Excavator slope operation landslide early warning device, system and method
The invention discloses an excavator slope operation landslide early warning device, system and method, and belongs to the technical field of excavator test.The method includes the steps that when an excavator works on a slope, the angle of the slope, the angle of each executing mechanism, the torque of a rotary motor and the hydraulic pressure of each executing mechanism are obtained; calculating the attitude of the excavator and the output force of each execution mechanism based on the acquired data; the resistance borne by the excavator during operation, the gravity of the whole excavator, the first component force of the turning force in the direction of the slope and the friction force between the crawler and the ground are calculated; comparing the sum of the first component forces of the resistance, the gravity and the turning force in the slope direction with the friction force between the crawler and the ground, judging that a landslide exists, and detecting the landslide distance of the excavator when the landslide exists; and generating and outputting excavator landslide evaluation information, slope holding capacity information and landslide early warning information according to the landslide distance to remind a user. Accurate excavator slope operation information and early warning are provided for a driver or an intelligent terminal, and the driver and the excavator are protected.
本发明公开了一种挖掘机斜坡作业滑坡预警装置、系统及方法，属于挖掘机测试技术领域，方法为挖掘机斜坡作业时，获取所处斜坡角度、各执行机构角度、回转马达扭矩及各执行机构的液压压力；基于已获取数据而计算挖掘机姿态及各执行机构的输出力；从而计算出挖掘机作业受到的阻力、整机重力、回转力在所处斜坡方向上的第一分力及履带地面间摩擦力；将其阻力、重力及回转力在所处斜坡方向上的第一分力之和与履带地面间摩擦力对比，判断存在滑坡并在滑坡时检测挖掘机滑坡距离；根据滑坡距离生成挖掘机滑坡评估信息、驻坡能力信息及滑坡预警信息并输出，提醒用户。本发明为驾驶员或智能终端提供精确的挖掘机斜坡作业信息及预警，保护驾驶员和挖掘机。
