Described servo-actuated projection subsystem also comprises snubber assembly, and this snubber assembly is located at can cause trickle vibration place of projected image on the swivel mount.
Compared with prior art, the utlity model has following advantage:
(1) display form novelty: servo-actuated optical projection system light harvesting is learned reflecting system and mechanism system and the whole body, break through traditional spectators and be in the static acting style that video is watched in a certain zone, make the in-plant video of watching of spectators, vision to spectators produces very big impact, and the screen of rotation has impetus for the expression of plot, spectators are immersed in the middle of the plot fully, thereby reach the purpose that attracts spectators, make spectators so enchanted by the scenery as to forget to return;
(2) synchronous playing is stable: guarantee every synchronous operation that demonstration maintenance and reference computer on each screen are demonstrated; Solve because the big ladder diagram image distortion that projector space causes;
(3) control simple general-purpose: solved various device has been realized exempting from completely programming, performance is analyzed to multimedia, has proposed the notion of Show, program and logical device; The screen motion control system has broken through traditional PLC control mode, adopt the control system of the SC-Brain32 formation of famous Control Software Medialon Manager and independent research, has outstanding extendability, can pass through the various lighting effects of multiple interfaces synchro control, video, audio frequency, machinery, special efficacy etc., and possesses Real Time Control Function, the fortuitous event that may occur in the middle of the performance process is controlled in real time and handled, by close friend's user interface, can allow the user very operate a large-scale show performance easily.
