The invention discloses a disaster relief unmanned aerial vehicle path planning method based on an APF-IRRT fusion algorithm, and the method comprises the following steps: initializing parameters, expanding nodes, optimizing and smoothing a path, carrying out the smoothing of the path through cubic spline curve fitting or polynomial interpolation, and finally, carrying out the planning of a disaster relief unmanned aerial vehicle path. And outputting the optimized and smoothed flight path of the unmanned aerial vehicle by setting an algorithm termination condition. According to the disaster relief unmanned aerial vehicle path planning method based on the APF-IRRT fusion algorithm, the attraction force and the repulsive force are combined with adaptive step length and sampling angle optimization, the high efficiency of path planning and the obstacle avoidance safety are realized, and meanwhile, the smoothness and the performability of the path are improved through path smoothing processing; the method is suitable for efficient path planning of unmanned aerial vehicles in complex disaster relief environments.

The present invention discloses an underwater unmanned vehicle operation planning algorithm and system based on artificial intelligence, and relates to the technical field of underwater vehicles. The technical key points of the scheme are: the energy consumption factor is calculated by the speed and steering angle of the underwater unmanned vehicle relative to the water flow; the node with the smallest heuristic function value is selected as the current node, until the current node is the target node, and the shortest path is generated by backtracking; the angle between adjacent nodes is calculated by point product and vector length, and compared with the angle threshold to determine whether smoothing is required; for the smoothed path, the speed of the underwater unmanned vehicle is recorded, and the speed fluctuation coefficient of the underwater unmanned vehicle is calculated, and according to the speed fluctuation coefficient, the position and number of arc nodes are automatically adjusted by an artificial intelligence algorithm to optimize the path. The present invention can reduce energy consumption, extend the operation time, and improve the safety of the vehicle.

This invention discloses an intelligent grain silo sampling method and robot based on multi-point automatic planning, belonging to the field of grain silo sampling technology. The method involves a main control unit calculating and planning a compliant sampling point sequence and a global navigation path, supporting dynamic adjustment of the point sequence and replanning of the remaining path. Multimodal perception and obstacle avoidance algorithms enable autonomous robot navigation, obstacle detour, and path regression. Subsequently, grain surface perception, main control parameter adjustment, and resistance feedback complete adaptive sampling of the grain surface, and a unique identifier is generated for each grain sample. Finally, multi-dimensional data from the equipment and environment are collected throughout the process, and the main control unit determines anomalies, issues graded warnings, and responds to remote emergency commands, achieving full-process safety monitoring and emergency intervention. Using the above method and structure, precise sampling point planning, autonomous robot navigation and obstacle avoidance, adaptive grain surface sampling, traceable grain sample information, and full-process safety monitoring, early warning, and emergency intervention are achieved.

The utility model relates to the technical field of wax knives, in particular to a wax knife pen which comprises a pen holding rod and a knife head arranged at one end of the pen holding rod, the knife head is in a water drop shape and is detachably connected with the pen holding rod, an anti-skidding component is arranged on the middle lower portion of the pen holding rod, the bottom end of the knife head is in an arc shape, and the wax knife pen further comprises a knife holder. The tool bit is in the shape of the water drop, and the bottom end of the tool bit is in the shape of the arc with small radian, so that the tool bit is easier to use by a green hand during use, the tool bit is easier to touch the hand of the green hand during line drawing due to the fact that the radian of the bottom end of the tool bit is small, turning is easier, the tool bit is not prone to making contact with the hand of the green hand, and the tool bit is scalded due to the fact that the tool bit dipped in wax is thick. The use by green hands is more convenient.

The present invention provides a hood, comprising an outer air guide, a guide body, and an inner air guide; wherein the outer air guide cover is arranged on the upper outer side of the hood connecting pipe, and an upward exhaust passage is formed inside the outer air guide, and the guide body is supported on the outer air guide and is located in the exhaust passage; wherein the guide body is arranged on one side above the smoke exhaust port at the top of the hood connecting pipe, and the inner air guide extends upward along the upper end surface of the guide body, forming a side wall that can receive rebound wind or rainwater after falling to the inner wall of the outer air guide, and a drainage section that passes through the exhaust from top to bottom is formed between the side wall and the inner wall of the outer air guide; wherein the smoke discharged from the smoke exhaust port at the top of the hood connecting pipe is bent after passing through the guide body, and after passing through the drainage section, it is discharged from the top outlet of the outer air guide. The present invention can not only prevent the falling backflow of wind or rainwater, but also prevent the rebound backflow of wind or rainwater, and completely solve the backflow problem of the hood.

The application provides a humidifier. The humidifier comprises a casing, a water tank, a gauze, a water path assembly and a fan. The water path assembly can transmit water in the water tank to the gauze, so that the gauze is wetted. The airflow generated by the fan enters the airflow channel through the air inlet and is discharged through the air outlet. In the height direction of the casing, the projection of the air outlet and the projection of the gauze at least partially overlap. The airflow blows through the wetted gauze, the moisture in the gauze is vaporized, the airflow with the moisture flows along the airflow channel, and is discharged through the air outlet, so that the airflow stably and low-resistance flows, the airflow is reduced to turn in different directions, and the overall humidification efficiency can be improved.
