A firefighter breathing sound monitoring earphone and its physical state assessment method

Abstract

A firefighter breathing sound monitoring earphone, including a sound acquisition module, a bone conduction sound playback module, a memory module, a button module, a narrowband IoT module, an STM32 processor module, a power management module and a lithium battery module, and provides a firefighter Physical state assessment methods. When in a fire rescue scene, firefighters wear breathing sound monitoring earphones, which can collect the breathing sound of firefighters at the fire rescue scene at the first time, analyze and identify the physical state of firefighters, and evaluate whether the firefighters in danger. The present invention effectively solves the problem of evaluating the physical state of firefighters in the fire rescue scene, and has the characteristics of flexible expansion, convenient portability, wireless interconnection, and low price, thereby improving the correct recognition rate of different firefighters' physical states and reducing the physical state of firefighters The false acceptance rate of identification reduces the casualty rate of firefighters.

Description

technical field [0001] The invention relates to the field of firefighting, in particular to the technical field of sound processing, in particular to a firefighter breathing sound monitoring earphone and a method for evaluating the body state thereof. Background technique [0002] After the fire broke out, a lot of thick smoke, poisonous gas and fire appeared on the scene. The uncontrollable thick smoke, poisonous gas and fire, personnel injuries and panic caused the rescue scene to be chaotic, and firefighters were prone to accidents and even threatened their lives. Condition. Therefore need a kind of firefighter's physical state evaluation method, the firefighter's physical state is evaluated at the fire rescue scene, in time discover the firefighter that the body appears abnormal condition, carry out the rescue to him in time, save the life of this firefighter. [0003] Because the sound signal can be generated directly and conveniently, and its size reflects the intensi...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the deficiency that the existing technology cannot identify and evaluate the physical state of firefighters in the fire rescue scene, the present invention provides a firefighter breathing sound monitoring earphone and its physical state assessment method, including providing a flexible and moderately priced , easy to carry, easy to expand the breath sound monitoring earphones of firefighters, and provide a method for evaluating the physical state of firefighters with a high recognition rate
