Health real-time monitoring device with sound cavity microphone array and monitoring method thereof

Abstract

The invention relates to a health real-time monitoring device with a sound cavity array and a monitoring method thereof. The health real-time monitoring device comprises an array type sound cavity microphone assembly, a control device and a fixing device, wherein the array type sound cavity microphone assembly comprises at least two sound cavity microphones, which are used for collecting sound emitted in a person to be tested; the control device is used for calculating the sound source position according to the signals collected by the array type sound cavity microphone assembly and carrying out post-processing on the signals collected by the array type sound cavity microphone assembly based on the sound source position to obtain real-time monitoring acoustic signals. A sound-receiving cavity is arranged in each sound cavity microphone of the array type sound cavity microphone assembly, the sound-receiving cavity is provided with an open and sealed opening, so that the tightness of thesound cavity is ensured, and the formed sound cavity microphone is used for enhancing the amplitude of received sound. Each microphone of the microphone assembly is provided with a sound cavity structure, so that the interference of noise signals can be effectively eliminated, and the accuracy of monitoring signals is improved.

Description

technical field [0001] The invention relates to a health real-time monitoring device and method with a sound cavity microphone array, belonging to the field of intelligent wearable equipment and medical equipment. Background technique [0002] At present, personal real-time health care monitoring has gradually played an important role in people's lives. [0003] Personal real-time health care monitoring is a new type of medical care model. Its appearance enables the existing hospital functions to be extended to the family. It not only provides a convenient and comfortable living environment, but also undertakes health education, chronic disease detection, fetal health monitoring, Responsibilities such as elderly life care and health care have very broad market potential. [0004] At present, the existing monitoring devices based on the detection of sound phenomena include fetal heart rate monitoring, cardiopulmonary sound monitoring, etc. During the monitoring process, the ...

AI Technical Summary

Problems solved by technology

[0004] At present, the existing monitoring devices based on the detection of sound phenomena include fetal heart rate monitoring, cardiopulmonary sound monitoring, etc. During the monitoring process, the equipment is always in close contact with the human body, and external noise, human activities, or friction with clothing will generate a lot of noise, while the human body’s All kinds of sound signals are relatively weak and their positions are uncertain. The existing sensor structure is to directly use the sensor to collect sound signals, which cannot effectively eliminate these noises, resulting in inaccurate monitoring results and increasing the difficulty of real-time monitoring.

[0005] The existing medical stethoscope has a sound chamber structure, but when using this structure, a doctor with professional knowledge needs to manually find the sound source position, and the sound signal cannot be automatically collected according to the sound source position, and the stethoscope cannot monitor the human body in real time
