Abstract

The invention discloses a multifunctional fire-fighting helmet. The helmet comprises a helmet body, a wireless communication system, an electronic compass and an environment display system; the wireless communication system, the electronic compass and the environment display system are all installed on the helmet body in a matched mode; the wireless communication system comprises an antenna, a receiving and transmitting band-pass filter, a high-frequency amplifier, a frequency synthesizer, an MFSL modulator, a voltage-controlled oscillator, an encipherer, an ADC, audio frequency amplifiers, a de-noising device, a bone conduction microphone, a master control IC, a BMS power management system, a polymer battery, a frequency-selective amplifier, a frequency discriminator, a frequency mixer, a local oscillator, an audio frequency decoder, a decipher and a loudspeaker. By means of the multifunctional fire-fighting helmet, both hands of a fireman can be liberated, the golden rescue capability of the fireman is enhanced, the awkward problem that by means of a traditional helmet, it is difficult to wear an air-breathing gas mask is solved, it is achieved that the data communication serves as a part of the entire helmet, and the helmet is convenient for the fireman to wear, simple and convenient to operate and convenient to maintain.

Description

technical field [0001] The invention relates to the field of firefighting equipment, in particular to a multifunctional firefighting helmet. Background technique [0002] At present, fire helmets in the market have only a simple head protection function and do not have other functions. Firefighter communication requires additional communication equipment. The communication equipment that firefighters are often equipped with is an analog walkie-talkie. This machine is bulky, and the upload signal uses a microphone as the sound source, which is easily disturbed. It has many general functions and cumbersome operation, which is not conducive to use in emergency situations. Firefighters cannot completely free their hands, which delays the rescue time, and the rescue efficiency is low. They no longer use the walkie-talkie to shout loudly. [0003] The fire helmet that is now equipped with a microphone is used as a sound source, and a lot of noise is superimposed on the sound sou...
