Summary of the invention
In order to overcome the above problem, the present invention provides a kind of wearable intelligent alarm systems, can automatically in time
Sending alarm system.
To achieve the above object, present invention provide the technical scheme that
A kind of intelligent alarm system, including Compare System, judge system, retain system and alarm system;The reservation system packet
It includes and records module and the first memory module, be preset in the first memory module to comparative information, include sound letter to comparative information
Breath and physiological reaction information;Acoustic information and wearer's physiological reaction information in the Compare System acquisition environment, and be transferred to
Judgement system;The judgement system will receive information and be compared with the first memory module to comparative information, and judge whether
Send a signal to alarm system;The alarm system according to judge system send signal issue alarm;The judgement system meets
Alarm system is sent a signal to after the following conditions:
1) in the comparing result for judging system, received acoustic information judges system with when having differences wait compare acoustic information
Send a signal to alarm system alarm;
2) in the comparing result for judging system, received physiological reaction information and when being had differences wait compare physiological reaction information,
Judgement system sends a signal to alarm system alarm.
The physiological reaction information includes heart rate information, blood pressure information, pulse information.
The judgement system has following two judgment model:
1) sound comparison is carried out by tonal variations, loudness variation, tone color variation;
2) it is compared by sound and analyzes and determines in acquisition sound whether include dangerous information.
The dangerous information includes calling for help sound.
The sound compare analysis the following steps are included:
1) Compare System acquires sample sound, and is filtered amplification to the acoustic information of acquisition, is sent to judgement system;
2) judgement system pre-processes sample sound, and extracts mel-frequency cepstrum coefficient and corresponding short-time energy spy
Sign;
3) the mel-frequency cepstrum coefficient of extraction and corresponding short-time energy feature are trained using Adaboost method;
4) parameter after above-mentioned training is identified, whether to determine in acoustic information comprising calling for help sound.
It is additionally provided with the second memory module in the reservation system, records module and connect with the second memory module, described the
Two memory modules, which are used to store, records the information that module is recorded.
Above-mentioned technical proposal has the beneficial effect that
The present invention provides a kind of intelligent alarm systems, can issue rescue alarm letter when user faces a danger fortuitous event
Breath, especially user fall into a coma or when automatisms, can also issue alert help information automatically, when obtaining best rescue
Between, the incidence of tragedy can be greatly lowered.
Technical solution of the present invention is clearly and completely described below in conjunction with specific embodiment, it is clear that retouched
The embodiment stated is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field
Those of ordinary skill's every other embodiment obtained without making creative work, belongs to protection of the present invention
Range.
Embodiment 1
A kind of intelligent alarm system, including Compare System, judge system, retain system and alarm system;The reservation system packet
It includes and records module and the first memory module, be preset in the first memory module to comparative information, include sound letter to comparative information
Breath and physiological reaction information;Acoustic information and wearer's physiological reaction information in the Compare System acquisition environment, and be transferred to
Judgement system;The judgement system will receive information and be compared with the first memory module to comparative information, and judge whether
Send a signal to alarm system;The alarm system according to judge system send signal issue alarm;The judgement system meets
Alarm system is sent a signal to after the following conditions:
1) in the comparing result for judging system, received acoustic information judges system with when having differences wait compare acoustic information
Send a signal to alarm system alarm;
2) in the comparing result for judging system, received physiological reaction information and when being had differences wait compare physiological reaction information,
Judgement system sends a signal to alarm system alarm.
The physiological reaction information includes heart rate information, blood pressure information, pulse information.
The judgement system has following two judgment model:
1) sound comparison is carried out by tonal variations, loudness variation, tone color variation;
2) it is compared by sound and analyzes and determines in acquisition sound whether include dangerous information.
The dangerous information includes calling for help sound.
The sound compare analysis the following steps are included:
1) Compare System acquires sample sound, and is filtered amplification to the acoustic information of acquisition, is sent to judgement system;
2) judgement system pre-processes sample sound, and extracts mel-frequency cepstrum coefficient and corresponding short-time energy spy
Sign;
3) the mel-frequency cepstrum coefficient of extraction and corresponding short-time energy feature are trained using Adaboost method;
4) parameter after above-mentioned training is identified, whether to determine in acoustic information comprising calling for help sound.
It is additionally provided with the second memory module in the reservation system, records module and connect with the second memory module, described the
Two memory modules, which are used to store, records the information that module is recorded.
