[0040] Principle: The present invention is a device based on the scientific integration of drones and UVC-LED deep ultraviolet (275nm wavelength) sterilization modules, which consists of a drone body 1, a brushless motor, a flight camera 2, a battery, a rotor device 12, a flight control system, a gyroscope module, various sensors such as front visual sensors, bottom visual sensors, side visual sensors and ultrasonic sensors, a UVC-LED light source 17, an electrically adjustable UVC-LED drive circuit and a heat dissipation module (the flight control system of a drone is the flight control system of a drone. The gyroscope (flight attitude perception) and the accelerometer can monitor the attitude of the aircraft, thereby achieving stable flight, which is the most critical part of automatic flight.). The front and bottom of the drone are also equipped with lighting LED lights 15 and warning lights 16, which can form light in lightless space areas. The drone can achieve full-domain flight and perform comprehensive public health disinfection tasks. UVC-LED light source modules are dispersedly placed on the four rotors of the drone, and several UVC-LED light source modules are placed on the upper surface of each rotor. Similarly, corresponding UVC-LED light source modules are symmetrically placed on the lower surface of the corresponding rotor (the drone can be used to disinfect the upper and lower spaces of the place). Placing them on the rotor surface is conducive to increasing the deep ultraviolet illumination range and illumination uniformity. The principle of the present invention designing that the UVC-LED light source module is placed on each rotor is to disperse the heat source. In addition, the airflow generated by the rotor helps to dissipate heat. Various sensors can ensure that the drone carries out a safe flight trajectory and performs accurate public health disinfection tasks. The present invention sets the drone wheelbase to 600mm (industrial applications can be increased or decreased as needed), the optical power of each light source module is 1000mw, and the drone is equipped with aircraft batteries and various flight control systems. The present invention is suitable for surface disinfection of key locations in public places, without toxic side effects and odor residues, without human participation, and can be disinfected in indoor environments such as shopping malls, subways, and airports, and can achieve long-term work. Flight path planning enables the coordinated operation of multiple drones, thereby disinfecting the entire space without blind spots.

[0041] In the event of an outbreak of an infectious disease, the aircraft can be remotely controlled to quickly enter spaces where high-risk viruses may exist at any time for disinfection. It can also be used for daily preventive disinfection and security monitoring of these places, and to assist manual inspections of hidden dangers in related facilities. The device of the present invention is a more efficient and energy-saving way to disinfect and sterilize spaces in public places. With the improvement of photoelectric conversion efficiency and the increase in drone battery power, combined with the application of wireless charging technology, the efficiency of disinfection and sterilization can be further improved. In addition, while sterilizing, drones can also perform part-time security monitoring and assist manual inspections of hidden dangers in carriages and railway facilities. It is of great significance to the field of public health, and the device of the present invention can also be used in public environments such as medicine, food, and cosmetics that have disinfection requirements for the production environment.

[0043] 1. Turn on the power of the drone and check whether there are any abnormalities in each module of the machine;
