As drones are gradually becoming popular, their market holdings are also increasing. After a great deal of popularity, drones also brought with it a series of safety issues. The situation of “black flying†has become increasingly severe. In view of this, in addition to policy supervision and standards, anti-drug technology has also become a powerful "weapon" to curb "black flying."
Containing the "black fly" has a new move to reverse the UAS or become a "creeper"
In recent years, with the continuous reduction in the price of consumer drones, and the ease of operation, coupled with the small size, drones have quickly moved from cutting-edge military equipment to the mass market, becoming a toy for many aerial players, and the drone market. The number of holdings continues to rise. However, due to lagging drone management regulations, some drones have weak security awareness, and unmanned aerial vehicles have frequent "black fly" incidents.
The "black flying" drones not only interfere with aviation safety, but also pose a threat to public safety and personal privacy. In the first half of this year alone, the CAAC received 44 reports of drone-impacted flight operations, an increase of 37 cases over the same period of the previous year. The number of affected flights was 790, an increase of 689 classes over the same period last year.
Drone "black fly" situation is increasingly serious
"The unmanned aerial vehicle's "black fly" has a great impact on flight safety." Liu Shiqian, an associate researcher at Shanghai Jiaotong University's School of Aeronautics and Astronautics, said, "Drone drones do not have their own fixed flight routes, so it is very difficult for civil aviation pilots to make further renewal. The judging of flying will generally return for flight safety, which will bring losses to the country and civil aviation.â€
According to statistics, from mid-January to mid-February 2017, there were 12 incidents involving the illegal operation of unmanned aerial vehicles that threatened civil aviation safety; only from 2 p.m. to 5 p.m. on April 21, there were three unmanned vehicles at Chengdu Shuangliu Airport. Flight disruption led directly to the flight of 58 flights, four flights returning, 100% flight delays, and more than 10,000 passengers stranded.
In addition, drones interfered with civil aviation incidents at airports including Nanjing, Chongqing, and Wuhan. The drone interference also caused flights to drop or delay. At the same time, the damage caused by unmanned aerial vehicles (UAVs) malfunction or accidental fall has also been reported to the press, and even worse, criminals have used drones to make photo shoots, threatening personal privacy and national security.
Regulatory policies and industry standards accelerated
In the face of the “black fly†unmanned aerial vehicle that has repeatedly been banned, the government has begun to strengthen supervision and has successively introduced a series of drone policies and industry standards to accelerate the improvement of drone management systems.
In May, the Civil Aviation Administration issued the real-name policy for drones, which has been in effect since June 1. The real-name system policy stipulates that all private drones with more than 250 grams must be registered with the real name. If the drone owner flies outside, he must also apply to the relevant department for approval and he must have a drone driver's license.
In addition, the CAAC also issued two industry standards, "UAV Drone Fence" and "Drone Cloud System Interface Data Specification." The standard defines the scope, configuration, data structure, performance requirements, and testing of drone fencing. Requirements, etc., and classification of drone enclosures. At the same time, the "Drone Cloud System Interface Data Specification" specifies for the first time the data requirements, data encryption requirements, coding rules, and performance requirements for light and small civilian UAV systems and UAV cloud systems.
The anti-UAV system has become a powerful means to deal with "black fly"
In the face of the potential security risks brought by the rapid development of drones, the anti-drug industry has gradually emerged. The use of anti-drone technology to counter "black fly" drones has become a more effective and rapid means of disposal.
A few days ago, the nation’s first airport "drone detection and defense system" was put into trial operation at Baiyun Airport. It is understood that the system can be discovered and accurately located within 3 seconds after the drone is turned on, and precision electromagnetic interference is implemented to achieve drone removal and forced landing within the prevention and control area. The detection range reaches 13 kilometers in diameter.
According to Baiyun Airport technicians, the "defense detection and warning system" determines the position of the drone by receiving drone image transmission and remote control signals, and can be found and accurately located within 3 seconds after the drone is powered on; "Human-computer interference system" is used to automatically adjust the frequency and direction of electromagnetic interference. According to the detected information such as the working frequency and direction of the drone, precise electromagnetic interference is implemented to achieve drone removal and forced landing in the prevention and control area.
In addition, it is worth noting that according to the analysis and assessment conducted by the Second Institute of the Civil Aviation Administration, the UAV jamming equipment of the Cangwu system has basically no effect on the normal operation of the airport equipment, the guiding equipment and the airborne equipment.
It can be seen that, in addition to strengthening supervision through the introduction of policies and improving standards to promote industry standards, the continuous development of anti-UAV technology will also provide a strong support for the establishment of a mature drone control system, so as to better promote the entire drone. The sustainable development of the field.
