There is the pronunciation microphone and falls the microphone of making an uproar at rubbing crusher operation end, the pronunciation microphone is monitored around the sound of 5 meters within ranges at the moment, it monitors the sound of machine within ranges itself to fall the microphone of making an uproar, generally add 0.5 meters for the machine size, sound passes through signal processing module and changes into digital signal, wherein fall the microphone record normal noise of making an uproar, rubbing crusher noise of oneself promptly, and change into the audio frequency of eliminating corresponding noise through noise processing module, play through falling the speaker of making an uproar, this audio frequency can offset each other with the noise, let the noise disappear basically, other end speech command signal carries out identification analysis through speech recognition module, send the executive command through function execution module after the discernment affirmation and give rubbing crusher function piece, report the speaker simultaneously and report the execution condition.
The voice control flow of the system is as follows:
the user may wake up the device with a voice, such as "pink, |! After inputting the corresponding command, the voice microphone receives the voice analog signal and converts the voice analog signal into a digital signal through the signal processing module;
the digital signal is transmitted to a voice recognition module for voice recognition and command matching, if the matching finds that the matching is unsuccessful without the functional instruction and the like, the voice feeds back that the function is not available, please speak the request again, and then the voice microphone is awakened again for monitoring, if the matching is successful, the function execution module outputs an execution command, and the execution command comprises the following commands:
(1-1) basic function:
1-1-1) starting and closing functions, and starting and closing a pulverizer;
1-1-2), the gear setting of the crusher, such as basic gear 1, 2 and the like, special gear straw crushing and the like;
1-1-3) time function. The duration of operation of the pulverizer, etc.;
(1-2) entertainment function
1-2-1) multimedia functions, offline U-disk music, online FM, online music, etc
1-2-2) telephone function, Bluetooth telephone, and can be used for answering without mobile phone
1-2-3) other entertainment functions such as voice games, weather queries, smart communications, and KTV singing.
2. As shown in fig. 3, the noise reduction process of this system is as follows:
2-1) after the pulverizer is started, starting a noise reduction microphone, wherein the noise reduction microphone only receives the sound within the range of 0.5 m added to the maximum size of the pulverizer, and converting the continuously received sound in real time through a signal processing module;
2-2) the noise processing module analyzes the noise degree, can be preset to 40 decibels, and when the noise exceeds 40 decibels, the noise processing module makes a noise reduction audio frequency in a mode of converting the amplitude of the audio wave up and down, and plays the audio in real time through a noise reduction loudspeaker during making so as to offset the noise.
2-3) the user controls the function of the pulverizer by voice, and the voice recording range of the noise reduction microphone is within 0.5 meter from the device generally, so that the voice recording range has no influence on each other. After the noise reduction system processes the noise, the environment of the pulverizer is quiet, the voice command cannot be greatly interfered, and the voice command of a user is better recognized.
Advantageous effects
1) The voice controls the basic function, can liberate both hands;
2) the pulverizer system is internally provided with an entertainment function, plays music, small products and other programs, and is not tired any more in the working process;
3) the special noise reduction system enables the pulverizer to normally recognize voice commands in a complex noise environment.
The reason is as follows:
