Excavator precision work control method, system and excavator

Abstract

The invention discloses an excavator precision work control method, a system and an excavator. The excavator precision work control method comprises the steps of establishing a first coordinate systemadopting an upper car body rotation point of the excavator as an original point, and a second coordinate system adopting a reference point as an original point; through moving the original point in the first coordinate system to the original point of the second coordinate system, obtaining a conversion relation between the two coordinate systems, so that a coordinate value of a limited point in the second coordinate system is converted into a coordinate value in the first coordinate system, and a limited boundary of the excavator during work can be further obtained; and determining and displaying a relation between the excavator and the limited boundary according to a detection parameter of a sensor. The excavator provided by the invention is elaborate in design and simple to control, andan operator can accurately know a control range without the need for carrying out auxiliary operation such as measurement by another operator and extra measurement equipment, so that the work efficiency can be improved, the labor cost is reduced, the operation time and the fuel consumption are saved, and meanwhile, the accuracy and the reliability of excavation operation are ensured.

Description

technical field [0001] The invention relates to the field of excavators, in particular to an excavator precision work control method, system and excavator. Background technique [0002] An excavator, also known as an excavating machinery or an excavator, is an earth-moving machine that uses a bucket to excavate materials that are higher or lower than the bearing surface, and load them into transport vehicles or unload them to the stockyard. [0003] When the excavator is working on site, it is entirely up to the operator to judge the working environment and the state of the road surface. If the excavator is working in an environment with limited conditions, such as beside a slope, in a tunnel, under a bridge or a high-voltage line, or among high-rise buildings in a city, the operation The operator must slow down and operate carefully to prevent accidents, the work efficiency is low, and the control is difficult. [0004] In the fine work environment, it is also necessary to...

[0003] When the excavator is working on site, it is entirely up to the operator to judge the working environment and the state of the road surface. If the excavator is working in an environment with limited conditions, such as beside a slope, in a tunnel, under a bridge or a high-voltage line, or among high-rise buildings in a city, the operation The operator must slow down and operate carefully to prevent accidents, the operation efficiency is low, and the control is difficult

[0004] In the fine work environment, it is also necessary to add an on-site surveyor to measure and evaluate the operation effects such as the depth, flatness, and slope angle of the operation, and guide the operator's actions. This kind of measurement, evaluation, operation, re-measurement, The process of re-evaluation and re-operation often needs to be repeated many times to meet the construction requirements. In this way, more personnel are required, the operation cycle is long, and the equipment is running for a long time. At the same time, energy consumption and emissions are increased.
