[0026] Please refer to figure 2 , figure 2 It is a flowchart of an aircraft noise monitoring method provided by the first embodiment of the present invention. The following will be figure 2 The process shown is described in detail, and the method includes:

[0027] Step S110: Obtain flight parameters and actual meteorological data of the aircraft in the monitoring environment. The flight parameters include aircraft type, engine power, and airport runway information. The actual meteorological data include air pressure, air temperature, relative humidity, and wind speed.

[0028] According to the regulations of ICAO (International Civil Aviation Organization), the meteorological conditions for airport noise measurement are: pressure value 1013.25 hPa, temperature 25 degrees Celsius, relative humidity 70% and no wind. However, the meteorological conditions of the airport are usually difficult to meet this standard. In actual measurement, the temperature value is 2 degrees Cel...

Abstract

The invention provides an aircraft noise monitoring method and device. The method comprises the following steps of acquiring flight parameters and actual meteorological data of an aircraft in the monitoring environment, correcting a flight path of the aircraft at an airfield runway, acquiring a random predicted point, calculating a slant range between the aircraft and the random predicted point, calculating and obtaining effective perceived noise levels of the aircraft based on the maximum takeoff weight and the slant range of the aircraft, based on takeoff and landing aircraft times of each type aircraft obtained in advance at each airfield runway in a first period, calculating average values of the effective perceived noise levels of the aircraft, calculating and obtaining weighted equivalent continuous perceive noise levels based on takeoff and landing aircraft times of the aircraft in each second period and the average values of the effective perceived noise levels, a plurality of second periods are obtained in advance in the first period. By adopting the method, the problems that a traditional aircraft program noise monitoring method is accidental and can not evaluate the noise impact caused by aircraft noise objectively and accurately can be alleviated.

Description

technical field [0001] The invention relates to the field of noise monitoring, in particular to an aircraft noise monitoring method and device thereof. Background technique [0002] With the rapid growth of flight volume and the increase of new airport construction and airport expansion projects, the problem of aviation noise at airports has become increasingly prominent. The evaluation of aircraft should not only consider safety, economy and simplicity, but also pay attention to noise evaluation. Traditional aircraft noise monitoring methods mainly use the noise of a single event as an evaluation index, which is accidental and cannot objectively and accurately evaluate the noise impact of aircraft noise. Contents of the invention [0003] In view of this, the purpose of the embodiments of the present invention is to provide an aircraft noise monitoring method and device thereof. [0004] In the first aspect, an embodiment of the present invention provides a method for m...
