The application discloses a multi-battery cabin EMU cooperative safety upgrading method and
system, and belongs to the technical field of
electrochemical energy storage system operation and maintenance. The method comprises the following steps: constructing a dedicated high-
reliability management network isolated from a business network and performing hierarchical
health diagnosis; performing
cluster state sensing and parallel file distribution based on adaptive sliding window and hash check; before executing an upgrading instruction, forcibly performing business safety
interlocking inspection including
bus voltage,
cell temperature,
state of charge and
system silent window, triggering upgrading only under safe working conditions, and synchronously starting
cluster state cooperative monitoring; after upgrading is completed, automatically performing full-cluster
software version consistency check, and generating a structured audit report and an automatic fault disposal work order based on the check result. The application deeply embeds safety logic into the upgrading process, realizes cluster cooperative sensing and automatic operation and maintenance
closed loop in the upgrading process, and significantly improves the safety, reliability and operation and maintenance efficiency of large-scale
energy storage system software upgrading.
