【摘要】 在联合收割机作业过程中,田间的树桩、石块等障碍物可能引发机器故障,这不仅影响了作业效率,而且可能会造成人员伤亡。为了适应今后联合收割机智能化的发展要求,以AT89C51单片机和超声波传感器为基础,提出了系统的设计思想,主要介绍了联合收割机的障碍物识别系统的硬件电路设计和软件设计。在联合收割机上采用此系统,可以使其达到所要求的避障目的。更多还原

【Abstract】 In the working process of combine, the obstacles, such as the stump, the stone in the field, may result in the mechanical breakdown. It has not only affected the work efficiency, but also caused the personnel casualty. In order to adapt the development of intelligent combine, this paper takes the AT89C51 CPU and the ultrasonic sensor as the foundation, proposes the system design ideas, and then mainly introduces the design of the hardware circuit and the program of the system of differentiating obstacle. This system is used on the combine; it can achieve the goal of avoiding a obstacle.更多还原
