Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0026] The multimedia projection imaging process on the subway glass screen door among the present invention mainly is:
[0027] 1) When the subway PIS incoming signal is received or the incoming sensor group of the train position signal system is triggered, it indicates that the train is about to enter the station, and the central control system controls 4 to turn on the transparent state of the dimming glass (power on), turn off the display system, and turn off the interactive function , the sound is turned off or a prompt to guide customers is issued, and the screen door returns to its original state;
[0028] 2) When the subway PIS departure signal or the train position signal system exit sensor group is triggered and the station sensor senses that there is no train at the station, it indicates that the train has left the station, and the c...
