What's the use of drones?

Unmanned Aerial Vehicle (UAV), abbreviated as UAV in English, is an unmanned aerial vehicle that is operated by radio remote control equipment and its own program control device, or operated by an airborne computer completely or intermittently. Compared with manned aircraft, drones are often more suitable for tasks that are too "stupid, dirty or dangerous". Uavs can be divided into military and civilian according to their application fields. On the military side, drones are divided into reconnaissance planes and target planes. In terms of civilian use, UAV+industrial application is the real demand of UAV; At present, its application in aerial photography, agriculture, plant protection, micro-selfie, express transportation, disaster relief, wildlife observation, infectious disease monitoring, surveying and mapping, news reporting, power inspection, disaster relief, film and television shooting, creating romance and other fields has greatly expanded the use of drones. Developed countries are also actively expanding their industrial applications and developing drone technology. 2065438+In September 2008, the 62nd meeting of the Harmonized System Committee (HSC) of the World Customs Organization decided to classify UAVs as "flying cameras".

App application

civil

In the police, urban management, agriculture, geology, meteorology, electric power, disaster relief, video shooting and other industries, drones are widely used.

Application field: working principle of power inspection: UAV is equipped with high-definition digital camera and camera and GPS positioning system, which can cruise autonomously along the power grid and transmit the photographed images in real time, and the monitoring personnel can watch and control them synchronously on the computer. Recommended reason: The traditional manual patrol mode is difficult and inefficient, and front-line patrol workers occasionally encounter the danger of being driven out by dogs and bitten by snakes. Unmanned aerial vehicle (UAV) has realized the electronic, informational and intelligent inspection, and improved the working efficiency, emergency rescue level and power supply reliability of power line inspection. In emergencies such as mountain torrents and earthquake disasters, the UAV can survey and urgently investigate the potential dangers of the line, such as the collapse of the tower foundation, which is completely unaffected by the road conditions, not only avoiding the pain of climbing the tower, but also surveying the visual dead angle of human eyes, which is very helpful for quickly restoring power supply.

Application field: Working principle of agricultural insurance: Using unmanned aerial vehicle (UAV) integrated with high-definition digital camera, spectrum analyzer, thermal infrared sensor and other equipment to fly on farmland, the planting area of insured land can be accurately measured. The collected data can be used to evaluate the risks and insurance rates of crops and determine the losses of affected farmland. In addition, the drone inspection also realized the monitoring of crops. Highlight: frequent natural disasters. In the face of the situation of no harvest, agricultural insurance is sometimes a lifeline for farmers, but it is difficult to claim compensation, which makes people more bitter. The application of UAV in the field of agricultural insurance can not only ensure the accuracy of loss determination and the efficiency of claim settlement, but also monitor the normal growth of crops and help farmers to take targeted measures to reduce risks and losses.

Application field: working principle of environmental protection: UAV can be roughly divided into three types in the field of environmental protection. 1. Environmental monitoring: observing the air, soil, vegetation and water quality, and at the same time tracking and monitoring the development of sudden environmental pollution incidents in real time; Second, environmental law enforcement: environmental supervision departments use drones equipped with collection and analysis equipment to cruise in specific areas, monitor the exhaust gas and wastewater emissions of enterprises and factories, and find pollution sources; Third, environmental treatment: using flexible wing UAV with catalyst and meteorological detection device to spray in the air, just like the working principle of UAV spraying pesticides, to eliminate smog in a certain area. Recommended reason: UAV can take aerial photography with strong durability, and can also use far infrared night shooting and other modes to realize all-weather aerial surveillance. UAV law enforcement is not limited by space and terrain. Strong timeliness, good mobility and wide inspection range, especially in the Beijing-Tianjin-Hebei region where smog is serious, which is convenient for law enforcement officers to check pollution sources in time and slow down the pollution degree of smog to a certain extent.

Application field: the working principle of film and television drama shooting: UAV is equipped with high-definition camera, and under the condition of wireless remote control, it can shoot from the air according to the needs of program shooting under remote control. Recommended reason: UAV has realized high-definition real-time transmission, with a distance of up to 5 kilometers, while the standard-definition transmission distance is as long as 10 kilometers; The drone is flexible, as low as one meter and as high as four or five kilometers. Can chase the car, can lift, can rotate left and right, and even can shoot at the horse belly, which greatly reduces the shooting cost. There are many successful cases of using drones in film and television circles. Whether it's the debut of new director Han Han, or the hit show "Where is Dad Going", or the classic Harry Potter series, the sky fell in 007, Transformers 4 and so on. Drones can be found behind the scenes. In addition, drones also contributed to the coverage of important events such as the Winter Olympics in Sochi, Russia and the Qiantang River Tide in CCTV.

Application field: How to confirm the right: From the territorial dispute between the two countries to the confirmation of rural land, drones can be used for aerial photography. Highlight: Take the Diaoyu Islands dispute as an example. The UAV is flexible, and can record Japanese devious moves around the Diaoyu Islands in China without dispatching a single soldier. In fact, in some countries, border confirmation involves different races, and sending drones to collect border data effectively avoids potential social conflicts.

Application field: Street view working principle: using unmanned aerial vehicles with shooting devices to carry out large-scale aerial photography to achieve the effect of aerial overlooking. Highlight: Both Google and Tencent have "Out" street views. Street view after street view pushes the road again and again. Maybe one day you and I will be photographed, but drones are very different. The street scenes they photographed not only have a bird's eye view of the world, but also have a little artistic flavor. Don't forget, when the remote sensing satellite is not bright enough in the area covered with fog all the year round, the drone will be charged.

Application field: the working principle of express delivery: UAV can deliver goods with the following sizes in shoe boxes, and the UAV can take off just by inputting the GPS address of the recipient into the system. Highlight: This is no longer a fantasy. Amazon in the United States and SF Express in China are busy testing this business, while Domino's Pizza Shop in the United States has successfully airlifted the first batch of pizza delivery in Britain. It is reported that Amazon claims that no one has a chance to deliver the goods to customers within 1.6 km within 30 minutes. It is said that the purpose of SF's development of drone delivery is to solve the problem of difficult delivery in remote areas. It is a very novel and good idea to send express delivery by drone, if it doesn't fall on the users. At least, it's a small surprise to send a ring with a drone at the wedding.

Application field: working principle of post-disaster rescue: using unmanned aerial vehicles equipped with high-definition shooting devices to take aerial photos of disaster areas and provide the latest first-hand images. Highlight: the drone moves fast. It took only 7 minutes to take off and land, and the aerial photography 100000 square kilometers has been completed, which is of great significance to the post-disaster rescue work against time. In addition, the UAV ensures the safety of rescue work, and avoids the dangerous areas where landslides may occur through aerial photography, which will provide valuable reference for rational allocation of rescue forces, determination of key disaster relief areas, selection of safe rescue routes and site selection for post-disaster reconstruction. In addition, drones can monitor the situation in the affected areas in real time and prevent the occurrence of secondary disasters. In fact, there are more than eight popular application fields of drones, including ten and twenty, and there are great advantages such as Jinying UAV mapping.

Application field: working principle of remote sensing mapping: First of all, remote sensing is remote sensing. Broadly speaking, you don't go to the target area and use remote control technology to inquire about the local situation. In a narrow sense, it is satellite pictures and flight pictures. Surveying and mapping remote sensing is the act of using remote sensing technology to calculate on the computer to achieve the purpose of surveying and mapping.

Used for military purposes

UAV has a wide range of uses, low cost and high efficiency; No risk of casualties; Strong viability, good mobility and convenient use. It plays an extremely important role in modern wars and has a broader prospect in the civil field.
