Detailed description of the invention
Fig. 1 is system structure diagram of the invention.
Specific embodiment
Present invention will now be described in further detail with reference to the embodiments and the accompanying drawings, but embodiments of the present invention are unlimited
In this.
Embodiment
Referring to Fig. 1, in the present embodiment, the triggering information weight reselection procedure optimization system of wearable safety alarm device includes phase
Signal identification model, decision model and the alarm modules of connection;Wherein signal identification model is for receiving and analyzing extraneous offer
Physiological signal and environmental signal, judge the ambient condition and oneself state of wearer;Decision model is used for according to signal identification
The ambient condition and oneself state that model calculates, carry out different weight distributions to signal identification result and provide weighted sum to comment
Point;Alarm modules are used to compare the scoring and preset alarm threshold value that decision model provides, and judge whether to trigger and sound an alarm.Its
In, physiological signal includes pulse wave signal, blood pressure signal and skin electric signal, and environmental signal includes voice signal and acceleration letter
Number.
Signal identification model includes Emotion identification model, tone identification model, keyword recognition mould based on physiological data
Type, Emotion identification model, specific sound identification model, gesture recognition model, moving state identification model, based on physiological data
Emotion identification model judges the oneself state of wearer, tone identification model, keyword recognition model, mood according to physiological signal
Identification model, specific sound identification model judge the oneself state and environmental signal of wearer all in accordance with voice signal, and posture is known
Other model, moving state identification model judge the oneself state of wearer according to acceleration signal.This six kinds of models are using warp
The machine learning algorithm of initial acquisition data set training judges the probability of data fit specified conditions;It is secondary when being judged by accident in use process
When number is more than threshold value, it will use data that initial acquisition data set and Retraining algorithm is added.
Emotion identification model based on physiological data uses training data training machine learning algorithm, and mood is classified as two
Class: smaller negative emotions, neutral mood and all positive moods are classified as one kind, and more negative emotions are classified as another kind of;
Trained model is called when use, judges whether wearer has by analysis pulse wave signal, blood pressure signal and skin electric signal
Larger negative emotions.
Tone identification model exports according to voice signal and has fear in wearer and short distance in the tone of talker
The probability of the property tone and the abusing property tone;Keyword recognition model exports wherein according to voice signal comprising emergency property words and disgrace
The probability of scolding property words;Emotion identification model exports the probability wherein comprising frightened mood according to voice signal;Specific sound is known
Other model exports probability wherein comprising preset specific sound according to voice signal.
Gesture recognition model judges that wearer is in the violent shake, defensive of hand struggle according to acceleration signal
Pat, fall down with acceleration it is excessive or mutation appearance probability of state;It moves identification model and wearer is judged according to acceleration signal
Body movement situation, and export movement severity.
Decision model carries out each data reliability judgement to the result that signal identification model exports, according to varying environment state
Under different weight ratios, scoring is weighted to each result, the scoring after output summation.Power in decision model under varying environment
It again can be by initial data and using the new raw data set of Data Synthesis and to algorithm than after accumulation reaches certain erroneous judgement number
Re -training is carried out, the data weighting ratio under varying environment is updated.
When wearer is in strenuous exercise's state, mesh can be characterized by the collected acceleration signal of three-axis sensor
Preceding wearable device is just in strenuous exercise.The weight distribution algorithm pre-set is called at this time, and weight point is carried out to unlike signal
With processing.Pulse wave signal substantially changes similar, the feelings to the pulse wave signal when mood swing when due to strenuous exercise
The mood result obtained under condition by pulse wave signal is by larger interference, therefore pulse wave signal weight distribution can be transferred to low water
Flat, voice signal (i.e. voice signal) can play a leading role (specific weight value is provided by many experiments analysis) at this time.Other letters
Number and identification model analysis result weight distribution it is similar with its.It determines eventually by the analysis result of weight accounting under the environment
It is fixed whether to trigger warning device.
It is special locating for equipment that the present invention is carried out by the signal (voice signal, acceleration signal) being associated with the external world first
The judgement of environment, according to voice signal obtain facility environment noisy degree, acceleration signal analyze wearer motion state and
Posture, identifies the movement of wearer, and then judges the state of wearer itself;It is called according to the ambient condition of wearable device different
Weight distribution algorithm assigns different weighted values to the contribution degree of various signals, separates main signal and secondary signal, carry out thereafter
Analysis;Different weight distribution algorithms are called according to the ambient condition of wearable device, weight is carried out to each signal identification model
Distribution, i.e., the identification model result be " effective " when, to warning device wake-up percentage contribution score, only score value is total
With warning device can be just triggered when reaching certain numerical value.
