Abstract: Disclosed are a dynamic route planning method and device for unmanned ship used for feeding. The method includes: acquiring positioning information of a first set of vertices in a water body region, a feeding distance of a feeding device and positioning information of an unmanned ship; establishing a regional model according to the positioning information of the first set of vertices, and obtaining a route planning point according to the regional model and the feeding distance of the feeding device; obtaining a route target point according to the positioning information of the first set of vertices and the route planning point; dividing the route target point into an unreached target point or a reached target point according to the positioning information of the unmanned ship and the route target point; and obtaining a cruise route according to the positioning information of the unmanned ship and the unreached target point.

Abstract: A method and device for detecting water quality based on color recognition, and a storage medium. The method includes: collecting a water quality parameter sample and a RGB color parameter sample; normalizing the water quality parameter sample and the RGB color parameter sample; fitting a non-linear curve formed by RGB-PH values by using a RBF neural network model; establishing a RGB-water quality parameter lightweight database by using the non-linear curve of the RGB-water quality parameter; acquiring a color RGB value after a water sample to be detected reacts with a reagent; and comparing the color RGB value with the database to obtain a water quality detection parameter of the water sample to be detected.

Abstract: A developing device having a reduced size in the horizontal direction and in which a developing agent is transported with stirring along a circulating route inside a developing tank to effectively mix newly added toner therewith and stir the mixture. A developing tank for storing developing agent therein is horizontally divided with a partition member thereby providing an upper chamber and a lower chamber. A developer roller and a stirring roller are disposed in the lower chamber. Two screw rollers are disposed in the upper chamber. An inlet opening is formed between an end of the partition member and a regulating member for restricting a layer if the developing agent adsorbed to the developing roller. A developing agent removed by the restricting member is fed through an inlet opening to the screw rollers in the upper chamber. The developing agent is mixed with fresh toner supplied through a supply inlet and transported with being stirred by the screw roller in its axial direction.
