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
Lose now children very many, slightly careless 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 occur in school, cause a lot of heads of a family all can ask school when selecting kindergarten or school whether the watch-dogs such as " electronic eyes ", " global eyes " are arranged, the head of a family wishes and can arrive child's situation by Real Time Monitoring by internet, mobile Internet, but this video monitoring does not have sound, must keep a close watch in real time display and just can know whether safety of child, when finding that accident or loss appear in child, be after a period of time, missed best rescue opportunity.
Summary of the invention
The purpose of the embodiment of the present invention is to propose a kind of method of reporting to the police according to sound source, be intended to solve and there is no sound when guaranteeing user security by video monitoring in prior art, must keep a close watch in real time display and just can know whether safety of user, when finding that accident or loss appear in the user, be after a period of time, missed the best rescue technical matters on opportunity.
The embodiment of the present invention is achieved in that a kind of method of reporting to the police according to sound source, said method comprising the steps of:
Prerecord the first sound source of sound, the acoustic feature of analyzing described first sound source of sound is determined the parameters,acoustic of described first sound source of sound, and described parameters,acoustic comprises: waveform, fundamental frequency, loudness of a sound, the duration of a sound and the rate of articulation; Set 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 of sound, the corresponding parameters,acoustic of first sound source of sound and each parameters,acoustic is stored as first sound source of sound information;
Record 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, search the corresponding first sound source of sound of second sound source of sound information, namely the parameters,acoustic of the parameters,acoustic of described second sound source of sound and described first sound source of sound 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, 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 surpass parameters,acoustic and second sound source of sound duration to reach second sound source of sound duration alarming threshold value, report to the police.
Another purpose of the embodiment of the present invention is to propose a kind of system that reports to the police according to sound source, and described system comprises: the module of pre-recording, faithful record module, alarm module;
The module of pre-recording, be connected with faithful record module, be used for prerecording the first sound source of sound, the acoustic feature of analyzing described first sound source of sound is determined the parameters,acoustic of described first sound source of sound, and described parameters,acoustic comprises: waveform, fundamental frequency, loudness of a sound, the duration of a sound and the rate of articulation; Set 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 of sound, the corresponding parameters,acoustic of first sound source of sound and each parameters,acoustic is stored as first sound source of sound information;
Faithful record module, module is connected with alarm module with pre-recording, be used for recording 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, search the corresponding first sound source of sound of second sound source of sound information, namely the parameters,acoustic of the parameters,acoustic of described second sound source of sound and described first sound source of sound compares respectively;
Alarm module, be connected with faithful record module, there are two or more to reach the alarming threshold value of parameters,acoustic if be used for the parameters,acoustic of judgement second sound source of sound, 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, report to the police.
Beneficial effect of the present invention:
The present invention is by prerecording the first sound source of sound, the parameters,acoustic of the first sound source of sound in definite situation that needs 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 of sound 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, 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 make up, solved and there is no sound when guaranteeing user security by video monitoring, must keep a close watch in real time display and just can know whether safety of user, when finding that accident or loss appear in the user, be after a period of time, miss the best rescue technical matters on opportunity.
