Abstract
The invention relates to an electronic anti-dazzling automobile inside rear-view mirror. Currently, a conventional electronic anti-dazzling automobile inside rear-view mirror utilizes a pure hardware circuit to control the regulation of the reflectivity of an EC (electrochromic) mirror surface and utilizes different hardware circuits for EC mirror surfaces of different sizes and types. Therefore, the electronic anti-dazzling automobile inside rear-view mirror only utilizes one control circuit and the support of hardware and software, when the front light intensity of the EC mirror surface is greater than the rear light intensity of the EC mirror surface, a high voltage is output to the mirror surfaces as required to enable the EC mirror surfaces of different sizes and types to be in rapid electrochromism, and then the voltage of the EC mirror surface is reduced to enable the EC mirror surface to work normally in a long-term deep anti-dazzling state at lower voltage; and on the contrary, when the front light intensity of the EC mirror surface is smaller than the rear light intensity of the EC mirror surface, the dual-electrode of the mirror disappears, and the EC mirror surface can quickly fade and restore to be in an original clear and non-anti-dazzling state. The electronic anti-dazzling automobile inside rear-view mirror has the advantages of reducing the design cost and shortening the development cycle of the EC mirror surfaces of different sizes and types of the electronic anti-dazzling automobile inside rear-view mirror.

Summary of the invention
The objective of the invention is to propose solution at the weak point of above-mentioned existing electronics anti-glare vehicle inside rear-view mirror technology, adopt a kind of circuit, by software control and adjustment, be applicable to the electronics anti-glare vehicle inside rear-view mirror of any specification and kind, reach required electronics anti-dazzle effect and permanent normal useful life.
The present invention proposes a kind of design plan of electronics anti-glare vehicle inside rear-view mirror
Comprise electronics anti-glare vehicle inside rear-view mirror EC minute surface, micro controller system and peripheral circuit, quick-reset circuit, computing and control circuit, former and later two photosensors, the light intensity testing circuit, the control circuit that power-switching circuit etc. are formed, this control circuit is after former and later two photosensors of electronics anti-glare vehicle inside rear-view mirror are gathered the front and back light intensity, the front and back light intensity that the light intensity testing circuit will collect is judged, when light intensity before the electronics anti-glare vehicle inside rear-view mirror greater than back light intensity or back light intensity during less than preceding light intensity, at once be transferred to micro controller system, micro controller system calculates according to blas again, and according to the light intensity extent, on request high voltage is applied to electronics anti-glare vehicle inside rear-view mirror EC minute surface the two poles of the earth in short-term, make the electronics anti-glare vehicle inside rear-view mirror EC minute surface electrochromism rapidly on request of different size and kind, come to change rapidly on request electronics anti-glare vehicle inside rear-view mirror EC mirror reflectivity with this, and then through quick-reset circuit and computing and control circuit, in time reduce by two pole tensions of electronics anti-glare vehicle inside rear-view mirror EC minute surface to reasonable value, to reach electronics anti-glare vehicle inside rear-view mirror EC minute surface after having realized rapidly no-glare under the high voltage, also can keep down in the degree of depth no-glare state normal operation always in low voltage, otherwise, current light intensity is less than back light intensity or back light intensity during greater than preceding light intensity, EC minute surface two pole tensions of electronics anti-glare vehicle inside rear-view mirror disappear immediately, and electronics anti-glare vehicle inside rear-view mirror EC minute surface will fade and return to clear no anti-dazzle state originally fast this moment.
Beneficial effect of the present invention
The EC minute surface that has solved different size and kind is assembled into the problem that electronics anti-glare vehicle inside rear-view mirror can only be mated different circuit on request, by software control, the electronics anti-glare vehicle inside rear-view mirror that makes a kind of circuit can mate different size has reduced design cost and the R﹠D cycle of the electronics anti-glare vehicle inside rear-view mirror of different size.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is the functional block diagram of invention
Among Fig. 1, (1) power-switching circuit, (2) preceding photosensor, (3) back photosensor, (4) light intensity testing circuit, (5) micro controller system and peripheral circuit, (6) quick-reset circuit, (7) computing and control circuit, (8) electronics anti-glare vehicle inside rear-view mirror EC minute surface.
The specific embodiment
In Fig. 1, start under the total power supply state of back (1) power-switching circuit at automotive ignition, at (2) preceding photosensor, (3) after the photosensor collection of back when car light light and surround lighting, (4) the light intensity testing circuit front and back light intensity that will collect judge have or not before and after light intensity difference, when light intensity before the EC minute surface greater than back light intensity or back light intensity during less than preceding light intensity, be about to judge and be transferred to (5) micro controller system and peripheral circuit, (5) micro controller system and peripheral circuit calculate according to blas again, and according to the light intensity extent, warp (7) computing and control circuit are applied to high voltage the two poles of the earth of (8) electronics anti-glare vehicle inside rear-view mirror EC minute surface in short-term on request, make (8) electronics anti-glare vehicle inside rear-view mirror EC minute surface electrochromism rapidly on request of different size, can change the reflectivity of (8) electronics anti-glare vehicle inside rear-view mirror EC minute surface on request with this, then, again by (6) quick-reset circuit, in time reduce the EC minute surface voltage of (8) electronics anti-glare vehicle inside rear-view mirror to reasonable value through (7) computing and control circuit again, with this (8) electronics anti-glare vehicle inside rear-view mirror EC minute surface that has reached different size and kind after having realized rapidly no-glare under the high voltage, also can be under low voltage normal operation always in degree of depth no-glare state for a long time; Otherwise, when light intensity before the EC minute surface less than back light intensity or back light intensity during greater than preceding light intensity, also at once judgement is transferred to (5) micro controller system and peripheral circuit, (5) micro controller system and peripheral circuit calculate according to blas again, and according to the light intensity extent, warp (7) computing and control circuit are not applied to voltage the two poles of the earth of (8) electronics anti-glare vehicle inside rear-view mirror EC minute surface immediately on request, thus, (8) the two poles of the earth loss of voltage of electronics anti-glare vehicle inside rear-view mirror EC minute surface, subsequently, (8) electronics anti-glare vehicle inside rear-view mirror EC minute surface will fade and return to clear no anti-dazzle state originally fast.
