Embodiment:
The audio query message file comprises a file label, and a described file label is comprised of a filename and an information bit, and described information bit is used for comparing with response result, judge response result to mistake.
Make in advance the audio query message file, and be stored in the memory module.The content of each audio query message file can be simple mathematical operation, also can be logical operation, or a bit of entertaining story, and the form with "Yes" or " non-" proposes a simple question to the driver at last, and requires the driver to reply.The label of each section audio inquiry message file is comprised of unique filename and information bit, wherein the value of information bit is numeral " 1 " or " 0 ", the correct option of information bit " 1 " or " 0 " corresponding this document " to "/" mistake ", identify and call for microcontroller.
Audio content such as the audio query message file be " 1+1=2, is that right? ", then the information bit that comprises of its file label is " 1 "; Audio content such as the audio query message file be " 2＞3, is that right? ", then the information bit that comprises of its file label is " 0 ".The audio query signal is sent to loudspeaker by audio-frequency module, and loudspeaker sends corresponding audio query information, and audio query information is delivered to driver's ear.Microcontroller is sent value " 1 " or " 0 " of correct option information bit contained in the file label into the judgement comparer.
The pre-anti-drowsy earphone of formula is answered in described inquiry to be worn on ear, start the early warning prompting function of earphone, after inquiry timing T0 finishes, microcontroller is transferred an audio query message file at random from storer, convert the audio query signal to and send by audio-frequency module, be delivered to driver's ear through loudspeaker, simultaneously with the information bit of file label, be sent to the input end of judgement comparer with the form of numeral " 1 " or " 0 ".
The inquiry regularly length of T0 has determined that the driver accepts the frequency of clear-headed inquiry.When driving a conveyance, generally should set inquiry timing T0 and be no more than one minute, namely the driver must accept once or above clear-headed inquiry at least within one minute cycle, so that the driver keeps clear-headed.
The audio query information that requirement is replied is sent, and microcontroller sends replys prompt tone, starts timing, and gathers the output voltage signal of 3-axis acceleration sensor, and reception is replied.
After the driver hears audio query information, through simply thinking, reply in the mode of nodding/shaking the head.The mode that definition is replied is "Yes" or " non-" two kinds of forms, is expressed as "Yes" when the driver nods, and is expressed as " non-" when the driver shakes the head, and meets the people to being the expression custom of non-judgement.
When the content of audio query information be " 1+1=2; is that right? ", the driver nods when replying, and then microcontroller receives 3-axis acceleration sensor at the output voltage signal of Z-direction, namely characterize replying of "Yes", and the numeral " 1 " of corresponding "Yes" is sent into the judgement comparer.Judge that comparer compares the value " 1 " of correct option information bit contained in the audio query message file label with the numeral " 1 " that receives, comparative result equates, then judges and replys correctly, and the driver is in waking state.Shake the head when replying such as the driver, digital " 0 " is sent into the judgement comparer, judge that comparer compares the value " 1 " of correct option information bit contained in the audio query message file label with the digital " 0 " that receives, comparative result is unequal, then judge and reply mistake, judge that the driver is in sleepy state.
When audio query message file content be " 2＞3; is that right? ", the driver shakes the head when replying, and then microcontroller receives 3-axis acceleration sensor at the output voltage signal of X-axis or Y direction, namely characterize replying of " non-", send the judgement comparer with the digital " 0 " of corresponding " non-".Judge that comparer compares correct option information bit " 0 " contained in the audio query message file label and digital " 0 ", comparative result equates, then judges and replys correctly, and the driver is in waking state.When the driver nods when replying, the numeral " 1 " of corresponding "Yes" is sent into the judgement comparer, judge that comparer compares correct option information bit " 0 " contained in the audio query message file label and numeral " 1 ", comparative result equates, judge and reply mistake, the driver is in sleepy state.The Main Function of threshold X, threshold value Y, threshold value Z is the interference of driving in the occasion use in order to eliminate, and is the correlative value that sets in advance.
" 1 " that microcontroller will receive or " 0 " answer signal are sent to the input end of judging comparer, and correct option " 1 " or " 0 " that the audio query information bit of delivering in advance with another input end comprises compare.
When both were equal, microcontroller judged that the driver is in waking state, restarts to inquire cycle T 0 timing.
When both were unequal, microcontroller judged that the driver is in doze state, sends the prompting message of audio frequency and/or vibration mode, and restarts to inquire cycle T 0 timing.
Time threshold T1 differentiates to reply the fiducial value that whether is in effective time, generally is set as 1～3 second, can adjust by the key device input.When the driver is in waking state, after hearing clear-headed inquiry, can within 1～3 second time, effectively thinks deeply, and reply by the mode of nodding or shake the head.
When in time threshold T1, microcontroller is not received arbitrary reply of 3-axis acceleration sensor on X-axis, Y-axis or Z-direction, judges that namely the driver is in doze state.
When microcontroller judges that the driver enters doze state, microcontroller sends the vibrating alert signal to Vib., and Vib. is implemented lasting vibration, by people's cheek and contacting of earphone, seismesthesia is delivered to human brain, and the prompting driver recovers waking state as early as possible.Send the audio alert signal by audio-frequency module to loudspeaker simultaneously, loudspeaker is sounded, and it is clear-headed that reminding driver recovers, and do suitable rest.After reminding driver was done suitable rest, 0 timing of inquiry cycle T began.
After judging that comparer judges that continuous unequal number of times accumulative total reaches threshold value 2, microcontroller sends the vibration alarming signal to Vib., and send audio alarming signal by radio receiving transmitting module to audio-frequency module, Vib. is implemented strong vibration, loudspeaker sends chimes of doom simultaneously, microcontroller also sends danger alarm signal by radio receiving transmitting module to Surveillance center, or by console the vehicles is taked the urgent danger prevention measure.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
