When the plant to be irrigated needs to be watered at the root, the driving motor 43 operates to drive the two second transmission members 42 to operate, and the gears 41 in the three installation boxes 27 are driven to rotate by the two second transmission members 42, which are used to drive the first transmission member 40 to drive the second transmission member 42 to rotate. The first lever 34 and the second lever 35 rotate, and the second lever 35 moves the limiting lever 36, so that the limiting portion of the limiting lever 36 is separated from the second protrusion 38. Under the limiting guidance of the limiting block 32, the movable plate 30, the curved rod 29, the connecting rod 28 and the connecting block 25 drive the irrigation pipe 24 to move downward, and the connecting rod 28 slides in the slide groove 26. The slide groove 26 is vertical at the top and inward at the bottom, so that the irrigation pipe 24 gradually approaches the roots of the seedlings during the downward movement, so that it can be sprayed near the roots during subsequent irrigation.

[0062] When the second lever 35 is separated from the limit lever 36, the drive motor 43 stops operating, the limit lever 36 is reset under the action of the torsion spring 37, and the first protrusion 33 moves down and overlaps the limit lever 36, and atomized spray irrigation can be carried out. When the irrigation pipe 24 needs to be moved up and reset, the drive motor 43 continues to operate, so that the first lever 34 moves the first protrusion 33, so that the first protrusion 33 and the movable plate 30 move up, driving the curved rod 29 and the irrigation pipe 24 to move up, and the second protrusion 38 moves up to squeeze the bottom of the limit lever 36, so that the limit lever 36 tilts. After the second protrusion 38 moves to the top of the limit lever 36, the torsion spring 37 drives the limit lever 36 to reset, limits the movable plate 30, and the drive motor 43 stops operating.

[0064] The temperature and humidity data inside the nursery box 1 are obtained in real time through the temperature sensor 5 and the humidity sensor 6, and these data are transmitted and integrated, so as to realize the comprehensive monitoring and centralized management of environmental parameters. The environmental conditions inside the nursery box 1 can be accurately controlled, and environmental anomalies can be discovered and corrected in time, thereby improving the success rate and quality of seedling cultivation. Through data analysis and environmental trend prediction, the environmental adjustment strategy is optimized to ensure that the temperature and humidity inside the nursery box 1 are always within the optimal range, and finally achieve efficient and stable seedling production.

The comprehensive prediction result includes predicted temperature and predicted humidity. The comprehensive prediction result is associated with the corresponding forestry seedling raising device parameters, and a mapping set is constructed and stored in the database.

[0067] The training process of the LSTM model includes data preparation: the input data is the historical parameter data of the forestry seedling device (the state parameters of the fan component 4, the state parameters of the irrigation device, the parameters of the seedling basket 7 and the seedling pot 14, the drainage parameters and the water circulation parameters), which is a time series data set; the output data is the corresponding future temperature and humidity values ​​(label data); the data set is divided into a training set, a validation set and a test set.

[0068] Model construction: Define the architecture of the LSTM model, including LSTM layers, fully connected layers, etc., and set hyperparameters such as the number of LSTM units, learning rate, batch size, etc.

[0069] Model training: input historical time series data (such as the state parameters of the fan 4, the state parameters of the irrigation device, the parameters of the seedling basket 7 and the seedling pot 14, the drainage parameters and the water circulation parameters in the past t time steps), output the predicted future temperature and humidity values, use the loss function (such as the mean square error MSE) to calculate the error between the predicted value and the true value, and update the model parameters through back propagation and optimization algorithms (such as Adam).

[0070] Model validation and testing: Use the validation set to adjust hyperparameters to prevent overfitting, and use the test set to evaluate the performance of the model.

[0071] The training process of the Transformer model includes data preparation: the input data is the same as the LSTM model, which is the historical parameter data of the forestry seedling device; the output data is the corresponding future temperature and humidity values; the data set is divided into training set, validation set and test set.

[0072] Model construction: Define the architecture of the Transformer model, including the encoder, decoder, and multi-head self-attention mechanism, and set hyperparameters such as the number of attention heads, hidden layer dimension, and learning rate.

[0074] Model validation and testing: Use the validation set to adjust hyperparameters to prevent overfitting, and use the test set to evaluate the performance of the model.

[0075] Determining whether the comprehensive prediction result is available specifically includes the following steps: comprehensively analyzing the comprehensive temperature prediction value and the comprehensive humidity prediction value with the actual temperature value and the actual humidity value to obtain a prediction error value. If the prediction error value is less than the prediction error threshold, the comprehensive prediction result is available; if the prediction error value is not less than the prediction error threshold, the comprehensive prediction result is unavailable.

[0076] The first prediction result and the second prediction result are analyzed to obtain a comprehensive prediction result, which includes a comprehensive temperature prediction value and a comprehensive humidity prediction value.

[0077] Among them, the calculation formula for the comprehensive temperature prediction value is:

[0078]

[0079] In the formula, is the comprehensive predicted value of temperature at time t, ω 1 for The weight factor, ω 2 for The weight factor of .

[0080] The calculation formula for the comprehensive predicted humidity value is:

[0081]

[0082] In the formula, is the comprehensive predicted value of humidity at time t, for The weight factor of for The weight factor of .

[0083] The comprehensive temperature prediction value and the comprehensive humidity prediction value are comprehensively analyzed with the actual temperature value and the actual humidity value to obtain the prediction error value. If the prediction error value is less than the prediction error threshold, the comprehensive prediction result is available; if the prediction error value is not less than the prediction error threshold, the comprehensive prediction result is unavailable.

[0084] The calculation formula for the prediction error value is:

[0085]

[0086] In the formula, y wc is the prediction error value, is the actual temperature value at the i-th moment, is the comprehensive predicted value of temperature at the i-th moment, is the actual humidity value at the i-th moment, is the comprehensive predicted value of humidity at the i-th moment, N is the number of time points, and i is the time point number.

[0087] The comprehensive prediction results are compared and analyzed with the actual values, and the usability of the comprehensive prediction results is judged by calculating the prediction error value, which provides a reliable basis for subsequent regulatory decisions, avoids the blindness of regulatory decisions, and enhances the reliability of decisions.

[0088] Accurate environmental simulation and prediction results help to reasonably arrange the operation of equipment such as heating fans, cooling fans, and irrigation components 22, and avoid ineffective operation of equipment due to inaccurate environmental judgment, thereby reducing energy consumption and equipment loss, improving resource utilization efficiency, and reducing seedling costs.

[0089] An adjustment scheme is determined based on a genetic algorithm, and the adjustment scheme includes an optimal temperature and an optimal humidity; and a combination of device operating parameters is determined based on the adjustment scheme.

[0090] Establish constraint conditions, including temperature adjustment constraint and humidity adjustment constraint.

[0091] Temperature regulation constraints, the specific constraints are: humidity is within its regulation range, that is:

[0092] T min ≤T≤T max ;

[0093] Among them, T min is the minimum humidity, T max is the maximum humidity, T is the actual humidity;

[0094] Humidity adjustment constraints, the specific constraints are:

[0095] Humidity is within its regulation range, namely:

[0096] H min ≤H≤H max ;

[0097] Among them, H min is the minimum humidity, H max is the maximum humidity and H is the actual humidity.

[0098] The objective function is:

[0099]

[0100] In the formula, F(T,H) is the comprehensive objective function, g(T) is the effect function of temperature on plant growth, h(H) is the effect function of humidity on plant growth, k(T,H) is the effect function of the interaction between temperature and humidity on plant growth, T opt is the optimum temperature for plant growth, σ T is the width parameter affected by temperature, H opt is the optimum humidity for plant growth, σH is the width parameter of humidity influence, β is the interaction strength coefficient, α 1 is the weight factor of g(T), α 2 is the weight factor of h(H), α 3 is the weight factor of k(T,H).

[0101] The optimal solution is determined based on the ant colony algorithm. The optimal solution includes the optimal temperature and the optimal humidity, which are recorded as the adjustment plan. The optimal temperature and the optimal humidity are compared with the predicted temperature and the predicted humidity in the mapping table to determine the optimal predicted temperature and the optimal predicted humidity in the mapping table. Based on the mapping relationship, the corresponding forestry seedling cultivation device parameters are determined, which are recorded as the device operating parameter combination.

[0102] S1. Encode the decision variables; S2. Randomly generate the initial population; S3. Construct the fitness function; S4. Select excellent individuals from the current population to enter the next generation population based on the roulette selection method; S5. Perform a crossover operation on the selected next generation population to obtain a crossover population; S6. Perform a mutation operation on the crossover population to obtain a mutated population; S7. Repeat steps S4-S6 until the maximum number of iterations is reached, stop calculating and output the current optimal solution, which is the adjustment plan.

[0103] The initial population is a set of candidate solutions randomly generated when the genetic algorithm starts running. Each candidate solution represents a temperature and humidity combination, which is used to optimize the environmental conditions for plant growth. Each individual in the population (i.e., each candidate solution) is usually represented in a coded form. The fitness function (i.e., the objective function) is used to evaluate the pros and cons of each individual, that is, to measure the suitability of the current temperature and humidity combination for plant growth. The smaller the fitness value, the better the individual. The decision variables are determined based on the first prediction result and the second prediction result, and the advantages of the two different models in environmental prediction are used to make the decision variables better reflect the actual temperature and humidity conditions. The subsequent adjustment plan based on these decision variables can better meet the actual needs of the seedling environment and avoid adjustment deviations caused by the prediction error of a single model.

[0104] The objective function includes the influence function of temperature on plant growth, the influence function of humidity on plant growth, and the influence function of the interaction between temperature and humidity on plant growth. The formulation of the adjustment plan not only focuses on the influence of temperature and humidity on plant growth, but also considers the interaction between the two, thereby more comprehensively and scientifically evaluating the influence of different temperature and humidity combinations on plant growth and formulating more accurate adjustment plans.

[0105] By setting constraints, the adjustment scheme is prevented from giving unreasonable temperature and humidity adjustment targets, ensuring the safety and stability of the seedling raising process. The genetic algorithm has the characteristics of global search, encoding decision variables, randomly generating initial populations, selection, crossover and mutation, and continuously searching for possible adjustment schemes in the solution space. Compared with traditional local optimization algorithms, it can jump out of the local optimal solution and is more likely to find the global optimal adjustment scheme, thereby achieving optimal regulation of the seedling raising environment.

[0106] When in use, according to the type of plant to be irrigated, when it is detected that irrigation is needed, and the plant to be irrigated needs root watering, based on the adjustment scheme, the drive motor 43 is controlled to operate, so that the first transmission member 40 drives the first lever 34 and the second lever 35 to rotate, and the second lever 35 pushes the moving part of the limit rod 36 upward, so that the limit part of the limit rod 36 is separated from the second protrusion 38, and under the limit guidance of the limit block 32, the movable plate 30 and the curved rod 29, the connecting rod 28 and the connecting block 25 drive the irrigation pipe 24 to move downward under the action of gravity, and the connecting rod 28 slides in the slide groove 26, and the slide groove 26 is vertical at the top and inward at the bottom, so that the irrigation pipe 24 gradually approaches the root of the seedling during the downward movement, so that it can be sprayed near the root during subsequent irrigation;

[0107] When the second lever 35 is separated from the moving part of the limiting rod 36, the driving motor 43 stops operating, the limiting rod 36 is reset under the action of the torsion spring 37, and the first protrusion 33 moves down and overlaps the limiting rod 36, and atomized spray irrigation can be performed;

[0108] When the irrigation pipe 24 needs to be moved up and reset, the drive motor 43 continues to operate, so that the first lever 34 sequentially moves the limit rod 36 and the first protrusion 33, so that the first protrusion 33 and the movable plate 30 move up, driving the curved rod 29 and the irrigation pipe 24 to move up, and the second protrusion 38 moves up to squeeze the bottom of the limit rod 36, so that the limit rod 36 tilts until the second protrusion 38 moves to the top of the limit rod 36, and the torsion spring 37 drives it to reset, limits the movable plate 30, and the drive motor 43 stops operating.

[0109] When the plants that need irrigation need foliar watering, the drive motor 43 does not operate, and atomized spray irrigation can be directly performed under the operation of the irrigation component 22. In this process, the water falling into the seedling basket 7 flows to the filter box 20 through the drain pipe 12 under the inclined setting of the bottom of the seedling basket 7 and the setting of the pump body 19. After being filtered, it flows to the storage part in the irrigation component 22 through the connecting pipe 21 for subsequent use. When the seedlings need to be taken out, the box door 2 is opened, the seedling basket 7 is pulled outward, the flange 8 slides in the first slide 9, and is pulled to the position of the seedling pot 14 that needs to be taken, and the block 17 is pressed from both sides to separate the block 17 from the card slot, and the seedling pot 14 is moved upward to be taken out.

[0110] When it is detected that temperature adjustment is required, based on the adjustment plan, the heating fan is controlled to operate to increase the temperature, or the cooling fan is controlled to operate to cool down, thereby achieving constant temperature operation.
