Digital Twins - A Boon To Internet of Things
DIGITAL TWINS
Digital twins refer to computerized companions of physical
assets that can be used for various purposes. Digital twins
use data from sensors
installed on physical objects to represent their near real-time
status, working condition or position.
One example of digital twins can be the use of 3D
modeling to create a digital companion for the physical
object.[1][2][3]
It can be used to view the status of the actual physical object,
which provides a way to project physical objects into the digital
world.[4]
For example, when sensors collect data from a connected device, the
sensor data can be used to update a "digital twin" copy of
the device's state in real time. The term "device shadow"
is also used for the concept of a digital twin.[5]
The digital twin is meant to be an up-to-date and accurate copy of
the physical object's properties and states, including shape,
position, gesture, status and motion.[6]
In another context, Digital
twin can be also used for monitoring,
diagnostics
and prognostics.
In this field, sensory data is sufficient for building digital twins.
These models help to improve the outcome of prognostics by using and
archiving
historical information of physical assets and perform comparison
between fleet of
geographically distributed machines.[7][8][9]
Therefore, complex prognostics
and Intelligent
Maintenance System platforms can leverage the use of digital
twins in finding the root cause of issues and improve
productivity.[10][11]
