摘要
A passenger information system wherein, on the basis of the concept of redundant driver cab control main units (11) in the prior art, multiple passenger compartment control main units (21, 22...) are provided in passenger compartment control main unit assemblies (2) of each car, so as to achieve redundancy of the passenger compartment control main units (21, 22...). The driver cab control main unit (11) replaces a faulty passenger compartment control main unit (21, 22...) with a passenger compartment control main unit (21, 22...) in a normal state from the same assembly, so as to avoid a standstill of an entire train network caused by the interruption of information transmissions passing through the passenger compartment control main units (21, 22...), thereby improving redundancy of the passenger information system, and ensuring normal communication between each section of the passenger information system. Also disclosed is a passenger information system control method. The method has the described advantageous effects.
