Along with the high-speed development of international aviation and rail transit, the rail transit and an airport Ground Traffic Center (GTC) are mutually fused, so that the demand that the specific gravity of aviation travel passengers and rail transit transfer is continuously increased is met, and the travel efficiency and experience of the passengers are greatly improved. In general, in order to enlarge the abdominal area of aviation passenger sources at airports, rail transit stations are often underground stations. According to the regulations of the railway technical regulations (section of high speed railways) provision is made: the passing speed of the train is greater than 80km/h, if necessary, safety protection facilities are arranged at the position 1200mm away from the edge of the platform, and the safety protection facilities such as shielding doors, safety doors and the like are arranged when the train passes over 200 km/h. In order to reduce wind pressure and wind noise generated by the entrance and exit of a high-speed train, a top-driven full-height platform door is often selected by an underground station, and further, the problem of self-adaptive alignment of the platform door and a vehicle door under the conditions of different marshalling and different vehicle types of motor train units is considered, and the problem that the self-adaptive right-opposite door opening can be solved by arranging a sliding door on the whole side of the platform door and adopting a double-staggered-folded door opening mode.

In the rail transit field, in order to improve passenger's waiting and riding experience, the passenger in the subway platform can see the fixed advertising lamp house opposite to the shield door when waiting for the train, and fixed lamp house advertisement becomes the mainstream of present subway shield door advertisement, but fixed lamp house advertisement exists because of the unable attraction passenger of static picture and advertising effect not good factor, can't realize functions such as more dynamic video broadcast, passenger's interdynamic, vehicle platform information release.

For example, the utility model patent with publication number CN205069072U proposes an interactive projection imaging device for a subway glass shielding door, which comprises a central control system, a signal sensing system, an information transmission system, a display system, a sound system, an interactive system and an intelligent sensing system, wherein: the central control system is connected with other 6 systems.
