Description

Self-adapting frequency conversion animating means in the subway tunnel

Technical field

The utility model belongs to advertisement display technique field, particularly relates to a kind of frequency conversion animation display device of realizing in subway tunnel.

Background technology

Subway is as the critical facility of urban transportation, and the effect in people's daily life is more and more important.Only with Shanghai, come into operation and at tens lines of building that have, total length will reach more than 400 kilometer in 2010, planning the year two thousand twenty more will be up to more than 800 kilometer.

For the facility of scale like this, how to improve its environment looks and its exploitation advantage of performance, should not be underestimated in fact.Therefore, people are full of interest for carry out the trial that animation is realized in subway or tunnel always.Wherein also be no lack of various imaginations and patented claim.

But take a broad view of it, some biased part of neglecting one's supervisory duties seemingly arranged:

At first, considerable people thinks: when train in the tunnel during fast running, if there is the above continuous pictures of 10 width of cloth to come into view (or form) in p.s., people will obtain animation visual effect (basis of many patented claims promptly comes from this) according to the persistence of vision phenomenon.Big in fact also wrong.The persistence of vision phenomenon of eyes probably is 0.1 second, and the picture that people see from film was 24 frame/seconds, and the field-scanning period of TV is 50HZ, also be for 50 width of cloth/seconds (even staggered scanning, every width of cloth image scans at twice, and per second also has 25 width of cloth images to enter human eye); So the moving frame that we see is natural and tripping.But it is more unheeded easily that wherein important also is: no matter be movie or television promptly, when every width of cloth figure in screen (or screen), manifest, and and spectators' relative position all be static.Even as cinefilm, appear in the projector and to do to move continuously and fast, in the cooperatively interacting of its tangible intermittent drive mechanism (Maltese cross) and shadow shield, be stably to rest on the gate place in this time period to the screen in ray cast; Only when being blocked, light just is pulled through fast, in order to avoid the smear when manifesting film and moving by intermittent drive mechanism.Therefore, in the tunnel, only make fast moving with respect to the picture in the tunnel and picture remains freely brightly, expect that animation effect is impossible at all by train for those imaginations; Or even the frame frequency that passes through is high more, will present a slice of vast expanse of whiteness more.

Secondly, some patented claim has proposed employing narrow slit grating (or column mirror grating) and is equipped with the picture of compression establishment, also is unpractical in the hope of the imagination that obtains the animation visual effect.The grating principle is similar to three-dimensional imaging principle on the market, and promptly in the face of the same painting, two from different visual angles, and what see through narrow slit or post mirror is zones of different in the background frame.It still is feasible obtaining stereo-picture with the method, but just undertaken to do what is apparently beyond one's ability as obtaining animation effect: the making of relative assembly will be very difficult on the one hand, because of the width of grating and the compression of image are exactly a pair of contradiction: obtain meticulous resolution, then grating can not be wide; And grating is not wide, and then the compressed information of image is limited, does not allow too much image and is compressed; Moreover in the tunnel, even if in same device, compressed the information of multi-picture, in the subway carriage of operation, at the most also only can by way of the time, sight line is watched attentively it from different perspectives, and is also just unsustainable after obtaining the information of these a few width of cloth pictures.Because of it can only be isolated the existence, can not keep continuity.

Though above-mentioned imagination has such-and-such defective, we think, in subway or tunnel environment, even can't reach the effect (because of the relative motion of train and picture can't be avoided) of movie or television, but make every effort to minimum input,, still can do some trial in the hope of true to nature as much as possible.

The utility model content

The purpose of this utility model provides a kind of device that can realize the frequency conversion animation display in subway tunnel, to solve this type of device poor effect of the prior art, the high enterprise of cost and to restrict problems such as much.

Technical scheme

The purpose of this utility model is achieved through the following technical solutions.

Self-adapting frequency conversion animating means in the subway tunnel comprises animated image, stroboscopic light source and speed of a motor vehicle isochronous controller; It is characterized in that: described animated image be in subway or the train tunnel wall, in the compartment occupant see through that vehicle window can conveniently be looked and the position on, along a series of plane pictures that are progressive differentiation of the equidistant setting of garage's direction; Described stroboscopic light source on railway car lateral surface appropriate location, the directional light sources that triggered by the trigger pip of speed of a motor vehicle isochronous controller, can shine over against animated image; Described speed of a motor vehicle isochronous controller is worked as consistent with respect to the travel frequency of garage with animated image to the triggering frequency of stroboscopic light source.

Described animated image fixes, also can collect easily with known usual manner and tunnel wall, can use by turns for each segment of subway; The adjacent animated image and the relative position of train allow progressive change.

Described stroboscopic light source is the directed stroboscopic lamp of high-power, variable ratio frequency changer, short pulse formula.

Described isochronous controller can be mechanically, as realizing by mating with the rotation in Train Wheel week.

Adopt the technical program, in use, even after train sails the tunnel into speed reach can make isochronous controller post a letter when frequently being equal to or greater than 10 times/second, also relevant stroboscopic lamp also can be equal to or greater than 10 times/second the picture projection light of frequency on tunnel wall according to the time, for the occupant on the train, because of the persistence of vision phenomenon just can have been experienced animation effect true to nature; Because stroboscopic frequency and the speed of a motor vehicle are synchronous, when the speed of a motor vehicle heal when fast stroboscopic picture that is also fast, train process simultaneously just the more animation develop also sooner, vice versa, both remain unanimity, have demonstrated fully the adaptivity of this device.

Embodiment

Self-adapting frequency conversion animating means in (embodiment) subway tunnel

Further describe structure of the present utility model below in conjunction with accompanying drawing.

Shown in Figure 2 as Fig. 1, in subway or train tunnel wall, along garage's direction, in the compartment occupant see through that vehicle window can conveniently be looked and the position, a series of continuous animation images are set.Picture traverse (connect spacing) unsuitable wide (for example can be set at 1000mm), and highly suitably (but needn't stick to depth-width ratio, promptly allowing is to exceed the 1000mm that width is set, with the increase effective area).

Picture is not established illumination, especially without the lamp box form.This measure both can be saved investment, and was also energy-conservation, and can not produce interference to train driving.

Picture fixes with plain mode and tunnel wall front.Can not move, also can conveniently collect and can use by turns as long as picture safety can be fixed for each segment of subway.So that input-output efficiency maximization.

In railway car lateral surface appropriate location,,, some stroboscopic light sources are installed over against picture such as vehicle window upper edge (eaves).Train is provided projection source for oneself, can be provided with by actual needs, and only when train process respective section picture be worked, and both energy-conservation, the investment-saving is also avoided the vehicle in travelling is produced interference again.

Stroboscopic light source should be high-power, variable ratio frequency changer, short pulse formula stroboscopic lamp.The quantity number is decided on requiring effect.All stroboscopic lamps are directed form over against picture, to also noiseless in the compartment; And relevant stroboscopic lamp is controlled by same controller.The stroboscopic controller then with locomotive garage synchronization of rate (for example by above-mentioned image spacing be set at 1 meter limit vehicle whenever advance 1 meter just trigger stroboscopic once).More can be directly mechanically, as realizing by mating with the rotation in wheel week.Both simple and effectively and trend towards making system standardization.

In the life, we notice that the thunder and lightning when night in summer streaks sky, and the pedestrian in the dark is seemingly static when lightning.Reason just is the very brief moment with respect to lightning, because of the persistence of vision phenomenon, makes the mobile masked and difficult quilt of low speed discover.

With the above-mentioned example that is set to, be earlier stroboscopic controller setting condition of work: promptly when train speed was lower than 10 meter per seconds (36 kilometers/hour) or do not enter tunnel (/ do not enter animation section), then the stroboscopic controller was not worked; And enter tunnel and speed when exceeding 10 meter per seconds (36 kilometers/hour) when train, the controller synchronous with the speed of a motor vehicle (/ or wheel) then sends trigger pip by the frequency of 1 time/meter (referring to that picture traverse (connecting spacing) has been set at 1 meter) to relevant stroboscopic lamp, and the relevant stroboscopic lamp of order also throws very brief (preferably less than 1ms) and the illumination of enough bright (referring to that the occupant can normally view and admire in the compartment) with 1 time/meter frequency to the picture of tunnel wall.The duration of strobe light is short more, and then the smear of picture is also short more, and image quality is just good more; Duration as strobe light is 1ms, when the speed of a motor vehicle is 36 kilometers/hour, just has the smear of speed of a motor vehicle x duration (10 meter per second x1 millisecond)=10mm; When the speed of a motor vehicle is 72 kilometers/hour, then have the smear of 20mm.

Picture interval outside the compartment is made as 1 width of cloth/rice, and the stroboscopic frequency also must be 1 time/meter (the two only must be synchronously just); Like this, when the frequency of per second during greater than 10 times, seeing through picture that vehicle window sees and just as if being has per second greater than 10 times gradual change on relatively-stationary position, thereby obtains animation effect true to nature.

Certainly,, see through vehicle window and just may see simultaneously that several identical animations are arranged,, make also that the occupant can both view and admire from different visual angles in the compartment just like there being several televisors to play at the same time because of only 1 meter of picture interval.So configuration, even the distance of compartment and picture or the position between adjacent pictures just have a little gradual change also unimportant (so, environment requirement is just seemed looser), how many steps how many steps are people just as walking close to or retreating, squat down or stand and why not have before the televisor of a series of proper alignment? even thereby the effect embodiment that also has very excites people to create new artistic conception on animated content.

Because the stroboscopic frequency becomes with the speed of a motor vehicle, no matter train speed change how in the tunnel all will can not influence animation effect.Only the speed of a motor vehicle is fast, and the variation of animation is also correspondingly fast, and vice versa, demonstrated fully the adaptivity of this device.So, make technology implementation become very simple and adaptability greatly strengthens.More can be advertisement career and open up a kind of brand-new form a brand-new field.
