BACnet preparations

With the BACnet interim spring meeting just a week and a half away, it's time to make sure everything is ready to go.  Looking over my proposal, WS-068, "Elevator Monitoring in BACnet," I found a few minor editorial corrections needed (indentations and text colors), revised them and sent them off to Dave Robin, committee chair, for inclusion in tracking documents and the appropriate meeting folders.

The "companion" (or derivative) proposal, WS-093, "Elevator Structures in BACnet," should give the Application Profiles group something to think about.  Their work for so very long has been on how (and what) to model for standard building automation devices such as variable-frequency drives and VAV controllers, but this proposal presents something different:  How to group a number of objects (Lifts, Escalators, Elevator Groups and so on) into some kind of a traversable hierarchical system that could span across devices or larger entities.

(Think "City of Hong Kong" -- "Building 123 Main St" -- "Tower 5" -- "Elevator Group 3" -- Lift 2" and you might get an idea.)

It could be a fun time in the meetings week after next.

And then I'm off to Saarbrücken, Germany, for the European plugfest the week after.  

Almost ready for that too: today I registered the Alerton devices I'm bringing with the Customs and Border Protection folks, down at the King County International Airport in Seattle.  (Until this week I didn't even know we had a "King County Airport," much less an international one!)  The officials didn't seem impressed by all the advanced BACnet technology embedded in the little plastic boxes on DIN rails.  And they didn't seem like they wanted to hear about the increased comfort and lower operational costs these little boxes could give them, or what the Smart Grid would soon do for them, or... 

Oh, well.
