Data checking method applied to area controller

The invention relates to a data checking method applied to an area controller, and belongs to the field of train control. According to the method, all related engineering data of the regional controller can be checked, and the checking algorithm comprises six different types of sub-algorithms which participate in checking in sequence; the method comprises an inter-array member table checking algorithm, an inter-device attribute table checking algorithm, a data member link relation checking algorithm based on LINK, a turnout axle counting section checking logic algorithm and a field checking algorithm. And after each check algorithm passes the check, a continuous execution mark can be set, the mark is used as the execution permission of the next algorithm, and if the check of one algorithm fails, the operation is not continued. When all the checking algorithms pass the checking, it can be judged that all the engineering data are checked successfully. The working efficiency of data modification of data configur
