Automation is now very important in tunneling. In a tunnel boring machine, automation means using smart systems. These systems let the TBM work with little help from people. They use data from sensors and watch things in real time to make choices. The main ideas are:
NHI uses these ideas in its TBMs. This makes tunneling better and faster.
Digital control systems are the main part of automated TBMs. These systems gather and use data from many places. They get data from sensors in the machine and in the tunnel. The main subsystems are:
| Key Subsystems | Description |
|---|---|
| Modeling | Shows how the TBM might work in different cases. |
