The invention discloses an intelligent ploughing auxiliary system and method for an electric tractor, and relates to the field of intelligent ploughing of tractors. A visual soil type identification part is mainly used for acquiring a soil image through a camera and matching the soil image with a database to obtain an approximate soil type; after the approximate soil type is obtained, the soil type and the optimal slip rate threshold value are finally determined through further calculation and utilization of the adhesion coefficient by a slip rate soil identification part; whether a plough is collided or not is judged through a cultivated land detection and alarm part and a Logistic regression model, and when collision occurs, an alarm is given to remind a driver and stop the whole system; and a tilling depth control part controls an electric control suspension to adjust the tilling depth in real time according to the soil type and the determined optimal slip rate control threshold value. According to the intelligent ploughing auxiliary system and method, the soil type can be detected in real time, the slip rate threshold value can be obtained according to the soil type for tilling depth control, and the safety and high efficiency of tilling can be ensured.
本发明公开了一种电动拖拉机用智能犁耕辅助系统及方法,涉及拖拉机智能犁耕领域。通过视觉土壤类型识别部分主要通过摄像头采集土壤图像与数据库匹配获得大致土壤的类别。在获得的大致土壤类型后,由滑转率土壤识别部分进一步通过计算利用附着系数最终确定土壤类型及最佳滑移率门限值。通过耕地检测与报警部分通过Logistic回归模型判断犁具是否发生碰撞,当发生碰撞时,发出报警提醒驾驶员并停止整个系统工作。耕深控制部分根据土壤的类型及确定的最佳滑转率控制门限后,控制电控悬挂来实时调节耕深。本发明可以实时地检测土壤类型并根据土壤类型获得滑转率门限进行耕深控制,能保证耕地的安全性和高效性。
