摘要
免耕播种机的排种装置靠地轮驱动,当地表覆有秸秆时,地轮的滑移不可避免,较大的滑移会造成漏播影响播种质量。为此,提出了一种基于单片机Atmega16的地轮滑移率的测试系统并对其进行了硬件和软件设计。通过光电开关和旋转编码器分别测量地轮的实际行驶距离和理论行驶距离,由单片机对数据进行处理并用液晶模块适时显示数据。
The seed-metering device of the no-tillage planter was driven by the ground wheel.Sliding was unavoidable when the ground was covered by the straw.High sliding brought seeding absence and affected the quality of sowing.In this paper,a monitoring system composed of hardware and software was designed based on ATMEGA16 Microcomputer.In the system,the practical and the theoretical driving distance of the ground wheel were measured by the photoelectric sensor and rotary encoder respectively.Then the sliding can be calculated and displayed on the LED.
