Abstract
This invention relates to an alarm for testing fatigue of drivers composed of a glass with a reflection fiber shift sensor and an intelligent control system, which takes the expression of fatigue of the eye part as the primary standard to set up a math model to monitor the flash frequency of eyelid, the close time, running of eye balls and pupil contraction and expansion so as to emit acousto-optical warning or force it stopping.
Description
Technical field:
The present invention relates to a kind of driver fatigue detection alarm device, belong to traffic safety protection warning utensil.This device has fatigue driving is sent acousto-optic warning and forced parking function.
Background technology:
Multiple driver fatigue alarm is arranged in the market, brought into play great role for reducing traffic hazard.But,, and make existing driver fatigue alarm be difficult to popularization in phenomenons such as report, fail to report, misrepresent deliberately often appear in actual application because existing unreasonable products structure, technology are immature.Therefore the present invention discloses a kind of driver fatigue detection alarm device, to meet the need of market.
Summary of the invention:
For overcoming the deficiency that prior art exists, the present invention discloses a kind of driver fatigue detection alarm device, and this device is made up of Fibre Optical Sensor and intelligence control system.According to people's fatigue, at first be the fatigue of brain, its presentation be the people in the moment out of trim, body or rock with laughter, or vacillate now to the left, now to the right, women's head-ornaments portion attitude is not normal or kowtow suddenly, the drowsiness of dozing off, or catacleisis stops dodging, and looks mechanism such as thing is unconcerned to be stuck with paste, and the power of handling seperately is blunt.Utilization Fibre Optical Sensor comparative advantages; Simple in structure, volume is little, the highly sensitive millimeter level displacement measurement that is suitable for, and good insulating, anti-interference, light path is flexible, is convenient to realize the characteristics of noncontact monitoring, designs driver fatigue detection alarm device of the present invention.Determine that the expression with eye fatigue is a benchmark, set up mathematical model, eyelid is flashed frequency, closure time and even eyeball rotate, pupil is received to expand and carried out dynamic monitoring, can in time and exactly send acousto-optic warning or force fatigue driving and stop.Said sensor is two reflective optical fiber displacement sensors, is assembled on the both sides frame of one pair of glasses, and the probe that makes Fibre Optical Sensor is over against eyelid, and is connected with the intelligent control system device associated socket with optical fiber, so that transmission information.And intelligent control system device is in a cabinet that is provided with display lamp, high pitch loud-speaker, orderly being installed with assembles with electronic devices and components: photoelectric commutator, amplifier, A/D transducer, single-chip microcomputer, topworks-comprise acousto-optic warning, light control, forced braking system, and with the car car of using this device on relevant power supply, light, brake system, be connected by socket.Use the cabinet of intelligent control system device adhesive above the instrument platform of car then, earlier the glasses that Fibre Optical Sensor is housed are put on during steered vehicle, as long as car starts the also operation simultaneously of fatigue detecting warning device.Warning device will be warned three times loudly with " you are tired; hasten to have a rest " in the time of the stroboscopic red light when driver fatigue, both can remind driver's driving of taking care, and also will cause other rider's vigilance, urge the driver to have a rest, to avoid taking place traffic hazard.If the driver refuses to advise and acts rashly, forced braking system will in time play a role, and send the light emergency brake simultaneously that is about to parking.Green-yellow light is alternately glittering if the driver is in the best of spirit.
The reflective optical fiber displacement sensor that driver fatigue detection alarm device of the present invention is selected and traditional its beneficial effect of sensor comparison are:
1. simple in structure, the measuring accuracy height is suitable for millimetre-sized non-contact displacement measurement;
2. electrical insulating property is fabulous, and strong interference immunity disturbs comprising anti-electromagnetic field interference, anti-radio wave interference and anti-nuclear electromagnetic pulse;
Volume little, from heavy and light, be convenient to be assembled on the glasses, realize eyelid, eyeball fine motion are detected;
4. reflection-type optical fibre sensor is by Optical Fiber Transmission information, and loss is little, error is low, is suitable for remote measurement, is convenient to realize that sensor and intelligent control system device are discrete.
Description of drawings:
Fig. 1. reflective optical fiber displacement sensor and glasses assembling synoptic diagram.Sequence number (1) reflective optical fiber displacement sensor, the both sides same position is respectively assembled one, (2) glasses, (3) optical fiber, (4) plug.
Fig. 2. the cabinet schematic appearance of intelligent control system device.The cabinet of sequence number (5) intelligent control system device, (6) high pitch loud-speaker, (7) fiber-optical socket, (8) with car on relevant power supply, light, brake system gang socket, (9) power switch, (10) loud-speaker amount of sound is regulated turn-knob, (11) eye dynamic LED display lamp, red, yellow, green three looks.
Embodiment:
At first Fibre Optical Sensor (1) is assembled on the both sides frame of spectacle-frame, it is stand-by to make optical fiber (3) in order.Again the cabinet of intelligent control system device (5) is fixed on the instrument platform of car, the fibre circuit of energized and mail message, the Optical fiber plug on the glasses (4), insert fiber-optical socket (7) lining, the driver puts on one's glasses and carries out energizing test then, if yellowish green lamp is alternately glittering, the illustrative system operation is normal, if close order for up to 1 second, red light is with stroboscopic, the high pitch loud-speaker spread out of " you are tired, hasten to have a rest! " caution sound, surpass and then can force for 1 second to stop if close the order time.Prove that so then driver fatigue detection alarm meets designing requirement of the present invention
Claims (3)
1. driver fatigue detection alarm device, this device is made up of Fibre Optical Sensor and intelligence control system, it is characterized in that: said Fibre Optical Sensor is reflective optical fiber displacement sensor (1), it is assembled on one pair of glasses both sides frame, the probe that makes sensor is over against eyelid, and by optical fiber (3) sensor and intelligence control system coupled together; And intelligent control system device, it is cabinet (5) lining that is provided with display lamp, high pitch loud-speaker at, orderly photoelectric commutator, amplifier, A/D transducer, single-chip microcomputer, the topworks of being installed with, comprising acousto-optic warning, forced braking system, and with the car car of using this device on relevant power supply, light, brake system be connected by socket (8).
2. driver fatigue detection alarm device according to claim 1, is characterized in that: the said glasses that are assembled with reflective optical fiber displacement sensor, be worn over probe that women's head-ornaments portion makes sensor over against eyelid, and it is carried out contactless detection of dynamic.
3. driver fatigue detection alarm device, according to claim 1, it is characterized in that: said acousto-optic warning is when driver fatigue, warning device will be cried out " you are tired, hasten to have a rest " loudly from the high pitch loud-speaker in the stroboscopic red light! Warn three times, act rashly if the driver refuses to advise, forced braking system will in time play a role, and send the light emergency brake simultaneously that is about to parking, if the driver is in the best of spirit, then green-yellow light is alternately glittering.
