[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0018] like Figure 1 As shown, this embodiment provides a decision support system for the prevention and control of swine bacterial diseases, including: Data acquisition module: used to collect real-time data on piggery environmental parameters and pig health status; The data acquisition module includes: Environmental sensor unit: installed inside the pigsty, used to collect data on temperature, humidity, ammonia concentration and ventilation volume; The health monitoring unit includes a body temperature sensor and an image recognition device. The body temperature sensor is attached to the pig's body surface, and the image recognition device is used to capture abnormal behavioral characteristics of the pig herd, such as capturing pig behavior (e.g., coughing, lameness) through a camera. Timely detection of abnormal body temperature (threshold: T) pig Temperatures >40℃ and abnormal behaviors (such as lying down for more than 80% of the time) The data transmission unit is connected to the environmental sensor group and the health monitoring module to transmit the collected data to the decision control module in real time.
[0019] By linking environmental sensor groups (temperature / humidity, ammonia, ventilation volume) with health monitoring units (body temperature sensor + image recognition) in real time, a three-in-one monitoring network of "environment, physiology and behavior" is formed. For example, when the image recognition device captures that the pigs spend more than 80% of their time lying down and their body temperature is >40℃, the system automatically triggers the pathogen analysis module and matches potential pathogens (such as Streptococcus suis) within 0.5 seconds using the KNN algorithm, which improves efficiency by more than 90% compared to traditional manual inspection.
[0020] Pathogen analysis module: used to determine the types of bacteria infecting the target pig herd and their optimal growth environment parameter range; The pathogen analysis module specifically includes: Bacterial database unit: Stores optimal growth temperature, humidity, pH value and drug resistance data of common swine bacterial pathogens, such as storing the optimal growth parameters of pathogenic bacteria; Matching unit: Used to match the corresponding pathogenic bacteria species and their sensitive drug types from the bacterial database based on the health status data of the pig herd; Specifically, based on pig herd health data (such as body temperature and behavioral abnormalities), the KNN algorithm is used to match pathogen types in the database. The formula for calculating the matching degree is as follows: Where: x i For current data characteristics (such as body temperature, humidity); y i For pathogen characteristics in the database; ω i The feature weights are (e.g., body temperature weight = 0.6).
[0021] Dynamic correction unit: used to update the environmental adaptability model of pathogenic bacteria by combining real-time environmental parameters with historical epidemic data; If gradient descent is used to adjust the optimal parameters, the specific formula involved is as follows: Where α is the learning rate (default 0.1); The original optimal temperature (known or initial setting value); The current ambient temperature; This is the updated optimal temperature, used to dynamically adapt to environmental changes.
[0022] Prediction and early warning module: Based on machine learning models (such as random forest), it analyzes the correlation between historical environmental data and epidemics, predicts the risk of pathogen proliferation in the next 24-48 hours, and triggers audible and visual alarms and pushes emergency response plans to user terminals when environmental parameters deviate from the target control range or the abnormal proportion of pigs exceeds the threshold. The prediction and early warning module includes: Data preprocessing unit: Normalizes the raw data based on the input pathogen type, environmental parameters (temperature, humidity, etc.), and historical epidemic data, and extracts time-series features (such as the 24-hour moving average). The specific normalization formula is as follows: in The data points are standardized, with a mean of 0 and a standard deviation of 1; σ is the standard deviation of the dataset, which measures the dispersion of the data; μ is the mean of the dataset; and x is the original data point, representing the specific value collected at a certain moment (such as temperature, humidity, etc.).
[0023] Model training unit: Based on the random forest algorithm, the prediction model is trained to learn the correlation between environmental parameters and pathogen proliferation, and outputs the risk level (low / medium / high) for the next 12-48 hours; the formulas involved in the above random forest algorithm are as follows: in, Input data (environmental parameters + historical epidemic data); The number of decision trees is set (default 100), thus enabling 48-hour risk level prediction; Risk mapping unit: Converts risk levels into specific prevention and control recommendations (e.g., "high risk" corresponds to "increase disinfection frequency to once per hour"), and marks the confidence level; Historical database: Stores long-term environmental monitoring data, pathogen detection results, and records of control effects, supporting iterative model training and validation; Decision control module: used to perform correlation analysis between pig herd health status data and the optimal growth environment parameter range of bacteria, and generate environmental regulation instructions and drug administration strategies; The decision control unit specifically includes: Parameter comparison unit: Used to calculate the difference between the current pigsty environmental parameters and the optimal bacterial growth environment parameter range, to determine the target control range for inhibiting bacterial growth; the specific formula for calculating the difference between the current environment and the optimal bacterial parameters is as follows: Strategy generation unit: Used to generate composite instructions for ventilation, temperature and humidity adjustment, and disinfection frequency based on the target control range using a fuzzy control algorithm. Specifically, the temperature control formula is as follows: Achieve temperature and humidity control error of less than ±1°; Priority allocation unit: used to allocate medication order and dosage according to the degree of infection in the pig herd.
[0024] Execution module: Used to adjust the environmental parameters of the pig house according to environmental control instructions, and to administer targeted drugs to the target pig herd according to the drug administration strategy; The execution module includes: Environmental control unit: includes variable frequency fan, spray cooling device and ultraviolet disinfection lamp. The variable frequency fan and spray cooling device are linked to achieve precise temperature and humidity regulation. Intelligent drug delivery device: includes a drug storage bin, a metering pump, and a directional nozzle. The directional nozzle is installed above the feeding trough in the pig pen for spraying atomized drugs. The intelligent drug delivery device has a rotatable nozzle, whose spray angle is controlled by a servo motor, and an anti-clogging filter is provided at the nozzle outlet. The directional nozzle is adjusted at an angle by a servo motor to ensure that the medicine covers the target pigs; Both the environmental control components and the intelligent drug delivery device are electrically connected to the decision control unit.
[0025] Adaptive optimization module: Dynamically adjusts control strategies through reinforcement learning to balance control effectiveness with resource consumption (such as energy saving and reducing drug use). The adaptive optimization module includes: Effectiveness evaluation sub-unit: Real-time collection of actual data after implementation (pathogen inhibition rate, pig herd health recovery rate, energy consumption and drug consumption), and calculation of prevention and control effectiveness and cost indicators; The strategy optimization subunit, based on reinforcement learning algorithms (such as DQN), dynamically adjusts parameters such as temperature and humidity thresholds and drug dosage with the goal of maximizing pathogen inhibition rate and minimizing resource consumption. The strategy is optimized using the DQN algorithm, with the reward function as follows: Where λ i These are the weighting coefficients, default. ; Further improve the efficiency of prevention and control.
[0026] Parameter update subunit: Feeds back the optimized strategy parameters (such as "lower the temperature threshold by 1℃") to the decision control unit in real time for the next round of decision generation; Real-time feedback interface: connects the execution unit and the strategy optimization subunit to ensure low-latency data transmission and support second-level response.
[0027] The adaptive optimization module dynamically balances the control effect and resource consumption through the DQN algorithm. For example, when the activity level of pigs decreases at night, the system automatically lowers the temperature threshold by 1°C and reduces ventilation by 20%, ensuring a pathogen inhibition rate of >90% while reducing energy consumption by 15% and drug usage by 12%.
[0028] In the operation of this embodiment, a closed-loop logic of data acquisition, analysis, decision-making, and execution optimization is coordinated to form a full-chain intelligent prevention and control system. The data acquisition module captures temperature and humidity, ammonia concentration, pig herd temperature and behavior data in real time through environmental sensors and health monitoring units. The data is then uploaded to the pathogen analysis module in seconds via the data transmission unit. The latter uses the KNN algorithm to match the bacterial database and combines the gradient descent method to dynamically correct the pathogen growth model, locking in potential pathogens and their sensitive agents within 0.5 seconds.
[0029] Meanwhile, the prediction and early warning module analyzes historical data based on the random forest algorithm, predicts the risk of pathogen proliferation 48 hours in advance, and normalizes the feature values through the data preprocessing unit, mapping the risk level to an "environmental control + drug administration" strategy.
[0030] The same decision control module compares the current environment with the optimal growth parameters of the pathogen, uses a fuzzy control algorithm to generate compound instructions, and executes them precisely through the variable frequency fan, spray device and intelligent drug delivery system of the execution module. The directional nozzle achieves "millimeter-level" drug coverage in the pig pen through a servo motor, saving 60% of the drug dosage compared to administering the drug to the entire herd.
[0031] Furthermore, the adaptive optimization module, based on the DQN reinforcement learning algorithm, dynamically adjusts temperature and humidity thresholds and drug dosage. For example, it automatically lowers the temperature by 1°C and reduces ventilation by 20% at night, reducing energy consumption by 15% while maintaining an antibacterial rate of >90%. All modules ultimately construct a smart prevention and control closed loop of "real-time monitoring - precise traceability - intelligent early warning - targeted intervention - dynamic optimization," reducing drug usage by 50%-70% and breeding costs by 15%-20%, providing an efficient, precise, and sustainable bacterial disease prevention and control solution for large-scale farming.

In S4, the determination of the temperature and humidity control threshold includes: calculating the deviation between the current environmental parameters and the optimal growth range of bacteria through a fuzzy control algorithm, dynamically adjusting the target temperature and humidity range to ensure that it simultaneously meets the requirements of inhibiting bacterial reproduction and the comfort of the pig herd. The allocation of drug administration priorities includes: prioritizing the administration of high-concentration drugs to high-risk pigs based on the severity of individual infections in the pig herd and data on the drug resistance of pathogenic bacteria, and providing real-time feedback on efficacy data to adjust subsequent drug administration strategies; S5. Execution and control: Based on the compound decision-making instructions, the ventilation and spraying equipment in the pig house are adjusted in a coordinated manner to control the temperature and humidity, and the targeted drug delivery device is activated to spray antibacterial agents onto the target pig herd according to priority.
