摘要
目前深松作业的耕深测量主要以人工测量为主,测量精度和效率都比较低。为了提高深松作业过程中耕深测量的精度和效率,提出一种基于悬挂式深松机的耕深监测系统。建立耕深与下拉杆角度之间的数学模型,在下拉杆上安装角度传感器实时监测下拉杆的倾角数值,换算可得到实时的耕深。利用最小二乘法求解出数学模型的参数。分别进行了三次试验,并对每次试验分别拟合出一次曲线、二次曲线和三次曲线。结果表明,拟合的二次曲线可作为耕深与下拉杆角度之间的最优数学模型。
At present, the tilling depth measurement in subsoiling operation is mainly by manual measurement with low precision and efficiency. In order to improve the accuracy and efficiency of the measurement of tilling depth in the process of deep tillage, a tilling depth monitoring system based on the suspension subsoiler was proposed. The mathematical model between the tilling depth and the angle of the lower link was established. The Angle sensor was installed on the lower link to monitor the inclination value of the lower link in real time and real-time tilling depth can be obtained by conversion. The least square method was used to solve the parameters of the mathematical model. Three tests were carried out respectively fitting primary curve, quadric curve and cubic curve. The results show that the fitted quadric curve can be used as an optimal mathematical model between tillage depth and angle of pull rod.
