Title:
TRAIN CONTROL DMI DATA REDUNDANCY CONTROL METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/073221
Kind Code:
A1
Abstract:
A train control DMI data redundancy control method. A DMI simultaneously receives and processes two groups of data which are mutually in a main and backup relationship, the DMI determines the main and backup relationship on the basis of a parsed result of the data, and the DMI displays main system data. The system comprises: two main control units used for separately sending data to the DMI, the two groups of data being mutually in a main and backup relationship; and the DMI used for simultaneously receiving and processing the two groups of data which are mutually in the main and backup relationship, determining the main and backup relationship on the basis of the parsed result of the data, and displaying the main system data. The DMI simultaneously receives the data sent by the two main control units, and respectively takes the two main control units as a main system and a backup system according to two main and backup system identifiers; when the main system is abnormal, the two main and backup system identifiers change, the main system and the backup system are switched after the DMI identifies that the two main and backup system identifiers change, the content displayed by the DMI is not affected, and a switching module does not need to be configured. The structure is simple, and the switching efficiency is high. The train control DMI data redundancy control system is further disclosed.
