Abstract
The invention discloses an alarming method and an alarming system according to sound sources. In the invention, by pre-recording a first sound source, the acoustic parameters of the first sound source under the condition of needing alarming are determined; by pre-recording a second sound source in real time, the acoustic parameters of the second sound source are determined; and the acoustic parameters of the first sound source and the acoustic parameters of the second sound source are compared respectively. When two or more acoustic parameters of the second sound source exceed alarming threshold values of the acoustic parameters and the duration time of the second sound source achieves a duration time alarming threshold value of the second sound source, an alarm is sent out. The method and the system can discover the abnormal condition of a user in the first place and timely make solutions, thus preventing the family of the user from suffering from irreparable damage; and the method and the system solve the technical problems that due to no noise when the user safety is ensured by video monitoring, in order to know the safety condition of the user, security personnel needs to keep a close watch on a displayer indispensably, so that when the security personnel discovers that the user has an accident or losses things, a period of time passes already and an optimal rescue opportunity is missed.
Description
Technical field
The present invention relates to the acoustic technique field, relate in particular to a kind of method and system of reporting to the police according to sound source.
Background technology
It is very many to lose children now, and careless slightly children just lose, and one family will be wrecked, and goes bankrupt or broke, and more heads of a family are therefore insane; In recent years, a lot of pernicious incidents of violence take place in school, cause a lot of heads of a family when selecting kindergarten or school, all can ask school whether watch-dogs such as " electronic eyes ", " global eyes " are arranged, the head of a family wishes can to monitor in real time by internet, mobile Internet child's situation, but this video monitoring does not have sound, must keep a close watch on display in real time and just can know whether safety of child, when finding that child accident occurs or loses, be after a period of time, missed best rescue opportunity.
Summary of the invention

Every interval 20 seconds to 180 seconds compares the parameters,acoustic of current described second sound source of sound and the parameters,acoustic of described first sound source once;
If the parameters,acoustic of second sound source of sound has two or more to surpass the alarming threshold value of parameters,acoustic, at this moment the opening entry second sound source of sound duration, the parameters,acoustic of described second sound source of sound duration from second sound source of sound has two or more alarming threshold values that surpass parameters,acoustic to begin to calculate;
Whether the parameters,acoustic that at this moment still calculates second sound source of sound has two or more alarming threshold values that surpass parameters,acoustic and second sound source of sound duration to reach second sound source of sound duration alarming threshold value, if then report to the police; If not, then the second sound source of sound duration makes zero;
Described warning can be situations such as phone, note, consumer positioning position;
The further optimization of such scheme is, described step " prerecord first sound source; the acoustic feature of analyzing described first sound source is determined the parameters,acoustic of described first sound source, and described parameters,acoustic comprises: waveform, fundamental frequency, loudness of a sound, the duration of a sound and the rate of articulation; Set the alarming threshold value and the second sound source of sound duration alarming threshold value of each parameters,acoustic, and the alarming threshold value of first sound source, the pairing parameters,acoustic of first sound source and each parameters,acoustic stored as the first sound source information " can also " prerecord first sound source for step, the acoustic feature of analyzing described first sound source is determined the parameters,acoustic of described first sound source, and described parameters,acoustic comprises: waveform, fundamental frequency, loudness of a sound, the duration of a sound and the rate of articulation; Set the alarming threshold value and the 3rd sound source duration alarming threshold value of each parameters,acoustic, and the alarming threshold value of first sound source, the pairing parameters,acoustic of first sound source and each parameters,acoustic is stored as the first sound source information ";
Described step " is recorded second sound source of sound; search the pairing first sound source information of second sound source of sound; the acoustic feature of analyzing second sound source of sound is determined the parameters,acoustic of described second sound source of sound " can also " record second sound source of sound; search the pairing first sound source information of second sound source of sound; determine the 3rd sound source according to the parameters,acoustic of described first sound source, the acoustic feature of analyzing the 3rd sound source is determined the parameters,acoustic of described the 3rd sound source " for step;
When described second sound source of sound comprises third-party sound, at this moment just need filter second sound source of sound, extract the pairing third party's sound source of active user;
" parameters,acoustic of the parameters,acoustic of described second sound source of sound and described first sound source compares respectively; if the parameters,acoustic of second sound source of sound has two or more to reach the alarming threshold value of parameters,acoustic; then begin the accumulative total second sound source of sound duration; when the parameters,acoustic of second sound source of sound has two or more alarming threshold values that reach parameters,acoustic and second sound source of sound duration to reach second sound source of sound duration alarming threshold value; then report to the police " can also " parameters,acoustic of the parameters,acoustic of described the 3rd sound source and described first sound source compares respectively described step; if the parameters,acoustic of the 3rd sound source has two or more to reach the alarming threshold value of parameters,acoustic for step, then begin the 3rd sound source duration of accumulative total, when the parameters,acoustic of the 3rd sound source has two or more alarming threshold values that reach parameters,acoustic and the 3rd sound source duration to reach the 3rd sound source duration alarming threshold value, then report to the police ".
In the embodiment of the invention by prerecording first sound source, the parameters,acoustic of first sound source under the situation of determining to need to report to the police, by real-time recording second sound source of sound, determine the parameters,acoustic of described second sound source of sound, the parameters,acoustic of the parameters,acoustic of described second sound source of sound and described first sound source compares respectively, when the parameters,acoustic of second sound source of sound has two or more alarming threshold values that surpass parameters,acoustic and second sound source of sound duration to reach second sound source of sound duration alarming threshold value, then report to the police, guarantee that abnormal conditions appear in very first time discovery user, in time make counter-measure, avoid subscriber household to suffer the infringement that can't remedy, solved and do not had sound when guaranteeing user security by video monitoring, must keep a close watch on display in real time and just can know whether safety of user, when finding that the user accident occurs or loses, be after a period of time, missed the best rescue technical matters on opportunity; Especially, when comprising third-party sound in the second sound source of sound, go out three sound source corresponding by filter analysis with the user, compare respectively by the parameters,acoustic of described the 3rd sound source and the parameters,acoustic of described first sound source, when the parameters,acoustic of the 3rd sound source has two or more alarming threshold values that reach parameters,acoustic and the 3rd sound source duration to reach the 3rd sound source duration alarming threshold value, then report to the police, further guarantee user's safety.
