Embodiment 1

[0052] A single soldier, including a helmet body, a helmet body, a microphone array module, a AI edge computing module, a AR eyepiece, and a 9-axis sensor; where:

[0053] The microphone array module is used to collect sound signals of the surrounding environment;

[0054] Specifically, the microphone array module includes 9 high-precision MEMS microphones, which are provided on top and side of the helmet body, thereby rowing a universal sound field positioning round surface with low power, miniaturization, high real time and high integration. Array module. When a target having high threats can be collected by a high-precision microphone-shaped array module, the microphone array module picks up the sound signal through the environment medium, and performs A / D conversion and pretreatment of the picked up the sound signal. The purpose of pretreatment is to suppress noise in the original sound signal, improve signal distortion, etc., improve the signal-to-noise ratio of the sound s...

Embodiment 2

[0074] This embodiment also provides a target sound source and sound pattern recognition method for a single soldier helmet, which includes the following steps:

[0075] S1: Collect the sound signal of the surrounding environment;

[0076] S2: Depending on the sound signal of the sound signal and the sound source category of the sound signal; wherein the relative sound source position is the geographic location of the sound signal relative to the individual soldier;

[0077] S3: Get the position data of the helmet body, and obtain the actual sound source position of the sound signal according to the position data and the relative sound source position;

[0078] Among them, the actual sound source position is the geographic location of the sound source of the sound signal relative to the geographical position of the land coordinate system.

[0079] Further, such as figure 2 As shown, the relative sound source position of obtaining the sound signal according to the sound signal incl...

Abstract

The invention discloses an individual soldier helmet and a target sound source positioning and voiceprint recognition method thereof. The individual soldier helmet comprises: a helmet body, wherein the helmet body is provided with a microphone array module, an AI edge calculation module, an AR eyepiece and a 9-axis sensor; a microphone array module which is used for collecting sound signals of the surrounding environment; a 9-axis sensor which is used for acquiring position data of the helmet body; AI edge computing equipment which is used for acquiring a relative sound source position of the sound signal and a sound source type of the sound signal according to the sound signal, and is also used for acquiring the actual sound source position of the sound signal according to the position data and the relative sound source position; and an AR eyepiece which is used for displaying the actual sound source position and the sound source category. The invention aims to provide an individual soldier helmet and a target sound source positioning and voiceprint recognition method thereof. The problems that the real-time performance of a sound source positioning technology is not high, the position prompt of a sound source target is not visual enough, and the accuracy of voiceprint recognition is low are solved.

Description

Technical field [0001] The present invention relates to the field of sound signal recognition, and more particularly to a single soldier helmet and its target sound source positioning and sound pattern recognition. Background technique [0002] With the development of information technology, the modern war morphology and pattern have undergone profound changes, which puts forward new requirements for individuals' ability and development. The role of a single soldier is no longer only a protective head function, but a variety of intelligent integrated technologies are combined, and the auxiliary persons can better implement various tasks. With the application of key technologies such as artificial intelligence technology, AR miniaturization, the application of intelligent single combat information equipment is moving towards integrated, lightweight and intelligent. During the actual implementation of the task, it is necessary to "eye-eye six roads, ear to listen to eight parties",...
