Abstract

A building management system (BMS) includes building equipment located within a building space and a controller that receives input from the building equipment and provides a control signal to the building equipment. A floorplan geolocator receives a map providing geolocation data and overlays a building floorplan onto the map. A space geolocator receives an input defining a location of the building space relative to the floorplan and determines a geolocation of the building space using the geolocation data. A equipment geolocator receives an input defining a location of the building equipment relative to the floorplan and determines a geolocation of the building equipment using the geolocation data. A parent space detector uses geometric heuristics and the geolocations of the building space and the building equipment to identify a spatial relationship between the building space and the building equipment. The controller uses the spatial relationship to generate the control signal.

Claims

building equipment located within a building space;

a controller that receives input from the building equipment and provides a control signal to the building equipment;

an equipment geolocator that receives a second input defining a location of the building equipment relative to the floorplan and determines a geolocation of the building equipment using the geolocation data; and

a parent space detector that uses geometric heuristics and the geolocations of the building space and the building equipment to identify a spatial relationship between the building space and the building equipment;

wherein the controller uses the spatial relationship between the building space and the building equipment to generate the control signal provided to the building equipment.

2. The building management system of claim 1, wherein:

the floorplan geolocator uses the geolocation data provided by the map to determine a geolocation of the floorplan;

the space geolocator uses the geolocation of the floorplan and the location of the building space relative to the floorplan to determine the geolocation of the building space; and

the equipment geolocator uses the geolocation of the floorplan and the location of the building equipment relative to the floorplan to determine the geolocation of the building equipment.

3. The building management system of claim 1, wherein:

the space geolocator generates and provides a graphical user interface that displays the floorplan overlaid onto the map; and

the first input defining the location of the building space relative to the floorplan comprises a user input received via the graphical user interface.

4. The building management system of claim 1, wherein the first input defining the location of the building space relative to the floorplan comprises a user drawing a border of the building space onto the floorplan via a graphical user interface.

5. The building management system of claim 1, wherein:

the equipment geolocator generates and provides a graphical user interface that displays the floorplan overlaid onto the map; and

the second input defining the location of the building equipment relative to the floorplan comprises a user input received via the graphical user interface.

6. The building management system of claim 1, wherein the second input defining the location of the building equipment relative to the floorplan comprises a user placing an icon representing the building equipment onto the floorplan via a graphical user interface.

7. The building management system of claim 1, wherein the parent space detector identifies a parent space for the building equipment, wherein identifying the parent space for the building equipment comprises:

identifying a smallest existing building space that contains the building equipment; and

setting the identified building space as the parent space for the building equipment.

8. The building management system of claim 1, wherein the parent space detector identifies a parent space for the building space, wherein identifying the parent space for the building space comprises:

determining an area of the building space;

determining a location of a centroid of the building space;

identifying a smallest existing building space that contains the centroid and has an area larger than the area of the building space; and

setting the identified building space as the parent space for the building space.

9. The building management system of claim 1, further comprising an alarm manager that generates and provides a graphical user interface for viewing and managing alarms in the building management system;

wherein the alarm manager receives a user input via the graphical user interface, the user input comprising a desired control action for the building space without identifying the building equipment;

wherein the controller uses the spatial relationship between the building space and the building equipment to identify the building equipment and generates the control signal for the building equipment to effect the desired control action.

10. A method for establishing relationships between building spaces and building equipment in a building management system, the method comprising:

generating and providing a control signal from a controller of the building management system to building equipment located within a building space;

overlaying a building floorplan onto a map providing geolocation data;

receiving a first input defining a location of the building space relative to the floorplan and a second input defining a location of the building equipment relative to the floorplan;

determining a geolocation of the building space and a geolocation of the building equipment using the geolocation data; and

identifying a spatial relationship between the building space and the building equipment using geometric heuristics and the geolocations of the building space and the building equipment;

wherein the controller uses the spatial relationship between the building space and the building equipment to generate the control signal provided to the building equipment.

11. The method of claim 10, further comprising:

determining a geolocation of the floorplan using the geolocation data provided by the map;
