Methods and systems for data parameter reasonability analysis

Abstract:

An example method for data parameter reasonability analysis includes receiving a source data file including a plurality of data frames having formats that are unknown, and a data frame includes a data word layout having data words concatenated together and the data words are representative of outputs from a plurality of sensors, comparing the sensor data to compatible parameter values for a type of sensor mapped to the location of the sensor data in the data word layout as for available data frame formats, generating a difference map illustrating one or more data words having sensor data incompatible with the type of sensor mapped to the location of the sensor data in the data word layout, assigning a data frame format to the plurality of data frames, determining reasonableness of the sensor data in the source data file, and providing a report as to reasonability of the sensor data.
