基于ARM机器视觉的田间浇水设计

Field Watering Design Based on ARM Machine Vision

我国的农业机械化还处在起步阶段,特别是在浇水这一环节费时费力,机械化程度低,无法将浇水量控制在农作物生长所需要的最佳范围,浪费了水资源。针对这一情况,本文设计了一种基于ARM开发系统控制下的对农作物进行自动定量浇水的机器。该机在发动机的牵引下前进时,先由摄像头检测出垄上的植株位置,并通过数据线将所获取的数据传递给ARM板(ARM开发板,即以英国ARM (Advanced RISC Machines)公司的内核芯片作为CPU,同时附加其他外围功能的嵌入式开发板)。ARM板向继电器控制电路中发送控制信号,以控制电控开关的闭合,电磁阀得电打开完成浇水作业。通过试验表明该机作业性能稳定,运行平稳,易于操作,安全和调整维护方便简单,实现了对植物幼苗的自动化浇水,提高了作业效率。

China’s agricultural mechanization is still in its infancy, especially in watering which is time-consuming and labor-intensive, and low mechanized. It is impossible to control the amount of watering in the optimal range for the growth of crops and wastes water resources. In response to this situation, a machine for automatic quantitative watering of crops under the control of the ARM development system was designed. When the aircraft advances under the traction of the engine, the position of the plant on the ridge is detected by the camera, and the acquired data is transmitted to the ARM board through the data line (ARM development board, that is, using ARM (Advanced RISC Machines) company’s core chip as CPU, and other embedded peripheral development board). The ARM board sends a control signal to the control circuit of the relay to control the electronic control. The switch is closed and the solenoid valve is turned on to complete the watering operation. Through tests, it shows that the aircraft has stable operation performance, stable operation, easy operation, safety, convenient and simple adjustment and maintenance, automatic watering of plant seedlings, and improved work efficiency.
