Description

Technical Field

[0001] The present invention relates to the technical field of rice seedling pest identification and protection, and in particular to an intelligent pest identification and prevention system for rice seedling stage. Background Art

[0002] Rice is an important food crop. Besides being edible, it can be used to make starch, wine, and vinegar. Rice bran can be used to make sugar, extract oil, and extract furfural, which is also used in industry and medicine. Rice stalks are excellent feed, a raw material for papermaking, and a weaving material. Rice sprouts and roots are used medicinally. To meet people's food needs, rice production must be stable. However, pests and diseases are a major cause of rice yield decline. Promptly detecting rice damage can help increase yields.

[0003] Traditional rice pest and disease survey methods often require significant manpower and time, and can only collect data on pests and diseases on the surface of rice plants. However, data on pests and diseases deeper within the rice plant is often overlooked. The development of a rice image acquisition device can effectively address the difficulty of traditional rice pest and disease survey methods in capturing data on pests and diseases obscured by the rice. This improves the efficiency, accuracy, and repeatability of data collection, providing more comprehensive and accurate data support for rice pest and disease research. Automated data acquisition reduces human interference, thereby improving survey repeatability. Furthermore, deep learning algorithms are used for analysis and identification, further enhancing survey efficiency and accuracy. Therefore, there is an urgent need for an intelligent pest and disease identification and control system for rice seedlings. Summary of the Invention

A medicine outlet pipe 8 connected to the interior of the medicine box 1 is fixedly connected to the lower end of the front side. A medicine delivery pipe 9 bent to one side is fixedly connected to the front end of the medicine outlet pipe 8. The medicine delivery pipe 9 is placed along the edge of the rice field. Several evenly distributed medicine delivery branches 10 are fixedly connected to the front end of the medicine delivery pipe 9. Evenly distributed mounting platforms 2 are set on the medicine delivery branches 10. The interior of the mounting platform 2 is connected to the interior of the medicine delivery branch 10, and an inverted conical fixing anchor 12 is fixedly connected to the lower end of each mounting platform 2 and inserted into the soil of the rice field.

[0046] A delivery pump 11 is provided at the position before the medicine delivery pipe 9 is connected to the medicine delivery branch pipe 10, which is used to deliver the medicine inside the medicine box 1 to the delivery branch pipe 10. A water delivery support pipe 3 is fixedly connected to the upper side of each mounting platform 2. The interior of the water delivery support pipe 3 and the interior of the mounting platform 2 are connected together, and the lower end of the outer front side of the water delivery support pipe 3 is fixedly connected to a servo electric cylinder 13 with a telescopic rod facing upward. A lifting support ring 5 is fixedly connected to the telescopic rod at the upper end of the servo electric cylinder 13. The lifting support ring 5 is sleeved on the water delivery support pipe 3 and can move up and down. Several evenly distributed mounting grooves 17 are opened on the outer upper side of the adjustment lifting ring 602, and a rolling ball 18 is provided inside each mounting groove 17. An adjusting lifting ring 602 is provided on the outer upper part of the lifting support ring 5, and the bottom of the adjusting lifting ring 602 is in contact with the ball 18, so that the adjusting lifting ring 602 can both slide up and down and rotate without affecting the adjusting lifting ring 602.

[0047] A connecting ring 4 is rotatably connected to the upper end of the outside of the water supply support pipe 3, and a mounting rod 15 is hinged on the front, back and both sides of the outside of the connecting ring 4. There is a pipe ring on the upper end of the mounting rod 15 that is away from each other, and a water spray bend 16 is installed inside. The water spray bend 16 is bent 45° clockwise when viewed from above, and the end that sprays water at the tail end is bent 45° upward. A diverter box 14 is rotatably connected to the upper end of the water supply support pipe 3, and the interior of the diverter box 14 and the interior of the water spray bend 16 are through-connected together, and the outside of the diverter box 4 is fixedly connected to the water supply hose 21 fixedly connected at the front, back and both sides and the end of the water spray bend 16 that is close to each other, so as to deliver medicine to the interior of the water spray bend 16.

The central control cabinet 7 controls the delivery pump 11 and the servo electric cylinder 13 through the pan-tilt system and the integrated control module, and is interconnected with the drone 19 through the central control pan-tilt system. The drone 19 takes pictures of various areas of the rice field and uploads them through the high-resolution fast camera 20 fixedly connected to the front side of the bottom.

[0050] An intelligent identification and prevention system for rice pests and diseases in the seedling stage, the specific steps are as follows:

[0051] S1: Collect images of rice pests and diseases to establish a database. Manually take photos of rice damaged by pests and diseases, store the images through a pan-tilt system, and establish a database.

[0052] S2: The drone 19 is launched regularly. The paddy field is divided into 14m×14m areas through BIM modeling. The paddy field area between the four mounting platforms 2 is one of the divided areas. The drone 19 uses a high-resolution fast camera 20 to take pictures of each divided area and transmits the pictures to the control terminal via the gimbal.

[0053] S3: Compare the images taken by the drone 19 with the image database using the FRNet network structure to determine whether there is pest damage in the corresponding area and the extent of the damage. The drone is then flown back and the comparison results are used to determine whether to spray pesticides and the amount of pesticide to be sprayed.

[0054] Among them, the perceptron is used to train the model on the pictures of rice with pests and diseases, and then the judgment output is made:

[0055]

[0056] xi is the input value; wi is the weighted summation parameter, and θ is the threshold;

[0057] when If the threshold is exceeded, the output is 1, otherwise the output is 0. When the y output is 1, the signal is transmitted, the neural network node is activated, and nonlinear transformation is performed. It is called activation function;

[0058] Then use the neural network output layer activation function Normalize and make predictions for the model;

[0059] σ k is the value of each activated neuron in the common layer, a kis the corresponding label in the activation of the output layer, and e is a constant;

[0060] After the model of rice pests and diseases is constructed, the model of rice pests and diseases is trained to obtain the characteristics of rice pests and diseases;

[0061] Through the loss function cross entropy formula To judge the poor performance of the neural network;

[0062] where y i is the actual label, m is the training sample, is the training sample size, y i is the predicted value, is the actual label;

[0063] When training the stochastic gradient descent of the test, you need to use the function To speed up the iteration speed of the operation, w is the weighted summation parameter, and y is the reagent label;

[0064] A fully connected feedforward network is used to arrange neurons in rows and pass through the activation function. Compare the operation outputs;

[0065] σ k is the value of each activated neuron in the common layer, a k is the corresponding label in the activation of the output layer, and e is a constant;

[0066] Where the tan h function To calculate the paths with large differences in the characteristics of rice pests and diseases,

[0067] The Neuron is used as a computing node, which receives the signal of the photo sent back by the drone 19 in front and transmits the output backward after activation;

[0068] The activation function of the neural network needs to add a bias after the weighted sum, so the multiplication and addition operation and the threshold value are added into the activation function. middle;

[0069] Where b is the bias;

[0070] S4: If there is pest damage, the delivery pump 11 is turned on in time through the central control cabinet, and the medicine is delivered to the inside of each water support pipe 3 through the medicine delivery branch pipe 10, and finally sprayed out from the inside of the water spray bend 16. The water spray bend 16 rotates under the reverse force of the impact of the water flow while spraying the medicine, and the water support pipes 3 at the four corners can just fully cover the rice in the area through the water spray bend 16. The water spray bend 16 controls the servo electric cylinder 13 to extend and retract while spraying the medicine, allowing the adjustment lifting ring 602 to move up and down, and drives the installation rod 15 to pitch the water spray bend 16 up and down through the connecting rod 601 to adjust the angle and range of the spraying.
