With reference to Fig. 3, specifically, described step " gather and analyze the audio frequency of pre-set space, different in audio frequency collection is detected
Chang Shi, opens video acquisition " include：
S210, collection original analog audio, are converted to pulse-code modulation format audio；
S220, the noise filtering in pulse-code modulation format audio, then carry out quiet detection and obtain mute state threshold value；
S230, the audio frequency of collection is compared with described mute state threshold value, exceedes in the audio amplitude collecting quiet
During sound state threshold, video acquisition is carried out to pre-set space.
It should be noted that in step S210, the AndroidRecord that television set passes through to carry carries out adopting of sound
Collection, and collection analogue audio frequency is converted into PCM ((Pulse Code Modulation, PCM) form, i.e. pulse-code modulation form sound
Sound data.
In step S220, reject noise, mainly background sound and echo in original audio by using WebRTC, from
And obtain the sound of " clean ".Sound to " clean " obtaining, by WebRTC VAD module to carrying out quiet detection, obtains
Mute state threshold value.
In step S230, according to mute state threshold value, judge whether the audio frequency gathering is abnormal, abnormal sound is such as detected
Frequently, then open video acquisition.
Quiet detection technique, through development for many years, has had much ripe quiet detection technique to put into actually used
In, quiet detection algorithm is usually to utilize the voice and noise difference in characteristics of signals, is extracted by computed in software method
These eigenvalues and being contrasted with certain threshold value, to carry out quiet judgement, and conventional detection has short-time energy to detect, high
This detection, adaptive energy detects, the mode such as correlation detection.
Because voice and the multiformity of noise, in the case that particularly environmental noise is more complicated, single quiet detection is calculated
The effect of method is not fine.So, the technical program combines the characteristic of several algorithms, is carried out using a kind of composite algorism
The function of quiet detection.Composite algorism includes two parts, adaptive energy detection and linear prediction model detection.Adaptive should be able to
Using voice and noise, the difference on energy is detected quantity algorithm, and the energy of usual voice is greater than the energy of noise,
By the energy of comparator input signal and the size of speech energy threshold value, to judge whether the signal inputting is voice.Linearly pre-
Survey model algorithm by linear forecasting technology come the linear forecasting parameter of signal calculated model, because background noise is typically all flat
Steady stochastic signal, so, quiet or voice can be judged by the change of linear forecasting parameter.Although adaptive energy
Detection algorithm complexity is relatively low, and detection speed is very fast, but bad to the signal detection effect of faint energy.Simultaneously although line
Property forecast model detection complexity higher, detection efficiency is relatively low, and detection time is slower, but the Detection results to faint energy
Preferably.Two kinds of algorithms being combined, first carrying out speech detection using the mode of adaptive energy detection, if non-mute shape is detected
State, then be directly judged as cacophonia state, if being detected as mute state, the mode using linear prediction model is being directed to
Faint energy signal carries out one-time detection.Detection efficiency faster so can either be ensured, can guarantee that higher detection is accurate again
Property.
First with reference to Fig. 4, step S200 is further elaborated：
S201, the audio signal of receives input；
S202, by adaptive ability detection judge input signal whether be quiet；
If S203 is judged as YES quiet, then further determined whether as quiet by the change of linear forecasting parameter；
If S204 be judged as quiet, using this quiet as up-to-date mute state threshold parameter, after renewal preserve；
If S205 is judged as non-mute in step S202 and S203, the disposal of gentle filter is made to non-mute；
S206, audio frequency export extremely, wake up video acquisition further and record.
With reference to Fig. 5, specifically, described step " gathers and analyzes the video of pre-set space, scheme in collection video is detected
When the scene changes of picture are abnormal, send warning message to mobile terminal " include：
Adjacent two field pictures are processed, must show up by continuous at least two field pictures respectively in S310, acquisition collection video
Scape changes difference；
S320, the scene changes obtaining difference is contrasted with default scene threshold value, judge to be by recognition of face or
Directly transmit warning message；
If S330 carries out recognition of face, obtain the image that scene changes, carry out recognition of face；Recognizing face
When, send warning message to mobile terminal.
It should be noted that the collection of video is carried out using the V4L2 mode of Linux standard, television set can not affected
In the case of the normal operation of operating system, carry out the collection of video.
In step S310, take in the video of collection continuously several frame image sequence { P1, P2...Pn }, respectively to continuous
Two field pictures carry out processing scene changes difference α obtaining in video.
In step s 320, the scene changes obtaining difference is contrasted with the default scene threshold value in moderator, certainly
Surely it is by recognition of face and still send warning message.
When needing to carry out recognition of face, then image P in the image sequence { P1, P2...Pn } scene changing,
It is sequentially sent to Haar classifier and carries out Face datection, until in image Pi (0<I≤n) in face is detected, or detected all
Image sequence.
Further, " when exceeding pre-conditioned in scene changes collection video is detected, send and report to the police in described step
Information is to mobile terminal " after also include：
S500, preservation collect abnormal audio frequency and video.
It should be noted that in the present embodiment, by SD card recording exceptional state audio frequency local in television set, video counts
According to prevent the unsuccessful situation of alarm call.
In conjunction with Fig. 6, the technical program is further elaborated：
S1, the mobile terminal by being bound with television set, are controlled and open television set unlatching monitoring；
After S2, unlatching monitoring, the audio detection module of television set proceeds by audio recording immediately；
S3, the audio frequency to recording are analyzed detecting；
S4, judge that the audio frequency recorded is whether abnormal；
S5, if so, wake-up video acquisition；If it is not, then continuing recording audio, detected；
S6, carry out video record immediately；
S7, the video to recording are analyzed detecting；
S8, the abnormal image to the scene changes in the video recorded are estimated；
The default scene threshold value of S9, basis, arbitrates to abnormal image；
S10, carry out confirm scene changes image abnormity when, directly transmit alarm to the mobile terminal of user；
S11, when needing to further confirm that whether abnormal, open Face datection；
If S12 has detected face, send alarm to mobile terminal；
If S13 is not detected by face, illustrates that situation without exception occurs, now stop video acquisition, be further continued for carrying out audio frequency
