[0028] Adaptive frequency conversion animation device in subway tunnel

[0029] The structure of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] Such as figure 1 figure 2 As shown, in the subway or train tunnel wall, along the direction of travel, a series of continuous animation images are set at positions where the passengers in the compartment can easily see through the windows. The image width (even spacing) should not be too wide (for example, it can be set to 1000mm), and the height should be appropriate (but you don’t have to stick to the aspect ratio, that is, it is allowed to exceed 1000mm of the set width to increase the viewing area).

[0031] There is no lighting on the screen, especially no light box. This can not only save investment, but also save energy, and will not interfere with train running.

[0032] The picture is fixed to the front of the tunnel wall in a simple way. As long as...

Abstract

The invention discloses an adaptive variable frequency animation device in a metro tunnel. The device comprises animated images (1), strobe light sources (2) and a train speed synchronous controller, and is characterized in that: the animated images (1) are a series of progressively evolved plane images which are arranged at positions where passengers in carriages conveniently view the animated images through train windows along a train advancing direction in a metro or train tunnel wall at an equal interval; the strobe light sources (2) are arranged at proper positions on the outer surfaces of the carriages of a train and triggered by triggering signals of the train speed synchronous controller, and can irradiate the animated images (1) by facing the animated images; and the triggering frequency of the train speed synchronous controller over the strobe light sources (2) is required to be consistent with the movement frequency of the animated images (1) relative to the advancement of the train. When the train is advanced in the metro tunnel, a vivid animation advertising effect can be achieved. The device has the advantages of small investment, remarkable effect, no strict requirements on an implementation environment, energy saving, freedom from the influence of train speed variation, high adaptability and the like, and is easy to implement.

Description

technical field [0001] The invention belongs to the technical field of advertisement display, in particular to a frequency conversion animation display device realized in a subway tunnel. Background technique [0002] As an important facility of urban transportation, the subway plays an increasingly important role in people's daily life. In Shanghai alone, more than a dozen lines have been put into use or are under construction. The total length will reach more than 400 kilometers in 2010, and it is planned to reach more than 800 kilometers by 2020. [0003] For such a large-scale facility, how to improve its environmental appearance and give full play to its advertising advantages should not be underestimated. Therefore, people have always been interested in trying to realize animation in subways or tunnels. There are also various ideas and patent applications. [0004] But looking at it all together, there seem to be a few things that are biased and overlooked: [0005...
