AI Technical Summary

Technical Problem

Existing remote operating handles suffer mechanical wear due to contact sensors during high-frequency use, reducing control accuracy and service life. In addition, the interference capabilities and stability of inductive joysticks are insufficient.

Method used

A handle control method based on Hall sensors is used to achieve non-contact rocker data sensing. The driving environment of a real excavator is simulated through two three-degree-of-freedom handles, reducing the impact of mechanical wear and improving operating accuracy and stability.

Benefits of technology

It improves the service life and operating sensitivity of the handle, enhances the accuracy and presence of remote control, simulates the driving environment of a real excavator, and improves the operator's operating experience.
