Description
Technical field
The utility model relates to a kind of single channel formula digital astronomical phenomena instrument for the demonstration chronometer phenomenon.
Background technology
Planetarium is mainly used in performing in real time the various chronometer phenomenons of fixed star on celestial sphere, planet, nebula, cluster etc., is used for imparting knowledge to students, viewing and admiring etc.early stage planetarium is generally the optics planetarium, the main bulb that adopts, optical lens, eyeglass and the starboard of making in advance, usually can show on the earth macroscopic 6, the fixed star of 000 left and right, for bringing the most real starry sky, spectators experience, but the limitation due to the light source imaging, make the grade of star of optics planetarium performance lower, brightness is low, and in the optics planetarium, bulb is subjected to the restriction in serviceable life, bulb is easier to damage, affect drop shadow effect, what occur in the optics planetarium in addition is the star that isolates, there is no line or assistant images between star and star, can only reflect the fixed star sky, and sometimes become error.The planet sky can not be reflected, particularly planetary motion can not be effectively demonstrated; Can not reflect the variation of meteor shower; The starry sky that can not provide the different magnitudes of the use that is conducive to impart knowledge to students changes; Astronomical coordinate system display system single (can not all reflect equatorial coordinate, horizontal coordinate, equatorial circumference, zodiacal circle, meridian circle, horizontal circle, constellation line, constellation circle territory line etc.), can not recall astronomical historical events, the astronomical development of can not looking forward to the future.Therefore can't understand the rule of development and the evolutionary process of celestial bodies motion; Can not scheme by image display sky constellation art; Can not words identification starry sky celestial body, can not demonstrate the celestial body fine structure, as the satellite sky arrangement architecture of Jupiter, Saturn's rings, day body structure etc. is arranged in moon crater in the nebula cluster.Can not demonstrate various chronometer phenomenons, as equating solar eclipse, the moon; Can not provide the uranology feature of celestial body, the local time difference, position of heavenly body and parameter of celestial body (size, magnitude and spectrum etc.) sunset sunrise actual time, rise the actual time that falls by the moon, phases of the moon time true, star the moon and rise the star data such as the time is true that fall; Sky in the time of can not demonstrating daytime on daytime (containing the atmospheric envelope effect); Can not carry out multi-faceted, many environment and watch starry sky (diverse geographic location, the earth and space are watched starry sky); Can not show ground fog effect; Can not auto finding star; Can not follow the tracks of celestial body; Cardinal point (all directions) is on-the-spot non-adjustable; Motor pattern is simple, can not be synchronously, many speed shows sky; Structure is too complicated, because classical planetarium adopts hardware facility substantially, all must add a cover autonomous device for increasing a certain function, so whole system is scattered, complexity.The numerous and jumbled not only synchronous working of device systems is poor, and system is very unstable and often break down, and learning manipulation is very difficult simultaneously.As just needing to increase a cover direction projector in order to increase this simple functions of basic point (all directions direction).
Along with the development of digitized video technology, produced gradually the digital astronomical phenomena instrument, but its asterism image of existing digital astronomical phenomena instrument is not too clear; The asterism image melts the limit distortion, and its vertical wrapping angle is little, can not meet the demands.
