Data consistency control method applied to railway signal centralized monitoring system

A centralized railway signal monitoring system, comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor to store instructions, which when executed by the at least one processor, cause the centralized railway signal monitoring system to:
• acquire, by a center of the centralized railway signal monitoring system, all data in a target time interval locally;
• encode, by the center, all the acquired data according to one or more types of data to generate a first data consistency identifier;
• send, by the center to a station, a data consistency detection command;
• inquire, by the station, all the data in the target time interval locally upon receiving the data consistency detection command and encode, by the station, the data to generate a second data consistency identifier,
• send, by the station to the center, the second data consistency identifier;
• compare, by the center, the first data consistency identifier with the second data consistency identifier;
• and
• finish a data consistency control in response to that the first data consistency identifier and the second data consistency identifier that are compared are consistent.
