Multifunctional electroacoustic communication device and use method

Abstract

The invention discloses a multifunctional electroacoustic communication device and a use method. Comprising a microcontroller, a key module, a poison gas sensor array, a voice prompt module, a Bluetooth audio module, a pickup, a power amplification module, a miniature loudspeaker, a communication main cavity, a power module, a battery, a battery bin, a sensor assembly cavity, an assembly plate, a charging interface, an expiration cavity, a sound amplification port and a positioning module. While sound amplification is completed, various environmental gases can be monitored and early warned, gas data sharing is formed through Bluetooth networking of multiple electroacoustic devices, multi-point dynamic monitoring of the gas concentration in an operation area is further achieved, the failure time of a filter element is early warned in combination with a timer, and the working efficiency is improved. Real-time monitoring and early warning of the gas mask filter are realized; early warning can be carried out on a next moving route of a user according to regional gas concentration data of a working site; rescue and evacuation routes may be effectively indicated when the filter is about to reach or has exceeded a threshold.

Description

technical field [0001] The invention belongs to the technical field of gas mask communication, and in particular relates to a multifunctional electro-acoustic communication device and a using method. Background technique [0002] Call and gas monitoring and early warning capabilities are an important function of gas masks. At present, existing gas masks have a single electro-acoustic communication function and only have sound reinforcement capabilities. Gas masks have no gas monitoring and early warning capabilities, and face complex toxic and harmful gas environments. , When the concentration of toxic and harmful gases in the working environment is too high, and there is no poison gas monitoring and warning for the operators to enter the working environment, it will increase potential risks to the safety of the operators. Judging by the operator's experience will greatly threaten the safety of the operator's life. Further, in the operation, it is often necessary to connect ...

AI Technical Summary

Problems solved by technology

In addition to completing the sound amplification function, the present invention can also sense the life characteristics of the personnel wearing the gas mask performing dangerous operations in real time, so that the command terminal can control the work of the personnel wearing the gas mask performing dangerous operations in real time; however, the gas mask still cannot effectively determine the filter element Whether it is invalid or not, it is impossible to form the distribution of harmful gas concentration and species in the unknown operation area through the positioning of multiple gas masks and gas monitoring capabilities, so that data guidance for escape and rescue cannot be provided in time
