Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
It is more easy to be readily appreciated by one skilled in the art with feature, thus protection domain of the present utility model is made apparent defining.
A kind of air-conditioner controller based on low-light level sensor, as it is shown in figure 1, replace tradition automatic air condition with low-light level sensor
Sunlight sensor., low-light level sensor is combined with the control button of middle empty station meanwhile, use and outer not affecting button
In the case of sight, reach equally to regulate the technique effect controlling automatic air condition mode of operation according to sunlight size.
It should be noted that owing to maximum innovation of the present utility model is that air-conditioner controller is except by being arranged on
Low-light level sensor in button replaces original sunlight sensor, and the system of air-conditioner controller is according to the difference got equally
Magnitude of voltage carries out corresponding operation, and other control parts are similar with air-conditioner controller of the prior art.In like manner, based on
Described above, we can all regard sunlight sensor and low-light level sensor as light detector unit, in addition, light
Detector unit can also is that the photosensitive components and parts such as a kind of photoconductive resistance.Concrete system architecture includes light detector unit, AD conversion
Module and processing unit.Wherein processing unit includes that control signal input, air-blower control outfan and refrigeration control are defeated
Go out end.The outfan of light detector unit connects the control signal input of described processing unit, this control by AD conversion module
Signal input part processed is for obtaining the output signal of light detector unit, and air-blower control outfan is then for going out to on-board air conditioner
Wind system output controls the control signal of rotation speed of fan, and refrigeration control outfan is for exporting control to the refrigeration system of on-board air conditioner
The control signal of system refrigeration intensity.
In terms of light detector unit, employed in the present embodiment is low-light level sensor, the light inspection in the present embodiment
Survey at least one button that low-light level sensor is arranged console by unit, therefore this button can be regarded as a light
Detector unit.Preferably, this button can also be that a display lamp etc. is internally formed lighttight fire dam body component.
As in figure 2 it is shown, include when it is as a button: low-light level sensor 6, keycap 1, key casing 3, pcb board 5 with
And light-guiding pillar 2.Wherein, key casing 3 is for receiving above-mentioned each parts.A kind of preferably structure situation implemented as this,
Key casing 4 can be the tubular structure of a both ends open.Keycap 2 is after the first opening of key casing 4 enters key casing
It is stuck in the second opening part, simultaneously by a bonnet 8 by the first closure of openings, makes keycap 1, bonnet 8 and key casing 3 enclose
For receiving the closed cavity of low-light level sensor 6 parts such as grade.
It addition, pcb board 5 is fixed in key casing 3, low-light level sensor 5 is welded on pcb board 5, in order to make low-light sense
Extraneous light situation experienced by device 6, is provided with a light-guiding pillar 2 between low-light level sensor 6 and keycap 1, this light-guiding pillar 2 one end
Portion is arranged on above low-light level sensor 6, and the other end props up key 1 surface, and keycap 1 and light-guiding pillar 2 corresponding position are provided with light hole 11.
By said structure, extraneous light can be transmitted at low-light level sensor 6, due to light hole by light-guiding pillar 2 from light hole 11
The size of 11 is less and the relation of light-guiding pillar 2, arrives the light of low-light level sensor 6 receptive field few, works as solar irradiation
Time the biggest, brightness is also the highest, and light strengthens the most therewith, and the signal amplitude that low-light level sensor 6 is exported is the biggest.Owing to low-light passes
Signal produced by sensor is analogue signal, it is therefore desirable to by AD conversion module, the light luminance of low-light level sensor perception is turned
Being changed to digital signal, processing unit compensates leaving air temp and wind speed by parameter calibration, to change at sunlight in reaching car
In the case of can maintain comfortable effect.
Preferably, low-light level sensor 6 model can but be not only limited to BH1620FVC-E WOSF5, simultaneously as reference
Ground, processing unit can use based on the process circuit that Renesas 78K0R/Fx3 is main control chip, in this main control chip
It is integrated with AD conversion function, but in other embodiments, AD conversion module can be independently of beyond processing unit.Above-mentioned
Model is possible of a kind of enforcement, the most in like manner possess the chip identical with above-mentioned chip functions and circuit can also enter
Row is implemented.It is understood that the present embodiment is simply illustrated for one, rather than the restriction of protection domain.
In order to prevent veiling glare from affecting, light-guiding pillar 2 side is light tight.Specifically by coating light tight coating or can paste
Protective film realizes.
When button 1 is provided with display lamp 7, display lamp 7 is generally also arranged on pcb board 5, in order to prevent display lamp 7 to micro-
The impact of optical sensor 6, needs to arrange division board 4 on pcb board 5, and this division board 4 is fitted on pcb board 5, on division board 4 with
Display lamp 7 and low-light level sensor 6 corresponding position are respectively arranged with through hole, simultaneously at the through hole edge convex of display lamp 7 correspondence
Rise and form annular lattice gear 41.The light preventing display lamp 7 has influence on low-light level sensor 6.Under preferable case, annular lattice gear 41 extension
Near keycap 1 inner surface.It should be understood that keycap 1 surface is also correspondingly provided with the logical light texture 12 for representing keypress function.
Above in conjunction with accompanying drawing, embodiment of the present utility model is explained in detail, but this utility model is not limited to
Above-mentioned embodiment, in the ken that those of ordinary skill in the art are possessed, it is also possible to without departing from this utility model
On the premise of objective, various changes can be made.
