本申请涉及一种飞机噪声的自动监测方法,通过在机场设置能够自动监测环境噪声的噪声监测设备,每隔预设时间获取一次机场的环境噪声信号并转换为数字信号序列,并通过提取数字信号序列的噪声特征信息自动查找飞行噪声事件,最后通过据每一架进入机场的飞机的飞机当前坐标,以及机场中每一条机场跑道的起点坐标和终点坐标,计算出进入机场的飞机具体是进入哪条机场跑道、飞机在机场跑道中的方位,为飞行噪声事件的判断提供了充足的证据,实现机场周围飞机噪声的自动监测和飞机状态的实时全面的分析。
The invention relates to an automatic monitoring method for aircraft noise, which comprises the following steps of: arranging noise monitoring equipment capable of automatically monitoring environmental noise at an airport, acquiring an environmental noise signal of the airport every preset time, converting the environmental noise signal into a digital signal sequence, and automatically searching a flight noise event by extracting noise characteristic information of the digital signal sequence. And finally, according to the current coordinates of each airplane entering the airport and the starting point coordinates and the end point coordinates of each airport runway in the airport, the airport runway which the airplane entering the airport specifically enters and the orientation of the airplane in the airport runway are calculated, sufficient evidence is provided for judgment of a flight noise event, and the accuracy of the flight noise event is improved. Automatic monitoring of aircraft noise around an airport and real-time comprehensive analysis of aircraft states are realized.
