Statistics show that there are more than 12,000 drone companies in China in 2021, with a total industry output value of 87 billion yuan. my country's low-altitude airspace management reform is being piloted in many provinces, and the urban "low-altitude sky road" network is being built to support the large-scale commercial development of drone applications. The low-altitude economy represented by drones is expected to become a new driving force for social and economic growth. engine. Relevant experts suggested that we should focus on supporting a group of leading drone logistics companies and increase efforts to release low-altitude airspace resources.
The sharp increase in drones, the safety supervision system needs to be upgraded
According to reports, my country has established 13 pilot areas for drone development, of which two are pilot areas for drone logistics development and three are pilot areas for urban drone logistics and distribution. Yang Jincai, academician of the European Academy of Sciences and executive chairman of the World Drone Conference, said that in the past two years, drones have achieved a rapid growth of 30% due to the development of new formats such as contactless distribution and intelligent applications. And other products have been widely used, and it is expected that the output value of the domestic drone industry will exceed 100 billion yuan this year.
The sharp increase in the use of consumer drones makes the healthy and sustainable development of civil drone systems and the scientific supervision of drones more and more important. Jiang Huajing, chairman of Shanghai Tejin, said that the regulatory system that adapts to the development of drones needs to adopt the design principles of standardization, platformization and openness, breaking through the "single-point defense, independent operation, and extensive attack" in traditional drone security management and control. Limitations, and ultimately realize the full-time monitoring, unattended, data fusion and precise prevention and control of low-altitude UAVs in the context of smart cities.

At the venue, the "UAV control and command vehicle" jointly developed by Tekin and GAC aroused the interest of the participants. According to reports, the command vehicle has been used in the supervision practice of low-altitude UAVs. It is equipped with UAV detection and counterintegration equipment and a management and control platform system. UAV's detection and early warning, identification and rapid countermeasure functions, the safety control radius in urban environment can reach 1-3 kilometers.

In addition, the duty personnel can be equipped with "portable UAV detection and direction finding equipment" at the same time. On the basis of UAV detection, identification and early warning functions, the UAV direction finding function is added, which is convenient for daily flexible UAVs. Prevention and control operations.
New racing drones challenge detection and countermeasures
In recent years, with the development of the drone industry and the maturity of the professionalism of drone enthusiasts, some self-made drones have reached the level of racing. A UAV called "traversing aircraft" in the industry has a racing nature but lacks the necessary safety guarantee system, which has become the focus and difficulty of monitoring.
The detection and discovery of the self-made traversing machine is an industry problem. Because the signal is relatively weak and the signal characteristics are not obvious, the self-made traversing machine is easily submerged in the ambient radio noise and difficult to be detected effectively, which brings great challenges to the daily supervision work. "We combine UAV spectrum signal sensing with TDOA time difference positioning technology, which can quickly and accurately locate and track the self-made traversing aircraft in real time, providing strong technical support for security." Jiang Huajing said that the traversing aircraft is a kind of high-speed, high-speed The maneuverable multi-rotor aircraft can reach a speed of more than 200 kilometers per hour. At present, most of the time-travel aircraft on the market are DIY (self-made) types. Players mainly purchase accessories and assemble the aircraft themselves. They lack a complete flight control system and GPS positioning system. It is highly dependent on the pilot's control skills. once it loses control in flight, it is very easy to cause a high-speed crash. Moreover, it is not restricted by the electronic fence, and there are security loopholes that can be used by criminals to secretly take pictures, steal secrets, and carry dangerous goods.anti drone laser system

This World UAV Conference conducted extensive discussions on the planning and construction of low-altitude airway networks and issued the "Sky Road Declaration". "To develop the low-altitude economy, low-altitude opening is an inevitable trend." Jiang Huajing believes that while building a "low-altitude sky road network", it is necessary to carry out the simultaneous construction of the network's security infrastructure, and realize the implementation of fine supervision of urban low-altitude airspace.
