The invention provides a navigation emergency alarm device and method for sound source direction finding, and relates to the technical field of navigation alarm, and the method comprises the steps: a hazard source direction finding precision configuration module is used for configuring hazard source direction finding precision; the direction change degree calculation module is used for calculating to obtain a direction change degree; the danger source distance analysis module is used for obtaining a danger source distance; and the navigation emergency alarm judgment module is used for obtaining a navigation emergency alarm result. According to the invention, the technical problem that the navigation safety is influenced because the dangerous source cannot be accurately positioned and the direction and distance cannot be judged in real time due to the interference of environmental noise and the dynamic change of the direction of the dangerous source in the navigation process can be solved, and the aim of improving the navigation safety through the dynamic direction finding and distance analysis of the audio information array is achieved. The method has the technical effects of quickly identifying the direction change and distance of the hazard source, carrying out emergency alarm judgment according to the hazard level classification precision, improving the hazard source detection precision and the alarm response speed, and ensuring the navigation safety.

    本申请提供了一种音源测向的航行紧急报警装置及方法,涉及航行报警技术领域,该方法包括:危险源测向精度配置模块用于配置危险源测向精度;方向变化度计算模块用于计算获得方向变化度;危险源距离分析模块用于获得危险源距离;航行紧急报警判别模块用于获得航行紧急报警结果。通过本申请可以解决在航行过程中由于环境噪声干扰和危险源方向动态变化,导致危险源无法精准定位及其方向和距离无法实时判断,从而影响航行安全的技术问题,达到通过音频信息阵列的动态测向和距离分析,快速识别危险源方向变化和距离,并依据危险等级分类精度进行紧急报警判别,提高危险源检测精度和报警响应速度,保障航行安全的技术效果。
