Bird striking risk assessment system and assessment method thereof

Abstract

The invention discloses a bird striking risk assessment system and an assessment method thereof. The system comprises a radar, an image acquisition device, a flyer target recognition module, a bird striking risk assessment model and an avian situation database, wherein the radar can output video signals in real time, the image acquisition device can convert the video signals into digital radar images, the flyer target recognition module is used for recognizing flyer targets and extracting relevant avian situation information based on the digital radar images outputted by the image acquisitiondevice, the bird striking risk assessment model can assess real-time bird striking risks on the basis of the avian situation information extracted by the flyer target recognition module and output bird striking risk factors, and the avian situation database is used for storing the avian situation information extracted by the flyer target recognition module and the bird striking risk factors givenby the bird striking risk assessment model. The method is capable of early warning and mastering flyer situation around an airport accurately, and is convenient for workers to clean and convenient for airplane pilots to avoid risks effectively.

Description

technical field [0001] The invention belongs to the technical field of risk assessment, and relates to a bird strike risk assessment technology, which is mainly applied to the statistics of bird situation data in bird strike prevention, and specifically refers to a bird strike risk assessment based on bird situation information extracted from radar images. The system of evaluation and its evaluation method. 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 b...

AI Technical Summary

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
