The invention relates to a platform door management host and a platform door
system, which are used for
processing received vehicle door alignment and isolation management data of a vehicle door of an automatic
train monitoring subsystem, sending a vehicle door alignment and isolation request to a fault door
control unit, and sending detected fault door
control unit information to the automatic
train monitoring subsystem. The platform door alignment isolation
management system comprises a main control board, a communication board and a switching board which are arranged in a first
machine cage, and an input board and an output board which are arranged in a second
machine cage, and the first
machine cage is in communication connection with the second machine cage; the platform door management host adopts double-
system redundant
backup setting, each
system is provided with a main control board and a communication board, the number of the main control boards is the same as that of the
communication boards, and main-standby switching logic management is carried out between the double systems through a switching board. Compared with the prior art, the system has the advantages of low
failure rate and high safety and reliability through board card level redundancy.
