Gas meter data validation

摘要

Gas meter data validation for a Meter Data Management (MDM) system (100) including a communications network connecting gas data downloading device(s) (110) receiving gas meter data including (201) corrected gas volume data (CGVD) and state variable(s) data from primary gas meter(s) (105 and 106) to the system, and a server (140) implementing gas data validation (GDV) software (140b). The GDV software performs (202) data validation checks on the gas meter data including the CGVD to identify erroneous CGVD, and if a data validation check fails, performs (203) a root cause analysis to diagnose a root cause involved in the erroneous CGVD using the data validation check and additional information regarding the communications network and primary gas meter, and performs (204) error resolution depending on the root cause during the time interval including (i) calculating a revised CGVD after refetching uncorrected GVD and the state variable data or (ii) estimating the state variable data and calculating the revised CGVD therefrom.
