Brick v1.4 RC1- Modeling Sensor Equipment

[Sarah MacDougall]

Your new Terminal Unit documentation also demonstrates the use of brick:Sensor_Equipment: https://docs.brickschema.org/modeling/terminal-units.html. Does the community have a recommendation when modeling sensors in a room?

If you model sensors to be part of a piece of equipment that represents the box that sensors reside in like below, then you need to create a query to search for Points ‘IsPointOf’ EquipmentX that ‘hasLocation’ RoomX.

bldg:room1 a rec:Office ;    rdfs:label "Personal Office" ;    rec:isLocationOf bldg:sensor_box_1 .

bldg:sensor_box_1 a brick:Sensor_Equipment ;    brick:hasPoint bldg:rmat1 .

bldg:rmat1 a brick:Room_Air_Temperature_Sensor ;    brick:hasUnit unit:DEG_F ;    ref:hasExternalReference [        bacnet:object-identifier "analog-value,8" ;        bacnet:object-name "BLDG-Z410-ROOM" ;        bacnet:objectOf bldg:sample-device ;

Alternatively, if you model sensors to be Point ‘isPointOf’ RoomX, then you can create a query to directly search for points located in a room.

 

Do you recommend when modeling Sensor Equipment that you also model the Point ‘IsPointOf’ RoomX relationship? 

 

For example add this additional relationship to the relationships above :

 bldg:room1 brick:hasPoint brick:Room_Air_Temperature_Sensor .
