Digital Twin Models and Virtual Properties

Twin Towser

Another interesting aspect of a Digital Twin Model is the use of virtual, or calculated properties to derive additional IoT value.

While “virtual properties” don’t have a 1:1 relationship with the “telemetry properties” (sensors) I described in my previous post, that are actually sending data from a device, they’re super-valuable. The value assigned to a virtual property is typically derived from a mathematical combination of values from one or more telemetry properties and possibly other reference data. For instance, calculating miles per hour (speed) of a car is a good example of a virtual property where a combination of telemetry properties like the rotating drive shaft and magnetic sensors use simple analytics to tell you how fast you’re going.

While not always necessary, virtual properties deliver additional value and insights.
