Description

Control drone system {Drone system for extermination}

The technical field of the present invention relates to a control drone system, and in particular, to a control drone system implemented to prevent the separation of an undiluted solution in a drug container during drone spraying and to continuously maintain it in a liquid-mixed state.

Drones have been used for military purposes that perform missions such as aerial photography or aerial strikes through manual flight by remote control of ground control systems or autonomous flight using GPS. Due to the development of control technology using the control technology, it is not only used in fields such as high-altitude video or photo shooting and delivery, weather information collection, but also for decontamination, prevention of the spread of infectious diseases, agricultural use for spraying pesticides for pest control, high-rise buildings and It is used in various fields, such as fire suppression in deep mountains and performances to produce various performances in the sky.

Among the above-described drones, in the case of a control drone, it is possible to spray an appropriate amount of drug evenly while maintaining an appropriate altitude in a wide farmland. The pest control drone takes a method of combining the medicine bottle in a separate type, and takes a structure of spraying the drug downward, and has a leg structure corresponding to the foot at the bottom and a complicated structure such as a propeller structure for flight at the top. It is a tightly coupled structure.

This structure has the disadvantage of not being able to effectively control the drone because it is difficult to fly efficiently because the structure of the drone is caught on the branches of the fruit tree or the floor of the orchard in forest farms where fruit trees are opened. A drone with a more simple and mobile structure is required do. In the case of fruit trees, since most of the fruits are opened inside the tree, it is difficult to spray the drug directly to the fruit in the downward spray structure, and therefore, a drone to implement the upward spray function is required. In addition, it is necessary to improve the movement structure to prevent the drone from getting caught on the orchard floor.
