It is vibrated according to the unlatching of motor starting signal, user to be prompted to have baby crying or there is a ring at the door instantly.
According to above-described embodiment, the invention discloses a kind of control methods of sound detection system for prompting：Include following mistake
Journey：As shown in fig. 7, setting whether open sound detection system for prompting function with display module 60 by interaction, selection is to enter
It chooses whether to open baby's crying detector, if selection is system initialization, system for prompting function is detected into baby's crying.
Above system starts to be detected ambient sound, around voice messaging collecting unit 2000 in real time acquisition
Voice messaging in environment；Collected voice messaging is first split into speech frame by speech signal analysis unit 2001, and frame length is
150 milliseconds, it is 50 milliseconds that frame, which moves, then makees plus Hanning window is handled, finally carry out Fast Fourier Transform (FFT) to every frame voice, will
Treated transmission of speech information is to voice messaging identifying unit 2002；Above-mentioned voice identifying unit 2002 calculates 1kHz and arrives
Ratio between 3kHz frequency bands energy and a frame energy summation, it is comprehensive by speech frame of the ratio more than 0.4 labeled as crying frame
Continuous 20 frame is closed, when it is crying frame there are more than 10 frames in continuous 20 frame, judgement detects vagitus, and baby cry is believed
Breath is sent to main control module 10.
After main control module 10 receives the baby cry information that 200 module of vagitus identification module sends over, by baby
Information of crying and screaming is sent to audio-frequency module 50；Or it is sent to communication module simultaneously, master control module controls audio-frequency module 50 and sounding
Module 90 plays the tinkle of bells；Or motor open signal is sent simultaneously, motor is made to open vibration.Communication module receives main control module
After the information that 10 babies sent are crying and screaming, alarm short message is sent to preset phone number.
Set whether open sound detection system for prompting function with display module 60 by interaction, selection is, into selection
Whether doorbell sound detector is opened, if selection is system initialization, into doorbell sound detection system for prompting function.
As shown in figure 8, above system starts to be detected ambient sound, adopted in real time by doorbell sound detection unit 2010
Collect the acoustic information in ambient enviroment, 2010 collected acoustic information of doorbell sound detection unit is passed sequentially through into filter unit
2011 are handled into line noise filter, and processing is amplified by amplifying unit 2012, will be above-mentioned by AD conversion unit 2013
Amplified acoustic information is converted into digital sound information；It is called by doorbell sound judging unit 2014 pre- in memory module 70
Itself and above-mentioned audio file are carried out comparison judgement by the doorbell sound frequency file deposited, if the digital sound information and above-mentioned audio text
The acoustic information of part is consistent, then is judged as detecting doorbell sound, and will determine that result is sent to above-mentioned main control module 10, if differing
It causes, then continues to acquire the acoustic information in environment.
Main control module 10 receives doorbell that above-mentioned doorbell sound judging unit 2014 transmits just after jingle bell information, by door
Bell is just sent to audio-frequency module 50 in jingle bell information；Or it is sent to communication module 40 simultaneously, master control module controls audio-frequency module
50 play the tinkle of bells with sounding module 90；Or motor open signal is sent simultaneously, motor is made to open vibration.Communication module 40 receives
The doorbell sent to main control module 10 sends alarm short message just after jingle bell information, to preset phone number.
