Advanced Airport Bird Deterrent: Phased Array Acoustic & Pulse Technology
Bird strikes are a critical safety and economic threat to the aviation industry, causing millions in damage and endangering lives every year. While keeping birds away from runways and taxiways is essential, airports face a unique challenge: they cannot use loud, omnidirectional noise devices that would disturb nearby residential communities. Traditional methods like spikes or standard ultrasonic devices also fail quickly as birds adapt. The DH-E510, a specialized airport bird deterrent, solves this dilemma by combining high-energy directional acoustics with a safe high-voltage micro-pulse, delivering a silent, dual-sensory defense.
Directional Acoustics: Zero Noise Pollution The core of this airport bird deterrent is its phased array acoustic technology. Unlike standard speakers that broadcast sound in all directions, the DH-E510 focuses acoustic energy tightly forward. At a distance of one meter, the sound pressure level reaches an impressive ≥130dB, with an effective deterrence range of 10 to 80 meters. Crucially, the sound decays rapidly behind and to the sides of the device, ensuring zero noise disturbance to surrounding neighborhoods, terminals, or air traffic control towers.
Dual-Sensory Deterrence: Sound and Touch If birds venture into the highly restricted zones, the system activates its second layer of defense: a high-voltage micro-pulse. The voltage is adaptively regulated between 5kV and 10kV, but the energy is strictly limited to <0.1J per pulse. This adheres to international animal protection standards, delivering a strong tactile warning without causing physical harm. By combining the auditory scare with a physical touch, the system creates a deep "fear memory" in birds, preventing habituation and ensuring they do not return to the flight paths.
AI Dual-Sensor Detection To prevent false alarms and conserve energy, the DH-E510 features an AI dual-sensor perception system. It integrates millimeter-wave radar with a PIR (Passive Infrared) thermal release sensor. The deterrence system only activates when both a moving object and a heat source are detected simultaneously. This intelligent filtering effectively ignores wind-blown debris, rain, and leaves, significantly reducing power consumption and extending battery life during overcast days.
Rugged and Autonomous Operation Built for the harsh, open environment of airfields, the device features an IP66 weatherproof rating and operates reliably in extreme temperatures from -20°C to +85°C. It is powered by a solar panel and battery, ensuring continuous operation even in remote locations. Data and status updates are transmitted via a 4G communication interface, allowing airport operators to monitor the system's health and adjust parameters remotely.
Why It Matters for Aviation Safety By merging directional acoustics with safe tactile pulses, the DH-E510 provides a sustainable, eco-friendly, and highly effective solution for runway safety. It eliminates the risk of bird strikes, reduces wildlife management costs, and ensures that critical aviation infrastructure operates without interruption.
