Abstract
A large screen intelligent geometric adjustment system is characterized in that an IR remote control is utilized to control screws (screws No.1-No.8) rotating and translating during geometric adjustment in front of a large screen, so as to perform geometric adjustment on images projected by a projector onto the large screen. Eight electric rotating sleeves corresponding to the screws No.1-No.8 are designed on the eight screws controlling image resizing and translation of the projector, and the IR remote control is utilized to control a controller to rotate leftwards and rightwards, thereby bringing convenience for the adjusting personnel to perform geometric adjustments in front of the screen.
Description
Technical field
The present invention relates to giant-screen geometry regulation technology, belong to special projection display technique applied technical field.
Background technology
It is generally that two people coordinate to regulate that current giant-screen geometry regulates, and a people is positioned between giant-screen maintenance (between rear-projection), and a people is positioned at giant-screen front end.Regulated by intercom call between two people.Giant-screen the former watch giant-screen grid situation, by intercom commander rear-projection between regulate personnel to regulate corresponding screw.There is following drawback in such regulative mode: between rear-projection, geometry regulates personnel to can't see the situation of change of image, and the language can only accepting personnel before giant-screen describes, and regulates very difficult.Between rear-projection, geometry regulates personnel while adjustment geometry, also will pay close attention to intercom and easily divert attention, and adjustment often easily occurs excessive, or too small, meanwhile regulates during eminence screen and there is certain potential safety hazard.Efficiency is also lower.
In order to overcome existing technical disadvantages, the present invention proposes a kind of intelligent geometry newly and regulating, only needing a people to regulate geometry side before screen.
Concrete technical scheme of the present invention is as follows:
The design of system architecture:
System tool overall architecture is connected to form by two piece of 3/4 circular arc steel disc, 4 micromotors (can bidirectional rotation) are respectively inlaid with under two pieces of steel discs, in each motor rotary head, cover has the sleeve of a fixed size, and sleeve can be enclosed within projector 1-8 screw, controls it and rotates.
Fig. 1, Fig. 2 show tool construction.
Telepilot forms:
Every cover system instrument is all furnished with an independently telepilot, telepilot devises 17 buttons and a led display pilot lamp.Press the power knob on telepilot, pilot lamp is bright, now can use a teleswitch and control and the rotation of operation micromotor.Corresponding two buttons (left-handed button and dextrorotation button) of each micromotor.
Fig. 3 shows the composition of telepilot.
Claims (4)
1. big screen intelligent geometry regulating system, it is characterized in that using Infrared remote controller to control in giant-screen front bar projectable machine regulates the screw of rotation and the translation used during geometry (corresponding to 1-8 screw respectively), to the image on giant-screen, geometry adjustment is carried out to projector.Design 8 electronic rotation sleeves (corresponding with 1-8 screw) on the screw of 8 control image zooming and panning of projector, Infrared remote controller controller is used to rotate (left-handed and dextrorotation), and then facilitate adjustment personnel to regulate geometry side before screen, geometry regulates and only needs one man operation, double compounding practice before replacing, more, efficiency is higher for effect.
2. infrared technique according to claim 1, is characterized in that arranging the button corresponding with screw projector controlling geometry in Infrared remote controller, and is divided into left-handed and dextrorotation two kinds.As: 1 left side, 1 right side, 2 left sides, 2 right sides, 3 left sides, 3 right sides, 4 left sides, 4 right sides, 5 left sides, 5 right sides, 6 left sides, 6 right sides, 7 left sides, 7 right sides, 8 left sides, 8 right sides.During by " 1 is left ", in projector, the sleeve of correspondence No. 1 screw controls (counterclockwise) rotation left of No. 1 screw, and during by " 1 is right ", in projector, the sleeve of corresponding No. 1 screw controls (clockwise) rotation to the right of No. 1 screw.
3. geometry regulation technology according to claim 1, is characterized in that having in projector the screw that four yellow, can the upper and lower movement in the left and right of control mesh when adjusting geometry.When moving to left, tight right pine is left; When moving to right, tight left pine is right; When moving down, in tight outside pine; On when moving, in tight outer pine.Also have the screw that four white in the outside of yellow screw, control the Scalable of four direction respectively.Projector has the individual screw stretched outside, can by moving left and right the deflection controlling whole grid.
4. regulating sleeve according to claim 1, sleeve type is divided into two kinds (each 4) to be interior Hexagonal jacket, a kind of corresponding with the translation screw in claim 3, another kind of corresponding with the convergent-divergent nut in claim 3.Above sleeve, respectively arrange one can control motor, by telepilot, rotation is carried out to it and control, use 3/4 annulus to be fixed according to the position of 1-8 screw in projector and order by 8 sleeves.
