Abstract
The utility model discloses a review mirror that prevents sleeping during driving, including a review mirror, characterized in that an anti-sleeping device is positioned on the review mirror. Such anti-sleeping device consists of an image sensor, a control device and an alarm device. The image sensor collects facial information of the drive to send to the control device which will then analyze the information to determine whether to start the alarm device according to analysis results. The alarm device can give out light, sound and electronic signals. The utility model has the advantages in that the device fully takes advantage of the characters and functions of the review mirror and has the anti-sleeping device installed on the review mirror, thus, endowing the review mirror with uncommon functions that ordinary ones do not have to prevent sleep, which is convenient and powerful in terms of anti-sleeping with a high level of accuracy.
Description
One, technical field
The utility model relates to a kind of automobile rearview mirror, particularly a kind of automobile rearview mirror that prevents the driver drowsy device that has.
Two, background technology
Fatigue driving causes to knock easily sleeps, and dozes off to make the decreased attention of chaufeur, is the major reason that causes express highway to get on the car to have an accident.Studies show that only in one hour, the sign of decreased attention will appear in chaufeur in continuous driving on the expressway.In order to reduce the phenomenon of this serious threat traffic safety as far as possible, Drowse-proof device is all driven in research by research institution both at home and abroad.Domestic existing anti-SLEEPING ALARM UNIT, it is a kind of device that utilizes the work of electronic equilibrium principle that is worn on the chaufeur ear, when chaufeur may produce sleepiness in the driving way, when head turned forward, this device just can give the alarm, and this Drowse-proof device need be worn on ear, both inconvenient, can not forecast other situations in advance, wrong report is many, and practicality is lower.Japan Toyota Company adopts the mode of contact to handle, and promptly adorns a kind of pulse and temperature sensor on vehicle steering, judges that by detecting chaufeur beat pulse frequency and variation of temperature whether chaufeur has tired sign, sends warning again.The extraneous circumstance influence is very big because environment inside car complexity, chaufeur are originally experienced, and can not reflect truth under a lot of situations of the variation of its heartbeat, and this mode erroneous judgement may occur or not declare, so the sign of also not putting on market.Also there is a kind of variation to judge whether it is fatigue driving by the chaufeur facial expression, the anti-device of sleeping of knocking that gives the alarm then, but because the position of installing is inappropriate, thereby poor effect.
Three, summary of the invention
1, goal of the invention: the purpose of this utility model is in order to overcome the deficiencies in the prior art, provide a kind of Drowse-proof device is installed in the anti-automobile rearview mirror of sleeping of knocking on the automobile rearview mirror, it can monitor the facial expression of chaufeur, the state of eyes particularly, judge whether chaufeur has sleepy sign, and prompting is reported to the police.
2, technical scheme: for achieving the above object, a kind of anti-automobile rearview mirror of sleeping of knocking described in the utility model, it comprises the automobile rearview mirror that is installed in the automobile, it is characterized in that, on this back mirror Drowse-proof device is installed.
Described Drowse-proof device is installed in the active situation of the facial expression, particularly eyes that can monitor the monitoring chaufeur on the back mirror of automotive interior, installs simple and convenient.Because chaufeur mixes up the situation of the back mirror of oneself with correct observation automobile back always, Drowse-proof device always can be aimed at the face of chaufeur like this, so this device is fit to the chaufeur that height differs.
3, beneficial effect: this uses later-model advantage is characteristics and the function that makes full use of automobile rearview mirror, to prevent knocking the device of sleeping is installed on the automobile rearview mirror, thereby make automobile rearview mirror, the effect that not only has general automobile rearview mirror, and have anti-sleepy function concurrently, easy to use, prophylactic function is strong, and the accuracy rate height.
Four, description of drawings
Fig. 1, Fig. 2 are structural representations of the present utility model.
Five, the specific embodiment
The utility model design-calculated is anti-knocks the automobile rearview mirror of sleeping and comprises back mirror 1 and anti-ly knock the device 2 of sleeping, and back mirror 1 is installed in the front upper place that is positioned at operator's compartment in the automobile, anti-ly knocks minute surface one side that the device 2 of sleeping is installed in back mirror 2.
Above-mentioned Drowse-proof device 2 can be the various existing anti-devices of sleeping of knocking, and the utility model provides a kind of as an embodiment to be prevented knocking the device of sleeping, and this device comprises image sensor, control setup and warning device.Image sensor obtains the expression action message of chaufeur, and is transferred to control setup, and control setup carries out analyzing and processing to this information, and according to analysis result decision whether startup warning device.Warning device can send information warnings such as sound, light, electricity.
In order to make image sensor obtain information accurately, some infrared invisible light emitting sources can be set on automobile rearview mirror, making the image sensor to infrared-sensitive still is the facial expression that can both photograph chaufeur daytime regardless of night.
The front of image sensor also has infrared cover, is used for filtering other visible lights, make daytime with night effect the same substantially, and reduce the interference of other light.
As shown in Figure 1, Drowse-proof device 2 comprises image sensor 21, infrared transmitting tube 24, control setup, Warning light 23 and buzzer phone, image sensor 21 obtains the expression action picture of chaufeur, and be transferred to control setup, the picture that control setup is sent image sensor 21 is analyzed, and according to analysis result decision whether startup Warning light 23.
As shown in Figure 2, image sensor 21 and warning device 23 are installed in minute surface one side of back mirror, and control setup is installed in the back side of image sensor and light deflector.Be provided with 6 infrared transmitting tubes 24 around the image sensor 21.Be provided with at image sensor 21 with above the infrared transmitting tube 24 can only the transmission near infrared light near infrared light shield 25.
Special version: control setup and in the back of the eyeglass and the optical lens of light deflector, buzzer phone is installed in the behind of control setup, does not all have to section out on figure.
