Description
Technical field
The utility model is related to a kind of intercom system, more particularly to a kind of Bluetooth talkback system.
Background technology
It is to be difficult to avoid that in modern society's fire, very big pressure is so brought to fire-fighting work, disappears in fire extinguishing procedure
Communication between anti-member turns into the key of fire fighting, and the situation of audio signal cannot not be heard caused by external interference factor is excessive, with
And when communication apparatus is interfered, have a strong impact on fire fighting progress and difficulty.Intercom is characterized in anti-as conventional communication tool
Interference is strong, applied widely, stablize easy to operate, but due to volume and weight problem, the particularity of fireman's occupation in addition,
Cause hand-held intercom very inconvenient, in some instances it may even be possible to cause danger.So Bluetooth adapter is designed it is contemplated that arriving, by indigo plant
Tooth is connected with intercom, different bluetooth modules is designed, to realize different functions.
The utility model a kind of intercom system for fireman provides, it is contemplated that the working environment complexity and situation of fireman
It is changeable, therefore audio power amplifier circuit is increased, make fireman that volume can be adjusted under different demands, solve external interference
The situation of audio signal cannot not be heard caused by factor is excessive, when many people go deep into the situation in the scene of a fire jointly, is entered with talk back equipment
Row communication obviously some break a butterfly on the wheel swat a fly with a cannon, so also specially devising speaker portion, unclean language in the helmet is passed through
Loudspeaker directly sends, and the people of so surrounding can hear in time, avoids the trouble of intercommunication transmission, and easily by disaster victims and people trapped in danger
Hear, beneficial to the carrying out of fireman rescue work.
Utility model content
The purpose of this utility model is in order to solve the above-mentioned technical problem, and then to provide a kind of Bluetooth talkback system, its knot
Structure is simple, and easy to operate, one after another is high, high safety.
The technical solution of the utility model：
A kind of Bluetooth talkback system, including：Intercom, Bluetooth adapter, main frame bluetooth module, slave bluetooth module, cut
Key-press module, speech recognition, microphone, squelch circuit, power amplifier module, loudspeaker and earphone are changed,
The intercom is connected by Bluetooth adapter with main frame bluetooth module；
The microphone connects and is connected with speech recognition；
The speech recognition is connected with switching key module；
The switching key module is connected with slave bluetooth module and squelch circuit respectively；
The squelch circuit is connected with power amplifier module；
The power amplifier module is connected with loudspeaker and earphone respectively；
The slave bluetooth module is mutually communicated with main frame bluetooth module.
To further restriction of the present utility model, the speech recognition model LD3320.
To further restriction of the present utility model, the model LB002 of the Bluetooth adapter.
To further restriction of the present utility model, the model Motorola GP328 of the intercom.
The utility model has the advantages that：
1st, the utility model increased audio power amplifier circuit, make fireman that volume can be adjusted under different demands, solution
The situation of audio signal cannot not be heard caused by external interference of having determined factor is excessive.
2nd, the utility model is by the way of button switches and two kinds of switch modes of speech recognition are combined, it is contemplated that different works
Make under environment, the difference of fireman's ability to act, and such as there is chance failure in a kind of mode, another way can alternatively make
Design.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the circuit diagram of the utility model main frame bluetooth module and slave bluetooth module；
Fig. 3 is the utility model power amplifier module circuit diagram；
Fig. 4 is the structural representation of the utility model switching key module；
Fig. 5 is squelch circuit figure of the present utility model.
Specific embodiment
The utility model is described in detail below with reference to accompanying drawing.
A kind of Bluetooth talkback system, including：Intercom, Bluetooth adapter, main frame bluetooth module, slave bluetooth module, cut
Key-press module, speech recognition, microphone, squelch circuit, power amplifier module, loudspeaker and earphone are changed,
The intercom is connected by Bluetooth adapter with main frame bluetooth module；
The microphone connects and is connected with speech recognition；
The speech recognition is connected with switching key module；
The switching key module is connected with slave bluetooth module and squelch circuit respectively；
The squelch circuit is connected with power amplifier module；
The power amplifier module is connected with loudspeaker and earphone respectively；
The slave bluetooth module is mutually communicated with main frame bluetooth module.
The speech recognition model LD3320.
The model LB002 of the Bluetooth adapter.
The model Motorola GP328 of the intercom.
Voice command is carried out to system, because scene of fire situation is complicated, two kinds of hairs of transmission Audio Design of intercom system
Send mode, i.e. Voice command and manual PTT button sending method.
The utility model increased audio power amplifier circuit, make fireman that volume can be adjusted under different demands, solve
The situation of audio signal cannot not be heard caused by external interference factor is excessive.
The utility model is by the way of button switches and two kinds of switch modes of speech recognition are combined, it is contemplated that different operating
Under environment, such as there is chance failure in a kind of difference of fireman's ability to act, and mode, and another way can be used alternatively
Design.
Intercom converts tones into electric signal and is sent to slave bluetooth module, slave bluetooth mould by main frame bluetooth module
Block removes noise by squelch circuit, and sound is sent in earphone by power amplifier module then.
Microphone is converted tones into electric signal and is processed by speech recognition, a kind of then by switching key module
Electric signal is sent to main frame bluetooth module by mode by slave bluetooth module, and another kind is by squelch circuit and power amplification electricity
Road, is finally converted into sound by loudspeaker.
