Prevent "illegal flight" ,to ensure low-altitude safety for the Guizhou Provincial Games



On August 18, the 11th Guizhou Games ended at the Liangdu Sports Center Gymnasium in Liupanshui, Guizhou. As the largest sports event with the highest specification and the largest number of participants in Guizhou Province, the Games has lasted 11 days since its opening on August 8, including a number of events in the two categories of competitive sports and mass competitions. The Liangdu Sports Center competition area successfully completed the prevention of the risk of drone "illegal flight" incidents by deploying a new measure of the drone control system, and ensured the low-altitude safety of the competition area.



Liupanshui Liangdu Sports Center is responsible for the opening and closing ceremonies and key events of the Games, with particularly strict security requirements. In order to prevent the potential threat of "illegal flying" incidents of drones and ensure public safety, the Zhongshan District Public Security Bureau of Liupanshui City finally selected our company's "TDOA grid drone control system" after multiple rounds of screening. 4 TDOA UAV detection equipment and 1 fixed UAV countermeasure equipment are deployed in the area where they are located, forming a "low-altitude protection network" with a sports center as the core area of more than 20 square kilometers, which can detect and warn in a timely and effective manner And dealt with several "illegal flying" incidents.



Our company's "TDOA Grid UAV Control System" adopts the design principles of standardization, platformization and openness, and has the characteristics of passive detection, full-time monitoring, unattended, etc. It can achieve the "flexible plan, remote early warning, identity recognition, precise positioning, real-time tracking, and rapid disposal" six in one full process control of low altitude UAVs, even in the face of multiple sorties Multiple types of UAVs can also be "visible, distinguishable and manageable", filling the gap in the field of UAV management and control of large-scale urban networking and fine governance in China.
For example, during the opening ceremony on August 8, two TV media UAVs that had been entered into the system's "white list" flew and filmed normally over the Sports Center without any impact. However, the "black flying" UAVs that tried to break into the airspace were detected by the system in a timely manner and were quickly countered and driven away, eliminating potential risks.



The surveillance and strike integrated vehicle mounted equipment, portable UAV detection equipment and countermeasures equipment also participated in the low altitude security of the Games. Based on technologies such as spectrum sensing and wireless voltage system, this vehicle borne UAV detection and countermeasure integrated equipment has the functions of detection and early warning, identification and rapid countermeasure for "illegal flight" UAVs, and its deployment and application are flexible and flexible. Liupanshui Municipal Public Security Bureau said that the vehicle mounted equipment, together with the portable UAV detection and countermeasure equipment, has effectively.
