UAV interference system

  • 2016-06-29

With the popularity of the UAV, the interference of the normal operation of the airport more and more news. June 11, Warsaw, Poland International Airport occurred UAV interference airliner landing events; May 28, the Chengdu Shuangliu International Airport occurred UAV hinder the normal flight taking off and landing events, resulting in 55 flights delay...

According to incomplete statistics of the Chinese aircraft owners and Pilots Association, China's UAV has more than 20 thousand, but this is a very conservative estimate. Reporters from the big Jiang Tmall's flagship store has learned that since 2013, Tmall's sales on more than 70 thousand. However, the current holder of the drone pilot at the end of 2015 to 2142 people. In Ke Yubao opinion, although the entertainment level of the UAV driver does not necessarily need to have driving qualifications, but the relevant knowledge of the UAV operation is in urgent need of universal.

"Unmanned aerial vehicle (UAV) as part of aviation culture is need for us to promote the, even for entertainment, the driver should also understand the culture of aviation, to know where to fly, what place does not fly, the flight to comply with what kind of rules and regulations. We want to let the driver know that although the UAV is not manned, but its flight may pose a threat to other aircraft." Ke Yubao said.

Unmanned aircraft, referred to as unmanned aerial vehicles, which refers to the control of the unmanned aircraft by radio remote control equipment and control devices owned by the program. In recent years, with the domestic UAV industry show blowout type development trend, unmanned aerial vehicle (UAV) has been widely used in the field of traditional and non-traditional security, in addition to military application, also relates to many science research, agriculture, electricity, transportation, meteorology and other industries. Just a few years, development and application of the UAV has by a small minority to popular, especially in civil UAV application market, and even to the frenzied and abuse.

The rapid and disorderly development of UAV, its negative impact has been increasingly apparent! UAV "black fly" caused by security risks and accidents have been repeatedly reported and repeated. Some civilian UAV not only low prices, in addition to aerial photography function, even with the candid, steal book, listening, reconnaissance and drop items (containing contraband and dangerous goods) function, which gives the government agencies, the military restricted zones and key units to be confidential, prison guards, large sports meeting, large festivals, important figures in security, airports and airspace brought great security risks and management loopholes. For UAV use flooding, relevant regulatory measures, it is very difficult to implement, for UAV flying users and difficult to monitor the location and management. Therefore, for crime prevention UAV caused by security, leaks and other problems, without man-machine system or UAV interference against the potential of the system to be!

Without man-machine system or UAV interference countermeasure system theoretically speaking, the best implementation shall is: detection, interference, capture (landing). But due to the currently on the market most of little power machine has the advantages of small volume, remote control and data transmission, coupled with low altitude, low altitude flight, so whether it is the radar echo, optical image and audio analysis detection technology, will be because of the UAV body reflection signal is too small, near background noise disturbance, ground communication of complex signals high-rise buildings, obstacles, making of UAV detection can not do 100% recognition accuracy, false positive and false negative rate is extremely high. Under the existing detection technology is not yet perfect and reliable. The communication frequency of UAV remote control, positioning and data transmission of effective jamming, pressing, it is feasible and relatively safe and effective solutions.

Our (Nanjing Bai Kang Mechanical & Electrical Technology Co., Ltd.) has developed into use without man-machine system solutions, is the drone no fly zone and its surrounding a certain range, launch a number of standard interference signal, of UAV to all possible use wireless communication bands and suppress interference, including but not limited to: GPS positioning and navigation signal, compass generation, second generation Beidou, GLONASS (GLONASS), Galileo), 433MHz remote control, WIFI2.4G, WIFI5.8G etc.. UAV into the scope of the interference signal coverage, the performance of its performance as: lost contact, out of control, inertial flight, fall, etc..

If the system is equipped with GPS positioning induction generator, you can clearly define the scope of the no fly zone, and let the UAV close to the no fly zone lost contact with the remote control, UAV according to the location of the induced signal identification landing.
