为提高甜菜收获机械的自动化水平、减少漏挖损失,该文设计了甜菜收获机械的自动对行控制系统,应用Proteus软件设计了自动对行控制系统硬件电路图,应用Keil软件编写了系统的C语言控制程序,利用电子元器件对自动对行控制系统机械机构进行简化、模拟,并设置系统各元器件的参数,实现了在Proteus环境下自动对行控制系统的运行仿真;并进行了实验台和田间验证试验。结果表明,虚拟仿真试验的转动角度与实验台架试验的最大误差为2.78%,平均误差0.95%;与田间试验的最大误差为2.60%,平均误差1.30%。虚拟仿真结果与实验台、田间等试验结果基本一致,可为收获机械自动对行控制系统的设计研究提供参考。

In order to improve the automation level of beet harvest machinery, to reduce drain dug loss rate, this paper designed an autofollow row control system. It designed the hardware circuit diagram of the auto-follow row control system under the application of software Proteus, and it wrote the system control program in C language under the application of software Keil. This paper achieved the simulation of the auto-follow row control system in Proteus environment, by simplifying and simulating the mechanical mechanism of the auto-follow row control system using electronic components, setting the parameters of the components. It also conducted bench validation tests and field test. The results showed that, the maximum error of the rotation angle between virtual simulation experiment and bench test was 2.78%, the average error was 0.95%, and between virtual simulation experiment and field was 2.60%, the average error was 1.30%. Simulation results were almost consistent with the bench and field test results, so it can provides a reference for the design of auto-follow row control system employed in harvesting machinery.
