Sensor measurement verification in quasi real-time

Abstract:

A method and system to perform the verification of measures done by a sensor in quasi real-time. The sensor verification may be implemented at two different levels--a functionality level and a measurement level. At the functionality level, a consistency check of information from different variables may be processed at sensor level depending on the functionality of the physical system being measured. At the measurement level, diagnostics may be performed of the circuits present in the measurement path by specific circuitry and at suitable instants of time to guarantee a Fault Tolerant Time Interval while minimizing sample loss. This may be achieved, at least in part, by increasing the measuring sample rate.
