Abstract
The invention provides a device for preventing an automobile rear distant light from dazzling a driver and belongs to the field of electronics. The device can prevent the driver from being disturbed by light of the automobile rear distant light at night and improves running safety and driving comfort.
Description
Technical field
The invention provides and a kind ofly prevent that rear car country beam from dazzling destination device
,belong to person in electronics, this device can help automobile driver in the interference that prevents at dark rear car country beam light, improves the comfort level of traffic safety and driving.
Background technology
During driving at night, car is below opened headlight, and the interference that driver is produced to light, has a strong impact on traffic safety.
Use this device to overcome the above problems well, owing to having used optical pickocff and LCD technology, cost significantly declines.
Summary of the invention
The object of this invention is to provide a kind of based on optical pickocff detection high light, the light transmission of dynamic adjustments LCD, thereby the reflective amount of adjusting rearview mirror, prevent the technology of dazzle, this device is placed on black and white LCD display panel on automotive rear-view light deflector, by crossing automatic photoreceptor, induction high light below, then adjust the Black-White of LCD, light transmission namely, thus can control the catoptrical intensity on light deflector.Hardware of the present invention is comprised of optical pickocff, LCD display panel, lcd controller etc.
Technical scheme of the present invention: comprise optical sensor module, signal processing module, LCD driver module, locking and memory module, the mouth of optical sensor module connects the input end of signal processing module, the mouth of signal processing module connects the input end of LCD driver module, and the mouth of LCD driver module connects the input end of locking and memory module.
The present invention has advantages of: 1. the accurate service condition of medicine.2. with low cost.
Accompanying drawing explanation
Fig. 1 is block diagram of the present invention.
the specific embodiment
As shown in Figure 1, the present invention is a kind of prevents that rear car country beam from dazzling destination device, comprise optical sensor module, signal processing module, LCD driver module, locking and memory module, the mouth of optical sensor module connects the input end of signal processing module, the mouth of signal processing module connects the input end of LCD driver module, and the mouth of LCD driver module connects the input end of locking and memory module.
This device is placed on black and white LCD display panel on automotive rear-view light deflector, and by crossing automatic photoreceptor, induction high light below, then adjusts the Black-White of LCD, light transmission namely, thus can control the intensity of reflected light on light deflector, prevent the generation of dazzle.
Described optical sensor module consists of optical pickocff and related circuit.
Described signal processing module has contrasted with the light intensity signal that test obtains by the light intensity data of predetermined set, and chaufeur regulates preset value by switch is set.
Described LCD driver module comprises LCD display panel, is arranged on rearview mirror.
Described locking and memory module, by best LCD printing opacity value record, regulate automatically according to the size of light intensity.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
