Embodiment Construction

[0038] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0039] This algorithm is based on the pan-grid airport noise data, and a large number of noise monitoring nodes are arranged in a pan-grid layout in the monitoring area around the airport. However, when the monitoring area is divided according to the grid, the coordinates of the monitoring points will not be strictly in the grid point position. Therefore, the purpose of this algorithm is to interpolate the gridded monitoring area to provide accurate standard grid noise data for the noise monitoring area.

[0040] The specific steps of this algorithm are as follows:

[0041] 1. Grid division of the entire monitoring area. Such as figure 1 , assuming that the distance between monitoring points is assumed to be D when arranging pan-grid monitoring points, and the distance between grid points during grid division is L. Then, when performing grid di...

Abstract

The invention discloses an aircraft noise interpolation method based on generic gridding airport perception. The method comprises the following steps: performing gridding interpolation operation on the monitoring area again, and providing accurate standard gridding noise data for the noise monitoring area. According to the method disclosed by the invention, the generic gridding monitoring point noise data are converted into standard gridding noise data in the airport noise monitoring area by virtue of interpolation operation, so that the converted data are easier to store compared with the original data, persistent operation of the noise data can be realized, and a formative data support is provided for in-depth study of airport noise in future.

Description

technical field [0001] The invention relates to an aviation noise interpolation method based on pan-grid airport perception, and belongs to the technical field of noise monitoring. Background technique [0002] In recent years, despite the rapid development of my country's civil aviation industry, air transport resources are still very tight. In terms of infrastructure, the number and capacity of airports are already seriously inadequate. According to statistics, at the end of 2010, 26 airports among the top 50 airports in terms of throughput were saturated, and it is expected that the other 24 airports will also reach saturation in 2015. In order to solve the problem of shortage of air transportation resources, the number of civil transportation airports nationwide is planned to reach more than 230 by the end of the "Twelfth Five-Year Plan". In 2011, only 5 new airports were actually added, in 2012, 3, and at the beginning of 2013, 14 new airports were expected to be adde...
