Problems solved by technology

[0003] At present, bird strike prevention mainly uses visual observation or telescope to visually observe bird activities and then uses certain methods to drive birds away. The limitations of this method are obvious, especially in the case of complex surrounding buildings and vegetation. Repelling birds is getting more complicated

Embodiment Construction

[0008] The present invention is described in further detail below. see figure 1 , the present invention provides a bird strike risk assessment system design, which is composed of radar, image acquisition equipment, bird target recognition software, bird strike risk assessment model and bird situation database. Radar includes but not limited to maritime radar, weather radar and air traffic command radar, and outputs video signals in real time. The image acquisition device consists of an image acquisition card or an external image acquisition box, which converts the video signal into a digital radar image, and the digital radar image includes but is not limited to a planar position indication (PPI) image. Flying bird target recognition software recognizes flying bird targets based on digital radar images output by image acquisition equipment and extracts relevant bird situation information. Bird situation information includes but not limited to bird number, bird size, flight he...

Abstract

The invention relates to a design scheme of a bird strike risk assessment system which is composed of a radar, an image acquisition device, a flying bird target recognition software, a bird strike risk assessment model and a bird condition database. The advantages of the invention lies in providing a new strike risk assessment method and the bird condition database established by the bird strike risk assessment method provides favorable technical support for the bird strike prevention work.

Description

technical field [0001] The invention relates to a design scheme of a bird strike risk assessment system, which is mainly applied to bird situation data statistics in bird strike prevention. Background technique [0002] Bird strikes refer to incidents in which an aircraft collides with flying objects such as birds and bats during take-off and landing or flight. Bird strikes have occurred since the advent of aircraft. According to statistics, the annual military and civil aviation losses caused by bird strikes in North America alone exceed 500 million U.S. dollars and endanger the lives of passengers. There are an average of 5.7 bird strikes per 10,000 aircraft takeoffs and landings in Europe. hit. From 2001 to 2007, Civil Aviation of China reported 1,055 bird strikes, resulting in 215 accidents and 217 moderate-level injuries. The direct losses in maintenance statistics exceeded 270 million yuan, and the indirect losses were even more difficult to calculate. Observing and ...
