Further detailed description is done to the present invention below with reference to embodiment:
Embodiment one
Sound control output device is applied to driving circuit control lamp switch in the present embodiment.
Acquisition time is set as 2 seconds, acquires the indicator light of beginning as green, until green flashing next time is 2 seconds when starting,
For periodical output optical signal, which is 0.2 second.After user sees green indicator light flashing, use
Family issues the sound instruction of " low short-high short-high long ", i.e., issues one section of duration short bass first, as normal to issue
Sound, the duration, volume was to be used to indicate the yellow indicator lamp that user inputs acoustic segment at this time less than 45db less than 0.4 second
Bright, then, user issues one section of duration short high pitch, and the duration, volume was to use at this time greater than 45db less than 0.4 second
It is bright in the red indicating light that instruction user inputs acoustic segment, finally, user issues one section of duration long high pitch, duration
Greater than 0.4 second, volume be greater than 45db, be used to indicate at this time user input acoustic segment red indicating light is bright and the duration with
High pitch is close to be synchronized.Above-mentioned indicator light belongs to cue module, and cue module control output optical signal instruction user makes a sound
Instruction input sound control output device, acquisition module acquire the sound instruction of user's input.
Then, the parameter for the acoustic information that comparison module receives acquisition module item compared with being stored in memory module
Part is compared.Specifically, acoustic information parameter is sound number of segment, sound segment length, sound intensity here, and comparison condition connects
Whether the acoustic information received is one section of low minor, one section of high minor, one section of high long.Wherein, the judgement of bass and high pitch can
It is determined with preset threshold value, such as it is bass that volume, which is less than 45db, it is high pitch that volume, which is greater than 45db,；The judgement of minor and long
It can be determined with preset threshold value, such as the duration was minor less than 0.4 second, because human normal word speed is 150-300 word, because
And it is easily controlled at 0.2-0.3 seconds；Duration is greater than 0.4 second for long, and the actual duration is to be easily controlled
Lower limit more than 0.4 second or more, by average time 0.3+0.3+0.6 (lasting)+0.2 (scintillation time average value)=1.4 seconds, then
It slightly can control the periodicity acquisition at 2 seconds completely there are the time margin for issuing lag to indicator light reflecting time and sound
In time.
Finally, when comparison module comparison result is that collected sound is consistent with comparison condition at least once, then
Output unit exports corresponding impulse level signal and controls lamps and lanterns opening operation to PWM pulsewidth modulation, such as is exported by single-chip microcontroller
Impulse level makes LED control chip enter fully open state from closed state, so that constant-current circuit be driven to make lamps and lanterns bright light.
As an improvement of the present embodiment, the process of acquisition and output can constantly iterative cycles be operated, such as acquire
Module is with 2 seconds for period continuous service, and green indicator light flashes flashing in every 2 seconds once, in any a cycle, if sound
Output device successful acquisition is controlled to qualified voice input order, then exports corresponding impulse level signal control lamps and lanterns
Implement on or off operation, such as after lamps and lanterns bright light, user requires to close lamps and lanterns, then need to only complete in subsequent collection period
Voice command input, then corresponding output reversion close its output control lamps and lanterns and turn off the light.
As an improvement of the present embodiment, the parameter for the acoustic information that acquisition module receives is the acoustic segment received
Number, the tone of sound and in the duration at least one of, comparison condition is preset with specific tone and specific number of segment
Acoustic segment combination.For example, acquisition module receives three sections of sound, the tone difference of every section of sound when user reads " 1-2-3 "
It is the tone of the pronunciation of number 1,2,3, if identical as comparison condition, output module makes corresponding movement.
Since normal person's sounding word speed is about 3-5 word each second, and the optical signal since user's eye view acquisition to
The surplus for needing a reaction time is made a sound, voice command is set as 3 sections of sound in the above example, and user was at 2 seconds
Acquisition time in complete information input be that there is no problem.It can be to should be able to detect as long as single-chip microcontroller sampling interval duration is reached
Several KHz of the frequency band of audio, acquisition module is fully able to normally in the combination input of above-mentioned low minor, high minor, high long
Ground captures the sound instruction information of user's input, and general normal human's sound is 0-6KHz frequency band, and single-chip microcontroller working frequency is only
About 10-30MHz is needed, and low loud sonority (i.e. the sound intensity) passes through the voltage and current after audio amplification or power amplifier or conversion
To carry out, feature is corresponding to be extracted information after parameter operation.
The setup parameter closed in this present embodiment continues acoustic segment for time parameter, such as in the above example
Time threshold is set as 0.4 second.For loudness parameter, the height power of sound is influenced by the environment including cross-ventilation,
It is related also at a distance from user and sound control output device device, it is therefore desirable to consider the two factors to the shadow of loudness parameter
It rings.The present invention provides the cue modules for user's reference, and design the safe clearance to environment average Voice source, can solve
Certainly above-mentioned two problems.It can such as design and be lower than 20db or be lower than 25db, and is normal higher than the current environment of 90db or 80db
It is not identified with single-chip microcontroller outside range of sounds and does not make any reaction yet.Presetting loudness threshold range in the present embodiment is 20-
90db, i.e., when default loudness threshold is 45db, then 20-45db is bass, and 46-90db is high pitch.It can also according to use environment
Loudness threshold is set as 40db, then 20-40db is bass, and 41-90db is high pitch, to adapt to the ring relatively high in natural noise
Situation in border, enables response lag increase or decrease.
Easy to remember for simplicity, the comparison condition in the present embodiment is set as the sound instruction of " low short-high short-high long ", but
Comparison condition may be set to be the sound instruction of other forms, such as " low short-low short-low length " sound instruction, work normally
In the case of, due to the display of acquisition time range, the correct selection of time parameter and loudness parameter, in addition meeting comparison condition
It is required that since the input of extraneous natural sound or user with other people carry out normal voice and exchange to cause sound control output device
The probability of malfunction mistake output is very small, in order to improve the operation success rate of sound control output device, can also will compare
The sound number of segment of condition, the duration, loudness setting combination settings it is more more complicated, may further ensure that reach in this way
100% operation success rate.
Embodiment two
Sound control output device is applied to driving circuit control lamps and lanterns adjusting brightness and switch in the present embodiment.
Acquisition time is set as 2.5 seconds, acquires the indicator light of beginning as green, which is 0.2
Second.After user sees green indicator light flashing, user issues the sound instruction of " low short-high short-high short-high long ", i.e., first
One section of duration short bass is issued, the duration, volume was that it is defeated to be used to indicate user at this time less than 42db less than 0.3 second
The yellow indicator lamp for entering acoustic segment is bright, and then, user issues two sections of duration short high pitch, and every section of duration is less than 0.3
Second, volume is bright for the red indicating light for greater than 42db, being used to indicate user's input acoustic segment at this time, if sound red indicating light
It is bright, prompt user to improve loudness or close control lamps and lanterns, finally, user issues one section of duration long high pitch, when continuing
Between be greater than 0.3 second, volume be greater than 42db.Above-mentioned indicator light belongs to cue module, and cue module control output optical signal refers to
Show that user audibles instruction input sound control output device, acquisition module acquires the sound instruction of user's input.
Then, the parameter for the acoustic information that comparison module receives acquisition module item compared with being stored in memory module
Part is compared.Specifically, acoustic information parameter is sound number of segment, sound segment length, sound intensity here, and comparison condition connects
Whether the acoustic information received is one section of low minor, two sections of high minors, one section of high long.Wherein, the judgement of bass and high pitch can
It is determined with preset threshold value, such as it is bass that volume, which is less than 42db, it is high pitch that volume, which is greater than 42db,；The judgement of minor and long
It can be determined with preset threshold value, such as the duration was minor less than 0.3 second, the duration is greater than 0.3 second for long.
Finally, when comparison module comparison result is that collected sound is consistent with comparison condition at least once, then
Impulse level signal needed for being matched according to the impulse level signal output of current output unit output according to preset requirement, controls lamp
The operation of tool switch or brightness regulation.For example, if the corresponding impulse level closed of current monolithic machine output, output is become pair
The impulse level that 10% brightness should be exported, entering LED control chip from closed state keeps LED driving output control electric 10%
The open state (LED constant current is controlled by PWM) of stream, lamps and lanterns become 10% glimmer state.If the output of current monolithic machine corresponds to
The impulse level of 10% brightness is exported, then output is become to the impulse level of 100% brightness of corresponding output, LED is made to control chip
Enter fully open state, lamps and lanterns all light from 10% current status.If the output of current monolithic machine fully opens all light impulse level,
Lamps and lanterns are closed, then being just repeated once by above sound combined command, then output are become exporting the pulse of corresponding closing
Level makes LED control chip enter completely closed state from 100% current status, so that lamps and lanterns be made to close.
Embodiment three
Sound control output device is applied to driving circuit control lamps and lanterns Push And Release in the present embodiment.
Acquisition time is set as 1.5 seconds, acquires the indicator light of beginning as green, which is 0.2
Second.After user sees green indicator light flashing, user issues the sound instruction of " one high long ", i.e., when issuing one section first and continuing
Between short high pitch, the duration about 1 second, volume was to be used to indicate the red instruction that user inputs acoustic segment at this time greater than 50db
Lamp is bright for about 1 second, if the red indicating light for being used to indicate user's input acoustic segment at this time does not work, user is prompted to improve sound
Degree.
It is noted that the red indicating light of input acoustic segment, other embodiments can also do not had in the present embodiment
Equally.
Above-mentioned indicator light belongs to cue module, and cue module control output optical signal instruction user audibles instruction defeated
Enter sound control output device, acquisition module acquires the sound instruction of user's input.Then, comparison module receives acquisition module
To acoustic information parameter and memory module in the comparison condition that stores be compared.Specifically, because claim is to limit
At least one sound number of segment, acoustic segment duration, sound intensity, thus the present embodiment be a high long sound instruction herein
It limits in range.
Finally, then basis is worked as when comparison module comparison result is that collected sound is at least consistent with comparison condition
The impulse level signal of preceding output unit output is to close, and exports the impulse level signal of unlatching, and control lamps and lanterns open work,
Then, lamps and lanterns are made to close then above-metioned instruction repeated as above in normal work in lamps and lanterns or other devices, so that lamps and lanterns be made to close
It closes.
Example IV
The present embodiment and embodiment one, two, three the difference is that, comparison condition increases current time condition, output
Different variations is made accordingly.For example, setting daily 23 when next day 7 as sleep period, other periods are the daily life time
Section.In sleep period, comparison condition is the sound instruction of " low short-low short-low short-low short-low short ", and works as comparison condition
When meeting, single-chip microcontroller exports respective pulses level, and LED control chip is made to enter 20% current status, 20% electric current of lamps and lanterns glimmer
State.Within the daily life period, comparison condition is the sound instruction of " low short-high short-high long ", and when comparison condition meets,
Single-chip microcontroller exports high level, and LED control chip is made to enter fully open state, lamps and lanterns all light.
Obviously, because late into the night environment external interference sound is relatively weak, if there is occurring loudly, easily it is noisy to other people, so
The setting of hommization is only to need relatively low sound that can reach control purpose, when user's eye view arrives the head of a bed or indoor lamp
1-2-3-4-5 in a low voice is issued when upper green light flashes and need to be terminated before green light next time flashes, or when eye view is flashed to green light
When issue in a low voice A-B-C-D-E and need to green light next time flash before terminate.
It can be seen that compared with prior art in conjunction with the above detailed description of the present invention, the present invention at least has following
Beneficial technical effect:
First, according to the optical signal information of prefixed time interval timing output predetermined time period, user is guided to acquire
Voice combination instruction is inputted in time range as required, reduces the identification capacity and digit of single-chip microcontroller, reduces operation information
Amount reduces production cost to reduce the operation and response speed requirement to information processing.
Second, based on the setting of unit time, there are also three sound number of segment, sound segment length, sound intensity parameter settings
Comparison condition improves the anti-interference ability to outside noise, reduces since unexpected sound causes error action of device work to occur
Probability, generate circuit and multi-level output while reaching anti-interference and anti-malfunction effect.
Third is provided according to different judging results and the design scheme for combining other factors to carry out different operation, Neng Goushi
Answer relatively broad application scenarios.
In addition, the reason of present invention has the advantage that compared to the prior art essentially consists in:
First, anti-interference and anti-mistake can be reached by the input (including number sequence permutation and combination) of a low high length sound
The function of movement, because other people and natural sound reach the probability of the operation condition of preparatory match settings extremely under normal circumstances
It is small.
Second, setting unit time prompting, i.e., the continuous iterative cycles operation of process of acquisition and output above-mentioned acquires mould
Block is using the unit time as period continuous service.The information operation number to active voice can be reduced after setting unit time prompting
Amount, and the rate request for requiring high speed to timely respond in active voice control is significantly reduced, so that manufacturing cost is reduced, and
Anti-interference and anti-malfunction performance can be improved simultaneously.Such as existing voice control technology require to turn on light voice issue after must be high
Speed matching acoustic information, and it is minimum to detect the time, detecting frequency are generally required up to 200 MHz grades or more, it is desirable that are timely responded to, together
If when other people or natural sound invade simultaneously and also will cause and can not differentiate, it is right and because the time postpones significantly after the setting of unit time
Detecting speed significantly reduces, and response action is to terminate in a unit time, and to meet at least because matching operation condition
Sufficient principle, so enhancing anti-malfunction performance.
Third, setting are currently running the memory module of state, and memory module can recorde the state of current output signal, fill
