Abstract

The embodiment of the invention provides a wearable acoustic detection and recognition system. The system comprises a conformal microphone array, an environment camera, a conformal ultrasonic sensor array, a main processor and a display control device. The system determines an operation instruction and locates an object in a to-be-detected space according to the echo information of the ultrasonicsignal sent by the ultrasonic sensor array. In addition, the main processor determines a positioning and tracking target according to the sound signal collected by the conformal microphone array and the environment video image collected by the environment camera. Moreover, the system further comprises a portable backpack which is used for containing the main processor and the power supply device and is internally provided with an interface and a connecting wire. Therefore, the microphone array, the ultrasonic sensor array and the camera are arranged on a wearable device; on one hand, the noisetarget in the space can be positioned and tracked, and on the other hand, all parts can be worn on the body of an operator in combination with the portable backpack and the wearable device, so that both hands of the operator are liberated, the operation complexity is simplified, and the operation agility is improved.

Description

technical field [0001] The invention relates to the technical field of acoustic detection, in particular to a wearable acoustic detection and identification system. Background technique [0002] For engineers and scientific researchers engaged in environmental noise control and equipment acoustic fault diagnosis, they can use acoustic testing equipment or systems to visually observe the distribution characteristics and frequency components of noise in time and space in the space they care about. , quickly locate the location of the noise source, and analyze the signal characteristics of the noise source, which will help improve their work quality and work efficiency. At present, acoustic equipment or systems capable of detecting spatial noise mainly include sound level meters, sound intensity meters, microphone arrays, mobile phone applications, and acoustic cameras. Among them, the sound level meter has defects such as not being able to provide users with information about...
