The utility model discloses the method of utilizing ultrasonic ranging detects driver's head apart from the distance of driver fatigue alarm, determines the driver and whether is in the fatigue state, and then judge and whether administrate driver's alarm, and it is sensitive convenient to use, and the volume is less, and the cost of manufacture is low, and market value is high.
Description
Technical field
This utility model relates to fatigue driving alarm technical field, particularly relates to a kind of ultrasonic ranging type fatigue driving alarm.
Background technology
Along with increasing substantially of China's economic strength and level of medical and health, the mortality rate of population gradually reduces；But, according to the statistics of relevant department, the traffic mortality rate caused due to fatigue driving is but constantly raising, so, how to control and reduce the fatigue of driver to be always traffic safety researchers' focus of attention.
And in present published fatigue driving alarm technology, have plenty of, according to driver, the grip size of steering wheel is judged whether driver is in fatigue state, this method easily allows driver painstaking on hand, and reports by mistake；Have judges fatigue driving according to the eyes dynamic frequency that blinks, and the most not only product cost is high, uneconomical, and accuracy rate of reporting to the police is the lowest, unsuitable large-scale popularization.So invent a kind of simple in construction, the fatigue driving alarm that with low cost, easy to operate, warning accuracy rate is high has become as the urgent needs of society.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
As shown in Figures 1 and 2, this utility model provides a kind of ultrasonic ranging type fatigue driving alarm；Including data acquisition unit, data transmission device, data sink；Data acquisition unit includes device box body 3, is provided with ultrasonic detector 4, single-chip microcomputer 6, buzzer 7, power supply in device box body 3；When ultrasonic detector 4 is used for detecting driver fatigue, the distance of nose drop, and the distance data transmission detected is transferred to buzzer 7 to single-chip microcomputer 6, single-chip microcomputer 6 after the data received being processed；Power supply is electrically connected with ultrasonic detector 4, single-chip microcomputer 6, buzzer 7, provides the power supply needed for work to them.
Data transmission device is wired transmission device or radio transmitting device；Wired transmission device preferred embodiment is earphone cord 2, radio transmitting device can be bluetooth transmission means, infrared transmission means or Wi-Fi transmitting device etc., and the effect of data transmission device is that the data information transfer collected by data acquisition unit is to data sink.
Data sink is cable reception device or radio receiver；Cable reception device preferred embodiment is earphone 1, wireless reception device can be that Bluetooth receptions device, infrared receiving device or Wi-Fi receive device etc., the effect of data sink is to receive data message and play to driver, plays the effect of alerting drivers fatigue driving.
In order to preferably power for fatigue driving alarm, it is preferable that power supply also includes the first power supply 9 and second source 10；First power supply 9 is electrically connected with buzzer 7, provides working power for buzzer 7；Second source 10 is electrically connected with single-chip microcomputer 6 and ultrasonic detector 4, provides working power for single-chip microcomputer 6 and ultrasonic detector 4.In order to prevent, electric current is excessive burns components and parts, is provided with protective resistance 8 between the first power supply 9 and buzzer 7.In order to be preferably fixed on the neck of driver by fatigue driving alarm, being additionally provided with fixing 5 on device box body 3, fatigue driving alarm can be fixed on the collar of driver's clothes by fixing 5.
During use, first pass through earphone cord 2 and earphone 1 is attached with device box body 3, then the fixing 5 on device box body 3 is clipped on the collar of driver's clothes, to receive from the warning message in device box body in earphone 1 is filled in the ear of driver.When driver starts running, ultrasonic detector 4 gathers the distance of driver's chin distance means box body 3 in real time；The range information collected when driver head looks squarely front for a long time is safe distance information, and when driver fatigue, nose drop, the range information that ultrasonic detector 4 collects is shorter than safe distance data and i.e. obtains risk distance information；Now risk distance information is transferred to single-chip microcomputer 6, single-chip microcomputer 6 sends data message to buzzer 7, data message is converted into buzzer warning sound and is transferred to earphone 1 by earphone cord 2 by buzzer 7, buzzer warning sound is transferred to the ear of driver by earphone 1 again, thus make dangerous driving to driver and remind, and then the generation avoided traffic accident.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
