Excavator working stage and working condition identification method
The invention discloses an excavator working stage and working condition identification method which comprises the following steps: step 1, continuously detecting an excavator handle operation signal and a movable arm working angle signal, and judging and identifying the working stage of an excavator; the working stages comprise an excavation stage, a lifting rotation stage, an unloading stage and a reset rotation stage; 2, according to the characteristics of the working stage of the excavator, the working condition of the excavator is further recognized; the operation working conditions comprise a platform building working condition, a loading working condition and a squaring working condition. According to the technical scheme, the movable arm tilt angle sensor is additionally arranged, so that the recognition precision of the excavation stage and the platform building working condition is greatly improved; pressure change characteristics of an oil inlet and an oil outlet of the hydraulic motor are creatively used for identifying the loading working condition and the tossing working condition, and the problem of fuzzy judgment of the loading working condition and the tossing working condition is solved; programs are simple and clear, identification is accurate, the speed is high, and existing controller resources are not excessively occupied.
本发明公开了一种挖掘机工作阶段及工况识别方法，包括：步骤1，持续检测挖掘机手柄操作信号和动臂工作角度信号，判断并识别挖掘机的工作阶段；所述工作阶段包括：挖掘阶段、举升回转阶段、卸载阶段以及复位回转阶段；步骤2，根据挖掘机的工作阶段的特征，进一步识别挖掘机的作业工况；所述作业工况包括：搭台工况、装车工况和甩方工况。本发明技术方案通过增设动臂倾角传感器，极大的提高了挖掘阶段和搭台工况的识别精度；创造性的使用液压马达进油口和出油口的压力变化特征识别装车工况与甩方工况，解决了二者判定模糊的问题；程序简洁明了，识别准，速度快，不过多占用现有控制器资源。
