Embodiment
Below embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
Please refer to Fig. 1, the invention provides a kind of Automatic control system of louver, comprising: illuminance sensor 1, for detecting the brightness value in work at present face; Motor 2, for the angle of adjusting louver window 5; Controller 3, is connected with illuminance sensor 1 and motor 2, controller 3 generate when the brightness value that illuminance sensor 1 detects is greater than the first brightness value for drive motor 2 the first drive singal with reduce described window shutter angle thus reduce brightness value.
Preferably, controller 3 is STC89C52 single-chip microcomputer.Preferably, motor 2 is can the direct current generator of rotating.Such as, this single-chip microcomputer can with DS1302 as clock chip, to provide basis of time for system.This single-chip microcomputer is also equipped with crystal oscillating circuit and reset and enable circuits, to form minimum Single Chip Microcomputer (SCM) system.Illuminance sensor 1 can be connected with P1.3, P1.4, P1.5 pin of STC89C52 single-chip microcomputer, with the data acquisition of controlled light degree sensor 1.
In one embodiment, preferably, if the brightness value that illuminance sensor 1 detects is more than 3000lex, carry out the angle of adjusting louver window by the first drive singal, brightness value is reduced, thus avoid sunshine direct projection, cause and dazzle light.
Owing to have employed technique scheme, the present invention can the angle of adjusting louver window automatically, has the advantages that structure is simple, cost is low.
Preferably, Automatic control system of louver also comprises LED 4, is connected with controller 3, for supplementary indoor illumination intensity; If in any case the brightness value regulating the angle of described window shutter that described illuminance sensor 1 all can not be made to detect is greater than the second brightness value, then described controller 3 generates the second drive singal for opening described LED 4 to open described LED 4.In one embodiment, such as, in cloudy day or the dusk, if no matter how window shutter angle regulates, the brightness value that illuminance sensor 1 detects all cannot be above 200lex, and now the second drive singal driving LED lamp 4 luminescence is with supplementary indoor illumination intensity.
