Point Classifier UI
The classification of points after they are linked to their respective equipment/location is done on the Point Classifier found on the DCH UI. The tool allows users to batch classify their points by using text pattern matching and assign entity properties and Units of Measure to them.
From the home page on DCH, on the left panel, go to Tools and select Point Classifier.
You can use previously created and saved classifier sets or create a new one.
Creating a new classifier set
On the Point Classifier page, swap to Create New.
Assign a name to the classifier set (New Classifier Set Name field).
Select a target data pool to execute the classification on (Data Pools field).
Press the + button on the right to create a new rule. On the left side of the table, you can declare the target points and on the right you declare the changes you wish to make on those target points on the left.
Left Hand Side (target points)
ID field is where the text pattern is declared to identify target points.
Label field is a human readable text which you can use to identify points (if the target points already have labels).
Class is the BRICK class you wish to target (if the target points already have BRICK classes assigned).
UoM allows for targeting based on Units of Measure (if the target points already have UoM declared).
Right Hand Side (desired changes to the target points)
Label field is the new human readable text which you can set for the target points.
Class is the new BRICK class you wish to assign to the target points.
UoM is to change the units of measure for the target points.
Properties is where you can declare BRICK Entity Properties for the target points.
When you are done mapping the changes to the target points, press Generate Rules. A new Results section opens at the bottom showing the pending changes for approval. If you are happy with the results, press Apply Changes to save the rules for this classifier set and apply the set to the data pool.
Order of pattern classification as described in the GENERATE_CLASSIFIERSET operation holds here.
E.g. Points with pattern "*AHU1" are classed as brick:Enable and Points with "*AHU1.Filter" are classed as brick:Status. "*AHU1" should be declared at a higher row in the CSV:
In contrast, by doing "AHU1.Filter" first, when the pattern "AHU1" is processed, the class for "AHU1.Filter" is overwritten to be brick:Enable, instead of brick:Status.
Using previously generated and saved classifier sets
On the Point Classifier page, go to the Search Saved Sets tab.
For Search Classifier Sets select the classifier set set you wish to view/edit.
In the Data Pools field select the data pool you wish to apply the set to.
Press Generate Rules to apply the changes (pending approval).
Review the results and approve the changes by pressing Apply Changes.
