Problems solved by technology

However, the implementation effect is still not good. The birds either build up their adaptability, or they are frightened and fly around, making it difficult to drive them away
This method of bird repelling strategy is not perfect, and it is not deeply integrated with the rules of bird activities

Embodiment 1

[0067] A kind of method that prevents long-distance straight-flying birds from colliding with aircraft, see figure 1 , including the following steps:

[0068] S1: Obtain the bird activities on the take-off and landing routes;

[0069] S2: Obtain aircraft trajectory information of the aircraft;

[0070] S3: Extract long-distance straight-line flight activities from bird activities, and comprehensively evaluate the probability of bird strikes based on aircraft trajectory information and long-distance straight-line flight activities;

[0071] S4: When the bird strike probability is higher than the preset risk threshold, the bird repelling strategy is carried out according to the preset bird repelling strategy.

[0072] In this embodiment, the method for monitoring bird activities includes monitoring bird flight tracks, quantity, body size and tracking captured images. The method can also record the monitored bird activity data and the aircraft track information broadcast by th...

Embodiment 2

[0143] A system for preventing collisions of birds flying in a straight line over long distances, see Figure 5 ,include:

[0144] Bird activity detection module 1: used to obtain bird activity on the take-off and landing routes;

[0145] Operation and control center 2: connected to the bird activity detection module 1; the operation and control center 2 is used to obtain the aircraft trajectory information of the aircraft; extract the long-distance straight-line flight activities from the bird activities, according to the aircraft trajectory information and long-distance straight-line flight activities The data comprehensively evaluates the probability of bird strikes; when the probability of bird strikes is higher than the preset risk threshold, the bird repellent equipment is activated to repel birds;

[0146] Bird repelling device 3: connected to the operation and control center 2; the bird repelling device 3 is used to repel birds according to the preset bird repelling s...

Abstract

The invention provides a method and a system for preventing long-distance linear flying birds from colliding with an aircraft. The method comprises the following steps: acquiring bird activities on a take-off and landing route; acquiring aircraft trajectory information of the aircraft; extracting a long-distance linear flight activity from the bird activities, and comprehensively evaluating the bird strike probability according to the aircraft trajectory information and the data of the long-distance linear flight activity; and when the bird strike probability is higher than a preset risk threshold value, performing bird repelling according to a preset bird repelling strategy. According to the method, only long-distance linear flying birds are repelled, so that the pertinence of risk prevention is improved, and the problem of bird building adaptability caused by excessive use of bird repelling means is avoided. In addition, bird repelling means are accurately implemented in combination with bird activity rules, the problem that bird repelling means are ineffective or birds frighten and fly disorderly is solved, and the probability of bird strike can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of bird strike prevention at airports, and in particular relates to a method and system for preventing long-distance straight-flying birds from colliding with aircraft. Background technique [0002] Bird strikes occur when birds move close to high-speed aircraft. Bird strike accidents mainly occur during the take-off and landing phase of aircraft, which is the focus of bird strike prevention. When there are bird activities near the take-off and landing routes, they must be driven away in time. Therefore, it is an urgent need for airports to drive birds in time and effectively. [0003] The bird activity with the highest risk of bird strike accidents is long-distance straight-line flight. Typically, a large number of migratory birds fly at night during the migration season (the primary source of bird strike risk). In addition, birds such as herons can also be seen flying back and forth between feeding grou...
