Military drones were the initial purpose of developing drones. Around 2000, civil drones gradually scaled up, driven by the market. In the early days, Japan's agricultural drones and forest drones were typical representatives, and they were mainly medium-sized rotor or fixed-wing airframes.

Over the next decade, more and more individual players became interested in small aircraft and turned it into a high-end competitive activity, which laid a good user base for the later rise of small civilian drones. China's small civilian drone industry has also started and prospered against this background.

Around 2007, a small number of enterprises in China began to develop civilian drones. At the time, most of the civilian drones used single-rotor helicopters, and the operators still needed a lot of training to work. Around 2010, the emergence of the quad-rotor aircraft body broke this situation. Around 2011, the aerial photography market first began to accept this method, and later developed to the stage where ordinary consumers can also play aerial photography. In the past two years, the civilian drone industry has been exploring more applications, and the entire industry has begun to explode.

China started early in the civilian drone industry. More and more domestic industrial capital and technical forces are participating in the civilian drone industry, making the industry cake bigger and bigger. One of the members of the drone manufacturer MMC In the industry of industrial drones, there should be for development, has been at the forefront of the industry. Facing global competitors, how to maintain our advantage? I think this requires continuous technical innovation. This technological innovation is not only commercialization of existing technologies at home and abroad but also a forward-looking study on basic technical issues facing future industrial applications. Only with layered and planned technological innovation around the civilian drone industry can a stable industrial cluster be formed.

In fact, there are many possibilities on the road for the expansion of civilian drones to more industries. How to extract useful information from a large amount of data collected by airborne equipment is the main technical issue affecting its further application. Taking a national science and technology support project led by the State Administration of Cultural Heritage of China as an example, the use of a small drone's airborne lidar system to study the 3D modeling technology of the Great Wall of China in the Ming Dynasty has subverted the traditional large-scale scene culture Heritage monitoring methods to help archeologists quantitatively preserve and analyze the morphological changes of the Ming Great Wall. This technology has made breakthrough progress so far and has been successfully demonstrated in Yulin and other places along the Great Wall.

As more and more small drones appear in the urban sky, their security issues have become increasingly prominent. In addition, with the continuous expansion of civilian drone application scenarios, drone control systems will receive more and more complex tasks, and the safety and reliability of their software systems are facing great challenges. At present, the limited load capacity of civil drones determines that the capacity of the onboard processor cannot carry a huge safety software system, so it is necessary to study how to use a minimum flight control system with safety to ensure the correct operation of each part.
