A kind of controller based on voice array
Technical field
This utility model relates to intelligent home voice and controls technical field, especially relates to a kind of based on voice
The controller of array.
Background technology
Along with the fast development of technology of Internet of things, the Smart Home life having come into people slowly, intelligence
Controlling as the most crucial part of Smart Home of household, its development more attracts people's attention.Traditional intelligence
The control of household is that the both hands by people go to realize the control to controllable device, still cannot break away from manually behaviour
Control controls the yoke of terminal, and therefore, people are more desirable to realize the control to controllable device by voice.
Compared with traditional manual control mode, the advantage of speech recognition controlled mode maximum is just through sound
All of equipment can be controlled, change invisible for tangible, and action can be particularly suitable for distant control
Inconvenience and the user of pursuit high-quality life staying idle at home.But existing Voice command mode needs by intelligence
Energy wearable device or other recording device, therefore, people more need one can break away from intelligence wearing
Equipment or other recording devices realize the Based Intelligent Control to controllable device.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of controller based on voice array so that user
Only need to stand in array region " to open one's mouth " and just can control household appliances.
The technical solution adopted in the utility model is: a kind of controller based on voice array, its feature exists
In: include that voice typing module, embedded MCU, communication module, memory module, control command are defeated
Going out module, described voice typing module, communication module, memory module, control command output module are respectively
Being connected with described embedded MCU, described voice typing module uses mike linear array acquisition language
Sound data, described memory module is used for storing default control key word, and described embedded MCU is to described
Speech data is identified and according to described default control key word transmitting control commands, described control command
Output module exports described control command.
Further, described voice typing module also includes noise reduction process module, for being gone by wave filter
Except the clutter in described speech data.
Further, sound identification module, described sound identification module it are provided with in described embedded MCU
Described speech data is identified as phonetic data.
Further, described communication module is connected with cloud server, and described cloud server is provided with language
Sound identification storehouse.
Further, described phonetic data translation is become by described cloud server according to described speech recognition library
Command information.
Further, being additionally provided with matching module in described embedded MCU, described matching module is used for will
Described command information is mated with described default control key word, and sends described control command to described
Control command output module.
Further, described controller also includes power management module, and described power management module is with described
Embedded MCU is connected.
This utility model has the advantage that with good effect: by the sound of voice array typing user,
It is not required to use Intelligent worn device or other recording devices, only needs subscriber station just can pass through voice in array area
Control family's controllable electrical appliance;Speech recognition, based on cloud server, has faster recognition rate, higher
Accuracy rate.

Detailed description of the invention
In order to be better understood from this utility model, below in conjunction with specific embodiments and the drawings to this utility model
Conduct further description.
With reference to Fig. 1 and Fig. 2, the technical solution adopted in the utility model is: a kind of based on voice array
Controller, it is characterised in that: include voice typing module, embedded MCU, communication module, storage
Module, control command output module, voice typing module, communication module, memory module, control command
Output module is connected with embedded MCU respectively, and voice typing module uses mike linear array to adopt
Collection speech data, memory module is used for storing default control key word, and embedded MCU is to speech data
Being identified and according to default control key word transmitting control commands, the output of control command output module controls
Order.
Preferably, voice typing module uses 5 microphone arrays to gather speech data, voice typing module
Also include noise reduction process module, for being removed the clutter in speech data by wave filter.Embedded MCU
Inside being provided with sound identification module, speech data is identified as phonetic data by sound identification module.Communication module
Being connected with cloud server, cloud server is provided with speech recognition library.Cloud server is known according to voice
Phonetic data translation is become command information by other storehouse.It is additionally provided with matching module in embedded MCU, mates mould
Block transmitting control commands after command information being mated with default control key word, the match is successful is given
Control command output module.
Controller also includes power management module, and power management module is connected with embedded MCU, can
To provide power supply to controller.
With reference to Fig. 3, work process of the present utility model: this utility model provides a kind of based on voice array
Controller operationally, user need not use Intelligent worn device or other recording devices, only needs station
In 5 microphone array column regions, send sound, such as " turning on light ", pickup will be formed in the front of user
Wave beam, can suppress the noise outside pickup and reflected sound, 5 microphone arrays to gather pickup wave beam conduct
The speech data of user, carries out further noise reduction process through noise reduction process module to speech data, removes
Clutter in sound, then by the sound identification module in embedded MCU to the voice after noise reduction process
Data are identified, and as being identified as phonetic data " kaideng ", phonetic data are led to by sound identification module
Crossing communication module and be transferred to cloud server, cloud server is by the phonetic data received and speech recognition
Data in storehouse compare, the data that the phonetic data that recall and receive are the most close, and by this
Data is translated into command information and is sent to sound identification module, by sound identification module again by command information
Being transferred to matching module, it is crucial that matching module reads the default control in memory module according to command information
Word, finds the control instruction matched with command information, and sends control instruction and export mould to control command
Block, is exported this control instruction to control corresponding controlled plant by control command output module.
More than show ultimate principle of the present utility model, principal character and advantage of the present utility model.This
Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, above-described embodiment
With description described in ultimate principle of the present utility model is simply described, without departing from this utility model essence
On the premise of god and scope, this utility model also has various changes and modifications, and these changes and improvements are all
Within falling into the patent covering scope of claimed this utility model scope.This utility model claims
Scope is defined by appending claims and equivalent thereof.
