Now try this out without touching the real thing: an alternative factory layout, a new jet engine or a hospital workflow. Do the experiment on a virtual copy, watch what’s broken, fix it and then actually construct the experiment. Digital twin technology will transform the way modern industries design, monitor and maintain what they design, and that is the idea now.
What is a Digital Twin?
A digital twin is a virtual copy of something that remains connected to the actual object, system, or process in the real world with real-time data. It’s more than just a 3D drawing. The drawing does not change once it is created, but the digital twin will continuously update. If a real machine gets hot, slows down, or vibrates, so does its twin almost immediately.
The idea originated from NASA’s research on spacecraft simulation, where engineers would have to troubleshoot the vehicle without having to go to it. The concept was originally conceived by researcher Michael Grieves in the early 2000s and the term “digital twin” was popularized by NASA’s John Vickers.
How Does Digital Twin Technology Work?
The digital twin technology will drive this iterative cycle of sensing, modelling, analysing and acting.
- Collect real-world data with sensors
On the physical asset are IoT sensors that measure aspects such as temperature, pressure, speed, vibration, energy usage, etc.
2. Data is transmitted to a Platform
The readings go over the network to a cloud or edge computing system for storage and processing.
3. A Virtual Model is Created
The digital model is created by engineers based on design files, CAD files and physics-based simulation.
4. The Twin Syncs in Real Time
The model is constantly updated with live sensor data, which means the twin is always current with the asset’s condition.
5. Analytics and AI Find Insights
The twin is used to analyze software and identify signatures that could signal potential failures, and to perform “what if” testing in a benign environment.
6. Decisions Back to the Real World
The information is applied to make changes in operations, to plan the maintenance, or to design the next one. Then the loop is repeated.
Types of Digital Twins
Not all twins are created equal.
- Component twin: One component of a bearing or valve, etc.
- A full wind turbine, or other asset, is known as an asset twin.
- System twin: A combination of assets operating as a system, e.g., a production line.
- Process twin: a whole process, like a supply chain or a traffic network of a city.
Real-World Uses
- Faster forecasting of anticipated breakdown times in manufacturing: Factories predict ahead of time and avoid expensive downtime.
- In healthcare, virtual organs and patient information will be used to plan treatments more precisely, with researchers and doctors studying them.
- Planners model traffic, power, and water systems in advance of real changes in smart cities.
- Time and money are saved by engineers testing for safety and performance virtually in the Aerospace and Automotive industry.
- Real estate and retail: Companies simulate building operation and store design to avoid costly mistakes.Real estate and retail: Companies simulate building operation and store design to avoid costly mistakes.
How Hologram Technology Makes Digital Twins Easier to Understand?
A digital twin generates a ton of data, and if you’re looking at a flat, data-heavy dashboard, it may be difficult to read. Many companies, therefore, couple twins with Hologram Technology, which creates 3D images that seem to float in space. Teams can navigate the virtual machine and rotate it to view it from any angle, rather than reading charts.
The Holographic Projector can display an actual twin of a turbine, a building or a human heart in front of an entire room. Having complex data on display that can be viewed, discussed, and understood in a group can speed up decisions in meetings and in training sessions.
A Hologram Wall extends it for exhibitions, showrooms and corporate events. It is a large display surface with a digital twin of a product displayed in 3D with live performance data that is side by side. The user can learn how something works without having to physically handle a model of it in the room.
One disclaimer: a fair number of displays marketed as holographic aren’t quite using a laser to produce the illusion of 3D; instead, they’re using a transparency screen, an LED fan or a projection effect. They remain a great 3D experience and they’re much more useful for business today.
Key Benefits of Digital Twin Technology
- Predictive maintenance: Issues are resolved in advance of failure.
- Lower costs: Virtual testing will lessen the need for costly prototypes.
- More innovation in less time: More teams can test out numerous design concepts in a relatively short amount of time.
- Better decisions: Real-time visibility supplants guesswork.
- Better safety: Risky situations can be tested without any actual risk.
The Future of Digital Twins
With the advent of the popularization of sensors and the advancement of AI, digital twins will be utilized in daily business beyond the realm of large industry. With holographic projectors and hologram walls becoming cheaper, people will interact with the twins as they would do with a phone today. A world where everything, from a single machine to an entire city, has a virtual, alive counterpart.
Final Words
The digital twin technology is making a splash between the physical and digital world, and it saves money, reduces risk, and generates new ideas. Combined with the immersive Hologram Technology, it converts complex data into what can actually be seen and understood. If you haven’t yet explored it, do so on a small scale and learn from one project and take it from there.
