AI Technical Summary
Existing tunnel construction monitoring technologies suffer from low monitoring efficiency, long cycles, lack of self-position calibration mechanisms, limited early warning functions, and insufficient external linkage, making it difficult to achieve intelligent early warning and real-time monitoring across multiple scenarios.
A projection device that simultaneously projects multi-color invisible light, combined with a position calibration algorithm and an intelligent recognition model, enables synchronous monitoring of multiple sections. It also provides comprehensive early warning through an alarm system that links the inside and outside of the tunnel, including the identification of dangerous scenarios and non-standard construction practices.
It has achieved efficient and comprehensive monitoring of the tunnel face and surrounding environment, eliminated monitoring blind spots, improved monitoring accuracy and early warning capabilities, ensured timely transmission of danger information, and reduced the incidence of safety accidents.
