Under the circumstance of taking voice controlling, the control is promptness, and recognition rate is high.
Description
Affiliated technical field
The present invention relates to a kind of electric system, specifically reference and a kind of system that can control electrical equipment by voice.
Background technology
The electric system that has voice control function at present begins to occur, because control operation is convenient, therefore has vast market prospect.General technical scheme is to adopt microphone to pick up the voice control signal, amplifies by amplifier then, again the signal after this amplification is carried out voice recognition processing, produces telecommand at last main frame is controlled.Existing technical scheme is to reach user mode to one or more main frames (as air-conditioning, refrigerator etc.) of sounding not, but the main frame sounding is often arranged in actual environment for use, so they are difficult to apply.Because if a main frame sounding is arranged in controlled main frame sounding or a plurality of main frame, the voice signal that sends of voice control signal and main frame will mix so, and the probability of speech recognition will reduce greatly, causes the malfunctioning or misoperation of control at last.
Summary of the invention
Purpose of the present invention just provide a kind of can be to sounding or sounding main frame not, or have one or more not sounding main frames to carry out voice-operated electric system again to existing sounding main frame, make control quicker, accuracy is higher.
When realizing purpose of the present invention, taked following technological means:
In this voice control apparatus system, comprise main frame 1 and voice controller 2 two parts.
In main frame 1, if this main frame 1 is the sounding main frame, its sound signal promotes loudspeaker 4 sounding by power amplifier 3 on one side so, by audio wireless transmitter 5 outwards launch on one side; If this main frame 1 is sounding main frame not, just do not increase this circuit.
In voice controller 2, the wireless signal that 10 pairs of audio wireless transmitters 5 of audio wireless receiving demodulation device send carries out signal reception, demodulation, sends into canceller 14 after amplifying through AGC amplifier 2 13 again; Voice control signal and main frame 1 are all picked up by microphone 8 by the voice signal that loudspeaker 4 outwards sends simultaneously, amplify by AGC amplifier 1 then, and the signal after the amplification is also sent into canceller 14; Canceller 14 carries out voice recognition processing by speech recognition device 15 after these two kinds of signals are offseted processing again, produces an identification signal.This identification signal produces a steering order by order number controller 16, this steering order becomes wireless control signal through audio wireless transmitter 17 again and outwards launches, after remote signal receiver 6 in the main frame 1 receives this remote signal, send into the central processing unit 7 of main frame 1 and decipher out steering order, implement control.
For existing sounding main frame in the environment for use, again the voice control apparatus system of one or more not sounding main frames is arranged, technical scheme is also identical, and the wireless remote control signal that sends of voice controller, through deciphering out telecommand, can control All hosts.
Because in the present invention, through behind the canceller, the sound that the sounding main frame sends will be offseted, and not the sounding main frame to not influence of the work of voice controller, therefore the problem that the voice signal that offers speech recognition mixes with regard to the voice signal that does not have voice control signal and main frame and send, the probability of speech recognition will improve greatly, thereby makes the control of voice control apparatus system quicker, and accuracy is higher.
Description of drawings
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a present embodiment electricity theory diagram.
Embodiment
In Fig. 1, this voice control apparatus system comprises main frame 1 and voice controller 2 two parts.
In main frame 1, this main frame 1 is the sounding main frame, and its sound signal promotes loudspeaker 4 sounding by power amplifier 3 on one side, by audio wireless transmitter 17 outwards launch on one side.
In voice controller 2, audio wireless receiving demodulation device 10 receives the signal that audio wireless transmitter 5 is launched, and sends into time-delay 11 and reverberation 12 earlier to delay time/the reverberation processing, sends in the canceller 14 after AGC amplifier 2 13 amplifies.On the other hand, voice control signal and main frame 1 are all picked up by microphone 8 by the voice signal that loudspeaker 4 outwards sends, and amplify by AGC amplifier 1 then, and the signal after the amplification is also sent into canceller 14; Canceller 14 offsets processing to these two kinds of signals, and the sound that sends of main frame will be offseted like this, the problem that the voice signal that therefore offers speech recognition mixes with regard to the voice signal that does not have voice control signal and main frame and send; The output signal of canceller 14 is discerned processing by speech recognition 15, produces an identification signal.This identification signal produces a steering order by order number controller 16, this steering order becomes wireless control signal through audio wireless transmitter 17 again, after remote signal receiver 6 in the main frame 1 receives this wireless control signal, send into the central processing unit 17 of main frame 1 and decipher out steering order, main frame just can carry out work according to the control corresponding instruction.
In the present embodiment, for the time delay of time-delay 11 and the reverberation depth parameter of reverberation 12, the user can regulate according to environmental factor, so just makes the better effects if of signal cancellation, and is stronger to the adaptability of environment.
If main frame 1 is sounding not, in main frame 1, just need not increase top this audio frequency radiating circuit so.2 of voice controllers do not change.At this moment in voice controller 2,, there is not signal output because audio wireless receiving demodulation device 10 can not receive signal yet.When not having the voice control signal, microphone 7 does not have signal output yet, so yet not output of canceller 14, is equivalent to signal and is offseted, and the main frame that is to say sounding does not influence the work of voice controller 2.When the voice control signal occurs, canceller 14 output the voice control signal only arranged, voice-operated like this effect is also fine.
For the voice control apparatus system that contains a sounding main frame, one or more not sounding main frames, because the main frame of sounding is not to the not influence of work of voice controller, therefore technical scheme is also identical, and the corresponding telecommand of sending can be controlled All hosts.
Audio wireless emission and remote signal emission can be adopted infrared mode, also can adopt wireless system, and its receiving unit is also undertaken supporting by corresponding manner certainly.
