As intelligent skylight adaptive system, its operation principle is referring to Fig. 7.Be that example describes light control principle figure with the Wuhan Area street lamp below, according to observation, Wuhan at dark between (various places are inconsistent) Summer Solstice about 19:45, the Autumnal Equinox, Winter Solstice was about 16:45, about Spring Equinox 18:35 about 18:35.Differed in the Summer Solstice and Winter Solstice 3 hours, weather is good in this way, from 19:45 in the Summer Solstice; Should reduce about one minute an of set time every day, reach 16:45 to Winter Solstice, increase about 1 packing afterwards every day; Reach 19:45 to the Summer Solstice, so circulation, its track is exactly to calculate datum line among Fig. 7.
But occurring in nature is cloudy, and the sleet sky all can make darkness change at day, and light sensor can reflect natural daylight actual change situation, yet light sensor can make susceptibility descend because of covering dirt, and has the erroneous judgement problem.Regularly wipe the scratch brushing dependent sensor with brush and can solve the dirt problem of covering; For the erroneous judgement problem, through observing, we find that as being standard determination to calculate datum line, the darkness that anomalous weather brings changes the overwhelming majority at day and is no more than 15 minutes, so we set up the restraining line to solve bias light interference erroneous judgement problem.Exceed with 15 minutes (the various places time is different).Light sensor provides signal time and computing time such as being no more than 15 minutes, provides signal time with light sensor and controls light, as surpassing 15 minutes, then adds deduct on the basis 15 minutes in computing time, is the light control time on the same day.Differing 15 minutes lines with the calculating datum line is exactly the restraining line among the figure, and the light sensor line of induction after the restriction is travel line among the figure.Travel line reflects 1 year darkness actual change situation basically.
18:35 in the Spring Equinox is set in the controller box of intelligent skylight adaptive system in advance, the Summer Solstice 19:45, the Autumnal Equinox 18:35, Winter Solstice 16:45, binding hours 15 minutes waits basic parameter (different regions can be provided with according to actual conditions).If D day is some day between the Summer Solstice and the Autumnal Equinox, computer at first calculates D day and turns on light fiducial time.The time difference T0 of lighting time change between the Autumnal Equinox in the Summer Solstice:
Fate (1) between T0=(Summer Solstice lighting time-Autumnal Equinox lighting time)/Summer Solstice and the Autumnal Equinox
T1 fiducial time turns on light D day:
T1=lighting time-T0 in the Summer Solstice * Summer Solstice and D be fate (2) between day
Half an hour before the every day T1, CPU begins the photosensor signal of sampling, T1 after binding hours T3 sampling finish.Sample 10 times be one group, three photosensitive useful signals that all sample then write down its sampling time T2, CPU relatively T1 is big or small with T2, less than binding hours T3 minute, then D day lighting time T equaled T2 like the two the absolute value of difference.Greater than T3 minute, then D day lighting time T equaled T1 and added deduct T3 minute like the two the absolute value of difference.D day, actual lighting time T was formulated:
T＝T2 (|T1-T2|≤T3) (3)
T＝T1+T3 (|T1-T2|＞T3，T1＜T2) (4)
T＝T1-T3 (|T1-T2|＞T3，T1＞T2) (5)
