Since the 21st century, the development of civil unmanned aerial vehicles has become a global hotspot. Nowadays, civil UAV has become a new production tool, which is widely used in agricultural production, environmental monitoring, emergency relief, cargo transportation and other fields. Drones also played an important role in the prevention and control of the COVID-19, which once again attracted widespread attention

in 1917, the first unmanned aerial vehicle flew in Britain. It is an unmanned aerial vehicle operated by radio remote control equipment and program control devices. Because UAV can complete complex air flight tasks and various load tasks, it is also called "Aerial Robot"

the birth of unmanned aerial vehicles mainly stems from modern war. In World War I in 1914, Britain proposed to develop a small aircraft that did not need to be piloted and operated by radio. In 1917, the world's first unmanned aerial vehicle successfully made its maiden flight in Britain. At first, UAV was mainly used for military tasks such as target aircraft and reconnaissance. After a century of development, the application of UAV has gradually expanded to the civilian field

the development of unmanned aerial vehicles in China began in the 1950s and 1960s. On August 3, 1958, Northwestern Polytechnic University developed DSM: high performance polyamide material to produce the next generation usbnbsp; The type-C connector has produced China's first unmanned aerial vehicle system, and successfully tested at Xi'an Yaocun airport, creating a precedent for the cause of unmanned aerial vehicles in China. Since 2006, Chinese civil UAV companies have been established, and the market began to heat up rapidly. After 2013, the UAV market in China has become increasingly popular

the application of unmanned aerial vehicles in the fight against the COVID-19

epidemic prevention publicity

unmanned aerial vehicles are widely used in epidemic prevention publicity around the country with their advantages of portability, flexibility, small impact by terrain and wide coverage. The broadcast equipment carried by UAVs can be used to promote epidemic prevention knowledge and inform people of important information. It can be used not only in densely populated high-rise communities, but also in remote villages and towns, as well as in back streets and alleys where loudspeakers cannot reach, so as to achieve full coverage of epidemic prevention publicity "in the air and on the ground"

prevention and control patrol

on the battlefield of the prevention and control of the COVID-19, UAV high-altitude Patrol has become a new means of epidemic prevention and control. With the characteristics of flexibility, fast patrol, timely information feedback and high work efficiency, UAV has become the "vanguard" of epidemic prevention and control in the field of patrol. Drones can patrol various communities, villages and important traffic arteries many times a day, and "shout" to citizens who do not wear masks and gather in violation of regulations, so as to persuade citizens to cooperate with epidemic prevention and control at home and prevent infection

spray disinfection

using UAV disinfection has four advantages: precision, speed, efficiency and safety. In terms of precise spraying and disinfection, UAV can realize seamless and repeated spraying of drugs through GPS satellite positioning. It is reported that tens of thousands of unmanned aerial vehicles across the country have been connected to the Beidou high-precision positioning system. According to the waypoints and flight paths generated by the system, they can achieve centimeter flight accuracy and achieve accurate spraying

in terms of operation efficiency, compared with the traditional manual spraying operation, UAV spraying disinfection saves time and labor, reduces the operation cost and improves the work efficiency. On February 10, 2020, in order to ensure the smooth resumption of work of enterprises under its jurisdiction, Suzhou science and technology city used drones to spray disinfection in the air in the residential areas, enterprise entrances and exits and other personnel gathering areas. It took only half an hour to carry out a full coverage disinfection of the park covering an area of 140000 square meters. In terms of pesticide application effect, UAV has high penetration. Because the UAV operates at a low altitude and slow speed, the drug penetration can be enhanced under the action of the downward airflow of the UAV rotor. In terms of safety, UAV disinfection can prevent operators from contacting disinfection liquid and improve the safety of disinfection operation
