METHOD FOR CHECKING ERROR OF FULL ELECTRONIC SWITCH BY COMPARING RELATION OF DATA FILE

摘要

PURPOSE: A method for checking error of full electronic switch by comparing relation of data file is provided to prevent an error caused by the discordance of respective data by checking relation of file used in processor which is now operating and relation of file stored at disc according to the request of operator, periodically or beforehand. CONSTITUTION: A method for checking error of full electronic switch by comparing relation of data file comprises the steps of: judging whether it get to an error checking time set by operator; reading relation of data file corresponding to the subject processor of check from disc when it get to the error checking time or performance request by direct order of operator is inputted; first comparing a relation header of read relation with a relation header stored at processor memory; second comparing relation data is read after a first comparing step with the relation header stored at processor memory; and judging as normal when a result of second comparing step accords each other and judging as error when the result of second comparing step discords each other.
