Application framework for constructing building automation systems

摘要

The building automation application framework defines an object- oriented class hierarchy in which a standard object superclass defines a plurality of different standard objects that may be assembled by a system designer into larger and more complex building automation systems. The standard objects include a view component that handles implementation details of displaying that object's contents on a standardized or generic user interface browser. The standard object also includes a command component that identifies to other objects what methods may be invoked by that object, thereby relieving the system developer from attending to this programming detail. The application framework defines a building automation model that is application- centric, as opposed to device- centric. Applications are constructed by interconnecting standard objects, assemblies formed from standard objects, and other application objects.
