August Issue - Low Cost Powerful Hybrid Edge Controllers move control and data to the edge while still making both available to the cloud enabling self learning at the device and/or cloud or a hybrid of both.
decades in the building automation industry have made it crystal clear
are always moving
towards or away from centralization and I love this month's theme that
sees us moving in both direction at the same time. This is
because the success of our industry and all other industries is
embedded in the balance of cloud, edge and self learning devices.
have this evolutionary article from Alper and Therese: Data Flow
Will Mirror Air Flow in the Era of Hybrid Edge Controllers
It dawned on me that this is not just true for air but all building systems processes. Chilled water, hot water, demand response, integration of renewables, etc, everything. And that the same data may flow differently for different processes. This is part of the exciting message all self learned from haystack tagging.
You need to read this article to grasp the significance of this change; here are some quotes from article.
As Hybrid Devices enter the market, the near future will be a transition time. Two characteristics of newer controls architectures are that:
The on site PC supervisor is becoming a thing of the past. Now, AHU controllers are more likely communicating to a cloud-hosted BMS via secured Ethernet connections.
Customers are demanding that data be freed from walled gardens protected by proprietary protocols. More and more, controls designers can count on data interoperability from their equipment through full implementations of BACnet or other industry standards.
The biggest change yet, however, will be the introduction of Hybrid Controllers. These will have the full stack of resources needed to host applications for graphics, trending, alarming, control logic and advanced analytics. To a large part, they will eliminate the need for a conventional Global Controller. VAVs will communicate directly with their own Hybrid Controllers.
Future of Building Automation from Alper,
"the future" appears to be now, comes the base of this thought;
Pure object oriented programming for Building Controls
Since every object is a real life device, programming methodologies will completely change. Every equipment manufacturer will store and build essential algorithms into their devices which will give them an edge over their competitors. For example, a VFD manufacturer will essentially create algorithms that will optimize their PID loops inside their equipment. Damper actuators will have more optimized PID loops based on their communication skills to the cloud.
March of this year, this article set the scene; Energy
Analytics Controllers Edge
devices now have the intelligence and data storage they need for local
analytics and machine decision-making. They’ll soon be the thing that
the rest of the BAS universe revolves around. - Alper Üzmezler, BASSG
Lots of very well read articles last month about the power of the edge for control as well a data storage and self learning.
