Abstract

The intelligent reminding system of SCM Based automatic identification noise relates to a kind of detection sound size automatically, and reminds the intelligent reminding system kept quite, and keeps quite especially for reminding people in public place.The present invention provides a kind of simple in construction, and with low cost, the suitability is strong, can be according to the time of different occasion setting work and the system of noise measuring threshold size.Mainly it is made up of sound detection module, single-chip microcomputer, clock timer, speaker, wireless remote control module.Sound detection module can set different sound threshold value sizes according to different place, with judge how many decibels sound as noise；Clock timer may be set in certain time short interior speaker operation, and device can remotely be controlled by wireless remote control module.

Description

The intelligent reminding system of SCM Based automatic identification noise

Technical field

This patent relates to a kind of detection sound size automatically, and reminds the intelligent reminding system kept quite, and particularly uses People are reminded to keep quite in public place.

Background technology

Along with a large amount of rises of mobile phone, call noise has been a problem demanding prompt solution.In hospital, school is often Hear that the sound made a phone call is very big, to such an extent as to have impact on rest and the student learning of patient；Also have some bad noises, as In the time of having a rest, outdoor can not fall asleep too loudly, but answers the call, and makes a phone call or the people talked may not have a mind to Know and bothered others to his behavior.The device now having a size that can automatically detect this kind of sound judges No have influence on other people, and send warning to allow it keep quite.

The most also there is no a intelligent reminding system that can be used for hospital, school or other public places.

Summary of the invention

For some public place human-made noise pollution problems, this patent proposes a kind of simple in construction, it is easy to accomplish Automatically the intelligent reminding system of noise is identified.

Realize the intelligent reminding system automatically identifying noise of technique scheme, by sound detection module, single-chip microcomputer, time Clock intervalometer, speaker, wireless remote control module form.Sound detection module can set different sound according to different places Threshold size, with judge how many decibels sound as noise；Clock timer may be set in certain time short interior speaker work Making, device can remotely be controlled by wireless remote control module.

The advantage of this patent: the intelligent reminding system of SCM Based automatic identification noise, simple in construction, low cost Honest and clean, the suitability is strong, can be according to the time of different occasion setting device work and noise measuring threshold size.

Accompanying drawing explanation

With embodiment, this patent is further illustrated below in conjunction with the accompanying drawings.

The intelligent reminding system construction drawing of the SCM Based automatic identification noise of Fig. 1；

Fig. 2 specific works flow process figure

Detailed description of the invention

As it is shown in figure 1, the intelligent reminding system of SCM Based automatic identification noise is by by sound detection module, monolithic Machine, clock timer, speaker, wireless remote control module form.Operator open single-chip microcomputer by wireless remote control module, at that time When clock intervalometer is to single-chip microcomputer signal, Single-chip Controlling sound detection module works, and sound detection module is by detection and judges It is whether to indicate whether speaker works after noise.

Specific works flow process as in figure 2 it is shown, system open after, clock timer set time range in, single-chip microcomputer Receiving clock signal, Single-chip Controlling sound detection module works；When the decibel of the sound of detection is more than the threshold value set, Speaker operation also reminds other people to keep quite, and after reminding three times, sound detection module again detects surrounding sound and carries out Judging, when sound decibel is less than threshold value, speaker quits work, and when sound decibel is more than threshold value, speaker works on. Time not in the time range that clock timer sets, system does not works.

Claims

The intelligent reminding system of the most SCM Based automatic identification noise, by sound detection module, single-chip microcomputer, clock timing Device, speaker, wireless remote control module form, and it is characterized in that: the switch of wireless remote control module control single chip computer, work as clock timer During to single-chip microcomputer signal, Single-chip Controlling sound detection module works, and sound detection module is by detection and determines whether to make an uproar Indicate whether speaker works after sound.
The intelligent reminding system of SCM Based automatic identification noise the most as claimed in claim 1, is characterized in that: sound is examined Survey module and can set different sound threshold value sizes according to different place, with judge how many decibels sound as noise；Time Clock intervalometer may be set in certain time short interior speaker operation.
