收获机智能滚筒转速表的改进设计研究

DESIGN AND STUDY OF IMPROVING ON THE INTELLECTIVE ROLLER TACHOMETER FOR COMBINE

对前期研制的收获机智能滚筒转速表的改进设计进行了论述，原设计采用数码管ＬＥＤ显示器显示滚筒转速，改进后的设计采用液晶显示器ＬＣＤ显示滚筒转速。

In this paper, the design of improving on the intellective roller tachometer for combine which has been developed before is discussed. The Low Emitting Diode shows the roller rotational speed in the former design .Now, the Liquid Crystal Display shows the roller rotational speed in the design improved, and it even more suits under the condition of pointblank sunlight in the field.
