Abstract
The utility model discloses an automatic switching device for distance light and passing light during night driving. The automatic switching device comprises a distance lamp, a passing lamp, an optical splitter, a singlechip, a photosensitive sensor, an ultrasonic radar range instrument and a velocity sensor, wherein the photosensitive sensor, the ultrasonic radar range instrument and the velocity sensor are connected with the singlechip respectively; an output end of the singlechip is connected with the optical splitter; and an exit slit of the optical splitter is connected with the distance lamp and the passing lamp respectively. The automatic switching device adopts a sensor technology, a radar ranging technology and a singlechip technology; automatic switching for the distance light and the passing light of an automobile during the night driving is achieved; a driving accident possibly caused by inappropriate use of the distance lamp at night is avoided effectively; and the night driving safety of a driver is ensured. The automatic switching device is simple in structure, high in reliability, and high in practicability, and is widely applicable to other motor vehicles.
Description
Technical field
The utility model belongs to the automotive safety technical field, particularly a kind of night travel distance-light automatic switching control equipment.
Technical background
According to the relevant data statistics, the traffic accident that night travel is caused by mal use country beam accounts for about three one-tenth of night traffic accident.The light beam position of dazzle light is higher, and is substantially concordant with the sight line of sending a car in front truck or opposite.People's pupil can dwindle in the high light environment, reduces light-inletting quantity with this.Otherwise during from high light to relatively dark environment, people's pupil will enlarge, to increase light-inletting quantity, the situation around can seeing clearly.The convergent-divergent of pupil needs a process, and this has just produced snow-white " the moment blind area " of a slice at the moment.The driver beats country beam in violation of rules and regulations, will allow other driver or cyclist's eyes the moment blind area occur, in this process, very easily causes traffic accident.
Summary of the invention
The purpose of this utility model is, a kind of night travel distance-light automatic switching control equipment is provided, and this device can be realized automobile car light distance light and dipped beam automatic switchover in the night running process, has guaranteed the safety of chaufeur.
In order to realize above-mentioned task, the utility model is solved by the following technical solutions:
A kind of night travel distance-light automatic switching control equipment, comprise country beam, passing light, spectroscope, micro controller system, photosensor, ultrasonic radar range finder and speed sensor, wherein, photosensor, ultrasonic radar range finder and speed sensor connect respectively micro controller system, the mouth of micro controller system connects spectroscope, and the exit slit of spectroscope connects respectively country beam and passing light.
The utility model also has following other technologies characteristics:
Described micro controller system adopts the AT89C2051 micro controller system.
Described photosensor adopts the MOC6002 sensor.
Described ultrasonic radar range finder adopts the BW17-texIII apomecometer.
Described speed sensor adopts the JK08/NS43NCT1 sensor.
The utility model profit sensor technology, radar ranging technology and singlechip technology realize that the distance-light of automobile in the night running process automaticallyes switch.Street lamp is arranged night or the good urban pavement that throws light on take dipped beam as main, and use country beam when travelling night on there is no street lamp or underlit road.The utility model has effectively been avoided the train operation accident that may cause due to improper use country beam night, has guaranteed driver's night travel safety.This apparatus structure is simple, and reliability is high, and is practical, can be widely used in all kinds of self-propelled vehiclees.
Description of drawings
Fig. 1 is structure connection diagram of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
The specific embodiment
Fig. 1 is structure connection diagram of the present utility model, comprise country beam, passing light, spectroscope, micro controller system, photosensor, ultrasonic radar range finder and speed sensor, wherein, photosensor, ultrasonic radar range finder and speed sensor connect respectively micro controller system, the mouth of micro controller system connects spectroscope, and the exit slit of spectroscope connects respectively country beam and passing light.Described micro controller system adopts the AT89C2051 micro controller system, and described photosensor adopts the MOC6002 sensor, and described ultrasonic radar range finder adopts the BW17-texIII apomecometer, and described speed sensor adopts the JK08/NS43NCT1 sensor.
When night travel, photosensor detects the lighting condition of travel, and information is passed to micro controller system.If micro controller system judgement road illumination is all right, controls spectroscope and open passing light, otherwise open country beam.
During nighttime meeting, photosensor can catch the head lamp signal of direction to the car, judges by micro controller system whether opposite direction sends a car, and this moment, the ultrasonic distance measuring radar apomecometer can be measured Ben Che and the distance of sending a car.The speed sensor that is arranged on this car can be known this vehicle speed information, and micro controller system is processed the data message from photosensor, ultrasonic radar range finder and speed sensor, then controls spectroscope and opens distance light etc. or passing light.Control policy is, this vehicle speed during greater than 60km/h, apart from front truck 200m distance light switch to dipped beam; Switch dipped beam during less than 60km/h, apart from front truck 150m at this vehicle speed, after Vehicle during Crossing Event finishes, dipped beam switches back distance light again.
The electronic devices and components that the utility model adopts are known product, and those skilled in the art are according to the i.e. concrete connection mode of electronic devices and components as can be known of the technical solution of the utility model.
Below by reference to the accompanying drawings embodiment of the present utility model is described; but the utility model is not limited to above-mentioned specific embodiments; above-mentioned specific embodiments is only schematic, guiding; rather than restrictive, all equivalents of doing on present techniques scheme basis all fall into protection domain of the present utility model.
