Description
Technical field
The present invention relates to the virtual material technology of variable light transmission field, especially relate to a kind of control system and implementation method for the virtual material of the variable light transmission of vehicle glass.
Background technology
The control system of the virtual material of variable automobile light transmission of existing market adopts photoelectric sense technology and glass transmittance detection technique more.Photoelectric sensor is generally made up of light source, optical path and photovalve three parts, and its ultimate principle is taking photoelectric effect as basis, measured variation is converted to the variation of light signal, then further converts light signal to electric signal by photovalve.When irradiation jobbie, can be regarded as a succession of photon bombardment with certain energy on this object, now photon energy just passes to electronics, and the whole energy that are a photon are absorbed by an electron institute once, after electronics obtains the energy of photon transfer, its state will change, thereby makes to be subject to light-struck object to produce corresponding photoelectric effect.Transmittance detection technique ultimate principle is, when the parallel beam of visible ray sees through glass, part light is absorbed by glass by a reflection of glass surface part, another part sees through glass-reflected, the number percent of light intensity and incident intensity is called reflectivity, and the number percent that absorption light intensity and people penetrate light intensity is called absorptivity.See through the number percent that light intensity and people penetrate light intensity and be called transmitance or transmittance.And the light that sees through glass is divided into directional light and scattered light, the number percent that the directional light intensity seeing through and people penetrate light intensity is called penetrability, and directional light just can imaging in people's eyes.
In the Control System Design of the virtual material of the variable light transmission of vehicle glass in crucial two technology, what tool optimization was worth is that glass transparency detects this technology.
Pocket Detective2.1Window Tint Meter is the Portable glass light transmittance detector by the development of MONROE company of the U.S., for detection of automobile coloured glass, and all kinds of glasses, sunglasses, the transmittance of preventing coating protection film.It adopts LED light source, and measuring accuracy can reach 2%, and sensitivity is 0.1%; Power with 9V pond, electric current when whole system work is 13.5mA.
