Problems solved by technology

[0003] The purpose of the embodiments of the present invention is to propose a method of alarming according to the sound source, aiming to solve the problem that in the prior art, when the user is safe through video monitoring, there is no sound, and the user must be stared at the display in real time to know whether the user is safe. Or lost, it's been a while, a technical problem of missing the best time to save

Embodiment 1

[0019] figure 1 A flow chart of a method for alarming according to a sound source in an embodiment of the present invention, the method includes the following steps:

[0020] S101, pre-recording the first sound source, analyzing the acoustic characteristics of the first sound source to determine the acoustic parameters of the first sound source, the acoustic parameters include: waveform, fundamental frequency, sound intensity, sound length and pronunciation speed; set the alarm threshold value of each acoustic parameter and the alarm threshold value of the second sound source duration, and use the first sound source, the corresponding acoustic parameter of the first sound source and the alarm threshold value of each acoustic parameter as the first sound source A sound source information is stored;

[0021] The first sound source is a word or cry that the user has a high probability of uttering in an emergency and can identify acoustic parameters, and according to the first so...

Embodiment 2

[0039] figure 2 It is a structural schematic diagram of an alarm system based on a sound source according to an embodiment of the present invention.

[0040] The system includes: a pre-recording module, a real recording module, and an alarm module;

[0041] The pre-recording module is connected with the actual recording module, and is used for pre-recording the first sound source, analyzing the acoustic characteristics of the first sound source to determine the acoustic parameters of the first sound source, and the acoustic parameters include: waveform, basic Frequency, sound intensity, sound length and pronunciation speed; set the alarm threshold value of each acoustic parameter and the alarm threshold value of the duration of the second sound source, and set the first sound source, the corresponding acoustic parameters of the first sound source and each The alarm threshold value of an acoustic parameter is stored as the first sound source information;

[0042] The first s...

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 keepa 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 [0001] The invention relates to the technical field of acoustics, in particular to a method and system for alarming according to a sound source. Background technique [0002] There are a lot of missing children now, if you don’t pay attention to children, they will be lost, a family will be devastated, bankrupt, and more parents will be mentally disturbed; in recent years, there have been many vicious and violent incidents in schools, causing many parents to ask questions Check whether the school has monitoring equipment such as "electronic eyes" and "global eyes". Parents hope that they can monitor their children's conditions in real time through the Internet and mobile Internet, but this kind of video monitoring has no sound. Whether it is safe, when the child is found to be accidental or lost, it has been a period of time, and the best time to save is missed. Contents of the invention [0003] The purpose of the embodiments of the present invention is t...
