Along the steel corridors where high-speed trains race, birds—though seemingly graceful—pose the number one threat to rail safety. The complex structure of overhead contact lines is often mistaken by birds as an ideal nesting spot, and the resulting falling nesting materials or droppings can easily trigger flashovers and circuit trips. To address this critical issue, Shenzhen Zhenqu Bird Technology has introduced the ZQN-TL-DXRailway-Specific Directional Acoustic Bird Deterrent. With its intelligent design and high-performance deterrence capabilities, it has become a powerful technological tool for railway maintenance and power supply departments.
I. Dual-Radar Monitoring
The ZQN-TL-DX railway-specific directional acoustic bird deterrent avoids "blind operation" by utilizing two built-in high-precision radar units to detect bird activity in the surrounding area in real time. As soon as a bird flaps its wings and enters the preset warning zone, the system activates instantly, ensuring that potential hazards are intercepted before they can cause damage.
II. 120-decibel high-intensity sound waves
The core principle of the railway-specific directional acoustic bird deterrent is a dual approach combining physical and psychological deterrence: High-intensity sound: Using built-in specialized speakers, the device emits directional, high-intensity sound waves across a broad frequency range of 2 kHz to 25 kHz. Deterrence range: At sound pressure levels as high as 120 decibels, the auditory nerves of birds within a 35-meter radius are severely disrupted. This "unbearably piercing" sound environment forces birds to abandon their perches and fly away voluntarily.
III. Deceptive Deterrence
Precise Simulation of Predators and Danger Signals: In addition to pure noise suppression, this device incorporates an intelligent sound library. It can accurately mimic the screeches of birds of prey, such as eagles, or realistically reproduce the sound of firecrackers exploding. By triggering birds’ deep-rooted instinctive fear, the device psychologically discourages them from nesting, thereby significantly increasing the success rate of deterrence.
IV. Minimalist Operations
Remote Control and Long-Lasting Battery Life: To adapt to the complex outdoor environments along railway lines, the ZQN-TL-DX has undergone extensive optimization in terms of operation and power management: Remote Control: Supports wireless remote control within a 15-meter range, allowing maintenance personnel to quickly switch device states or perform functional tests from the ground. It employs a green power solution combining solar panels and a high-capacity battery. The system efficiently stores energy on sunny days and relies on stored power to maintain continuous operation during cloudy or rainy weather, truly achieving maintenance-free, long-term, and stable outdoor operation.
In operation, the ZQN-TL-DXDirectional Acoustic Bird Deterrent uses sound as a shield, transforming the intangible into the tangible. Not only does it employ technological means to create a “bird-free zone” above the contact wire, but it also strikes a technological balance that ensures the safety of the railway’s lifeline while fostering harmony between humans and nature.
