Visual technology-based stone mine forklift with weight measuring function and weight measuring method of stone mine forklift

Abstract

The invention provides a visual technology-based stone mine forklift with a weight measuring function and weight measuring method of the stone mine forklift. The stone mine forklift comprises a forklift body and a weight measuring system, wherein the weight measuring system comprises an ARM main controller, a camera and two laser radars; the ARM main controller is connected with the camera and the two laser radars respectively; the camera is mounted in a center line in front of the forklift body; the two laser radars are also mounted in front of the forklift body and are symmetrically arranged on two sides of the camera; the camera and the two laser radars are located on the same horizontal line; and an imaging face of the camera and signal emission points of the laser radars are located on the same plane. According to the visual technology-based stone mine forklift, the camera and the laser radars are used as information acquisition means, so that the weight of rough stone blocks to be loaded or unloaded can be measured accurately, the phenomenon that the forklift is in overload operation due to inaccurate estimation of an operator is avoided, the accident rate is reduced, and the service life of the equipment is prolonged.

Description

【Technical field】 [0001] The invention relates to a forklift truck capable of measuring weight in stone mines based on vision technology and a method for measuring weight thereof. 【Background technique】 [0002] Stone mine forklift truck is a stone loading machine developed on the basis of the loader chassis. It is a construction machinery product in the loader market segment. The forklift truck integrates machine, electricity, instrument, hydraulic and digital information, and is highly efficient and energy-saving. It has the advantages of intelligence, good off-road performance, flexible use, safety and reliability, and high cost performance. It can replace forklifts, truck cranes, and excavators for scraping equipment for loading and unloading blocks in stone mine block yards. Replaced with a bucket, it can be used for digging mountains and repairing roads in stone mining areas, and shoveling mine surface soil, realizing its "one machine with two uses "Features. It is a...

AI Technical Summary

Problems solved by technology

However, the existing stone mine forklift trucks are not highly intelligent, and cannot automatically identify whether the stone blocks to be loaded and unloaded are overweight. At the same time, there is no good way to weigh the stone blocks to be loaded and unloaded. The experience of the staff is used to judge. In the process of actually loading and unloading stone mine blocks by forklift trucks, due to the high quality of stone blocks, the operators are roughly based on observing the volume and type of stone blocks and combining their own experience. Estimate the approximate mass of stone blocks to judge whether the blocks to be loaded and unloaded are overloaded

However, no matter how experienced the operator is, there will be mistakes in judgment, especially for the inexperienced novice, which will often overload the forklift truck, which will make its working devices and hydraulic system prone to failure. It will shorten the service life and reduce the reliability of the product; when overloaded for a long time or seriously overloaded, the accident rate will be greatly increased
