Embodiment
With reference to the accompanying drawings and examples, the embodiment of the present invention is described in further detail.Implement below
Example is used to illustrate the present invention, but is not limited to the scope of the present invention.
As shown in Figure 1, a kind of noise alarm system of the present invention, it is characterised in that adopted including noise transducer 1, data
Collection module 2, central processing unit 3 and alarm 4, noise transducer 1 are connected with the input terminal of data acquisition module 2, data acquisition
The output terminal of module 2 is connected with the input terminal of central processing unit 3, and the output terminal of central processing unit 3 is connected with alarm module.
Based on above-mentioned technical proposal, noise transducer 1 is used to collect the voice signal played from speaker, data acquisition module
The input terminal of block 2 is connected with noise transducer 1, for collecting the letter voice signal from noise transducer 1, central processing unit 3
Input terminal be connected with the output terminal of data acquisition module 2, it is and right for handling the voice signal from data acquisition module 2
Voice signal from data acquisition module 2 is analyzed and classified, and the course of work of noise alarm system is noise transducer 1
The voice signal played from speaker is collected, data acquisition module 2 is acquired the signal from noise transducer 1, and
Numerical operation and transmission are carried out to the signal from noise transducer 1, centre is transferred to by the signal of data acquisition module 2
Device 3 is managed, central processing unit 3 analyzes and processes the signal from data acquisition module 2, and analyzing the voice signal collected is
No to exceed set preset value, as voice signal exceedes set preset value, then alarm 4 works.
In the present embodiment, as shown in Figure 1, central processing unit 3 includes audio decoder 31, data processing module 32 and noise
Judgment module 33, the input terminal of audio decoder 31 are connected with the output terminal of data acquisition module 2, the output of audio decoder 31
End is connected with the input terminal of data processing module 32, the output terminal of data processing module 32 and the input terminal of noise judgment module 33
Connection, the output terminal of noise judgment module 33 and the input terminal of alarm module connect；By arrangement above, can obtain, audio decoder
31 receive the signal from data acquisition module 2, and it are decoded, decoded signal incoming data processing module 32
In, data processing module 32 handles decoded signal, and being sent to noise by the signal of data processing module 32 sentences
In disconnected module 33, noise judgment module 33 judges the signal from data processing module 32, differentiate the signal size whether
More than the preset value of setting, if the size of the signal exceedes the preset value of setting, noise judgment module 33 sends signal to report
In alert device 4, alarm 4 can then work, and remind user suitably to reduce the sound size that speaker is played.
In the present embodiment, noise transducer 1 is set to two, is respectively arranged in the both sides of speaker, avoids noise transducer 1 from pacifying
Mounted in the side of speaker so as to produce noise sensing deviation, the inaccuracy of 1 signal collection of noise transducer is caused.
In the present embodiment, alarm 4 is located at the top of speaker, can be preferably by the way that alarm 4 to be located to the top of speaker
The sound of alarm 4 is propagated, improves its warning effect.
In the present embodiment, as shown in Figure 1, data acquisition module 2 uses NI9215A data collecting cards, NI9215A data are adopted
Truck has the function of integrated form signal condition, and measurement is fast and simple, has stronger practicality.
In the present embodiment, as shown in Figure 1, data processing module 32 is microcontroller, the type of microcontroller is embedded monolithic
Machine, the integrated level of embedded scm is high, small, and reliability is high, to the obvious processing effect of signal.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and replacement can also be made, these improve and replace
Also it should be regarded as protection scope of the present invention.
