BUILDING AUTOMATION SYSTEMS WITH AUTOMATIC METADATA TAGGING AND MANAGEMENT

1 . A method for managing tagged entities by de-linking one or more tags in a building automation system (BAS), the method comprising:

identifying, by a processing circuit, entities associated with a station in response to receiving an indication to manage entities;

determining, by the processing circuit, a tag dictionary input wherein the tag dictionary input corresponds to selection of one or all tag dictionaries associated with the station;

determining, by the processing circuit, one or more tags originating from the selected tag dictionary for each of the entities; and

managing, by the processing circuit, the entities by:

electing one or more entities wherein elected entities refer to entities from which one or more tags is to be de-linked;

selectively de-linking, one or more tags from the elected entities wherein removal of tags correspond to removal of tags originating from the selected tag dictionary; and

retaining tags, associated with non-selected one or more tag dictionaries and non-elected entities.

2 . The method of claim 1 , wherein the processing circuit is enabled to select a pre-defined default tag dictionary associated with the station as tag dictionary input.

3 . The method of claim 1 , wherein the processing circuit is enabled to receive the tag dictionary input from a user interface when the station is not associated with a pre-defined default tag dictionary.

4 . The method of claim 1 , wherein the tags determined from the selected tag dictionary are direct tags.

5 . The method of claim 1 , wherein a user interface produces the indication to manage de-linking of one or more tags of tagged entities in the building management system (BMS).

6 . The method of claim 1 , wherein the entity comprises one of a space, a piece of equipment, a sensor, a device, or a point.

7 . The method of claim 1 , wherein the processing circuit is enabled to identify entities associated with the station in a system library in response to receiving the indication to manage entities, wherein the system library comprises a plurality of relationships between a plurality of tags and a plurality of entities.

8 . A method for managing tagging of entities in a building automation system (BAS) comprises:

receiving, by a processing circuit, an indication to manage tagging of entities;

identifying, by the processing circuit, the entities in a system library wherein the system library comprises a plurality of relationships between a plurality of tags and a plurality of entities;

determining, by the processing circuit, one or more tags associated with the entities based on the system library;

identifying, by the processing circuit, one or more entities to which one or more tags is to be added;

determining, by the processing circuit, an entity type of the identified entity;

determining, by the processing circuit, a tagging mechanism for the identified entity to which tag is to be added; and

managing, by the processing circuit, tagging of the entities by adding one or more tags based on the determined tagging mechanism.

9 . The method of claim 8 , wherein the tagging mechanism for tagging the identified entity type is determined, by the processing circuit, based on a pre-defined tagging mechanism associated with the entity type.

10 . The method of claim 8 , wherein the tagging mechanism for tagging the identified entity is determined based on an input defining election of the tagging mechanism for adding one or more tags.

11 . The method of claim 8 , wherein a user interface produces the indication to manage tagging of one or more entities in the building automation system (BAS).

12 . The method of claim 8 , wherein the entity comprises one of a space, a piece of equipment, a sensor, a device, or a point.

13 . A building automation system comprising:

a system library comprising a plurality of relationships between a plurality of tags and a plurality of entities; and

a computing system coupled to the system library, the computing system configured to manage entities within a station, wherein managing entities correspond to one of:

selective de-linking of one or more tags corresponding to one or more tagged entities; and

tagging of one or more entities by determining a tagging mechanism for adding one or more tags to one or more entities.

14 . The building automation system of claim 13 , wherein the process of selectively de-linking tags corresponding to tagged entities comprises:

identifying entities associated with a station in response to receiving an indication to manage entities;

determining a tag dictionary input to enable selection of one or all tag dictionaries associated with a station;

determining the tags originating from the selected tag dictionary for each of the entities, and subsequently recognizing the entities having tags originating from the selected tag dictionary; and

indicating one or more recognized entities from which one or more tags originating from the selected tag dictionary is to be de-linked.

15 . The building automation system (BAS) of claim 13 , wherein the tags being de-linked are direct tags.

16 . The building automation system (BAS) of claim 14 , wherein the computing system is configured to identify entities associated with the station in a system library in response to receiving the indication to manage entities.

17 . The building automation system (BAS) of claim 13 , wherein the process of managing tagging of one or more entities comprises:

identifying the entities in a system library wherein the system library comprises a plurality of relationships between the plurality of tags and the plurality of entities;

determining one or more tags associated with the entities based on the system library;

identifying, one or more entities to which one or more tags is to be added;

determining, an entity type of the identified entity;

determining, the tagging mechanism for the identified entity to which tag is to be added; and

adding, one or more tags to the identified entity based on the determined tagging mechanism.

18 . The building automation system (BAS) of claim 17 , wherein the tagging mechanism is determined based on an input defining election of the tagging mechanism.

19 . The building automation system (BAS) of claim 17 , wherein the tagging mechanism is a pre-defined tagging mechanism corresponding to the entity type.

20 . The building automation system (BAS) of claim 17 , wherein determining one or more tags associated with the entities is performed to avoid addition of duplicate tags.

21 . The building automation system (BAS) of claim 13 , wherein the entity comprises one of a space, a piece of equipment, a sensor, a device, or a point.
