ARCHITECTURE LAYER INTERFACING DEVICES AND APPLICATIONS

摘要

An interface layer and method is provided that permits applications (10), without modification, to operate with any type of meter (30). The interface (20) comprises an abstraction layer and library or repository of description s specific to each meter type. The abstraction layer provides the capability t o communicate with any meter (30) through a variety of applications (10). Upon receiving an application request, the abstraction layer retrieves the description for the particular meter type from the repository and processes the request. In this manner, only one data representation is needed for applications to communicate with a wide variety of meters (30).
