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.

Abstract

The embodiment of the invention provides an excavator handle control system for remote operation, a handle control method based on a Hall sensor is adopted, non-contact rocker data sensing is achieved, the influence of contact and movement abrasion on the service life of a handle is reduced, and the excavator handle control system has the advantages of being high in sensitivity and good in performance; the handle mechanism is more flexible to operate, and the service life of the handle is prolonged; a two-hand cooperative control mode is adopted, and two three-degree-of-freedom handles are used for simulating the driving environment of a real excavator, so that a good remote control effect is achieved, and the feeling of presence of an operator in the remote operation process is improved; the operation habits of a driver are fully considered, the walking and working of the excavator are respectively controlled through combination of different degrees of freedom of the left hand handle and the right hand handle, an operating lever of the real excavator is simulated in the aspects of structure, motion degree of freedom and working range, and the man-machine interaction environment of excavator driving is restored.
