Abstract

Described herein are systems and methods for configuring a BMS. In general terms, the present technology is focused on approaches for arranging and modeling building information data, particularly in terms of equipment categories and relationships between pieces of equipment, for example in the context of an HVAC system. This is advantageous in the sense that the likes of visualization, application creation, and reporting are able to be significantly streamlined. Various embodiments make use of an “equipment model”, being a model which defines items for each piece of equipment in a building system based on predefined standards, thus allowing for predictable descriptions (for example in terms of data points and relationships). Some embodiments combine this with a facility model, which describes a building in spatial terms.

Claims

1. A method for configuring a building management system (BMS), the method including;

storing a repository of equipment model templates in a memory, wherein each template defines a data organizational framework that is configured to describe a category of equipment in a building system, one or more data points associated with a piece of equipment belonging to that category, the roles of those data points, and relationships with one or more further pieces of equipment for which equipment model templates are defined;

a user defining a plurality of equipment model items using the repository of equipment model templates via a user interface that is in operative communication with the memory, such that each equipment model item describes a specific physically installed piece of mechanical equipment in terms of data as required by the template, wherein for a given physical installed piece of mechanical equipment, the defining includes;

(i) selecting, from the repository of equipment model templates via the user interface, the category of equipment that describes the physical installed piece of mechanical equipment; and

(ii) for each of the one or more data points associated with the selected category of equipment, associating via the user interface the data point with a physical installed control level item associated with the physical installed piece of mechanical equipment, being a control level item from which data is received by the BMS, such that the BMS is configured to attribute data receive from that control level item with that data point;

constructing an equipment model including the defined equipment model items, wherein the equipment model provides for automated visualization of the equipment model items defined to represent physical installed pieces of mechanical equipment in terms of location and relationships; and

using the equipment model to automatically visualize the equipment model items defined to represent physical installed pieces of mechanical equipment in terms of location and relationships on a display.

2. A method according to claim 1 wherein the relationships with the one or more further pieces of equipment are defined in terms of reliance relationships and containment relationships.

3. A method according to claim 1 wherein, for at least one category of equipment, the template is configured to additionally describe a serviced area, wherein the serviced area is additionally defined in a facility model that describes physical locations within one or more buildings in respect of which the BMS is configured to operate.

4. A method according to claim 1 wherein the equipment model templates include a plurality of HVAC templates for respectively describing categories of equipment in an HVAC system.

5. A method according to claim 4 wherein for at least one category of equipment in the HVAC system, the template is configured to additionally describe a region uniquely serviced by the piece of equipment.

6. A building management system (BMS) comprising:

a physical memory for storing a repository of non-transitory data that is indicative of plurality of equipment model items, these equipment model items based on predetermined equipment model templates, such that each equipment model item describes a specific piece of equipment in terms of a category of equipment selected from a set of available predefined categories of equipment, one or more data points associated with a piece of equipment belonging to that category, the roles of those data points, and relationships with one or more further pieces of equipment;

a user interface that accepts input from a user to define each equipment model item to describe a specific physical installed piece of mechanical equipment in terms of data as required by one of the predetermined equipment model templates, wherein for a given physical installed piece of mechanical equipment, the user interface is configured to accept input to;

(i) select, from the repository of equipment model templates, a category of equipment which describes the physical installed piece of mechanical equipment; and

(ii) for each of the one or more data points associated with the selected category of equipment, associate the data point with a physical installed control level item associated with the physical installed piece of mechanical equipment, being a control level item from which data is received by the BMS, such that the BMS is configured to attribute data receive from that control level item with that data point; and

a visualization module including a physical display for automated visualization of the equipment model items defined to represent physical installed pieces of mechanical equipment in terms of location and relationships.

7. A BMS system according to claim 6 wherein the relationships with the one or more further pieces of equipment are defined in terms of reliance relationships and containment relationships.

8. A BMS system according to claim 6 wherein, for at least one category of equipment, the template is configured to additionally describe a serviced area, wherein the serviced area is additionally defined in a facility model for the BMS, wherein the facility model that describes physical locations within one or more buildings in respect of which the BMS is configured to operate.

9. A BMS system according to claim 6 wherein the equipment model templates include a plurality of HVAC templates for respectively describing categories of equipment in an HVAC system.

10. A BMS system according to claim 9 wherein for at least one category of equipment in the HVAC system, the template is configured to additionally describe a region uniquely serviced by the piece of equipment.

14. A BMS system according to claim 6 comprising:

data indicative of a plurality of facility model items which respectively describe physical locations within a building environment in terms of a category of location, and relationships with other locations, wherein a category of facility model items describe locations uniquely serviced by respective pieces of HVAC equipment; and

data indicative of plurality of equipment model items, each equipment model item describing a specific piece of HVAC equipment in terms of a category of equipment selected from a set of available predefined categories of equipment, one or more data points associated with that piece of equipment, the roles of those data points, and relationships with one or more further pieces of equipment, wherein for at least one category of equipment the equipment model items include data indicative of a location uniquely serviced by that piece of equipment;

such that the facility model items and equipment model items are linked by the locations uniquely serviced by respective pieces of HVAC equipment.

15. A BMS system according to claim 14 wherein the visualization module is configured to automatically visualize the HVAC system on the display based on information in the facility model items and equipment model items.

16. A computer system according to claim 14 wherein:

a facility model is configured to provide a graphical representation of the facility model items via a tree structure, and an equipment model is configured to provide a graphical representation of the equipment model items via a tree structure, such that the facility model and equipment model being linked by the locations uniquely serviced by respective pieces of HVAC equipment to provide a graphical representation on the display of the facility model items and equipment model items via a common tree structure.
