• Autonomous Inspection Systems:
– Periodic scanning and defect detection using AI algorithms
– Remote data transmission for real-time analysis
Detailed Explanation
Autonomous inspection systems utilize AI algorithms to perform periodic scans of the tunnel's structural integrity. This scanning process automatically checks for defects, allowing for proactive maintenance. The data collected is transmitted remotely, which means engineers and monitoring teams can analyze the tunnel's condition in real-time without having to physically inspect the site.
Examples & Analogies
Consider an automated home alarm system that not only detects intruders but also sends alerts with video footage to your phone. Just like that system keeps you informed of your home’s security status, autonomous inspection systems keep engineers updated about the health of a tunnel without requiring them to be onsite.
