What is Digital Twin Technology?

A digital twin is a digital representation or replica of any asset in the real world.

Here is the list of machine or human assets we can monitor in real-time.

  • A machine component such as a motor.
  • A complete product such as a car, bicycle, or turbine.
  • Manufacturing process
  • Systems such as a human body

We can use digital twins to monitor and replicate the entire life cycle of assets and predict asset behavior in the future. For example, Engineers can predict future failures and improve a machine (pump, turbine) design using its digital model.

Following technologies are driving the growth of the digital twin technology.

  1. Virtual Reality
  2. Augmented and Mixed Reality
  3. Internet of things
  4. Big Data
  5. Machine Monitoring
  6. Cloud Computing
  7. Machine Learning

How does Digital Twin Work?

Digital Twin System works by connecting physical machines with the virtual world by getting input from asset sensors. Sensors send real-time data to a connected device or cloud. 

We can make assets virtual copies from the real-time product data in the cloud or edge computing device. A asset virtual-copy is its mathematical model.

We can analyze and simulate the assets in a virtual copy. In this way, we can simulate assets performance in actual working conditions.

Digital twin works by connecting real and virtual worlds by collecting real time sensor data using IoT connected sensors.
Working of Digital Twin

The above image shows the working of a vehicle digital twin. In this, the car sends real-time sensor data to the cloud. The sensor data create a digital model or digital twin for the vehicle in the cloud. This car’s digital twin behaves similar to the actual vehicle.

In this way, we can use the digital twin to analyze the vehicle performance on various parameters by running simulations in the virtual world. Product designers can build more understanding of the existing products and improve new products from the data from the digital twin.
