Excavator handle control system for remote operation

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.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of remote control driving, in particular to an excavator handle control system for remote operation. Background technique [0002] In the field of remote driving of excavators, the operating mechanism is an important interface for remote driving human-computer interaction, and its performance is the key to affecting the operator's operating experience. The operating mechanism at the remote control end is composed of an operating handle, pedals, etc. The sensors used in general operating handles are mostly potentiometers or photoelectric sensors, but the mechanical wear during use has a great impact on the service life of the handle. [0003] With the continuous development of robot technology, robots are widely used in industrial production, medical equipment, entertainment facilities, military, aerospace and other fields, which promotes the rapid development of modern society. As...

Problems solved by technology

[0006] The current remote control operating handle uses a sliding potentiometer to detect the action position of the handle, but because it uses a contact sensor, it is easy to cause mechanical wear under high-frequency use conditions, which makes the operating accuracy and smoothness of the handle decrease. Reduced handle life

The use of inductive joysticks has the characteristics of suppressing interference and insufficient stability.
