The passenger information system（PIS） is an important facility for providing services on the train. It mainly realizes the two-way transmission of car-ground information, and after decoding by the on-board playback controller, the relevant information issued by the control center is played in real time on all LCD displays of the train. information. At the same time, the video surveillance images in the train are transmitted to the control center.
