    摘要： A method for extracting pullulan polysaccharide from high-viscosity fermentation broth includes following steps: (1) removing cells from the fermentation broth; (2) removing proteins; (3) decolorizing by macroporous resin adsorption; (4) removing ions by ultrafiltration; and (5) drying, crushing and packaging. In the extraction method of the present application, by using natural polymer bioflocculant chitosan, the high-viscosity fermentation broth can be processed without dilution and addition of filter aids and organic solvents for alcohol precipitation, which reduces the pressure of subsequent decolorization, properly recycles the cell proteins, and avoids the potential hazard of the organic solvents. The method can obtain high-purity pullulan polysaccharide, improving the product yield and quality, reducing solid waste, reducing the production cost, and achieving a safe, efficient, continuous and automated production process.

    摘要： Disclosed is an unmanned aerial vehicle (UAV) positioning method based on a millimeter-wave radar, including a calibration stage and a positioning stage. The calibration stage includes: acquiring ground coordinates of the unmanned aerial vehicle; and extracting feature points from radar point cloud data and get the ground coordinates of the feature points. The positioning stage includes: acquiring radar point cloud data of a current frame and pre-processing; acquiring UAV motion data and fuse the data with radar point cloud data; extracting characteristic line segment from radar point cloud data; registering the characteristic line segment of the current frame with the characteristic line segment of the previous frame, and finding matching feature points and newly added feature points; and obtaining the ground coordinates of UAV and the ground coordinates of newly added feature points based on the ground coordinates of matched feature points on the map.

    摘要： Disclosed are an LED cabinet and an LED display including the LED cabinet. The LED cabinet includes a cabinet body provided with at least one mounting area for mounting LED display modules, the mounting area is provided with at least one cabinet magnetic members and a helper disassembly handle, which is movable relative to the mounting area to generate thrust to separate the LED display module from the cabinet body. The LED display includes the LED cabinet and at least one LED display module mounted on the LED cabinet, the LED display module is provided with at least one module magnetic member corresponding to at least one cabinet. When the LED display module is disassembled, the helper disassembly handle is driven to move to generate thrust to push the LED display module, so that the LED display module separate from the cabinet body of the LED cabinet.
