This invention provides a rotating charging device for use in automated parking garages. The charging device includes a charging unit, a swing arm unit, a rotation drive unit, a position detection unit, and a control unit. The charging unit is connected to one end of the swing arm unit, and the rotation drive unit is connected to the other end of the swing arm unit. The rotation drive unit is fixed to a mounting base, which is installed on one side of a vehicle carrier tray. The position detection unit and the rotation drive unit are electrically connected to the control unit. The position detection unit detects the location of the vehicle's charging port and transmits the detected position signal to the control unit. The control unit stores the correspondence between the charging unit's position information and the target charging position, thereby driving the swing arm unit to rotate in a horizontal or vertical plane, automatically switching the charging unit to the target charging position corresponding to the charging port. This adapts to the differences in charging port positions for different vehicle models, improving the device's applicability.

This invention relates to a plant antagonist and its application. The main active ingredient of the plant antagonist is methyl ferulic acid, with an effective concentration of 0.05 μg / mL to 0.5 μg / mL. This invention also discloses the application of this plant antagonist in the control of diseases in fruit trees and fruits, including apples, pears, grapes, and tomatoes, and diseases including ring rot, anthracnose, and gray mold. The plant antagonist of this invention can comprehensively activate the plant immune system, simultaneously inducing a significant increase in the activity of multiple disease resistance-related enzymes (such as peroxidase, polyphenol oxidase, and glutathione S-transferase) in the plant, and upregulating multiple disease resistance-related PR genes (such as...). MdPR1 , MdPR2 The expression of [various substances] systematically enhances the innate immunity and acquired resistance of plants, achieving multi-pathway synergistic defense. This inducer works by stimulating the plant's own disease resistance mechanisms, reducing dependence on chemical pesticides and lowering the risk of pesticide residues, which aligns with the direction of green and sustainable agricultural development.
