Description
Affiliated technical field
The utility model relates to the control of street lamp, a kind ofly especially adopts the multi-functional street lamp control of astronomical algorithm to put, and belongs to the electron controls technology field.
Background technology
Use at present more street lamp control technology remain manually according to daybreak darkness situation control, switch with the street lamp control cubicle closes at dark, at day the switch with the street lamp control cubicle disconnects, this manual operation causes the switch of street lamp untimely sometimes, and can not realize Long-distance Control or centralized monitor.
The technical scheme that some automatic switch lamps are also arranged at present, for example, CN87211553 utilizes a singlechip chip and one to be used to store switch lamp timetable every day that calculates according to nature astronomical time, by the program control switch lamp time of every day; CN96117835.3 and CN00210624.8 utilize opening or closing of beeper control street lamp.Summarize above scheme, have the following disadvantages: the one, astronomical time calculate according to nature by storage every day the switch lamp timetable the way limitation very big, the switch lamp timetable that can only store single place in the memory, the switch lamp actual needs that can not adapt to different location (longitude and latitude difference), different places must write different timetables, makes troubles to production; The 2nd, function ratio is more single, can not take all factors into consideration multiple situation.
At present have also that independent use is light-operated turns on light, but disturbed and misoperation easily.
At present also with good grounds longitude and latitude is determined the switch lamp time, but use is simple approximate calculation, and error ratio is bigger, has time error to differ and reaches more than ten minutes.Because the length on true solar day is with changing season, it changes the influence that mainly is subjected to two factors: the one, because the existence of ecliptic obliquity (23 ° 26 '), be the inclination of ecliptic plane for the equatorial plane, the sun is in annual motion, with respect to the celestial equator back and forth movement, cause all its annual change of length on true solar day; The 2nd, because the orbit of the earth is oval, the variation of solar distance, the speed of the revolution of the earth does not wait, and causes all its annual change of sun ecliptic longitude every day difference itself.These two factors act on and the phase mutual interference simultaneously, have caused the variation of length on true solar day.
The orbit of the earth is followed Kepler's planetary motion three laws, so sun set/raise time and be clocklike between daybreak at dark.Planetary motion first law (track law) show all planets respectively on the elliptic orbit that varies in size around solar motion, the sun is positioned at one of two focuses of planetary orbit ellipse.Planetary motion second law (area law) shows that in the same time planet radius vector inswept area on its orbit plane equates.Planetary motion the 3rd law (mendeleeff's law) shows the ratio in cycle that any two planets revolve around the sun square, equal they with the distance of the sun cube ratio.If T
