Description
Technical field
The utility model relates to a kind of multimedia overhead projector demo system, especially a kind of multimedia overhead projector demo system that can be used for geographical and astronomical teaching.
Background technology
The multimedia ball-screen projection demonstrator of at present geography class teaching usefulness, generally only has the ball-screen projection function, namely can only demonstrate in spherical screen, the projection of realization on sphere, and the planetarium that can't carry out when astronomical teaching on dome is demonstrated, and independent digital astronomical phenomena instrument volume is very large, need to take independent place, the switching when being not easy to impart knowledge to students.
Chinese patent ZL20112053134.0 discloses a kind of multimedia ball-screen projection demonstrator, its structure comprises ball curtain, base, ball curtain camera lens, projector and computing machine, ball curtain bottom is provided with an opening, and ball curtain camera lens is installed in the opening, and ball curtain camera lens links to each other with projector.The demonstrator of this structure still can only carry out the projection on the sphere, can't carry out the planetarium demonstration on the dome.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned the deficiencies in the prior art, and a kind of planetarium demonstration that can carry out when astronomical teaching on dome is provided, and the dual-purpose multimedia overhead projector demo system of ball curtain, dome that also can carry out projection on the sphere.
The technical solution adopted in the utility model is as follows:
A kind of ball curtain, the dual-purpose multimedia overhead projector demo system of dome, it includes fish eye lens, fish eye lens is arranged on the projector image output port, the signal input part of projector links to each other with the signal output part of computing machine, projector is installed in the base, it is characterized in that: the below of described projector is provided with lifting table, and described fish-eye top is provided with the ball curtain, one opening is arranged at ball curtain bottom, and fish eye lens is positioned at this opening center; Or fish-eye top is provided with dome.The utility model also arranges lifting table below base, with the projector in base, the base and fish eye lens one lifting thereof.
It is inner or outside that described computing machine is placed in base.
The beneficial effects of the utility model have:
Simple and practical, easy to use, the ball curtain multimedia overhead projector demo system that the geographical teaching of numeral can be used and the synthetic integral body of dome multimedia overhead projector demo system active set, thrift education resource, when carrying out geographical teaching and astronomical teaching, can switch at any time, very convenient.
