Abstract: Processing system for standardization and abstraction of registers measured by measuring devices (1), which comprise processing means of measured registers (5) received for generating processed registers (5a) storable in a storage database (6) of processed registers, characteristics schemes (7a) of separate models of measuring device (1), which comprise at least one module (9) and at least one submodule (10) assigned to the said module (9) on the basis of its functioning mode (17a), each module (9) being allotted to at least one memory position of a measuring device model (1), associated with a single measuring point and assigned to at least one category map (8a) in which a submodule (10) is related to a category variable, with assignment tables (16) of category variables, mapping means (11) with assignment means (12) and transformation means (13) provided for transforming values of each measured register (1a) into values of processed registers (5a), expressed in the pre-established equivalent unit of measure
