Fig. 2 is microphone and signal amplification circuit figure.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
With the acoustic control electric fan is example:
As shown in Figure 1, comprise microphone, reservoir, single-chip microcomputer, acoustic control amplifying circuit and pilot lamp; Single-chip microcomputer is connected with acoustic control amplifying circuit, reservoir, pilot lamp and Be Controlled electrical equipment (like the acoustic control electric fan) respectively, and the acoustic control amplifying circuit is connected with microphone again.
As shown in Figure 2, described single-chip microcomputer is the ATmega16L-8PI single-chip microcomputer, and reservoir is the AT24C02 reservoir, is a 2K bit serial CMOS E2PROM, and 256 octets are contained in inside, and this reservoir is operated through the iic bus interface; The acoustic control amplifying circuit is the circuit that has MSMAS42Z type silicon microphone and lm358 amplifier chip; The PB3/AI1/OC0 pin of said single-chip microcomputer is connected with said acoustic control amplification circuit output end mouth, and the SDA/PC1 of said single-chip microcomputer links to each other with SDA, the SCL pin of reservoir with the SCL/PC0 pin.The acoustic control electric fan links to each other with the PD5/OC1A interface of single-chip microcomputer.
Microphone links to each other with single-chip microcomputer through the acoustic control amplifying circuit, can gather acoustic impluse; Storage module can be stored the prerecording instruction; Pilot lamp helps indicating operating status.The SCM Based anti-interference acoustic control device of pre-recording can continue to wait for user instruction after receiving voice signal and the anti-interference signal comparison of pre-recording, being identified, and fan is done further various control.
The acoustic impluse signal of microphone collection inserts relatively input end of single-chip microcomputer with the acoustic impluse signal that has amplified after the acoustic control amplifying circuit is amplified to suitable multiple.When the applied signal voltage value was higher than predefined benchmark comparative voltage, single-chip microcomputer was judged and is captured this acoustic impluse signal.
The user can prerecord open command and deposit storage module in.When the acoustic control device is in when prerecording pattern, user arbitrarily three of typings is no more than 1500 milliseconds acoustic impluse apart from one another by the time.Single-chip microcomputer extracts respectively between first and second acoustic impluse, the time interval (resolution is 10 milliseconds) between second and the 3rd acoustic impluse, deposits it in AT24C02 reservoir.Afterwards, pilot lamp lights the prompting completion to pre-recording into the sampling and the storage of instruction.During power down, the information in the AT24C02 reservoir can not lost.After the single chip circuit energising, read pre-recording in the AT24C02 reservoir, get into holding state and prepare the identification user instruction into instruction.
When the acoustic control device is in recognition mode, will after receiving first acoustic impluse signal, pick up counting, wait for second acoustic impluse signal.If receive second acoustic impluse signal and between first time interval do not wait into the interval of instruction with pre-recording, perhaps the stand-by period surpasses 1500 milliseconds, then single-chip microcomputer is judged as and receives undesired signal, returns the initial conditions of recognition mode.If receive second acoustic impluse signal with first between the time interval equate with the interval of pre-recording into instruction, then wait for the 3rd acoustic impluse signal.
In like manner, all when pre-recording into sound pulsion phase etc., the instruction that the user sends could be passed through identification two time intervals that and if only if between three acoustic impluses.Pilot lamp lights afterwards, prompting user acoustic control device identification user success.After recognizing the acoustic impluse instruction, then read the acoustic impluse number of times in 4 seconds subsequently." 0 time " then makes electric fan begin to rotate; " 1 time " makes fan begin to rotate and be automatically made first grade of rotating speed; " 2 times " make electric fan begin to rotate and be automatically made second grade of rotating speed.
If electric fan is in running status, the acoustic control device recognizes acoustic impluse, then reads the acoustic impluse number of times in 4 seconds subsequently." 0 time " stops operating fan, transfers holding state to; " 1 time " is automatically converted to first grade of rotating speed; " 2 times " are automatically converted to second grade of rotating speed.
Discern successfully, after warning light lights, the acoustic control device can be counted the acoustic impluse number that reads in 4 seconds next.The user can clap the hands in 4 seconds for several times thus, accomplishes sending the further steering order of electrical equipment.The different audio pulse number is (as 0 time, 1 time, 2 times ...), corresponding Different control instruction.After steering order was sent, the acoustic control device transferred the initial conditions of recognition mode to, waited for identification next time.
It is pointed out that the said acoustic impluse that receives at interval with pre-record when comparing into the sound recurrent interval because that the recurrent interval is difficult to is equal fully, the people feels also inaccurate to time rhythm.For reducing the User Recognition difficulty, pre-record into time interval number respectively add and deduct an error time, become between cog region.The time interval that receives is effectively in dropping between this cog region.Experiment shows, if the time interval less than 500 milliseconds, then error is desirable 60 milliseconds; If interval greater than 500 milliseconds, then error is desirable 100 milliseconds.Can guarantee accurate identification this moment, can not use the user again and cause difficulty.
