The invention provides a live broadcast goods carrying scene optimization method and system combined with digital multimedia, and relates to the technical field of digital multimedia, and the method comprises the steps: firstly obtaining the cognitive association data of a live broadcast goods carrying scene, including the commodity cognitive multimedia content, the user cognitive behavior record and the commodity information set; then, based on the cognitive association data, establishing a corresponding relationship between the user cognitive behavior record and the commodity cognitive multimedia content, and generating a cognitive rhythm adaptation sequence; user cognitive behavior records and cognitive stage entries are matched in real time in live broadcast, and the commodity cognitive multimedia content is adjusted according to the adjustment rule parameter set; and collecting user subsequent behavior data during the adaptation period, adjusting the cognitive rhythm adaptation sequence after correlation analysis, generating a digital multimedia cognitive adaptation strategy, and applying the digital multimedia cognitive adaptation strategy to subsequent live broadcast. The live broadcast goods carrying effect and the user experience can be improved.

This invention relates to the field of next-generation livestock farming technology, specifically to a ventilated pigsty, comprising a pigsty body, a driver, a first cylinder, and a second cylinder. The first cylinder is equipped with a first piston, which is driven by the driver via a first piston rod. The first piston has a vent hole with a valve. The first cylinder and the second cylinder are connected by a one-way valve. The inner diameter of the second cylinder is smaller than that of the first cylinder, and there are multiple second cylinders. The second cylinder is equipped with a second piston, and an elastic element abuts against the end of the second cylinder away from the one-way valve. A filter cartridge is connected to the second cylinder, and the second cylinder and the filter cartridge are connected by a perforation. The filter cartridge is filled with deodorizing material and / or dust-removing material. An air outlet is provided at the end of the filter cartridge away from the perforation, and an air inlet is provided at the end of the first cylinder away from the one-way valve. This design ensures continuous ventilation while preventing odor leakage and continuously improving the air quality inside the pigsty.

This utility model belongs to the technical field of plastic extrusion equipment, and provides a material shortage alarm device for extruders based on photoelectric sensing. It includes a photoelectric sensing module comprising an infrared transmitter and a receiver installed on both sides of the feed inlet of the extruder hopper. The receiver detects changes in light intensity emitted by the infrared transmitter and converts them into electrical signals. At least one of the infrared transmitter and the receiver is inclined. Compared with existing technologies, the advantages of this utility model are that it uses non-contact photoelectric detection technology to avoid the problems of traditional mechanical wear, and the inclined installation facilitates the natural descent of materials by gravity, reducing blind spots. Combined with an external high-temperature resistant transparent protective cover with an anti-stick coating to prevent molten plastic from adhering and affecting light transmittance, the complementary structure of these two components improves the stability, environmental adaptability, and flexibility of the device's installation structure.
