Engineering machinery operation method, operation terminal, control device and operation system

Abstract

The invention discloses an engineering machinery operation method, operation terminal, control device and operation system. The engineering machinery operation method includes the steps: building the same coordinate system of the operation terminal and engineering machinery by referring to a geodetic datum; acquiring and analyzing operation actuating signals of the operation terminal to determine operation information of the engineering machinery, and outputting the operation information to the engineering machinery control device. Therefore, the engineering machinery can be accurately controlled, operation is accurate and flexible, and operation errors caused by a handle or calibration are prevented.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a control method, a control terminal, a control device and a control system for a construction machine. Background technique [0002] At present, in the operation of construction machinery, especially multi-degree-of-freedom mechanical devices, it is generally operated through a remote control device with a handle. The operator needs to fully consider the attitude of the boom and the position of the construction machinery body to achieve The normal construction, and this operation has nothing to do with the position of the operator. Therefore, this requires the operator to have sufficient three-dimensional sense of space and skilled operating techniques, which virtually increases labor costs. Otherwise, once the operator does not have such professional quality, it will cause a lot of inconvenience during the construction process and affect the construction effect. [0003] F...

AI Technical Summary

Problems solved by technology

[0004] However, this method of operation has operational errors caused by manual calibration of the initial direction, and for general operators, it is prone to misoperation

Especially for construction machinery with poor maneuverability, if it is constructed at a high level, it is easy to cause waste of concrete or other construction materials, and it is easy to touch buildings or fences, etc., which causes a certain degree of waste

[0005] On the one hand, for the existing remote control devices with handles, the operator needs to operate several handles at the same time to move the end position, which is complicated and imprecise

On the other hand, for the operator, it is necessary to constantly consider information such as the position of the construction machinery and the attitude of the boom to realize the precise control of the pouring point at the end of the boom, which may easily lead to misoperation and construction waste
