The present invention belongs to the technical field of unmanned aerial vehicles, and discloses a demonstration type of automated strike police intelligent rotor drone, which includes: a solar power supply module, a video monitoring module, a main control module, a wireless remote control module, an obstacle ranging module, a target locking module, a search and positioning module, a paint spraying module, a voice warning module, and a display module. The present invention has a simple structure and is easy to install through the obstacle ranging module, and the infrared light will not be affected by the surrounding environment such as visible light, and the sensitivity is also high, and it has strong universality; at the same time, through the search and positioning module, when searching with the unmanned aerial vehicle, after searching for the search target, the flight altitude of the unmanned aerial vehicle and the transmission power of the antenna on the unmanned aerial vehicle can be reduced, and the search target can be located in the reduced search area, thereby improving the accuracy of the obtained search position.

The invention provides a mine monitoring device based on an unmanned aerial vehicle remote sensing technology, and relates to an unmanned aerial vehicle, the mine monitoring device comprises the unmanned aerial vehicle, the two sides of the outer surface of the unmanned aerial vehicle are fixedly connected with fixing blocks, the two ends of each fixing block are fixedly connected with supports, and the bottom of each fixing block is fixedly connected with a frame rod; a connecting rod A is fixedly connected to the inner side wall of the frame rod, a supporting plate is fixedly connected to the upper surface of the connecting rod, and a supporting rod is fixedly connected to the bottom of the supporting plate. Through the arrangement of the adjusting assembly, the size of the unmanned aerial vehicle is small, when the monitoring device is driven, the weight of the unmanned aerial vehicle is increased, when the unmanned aerial vehicle flies, the flight height of the unmanned aerial vehicle is reduced, when the unmanned aerial vehicle flies, the range is reduced, and the monitoring result is influenced; therefore, the unmanned aerial vehicle flies downwind, the resistance during flight is reduced, the unmanned aerial vehicle flies higher, and the monitoring range is wider.

The present invention relates to an inverted trapezoidal wireless power transmission method supported by a drone, which belongs to the field of wireless power transmission and drone-assisted wireless communication, and comprises the following steps: S1: when wireless power transmission is performed in a blind area, the drone lowers its flight altitude and uses an inverted trapezoidal flight trajectory to charge a ground node; S2: constructing an energy consumption model of different flight postures of the drone; S3: jointly optimizing the hovering times m and the starting charging position (x B ,y B ), improve the energy receiving efficiency and fairness of the node, and ensure that the drone can return safely. The present invention adopts an inverted trapezoidal wireless power transmission method to reduce the flight altitude and transmission loss, thereby improving the energy receiving efficiency and fairness of the node while ensuring that the drone can safely reach the next base station to obtain energy replenishment.

The utility model discloses an outdoor search and rescue device based on laser radar and thermal imaging, which comprises a rack and a main control computer box fixedly arranged in the middle of the rack, four sides of the rack are fixedly provided with mounting racks, and the four mounting racks are fixedly provided with wing mechanisms for controlling the flight of the search and rescue device. According to the outdoor search and rescue device based on the laser radar and the thermal imaging, the laser radar is adopted for obstacle avoidance, all-weather obstacle avoidance can be achieved, the search and rescue efficiency is improved, and the search and rescue efficiency is improved. The problem that a traditional flight device cannot avoid obstacles at night or under the condition of insufficient light is solved, automatic flight of the unmanned aerial vehicle is achieved through Rviz map dotting, the professional ability requirement for rescue of the unmanned aerial vehicle can be further lowered, whether the unmanned aerial vehicle is a rescued target or not can be automatically recognized through a yov5 target detection method, and the rescue efficiency of the unmanned aerial vehicle is improved. Rescue errors caused by the fact that rescuers do not see the information are further reduced.

The present application relates to a kind of one-way swingable unmanned aerial vehicle strip sowing seed tube device of non-driven folding type, including strip sowing seed metering device connection device, normally closed electromagnet driven limiting device, rigid carbon fiber seed tube, flexible bellows, one-way swing assembly of fixed bellows and the roller of each joint connection place thereon.When unmanned aerial vehicle takes off, the gravity of seed tube itself is used to unfold without driving, and when unmanned aerial vehicle lands, the weight of fuselage is used to fold without driving.When operating, the upper end position of seed tube is fixed, the end can swing freely in one direction, and the length of seed tube can be set according to the size of rotor airflow.The present application has compact and ingenious structure, ensures the safety of unmanned aerial vehicle blind take-off and blind landing operation, realizes strip sowing operation in two seed dropping postures of seed tube end close to ground or trailing, and achieves the purpose of effectively inhibiting the interference of rotor airflow on falling seeds and the effect of seed large speed touch ground rebounding.
