Core Viewpoint - The 17th China International Modern Railway Technology Equipment Exhibition highlighted the growing concern over the safety threats posed by unauthorized drones to railway operations, emphasizing the need for effective regulation and monitoring of drone activities [1][2]. Group 1: Exhibition Overview - The exhibition took place from July 7 to 9, covering an area of 40,000 square meters and showcasing the latest advancements in ten specialized sectors including locomotives, communication signals, passenger and freight transport, and safety assurance [1]. - A significant focus of the event was on the potential threats posed by unauthorized drones, particularly their impact on public transportation safety, especially railways [1]. Group 2: Drone Detection and Countermeasures - A drone monitoring and countermeasure equipment designed for complex railway environments attracted considerable attention, developed by Zhongke Lanzhuo, a specialized small and medium-sized enterprise in Beijing [1]. - The equipment features advanced integrated industrial design and spectrum detection technology, capable of detecting drones within a radius of 2 to 6 kilometers, addressing typical protective needs along railway lines [1]. Group 3: Technical Highlights - The drone monitoring equipment is noted for its deployment flexibility and collaborative capabilities, allowing for quick setup and independent operation to detect and identify suspicious drones [2]. - When multiple units are networked, the system can accurately locate and track the trajectory of intruding drones and employ various countermeasures, including forced landing and guiding unauthorized drones back to their original flight paths [2]. - The system also utilizes wireless positioning technology to trace the operator's location, providing technical support for subsequent legal actions and accountability [2]. Group 4: National Security Context - The construction of a safety control system for low-altitude economy has become a crucial part of national security strategy, highlighting the importance of ensuring safety in low-altitude airspace with the increasing use of drones and other new flying vehicles [2].
