Abstract
The invention relates to a method for controlling the speed of electrochromism of EC mirror planes. Currently, pure hardware circuits are adopted to control the speed of the electrochromism of traditional EC mirror planes, the hardware circuits need to be used normally for a long time, and different hardware circuits need to be adopted according to the EC mirror planes with different sizes and types. As a result, the invention provides the scheme that only one control circuit is needed, under the supporting of software and hardware, when front light of the EC mirror planes is stronger than back light of the EC mirror planes, a higher voltage is transmitted to the EC mirror planes according to the requirements, then the EC mirror planes with different sizes and types are made to quickly carry out the electrochromism, and then the voltages of the EC mirror planes are reduced timely to enable the EC mirror planes to work normally in a deep anti-dazzling state under a lower voltage; otherwise, when the front light of the EC mirror planes is weaker than the back light of the EC mirror planes, voltages of two electric poles of the EC mirrors disappear, and at the moment, the EC mirror planes can quickly fade and recover to be in an original clear non-anti-dazzling state. The method for controlling the speed of the electrochromism of the EC mirror planes has the advantages that design cost and a research and development cycle of the EC mirror planes with the different sizes and types are reduced.
Description
Art
The present invention relates to a kind of EC minute surface electrochromism speed control method, especially under same circuit, by the high low-value variation of software control computing and hardware control circuit output voltage, the EC minute surface (electronic anti-dazzle eyepiece face) of different size and kind can be mated, and guarantee that the EC minute surface of different size and kind achieves rapidly after anti-glare under high voltage in short-term, also normally can work in degree of depth anti-glare state for a long time under low voltage maintains always, in addition, when EC minute surface the two poles of the earth no-voltage, EC minute surface can fade fast and return to originally clear without anti-dazzle state.
Background technology
At present, traditional EC minute surface electrochromism speed controls, after the power by surround lighting before and after EC minute surface being detected, pure hardware circuit is utilized to control to change the reflectivity of EC minute surface, reduce with this and stimulation is dazzle the eyes to human eye, such technology, more to the requirement restriction ratio of EC minute surface, the EC minute surface of different size and kind must adopt different hardware circuits, or regulating circuit build-out resistor, otherwise mate bad, the EC minute surface of different size and kind achieves rapidly after anti-glare at higher voltages, just can not also normally work in degree of depth anti-glare state at higher voltages for a long time always.
Summary of the invention
The weak point that the object of the invention is for above-mentioned existing EC minute surface electrochromism speed control technology proposes solution, adopt a kind of circuit, by software control and adjustment, be suitable for different size and different types of EC minute surface, reach required EC minute surface electrochromism speed control overflow and permanent normal term of life.
The present invention proposes the embodiment that a kind of EC minute surface electrochromism speed controls
Comprise EC minute surface (electronic anti-dazzle eyepiece face), single-chip microcomputer and peripheral circuit, quick-reset circuit, computing and control circuit, two light sensors, light intensity detection circuit, the composition control circuit such as power-switching circuit, two, the both sides light sensor collection separately after surround lighting before and after EC minute surface of this control circuit, the both sides environmental light intensity collected judges by light intensity detection circuit, when the front light intensity of EC minute surface is greater than rear light intensity or rear light intensity is less than front light intensity, at once single-chip microcomputer is transferred to, single-chip microcomputer calculates according to blas again, and according to front, rear light intensity extent, through computing and control circuit, high voltage is applied to EC minute surface the two poles of the earth on request in short-term, make the EC minute surface electrochromism rapidly on request of different size and kind, specular reflectance is changed on request with this, and then through quick-reset circuit and computing and control circuit, timely reduction EC minute surface two pole tension is to reasonable value, reaching EC minute surface with this achieves rapidly after anti-glare at higher voltages, also normally can work in degree of depth abblendbar state for a long time under low voltage maintains always, otherwise, when the front light intensity of EC minute surface is less than rear light intensity or rear light intensity is greater than front light intensity, EC minute surface the two poles of the earth loss of voltage, this moment EC minute surface will fade fast and return to originally clear without anti-dazzle state.
Beneficial effect of the present invention
The EC minute surface solving different size and kind can only mate the problem of different circuit on request when being assembled into the products such as electronic anti-dazzle order inside-automobile rear mirror, pass through software control, make a kind of circuit can mate the EC minute surface of different size and kind, decrease design cost and the R&D cycle of the product of the EC minute surface adopting different size and kind.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is the theory diagram of invention
In Fig. 1, (1) power-switching circuit, (2) front light sensor, (3) light sensor afterwards, (4) light intensity detection circuit, (5) single-chip microcomputer and peripheral circuit, (6) quick-reset circuit, (7) computing and control circuit, (8) EC minute surface.
Embodiment
In Fig. 1, under (1) power-switching circuit power supply state, at (2) front light sensor, (3) afterwards light sensor collection separately surround lighting time, (4) light intensity detection circuit is by before collecting, rear light intensity carries out having judged whether front and back light intensity difference, when the front light intensity of EC minute surface is greater than rear light intensity or rear light intensity is less than front light intensity, at once judgement is transferred to (5) single-chip microcomputer and peripheral circuit, (5) single-chip microcomputer and peripheral circuit calculate according to set program again, and according to front, rear light intensity extent, on request high voltage is applied to the two poles of the earth of (8) EC minute surface in short-term through (7) computing and control circuit, make (8) EC minute surface electrochromism rapidly on request of different size and kind, EC specular reflectance can be changed on request with this, again, again by (6) quick-reset circuit, pass through (7) computing again and control circuit reduces the voltage of (8) EC minute surface in time to reasonable value, reaching different size and different types of (8) EC minute surface with this achieves rapidly after anti-glare at higher voltages, also normally can work in degree of depth abblendbar state under low voltage maintains always, otherwise, when the front light intensity of EC minute surface is less than rear light intensity or rear light intensity is greater than front light intensity, also at once judgement is transferred to (5) single-chip microcomputer and peripheral circuit, (5) single-chip microcomputer and peripheral circuit calculate according to blas again, and according to light intensity difference size, immediately voltage is not applied to (8) EC minute surface the two poles of the earth on request through (7) computing and control circuit, thus, (8) the two poles of the earth loss of voltage of EC minute surface, subsequently, (8) EC minute surface will fade fast and return to originally clear without anti-dazzle state.
