Problems solved by technology

The real machine training period is long, the operation and maintenance cost is high, there is no difference in teaching, and there are certain security risks
The general simulation operation equipment only has the appearance of the excavator cab for students to be familiar with the operation device, but the static equipment has no actual training value
[0004] For this reason, those skilled in the art have designed a simulation operation device, but the simulation operation device in the prior art can provide pictures and simple swings in the form of a six-degree-of-freedom platform plus a display, and can simulate the working scene of a real machine, but the experience There is still a lack of sense, and it is impossible to obtain an action experience that is more in line with the actual work scene based on the operation of the personnel

Abstract

The invention discloses a control method and device for virtual excavators. The control method comprises the steps of acquiring an operation signal; generating an excavator action signal and a pictureconversion signal; inputting the excavator action signal into a washout algorithm model and enabling the washout algorithm model to output a simulation action signal; obtaining a pulse signal for controlling a servo system according to the simulation action signal; and enabling the servo system to receive the pulse signal and generate an action. According to the method, the excavator action signal is generated through the acquired operation signal, the excavator action signal is processed by utilizing the washout algorithm model so as to generate the simulation action signal, and finally thepulse signal for controlling the servo system is generated according to the simulation action signal, so that the action control of the servo system is realized, the action more accords with the practical operation experience and the action sensual experience of the users is effectively strengthened.

Description

technical field [0001] The invention relates to the technical field of virtual simulation, and more specifically relates to a control method and a control device of a virtual excavator. Background technique [0002] As we all know, the excavator is one of the common mechanical equipment in construction engineering. The operator of the excavator needs to study and train for a long time to be able to complete the operation of the excavator proficiently. [0003] At present, there are mainly the following methods of excavator operation training in China: 1. Real machine training; 2. Simulated operation equipment training. The real machine training period is long, the operation and maintenance cost is high, there is no difference in teaching, and there are certain security risks. The general simulation operation equipment only has the appearance of the excavator cab for students to be familiar with the operation device, but the static equipment has no actual training value. ...
