Description

Prism tunnel motor vehicle space shows system
Technical field
The present invention relates to photoelectric display technical field, the three-dimensional display system in tunnel is especially for, more specifically Say that being related to a kind of prism tunnel motor vehicle space shows system in ground.
Background technology
With the development of subway and other tunnel Vehicular systems, people select more convenient mode to go on a journey, and 98.7% Audient represent to see underground tunnel advertisement during subway is taken after prompting, the whole nation more than 200 is organized resource and can realized Each main transfer point in city and comprehensive covering of main flow consumption circle.Therefore, within the enclosed space, passenger is in high-speed mobile A series of continuous high clear colorful animations are seen on subway, the visual experience of shock can be brought.
And existing tunnel shows system mainly using two kinds of technologies, one kind is static led display screens, it is necessary to be arrived 200 It is continuous in 800 meters of tunnel wall to install 400 to 800, by limiting the visual of every individual picture of width being arranged in tunnel wall Angle, when train high-speed motion, make be arranged on tunnel wall on picture with passenger's relatively fixed position one by one Quickly flash, so that passenger experiences animation effect.Make this advertisement need to take during design first video recording or Person has shot ad content, then resolves into the continuity image of fixed frame frequency by related software, and these images are spelled It is connected into continuous pictures, then deliver advertising pictures on LED display in order by control centre.For frame stabilization, lead to The speed of service between the station of the lower subway train of first actual measuring and calculating is often needed, only in speed stable region(Generally substantially at the uniform velocity The region of traveling), such as two station interludes, which are delivered, does not just have the problem of F.F. or hangover.
Another is LED array light beam, and the vertical LED array light beam of a rule, each light beam are installed on tunnel inner wall It is highly nearly 1 meter, nearly 600 LED are dispersed with above as a row pixel, and about 1.2 meters are spaced between two photophores.When train is quiet When only, the luminous point of a variety of colors on every light beam is can only see, when train is quickly moved, is utilized " persistence of vision " Principle can form dynamic picture.Sense the travel speed of train in real time using synchronous inductor, train by when, together Walk the glow frequency of inductor respective drive LED array light beam.Train speed is slower, and luminous frequency is higher, train speed Faster, then glow frequency is lower.Like this by the micro- distinguishing picture of stroboscopic, colored walking advertisement picture is just presented on passenger In front.
In addition, occur in that a kind of auto-stereo display system for subway tunnel now, such as State Intellectual Property Office in On April 23rd, 2014, disclose a Publication No. CN102213836B, a kind of entitled " freely standing for subway tunnel The patent of invention of body display system ", it shows that the LED light post of system is made up of multiple row LED and slit grating, and the two cooperation can Passenger is set to see stereo-picture in the case of without wearing glasses.When a slit grating is placed in before LED light post so that head is moved When dynamic, each eye can only see a row LED through slit, and eyes see adjacent column LED.The placement of slit grating can cause The width of one row LED illuminated areas is just equal to the double interocular distances of observer.When train driving passes through LED light post, on light beam Each LED will form a scan line in the passenger visual field.It is assumed that only one of which light beam in the passenger visual field, then a LED light post The scanning process of a two field picture can be completed.When LED flashes luminous according to certain pel array, and it is sufficiently high to scan frame per second When, passenger is it is seen that steady and audible still image or animation sequence.
