Description

Technical Field

[0001] This invention relates to the field of seed coating agents, and more particularly to an apparatus and control method for preparing seed coating agents for seeds. Background Technology

[0002] Seed coating agents come in liquid and solid powder forms; some are pre-formed for long-term storage, while others are made and used immediately. They were developed based on suspension concentrates, powders, and wettable powders. The active ingredient must be released gradually without causing toxicity to crop germination and growth. The seed coating film must be permeable to water and air, and must not affect seed life and respiration. Seed coating agents are characterized by high efficiency, economy, safety, long residual effect, and multifunctionality. They are factory-produced powders containing various pesticide components, with a moldable appearance, and are brick-red in color. Coating seeds with this agent prevents soil-borne pests and diseases after sowing. Simultaneously, as the seed germinates and emerges, the agent is gradually released from the seed coating and absorbed by the crop, also controlling above-ground pests and diseases. However, traditional seed coating agent preparation processes generally suffer from low parameter control precision, large quality fluctuations, and unstable production efficiency. Summary of the Invention

[0003] This invention overcomes the shortcomings of the prior art and provides a seed coating agent preparation device and control method.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: The first aspect of the present invention provides an apparatus for preparing seed coating agents, comprising: Heating wire, preparation tank and stirring mechanism. Viscosity sensor, density sensor and temperature sensor are installed in the preparation tank. Physical property data of seed coating agent are obtained through viscosity sensor, density sensor and temperature sensor. A torque sensor is installed on the stirring mechanism to monitor changes in stirring resistance and the physical properties of the seed coating agent to assess changes in the viscosity of the solution. The amount of thickener added is then dynamically adjusted based on the changes in the viscosity of the solution. An infrared spectroscopy probe is installed above the preparation tank to detect the chemical concentration of the active ingredients in the seed coating agent in real time, and the pH value is monitored in combination with an ion-selective electrode.

[0005] Furthermore, in the seed coating agent preparation device, the seed coating agent preparation device includes a support frame, on which a preparation tank is installed, and an infrared spectral probe is installed on the stirring mechanism, with the infrared spectral probe facing the preparation tank.

[0006] Furthermore, in the seed coating agent preparation device, the stirring mechanism includes a second bracket mounted on the support frame, and an infrared spectral probe is mounted on the second bracket.

[0007] Furthermore, in the seed coating agent preparation device, the stirring mechanism also includes a drive motor, the output end of which is connected to a stirring rod, and a stirring ring is installed on the stirring rod.

[0008] Furthermore, in the seed coating agent preparation device, a torque sensor is installed on the stirring ring. By monitoring changes in stirring resistance and the physical properties of the seed coating agent, the viscosity of the solution is evaluated, and the amount of thickener added is dynamically adjusted based on the viscosity changes.

[0009] Furthermore, in the seed coating agent preparation device, the preparation barrel is equipped with a drain pipe and a pulley at the bottom.

[0010] A second aspect of the present invention provides a control method for a seed coating agent preparation apparatus, applicable to any of the seed coating agent preparation apparatuses described in the present invention, comprising the following steps: A physical parameter monitoring layer was constructed, and a high-precision viscosity sensor, a nanometer-precision viscosity sensor, and a temperature sensor were installed inside the preparation tank to collect data on the physical properties of the seed coating agent. By installing a high-sensitivity torque sensor in the stirring mechanism, the change in stirring resistance is monitored, and the change in the viscosity of the seed coating agent is evaluated in combination with the physical property data of the seed coating agent. The characteristics of the viscosity change of the medicine solution within a preset time period are obtained, and it is determined whether there are any abnormalities in the characteristics of the viscosity change of the medicine solution within the preset time period. When an anomaly is detected, the process parameters of the seed coating agent preparation device are adjusted according to the characteristics of the viscosity change of the drug solution within a preset time.

[0011] Furthermore, in the control method of the seed coating agent preparation device, a high-sensitivity torque sensor is installed in the stirring mechanism to monitor changes in stirring resistance and evaluate changes in the viscosity of the solution by combining the physical property data of the seed coating agent. Specifically: Collect physical property data of different seed coating agents and viscosity characteristics of seed coating agent solutions under changes in stirring resistance, and construct a knowledge graph. Input the physical property data of the different seed coating agents and viscosity characteristics of seed coating agent solutions under changes in stirring resistance into the knowledge graph for storage. By installing a high-sensitivity torque sensor in the stirring mechanism, the change in stirring resistance is monitored, and the characteristic data of the change in stirring resistance within a preset time are obtained, thereby collecting the physical property data of the seed coating agent. The data on the variation characteristics of stirring resistance within the preset time period and the physical property data of the seed coating agent are combined and input into the knowledge graph for analysis. The viscosity change characteristics of the drug solution are analyzed and evaluated, and the viscosity change characteristics are output.

[0012] Furthermore, in the control method of the seed coating agent preparation device, the viscosity change characteristics of the liquid within a preset time are obtained, and it is determined whether there are any abnormalities in the viscosity change characteristics of the liquid within the preset time. Specifically: Set a viscosity threshold for the liquid medicine, and determine whether all viscosity characteristic data of the liquid medicine within the preset time period are greater than the viscosity threshold for the liquid medicine. If all the viscosity characteristic data of the medicine solution within the preset time period are greater than the viscosity threshold of the medicine solution, a normal prompt will be generated. If the viscosity characteristic data of the medicine solution changes within the preset time period is not uniformly greater than the viscosity threshold of the medicine solution, an abnormal prompt will be generated.

[0013] Furthermore, in the control method of the seed coating agent preparation device, when an abnormality occurs, the process parameters of the seed coating agent preparation device are adjusted according to the viscosity change characteristics of the solution within a preset time. Specifically: When an abnormality occurs, the operating parameters of the drive motor and the heating wire are re-initialized, and the seed coating agent preparation device is controlled according to the operating parameters of the drive motor and the heating wire. Collect the viscosity change characteristics of the medicine solution within a preset time period, and determine whether there are any abnormalities in the viscosity change characteristics of the medicine solution within the preset time period; When there are no abnormalities, the seed coating agent preparation device is controlled according to the working parameters of the drive motor and the heating wire. When an abnormality occurs, continuously adjust the operating parameters of the drive motor and the heating wire. This invention addresses the shortcomings of the prior art and has the following beneficial effects: This invention constructs a physical parameter monitoring layer by installing a precision viscosity sensor, a nanometer-precision viscosity sensor, and a temperature sensor inside the preparation tank to collect physical property data of the seed coating agent. Furthermore, a high-sensitivity torque sensor is installed in the stirring mechanism to monitor changes in stirring resistance. Combined with the physical property data of the seed coating agent, the viscosity change of the solution is evaluated, thereby obtaining the viscosity change characteristics of the solution within a preset time period. The invention then determines whether there are any anomalies in the viscosity change characteristics within the preset time period. Finally, if an anomaly is found, the process parameters of the seed coating agent preparation device are adjusted based on the viscosity change characteristics within the preset time period. This invention solves the problems of low parameter control precision, large quality fluctuations, and unstable production efficiency commonly found in traditional seed coating agent preparation processes by installing precision viscosity sensors, nanometer-precision viscosity sensors, and temperature sensors inside the preparation tank to collect physical property data of the seed coating agent and adjust the process parameters of the seed coating agent preparation device based on the viscosity change characteristics of the solution within a preset time period.

[0020] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0021] like Figure 1 as well as Figure 2 As shown, the first aspect of the present invention provides a seed coating agent preparation apparatus, comprising: Heating wire (not shown), preparation tank 1 and stirring mechanism 2. Viscosity sensor, density sensor and temperature sensor are installed in preparation tank 1. Physical property data of seed coating agent are obtained through viscosity sensor, density sensor and temperature sensor. A torque sensor is installed on the stirring mechanism 2. By monitoring changes in stirring resistance and the physical properties of the seed coating agent, the viscosity of the solution is evaluated. The amount of thickener added is dynamically adjusted based on the changes in the viscosity of the solution. An infrared spectral probe 3 is installed above the preparation tank 1. The chemical concentration of the active ingredient in the seed coating agent is detected in real time by the infrared spectral probe, and the pH value is monitored in combination with the ion selective electrode.

[0022] It should be noted that the powder, water, or liquid medicine are mixed in the specified proportions and placed into the preparation container 1. The powder, water, or liquid medicine is stirred by the stirring mechanism 2. The physical property data of the seed coating agent are obtained through viscosity sensor, density sensor, and temperature sensor. The resistance change is collected by torque sensor. The amount of thickener added is dynamically adjusted in combination with the change of the viscosity of the liquid medicine. For example, when the viscosity of the liquid medicine does not meet the preset threshold, the amount of thickener added is increased and the working parameters of the stirring mechanism are dynamically adjusted.

[0023] Furthermore, in the seed coating agent preparation device, the seed coating agent preparation device includes a support frame 101, on which a preparation tank 1 is installed, and an infrared spectral probe is installed on the stirring mechanism 2, with the infrared spectral probe facing the preparation tank 2.

[0024] Furthermore, in the seed coating agent preparation device, the stirring mechanism includes a second bracket 102 mounted on the support frame 101, and an infrared spectral probe 201 is mounted on the second bracket 102.

[0025] Furthermore, in the seed coating agent preparation device, the stirring mechanism 2 also includes a drive motor 201, the output end of which is connected to the stirring rod 202, and a stirring ring 203 is installed on the stirring rod 202.

[0026] Furthermore, in the seed coating agent preparation device, a torque sensor is installed on the stirring ring 203. By monitoring changes in stirring resistance and the physical properties of the seed coating agent, the viscosity of the solution is evaluated, and the amount of thickener added is dynamically adjusted based on the viscosity changes.

[0027] It should be noted that nanoscale precision viscosity sensors (range 0.1-5000 mPa·s, accuracy ±2%), density sensors (accuracy ±0.001 g / cm³), and temperature sensors (-50~150℃, accuracy ±0.1℃) are installed in the mixing tank to monitor the basic physical properties of the seed coating agent in real time. A high-sensitivity torque sensor is installed inside the coating machine to indirectly assess changes in the viscosity of the solution by monitoring changes in stirring resistance. A miniaturized near-infrared spectroscopy probe (wavelength range 1100-2300nm) can be used to detect the chemical concentration of active ingredients (such as chlorpyrifos, carbendazim, and imazalil) in the seed coating agent in real time. Combined with ion-selective electrodes to monitor pH value (measurement range 0-14, accuracy ±0.01) and conductivity (0-200 mS / cm, accuracy ±1%), the stability of the active ingredients within the formulation range is ensured. This allows for an increase in the amount of thickener added, thereby optimizing the viscosity of the solution and improving the quality consistency and production efficiency of the seed coating agent preparation.

[0028] Furthermore, in the seed coating agent preparation device, the preparation barrel is equipped with a drain pipe 4 and a pulley 5 at the bottom.

[0029] A second aspect of the present invention provides a control method for a seed coating agent preparation apparatus, applicable to any of the seed coating agent preparation apparatuses described in the present invention, comprising the following steps: A physical parameter monitoring layer was constructed, and a high-precision viscosity sensor, a nanometer-precision viscosity sensor, and a temperature sensor were installed inside the preparation tank to collect data on the physical properties of the seed coating agent. It should be noted that a nanometer-precision viscosity sensor (range 0.1-5000 mPa·s, accuracy ±2%), a density sensor (accuracy ±0.001 g / cm³), and a temperature sensor (-50~150℃, accuracy ±0.1℃) are installed in the mixing tank to monitor the basic physical properties of the seed coating agent in real time. A high-sensitivity torque sensor is installed inside the coating machine to indirectly assess changes in the viscosity of the solution by monitoring changes in stirring resistance.

[0030] By installing a high-sensitivity torque sensor in the stirring mechanism, the change in stirring resistance is monitored, and the change in the viscosity of the seed coating agent is evaluated in combination with the physical property data of the seed coating agent. The characteristics of the viscosity change of the medicine solution within a preset time period are obtained, and it is determined whether there are any abnormalities in the characteristics of the viscosity change of the medicine solution within the preset time period. When an anomaly is detected, the process parameters of the seed coating agent preparation device are adjusted according to the characteristics of the viscosity change of the drug solution within a preset time.

[0031] It should be noted that this invention collects viscosity data, real-time operating temperature data, and density data of the seed coating agent by installing a precision viscosity sensor and a temperature sensor inside the preparation tank, thereby forming physical property data. Based on the viscosity change characteristics of the drug solution within a preset time, the process parameters of the seed coating agent preparation device are adjusted, solving the problems of low parameter control precision, large quality fluctuations, and unstable production efficiency that are common in traditional seed coating agent preparation processes.

[0032] Furthermore, in the control method of the seed coating agent preparation device, a high-sensitivity torque sensor is installed in the stirring mechanism to monitor changes in stirring resistance and evaluate changes in the viscosity of the solution by combining the physical property data of the seed coating agent. Specifically: Collect physical property data of different seed coating agents and viscosity characteristics of seed coating agent solutions under changes in stirring resistance, and construct a knowledge graph. Input the physical property data of the different seed coating agents and viscosity characteristics of seed coating agent solutions under changes in stirring resistance into the knowledge graph for storage. By installing a high-sensitivity torque sensor in the stirring mechanism, the change in stirring resistance is monitored, and the characteristic data of the change in stirring resistance within a preset time are obtained, thereby collecting the physical property data of the seed coating agent. The data on the variation characteristics of stirring resistance within the preset time period and the physical property data of the seed coating agent are combined and input into the knowledge graph for analysis. The viscosity change characteristics of the drug solution are analyzed and evaluated, and the viscosity change characteristics are output.

[0033] It should be noted that, under other conditions (such as the thickener meeting the requirements), this method can evaluate the physical properties of the current seed coating agent and the viscosity characteristics of the seed coating agent solution under changes in stirring resistance, thereby further improving the preparation quality of the seed coating agent.

[0034] Furthermore, in the control method of the seed coating agent preparation device, the viscosity change characteristics of the liquid within a preset time are obtained, and it is determined whether there are any abnormalities in the viscosity change characteristics of the liquid within the preset time. Specifically: Set a viscosity threshold for the liquid medicine, and determine whether all viscosity characteristic data of the liquid medicine within the preset time period are greater than the viscosity threshold for the liquid medicine. If all the viscosity characteristic data of the medicine solution within the preset time period are greater than the viscosity threshold of the medicine solution, a normal prompt will be generated. If the viscosity characteristic data of the medicine solution changes within the preset time period is not uniformly greater than the viscosity threshold of the medicine solution, an abnormal prompt will be generated.

[0035] Furthermore, in the control method of the seed coating agent preparation device, when an abnormality occurs, the process parameters of the seed coating agent preparation device are adjusted according to the viscosity change characteristics of the solution within a preset time. Specifically: When an abnormality occurs, the operating parameters of the drive motor and the heating wire are re-initialized, and the seed coating agent preparation device is controlled according to the operating parameters of the drive motor and the heating wire. Collect the viscosity change characteristics of the medicine solution within a preset time period, and determine whether there are any abnormalities in the viscosity change characteristics of the medicine solution within the preset time period; When there are no abnormalities, the seed coating agent preparation device is controlled according to the working parameters of the drive motor and the heating wire. When an abnormality occurs, continuously adjust the operating parameters of the drive motor and the heating wire.

[0036] In addition, this method also includes: We acquire data on the formulation composition, coating effect, biological effects, and safety of seed coating agents, and analyze the complex nonlinear relationships between these data based on the Gradient Boosting Decision Tree (GBDT) algorithm. Obtain the formulation composition and safety data of the current seed coating agent, and use the gradient boosting decision tree algorithm to analyze the coating effect and biological effect of the current seed coating agent based on the formulation composition and safety data of the current seed coating agent. Set evaluation indicators for coating effect and biological effect, and determine whether the coating effect and biological effect of the current seed coating agent are both greater than the evaluation indicators for coating effect and biological effect. Seed coating agents with coating effects and biological efficacy evaluation indicators that are greater than those corresponding to the coating effects and biological efficacy evaluation indicators are considered the most suitable formulation types.

[0037] It should be noted that, based on the Gradient Boosting Decision Tree (GBDT) algorithm, the complex nonlinear relationship between formulation composition and coating effect (film formation, stability), biological effect (pest and disease control, growth promotion), and safety (phytotoxicity, environmental impact) is analyzed. Considering the formulation effect, cost (raw material cost controlled at 10,000-50,000 RMB / ton) and environmental friendliness, the seed coating agent with a coating effect and biological effect evaluation index greater than the aforementioned coating effect and biological effect evaluation index is taken as the most suitable formulation type. This solves the regional adaptability problem of seed coating agents and makes the seed coating agents meet the predetermined requirements.

[0038] In addition, this method also includes: Construct a physical entity layer, in which seed coating agent production equipment, sensor networks and actuators, as well as physical entities of seed coating equipment and planting environment are configured; Among them, seed coating agent production equipment (such as reaction vessels, mixing tanks, coating machines), sensor networks and actuators, as well as seed coating equipment and planting environment, are the real-world basis for digital twins.

[0039] The high-fidelity virtual model constructed based on the physical entity includes a 3D model of the equipment, a hydrodynamic model of the seed coating agent, a film-forming process model, and a seed germination and growth model. Among them, the high-fidelity virtual models built based on physical entities include 3D models of equipment, fluid dynamics models of seed coating agents, film-forming process models, and seed germination and growth models, which accurately reflect the structure, function, and behavior of physical entities.

[0040] It integrates real-time data, historical data, simulation data, and domain knowledge data collected from physical entities to form data that drives the operation of digital twins, and encapsulates functional modules for process simulation, effect prediction, optimization analysis, and virtual experimentation. Integrating real-time data (such as temperature, viscosity, pH), historical data, simulation data, and domain knowledge data (such as the experience of agricultural experts and literature) collected from physical entities forms the data foundation driving the operation of digital twins.

[0041] Using data from the digital twin, computational fluid dynamics (CFD) was used to simulate the flow, atomization, and distribution of seed coating agents within the coating machine. Based on molecular dynamics, the self-assembly process of film-forming agents on the seed surface was simulated at the microscale, and the formation mechanism of the dual structure of "nanoscale bottom water-locking membrane + microporous breathable mesh membrane" was analyzed. In this process, computational fluid dynamics (CFD) is used to simulate the flow, atomization, and distribution of the seed coating agent within the coating machine, thereby optimizing the stirring parameters and improving the coating uniformity.

[0042] It encapsulates various functional modules, including process simulation, effect prediction, optimization analysis, and virtual experimentation, and provides services in the form of APIs to support calls from different application scenarios.

[0043] Virtual coated seeds were placed under different soil and climate conditions to simulate seed germination, seedling growth, and pest and disease infection processes, and to predict the effects of seed coating agents on emergence rate, plant growth, and final yield.

[0044] Among them, virtual coated seeds are placed under different soil and climate conditions to simulate seed germination, seedling growth and pest and disease infection processes, predict the impact of seed coating agents on seedling emergence rate, plant growth and final yield, and provide a basis for decision-making for regionalized formulation application.

[0045] It should be noted that by constructing a virtual mapping of the seed coating agent preparation workshop and the seed coating process, process simulation, effect evaluation and parameter optimization can be realized in the digital space, which greatly improves the scientific nature and accuracy of seed coating agent research and application.
