Combined Harvesters' Walking Velocity Analysis and Control System Design

联合收割机行走速度控制合理时,既能保证收割质量,又能提高生产效率,对其行走装置控制系统的研究是十分必要的。综合考虑影响收割机行走速度的各种因素,发现喂入量对其影响最大,因此所研究的联合收割机行走速度控制系统主要是基于喂入量的。系统根据喂入量大小的变化实时控制收割机的行走速度,保证其处于合理的范围之内,主要包括系统的硬件和软件设计两部分,其中硬件设计包含喂入量测定传感器的选择、行走速度的测定以及整个硬件结构工作流程。为此,针对硬件的功能对控制系统进行了相应软件模块的设计。

Combined harvesters walking speed control is reasonable,which can ensure the quality,and enhance their harvest production efficiency,thus to its control system walk device is very necessary.Comprehensive consideration of the influence of various factors combine harvester walking speed,we found that the feeding amount of its biggest influence,this article studies are made of combined harvesters walking speed control system is mainly based on the feeding amount.System according to the size of the feeding amount change the walking pace of real-time control harvester,ensure them to be in the reasonable scope.Mainly includes the system hardware and software design two bulks,including hardware design include feeding amount determination sensor selection,walking speed measuring and the hardware structure of workflow,according to the functions of the control system hardware carries on the corresponding software module design.
