The rail transit Passenger Information System (PIS) utilizes communication and multimedia technology and provides passengers with allround and multiscene information service systems based on a variety of display terminals. To address the drawbacks of the current rail transit Passenger Information System, such as overinvestment in hardware, low deployment and debugging efficiency, long broadcast control transmission link, and poor reliability, this paper proposes a cloud broadcast control technology architecture for the new generation Passenger Information System, which is "system into the cloud and broadcast control into the screen, " and describes in detail the technical advantages brought by the cloud playcontrol architecture through reforming the traditional audio and video transmission modes. The problem regarding picture synchronization on a multidisplay terminal was analyzed. The results show that the cloud playcontrol technology reduces the fault nodes by 50%, improves the deployment and debugging efficiency, achieves intensive construction, and can provide application support for various personalized scenarios f throughout the entire process of passenger travel from arrival to departure, which can provide reference for the subsequent construction of passenger information systems.
