AI Technical Summary
Existing methods for measuring foundation pit deformation are point-based measurements that rely on benchmarks and cannot achieve fully automated monitoring, resulting in blind spots and affecting measurement accuracy.
A foundation pit monitoring system based on distributed optical fiber is adopted. By combining the optical fiber in the monitoring device with the top of the moving pole, the deformation of the foundation pit perimeter is monitored in real time. The conversion relationship between optical fiber distance and scale value is established to achieve real-time monitoring of the entire area and the entire cycle.
It has achieved fully automated monitoring of foundation pit deformation, improved measurement accuracy, and can detect dangerous situations in a timely manner and issue early warnings, thus enhancing safety.
