Abstract

The invention relates to a redundancy control system for vehicle-mounted passenger information. The system comprises at least one first control system, an analog bus, a plurality of second control systems and a digital bus. Each first control system comprises a first host and a first switch, the first host is connected with the first switch, and the first host is set to send a signal; each first host is connected with the analog bus, each second control system comprises a second host, a second switch and a transparent display vehicle window, the second host is connected with the analog bus, the second host is connected with the second switch, and the transparent display vehicle window is connected with the second switch and the analog bus. The first switch is connected with the adjacent second switch and the two adjacent second switches through the digital bus, and the second host can receive signals from the analog bus and the digital bus at the same time, so that network bus redundancy is formed between the analog bus and the digital bus, the reliability of the system is improved, and the failure rate of the PIS system is reduced.

Description

technical field [0001] The present application relates to a vehicle passenger information system, in particular to a redundant control system of vehicle passenger information. Background technique [0002] With the continuous advancement of rail transit communication signal technology and computer information technology, the train passenger information (PIS) system, as a key service system to improve passenger experience and improve vehicle operation efficiency, has become the standard configuration of rail transit trains. It is getting more and more attention from operators, integrators and passengers. The existing on-board PIS system for trains mainly includes three subsystems: train broadcasting, train video entertainment and train video monitoring, providing passengers with real-time and multi-service service information, including broadcast voice station announcement service, subway line information display service, advertisement and entertainment video Broadcasting se...
