[0002] Selenium is a trace element that is essential to human health. It has multiple physiological functions such as regulating immunity, anti-oxidation, protecting cell membranes and promoting the development of the immune system. In plants, selenium also plays an important role, participating in regulating chlorophyll synthesis, photosynthesis, promoting vitamin E synthesis and the activity of antioxidant enzymes. Therefore, the sufficiency of selenium directly affects the growth and quality of highland barley. Highland barley is a crop with strong adaptability, cold resistance and drought resistance. It is mainly produced in the high-altitude cold areas in western my country, especially in the Qinghai-Tibet Plateau. The growth of highland barley requires suitable climate, soil and light conditions. Among them, the selenium content in the soil has an important influence on the growth and quality of highland barley. Selenium has a significant effect on the growth and quality of highland barley. First, selenium can improve the antioxidant and stress resistance of highland barley and enhance its adaptability to adversity. Secondly, selenium also has a certain promoting effect on the yield and quality of highland barley, and can increase the selenium content and nutritional value in highland barley grains. However, the effect of selenium on highland barley is still restricted by many factors, such as the type of selenium fertilizer, application period, highland barley variety, etc.

[0028] The embodiment of the present application solves the problem of low accuracy of selenium data in monitoring the highland barley growth environment in the prior art by providing a selenium monitoring and control system and device for the highland barley growth environment. The system obtains reaction rate data, diffusion rate data and dissolution rate data, and then combines the reaction rate data with reference reaction rate data obtained from a preset database to obtain a reaction rate evaluation index. The reaction rate evaluation index, diffusion rate data and reference diffusion rate data obtained from the preset database are then combined to obtain a diffusion rate evaluation index. Finally, the diffusion rate evaluation index, dissolution rate data and reference dissolution rate data obtained from the preset database are combined to obtain a dissolution rate evaluation index, thereby achieving more accurate monitoring and control of selenium in the highland barley growth environment.

[0029] The technical solution in the embodiment of the present application is to solve the problem of low accuracy of the selenium element data in the above-mentioned monitoring of the highland barley growth environment. The overall idea is as follows:

[0030] The reaction rate evaluation index is obtained by combining the highland barley grain monitoring data with the reference reaction rate data.

Finally, the dissolution rate evaluation index is obtained by combining the diffusion rate evaluation index, the highland barley grain monitoring data and the reference dissolution rate data. This achieves the effect of more accurate monitoring and regulation of the selenium element in the highland barley growth environment.

[0031] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] like Figure 1As shown, it is a structural schematic diagram of a selenium monitoring and control system for a highland barley growth environment provided by an embodiment of the present application, including a highland barley grain monitoring data acquisition module, a reaction rate evaluation index acquisition module, a diffusion rate evaluation index acquisition module, a dissolution rate evaluation index acquisition module and a soil monitoring module: wherein the highland barley grain monitoring data acquisition module is used to monitor the highland barley grain extraction process through a preset monitoring device to obtain highland barley grain monitoring data, and the extraction is used to improve the solubility of the highland barley grain sample in an acidic solution, and the highland barley grain monitoring data includes reaction rate data, diffusion rate data and dissolution rate data; the reaction rate evaluation index acquisition module is used to combine the reaction rate data with the reference reaction rate data obtained from a preset database to obtain a reaction rate evaluation index, and to determine whether to adjust the reaction rate in combination with a preset reaction rate influence threshold value, and the reaction rate adjustment is used to adjust the reaction rate evaluation index to not less than the preset reaction rate influence threshold value, and the reaction rate evaluation index is used to evaluate the influence of the reaction rate of highland barley grains on the release of selenium during the highland barley grain extraction process; the diffusion rate evaluation index acquisition module is used to obtain the reaction rate evaluation index of the highland barley grains. The reaction rate evaluation index, diffusion rate data and reference diffusion rate data obtained from a preset database are combined to obtain a diffusion rate evaluation index, and a preset diffusion rate influence threshold is combined to determine whether to adjust the diffusion rate. The diffusion rate adjustment is used to adjust the diffusion rate evaluation index to no less than the preset diffusion rate influence threshold. The diffusion rate evaluation index is used to evaluate the influence of the diffusion rate of highland barley grains on the release of selenium during the extraction of highland barley grains; the dissolution rate evaluation index acquisition module is used to combine the diffusion rate evaluation index, dissolution rate data and reference dissolution rate data obtained from a preset database to obtain a dissolution rate evaluation index, and a preset dissolution rate influence threshold is combined to determine whether to adjust the dissolution rate. The dissolution rate adjustment is used to adjust the dissolution rate evaluation index to no less than the preset dissolution rate influence threshold. The dissolution rate evaluation index is used to evaluate the influence of the dissolution rate of highland barley grains on the release of selenium during the extraction of highland barley grains; the soil monitoring module is used to monitor the selenium release capacity of highland barley grains according to the obtained reaction rate evaluation index, diffusion rate evaluation index and dissolution rate evaluation index.

[0033] In the present embodiment, the acidic solution includes hydrochloric acid and acetic acid, etc. The hydrogen ions in the acidic solution may participate in the degradation of the cell wall components of highland barley grains, thereby destroying the cell wall structure, making the components in the cell more easily released, and then improving solubility. The reaction rate evaluation index, the diffusion rate evaluation index and the dissolution rate evaluation index are interrelated and mutually influenced in the highland barley grain extraction process. In the highland barley grain extraction process, the acceleration of the reaction rate usually means that the breaking of chemical bonds is accelerated, and more soluble substances are generated, thereby promoting the diffusion of these substances in the solvent. The improvement of the reaction rate can often drive the increase of the diffusion rate, so that the reaction product is distributed to the whole solution faster. The speed of diffusion rate directly affects the contact frequency between solute molecules and solvent molecules, thus determining the dissolution rate. The dissolution rate evaluation index usually increases with the increase of the diffusion rate evaluation index. The reaction rate evaluation index, diffusion rate evaluation index and dissolution rate evaluation index are monitored. When the reaction rate evaluation index is not lower than the preset reaction rate impact threshold, the diffusion rate evaluation index is not lower than the preset diffusion rate impact threshold, and the dissolution rate evaluation index is not lower than the preset dissolution rate impact threshold, it means that the release of selenium in the extraction process of highland barley grains is strong, which indirectly reflects the high selenium content in highland barley grains. By monitoring the release capacity during the extraction process of selenium, it indirectly reflects the accumulation of selenium in the soil, which is beneficial to the accumulation of selenium in highland barley and promotes selenium enrichment during its growth process. The accumulation of selenium in highland barley is directly affected. Taking into account the influence of multiple factors such as selenium content in the soil, morphological distribution, soil physical and chemical properties, and highland barley variety specificity, when the reaction rate evaluation index is lower than the preset reaction rate impact threshold, the diffusion rate evaluation index is lower than the preset diffusion rate impact threshold, and the dissolution rate evaluation index is lower than the preset dissolution rate impact threshold, the pH value of the highland barley growth environment is adjusted and the soil organic matter is increased to improve the absorption capacity of the highland barley root system for selenium, ensuring that the highland barley obtains an appropriate amount of selenium during the growth process, thereby ensuring the normal growth and yield of highland barley and providing high-quality raw materials for subsequent selenium extraction. Therefore, by extracting highland barley grains and monitoring their selenium release capacity, we can indirectly evaluate the biological effectiveness of selenium in the soil and its absorption and utilization by highland barley; achieving more accurate monitoring and regulation of selenium in the highland barley growth environment.

[0034] Furthermore, the reaction rate data include reaction activation energy, reaction temperature and reaction order, and the reaction rate data are used to describe the reaction rate of highland barley seeds during the extraction process of highland barley seeds; the diffusion rate data include diffusion activation energy, diffusion temperature and extraction concentration, and the diffusion rate data are used to describe the diffusion rate of highland barley seeds during the extraction process of highland barley seeds; the dissolution rate data include solute saturation concentration, contact area, solute concentration and dissolution time, and the dissolution rate data are used to describe the dissolution rate of highland barley seeds during the extraction process of highland barley seeds; the preset monitoring equipment includes a differential scanning calorimeter, a timer, a laser particle size analyzer, a UV-visible spectrophotometer and a temperature sensor.

[0035] In this embodiment, a differential scanning calorimeter is used to monitor the heat flow difference between highland barley seeds and a preset reference at a preset temperature, and heat flow data at different preset temperatures are recorded. The preset temperatures include 30 degrees Celsius, 35 degrees Celsius, 40 degrees Celsius, 45 degrees Celsius, 50 degrees Celsius, 55 degrees Celsius, and 60 degrees Celsius. The heat flow data is linearly fitted with the corresponding preset temperature, and the reaction activation energy is obtained according to the slope of the fitting line. The reaction temperature of the reaction system is recorded using a temperature sensor, and the change in the reaction rate is monitored by increasing or decreasing the reactant concentration step by step by a preset multiple. The reaction order is obtained by fitting the rate equation, and the concentration distribution data between highland barley seeds and the preset reference material is monitored at a preset temperature using a diffusion coefficient measuring instrument. The diffusion coefficient at different preset temperatures is obtained using the diffusion equation according to the concentration distribution data, and the diffusion coefficient is linearly fitted with the corresponding preset temperature. The diffusion activation energy is obtained according to the slope of the fitting line. In the process of measuring the diffusion coefficient, the diffusion temperature is recorded by a temperature sensor, and the concentration of the solute in the extract is detected at a preset time point by a UV-visible spectrophotometer. The diffusion rate is obtained by combining the time data and then the average value is taken. The solute concentration when saturation is reached is measured using a UV-visible spectrophotometer. The contact area with the solvent is obtained by using a laser particle size analyzer, and the concentration of the solute during the dissolution process is measured at a preset time point using a UV-visible spectrophotometer. The solute concentration measured at the preset time point is averaged, and the timer is used to record the time required from the start of dissolution to the preset equilibrium state. The preset equilibrium state represents the corresponding state when the solute concentration remains unchanged within the preset time period; more accurate monitoring and regulation of selenium in the highland barley growth environment is achieved.

[0036] Furthermore, the specific process of combining the reaction rate data with the reference reaction rate data obtained from the preset database to obtain the reaction rate evaluation index is as follows: combining the reference reaction rate data and the reaction rate data to obtain the reaction constant deviation and the reaction rate deviation, the reaction constant deviation is used to describe the degree of deviation between the reaction constant in the highland barley seed extraction process and the preset reaction constant threshold, and the reaction rate deviation is used to describe the degree of deviation between the reaction rate in the highland barley seed extraction process and the preset reaction rate threshold; judging whether the reaction constant deviation and the reaction rate deviation are not less than 0, when the reaction constant deviation and the reaction rate deviation are not less than 0, combining the preset first The reaction rate allocation weight and the preset second reaction rate allocation weight are used to obtain the reaction rate evaluation index, otherwise the reaction constant deviation and the reaction rate deviation are recorded as 0; the reference reaction rate data include a preset reaction constant threshold, a preset reaction rate threshold, a frequency factor, a gas constant, a preset first reaction rate allocation weight and a preset second reaction rate allocation weight. The preset first reaction rate allocation weight is used to evaluate the influence of the reaction constant deviation on the reaction rate evaluation index during the extraction process of highland barley grains, and the preset second reaction rate allocation weight is used to evaluate the influence of the reaction rate deviation on the reaction rate evaluation index during the extraction process of highland barley grains.

[0037] The limiting expression for the reaction rate evaluation index is as follows:

[0038]

[0039] In the formula, J s represents the reaction rate evaluation index of highland barley grains in the sth preset time period during the extraction process of highland barley grains, s=1,2,...,h, s represents the number of the preset time period, h represents the total number of preset time periods, A s represents the reaction constant deviation of highland barley grains in the sth preset time period during the highland barley grain extraction process, B s represents the reaction rate deviation of highland barley grains in the sth preset time period during the highland barley grain extraction process, E 1s represents the activation energy of highland barley grains in the sth preset time period during the extraction process of highland barley grains, T 1s represents the reaction temperature of highland barley grains in the sth preset time period during the highland barley grain extraction process, n s represents the reaction order of highland barley grains in the sth preset time period during the extraction process of highland barley grains, A0 represents the frequency factor, R0 represents the gas constant, V0 represents the preset reaction constant threshold, V1 represents the preset reaction rate threshold, α1 represents the preset first reaction rate allocation weight, α2 represents the preset second reaction rate allocation weight, and e represents the natural constant.

[0040] In this embodiment, the preset reaction constant threshold is represented by the average value of the reaction constant data in the historical period of highland barley grain extraction process in the preset database, the preset reaction rate threshold is represented by the average value of the reaction rate data in the historical period of highland barley grain extraction process in the preset database, the frequency factor is represented by the average value of the frequency factor data in the historical period of highland barley grain extraction process in the preset database, and the gas constant is usually taken as 8.314J / (mol*K); more accurate monitoring and control of selenium in the highland barley growth environment is achieved.

[0041] Specifically, the sum of the preset first reaction rate allocation weight and the preset second reaction rate allocation weight is 1, for example, the preset first reaction rate allocation weight is 0.4, and the preset second reaction rate allocation weight is 0.6; the preset second reaction rate allocation weight is the weight corresponding to the preset reaction rate value in the preset database, which represents the influence degree of the reaction rate value on the reaction rate evaluation index. When used, the weight corresponding to the preset reaction rate value can be directly obtained from the preset database, and the corresponding relationship can be a preset mapping relationship. For example, the reaction rate in the highland barley grain selenium extraction training set and the weight corresponding to the preset reaction rate value in the preset database form a mapping set, and the real-time reaction rate is input into the mapping set to obtain the corresponding weight, wherein the mapping relationship can be a one-to-one correspondence or a many-to-one relationship. In this example, its value range is [0, 1].

[0042] It should be understood that when the reaction constant deviation and the reaction rate deviation are not less than 0, the algorithm of this embodiment combines the reaction rate data for comprehensive analysis to obtain the reaction rate evaluation index. The reaction rate data in the algorithm of this embodiment do not exist independently, but are interrelated. The greater the activation energy, the higher the reaction rate evaluation index. The influence of the reaction temperature should also be considered comprehensively. When the reaction temperature is too high, it may cause decomposition of the reactants, deactivation of the catalyst, or intensification of side reactions, and the reaction rate evaluation index may decrease. The parameters of the algorithm of this embodiment need to consider their impact on the results together.

[0043] Specifically, assuming that the reaction constant deviation A s The range is 0-10, the reaction rate deviation B s The range is 0-10, the first reaction rate allocation weight is preset to 0.4, and the second reaction rate allocation weight is preset to 0.6. Figure 2 As shown, it is a statistical diagram of the change of the reaction rate evaluation index provided in the embodiment of the present application, which is Figure 2 It can be seen that when the reaction rate deviation B s When the reaction constant deviation A is 0, s The reaction rate evaluation index gradually decreases when the reaction constant deviation A s When the reaction rate deviation Bs As the reaction rate increases, the reaction rate evaluation index gradually decreases, achieving more accurate monitoring and regulation of selenium in the highland barley growth environment.

[0044] Furthermore, the specific process of judging whether to adjust the reaction rate in combination with the preset reaction rate influence threshold is as follows: Q1, judging whether the reaction rate evaluation index is not lower than the preset reaction rate influence threshold. When the reaction rate evaluation index is not lower than the preset reaction rate influence threshold, no reaction rate adjustment is performed, otherwise Q2 is executed; Q2, sending a prompt to the preset personnel to increase the concentration of the highland barley grain extract step by step by a preset multiple of the preset sodium nitrite concentration threshold. When the monitored reaction rate evaluation index is not lower than the preset reaction rate influence threshold, execution is stopped, otherwise Q3 is executed; Q3, sending a prompt to the preset personnel to reduce the pH of the highland barley grain extract step by step by a preset multiple of the preset pH threshold. When the monitored reaction rate evaluation index is not lower than the preset reaction rate influence threshold, execution is stopped, otherwise feedback is given to the preset personnel.

[0045] In this embodiment, the preset reaction rate influencing threshold is represented by the average value of the reaction rate influencing data during the extraction of highland barley grains in the historical period in the preset database, the preset sodium nitrite concentration threshold is represented by the average value of the sodium nitrite concentration data during the extraction of highland barley grains in the historical period in the preset database, and the preset pH threshold is represented by the average value of the pH data during the extraction of highland barley grains in the historical period in the preset database. By increasing the sodium nitrite concentration, the interaction between the solute and the solvent is increased, thereby accelerating the reaction rate. The adjustment of the pH value can affect the balance and rate of the chemical reaction in the solution; more accurate monitoring and control of the selenium element in the highland barley growth environment is achieved.

[0046] Furthermore, the specific process of combining the reaction rate evaluation index, the diffusion rate data and the reference diffusion rate data obtained from the preset database to obtain the diffusion rate evaluation index is as follows: the reference diffusion rate data includes a preset diffusion flux threshold, a gas constant, a diffusion coefficient, a preset first diffusion rate allocation weight and a preset second diffusion rate allocation weight, the preset first diffusion rate allocation weight is used to evaluate the influence of the diffusion flux deviation on the diffusion rate evaluation index, and the preset second diffusion rate allocation weight is used to evaluate the influence of the reaction rate evaluation index on the diffusion rate evaluation index; the diffusion rate data and the preset diffusion flux threshold are combined to obtain the diffusion flux deviation, and the diffusion flux deviation is obtained by comparing the difference between the diffusion flux in the process of extracting highland barley grains and the preset diffusion flux threshold with the preset diffusion flux threshold. The result of the ratio operation of the value is expressed as follows: the diffusion flux deviation is used to describe the degree of deviation between the preset diffusion flux threshold and the diffusion flux in the process of highland barley grain extraction; judge whether the diffusion flux deviation is not less than 0, when the diffusion flux deviation is less than 0, the diffusion flux deviation is recorded as 0; when the diffusion flux deviation is not less than 0, the influence of the diffusion flux in the process of highland barley grain extraction is obtained by combining the diffusion flux deviation and the preset first diffusion rate allocation weight; the influence of the reaction rate evaluation index in the process of highland barley grain extraction is obtained by combining the obtained influence of the diffusion flux in the process of highland barley grain extraction and the influence of the reaction rate evaluation index in the process of highland barley grain extraction. The restriction expression of the diffusion rate evaluation index is as follows:

[0047]

[0048] In the formula, K s represents the diffusion rate evaluation index of highland barley grains in the sth preset time period during the extraction process of highland barley grains, s=1,2,...,h, s represents the number of the preset time period, h represents the total number of preset time periods, J s represents the reaction rate evaluation index of highland barley grains in the sth preset time period during the highland barley grain extraction process, D s represents the diffusion flux deviation of highland barley grains in the sth preset time period during the highland barley grain extraction process, E 2s represents the diffusion activation energy of highland barley grains in the sth preset time period during the highland barley grain extraction process, T 2s represents the diffusion temperature of highland barley grains in the sth preset time period during the extraction process of highland barley grains, C s represents the extraction concentration of highland barley grains in the sth preset time period during the extraction process of highland barley grains, D0 represents the diffusion coefficient, R0 represents the gas constant, X0 represents the preset diffusion flux threshold, β1 represents the preset first diffusion rate allocation weight, β2 represents the preset second diffusion rate allocation weight, and e represents a natural constant.

[0049] In this embodiment, the preset diffusion flux threshold is represented by the average value of the diffusion flux data in the process of extracting highland barley grains in the historical period in the preset database, and the diffusion coefficient is represented by the average value of the diffusion coefficient data in the process of extracting highland barley grains in the historical period in the preset database;

[0050] Specifically, the sum of the preset first diffusion rate allocation weight and the preset second diffusion rate allocation weight is 1, for example, the preset first diffusion rate allocation weight is 0.6, and the preset second diffusion rate allocation weight is 0.4; the preset first diffusion rate allocation weight is the weight corresponding to the diffusion flux value preset in the preset database, which represents the numerical value of the influence of the diffusion flux value on the diffusion rate evaluation index. When used, the weight corresponding to the preset diffusion flux value can be directly obtained from the preset database, and the corresponding relationship can be a pre-set mapping relationship. For example, the diffusion flux of the highland barley grain selenium extraction training set and the weight corresponding to the diffusion flux value preset in the preset database form a mapping set, and the real-time diffusion flux is input into the mapping set to obtain the corresponding weight, wherein the mapping relationship can be a one-to-one correspondence or a many-to-one relationship. In this example, its value range is [0, 1].

[0051] When the diffusion flux deviation is not less than 0, the algorithm of this embodiment combines the reaction rate evaluation index and the diffusion rate data, and comprehensively analyzes to obtain the diffusion rate evaluation index. In the algorithm of this embodiment, the reaction rate evaluation index and the diffusion rate data do not exist independently, but are interrelated. The greater the diffusion activation energy, the higher the extraction concentration, and the higher the reaction rate evaluation index do not mean that the diffusion rate evaluation index is higher. The influence of the diffusion temperature should also be considered comprehensively. When the diffusion temperature is too high, the diffusion rate evaluation index may decrease, the thermal stability may decrease, the phase change may occur, and it may even lead to a change in the reaction path or an intensification of the side reaction. These will directly or indirectly inhibit the diffusion process, resulting in a decrease in the diffusion rate evaluation index instead of an increase. The parameters of the algorithm of this embodiment need to consider the impact on the results together.

[0052] Specifically, assuming that the diffusion flux deviation D s The range is 0-10, and the reaction rate evaluation index J s The range is 0-1, the first diffusion rate allocation weight β1 is preset to 0.6, and the second diffusion rate allocation weight β2 is preset to 0.4, as shown in Table 1, which is a statistical table of changes in the diffusion rate evaluation index provided in the embodiment of the present application:

[0053] Table 1 Statistics of changes in diffusion rate evaluation index

[0054] <![CDATA[Diffusion flux deviation D s > <![CDATA[Reaction rate evaluation index J s > <![CDATA[Diffusion rate evaluation index K s > 8.92 0.46 2.9518 5.45 0.62 3.4345 1.71 0.94 5.2626 ... ... ...

[0055] It can be seen from Table 1 that as the diffusion flux deviation Ds The reaction rate evaluation index J s The diffusion rate evaluation index K s Gradually increases; realize more accurate monitoring and regulation of selenium in the highland barley growth environment.

[0056] Furthermore, the specific process of judging whether to adjust the diffusion rate in combination with the preset diffusion rate influence threshold is as follows: W1, judging whether the diffusion rate evaluation index is not lower than the preset diffusion rate influence threshold. When the diffusion rate evaluation index is not lower than the preset diffusion rate influence threshold, no diffusion rate adjustment is performed, otherwise W2 is executed; W2, sending a prompt to the preset personnel to change the solvent type, when the monitored diffusion rate evaluation index is not lower than the preset diffusion rate influence threshold and the reaction rate evaluation index is not lower than the preset reaction rate influence threshold, stop execution, otherwise execute W3, the solvent types include methanol, acetone, ethyl acetate, ether, and acetic acid; W3, sending a prompt to the preset personnel to gradually increase the temperature of the highland barley grain extract by a preset multiple of the preset temperature threshold, when the monitored diffusion rate evaluation index is not lower than the preset diffusion rate influence threshold and the reaction rate evaluation index is not lower than the preset reaction rate influence threshold, stop execution, otherwise feedback is given to the preset personnel.

[0057] In this embodiment, the preset diffusion rate influence threshold is represented by the average value of the diffusion rate influence data during the extraction of highland barley grains in the historical period in the preset database, and the preset temperature threshold is represented by the average value of the diffusion temperature data during the extraction of highland barley grains in the historical period in the preset database. During the extraction of highland barley grains, a prompt is sent to the preset personnel to change the solvent type to accelerate the diffusion behavior of the solute molecules, and the diffusion rate evaluation index and the reaction rate evaluation index after changing the solvent type are monitored. When the monitored diffusion rate evaluation index is not lower than the preset diffusion rate influence threshold and the reaction rate evaluation index is not lower than the preset reaction rate influence threshold, the execution is stopped. Under normal circumstances, increasing the temperature can accelerate the thermal motion of molecules, thereby promoting the increase of reaction rate and diffusion rate; more accurate monitoring and control of selenium in the highland barley growth environment is achieved.

[0058] Furthermore, the specific process of combining the diffusion rate evaluation index, the dissolution rate data and the reference dissolution rate data obtained from the preset database to obtain the dissolution rate evaluation index is as follows: the reference dissolution rate data includes a preset dissolution rate threshold, a preset first dissolution rate allocation weight and a preset second dissolution rate allocation weight, the preset first dissolution rate allocation weight is used to evaluate the influence of the dissolution rate difference on the dissolution rate evaluation index, and the preset second dissolution rate allocation weight is used to evaluate the influence of the diffusion rate evaluation index on the dissolution rate evaluation index; combining the dissolution rate data and the reference dissolution rate data to obtain the dissolution rate difference, the dissolution rate difference is the result of a ratio operation between the difference between the dissolution rate in the extraction process of highland barley grains and the preset dissolution rate threshold and the preset dissolution rate threshold Indicates that the dissolution rate difference is used to describe the degree of deviation between the dissolution rate in the process of highland barley grain extraction and the preset dissolution rate threshold; judge whether the dissolution rate difference is not less than 0. When the dissolution rate difference is less than 0, the dissolution rate difference is recorded as 0; when the dissolution rate difference is not less than 0, the dissolution rate difference and the preset first dissolution rate allocation weight are combined to obtain the influence of the dissolution rate in the process of highland barley grain extraction on the dissolution rate; the diffusion rate evaluation index and the preset second dissolution rate allocation weight are combined to obtain the influence of the diffusion rate evaluation index in the process of highland barley grain extraction; the dissolution rate evaluation index is obtained by combining the influence of the dissolution rate in the process of highland barley grain extraction on the dissolution rate and the influence of the diffusion rate evaluation index in the process of highland barley grain extraction. The restricted expression of the dissolution rate evaluation index is as follows:

[0059]

[0060]

[0061] Where, L s represents the dissolution rate evaluation index of highland barley grains in the s-th preset time period during the extraction process of highland barley grains, s=1,2,...,h, s represents the number of the preset time period, h represents the total number of preset time periods, X s represents the difference in dissolution rate of highland barley grains in the sth preset time period during the extraction process of highland barley grains, C 1s represents the solute saturation concentration of highland barley grains in the sth preset time period during the highland barley grain extraction process, Q s represents the contact area of ​​highland barley grains in the sth preset time period during the highland barley grain extraction process, C 2s represents the solute concentration of highland barley grains in the sth preset time period during the highland barley grain extraction process, T s represents the dissolution time of highland barley grains in the sth preset time period during the extraction process of highland barley grains, K srepresents the diffusion rate evaluation index of highland barley grains in the sth preset time period during the extraction process of highland barley grains, P0 represents the preset dissolution rate threshold, γ1 represents the preset first dissolution rate allocation weight, γ2 represents the preset second dissolution rate allocation weight, and e represents a natural constant.

[0062] In this embodiment, the preset dissolution rate threshold is represented by the average value of the dissolution rate data during the extraction of highland barley grains in the historical period in the preset database, thereby achieving more accurate monitoring and control of the selenium element in the highland barley growth environment.

[0063] Specifically, the sum of the preset first dissolution rate allocation weight and the preset second dissolution rate allocation weight is 1, for example, the preset first dissolution rate allocation weight is 0.4, and the preset second dissolution rate allocation weight is 0.6; the preset first dissolution rate allocation weight is the weight corresponding to the preset dissolution rate value in the preset database, which represents the degree of influence of the dissolution rate value on the dissolution rate evaluation index. When used, the weight corresponding to the preset dissolution rate value can be directly obtained from the preset database, and the corresponding relationship can be a pre-set mapping relationship. For example, the dissolution rate of the selenium extraction training set of highland barley grains and the weight corresponding to the preset dissolution rate value in the preset database form a mapping set, and the real-time dissolution rate is input into the mapping set to obtain the corresponding weight, wherein the mapping relationship can be a one-to-one correspondence or a many-to-one relationship. In this example, its value range is [0, 1].

[0064] When the difference in dissolution rate is not less than 0, the algorithm of this embodiment combines the diffusion rate evaluation index and the dissolution rate data, and comprehensively analyzes the dissolution rate evaluation index. In the algorithm of this embodiment, the diffusion rate evaluation index and the dissolution rate data are not independent, and they are interrelated. The higher the solute saturation concentration and the larger the contact area, the higher the dissolution rate evaluation index. The effects of dissolution time and solute concentration should also be considered comprehensively. When the dissolution time is too long and the solute concentration is too high, the dissolution rate evaluation index may decrease. In the early stage of dissolution, with the full contact and interaction between the solute and the solvent, the dissolution rate is often faster, and the dissolution rate evaluation index is also correspondingly higher. However, as the dissolution process continues, the gradient of the solute concentration gradually decreases, the dissolution driving force weakens, and the dissolution rate gradually slows down. A specific solute concentration may also cause the solvent's solubility for the solute to reach saturation, forming a supersaturated solution or precipitation, thereby hindering the further progress of the dissolution process. The parameters of the algorithm of this embodiment need to consider the impact on the results together.

[0065] Furthermore, the specific process of judging whether to adjust the dissolution rate in combination with the preset dissolution rate influence threshold is as follows: R1, judging whether the dissolution rate evaluation index is not lower than the preset dissolution rate influence threshold. When the dissolution rate evaluation index is not lower than the preset dissolution rate influence threshold, no dissolution rate adjustment is performed, otherwise R2 is executed; R2, performing ultrasonic treatment, when the monitored dissolution rate evaluation index is not lower than the preset dissolution rate influence threshold, the diffusion rate evaluation index is not lower than the preset diffusion rate influence threshold, and the reaction rate evaluation index is not lower than the preset reaction rate influence threshold, the execution is stopped, otherwise R3 is executed, ultrasonic treatment is used to increase the dissolution rate; R3, sending a prompt to the preset personnel to increase the stirring speed step by step by a preset multiple of the preset stirring speed threshold. When the monitored dissolution rate evaluation index is not lower than the preset dissolution rate influence threshold, the diffusion rate evaluation index is not lower than the preset diffusion rate influence threshold, and the reaction rate evaluation index is not lower than the preset reaction rate influence threshold, the execution is stopped, otherwise feedback is given to the preset personnel.

[0066] In this embodiment, the preset dissolution rate impact threshold is represented by the average value of the dissolution rate impact data during the extraction of highland barley grains in the historical period in the preset database, and the preset stirring speed threshold is represented by the average value of the stirring speed data during the extraction of highland barley grains in the historical period in the preset database. Ultrasonic treatment can produce cavitation effect, mechanical effect and thermal effect, which can destroy the cell wall, increase the contact area between the solute and the solvent, and increase the molecular movement speed, thereby accelerating the dissolution, diffusion and reaction rate. Stirring can increase the relative movement between the solute and the solvent, and increase the dispersion of the solute in the solvent, thereby accelerating the dissolution rate. At the same time, stirring also helps to promote the increase of diffusion and reaction rate; more accurate monitoring and control of selenium in the highland barley growth environment is achieved.

The diffusion rate adjustment is used to adjust the diffusion rate evaluation index to no less than the preset diffusion rate influence threshold value. The diffusion rate evaluation index is used to evaluate the influence of the diffusion rate of highland barley grains on the release of selenium during the extraction of highland barley grains; S4, combine the diffusion rate evaluation index, the dissolution rate data, and the reference dissolution rate data obtained from a preset database to obtain a dissolution rate evaluation index, and determine whether to adjust the dissolution rate in combination with the preset dissolution rate influence threshold value. The dissolution rate adjustment is used to adjust the dissolution rate evaluation index to no less than the preset dissolution rate influence threshold value. The dissolution rate evaluation index is used to evaluate the influence of the dissolution rate of highland barley grains on the release of selenium during the extraction of highland barley grains; S5, monitor the selenium release capacity of highland barley grains based on the obtained reaction rate evaluation index, diffusion rate evaluation index, and dissolution rate evaluation index.

[0068] In this embodiment, by adjusting the reaction rate, diffusion rate and dissolution rate, the extraction amount and purity of selenium in highland barley seeds during the extraction process can be improved; and more accurate monitoring and control of selenium in the highland barley growth environment can be achieved.

[0069] In summary, the embodiment of the present application obtains reaction rate data, diffusion rate data and dissolution rate data, and then combines the reaction rate data with the reference reaction rate data to obtain a reaction rate evaluation index, and then combines the reaction rate evaluation index, the diffusion rate data and the reference diffusion rate data to obtain a diffusion rate evaluation index, and finally combines the diffusion rate evaluation index, the dissolution rate data and the reference dissolution rate data to obtain a dissolution rate evaluation index, thereby achieving more accurate monitoring and control of highland barley selenium extraction data, and further achieving more accurate monitoring and control of the selenium element in the highland barley growth environment, effectively solving the problem of low accuracy of selenium element data in monitoring the highland barley growth environment in the prior art.
