Description
Technical field
The present invention relates to speech recognition technologies, and in particular to a kind of air-conditioning control system based on abnormal speech identification
And its control method.
Background technique
With the improvement of living standard of people, summer is using fan or air-conditioning come more and more general the case where helping body temperature lowering
Time, but fan or air-conditioning is used for a long time, and the generation of the diseases such as cat fever for easily causing human body.And these diseases exist
At the initial stage of generation, there are some symptoms to occur, is not easy to be perceived by patient itself very much.
Speech recognition technology is widely used at present in the intelligent control of household electrical appliances, however in the prior art, people are past
Toward household electrical appliances are controlled just with voice command, lack the active regulating measure of household electrical appliances.
Based on this, if can be automatically right according to abnormal speech of the user when there is disease using speech recognition technology realization
The state of fan or air-conditioning is adjusted, then user experience can be improved.
Summary of the invention
The technical problems to be solved by the present invention are: providing a kind of air-conditioning control system based on abnormal speech identification
And its control method, the speech recognition technology of traditional technology is solved in the application of household electrical appliances, is controlled just with voice command
Household electrical appliances, the problem of lacking the active regulating measure of household electrical appliances.
The technical proposal adopted by the invention to solve the above technical problems is that:
Air-conditioning control system based on abnormal speech identification, comprising:
Voice recognition unit, including microphone module and speech recognition module, the microphone module receive in room
Voice signal sends speech recognition module to after being AD converted, the speech recognition module is based on speech recognition configuration file pair
Voice signal after AD conversion is identified, by calling call back function to notify control unit after identifying successfully；
Control unit, for starting voice recognition unit after system boot, and to its registration for receiving monitoring state
The call back function of variation controls unit of warning according to control strategy after the identification for receiving voice recognition unit successfully notifies
Prompt of warning is carried out, while sending corresponding control command control execution unit to execution unit and executing corresponding actions；
Execution unit, for executing corresponding actions in the corresponding control command for receiving control unit；
It warns unit, for carrying out prompt of warning to user under the control of the control unit；
Abnormal speech corpus is trained the abnormal speech and obtains speech recognition ginseng for storing abnormal speech
Number is supplied to the speech recognition configuration file of speech recognition module.
As advanced optimizing, the abnormal speech includes the characterization body such as the sound of sneezing and/or the sound to wipe away one's snivel
The voice of body abnormal state.It may determine that abnormality occurs in the body of user by these abnormal speeches.
As advanced optimizing, the abnormal speech corpus specifically use deep learning algorithm to the abnormal speech into
Row training.Deep learning algorithm is current mainstream algorithm, has the accurate advantage of training.
As advanced optimizing, the unit of warning includes LED lamp module and/or buzzer module.It is carried out by LED light
Flashing indicating carries out auditory tone cues by buzzer module.
As advanced optimizing, the control strategy are as follows: the multiple grades of warning of setting, each grade of warning are one corresponding
Trigger condition and control program to execution unit, when reaching corresponding trigger condition, enable it is corresponding warns, simultaneously
Corresponding actions are executed according to corresponding control program control execution unit.
By the setting of multiple grades of warning, can be carried out according to the actual monitoring situation of the abnormal speech to user corresponding
Grade warn and the corresponding control to execution unit, it is more flexible.
As advanced optimizing, the original state of the voice recognition unit on startup is unidentified state, is being identified
After success, state is switched to identification state, at this time by calling call back function to notify control unit；Described control unit is being prolonged
The identification state of voice recognition unit is discharged after slow certain time interval.By the variation detection of status indicator convenient for control
Unit knows voice recognition unit to the identification situation of abnormal speech, to accordingly be warned in time and to execution unit in time
Control.And it is to influence user in order to avoid continuously sending out and warning that delay certain time interval, which are arranged, to discharge identification state again
Life.
As advanced optimizing, the execution unit is fan or air-conditioning, and the execution corresponding actions include: control fan
Revolving speed or switch, control temperature, switch or the air outlet angle of air-conditioning.When judging that user's body occurs abnormal, by wind
The corresponding control of fan or air-conditioning can improve user experience to avoid user's aggravation.
In addition, the present invention also provides a kind of control methods applied to above-mentioned air-conditioning control system comprising with
Lower step:
A. acoustic recognition unit identifies the voice signal in room, if being identified as abnormal speech, passes through calling
Call back function notifies control unit；
B. control unit receives and warn mentioning according to control strategy control unit of warning after the notice of acoustic recognition unit
Show, while sending corresponding control command control execution unit to execution unit and executing corresponding actions.
As advanced optimizing, in step a, the original state of the voice recognition unit on startup is unidentified shape
State, after identifying successfully, state is switched to identification state, at this time by calling call back function to notify control unit；Step b
In, described control unit discharges speech recognition after postponing certain time interval after receiving the notice of acoustic recognition unit
The identification state of unit.
Knowledge of the voice recognition unit to abnormal speech is known in time by the variation detection of status indicator convenient for control unit
Sorrow of separation condition, to accordingly be warned in time and the control to execution unit.And delay certain time interval are set and are discharged again
Identification state is to influence the life of user in order to avoid continuously sending out and warning.
As advanced optimizing, in step b, the control strategy are as follows: the multiple grades of warning of setting, each grade of warning
A corresponding trigger condition and the control program to execution unit enable corresponding when reaching corresponding trigger condition
It warns, while corresponding actions is executed according to corresponding control program control execution unit.
By the setting of multiple grades of warning, can be carried out according to the actual monitoring situation of the abnormal speech to user corresponding
Grade warn and the corresponding control to execution unit, it is more flexible.
The beneficial effects of the present invention are: by being monitored to the voice signal in room, in the exception for identifying user
When voice (such as sneeze, put nasal mucus on the skin), prompt of warning is carried out, while controlling the execution units such as air-conditioning or fan and executing corresponding move
Make (such as: reducing rotation speed of the fan perhaps closes fan improve air-conditioner temperature, adjustment air outlet angle or closing air-conditioning etc.) to avoid
Sb.'s illness took a turn for the worse by user, and the active for being achieved in household electrical appliances is adjusted, and improves user experience.
Detailed description of the invention
