Abstract
The invention discloses an anti-high beam structure for an automotive windscreen and a control method for the anti-high beam structure. The anti-high beam structure comprises a control chip, a transparent liquid crystal screen and four cameras, wherein the transparent liquid crystal screen has the same shape with the windscreen, and is attached to the windscreen, and the control chip is electrically connected with the transparent liquid crystal screen; sensors are arranged on the cameras, and the cameras are arranged in the four corners of the transparent liquid crystal screen. The control method comprises the following steps: S1, pre-storing position information of human eyes in the control chip; S2, acquiring the distances between a light source and the cameras by virtue of the four cameras; S3, calculating position information of an intersection of a straight line formed by the light source and the human eyes and the transparent liquid crystal screen. According to the structure, the position of the light source is determined through the cameras, then the position, where the light source is directly incident into the eyes of a driver, of the display screen is determined, and after the position is determined by the control chip, a black spot is displayed at the position to cover most of light directly incident into the eyes, so that the effect of safe driving is achieved.
Description
Technical field
The present invention relates to auto parts and components field, particularly relate to a kind of anti-high beam structure of windshield and control method thereof.
Background technology
At present; automobile is very general, lives with people, inseparable; but the driving safety of automobile really has a strong impact on the life security of people; the eyes travelled, when high beam opened by the automobile in a distant place, are first damaged by especially night running; and due to high light; drivers cannot see front clearly, and vehicle accident often occurs, and even causes life danger.
Summary of the invention
For solving above-mentioned technical problem, the present invention proposes a kind of anti-high beam structure of windshield, including control chip, transparent liquid crystal screen, four photographic head, described transparent liquid crystal screen is identical with the shape of windshield, and it is affixed on described windshield, described control chip and described transparent liquid crystal screen electric connection；Described photographic head is provided with sensor, and is arranged on described transparent liquid crystal screen corner.
Preferably, described sensor is range sensor.
The control method of the anti-high beam structure of a kind of windshield, comprises the following steps:
S1: the positional information of the human eye that prestores in control chip；
S2: four photographic head obtain the light source distance to photographic head；
S3: calculate the positional information obtaining the light source straight line with human eye with the intersection point of transparent display screen；
S4: after obtaining positional information, control chip controls transparent display screen and shows black mottle in point of intersection.
Windshield anti-high beam structure and control method thereof that the present invention proposes have following beneficial effect: this device determines light source position by photographic head, determine the position of display screen of eyes entering driver in corresponding direct projection again, after control chip determines position, at this position display black mottle, most of light that direct projection enters eyes blocks, it is achieved the effect of safe driving.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in the embodiment of the present invention, below the accompanying drawing used required during embodiment is described is briefly described.
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the planar structure schematic diagram of the present invention；
Fig. 3 is the schematic diagram obtaining mottle position；
Wherein, 1-transparent liquid crystal screen, 2-sensor, 3-light source, 4-lens.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
In conjunction with Fig. 1, Fig. 2, Fig. 3, the present invention proposes a kind of anti-high beam structure of windshield, including control chip, 1, four photographic head of transparent liquid crystal screen, described transparent liquid crystal screen 1 is identical with the shape of windshield, and it is affixed on described windshield, described control chip and described transparent liquid crystal screen 1 electric connection；Described photographic head is provided with sensor 2, and is arranged on described transparent liquid crystal screen 1 four jiaos.
Wherein, four photographic head are for showing the positional information of remote source 3, by positional information storage and chip.
Preferably, described sensor 2 is range sensor 2, is used for detecting positional information.
The control method of the anti-high beam structure of a kind of windshield, comprises the following steps:
S1: the positional information of the human eye that prestores in control chip；
S2: four photographic head obtain the light source 3 distance to photographic head；
S3: calculate the positional information obtaining the light source 3 straight line with human eye with the intersection point of transparent display screen；
S4: after obtaining positional information, control chip controls transparent display screen and shows black mottle in point of intersection, and wherein mottle has certain transparency, effectively prevents from affecting sight line.
The location method determining light source 3 is: such as Fig. 2, when after the lens 4 of the light therethrough photographic head of light source 3, an intersection point can be had on sensor 2, the distance at this range sensor 2 center is known, further according to the distance between photographic head and eyeglass, can drawing an angle [alpha], namely four angles can determine that light source 3 position, again owing to the position of human eye is determined, the line between 2 can show mottle on transparent liquid crystal screen 1.
The multiple amendment of embodiment be will be apparent from for those skilled in the art, and generic principles defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention is not intended to be limited to the embodiments shown herein, and is to fit to the widest scope consistent with principles disclosed herein and features of novelty.
