Abstract

The invention provides a method and a system for weighing materials of an excavator, relates to the technical field of methods for obtaining the weight of materials in an excavator bucket, and solves a technical problem that calculation accuracy of the weight value of the materials in the excavator bucket is relatively low by a method in the prior art. The method comprises steps that first supporting force of the large-arm oil cylinder in all postures when a bucket is unloaded is obtained, and second supporting force of the large-arm oil cylinder in all postures when the bucket is loaded is obtained; angle parameters of all postures of the big arm are obtained; and the actual weight of the materials in the bucket is determined according to the obtained angle parameters of all postures of the big arm, the first supporting force and the second supporting force. The method is used for perfecting the excavator material weighing function and meets the requirement of people for accurately weighing the excavator material.

Description

technical field [0001] The invention belongs to the technical field of methods for obtaining the weight of materials in excavator buckets, and in particular relates to a method and system for weighing materials in an excavator. Background technique [0002] Excavator, also known as excavating machinery-excavating machinery-, also known as backhoe, is an earthmoving machine that uses buckets to dig materials higher or lower than the bearing surface, and loads them into transport vehicles or unloads them to the stockyard. The materials excavated by the excavator are mainly soil, coal, sediment, and pre-loose soil and rock. [0003] With the help of various signal sensors, the excavator weighing system can reflect real-time working height, working range, excavation weight, load overload and other information on the human-computer interaction interface, so that the lifting equipment can be safely and effectively operated within the range of its design parameters or use. When t...
