AI Technical Summary

Technical Problem

Existing AI-driven laser trackers equipped with precision positioning systems rely on a single encoder, which makes it impossible to independently monitor the actual rotational speed of the tracking head. They also lack hardware-level overspeed protection and absolute horizontal benchmark verification, resulting in vulnerability to electromagnetic interference and measurement error issues.

Method used

A speed monitoring mechanism is introduced, including a rotation component, a conversion component, a centrifugal force monitoring component, and a triggering component. It uses photoelectric sensors to provide an absolute horizontal reference, achieves independent speed monitoring and overspeed protection through mechanical structure, constructs redundant monitoring channels, and uses the principles of centrifugal force and spring mechanics to determine speed and provide graded alarms.

Benefits of technology

It enables precise speed monitoring and overspeed protection in electromagnetic interference environments, ensuring measurement accuracy and safety. It also provides absolute level calibration capability independent of the electronic system, improving system reliability and safety.
