Description

Technical Field

[0002] Plant diseases and insect pests are a general term for plant diseases and plant pests, that is, under the influence of biological or non-biological factors, plants undergo a series of morphological, physiological and biochemical pathological changes, which hinder the normal growth and development of plants. Plant diseases and insect pests can cause many kinds of harm to plants, such as affecting plant growth and development, causing a decrease in plant yield and quality, and destroying the ecological balance. Therefore, the prevention and control of plant diseases and insect pests is a very important step in the plant cultivation process. Different types of plant diseases and insect pests will use different measures in the process of control. Therefore, before controlling plant diseases and insect pests, it is necessary to detect and diagnose the types of plant diseases and insect pests.

[0003] Traditional manual detection methods mainly rely on farmers or agricultural technicians to rely on experience and visual observation to determine whether plants are infested by pests and diseases. This method is not only time-consuming and labor-intensive, but also inefficient and difficult to adapt to the development needs of large-scale and industrialized modern agriculture. With the development of detection technology, hyperspectral imaging instruments are currently used in the detection of plant pests and diseases to reflect the changes in the spectral characteristics of plants, thereby quickly and accurately diagnosing and detecting plant pests and diseases. Hyperspectral imagers have certain requirements for the detection environment, and lighting conditions have a greater impact on hyperspectral imaging. In order to obtain stable and reliable spectral data, the hyperspectral imager is usually shielded by the box shell.

At this time, the electromagnet 16 is disconnected from the battery 22, and the electromagnet 16 loses its magnetic force, while the lower box 3 continues to rise. After the lower box 3 is engaged with the upper box 4, the lower box 3 drives the first contact 17 to connect with the third contact 21. The magnetic pole direction of the electromagnet 16 formed by the third contact 21 repels the magnetic pole of the lower magnetic block 14. Under the action of the repulsive magnetic force, the support cylinder 11 rotates in one direction under the support of the one-way bearing 12, thereby driving the stage 10 to rotate 180 degrees, so that the plant sample originally located on the lower surface of the stage 10 rotates to the upper surface for sample testing. At this time, another sample to be tested can be placed on the surface of the sample injection plate 29 and moved to the bottom of the stage 10, and the electric push rod 23 is started. , the electric push rod 23 drives the lower box 3 to descend, so that the first contact 17 is separated from the third contact 21 and contacts the second contact 20 again. At this time, the magnetic pole direction of the electromagnet 16 is attracted to the magnetic pole of the lower magnetic block 14. Since the lower magnetic block 14 rotates upward with the support tube 11, the magnetic poles of the upper magnetic block 13 and the electromagnet 16 in the lower half of the support tube 11 repel each other. Under the action of the magnetic force, the stage 10 is flipped again, thereby realizing the position switching of the plant sample.

[0031] Working principle: Use the sample inlet plate 29 to deliver the plant sample to the bottom of the stage 10, start the sample suction structure inside the stage 10, use the air outlet pipe 25 to absorb the plant sample, and absorb the plant sample on the surface of the support plate 24 below. Use the electric push rod 23 to drive the lower box 3 to rise and fall. As the lower box 3 rises and falls, the No. 1 contact 17 on the outer surface of the lower box 3 contacts the No. 2 contact 20 and the No. 3 contact 21 in turn, thereby changing the magnetic pole of the electromagnet 16, and using the magnetic force of the electromagnet 16 to realize the flipping of the stage 10. Use the flipped stage 10 to drive the plant sample on the surface to flip. At this time, the upper box 4 and the lower box 3 are combined to form a closed space, and the hyperspectral imager 7 is started to collect spectral data of the plant samples on the stage 10. By analyzing the changes in the characteristics of the plant reflection spectrum, it is determined whether the plant is suffering from pests and diseases and the type and degree of the pests and diseases.

[0032] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
