Abstract
The invention discloses an automobile driver fatigue driving recognition system which comprises a main controller and an image collection module, a voice alarming module and an automobile braking module which are all connected with the main controller. The image collection module comprises a camera, an analog/digital (A/D) converter and a digital signal processor (DSP) which are sequentially connected. The DSP is connected with the main controller. The automobile braking module comprises a speed sensor, an automobile state module and a relay which are sequentially connected, and the speed sensor and the relay are both connected with the main controller. The voice alarming module comprises a voice prompter and an alarm which are connected, and the voice prompter is connected with the main controller. The camera shoots the facial expression of a driver, data obtained through the shooting are converted through the A/D converter to be transmitted to the DSP which processes and computes an image to judge whether the driver is in the fatigue state and judge the fatigue level, a result is input into the main controller, and the main controller sends out a corresponding instruction according to the data processed by the DSP.
Description
Technical field
The present invention relates to a kind of field of security identification of automobile driver, the recognition system field that particularly a kind of fatigue of automobile driver is driven.
Background technology
The research of driving fatigue is divided into two kinds of methods of subjectivity and objectivity, and subjective research technique has that subjective bar is tabled look-up, chaufeur oneself record, sleep habit questionnaire Stamford sleep yardstick table four kind.The method of measurement such as body temperature when objectively method has electroencephalogram (examining electrode used therein), electroculogram, electromyogram, respiratory air flow (twang sensor), effect of breathing (thoracic cavity portion sensor), arterial blood oxygen saturation (finger probes) (obtaining with infrared ray ear probe) and cardiogram while sleeping (driving and).Although these methods are more accurately, because these methods are generally to measure before driving or after driving, be leading or hysteresis, be non real-time.Moreover it is also very difficult in the limited space of operator's compartment, settling complicated detector.And the state of mind that chaufeur departs from operator's compartment or do not enter operator's compartment is different, more accurate its result of a measurement of instrument also can be subject to very large impact.
Summary of the invention
For overcoming the above problems, the invention discloses the recognition system that a kind of fatigue of automobile driver is driven, reduce the generation of traffic accident.
The present invention adopts following technical scheme:
The recognition system that a kind of fatigue of automobile driver is driven, comprise master controller, the image capture module being all connected with master controller, audio alert module and automobile brake module, described image capture module comprises the pick up camera connecting successively, A/D converter and dsp processor, dsp processor is connected with master controller, described automobile brake module comprises the speed sensor connecting successively, vehicle-state module and relay, speed sensor is all connected with master controller with relay, described audio alert module comprises the voice message and the annunciator that are connected, voice message is connected with master controller.
Described pick up camera is taken the facial expression of chaufeur, by the data that obtain after taking after the conversion of A/D converter, send into dsp processor, dsp processor is processed image and computing, whether judge chaufeur in fatigue state and tired grade, and result is inputted to master controller, master controller is processed data later by dsp processor and is sent corresponding instruction.
Described speed sensor is for implementing to monitor the motoring condition of current automobile, described relay is the electromagnetic relay of connecting on the circuit between ignition lock and primary ignition coil, and open close by the external aerotron control relay of master controller, and by the open and close controlling firing circuit of described relay contact, when detect warning start after after certain time, chaufeur is still in the time of fatigue state, and master controller makes to force automobile to stop by controller relay.
Described audio alert module has mainly entered the state of fatigue driving by annunciator prompting chaufeur, and described annunciator is that buzzer phone adopts speech chip, Embedded preposition, the amplifier of crystal oscillator, Mike and automatic gain control.
The present invention compared with prior art has the following advantages: adopt pick up camera to take the facial expression of chaufeur, then pass through computing and the processing of dsp processor, realizing phonetic alarm in the time that chaufeur enters fatigue state reminds chaufeur to enter fatigue state, suggestion is had a rest, when after phonetic alarm has been reported to the police certain time, chaufeur is still in fatigue state, master controller force disconnect oil circuit, force automobile stop motion, in case major structure becomes traffic accident, the fatigue state that adopts pick up camera to implement monitoring chaufeur can remind chaufeur to enter fatigue state, to reduce the generation of traffic accident.
