Airport environment noise automatic detection system and monitoring method

Abstract

The invention discloses an airport environment noise automatic detection system and a monitoring method. An acoustic sensor and vector judgment module, a noise feature extraction and judgment module,a monitoring and recording module, a meteorological acquisition unit and the like are connected in parallel, and then are connected to a main control computer through a bus to form a noise detection system. M x N acoustic sensors with uniform grid array distribution points and a vector judgment module are arranged on the two sides of the airport runway, and the take-off or landing state of the airplane is judged according to the feedback sound field signal change. Noise intensity distribution in a detection time period is obtained through noise feature extraction and discrimination, noise source attenuation features, directions, elapsed time and airplane type features in a monitoring area are obtained and recorded at the same time, and the airplane type and the flight state are quantitatively judged through a radar signal collector in a monitoring and recording module. A detection result is calculated and analyzed by the main control computer, and airport environment noise data information is sent in real time. The adopted technical method can be transplanted along a high-speed rail to implement noise monitoring on a specific area.

Description

technical field [0001] The invention belongs to the field of environmental protection noise monitoring, and mainly relates to an automatic discrimination and monitoring technology of airport environmental noise. Background technique [0002] With the increasing requirements for people's quality of life and physical and mental health, while air transportation and high-speed railways are developing rapidly, the noise brought by these means of transportation has also become an invisible killer, which affects the mental state of people's work and life. Caused different degrees of impact, so the international noise has been listed as one of the public hazards of environmental pollution. Especially in recent years, the reconstruction and expansion of the airport have further increased the number of airstrips, aggravating the pollution of the noise environment and the corresponding governance problems. Due to the increasingly prominent problem of noise impact, the number of group ...
