The invention relates to the technical field of advertising sign production, and discloses an advertising sign production-based engraving device which comprises a tabletop and a laser engraving machine, a processing groove is formed in the top of the tabletop, four electric suction cups are mounted on the inner wall of the bottom of the processing groove, and two first sliding rails are arranged at the top of the tabletop; a first linear motor is arranged at the top of the first sliding rail, through mutual cooperation of a transmission shaft, a first arc plate, a second arc plate, dust-free cloth and bristles, a carbonized layer generated by laser engraving can be scraped off and erased while the laser engraving machine engraves a plastic advertising sign, and the laser engraving machine is convenient to use. The curved plate and the balls are arranged, so that the dust-free cloth and the bristles move back and forth repeatedly in the rotating cleaning process, continuous and uniform friction force is generated among the dust-free cloth, the bristles and the carbonized layer, and the carbonized layer can be more effectively stripped from the plastic surface through the repeated scraping action.

The invention discloses a patient state identification information pushing system and method for a smart ward, and belongs to the technical field of video engines, and the system comprises a video display module, a buffer area adjustment module, a code rate initial adjustment module and a code rate secondary adjustment module. Wherein the video display module is used for obtaining a video fluency index so as to obtain a video fluency judgment result; the buffer area adjusting module obtains a network congestion state judgment result, analyzes and obtains a buffer area adjusting judgment result in combination with a video fluency judgment result, and adjusts the size of a buffer area; the code rate initial adjustment module is used for analyzing and obtaining a code rate adjustment judgment result based on the size of the adjusted buffer area so as to carry out corresponding code rate adjustment; and the code rate secondary adjustment module is used for acquiring and analyzing the video fluency index after code rate adjustment, thereby performing corresponding secondary adjustment on the initial code rate, and solving the problem that video fluency and definition cannot be both considered in the prior art.

The present invention discloses a method and system for intelligent perception of thermal images based on coal gangue migration situation, belonging to the technical field of intelligent mining of coal mines. The method solves the problems of poor image contrast and low clarity by performing data enhancement processing on the image; trains the coal gangue detection model through data in a laboratory simulation environment, verifies the effect of the model through a laboratory simulation environment, and puts the verified model into practical use to improve the accuracy of the model; uses the verified model to detect the target, obtains the detection frame corresponding to the target, obtains the average temperature of coal and gangue according to the detection frame, and then obtains the temperature data points of coal and gangue according to the average temperature, thereby calculating the mixed gangue rate; due to the high accuracy of the coal gangue target detection model, the detection frame corresponding to the target can be accurately obtained, and the average temperature of the target can be accurately obtained according to the detection frame; at the same time, the mixed gangue rate is accurately calculated by counting the number of temperature data points.
