Development and Application of UAVs
UAV is the abbreviation of unmanned aircraft. It is an unmanned aircraft operated by radio remote control equipment and its own program control device, or it is completely or intermittently and autonomously operated by an onboard computer. It is actually an unmanned aircraft.
UAVs first appeared in the 1920s and are mainly used in the military. But the early UAVs were only used as target drones, and the real reconnaissance aircraft for combat use was still after the 1970s. Due to its outstanding performance in the war, many countries have prioritized the development of unmanned reconnaissance aircraft since the late 1980s. They are racing to develop and equip unmanned reconnaissance aircraft, especially after the Gulf War. A boom in the development of unmanned reconnaissance aircraft.
With the development and advancement of technology in the electronics industry, people’s curiosity for exploring the unknown world has become stronger, people are studying more and more high-end electronic technology.And the application field of drones has also been broken. From the past pure military use to gradually Extend to civilians, police and households in multiple directions. Specifically, it has been involved in agricultural plant protection, aerial photography, environmental monitoring, power inspection, disaster relief, news reporting, express logistics, remote sensing mapping and other fields.
Now, follow me to understand the specific applications of drones:
Agricultural plant protection
UAVs are used as a flying platform, equipped with pesticide boxes, spraying equipment or testing equipment, to carry out pesticide spraying or data collection on farmland, which greatly improves the efficiency of pesticide spraying and the accuracy of CNC collection.
UAV aerial images have the advantages of high definition, large scale, small area, and high current status. They are especially suitable for obtaining aerial images of striped areas. Moreover, the drone provides convenient operation for aerial photography, and the take-off and landing are less restricted by the venue. It can be taken off and landed on playgrounds, highways or other relatively open ground, and its stability and safety are good, and it is very easy to transfer.
Environmental protection covers many areas, such as observing air, soil, vegetation, and water quality. Because drones are not restricted by space and terrain, they are effective, maneuverable, and have a wide range of inspections. Environmental protection workers can use the drone’s airborne image data collection function to monitor the overall travel of specific areas. Effectively collect high-pollution sources and carry out sorting measures.
Substations are usually located in remote areas, with harsh geographic conditions, a large number of equipment in the station, and a high degree of density. Due to the influence of climatic conditions and environmental factors, manual inspections are often time-consuming and inefficient. UAVs equipped with high-definition digital video cameras and cameras and GPS positioning systems can carry out positioning and autonomous cruises along the power grid, transmitting and shooting images in real time, and monitoring personnel can simultaneously watch and control them on the computer. Compared with manual line inspection, the efficiency is increased by 40 times.
When natural disasters such as mudslides, landslides, floods and other natural disasters occur in our lives, we need to know the disaster situation in time, but when it is difficult for rescuers to enter the disaster area, they can enter the disaster area through a drone, and analyze the disaster area through imaging. Disaster situation, fully understand the real-time information of the disaster, facilitate rescue work, make up for the lack of manual search and rescue, save a lot of manpower, and improve the search and rescue effect.
The participation of drones in urban traffic management can not only ensure the implementation of urban traffic development plans at the macro level, but also perform live monitoring and traffic flow control from the micro level, and build water, land and air three-dimensional traffic management to achieve regional control, ensure smooth traffic, and respond to sudden changes. Send time to implement emergency rescue.
In recent years, UAV distribution logistics has begun to be widely used worldwide, mainly to solve distribution problems in remote areas, improve distribution efficiency, and reduce labor costs.
Remote sensing mapping
UAVs can quickly obtain three-dimensional models and images of terrain surfaces through equipment such as orthophoto cameras, tilt cameras, photoelectric pods, and lidars, which can be used in national basic surveying and mapping, digital city construction, land and resources surveys, geological exploration, disaster emergency response Both have applications.
The application of drones in production and life is becoming more and more extensive. With the development of electronic technology, it is hoped that the development of the drone industry will bring greater and breakthrough applications in the future for the benefit of people!
