Sound control communication positive pressure type fire-fighting air respirator and using method thereof

Abstract

The invention discloses a sound control communication positive pressure type fire-fighting air respirator and a using method thereof. The sound control communication positive pressure type fire-fighting air respirator comprises a supporting assembly, a breathing assembly and a communication assembly, wherein the supporting assembly comprises a back plate, shoulder straps and a waist strap; the breathing assembly comprises a mask and an air bottle, and the mask is fixedly communicated with the air bottle through an air pipe; and the communication assembly comprises a communication controller and an interphone, the communication controller is electrically connected with the interphone through a connecting line. The using method of the sound control communication positive pressure type fire-fighting air respirator comprises the steps of wearing the device, starting the breathing assembly and starting the communication assembly. According to the sound control communication positive pressure type fire-fighting air respirator, the communication controller adopts the sound control PTT technology, normal conversation can be realized without manual operation, and thus the two hands of a user are liberated; and the interference of noise is eliminated by adopting the DSP digital operation processing technology and the CMOS technology, so that a worker can carry out conversation communication with a field partner and a background commander like normal talking.

Description

technical field [0001] The invention relates to the technical field of fire-fighting air respirators, in particular to a voice-activated communication positive-pressure fire-fighting air respirator and a method for using the same. Background technique [0002] The fire-fighting air respirator is a self-contained open air respirator, which is widely used in fire protection, chemical industry, shipbuilding, petroleum, smelting, warehouses, laboratories and mines. Firefighting, emergency rescue and rescue work can be carried out safely and effectively in various environments such as hypoxia and hypoxia. With the advancement of technology, fire-fighting air respirators have also begun to be equipped with communication functions. [0003] At present, when using positive-pressure fire-fighting air breathing apparatus with communication function, because the staff wear heavy heavy-duty chemical protective clothing or fire-proof clothing, communication will become somewhat difficult...
