Earth rotation 1 week is 24 hours, and it is about 365 days often to revolve around the sun one week, between the axis of the earth and day ground
Inclination angle is 66.5 °, remains that this inclination angle is constant when the earth revolves around the sun, the track that the earth revolves around the sun is ellipse
Circle, here it is occur the immediate cause of season alternation all over the world.
Annual March 21, sunlight just equably irradiate the half of earth's surface, and the equinox in this day is exactly at this time
The spring of northern latitude (Northern Hemisphere), southern latitude (Southern Hemisphere) autumn.Later, northern latitude (Northern Hemisphere) daytime by
It gradually lengthens, night is gradually shortened, and southern latitude (Southern Hemisphere) daytime is gradually shortened, and night gradually lengthens, annual June 21,22
Day, northern latitude (Northern Hemisphere) daytime reaches longest, and night reaches most short, and southern latitude (Southern Hemisphere) daytime reaches most
Short, night reaches longest；At this point, northern latitude (Northern Hemisphere) enters the cruel summer, southern latitude (Southern Hemisphere) is into severe winter.Again
Backward, northern latitude (Northern Hemisphere) daytime is gradually shortened, and night gradually lengthens, and southern latitude (Southern Hemisphere) daytime gradually adds
Long, night is gradually shortened, and annual September this day on the 23rd, sunlight can equably irradiate the half of earth's surface again, this day is round the clock
Divide equally, and be at this time the autumn in northern latitude (Northern Hemisphere), the spring of southern latitude (Southern Hemisphere).Followed by, north latitude
Degree regional (Northern Hemisphere) daytime continues to shorten, and night continues to lengthen, and southern latitude (Southern Hemisphere) daytime continues to lengthen, night after
It is continuous to shorten.When reaching annual December 21, northern latitude (Northern Hemisphere) daytime reaches most short, and night reaches longest, and southern
Latitude (Southern Hemisphere) daytime reaches longest, and night reaches most short；At this point, northern latitude (Northern Hemisphere) is into severe winter, it is southern
Latitude (Southern Hemisphere) enters the cruel summer.In cycles, season spring, summer, autumn and winter is just formed.Also it is therefore seen that, list is solid with regard to some
For fixed geographical location, the variation in season can be converted into the variation on date；
In the present embodiment, a certain big area in north, it is assumed that setting longest day in daytime (June 21) is turned on light for 20 points at night, daytime
Most short day (December 21) is turned on light for 17 points at night, then the time adjustment amount Δ t that daily night turns on light calculates as follows：
Δ t=(20-17) * 60*60/182.5=59.17s
From longest day in daytime excessively to most short day, per 59.17s is reduced day by day, excessively then need to increase to longest day from most short day
Add 59.17s, move in circles；
(4) if the control mode that user selects is remote control, PLC controls lamp according to the on-off signal that host computer is sent
Group LT1, LT2 and LT3 break-make；
(5) if the control mode that user selects is manual switch control, manual key lamp on manual operation panel
Group button SB12 SB11, SB22 SB21 and SB32 SB31 carry out the control of lamp group LT1, LT2 and LT3 break-make.
The method that the ginseng prosecutor formula control lighting lamp group selected according to user switchs for：
(6) if the ginseng prosecutor formula of user's selection includes rain control switch ginseng control, PLC judges whether rain control switch YK leads
It is logical, it is otherwise control lamp group LT1, LT2 and LT3 shutdown, lamp group LT1, LT2 or LT3 is controlled by selected Control Cooling；
(7) if user selection ginseng prosecutor formula include inductive switch ginseng control, PLC judge inductive switch GK1, GK2 or
Whether GK3 is connected, and judges whether the control condition for meeting selected Control Cooling, if two conditions all meet, controls lamp group
LT1, LT2 or LT3 are opened, and otherwise, if there is any one to be unsatisfactory in two conditions, turn off lamp group LT1, LT2 or LT3；
(8) if user selection ginseng prosecutor formula include audio-switch ginseng control, PLC judge audio-switch SK1, SK2 or
Whether SK3 is connected, and judges whether the control condition for meeting selected Control Cooling, if two conditions all meet, controls lamp group
LT1, LT2 or LT3 are opened, and otherwise, if there is any one to be unsatisfactory in two conditions, turn off lamp group LT1, LT2 or LT3.
PLC is according to headlamp main circuit voltage, control loop DC24V voltages and headlamp main circuit current and exchange
Alarm limit, direct-current control voltage alarm bound and each lamp group electric current alarm bound, failure voice controlling alarm above and below voltage
