摘要
掘进机在掘进过程中悬臂位置的检测是掘进机自动控制的关键技术。利用掘进机在掘进过程中悬臂始终与竖直方向(或水平方向)成一定的角度,通过固定于悬臂上的三轴加速度传感器ADXL330的各个轴与重力方向之间的夹角就可以检测出掘进机悬臂的运动姿态,即可确定悬臂的位置。分析结果表明:与传统的利用线位移传感器检测液压油缸的行程来检测悬臂位移方式相比,采用三轴加速度传感器检测需要的传感器数量少,且检测结果不受掘进机在巷道中出现前后及左右倾斜的影响。
The detection of the boom position during the heading process of the mine roadheader was the key technology of the automatic control for the mine roadheader. With the boom always been a certain angle to the vertical ( or horizontal) direction during the mine heading process of the mine roadheader, the intersection angle between each axis and gravity direction could be applied to detect the movement postures of the mine roadheader's boom with of the triaxial acceleration sensor ADXL330 fit on the boom and to detect the position of the boom. The analysis showed that in comparison with the traditional linear displacement sensor applied to detect the stroke of the hydraulic cylinder for the detection of the boom displacement mode, the detection of the triaxial acceleration sensor would require less number of the sensors and the detection results of the triaxial acceleration sensor would not be influenced by the front or rear and right or left inclination of the mine roadheader in the mine roadway.
