, the pollution to the water source is more serious, and the water body contains more debris, such as floating objects, debris, aquatic plants, feces, etc., so when sampling the water body, in order to avoid debris blocking the water inlet, the rotation speed needs to be set higher. Therefore, a certain initial rotation speed is set according to the livestock breeding density in the breeding area. As an optional embodiment of the present invention, determining the initial rotation speed of the water quality sampler according to the livestock breeding density and the adjustment parameter includes: determining the first product between the livestock breeding density and the adjustment parameter as the initial rotation speed of the water quality sampler.

[0032] Specifically, the embodiment of the present invention uses the following formula to calculate the initial rotation speed of the water quality sampler:

[0033]

[0034] In the above formula, Indicates the initial rotation speed of the water quality sampler in the aquaculture area. Indicates the livestock breeding density in the breeding area. Represents an adjustment parameter. The greater the livestock density in a breeding area, the greater the degree of water pollution caused by livestock activities, and the more debris is present in the water. Therefore, the rotation speed of the water sampler's rotating rod should be increased so that the rotation of the water sampler's rotating rod can remove the debris around the water sampler.

[0035] Step S103 , determining the diffusion coefficient of nitrogen and phosphorus sediments in the water body according to the relative elevation of the water body at the sampling point, the slope of the water body, and the sampling depth of the water quality sampler.

[0036] Specifically, when sampling water through a water quality sampler, the lower the relative elevation of the water body at the sampling point, the more nitrogen and phosphorus sediments will be at the bottom of the water body in the aquaculture area at lower altitudes through the convergence of surface flow and groundwater. When sampling water quality, the water quality sampler rotates the water body to push away the suspended debris in the water body. The rotation of the rotating rod causes a vortex in the steady-state water body, which will cause the nitrogen and phosphorus sediments at the bottom of the water body to be suspended, thereby making the sampled water body detection results inaccurate. However, the rotation energy of the rotating rod is limited, that is, the disturbance to the water body is limited, and the water body itself has a certain viscosity, which has a certain weakening effect on the downward transmission of the vortex. Therefore, when the depth of the water body where the sampling point is located is deeper, the influence of nitrogen and phosphorus sediments in the water body at the sampling point is smaller. Therefore, the embodiment of the present invention calculates the water body position influence parameter of the sampling point based on this. Moreover, the edge of the water body in the natural state presents a trapezoidal edge feature, which makes the distribution of nitrogen and phosphorus in the sediment show a trend that the lower layer is higher than the upper layer. Water bodies in the natural state, such as ponds and lakes, have a certain stratification barrier under stable conditions. When the water body is disturbed by the rotation of the water quality sampler, the stratification barrier of the water body is affected, and the high-concentration nitrogen and phosphorus sediments at the bottom of the water body release a large amount of suspended matter. The nitrogen and phosphorus concentrations in the water body diffuse from high concentration to low concentration, that is, the nitrogen and phosphorus sediments spread upward from the bottom of the water body. However, in the water body of the breeding area, due to the activities of livestock, such as excrement, etc., they are merged into the water body with rainwater and surface runoff. Since the temperature of the upper layer of the water body is higher, there are more nitrogen and phosphorus elements dissolved in the upper water body, while the lower water body has a lower content of dissolved nitrogen and phosphorus because of the lower temperature. Similarly, due to the disturbance of the water body, the nitrogen and phosphorus elements in the high-concentration water body on its surface will also diffuse downward. Therefore, the diffusion interference of the bottom nitrogen and phosphorus sediments during collection should be avoided. Therefore, the embodiment of the present invention also calculates the diffusion coefficient of the nitrogen and phosphorus sediments.

[0037] Furthermore, the edge of the water body in the natural state presents a trapezoidal edge feature, so the water body has a certain slope, for example, Figure 2 As shown, Figure 2 A schematic diagram of a water body edge provided by an embodiment of the present invention, Figure 2 In the figure, the depth of the water body is h, and the sampling depth of the water sampler is Therefore, the diffusion coefficients of nitrogen and phosphorus in the water body can be determined based on the relative elevation of the water body at the sampling point, the slope of the water body, and the sampling depth of the water quality sampler.

[0038] Furthermore, as an optional embodiment of the present invention, determining the diffusion coefficient of nitrogen and phosphorus sediments in the water body according to the relative elevation of the water body at the sampling point, the slope of the water body, and the sampling water depth of the water quality sampler includes: calculating the relative concentration index of the water body according to the relative elevation of the water body at the sampling point; determining the water body position influence parameter of the water body at the sampling point using the relative concentration index of the water body and the depth of the water body at the sampling point; determining the diffusion coefficient of nitrogen and phosphorus sediments in the water body according to the water body position influence parameter, the slope of the water body, and the sampling water depth of the water quality sampler.

[0039] Specifically, the embodiment of the present invention calculates the relative concentration index of nitrogen and phosphorus precipitation in the water body through the relative elevation of the water body in the aquaculture area. As an optional embodiment of the present invention, the relative concentration index of the water body is calculated according to the relative elevation of the water body at the sampling point, including: performing inverse proportional normalization processing on the relative elevation of the water body at the sampling point to obtain the relative concentration index of the water body.

[0040] Specifically, the embodiment of the present invention uses the following formula to calculate the relative concentration index of the water body:

[0041]

[0042] In the above formula, Represents the relative concentration index in the water body z within the aquaculture area. It represents the relative elevation of the water body z in the aquaculture area. The lower the relative elevation of the water body at the sampling point, the greater the relative concentration index in the water body. Represents the inverse normalization function, which is used to Perform inverse proportional normalization.

[0043] Furthermore, the water position influence parameter of the sampling point is calculated based on the depth of the water body at which the sampling point is located. This is because the greater the depth of the water body, the stronger the effect of the viscosity of the water on weakening the vortex, and the smaller its effect on the nitrogen and phosphorus sediments at the bottom of the water, that is, the smaller the water position influence parameter of the sampling point. Moreover, because the water body is disturbed, the greater the concentration of sediment at the bottom of the water body, the greater its sensitivity to water body disturbance. Therefore, the water position influence parameter of the sampling point is calculated using the relative concentration index in the water body as a weight. As an optional embodiment of the present invention, determining the water position influence parameter of the water body at the location of the sampling point using the relative concentration index of the water body and the depth of the water body at the location of the sampling point includes: calculating a first ratio between the relative concentration index and the depth of the water body at the location of the sampling point; and normalizing the first ratio using a proportional normalization function to obtain the water position influence parameter.

[0044] Specifically, the embodiment of the present invention uses the following formula to calculate the water body position influence parameter:

[0045]

[0046] In the above formula, Represents the water body position influence parameter of the water body z where the sampling point is located. represents the depth of water body z, Represents the relative concentration index in water body z. The smaller the water depth in water body z, the larger the relative concentration index in the water, indicating that the location of the sampling point in water body z has a greater impact on the parameter. Represents a proportional normalization function, which is used to It should be noted that in order to ensure that the calculation results are meaningful, when performing fractional operations in the embodiment of the present invention, when encountering a situation where the denominator is 0, it is necessary to add a parameter adjustment factor greater than 0 to the denominator to prevent the denominator from being 0. The value of the parameter adjustment factor is set by the implementer according to the actual situation, and this application does not impose any special restrictions.

[0047] Furthermore, as an optional embodiment of the present invention, determining the diffusion coefficient of nitrogen and phosphorus sediments in the water body based on the water body position influencing parameter, the slope of the water body and the sampling water depth of the water quality sampler includes: calculating the second ratio between the water body position influencing parameter and the slope of the water body, and the second product between the second ratio and the sampling water depth; normalizing the second product using a proportional normalization function to obtain the diffusion coefficient.

[0048] Specifically, the embodiment of the present invention obtains the slope of the water body z, that is, , and then obtain the sampling depth of the water quality sampler in the water body z The diffusion coefficient is then calculated using the following formula:

[0049]

[0050] In the above formula, Indicates the water body z at the sampling depth Diffusion coefficients of nitrogen and phosphorus deposits at . Represents the water position influence parameter of water body z. Indicates the slope of the water body z. Indicates the sampling depth of the water quality sampler in the water body z.

[0051] Among them, when the water body slope of water body z is smaller, the water body position influence parameter is larger, which means that the water body is more susceptible to interference from bottom nitrogen and phosphorus sediments when taking water, that is, its influence on the diffusion of nitrogen and phosphorus sediments is greater. The ratio of is taken as the weight of its diffusion coefficient. When the position where the sampler collects water samples is closer to the bottom of the water body, that is, the sampling depth The larger the diffusion coefficient The larger the value, the greater the diffusion coefficient of nitrogen and phosphorus sediments.

[0052] Step S104 , using the diffusion coefficient of nitrogen and phosphorus sediments in the current water body and the diffusion coefficient of nitrogen and phosphorus sediments in other water bodies at the same sampling depth, determines the diffusion difference of nitrogen and phosphorus sediments in the current water body.

[0053] Specifically, when sampling and testing water pollutants, vertical lines are set when setting sampling points for the same water body, that is, sampling is performed at different depths at the same location in the water body. When the rotation speed is too low, it is unable to effectively remove debris from the water, which can easily lead to clogging of the water quality collector's water inlet. When the rotation speed is too high, it may cause a large amount of bottom sediment to be suspended, thereby affecting the accuracy of the test results. Therefore, when sampling at different depths in the same water body, it is necessary to set different adjustment rod speeds based on the diffusion degree of nitrogen and phosphorus sediments. Because the deeper the sampling depth of the water quality sampler, the greater the water pressure it is subjected to, and the temperature drops, the less nitrogen and phosphorus dissolved in the water, that is, the lower the concentration of nitrogen and phosphorus content at the sampling point. The greater the degree of influence of nitrogen and phosphorus sediments at the bottom of the water body, the diffusion degree of nitrogen and phosphorus sediments at the sampling point is calculated, and the rotation speed of the water quality sampler is adaptively adjusted.

[0054] Furthermore, as an optional embodiment of the present invention, the diffusion coefficient of nitrogen and phosphorus sediments in the current water body and the diffusion coefficient of nitrogen and phosphorus sediments in other water bodies at the same sampling water depth are used to determine the diffusion difference of nitrogen and phosphorus sediments in the current water body, including: calculating the first difference between the diffusion coefficient of nitrogen and phosphorus sediments in the current water body and the diffusion coefficient of nitrogen and phosphorus sediments in other water bodies, and superimposing each first difference to obtain a first superimposed value; and normalizing the first superimposed value using a proportional normalization function to obtain the diffusion difference.

[0055] Specifically, the embodiment of the present invention uses the following formula to calculate the diffusion difference:

[0056]

[0057] In the above formula, Indicates the sampling water depth is Differences in the diffusion of nitrogen and phosphorus sediments in the lower water column z. Indicates the sampling water depth is Diffusion coefficients of nitrogen and phosphorus in sediments of water body z within the aquaculture area. Indicates the sampling water depth is The diffusion coefficient of nitrogen and phosphorus sediments in the remaining water bodies x in the aquaculture area. X represents the number of water bodies in the aquaculture area. Represents a proportional normalization function, which is used to Perform normalization processing.

[0058] in, It indicates the difference in the diffusion coefficient of nitrogen and phosphorus sediments in the bottom of water body z at the same sampling depth. The larger the value, the deeper the water body z is at the sampling depth. The greater the diffusion difference of nitrogen and phosphorus sediments, that is, the easier it is for nitrogen and phosphorus sediments at the bottom of the water body z to diffuse, the smaller the rotating rod speed of the water quality sampler should be.

[0059] Step S105 , determining a bottom impact distance difference index of the current water body according to the first depth of the current water body, the sampling depth of the current water body, the second depth of other water bodies, and the sampling depth of other water bodies.

[0060] Specifically, because the water depths of different water bodies are different, at the same sampling depth, the depth of the water body is at different distances from the sampling point. The closer the depth of the water body is to the sampling point, the greater the interference it has on the bottom nitrogen and phosphorus sediments. Based on this, the bottom impact distance difference index is calculated in this embodiment of the present invention.

[0061] Furthermore, as an optional embodiment of the present invention, determining the bottom layer impact distance difference index of the current water body based on the first depth of the current water body, the sampling water depth of the current water body, the second depth of other water bodies and the sampling water depth of other water bodies includes: calculating the second difference between the first depth of the current water body and the sampling water depth of the current water body, and the third difference between the second depth of other water bodies and the sampling water depth of other water bodies; calculating the fourth difference between the second difference and the third difference, and superimposing the fourth difference to obtain a second superimposed value; performing inverse proportional normalization processing on the second superimposed value to obtain the bottom layer impact distance difference index of the current water body.

[0062] Specifically, the embodiment of the present invention uses the following formula to calculate the bottom impact distance difference index of the current water body:

[0063]

[0064] In the above formula, Indicates that the water body z is at a sampling depth of The bottom-level influence distance difference index when . Indicates the first depth of the water body z. Indicates the sampling depth of water body z. Indicates the second depth of other water body x. represents the sampling depth of other water bodies x. X represents the number of water bodies in the aquaculture area. Represents the inverse normalization function, which is used to Perform inverse proportional normalization.

[0065] Step S106, based on the current diffusion difference of the water body, the bottom impact distance difference index and the initial rotation speed, the final rotation speed of the water quality sampler is determined, and the water quality sampler is controlled to sample and detect the water source at the final rotation speed.

[0066] Specifically, the embodiment of the present invention is based on the sampling depth of the sampling point of the water body z. The rotation speed of the water quality sampler is adjusted based on the diffusion difference of bottom nitrogen and phosphorus sediments and the bottom impact distance difference index.

[0067] Furthermore, as an optional embodiment of the present invention, based on the diffusion difference of the current water body, the bottom layer influence distance difference index and the initial rotational speed, determining the final rotational speed of the water quality sampler includes: calculating the third product between the diffusion difference of the current water body and the bottom layer influence distance difference index, and normalizing the inverse of the third product using a proportional normalization function to obtain a normalized value; calculating the first sum between the normalized value and the predetermined value; and determining the fourth product between the first sum and the initial rotational speed as the final rotational speed of the water quality sampler.

[0068] Specifically, the predetermined value is 0.5 in the embodiment of the present invention. The embodiment of the present invention specifically uses the following formula to calculate the final rotation speed of the water quality sampler:

[0069]

[0070] In the above formula, Indicates that the water body z is at a sampling depth of The final rotation speed of the rotating rod of the water quality sampler at this time. Indicates that the water body z is at a sampling depth of The bottom-level influence distance difference index when . Indicates the sampling water depth is Differences in the diffusion of nitrogen and phosphorus sediments in the lower water column z. Indicates the initial speed. Represents a proportional normalization function, which is used to Perform normalization processing.

[0071] Among them, when the sampling depth in the water body z is When the diffusion difference of nitrogen and phosphorus sediments at the location is greater, the greater the difference index of the bottom influence distance of the water body is, which indicates that the depth of the sampling point is more likely to be affected by the bottom nitrogen and phosphorus sediments when sampling. Therefore, the embodiment of the present invention uses its The product of is the weight. When the product is larger, it means that it is more likely to be affected by interference, then the speed of the rotating rod of the sampling water device should be smaller. So take the inverse of the product and normalize it. When it has a greater impact on the bottom nitrogen and phosphorus sediments, The smaller it is, if the parameter 0.5 is added and the sum is less than 1, the initial rotation speed is suppressed, so that the final rotation speed of the rotating rod is reduced. On the contrary, if its effect is small and the final sum is greater than 1, it indicates that its impact on the sampling point is small. In order to improve the sampling efficiency, the rotation speed of the rotating rod of the sampling water collector can be increased.

[0072] Furthermore, the present invention adaptively adjusts the rotation speed of the sampling and water extraction rod. After collecting water samples from the target water body in the breeding area, the samples are then packaged and labeled in dedicated packaging containers to avoid contamination and confusion before being sent to the laboratory for testing. Because livestock activities in breeding areas, such as excretion, can increase the nitrogen and phosphorus content in the breeding area, the nitrogen and phosphorus content in the water can be measured to determine the extent of livestock activities on the water body, thereby conducting water source pollution assessments.

[0073] The embodiment of the present invention preliminarily sets the initial rotation speed according to the breeding density of the breeding area in the livestock area, then determines the diffusion coefficient of the nitrogen and phosphorus sediments in the water body according to the location of the water body, and finally calculates the diffusion difference and the bottom impact distance difference index between the water bodies based on the sampling water depth of the sampling point, the slope characteristics of the water body and the depth of the water body. According to the diffusion difference, the bottom impact distance difference index and the initial rotation speed, the final rotation speed of the water quality sampler is determined. Therefore, the embodiment of the present invention adaptively adjusts the rotation speed of the water quality sampler according to the location of the water body where the sampling point is located, so that when it performs water source sampling, it can not only ensure the sampling efficiency but also reduce the interference of the floating of the bottom sediment on the detection result. It reduces the error between the detection result of the water source sampling detection and the actual water source situation, and improves the accuracy of the detection result of the water source sampling detection.
