Description

Technical Field

[0001] This invention belongs to the field of airport bird monitoring technology, and more specifically, relates to a model-based airport bird identification method and system. Background Technology

[0002] The presence of birds at an airport can have multifaceted impacts on aviation safety, operational efficiency, and the economy.

[0003] Here are some of the main impacts:

[0004] 1. Aviation safety risks

[0005] Bird strikes are a significant safety hazard in aviation, especially during takeoff and landing. A collision between a bird and an aircraft can lead to a serious accident, or even a crash. The main risks of bird strikes include:

[0006] Aircraft structural damage: Bird strikes can damage an aircraft's engines, wings, fuselage, or windshield. Large birds or flocks of birds, in particular, can put significant stress on the aircraft's wings and engines.

[0007] Engine failure: Bird strikes to the engine can cause it to stop, especially during the initial stages of takeoff, resulting in engine damage or an emergency landing.

[0008] Obstruction of vision: Birds may strike the cockpit windshield, affecting the pilot's vision and even breaking the glass, endangering the pilot's safety.

[0009] Damage to aircraft instruments: Bird strikes can damage an aircraft's sensors, radar systems, or other critical instruments, affecting the aircraft's navigation and control systems.

[0010] 2. Flight delays and decreased operational efficiency

[0011] Airports with high bird activity typically require additional measures to reduce the risk of bird strikes, such as:

[0012] Increased patrols and surveillance: Airports will assign dedicated personnel to drive away and monitor birds, increasing workload and costs.

[0013] Flight delays: Bird strikes can cause temporary delays or cancellations, especially during large-scale bird strikes or when airports have to implement emergency landing procedures. Delays not only affect on-time performance but can also damage trust between airlines and passengers.

[0014] Aircraft inspection and maintenance: Bird strikes can damage aircraft, requiring airlines to inspect and maintain them, increasing operating costs and downtime.

[0015] In conclusion, bird identification and deterrence at airports can play a role in ensuring safe operations. However, the accuracy of existing technologies for bird identification is not high, and misjudgments are prone to occur. Summary of the Invention
