Description
Technical field
The invention belongs to 3D technical field, particularly relate to a kind of 3D line holographic projections veil system.
Background technology
The stage form of expression, is generally by the action of real performer, expression and voice language, and shows in conjunction with stage background stage property.Along with development in science and technology, present stage is shown and is usually adopted the technology such as photoelectric technology, giant-screen background, makes stage produce various visual effect, makes virtual and truly organically to combine before the lights.Along with the development of 3D technology, present stage has incorporated 3D projection and human-computer interaction already; Meanwhile, in curtain technical development approach, also there is water curtain, water curtain is similar to motion picture screen, be planar imaging, also referred to as digital water curtain, its imaging picture is thin, lack thick and heavy sense, in the process of free-falling, may occur observing unclear situation, and due to hydraulic pressure control not easily, there will be picture distortion, affect bandwagon effect.For these shortcomings, veil shadow casting technique is thereupon raw, utilizes fog and air to carry out simulated projections screen, can delete stage entity screen, and the interaction of performer on 3D line holographic projections and stage is more true, does not have tomography sense.
Chinese patent CN 104516492A discloses a kind of human-computer interaction technology based on 3D line holographic projections, stereopsis is projected in space by 3D line holographic projections equipment, make user can 360 degree of comprehensive solid space images seeing real dimensions, and gesture can be relied on directly to manipulate on image, but need space and entity screen or reflectance coating, very large for limitations, be unfavorable for that stage shows, be unfavorable for equally showing on a large scale.Chinese patent CN203520100U discloses a kind of 3D digital water curtain system based on PLC, its structure comprises the parts such as solenoid valve array, water main, splashproof tank, water pump, PLC, frequency converter and pressure transducer, this utility model employs solenoid valve array for water curtain, stability and stereovision can be improved, but water curtain is due to the limitation of flowing, there will be picture distortion all the time.
Summary of the invention
Project industry for stage human-computer interaction sense not by force for solving 3D, and the problem of screen control dynamics difference, we have proposed a kind of 3D line holographic projections veil system, and adopt the present invention can reach stage expression effect good, limitations is little, the object that stability is high.
The present invention is achieved by the following technical solutions:
For achieving the above object, we have proposed a kind of 3D line holographic projections veil system, comprising PLC, light units, audio frequency apparatus, projection arrangement, veil device and stage, PLC is by signal circuit and light units, audio frequency apparatus, projection arrangement, veil device connects.Before the lights assembled arrangement is carried out to all devices, take PLC as control subject, each equipment is accurately controlled, reach good stage effect.
Light units is arranged on stage, described audio frequency apparatus is arranged on stage, described projection arrangement is arranged on stage outside, light audio frequency apparatus needs adjustment stage being carried out to each angle light audio, carry out irradiation position conversion at any time, projection arrangement is arranged on the outside ceiling of stage, synchronous with light units, carry out projection illumination, curtain is the veil that veil device generates, focus in veil top layer, water droplets is made to carry out light reflection to it, thus reach curtain effect, according to the distance of veil and projection arrangement, its focal length is controlled from PLC, and carry out detection adjustment in real time.
Veil device comprises water pipe, high-pressure atomizer, baffle plate, blower fan and mist arrester; Water pipe connects high-pressure atomizer, high-pressure atomizer is arranged on stage top, fog outlet is downward, baffle plate is arranged on high-pressure atomizer fog outlet side, it is one-sided that blower fan is arranged on high-pressure atomizer, and towards fog outlet, mist arrester is arranged on bottom stage relative with high-pressure atomizer, high-pressure atomizer, blower fan is directly connected with PLC with mist arrester.Deionized water after purification is atomized by high-pressure atomizer, from up to down spray, and by the formation of baffle plate and blower fan determination spray direction, speed, fogging degree, veil thickness, veil with rapidly disappear, carry out the overall situation by PLC to control, baffle plate mainly controls the veil of fog outlet amplitude of spraying, and regulating fender angle, controls veil injection direction and thickness, guarantee to carry out recovery circulation with mist arrester to veil, and puzzlement is not caused to stage.Blower fan mainly adjusts veil orientation angle, adjusts fan wind-force rotating speed and wind direction in real time according to project content, to adjust veil angle and thickness.High-pressure atomizer is also referred to as pressure nozzle, and its critical piece has the tangential population of liquid, liquid in rotation room nozzle bore etc.It mainly utilizes high-pressure pump to make liquid obtain very high pressure (2-20MPa), and enter the rotating room of people's nozzle from tangential population, liquid obtains rotary motion in rotating room.Its principle of work is according to spinning momentum square law of conservation, rotational speed with revolve thirsty radius and be inversely proportional to.Therefore, more near axle center, rotational speed is larger, its static pressure is also less, result forms one pressure in nozzle central authorities and equals atmospheric air swirl, liquid then forms the annular membrane rotated around air core, and fluid pressure can change proal liquid film drying process into and establish each kinetic energy at nozzle place, spray from nozzle.Liquid film extends thinning, is finally split into little droplet.The liquid mist of such formation is open circles taper, sprays also known as hollow cone.Pressure nozzle common feature structurally makes liquid obtain rotary motion, and namely liquid obtains centrifugal intertia force, then by nozzle bore ejection at a high speed.Veil is in atmosphere because gravity is less, tank can be fallen into rapidly unlike water curtain, veil is under nothing controls, due to molecule random motion and interaction force impact, can spread gradually, thus cause veil the latter half imperfect, therefore mist arrester is used, the recyclable veil of one side is recycled to high-pressure atomizer and is again atomized, the complete and stable of veil can be ensured on the one hand by controlling moisture movement direction, the corresponding high-pressure atomizer of each mist arrester, with man-to-man form, control a longitudinal component of veil, the width of veil is expanded by multiple combination, the height of veil is adjusted by the jet velocity of high-pressure atomizer and the air draught speed of mist arrester.
Preferably, above-mentioned veil device is 1-8 cover, and often overlap a longitudinal component of veil device composition veil, multiple veil is transversely arranged, carries out controlling and adjustment to the width of veil, also can rearrange and be combined into multilayer veil.
Preferably, above-mentioned veil thickness is 2-30cm, and the thickness of veil is the key of drop shadow effect, according to different 3D projection video recording, the thickness of adjustment veil, reflects according to light, find best projection effect, PLC is controlled, ensure the stable normal work of a whole set of veil device on stage.
Preferably, the atomizing particle size of above-mentioned high-pressure atomizer is 1-5 μm, and atomization quantity is 200-500ml/h.Water fog particle particle diameter is little, easily controls, and stability is high, and veil flatness is higher.
Preferably, above-mentioned mist arrester is with refrigerating plant, and in the process of inhaling mist, by condensation, dry moisture around, is beneficial to and reclaims circulation, using water wisely simultaneously.
Preferably, above-mentioned mist arrester is provided with metal filter screen, prevents impurity from entering circulation, affects veil effect.
Preferably, the filtering accuracy of above-mentioned metal filter screen is 50-200 μm.
The invention has the beneficial effects as follows:
