How Digital Twins Work
Understanding the components and processes behind digital twins is key to unlocking their full potential.
Components of a Digital Twin System
- Physical Entity: The actual device, machine, or system in the real world.
- Digital Replica: The virtual model designed to accurately reflect the physical entity.
- Data Connections: Continuous data streams from sensors and IoT devices linking the physical and digital versions.
Data Collection and Integration
Sensors embedded in physical assets gather real-time information such as temperature, pressure, and operational status. IoT devices then transmit this data to the digital twin platform for analysis and updates.
