Description
Technical field
The present invention relates to technical field of electronic equipment, more particularly to a kind of electric light acoustic control based on sound groove recognition technology in e is opened
Pass, control system and method.
Background technology
The light switch installed and used in our existing daily lifes is mostly manually operable, and installs and compare at home
Obvious place, to open and close.This traditional light switch is no doubt very convenient in normal person's use, but for family
The people or the elderly for having legs and feet inconvenience will can then feel difficult by manual operation, or on pitch-dark, the not long ground opened
The places such as lower room or garage, it is desirable to which finding switch unlatching electric light just becomes very difficult.Then, electricity is controlled using audio-switch
The unlatching of lamp appears in daily life.There are two types of existing audio-switch control mode is general:
First, when sound transducer receives voice signal, controller controls audio-switch action, makes audio-switch
It is closed, electric light connects external power supply by the audio-switch of closure and powers to electric light.This control mode is easy by external rings
The interference in border, it is difficult to judge that voice signal is noise or effectively controls signal, often having sound electric light occur will light,
This is undoubtedly a kind of waste of energy for opening by mistake electric light.
Another way is when sound transducer receives voice signal, and controller first carries out the rhythm of voice signal
Judge, if rhythm meets preset condition, then controls audio-switch action.This mode can be certain compared with former control mode
Maloperation is reduced in degree, but this mode is still difficult to effectively judge that voice signal is noise or effectively controls signal.
When ambient noise or back drop are sent out just close to the rhythm sound of preset condition, it is still easy to cause maloperation, it cannot be accurate
Electric light is opened on ground, causes waste electric energy.
Invention content
Based on this, it is necessary to cannot accurately control electric light unlatching for existing electric light audio-switch and control effect is poor
The problem of, a kind of electric light audio-switch, control system and method based on sound groove recognition technology in e are provided.
For this purpose, the specific technical solution that the present invention uses is:

A kind of electric light audio-switch control method based on sound groove recognition technology in e, the control method is to pass through Application on Voiceprint Recognition
Technology identifies the vocal print of user, controls closure and the disconnection of relay by wireless bluetooth device if voice print matching success,
And then the method for realizing light switch, include the following steps:
S1 acquires acoustic information;
S2, the pretreatment of acoustic information carry out the acoustic information acquired in S1 the normalization of vocal print pretreatment and vocal print
Processing;
S3, the extraction of vocal print feature value, to treated in S2, vocal print feature value extracts;
S4, the matching of vocal print feature value carry out the vocal print feature value extracted in S3 with the vocal print feature value kept in advance
Compare, if vocal print feature value successful match, bluetooth equipment to is sent output signal by decoder;
S5, the closure of the bluetooth equipment output control signal control relay and disconnection, and then realize the opening of electric light
With closing.
Further, acoustic information is acquired by microphone in the step S1.
Further, the preprocessing process of sound includes quantization, preemphasis and windowing process in the step S2.
Further, the vocal print feature value kept in advance in the step S4 is that the user acquired by microphone is said
Fixation sentence, and be stored in the memory of host.
Further, the host further includes CPU, the vocal print feature for matching the vocal print feature value with keeping in advance
Value.
Further, the bluetooth equipment includes bluetooth transmitters and Bluetooth Receiver, and the bluetooth transmitters send out letter
Number give Bluetooth Receiver, after the Bluetooth Receiver receives signal, make CPU export digital signal pass through decoder generate one
Kind low and high level signal, the closure of the low and high level signal control relay and disconnection.
The beneficial effects of the invention are as follows:
A kind of electric light audio-switch, control system and method based on sound groove recognition technology in e provided by the invention, exist first

Signal, the closure of the low and high level signal control relay and disconnection.
Specifically, the relay in the above method can have multiple, different electric lights is controlled respectively;It is previously stored in
Vocal print in memory can be the vocal print of multiple users, such as each kinsfolk.
Specifically, before the use, user speaks against microphone first, such as " bedroom lamp is opened, parlor lamp is opened, opens kitchen
Room lamp " etc., and these voice messagings are stored in the memory of host and build up audio database;Lower user is met again to Mike
Wind is spoken, and then to the pretreatment of acoustic information, voiceprint is done normalized, to improve the stability of analysis, then
Preemphasis is carried out to improve high frequency section;Next vocal print feature value is extracted, passes through mould after extraction vocal print feature value
Vocal print feature value (analog signal) is converted into digital data transmission and passed analog-digital converter to the CPU of host, CPU by number converter
The defeated digital signal to come is previously stored in the vocal print in memory and is matched, and finds corresponding user, collected sound
Some the user's voice print matching success stored in signal and memory, then bluetooth transmitters generation signal is blue to Bluetooth Receiver
After tooth receiver receives signal, host will generate a kind of low and high level control signal on connection circuit, arrange relay
It is closed when receiving high-level control signal, then circuit turn-on, opens electric light;When relay receives low level control signal
It disconnects, circuit disconnects, then electric light is closed.
Voice recognition process in said program is the acquisition firstly the need of user's vocal print signal, then carries out vocal print feature
The extraction of value, then the voiceprint of user is stored into memory, then the process of voice print matching is carried out, matched result can
It is shown on a touch-screen display with connection.
Voice print matching process in said program is mainly to carry out identification to user using sound groove recognition technology in e, and incite somebody to action
Voiceprint is associated with relay foundation, generates mapping, and directly light switch is controlled by the vocal print of oneself to reach user.
The logic control of circuit is that vocal print collector acquires user voice information in said program, is used after treatment
The vocal print waveform signal at family, extraction vocal print feature (analog signal) are converted into digital data transmission to master by analog-digital converter
CPU in machine handles voice print matching, after successful match, after bluetooth transmitters send out signal, and after Bluetooth Receiver receives signal,
So that the digital signal that CPU is exported is passed through decoder and generates a kind of low and high level control signal, height electricity in some output channel
Flat control signal can control relay conducting and disconnect, to control electric light.
Voiceprint in said program sends and receives the transmission that process is voiceprint and relies on bluetooth transmitters, vocal print
Bluetooth recipient is leaned in the reception of information.If Bluetooth Receiver receives signal 1, electric light is with regard to shinny;If bluetooth recipient connects
Signal 0 is received, electric light just extinguishes, and such user is achieved that the wireless control to electric light.
Multiple relays can be set in said program, and each relay controls the electric light of not chummery, it can be achieved that not having sexual intercourse
Between electric light individually control, it is easy to use.
It should be understood that the part not illustrated in specification is the prior art or common knowledge.The present embodiment is only used
It in the explanation invention, rather than limits the scope of the invention, the equivalent replacement that those skilled in the art are the present invention
Equal modifications are deemed to fall in invention claims institute protection domain.
