【摘要】：现有采煤机自动化割煤方法缺乏合适的数学模型及算法,无法实现长期、连续自动化割煤,制约了工作面自动化水平的提高。针对该问题,在三维坐标系中分析了采煤机姿态、位置与截割高度之间的函数关系,建立了基于静止坐标系和运动坐标系的采煤机运动方程,并提出了基于运动坐标系的双示范刀、单示范刀记忆割煤算法及具体实现方法。在锦界煤矿31112工作面应用单示范刀记忆割煤算法进行长期自动化割煤,实现了包括三角区在内的全工作面区域自动化割煤,证明了算法的正确性、可行性及鲁棒性。
[Abstract]:The existing automatic coal cutting methods of shearer are lack of suitable mathematical model and algorithm, which can not realize long-term and continuous automatic coal cutting, which restricts the improvement of working face automation level. In order to solve this problem, the paper analyzes the functional relationship between the attitude, position and cutting height of shearer in three-dimensional coordinate system, and establishes the motion equation of shearer based on static coordinate system and moving coordinate system. A memory coal cutting algorithm based on moving coordinate system and a single demonstration knife are presented. In 31112 face of Jinjie Coal Mine, single demonstration knife memory algorithm is used to carry out automatic coal cutting for a long time. The automatic coal cutting in the whole working face, including triangle area, is realized, and the correctness, feasibility and robustness of the algorithm are proved.
